WEBVTT 00:00:07.880 --> 00:00:10.759 You're in the bay. Once you get over to the bed, 00:00:10.919 --> 00:00:13.560 we'll give you the story. Everything's going 00:00:13.560 --> 00:00:17.339 to happen super fast. Welcome to the emergency 00:00:17.339 --> 00:00:45.020 room. You know usually when we talk about a medical 00:00:45.020 --> 00:00:47.560 diagnosis, there's this expectation of precision. 00:00:47.759 --> 00:00:50.100 It's almost like engineering. Right, yeah. Like 00:00:50.100 --> 00:00:52.340 it should be black and white. Exactly. You break 00:00:52.340 --> 00:00:54.859 your arm, the x -ray shows that jagged white 00:00:54.859 --> 00:00:56.700 line, and the doctor just points at it and says, 00:00:56.740 --> 00:01:00.219 you know, there it is, broken. It's binary. You 00:01:00.219 --> 00:01:02.420 look at the film, you see the fracture, you cast 00:01:02.420 --> 00:01:06.939 it. It's clean and, well... comforting because 00:01:06.939 --> 00:01:10.060 we really like things to be visible and easily 00:01:10.060 --> 00:01:11.799 categorized. But then you step into the world 00:01:11.799 --> 00:01:14.519 of obstetrical nursing and suddenly that x -ray 00:01:14.519 --> 00:01:17.579 machine is just, well it's broken. Oh completely. 00:01:17.700 --> 00:01:19.859 We are looking at a clinical landscape that is 00:01:19.859 --> 00:01:22.000 honestly pretty murky. I mean you have two patients 00:01:22.000 --> 00:01:24.760 inside one body. Yes and they are communicating 00:01:24.760 --> 00:01:27.280 through a hidden organ. Like placenta. Right. 00:01:27.659 --> 00:01:29.859 And things can change from perfectly expected 00:01:29.859 --> 00:01:32.319 to a life -threatening emergency in the span 00:01:32.319 --> 00:01:35.260 of, like, a single heartbeat. So if you are listening 00:01:35.260 --> 00:01:37.599 right now, you are likely a nursing student, 00:01:37.819 --> 00:01:40.159 maybe a new orientee, or someone preparing to 00:01:40.159 --> 00:01:42.760 tackle their OB exams. And you are entering one 00:01:42.760 --> 00:01:45.299 of the most dynamic, challenging, and honestly 00:01:45.299 --> 00:01:47.739 rewarding specialties in all of health care. 00:01:47.879 --> 00:01:50.040 It really is. Our mission for this deep dive 00:01:50.040 --> 00:01:52.840 is to sift through the massive stack of obstetrical 00:01:52.840 --> 00:01:56.159 nursing source material we have and apply the 00:01:56.159 --> 00:01:58.739 80 -20 Pareto principle. Which is so needed because 00:01:58.739 --> 00:02:00.920 the textbooks are just huge. They are massive. 00:02:01.180 --> 00:02:03.319 So we are going to extract the highest yield, 00:02:03.640 --> 00:02:06.939 most testable, and most critical clinical pearls. 00:02:07.370 --> 00:02:09.729 I am not here to read you a textbook. Thank goodness. 00:02:09.949 --> 00:02:13.150 I am here to help you pass your exams and more 00:02:13.150 --> 00:02:15.930 importantly to help you become a safe prioritized 00:02:15.930 --> 00:02:18.909 future nurse. And I am here as your enthusiastic 00:02:18.909 --> 00:02:22.110 study buddy, the one who loves taking these massive 00:02:22.110 --> 00:02:24.810 overwhelming concepts and turning them into analogies 00:02:24.810 --> 00:02:26.789 that you know actually make sense. And sitting 00:02:26.789 --> 00:02:29.050 across from you as well, I like to think of myself 00:02:29.050 --> 00:02:32.830 as your elite OB clinical mentor and exam coach. 00:02:32.930 --> 00:02:36.009 So how exactly are we going to tackle this mountain 00:02:36.009 --> 00:02:38.009 of information today? Well, we are going to set 00:02:38.009 --> 00:02:40.810 some strict ground rules right off the bat. We're 00:02:40.810 --> 00:02:43.409 going to focus relentlessly on safety priority 00:02:43.409 --> 00:02:46.349 interventions. So think airway bleeding, fetal 00:02:46.349 --> 00:02:50.349 distress, and those classic tricky exam traps 00:02:50.349 --> 00:02:52.669 that test writers absolutely love to use. Oh, 00:02:52.669 --> 00:02:55.229 they love a good trap. They really do. We are 00:02:55.229 --> 00:02:58.139 going to separate the expected from the concerning, 00:02:58.699 --> 00:03:00.819 focus on what requires immediate follow -up, 00:03:01.120 --> 00:03:03.060 and build your clinical judgment so you aren't 00:03:03.060 --> 00:03:05.699 just memorizing random facts. You will learn 00:03:05.699 --> 00:03:08.639 to actually see the pattern. Seeing the patterns 00:03:08.639 --> 00:03:12.120 instead of just drowning in a sea of flashcards. 00:03:12.180 --> 00:03:14.300 I absolutely love that. It's the only way to 00:03:14.300 --> 00:03:17.219 survive nursing school, honestly. So true. So 00:03:17.219 --> 00:03:19.900 before we get into the dramatic emergencies of 00:03:19.900 --> 00:03:22.159 the delivery room, it makes sense to start with 00:03:22.159 --> 00:03:24.819 the chronological beginning of a potential crisis. 00:03:25.099 --> 00:03:26.939 Right, the early start. Yeah, what happens when 00:03:26.939 --> 00:03:29.500 the biological clock goes off, well, too early? 00:03:29.699 --> 00:03:31.719 We have to start the preterm puzzle. Preterm 00:03:31.719 --> 00:03:33.900 labor and the medications we use to manage it. 00:03:34.280 --> 00:03:36.819 Let's look at the absolute high -yield core must 00:03:36.819 --> 00:03:39.539 -knows here. Okay, lay it on me. We define preterm 00:03:39.539 --> 00:03:43.199 labor as the onset of regular uterine contractions 00:03:43.199 --> 00:03:46.560 that cause actual cervical change prior to 37 00:03:46.560 --> 00:03:49.050 weeks of gestation. The key phrase there seems 00:03:49.050 --> 00:03:51.370 to be cervical change, right? Because you have 00:03:51.370 --> 00:03:54.330 to differentiate true preterm labor from Braxton 00:03:54.330 --> 00:03:56.550 Hicks contractions. I know a lot of people think 00:03:56.550 --> 00:03:59.650 like any contraction before 37 weeks is an absolute 00:03:59.650 --> 00:04:01.909 crisis. That is a very common misconception. 00:04:03.050 --> 00:04:05.189 Braxton Hicks contractions might feel uncomfortable, 00:04:05.409 --> 00:04:07.629 like a tightening across the belly, but they 00:04:07.629 --> 00:04:10.150 lack a regular established pattern. So they're 00:04:10.150 --> 00:04:13.669 just random. Right. But most importantly, they 00:04:13.669 --> 00:04:17.339 do not result in cervical change. True preterm 00:04:17.339 --> 00:04:20.600 labor causes the cervix to shorten, soften, and 00:04:20.600 --> 00:04:23.240 dilate. OK, so it physically alters the anatomy. 00:04:23.480 --> 00:04:26.399 Precisely. If a client comes in at, say, 32 weeks 00:04:26.399 --> 00:04:28.639 complaining of some cramping, you cannot just 00:04:28.639 --> 00:04:31.259 look at the tokay demometer on the fetal monitor, 00:04:31.779 --> 00:04:34.600 see some uterine irritability, and definitively 00:04:34.600 --> 00:04:37.000 diagnose preterm labor. You have to look for 00:04:37.000 --> 00:04:38.740 that physical cervical change. Why does uterus 00:04:38.740 --> 00:04:40.879 even do that? I mean, why practice with Braxton 00:04:40.879 --> 00:04:42.519 Hicks if it's not time for the baby to come out? 00:04:42.600 --> 00:04:44.660 It is essentially the uterine muscle maintaining 00:04:44.660 --> 00:04:47.680 its tone. The uterus is a massive muscle and 00:04:47.680 --> 00:04:49.680 it needs to be primed and ready for the marathon 00:04:49.680 --> 00:04:52.879 of labor. Like stretching before a workout. Exactly 00:04:52.879 --> 00:04:56.100 like that. Braxton Hicks increased blood flow 00:04:56.100 --> 00:04:58.500 to the placenta and helped maintain the structural 00:04:58.500 --> 00:05:01.100 integrity of the uterine wall. But when those 00:05:01.100 --> 00:05:03.980 practice runs turn into a coordinated, rhythmic, 00:05:04.459 --> 00:05:06.639 and forceful pattern that actually pulls the 00:05:06.639 --> 00:05:10.009 cervix open prematurely, well... We have a massive 00:05:10.009 --> 00:05:12.449 problem. And looking at our sources, preterm 00:05:12.449 --> 00:05:14.970 birth affects about 10 % of births globally. 00:05:15.170 --> 00:05:17.509 It's incredibly common. Yeah, it is a massive 00:05:17.509 --> 00:05:19.670 driver of neonatal morbidity. But here's where 00:05:19.670 --> 00:05:23.029 my understanding gets a little, um, fuzzy. Okay, 00:05:23.269 --> 00:05:25.509 let's trip you up. The goal of treating preterm 00:05:25.509 --> 00:05:28.250 labor isn't necessarily to stop labor forever, 00:05:28.529 --> 00:05:30.639 is it? If we look at the clinical reality, you 00:05:30.639 --> 00:05:33.439 are absolutely right. In many cases, you cannot 00:05:33.439 --> 00:05:36.040 stop the biological train once it has truly left 00:05:36.040 --> 00:05:38.139 the station. So what are we trying to do? The 00:05:38.139 --> 00:05:40.879 primary goal of talkalytic therapy. So the medications 00:05:40.879 --> 00:05:44.100 we use to slow or stop contractions is actually 00:05:44.100 --> 00:05:46.639 incredibly modest. The goal is just to delay 00:05:46.639 --> 00:05:49.980 birth by at least 48 hours. Just 48 hours? That 00:05:49.980 --> 00:05:51.939 seems like we are setting the bar incredibly 00:05:51.939 --> 00:05:54.199 low. I mean, if they're at 30 weeks, why aren't 00:05:54.199 --> 00:05:56.079 we trying to keep the baby in there for another 00:05:56.079 --> 00:05:58.519 10 weeks? Because the medications we use to stop 00:05:58.519 --> 00:06:01.279 contractions are not benign. They have severe 00:06:01.279 --> 00:06:03.560 side effects for the maternal client. Oh, I see. 00:06:03.839 --> 00:06:06.259 And furthermore, sometimes the body is going 00:06:06.259 --> 00:06:09.540 into preterm labor for a reason, like an underlying 00:06:09.540 --> 00:06:12.579 infection, and keeping the fetus in a hostile, 00:06:12.899 --> 00:06:15.379 intruderent environment is actually more dangerous 00:06:15.379 --> 00:06:17.439 than just delivering early. That makes a lot 00:06:17.439 --> 00:06:20.540 of sense. So why 48 hours specifically? That 00:06:20.540 --> 00:06:24.139 48 hour window is highly specific. It is exactly 00:06:24.139 --> 00:06:26.819 the amount of time needed to administer corticosteroids 00:06:26.819 --> 00:06:29.259 to the maternal client. You're talking about 00:06:29.259 --> 00:06:32.699 betamethasone. Exactly. Those 48 hours give the 00:06:32.699 --> 00:06:35.279 betamethasone time to cross the placenta and 00:06:35.279 --> 00:06:37.639 enhance the formation of fetal lung surfactant. 00:06:37.709 --> 00:06:40.769 which is crucial for breathing. Yes, surfactant 00:06:40.769 --> 00:06:43.209 is the slippery substance inside the alveoli 00:06:43.209 --> 00:06:45.310 of the lungs that keeps them from collapsing 00:06:45.310 --> 00:06:48.569 every time the baby exhales. Premature babies 00:06:48.569 --> 00:06:51.230 lack surfactant, which is why respiratory distress 00:06:51.230 --> 00:06:53.509 syndrome is a primary cause of death in preterm 00:06:53.509 --> 00:06:55.850 infants. So we are literally just buying time 00:06:55.850 --> 00:06:58.170 to mature those lungs. Buying time, that's the 00:06:58.170 --> 00:07:00.000 perfect way to phrase it. It's like hitting the 00:07:00.000 --> 00:07:02.800 snooze button on a biological alarm clock. You 00:07:02.800 --> 00:07:05.079 know you can't sleep forever. You just need enough 00:07:05.079 --> 00:07:07.620 time to put on your armor, the beta -methasone, 00:07:07.920 --> 00:07:10.319 before you have to face the cold, harsh day outside. 00:07:10.560 --> 00:07:13.300 I really like that analogy. You are buying time 00:07:13.300 --> 00:07:17.079 for the armor. So as a nurse assessing a client 00:07:17.079 --> 00:07:20.600 who comes into triage, we need to separate the 00:07:20.600 --> 00:07:23.029 expected from the concerning. Right, because 00:07:23.029 --> 00:07:24.850 we don't want to panic over normal pregnancy 00:07:24.850 --> 00:07:27.949 pains. Exactly. Expected findings in the late 00:07:27.949 --> 00:07:30.170 second or early third trimester might include 00:07:30.170 --> 00:07:33.050 dull back aches or mild pelvic pressure as the 00:07:33.050 --> 00:07:35.810 baby grows. But what are the concerning findings 00:07:35.810 --> 00:07:37.910 that tell us this isn't just normal pregnancy 00:07:37.910 --> 00:07:40.410 discomfort? Well, the sources emphasize a cervical 00:07:40.410 --> 00:07:43.410 length of 25 millimeters or less on a transvaginal 00:07:43.410 --> 00:07:46.439 ultrasound. Yes, that's a huge red flag. A shortened 00:07:46.439 --> 00:07:48.819 cervix is highly predictive of preterm birth. 00:07:49.459 --> 00:07:51.680 The cervix is normally thick and long, acting 00:07:51.680 --> 00:07:53.860 as a physical barrier. Like a tightly closed 00:07:53.860 --> 00:07:56.740 door. Right. If it is effacing, thinning out 00:07:56.740 --> 00:07:59.360 to 25 millimeters or less, that physical barrier 00:07:59.360 --> 00:08:02.500 is failing, the door is opening. Another concerning 00:08:02.500 --> 00:08:05.199 finding and a massive exam focus is the fetal 00:08:05.199 --> 00:08:09.000 fibronectin or FFN test. Let's unpack the FFN 00:08:09.000 --> 00:08:11.339 test because it seems like a giant trap waiting 00:08:11.339 --> 00:08:16.040 to happen on an exam. What exactly is fetal fibronectin? 00:08:16.399 --> 00:08:18.839 Think of fetal fibronectin as a biological glue. 00:08:19.480 --> 00:08:22.319 It is a protein that physically binds the fetal 00:08:22.319 --> 00:08:24.920 amniotic sac to the maternal uterine lining. 00:08:25.240 --> 00:08:27.860 So it holds everything in place? Normally, yes, 00:08:27.939 --> 00:08:31.199 this glue stays intact and hidden. But if the 00:08:31.199 --> 00:08:33.379 physical relationship between the sac and the 00:08:33.379 --> 00:08:36.100 lining is being disrupted, like if there is inflammation 00:08:36.100 --> 00:08:39.059 or the cervix is starting to pull open, that 00:08:39.059 --> 00:08:41.879 glue starts to leak into the vaginal secretions. 00:08:42.159 --> 00:08:44.580 So if we swab the vagina and find this glue, 00:08:44.879 --> 00:08:47.539 it means things are starting to broke down. Precisely. 00:08:47.940 --> 00:08:50.360 But here is the major exam trap you absolutely 00:08:50.360 --> 00:08:53.279 must avoid. The predictive value of the FFN test 00:08:53.279 --> 00:08:56.279 is heavily skewed. Skewed how? If the FFN swab 00:08:56.279 --> 00:08:59.009 is negative, it is incredibly reliable. A negative 00:08:59.009 --> 00:09:01.669 test means it is highly unlikely, like less than 00:09:01.669 --> 00:09:04.070 a 1 % chance that the client will deliver in 00:09:04.070 --> 00:09:06.649 the next two weeks. Wow, less than 1%. Yeah, 00:09:06.649 --> 00:09:08.330 so you can confidently reassure them, provide 00:09:08.330 --> 00:09:09.990 education, and send them home. But what if it's 00:09:09.990 --> 00:09:12.070 positive? Does that mean the baby is coming today? 00:09:12.470 --> 00:09:15.590 And that's the trap. A positive FFN test is not 00:09:15.590 --> 00:09:17.870 a guarantee that they will deliver. It just means 00:09:17.870 --> 00:09:19.889 the glue is disturbed. Oh, I see. They might 00:09:19.889 --> 00:09:22.269 deliver in two days, or they might go full term 00:09:22.269 --> 00:09:26.009 to 40 weeks. A positive test just raises your 00:09:26.009 --> 00:09:29.519 level of suspicion. You cannot definitively diagnose 00:09:29.519 --> 00:09:32.720 imminent preterm labor based on a positive FFN 00:09:32.720 --> 00:09:35.360 alone. Okay. That makes perfect sense. Negative 00:09:35.360 --> 00:09:37.139 means you're safe for a couple of weeks. Positive 00:09:37.139 --> 00:09:39.100 just means, hey, we need to watch you closely. 00:09:39.419 --> 00:09:41.919 Exactly. Keep a close eye on them. So let's say 00:09:41.919 --> 00:09:44.860 they are exhibiting real cervical change and 00:09:44.860 --> 00:09:46.840 we need to hit that snooze button. Let's walk 00:09:46.840 --> 00:09:49.740 through the pharmacology, the big four preterm 00:09:49.740 --> 00:09:52.519 labor medications. This is pure exam gold right 00:09:52.519 --> 00:09:54.720 here. The first one you will frequently see is 00:09:54.720 --> 00:09:58.240 Tributylene. It is a beta -2 adrenergic agonist. 00:09:58.480 --> 00:10:00.940 Now I remember from basic pharmacology that beta 00:10:00.940 --> 00:10:02.980 -1 receptors are in the heart, you have one heart, 00:10:03.220 --> 00:10:04.899 and beta -2 receptors are in the lungs because 00:10:04.899 --> 00:10:08.000 you have two lungs. So tributylene is primarily 00:10:08.000 --> 00:10:11.039 targeting the lungs. It targets the lungs to 00:10:11.039 --> 00:10:14.100 cause bronchodilation, which is why it's historically 00:10:14.100 --> 00:10:17.100 been used as an asthma drug. But here is the 00:10:17.100 --> 00:10:20.740 critical obstetrical crossover. The smooth muscle 00:10:20.740 --> 00:10:24.259 of the uterus is also packed with beta -2 receptors. 00:10:24.460 --> 00:10:27.559 Oh wow, I didn't realize that. Yes. So when you 00:10:27.559 --> 00:10:30.100 give tributyline, it relaxes the bronchial smooth 00:10:30.100 --> 00:10:33.419 muscle, but it also forcefully relaxes the uterine 00:10:33.419 --> 00:10:35.759 smooth muscle, stopping the contractions. That 00:10:35.759 --> 00:10:38.139 sounds great for stopping labor. What's the catch? 00:10:38.480 --> 00:10:40.580 Because there's always a catch. Always a catch. 00:10:41.059 --> 00:10:43.759 The catch is receptor cross -reactivity. While 00:10:43.759 --> 00:10:46.480 Tributylene prefers beta -2 receptors in the 00:10:46.480 --> 00:10:49.299 high doses needed to stop labor, it spills over 00:10:49.299 --> 00:10:51.559 and stimulates the beta -1 receptors in the maternal 00:10:51.559 --> 00:10:54.500 heart. Oh no. Yeah, it basically slams the accelerator 00:10:54.500 --> 00:10:56.539 on the maternal heart rate. Which means the priority 00:10:56.539 --> 00:10:58.779 nursing assessment has to be cardiovascular. 00:10:58.980 --> 00:11:01.570 We have to check her pulse. Absolutely. The strict 00:11:01.570 --> 00:11:03.669 non -negotiable parameter you must memorize. 00:11:04.230 --> 00:11:06.149 You must hold tributylene if the maternal heart 00:11:06.149 --> 00:11:08.590 rate is greater than 120 beats per minute. Hold 00:11:08.590 --> 00:11:12.070 if HR is over 120. Got it. If you push this drug 00:11:12.070 --> 00:11:14.909 while she's already tachycardic, you risk putting 00:11:14.909 --> 00:11:17.669 her into a dangerous arrhythmia or even cardiac 00:11:17.669 --> 00:11:20.269 ischemia. Are there any other major risks with 00:11:20.269 --> 00:11:23.659 tributylene? Culmonary edema. Because it alters 00:11:23.659 --> 00:11:26.360 capillary permeability and cardiovascular dynamics, 00:11:26.779 --> 00:11:28.659 fluid can start backing up into the maternal 00:11:28.659 --> 00:11:31.539 lungs. So we need to listen to her chest. Yes. 00:11:32.360 --> 00:11:34.620 If your client on turbutylene starts complaining 00:11:34.620 --> 00:11:37.179 of shortness of breath, or you hear crackles 00:11:37.179 --> 00:11:39.899 in their lung bases, you stop the drug immediately 00:11:39.899 --> 00:11:42.220 and notify the provider. Hold for heart rate 00:11:42.220 --> 00:11:46.059 over 120. Watch for crackles in the lungs. Okay, 00:11:46.080 --> 00:11:49.120 what is the second medication? Navetumor. This 00:11:49.120 --> 00:11:51.330 is a calcium channel blocker. So going back to 00:11:51.330 --> 00:11:54.049 physiology, muscles need an influx of calcium 00:11:54.049 --> 00:11:56.850 to contract. If we block the calcin channels, 00:11:57.110 --> 00:11:59.529 the uterine muscle physically cannot fire and 00:11:59.529 --> 00:12:01.889 cramp up. Exactly right. It inhibits calcium 00:12:01.889 --> 00:12:04.690 ion influx across the smooth muscle cell membrane. 00:12:05.149 --> 00:12:07.889 The uterus relaxes. But just like tributylene, 00:12:07.990 --> 00:12:10.029 the medication doesn't only stay in the uterus. 00:12:10.190 --> 00:12:12.570 It goes everywhere. Right. What other smooth 00:12:12.570 --> 00:12:14.610 muscle in the body relies on calcium channels? 00:12:14.909 --> 00:12:17.470 The blood vessels. So if we relax the blood vessels, 00:12:17.649 --> 00:12:20.830 they dilate. And if they dilate, the blood pressure 00:12:20.830 --> 00:12:24.009 is going to drop. Yes. Maternal hypotension is 00:12:24.009 --> 00:12:26.809 the primary adverse effect here. Your priority 00:12:26.809 --> 00:12:29.809 action is checking the blood pressure before 00:12:29.809 --> 00:12:31.929 administering knife at a pan. That makes total 00:12:31.929 --> 00:12:34.809 sense. You also need to teach the client to change 00:12:34.809 --> 00:12:38.370 position slowly to avoid orthostatic hypotension. 00:12:38.509 --> 00:12:40.889 And do you remember the classic pharmacology 00:12:40.889 --> 00:12:43.929 dietary trap with nifedipin? Oh, grapefruit juice. 00:12:44.129 --> 00:12:46.169 You have to instruct the client not to consume 00:12:46.169 --> 00:12:48.769 grapefruit or grapefruit juice because it inhibits 00:12:48.769 --> 00:12:50.830 the liver enzyme that breaks down the drug leading 00:12:50.830 --> 00:12:54.110 to severe toxic levels of nifedipin in the blood. 00:12:54.590 --> 00:12:57.649 Spot on. The test writers love a grapefruit juice 00:12:57.649 --> 00:12:59.669 question. Now for the third medication, which 00:12:59.669 --> 00:13:02.960 is an absolute heavyweight in obstetrics. magnesium 00:13:02.960 --> 00:13:05.480 sulfate. Wait, magnesium sulfate? I always thought 00:13:05.480 --> 00:13:08.019 of magnesium as just like a daily vitamin supplement 00:13:08.019 --> 00:13:09.980 you take for muscle cramps or to help you sleep. 00:13:10.419 --> 00:13:13.159 Why are we giving a heavy metal IV drip to a 00:13:13.159 --> 00:13:15.799 pregnant woman in preterm labor? It's a great 00:13:15.799 --> 00:13:18.620 question and it's because intravenous magnesium 00:13:18.620 --> 00:13:21.620 sulfate is a potent central nervous system depressant. 00:13:21.789 --> 00:13:24.610 Oh, it depresses the CNS. Yes, it competes with 00:13:24.610 --> 00:13:27.190 calcium at the motor end plate, essentially blocking 00:13:27.190 --> 00:13:29.350 the transmission of nerve impulses to the muscles. 00:13:30.049 --> 00:13:33.269 In the context of preterm labor, it relaxes the 00:13:33.269 --> 00:13:36.009 smooth muscle of the uterus for tocolysis. But 00:13:36.009 --> 00:13:38.690 the sources also emphasize that we give it for 00:13:38.690 --> 00:13:40.909 the baby, not just the mom. Yes, and this is 00:13:40.909 --> 00:13:44.009 highly testable. If a preterm birth is deemed 00:13:44.009 --> 00:13:47.629 inevitable and imminent before 32 weeks, we run 00:13:47.629 --> 00:13:50.370 a magnesium sulfate drip for fetal neuroprotection. 00:13:51.139 --> 00:13:53.240 Neuroprotection, what does it do for the baby's 00:13:53.240 --> 00:13:56.259 brain? It stabilizes the cerebral blood vessels 00:13:56.259 --> 00:13:58.879 and reduces inflammation in the fetal brain, 00:13:59.500 --> 00:14:02.200 which significantly reduces the risk and severity 00:14:02.200 --> 00:14:05.320 of cerebral palsy in the premature newborn. That 00:14:05.320 --> 00:14:07.659 is absolutely fascinating. But if it's a central 00:14:07.659 --> 00:14:09.919 nervous system depressant... and we are running 00:14:09.919 --> 00:14:12.279 it systemically through the mother, aren't we 00:14:12.279 --> 00:14:14.700 depressing her nervous system too? We are, and 00:14:14.700 --> 00:14:17.620 that is exactly where the danger lies. Magnesium 00:14:17.620 --> 00:14:20.100 sulfate toxicity is one of the most heavily tested 00:14:20.100 --> 00:14:22.320 safety topics in all of nursing. So we need to 00:14:22.320 --> 00:14:24.399 be really careful with the dosing. Extremely 00:14:24.399 --> 00:14:27.399 careful. If the magnesium levels climb too high, 00:14:27.960 --> 00:14:30.539 everything in the maternal body slows down dangerously 00:14:30.539 --> 00:14:32.899 until it simply stops. I know there are very 00:14:32.899 --> 00:14:35.080 specific cut -off numbers we need to memorize 00:14:35.080 --> 00:14:37.820 for toxicity. Let's walk through what that looks 00:14:37.820 --> 00:14:40.480 like clinically. Picture the patient. You walk 00:14:40.480 --> 00:14:44.080 into the room, and she's lethargic. You take 00:14:44.080 --> 00:14:46.320 your reflex hammer to check her patella reflex, 00:14:46.600 --> 00:14:49.340 her deep tendon reflexes, or DTRs. Normally, 00:14:49.440 --> 00:14:52.399 those should be a 2 plus b. Right. Exactly. But 00:14:52.399 --> 00:14:55.740 if she's becoming toxic, those reflexes diminish 00:14:55.740 --> 00:14:58.799 because the nerve transmission is blocked. DTRs 00:14:58.799 --> 00:15:01.519 dropping to 1 plus or 0, meaning absent reflexes, 00:15:01.799 --> 00:15:04.600 is a massive red flag. So absent reflexes, what 00:15:04.600 --> 00:15:06.720 about her breathing? If the muscles are depressed, 00:15:06.899 --> 00:15:08.659 her diaphragm won't work as well, right? You're 00:15:08.659 --> 00:15:10.799 right on the money. You are watching for respiratory 00:15:10.799 --> 00:15:13.899 depression. Respirations dropping below 12 breaths 00:15:13.899 --> 00:15:16.000 per minute means the diaphragm is failing. And 00:15:16.000 --> 00:15:18.799 how is the drug cleared from the body? Because 00:15:18.799 --> 00:15:20.259 if her kidneys aren't working, she's going to 00:15:20.259 --> 00:15:23.379 build up to a toxic level much faster. Magnesium 00:15:23.379 --> 00:15:26.659 is excreted entirely by the kidneys, so you must 00:15:26.659 --> 00:15:30.320 meticulously monitor urine output. Ulgeria, which 00:15:30.320 --> 00:15:33.220 is urine output of less than 30 mmol per hour, 00:15:33.620 --> 00:15:35.779 tells you the kidneys are failing to clear the 00:15:35.779 --> 00:15:38.840 drug and toxicity is imminent. Let me summarize 00:15:38.840 --> 00:15:40.940 those parameters because they are vital. DTR 00:15:40.940 --> 00:15:43.779 is of 1 plus or 0, respiration is less than 12, 00:15:44.299 --> 00:15:46.379 urine output less than 30 mmol per hour. And 00:15:46.379 --> 00:15:48.299 if we draw a blood level, what number are we 00:15:48.299 --> 00:15:50.840 looking at? A therapeutic level is usually between 00:15:50.840 --> 00:15:54.779 4 and 7 mql. A level greater than 8 mL of UQL 00:15:54.779 --> 00:15:57.379 is considered toxic. If I see any of those signs, 00:15:57.440 --> 00:15:59.759 like if I walk in and she is breathing nine times 00:15:59.759 --> 00:16:02.480 a minute and has no reflexes, what is the immediate 00:16:02.480 --> 00:16:04.639 mechanical action? Do I call the doctor? You 00:16:04.639 --> 00:16:07.399 shut off the IV pump. You stop the infusion immediately. 00:16:07.519 --> 00:16:09.820 Right away. Yes. You do not call the provider 00:16:09.820 --> 00:16:11.960 first to ask permission. You stop the poison. 00:16:12.559 --> 00:16:14.799 Then you administer the antidote, which you should 00:16:14.799 --> 00:16:17.019 always have at the bedside when a client is on 00:16:17.019 --> 00:16:20.139 a magnesium drip. Calcium gluconate. Yes, because 00:16:20.139 --> 00:16:22.200 magnesium and calcium compete at the cellular 00:16:22.200 --> 00:16:25.220 level. Flooding the body with calcium overrides 00:16:25.220 --> 00:16:27.860 the magnesium blockade and restores nerve function. 00:16:28.340 --> 00:16:31.399 Okay, so we've covered terbutylene, nefetapine, 00:16:31.820 --> 00:16:35.179 and magnesium sulfate. The final of the big four 00:16:35.179 --> 00:16:37.299 medications is the armor we discussed earlier. 00:16:37.840 --> 00:16:40.419 Betamethasone. Correct. Betamethasone is given 00:16:40.419 --> 00:16:43.220 intramuscularly to the maternal client, usually 00:16:43.220 --> 00:16:46.159 in two doses, 24 hours apart. And this is the 00:16:46.159 --> 00:16:48.919 one that helps the baby's lungs? Yes. It stimulates 00:16:48.919 --> 00:16:51.279 the type 2 pneumocytes in the fetal lungs to 00:16:51.279 --> 00:16:53.580 produce that life -saving surfactant. All right. 00:16:53.580 --> 00:16:55.559 So let's shift our focus a bit. What happens 00:16:55.559 --> 00:16:58.840 if our tocolytic snooze button fails? Or worse, 00:16:59.240 --> 00:17:01.259 what happens if the protective bubble around 00:17:01.259 --> 00:17:03.879 the baby breaks before the client is even in 00:17:03.879 --> 00:17:06.640 labor? then we are entering the territory of 00:17:06.640 --> 00:17:09.559 PPROM preterm pre -labor rupture of membranes. 00:17:09.740 --> 00:17:12.900 That sounds intense. It is. The absolute must 00:17:12.900 --> 00:17:15.180 -know core here is understanding that the amniotic 00:17:15.180 --> 00:17:18.660 sac has ruptured before 37 weeks and before contractions 00:17:18.660 --> 00:17:20.859 have even started. The amniotic sac is supposed 00:17:20.859 --> 00:17:23.519 to be this perfectly sterile, temperature -controlled, 00:17:23.559 --> 00:17:26.039 sealed environment. It's the ultimate physical 00:17:26.039 --> 00:17:28.440 barrier. Exactly. Once it breaks, the door is 00:17:28.440 --> 00:17:30.339 wide open for bacteria to travel up from the 00:17:30.339 --> 00:17:33.019 vagina, through the cervix, and right into the 00:17:33.019 --> 00:17:35.440 uterus. And that leads to the most dangerous 00:17:35.440 --> 00:17:39.539 consequence of PPROM, chorionitis. This is a 00:17:39.539 --> 00:17:43.119 severe intra -amniotic infection. So the uterus 00:17:43.119 --> 00:17:46.240 basically gets infected. Yes. The fetal environment 00:17:46.240 --> 00:17:49.119 becomes a petri dish. The fetus can actually 00:17:49.119 --> 00:17:52.180 aspirate or swallow that infected fluid, leading 00:17:52.180 --> 00:17:55.799 to profound fetal sepsis, pneumonia, or meningitis 00:17:55.799 --> 00:17:59.299 before they are even born. Wow, that is terrifying. 00:17:59.680 --> 00:18:01.859 So we need to know the difference between expected 00:18:01.859 --> 00:18:05.460 amniotic fluid and fluid that screams infection. 00:18:05.799 --> 00:18:07.960 Expected amniotic fluid should be clear or pale 00:18:07.960 --> 00:18:10.180 yellow. And if you test the pH, it should be 00:18:10.180 --> 00:18:13.420 between 7 .1 and 7 .3. It is slightly alkaline. 00:18:13.519 --> 00:18:15.680 And concerning findings. You're looking for fluid 00:18:15.680 --> 00:18:18.299 that is foul smelling or fluid that is green 00:18:18.299 --> 00:18:20.519 or yellowish brown. Which indicates meconium 00:18:20.519 --> 00:18:22.940 staining, right? The baby has had a bowel movement 00:18:22.940 --> 00:18:25.579 in utero, which is a sign of severe fetal stress. 00:18:25.759 --> 00:18:28.519 Exactly. For choriomonaditis specifically, there 00:18:28.519 --> 00:18:30.859 is a classic triad of infection you must look 00:18:30.859 --> 00:18:33.160 for. Let me guess. Fever is one of them. Yes, 00:18:33.279 --> 00:18:35.460 maternal fever greater than 38 degrees Celsius 00:18:35.460 --> 00:18:38.720 or 100 .4 Fahrenheit, typically documented on 00:18:38.720 --> 00:18:40.420 two separate occasions. OK, what's the second 00:18:40.420 --> 00:18:43.319 sign? The second sign is severe uterine tenderness. 00:18:44.079 --> 00:18:45.960 The uterus will be painful to palpation, even 00:18:45.960 --> 00:18:48.660 between contractions, because the tissue is acutely 00:18:48.660 --> 00:18:51.440 inflamed. And the third sign? Fetal tachycardia. 00:18:51.549 --> 00:18:55.049 a baseline fetal heart rate consistently above 00:18:55.049 --> 00:18:58.890 160 beats per minute. In fact, fetal tachycardia 00:18:58.890 --> 00:19:02.450 is often the very first clinical sign of an introterine 00:19:02.450 --> 00:19:04.829 infection. Really? Before the mom even gets a 00:19:04.829 --> 00:19:07.410 fever? Yes. The baby's heart rate will speed 00:19:07.410 --> 00:19:09.829 up to try and circulate white blood cells in 00:19:09.829 --> 00:19:12.609 response to the invading bacteria, often hours 00:19:12.609 --> 00:19:14.809 before the maternal client ever spikes a fever. 00:19:14.930 --> 00:19:17.650 That is a phenomenal clinical, Pearl. The baby 00:19:17.650 --> 00:19:19.509 will tell you there is an infection before the 00:19:19.509 --> 00:19:23.019 mom's thermometer does. warning system. So let's 00:19:23.019 --> 00:19:25.279 play out a scenario. A client comes into triage 00:19:25.279 --> 00:19:27.759 at 32 weeks and says, I think my water broke. 00:19:27.880 --> 00:19:30.539 I feel a gush of fluid. As the nurse, what is 00:19:30.539 --> 00:19:33.200 my priority action? Do I immediately do a vaginal 00:19:33.200 --> 00:19:35.480 exam to see if she's dilating? Absolutely not. 00:19:35.519 --> 00:19:38.059 And this is a non -negotiable safety rule. If 00:19:38.059 --> 00:19:41.059 you suspect PPROM, you avoid digital vaginal 00:19:41.059 --> 00:19:43.700 exams unless birth is visibly imminent. Wait, 00:19:43.799 --> 00:19:46.059 really? Why? I thought checking the cervix was 00:19:46.059 --> 00:19:48.299 a standard protocol when someone comes in? Think 00:19:48.299 --> 00:19:51.720 about the anatomy. The vaginal canal is heavily 00:19:51.720 --> 00:19:54.640 colonized with normal healthy flora bacteria 00:19:54.640 --> 00:19:56.960 that belong there, but the uterus is supposed 00:19:56.960 --> 00:19:59.480 to be sterile. Oh, I see where this is going. 00:19:59.839 --> 00:20:02.339 Every time you introduce a gloved hand into the 00:20:02.339 --> 00:20:05.319 vaginal canal to check the cervix, you are physically 00:20:05.319 --> 00:20:08.279 pushing that vaginal bacteria upward toward the 00:20:08.279 --> 00:20:11.000 open unprotected cervix. So you're causing the 00:20:11.000 --> 00:20:13.160 infection. You dramatically increase the risk 00:20:13.160 --> 00:20:15.839 of ascending infection. We have documented cases 00:20:15.839 --> 00:20:18.519 where a perfectly stable PPROM patient develops 00:20:18.519 --> 00:20:21.660 raging chorioninitis simply because too many 00:20:21.660 --> 00:20:24.869 providers performed vaginal exams. Wow. You literally 00:20:24.869 --> 00:20:27.470 push the bacteria up the elevator shaft. That's 00:20:27.470 --> 00:20:29.430 a great visual. So if I can't use my fingers 00:20:29.430 --> 00:20:31.789 to check the cervix, how do I verify that her 00:20:31.789 --> 00:20:34.089 water actually broke? What if she just peed herself? 00:20:34.369 --> 00:20:36.170 Because let's be honest, bladder control at 32 00:20:36.170 --> 00:20:40.109 weeks is minimal. Very true. We use sterile speculum 00:20:40.109 --> 00:20:42.950 exams to visually inspect for pooling of fluid 00:20:42.950 --> 00:20:45.769 in the vaginal vault. And we use diagnostic tests 00:20:45.769 --> 00:20:48.210 on that fluid. The two classic tests you must 00:20:48.210 --> 00:20:50.150 know are the nitrosine test and the Fern test. 00:20:50.410 --> 00:20:52.410 I actually have a memory anchor for the nitrosine 00:20:52.410 --> 00:20:56.390 test. The swab reacts to the alkaline pH of amniotic 00:20:56.390 --> 00:20:59.390 fluid. Right. Normal vaginal secretions are acidic, 00:20:59.509 --> 00:21:03.089 right around a pH of 4 .5, but amniotic fluid 00:21:03.089 --> 00:21:07.250 is alkaline, above 7 .0, so my memory hook is 00:21:07.250 --> 00:21:10.289 nitrazine turns blue for baby. That is a perfect 00:21:10.289 --> 00:21:13.369 anchor. If the yellow nitrazine swab turns deep 00:21:13.369 --> 00:21:16.130 blue or blue green, it is highly indicative of 00:21:16.130 --> 00:21:18.829 amniotic fluid. The other test is the Fern test. 00:21:18.910 --> 00:21:20.869 How does that one work? You take a swab of the 00:21:20.869 --> 00:21:23.230 fluid from the vaginal pooling, smear it on a 00:21:23.230 --> 00:21:26.220 glass microscope slide, and let it dry. And then 00:21:26.220 --> 00:21:28.859 look at it under a microscope. Yes. Because amniotic 00:21:28.859 --> 00:21:31.640 fluid has a very specific concentration of sodium 00:21:31.640 --> 00:21:34.680 chloride and proteins, when it crystallizes as 00:21:34.680 --> 00:21:37.960 it dries, it forms a highly distinct branching 00:21:37.960 --> 00:21:40.380 pattern under the microscope that looks exactly 00:21:40.380 --> 00:21:42.980 like a fern leaf. OK. So we verified the water 00:21:42.980 --> 00:21:45.440 is broken prematurely. We suspect infection. 00:21:45.700 --> 00:21:48.059 We are anticipating orders for IV antibiotics, 00:21:48.440 --> 00:21:50.660 typically ampicillin and gentamicin. But looking 00:21:50.660 --> 00:21:52.880 at our sources, there is a massive exam trap 00:21:52.880 --> 00:21:55.400 regarding diagnosing this infection based on 00:21:55.400 --> 00:21:58.460 lab values. Yes, the white blood cell trap. Let's 00:21:58.460 --> 00:22:01.680 look at the physiology of pregnancy. A normal, 00:22:01.980 --> 00:22:05.559 non -pregnant adult has a WBC count of roughly 00:22:05.559 --> 00:22:08.200 4 ,500 to 11 ,000. Right, the standard range. 00:22:08.410 --> 00:22:11.009 But during pregnancy, the body naturally mounts 00:22:11.009 --> 00:22:14.190 a wild inflammatory response, and WBCs can normally 00:22:14.190 --> 00:22:16.730 elevate to 15 ,000. Even without an infection? 00:22:16.910 --> 00:22:19.289 Correct. And during the immense physical stress 00:22:19.289 --> 00:22:22.109 of active labor, it is entirely normal for the 00:22:22.109 --> 00:22:24.970 WBC count to spike all the way up to 25 ,000 00:22:24.970 --> 00:22:27.630 or even 30 ,000 without any infection present 00:22:27.630 --> 00:22:30.230 at all. And we just talked about giving betamethasone 00:22:30.230 --> 00:22:33.150 a corticosteroid. Steroids are famous for causing 00:22:33.150 --> 00:22:35.390 an artificial spike in white blood cells. Exactly. 00:22:35.490 --> 00:22:37.390 It's called demargination of white blood cells 00:22:37.390 --> 00:22:40.140 off the blood vessel walls. So if you get an 00:22:40.140 --> 00:22:42.019 exam question about a client with PPROM who has 00:22:42.019 --> 00:22:45.039 a WBC count of 18 ,000, you cannot automatically 00:22:45.039 --> 00:22:47.720 diagnose chorioemionitis based on that one lab 00:22:47.720 --> 00:22:49.880 value. It could just be the steroids. Exactly. 00:22:50.140 --> 00:22:52.680 Elevated WBCs alone do not equal infection in 00:22:52.680 --> 00:22:54.819 obstetrics. You must look for the clinical triad, 00:22:55.240 --> 00:22:57.519 the maternal fever, the uterine tenderness, and 00:22:57.519 --> 00:23:01.119 the fetal tachycardia. Don't let a high WBC count 00:23:01.119 --> 00:23:03.460 trick you if the patient is otherwise completely 00:23:03.460 --> 00:23:05.880 stable in a febrile. Okay, so once the water 00:23:05.880 --> 00:23:08.380 is broken, the clock is ticking on infection. 00:23:08.559 --> 00:23:11.420 It is. If labor isn't progressing adequately 00:23:11.420 --> 00:23:13.920 on its own to deliver the baby before infection 00:23:13.920 --> 00:23:16.460 sets in, the medical team has to step in to push 00:23:16.460 --> 00:23:19.019 the pace. Which brings us to the concepts of 00:23:19.019 --> 00:23:22.019 labor augmentation and the risks of oxytocin. 00:23:22.539 --> 00:23:24.819 The first thing we need to clarify is the terminology. 00:23:25.470 --> 00:23:28.890 Students often confuse induction and augmentation. 00:23:28.990 --> 00:23:30.710 What's the difference? Induction is starting 00:23:30.710 --> 00:23:33.069 labor from scratch, creating contractions in 00:23:33.069 --> 00:23:35.470 a patient who isn't having any. Augmentation 00:23:35.470 --> 00:23:37.549 is intervening to help labor progress when it 00:23:37.549 --> 00:23:40.230 has already begun spontaneously but has stalled 00:23:40.230 --> 00:23:42.690 out. Contractions have become weak or spaced 00:23:42.690 --> 00:23:45.049 too far apart. And the primary medication we 00:23:45.049 --> 00:23:47.630 use for both is intravenous oxytocin, commonly 00:23:47.630 --> 00:23:49.809 known by the brand name Peterson. But the sources 00:23:49.809 --> 00:23:52.009 highlight that oxytocin is a high alert medication 00:23:52.009 --> 00:23:54.490 that requires intensive one -to -one nursing. 00:23:54.690 --> 00:23:56.630 Yes, you cannot take your eyes off this patient. 00:23:56.890 --> 00:24:00.509 Why is it so dangerous? If oxytocin is just the 00:24:00.509 --> 00:24:03.069 synthetic version of the exact same hormone the 00:24:03.069 --> 00:24:05.650 posterior pituitary gland naturally makes to 00:24:05.650 --> 00:24:08.049 cause contractions, why do we have to monitor 00:24:08.049 --> 00:24:10.549 it so aggressively? It comes down to the difference 00:24:10.549 --> 00:24:13.089 between a finely tuned physiological feedback 00:24:13.089 --> 00:24:16.250 loop and a blunt medical intervention. I want 00:24:16.250 --> 00:24:18.910 you to visualize natural labor. Okay, visualizing. 00:24:19.029 --> 00:24:21.490 The brain releases a tiny pulse of oxytocin, 00:24:22.009 --> 00:24:24.529 the uterus contracts, the cervix stretches, which 00:24:24.529 --> 00:24:26.710 sends a signal back to the brain to release a 00:24:26.710 --> 00:24:29.210 little more. It self -regulates. It's a natural 00:24:29.210 --> 00:24:32.670 rhythm. And synthetic oxytocin. Synthetic oxytocin 00:24:32.670 --> 00:24:34.890 running through an IG pump is like hooking a 00:24:34.890 --> 00:24:37.349 fire hose to the uterus. It does not self -regulate. 00:24:37.509 --> 00:24:40.470 If you turn the IV rate up too high, the uterus 00:24:40.470 --> 00:24:42.529 is forced to contract too forcefully, too frequently, 00:24:42.650 --> 00:24:45.690 and for too long. But why is a super strong frequent 00:24:45.690 --> 00:24:48.130 contraction bad? Doesn't that just get the baby 00:24:48.130 --> 00:24:51.009 out faster? To understand why it's bad, you have 00:24:51.009 --> 00:24:53.130 to understand the anatomy of placental blood 00:24:53.130 --> 00:24:55.900 flow. Think of the uterus as a sponge filled 00:24:55.900 --> 00:24:58.559 with maternal blood, and the placenta is absorbing 00:24:58.559 --> 00:25:00.759 oxygen from that sponge. Okay, a blood sponge. 00:25:01.180 --> 00:25:03.720 Every time the uterus contracts, the muscle fibers 00:25:03.720 --> 00:25:06.380 tighten and physically squeeze the maternal blood 00:25:06.380 --> 00:25:09.900 vessels shut. So blood flow stops. Exactly. During 00:25:09.900 --> 00:25:12.460 a peak of every single contraction, blood flow 00:25:12.460 --> 00:25:16.500 to the placenta briefly ceases. The fetus experiences 00:25:16.500 --> 00:25:19.200 a temporary normal decrease in oxygen. It's like 00:25:19.200 --> 00:25:21.200 the baby is holding its breath. Which is why 00:25:21.200 --> 00:25:23.279 there needs to be a break between contractions. 00:25:23.420 --> 00:25:26.640 Yes. In a normal labor, there is a crucial rest 00:25:26.640 --> 00:25:29.220 period between contractions, the relaxation phase. 00:25:29.839 --> 00:25:32.119 During this rest, the uterine muscle loosens, 00:25:32.380 --> 00:25:34.880 the blood vessels open back up, the placenta 00:25:34.880 --> 00:25:37.740 refills with fresh oxygenated maternal blood, 00:25:37.960 --> 00:25:41.019 and the baby takes a breath. So to speak. Oh, 00:25:41.019 --> 00:25:43.799 I see where this is going. If we crank the oxytocin 00:25:43.799 --> 00:25:46.599 fire hose too high. You cause uterine tachycystally. 00:25:47.200 --> 00:25:50.059 Tachycystally. That sounds bad. It is. The clinical 00:25:50.059 --> 00:25:52.559 definition you must know is more than five contractions 00:25:52.559 --> 00:25:55.019 in a 10 -minute window averaged over 30 minutes. 00:25:55.420 --> 00:25:57.720 If the uterus is contracting six, seven, or eight 00:25:57.720 --> 00:26:00.099 times in 10 minutes, there is no relaxation phase. 00:26:00.160 --> 00:26:03.180 So the sponge never refills with blood. Exactly. 00:26:03.579 --> 00:26:06.039 You're effectively cutting off the baby's oxygen 00:26:06.039 --> 00:26:08.960 supply, leading to profound fetal hypoxia in 00:26:08.960 --> 00:26:11.460 acidemia. That is terrifying when you visualize 00:26:11.460 --> 00:26:14.059 the mechanics of it. So expected findings on 00:26:14.059 --> 00:26:15.900 the monitor would be contractions every two to 00:26:15.900 --> 00:26:18.900 three minutes, lasting roughly 60 to 90 seconds, 00:26:19.180 --> 00:26:21.500 with a clear resting tone in between. Correct. 00:26:21.960 --> 00:26:24.619 Concerning is that tachycystole. What is the 00:26:24.619 --> 00:26:27.380 priority action if we see more than five contractions 00:26:27.380 --> 00:26:30.079 in 10 minutes? This is a non -negotiable action. 00:26:30.140 --> 00:26:33.220 You stop the oxytocin infusion immediately. Turn 00:26:33.220 --> 00:26:35.339 it off completely. You not just turn the rate 00:26:35.339 --> 00:26:38.299 down by a few milliliters. You clamp the line 00:26:38.299 --> 00:26:41.019 and turn off the pump. you remove the stressor. 00:26:41.299 --> 00:26:44.460 OK, so we've established that oxytocin can suffocate 00:26:44.460 --> 00:26:47.099 the baby if we aren't careful. How do we actually 00:26:47.099 --> 00:26:49.079 know if the baby is holding its breath for too 00:26:49.079 --> 00:26:51.700 long? We have to read the fetal monitor. The 00:26:51.700 --> 00:26:54.000 continuous fetal heart rate strip is our only 00:26:54.000 --> 00:26:56.500 window into the neurological and respiratory 00:26:56.500 --> 00:26:58.619 well -being of the fetus. Let's break down reading 00:26:58.619 --> 00:27:01.839 the strip. What is considered normal? The expected 00:27:01.839 --> 00:27:04.619 baseline fetal heart rate should be between 110 00:27:04.619 --> 00:27:07.970 and 160 beats per minute. We want to see moderate 00:27:07.970 --> 00:27:09.829 variability. Variability meaning it shouldn't 00:27:09.829 --> 00:27:13.289 just be a flat line. Exactly. Variability is 00:27:13.289 --> 00:27:15.109 the beat -to -beat fluctuation in the heart rate. 00:27:15.690 --> 00:27:18.869 It should look slightly jagged. Good variability 00:27:18.869 --> 00:27:21.230 tells us the fetal autonomic nervous system is 00:27:21.230 --> 00:27:24.789 intact and oxygenated. And we want to see accelerations. 00:27:25.210 --> 00:27:26.990 Accelerations are when the heart rate temporarily 00:27:26.990 --> 00:27:29.569 jumps up, right? Like when the baby moves. Yes. 00:27:29.890 --> 00:27:31.930 Accelerations are always a good sign. They're 00:27:31.930 --> 00:27:33.690 the fatal equivalent of your heart rate going 00:27:33.690 --> 00:27:36.250 up when you jog up a flight of stairs. It proves 00:27:36.250 --> 00:27:39.410 the baby has oxygen reserves. But deviations 00:27:39.410 --> 00:27:42.289 from that baseline indicate trouble. We already 00:27:42.289 --> 00:27:45.009 mentioned that maternal fever causes fetal tachycardia. 00:27:45.450 --> 00:27:48.609 What about the drops in the heart rate? The decelerations. 00:27:49.029 --> 00:27:51.009 Decelerations are where clinical judgment is 00:27:51.009 --> 00:27:53.529 truly tested. When the heart rate drops in relation 00:27:53.529 --> 00:27:55.609 to the uterine contraction tells you exactly 00:27:55.609 --> 00:27:58.250 what the physiological problem is. Let's look 00:27:58.250 --> 00:28:00.529 at the three main types. Alright, get me. First, 00:28:00.869 --> 00:28:03.329 early decelerations. These mirror the contraction 00:28:03.329 --> 00:28:06.009 perfectly. As the contraction builds and goes 00:28:06.009 --> 00:28:08.549 up on the monitor, the fetal heart rate smoothly 00:28:08.549 --> 00:28:11.109 goes down. They hit their lowest point at the 00:28:11.109 --> 00:28:13.509 exact peak of the contraction and they recover 00:28:13.509 --> 00:28:15.910 back to baseline right as the contraction ends. 00:28:16.119 --> 00:28:19.720 What causes that perfect mirroring? It is a mechanical 00:28:19.720 --> 00:28:22.259 vagus nerve response. As the baby is pushed down 00:28:22.259 --> 00:28:24.980 the birth canal during a contraction, their head 00:28:24.980 --> 00:28:27.299 is compressed against the maternal pelvis. Oh, 00:28:27.339 --> 00:28:30.099 head compression. Yes. This physical head compression 00:28:30.099 --> 00:28:33.259 stimulates the fetal vagus nerve, which temporarily 00:28:33.259 --> 00:28:35.859 slows the heart rate. Because it is just a pressure 00:28:35.859 --> 00:28:38.839 response, it is a benign expected finding. It 00:28:38.839 --> 00:28:40.539 just means the baby is descending. You do not 00:28:40.539 --> 00:28:42.849 need to intervene. You just document it. Early 00:28:42.849 --> 00:28:46.029 equals head compression, expected. What about 00:28:46.029 --> 00:28:49.329 variable decelerations? Variables look very different. 00:28:49.690 --> 00:28:52.869 They are abrupt. They drop sharply, looking like 00:28:52.869 --> 00:28:54.970 Vs or Ws on the monitor strip. Like a sudden 00:28:54.970 --> 00:28:57.789 cliff? Exactly. They can happen at any time with 00:28:57.789 --> 00:29:00.150 or without a contraction. They indicate chord 00:29:00.150 --> 00:29:02.430 compression. So the umbilical cord is being squeezed? 00:29:02.650 --> 00:29:04.789 Yes, the umbilical cord is being physically squeezed. 00:29:05.029 --> 00:29:07.650 Maybe the baby is grabbing it or lying on it 00:29:07.650 --> 00:29:10.319 or the fluid is low. It temporarily cuts off 00:29:10.319 --> 00:29:13.019 blood flow, causing a sudden spike in fetal blood 00:29:13.019 --> 00:29:15.680 pressure, which triggers baroreceptors to abruptly 00:29:15.680 --> 00:29:18.359 tank the heart rate. Variable equals cord compression. 00:29:19.140 --> 00:29:22.079 And the third type. The most dangerous. Late 00:29:22.079 --> 00:29:25.700 decelerations. These are subtle but ominous. 00:29:26.200 --> 00:29:27.980 They start after the peak of the contraction, 00:29:28.200 --> 00:29:30.519 and the heart rate doesn't recover until well 00:29:30.519 --> 00:29:32.599 after the contraction is completely over. Why 00:29:32.599 --> 00:29:35.759 do they happen late? It indicates placental insufficiency. 00:29:36.359 --> 00:29:39.059 The placenta is failing to deliver adequate oxygen. 00:29:39.500 --> 00:29:41.160 During the contraction, the maternal blood flow 00:29:41.160 --> 00:29:43.460 stops, as we discussed earlier. Right, the sponges 00:29:43.460 --> 00:29:46.839 squeeze dry. Exactly. A healthy fetus has enough 00:29:46.839 --> 00:29:49.000 oxygen reserve to coast through that temporary 00:29:49.000 --> 00:29:51.960 pause. But a fetus with a failing placenta does 00:29:51.960 --> 00:29:54.359 not have reserves. By the time the contraction 00:29:54.359 --> 00:29:57.140 reaches its peak, the fetus has completely run 00:29:57.140 --> 00:30:00.690 out of oxygen. Hypoxia sets in, chemoreceptors 00:30:00.690 --> 00:30:03.150 detect the rising carbon dioxide, and the heart 00:30:03.150 --> 00:30:05.710 rate drops late in the cycle. Late equals placental 00:30:05.710 --> 00:30:08.849 insufficiency. So, when we see these non -reassuring 00:30:08.849 --> 00:30:11.549 patterns, especially recurrent late decelerations 00:30:11.549 --> 00:30:14.589 or severe variable decelerations, what are our 00:30:14.589 --> 00:30:17.490 priority nursing actions? You must act systematically 00:30:17.490 --> 00:30:20.170 to restore oxygen to the fetus. We call this 00:30:20.170 --> 00:30:23.390 intraoderm resuscitation. Here's the exact prioritized 00:30:23.390 --> 00:30:25.650 sequence you need to drill into your mind. Okay, 00:30:25.809 --> 00:30:30.400 step one. Step one. Stop the oxytocin. If you 00:30:30.400 --> 00:30:32.640 are artificially stimulating the uterus to clamp 00:30:32.640 --> 00:30:35.559 down on the placenta, you must remove that stressor 00:30:35.559 --> 00:30:37.940 immediately. Makes sense. Stop the stress. Step 00:30:37.940 --> 00:30:41.759 two. Step two. Reposition the client. Turn them 00:30:41.759 --> 00:30:44.720 to their left or right lateral side. Let's talk 00:30:44.720 --> 00:30:47.099 about the physics of that. Why does turning them 00:30:47.099 --> 00:30:50.539 on their side help? Because of the maternal inferior 00:30:50.539 --> 00:30:54.039 vena cava. When a pregnant person lies flat on 00:30:54.039 --> 00:30:57.170 their back, the heavy, gravid uterus compresses 00:30:57.170 --> 00:30:59.470 the vena cava against the spine. Which pinches 00:30:59.470 --> 00:31:02.009 the vein shut. Yes. This traps blood in the lower 00:31:02.009 --> 00:31:04.210 extremities and prevents it from returning to 00:31:04.210 --> 00:31:06.650 the maternal heart. If blood isn't returning 00:31:06.650 --> 00:31:09.109 to the heart, it can't be pumped out to the placenta. 00:31:10.049 --> 00:31:12.150 Turning them on their side physically lifts the 00:31:12.150 --> 00:31:14.670 uterus off the vein, restoring cardiac output 00:31:14.670 --> 00:31:16.529 and placental perfusion. And it might shift the 00:31:16.529 --> 00:31:18.730 baby off the cord too, right? Exactly. which 00:31:18.730 --> 00:31:20.670 might relieve physical pressure on a compressed 00:31:20.670 --> 00:31:23.430 umbilical cord. Stop pitocin. Turn the patient. 00:31:23.630 --> 00:31:25.769 What is step three? Increase the rate of the 00:31:25.769 --> 00:31:28.549 primary 5e isotonic fluid. You open the fluids 00:31:28.549 --> 00:31:31.910 wide to give a rapid bolus. To expand the maternal 00:31:31.910 --> 00:31:34.349 blood volume, which pushes more pressure into 00:31:34.349 --> 00:31:36.809 the placenta. Precisely. Now, what do you think 00:31:36.809 --> 00:31:39.630 about oxygen? Honestly, it feels like oxygen 00:31:39.630 --> 00:31:43.289 should be step one. If the baby is hypoxic, give 00:31:43.289 --> 00:31:46.250 the mom an oxygen mask. And that is a massive, 00:31:46.430 --> 00:31:50.250 outdated exam trap. Wait, really? Yes. We used 00:31:50.250 --> 00:31:52.890 to throw a 10 -liter non -rebreather mask on 00:31:52.890 --> 00:31:54.750 every client at the first sign of a dip in the 00:31:54.750 --> 00:31:57.750 heart rate. But modern evidence -based practice 00:31:57.750 --> 00:32:00.650 has changed this entirely. Oxygen is no longer 00:32:00.650 --> 00:32:03.250 the automatic first step. Why not? If the baby 00:32:03.250 --> 00:32:05.730 lacks oxygen, why not supply it? Because you 00:32:05.730 --> 00:32:07.849 have to fix the mechanics of the plumbing before 00:32:07.849 --> 00:32:10.430 you worry about the gas supply. Think about it. 00:32:10.650 --> 00:32:13.630 The umbilical cord is physically squeezed shut 00:32:13.630 --> 00:32:16.549 -like in a variable deceleration. Giving the 00:32:16.549 --> 00:32:18.829 maternal client 10 liters of oxygen won't help 00:32:18.829 --> 00:32:21.250 the fetus at all because the oxygenated blood 00:32:21.250 --> 00:32:23.210 cannot get past the kink in the hose. Well, that 00:32:23.210 --> 00:32:25.990 makes so much sense. You have to fix the mechanical 00:32:25.990 --> 00:32:29.230 perfusion problem first. You reposition the client 00:32:29.230 --> 00:32:32.250 to unkink the cord. You give fluids to fix the 00:32:32.250 --> 00:32:35.650 maternal blood volume. You only administer supplemental 00:32:35.650 --> 00:32:38.349 oxygen if those initial mechanical interventions 00:32:38.349 --> 00:32:40.910 fail to improve the fetal heart rate. Fix the 00:32:40.910 --> 00:32:43.650 plumbing, then supply the gas. That is a brilliant 00:32:43.650 --> 00:32:46.240 way to remember it. So while light decelerations 00:32:46.240 --> 00:32:48.400 give us a warning that the placenta is slowly 00:32:48.400 --> 00:32:50.920 failing, sometimes the plumbing problems are 00:32:50.920 --> 00:32:53.640 sudden, dramatic, and require an immediate rapid 00:32:53.640 --> 00:32:56.799 response. We are moving into the red flag mechanical 00:32:56.799 --> 00:33:00.029 emergencies. cord prolapse and shoulder dystocia. 00:33:00.029 --> 00:33:03.289 Oh boy. These are your absolute drop everything 00:33:03.289 --> 00:33:05.809 emergencies. They are the highest stakes prioritization 00:33:05.809 --> 00:33:08.029 questions on any exam because when these happen, 00:33:08.650 --> 00:33:10.990 minutes literally equal brain cells. Let's start 00:33:10.990 --> 00:33:13.750 with cord prolapse. The visual here is horrifying. 00:33:14.130 --> 00:33:16.410 The umbilical cord slips out of the cervix before 00:33:16.410 --> 00:33:18.829 the baby's head. When the massive hard skull 00:33:18.829 --> 00:33:21.190 of the baby comes down into the pelvis, it acts 00:33:21.190 --> 00:33:23.450 like a giant boulder crushing the cord against 00:33:23.450 --> 00:33:26.170 the maternal pelvic bone. It instantly cuts off 00:33:26.170 --> 00:33:29.599 100 % of the fetal circulation. It is catastrophic 00:33:29.599 --> 00:33:32.000 if not managed within seconds. It most often 00:33:32.000 --> 00:33:34.259 happens right after the amniotic sac ruptures, 00:33:34.599 --> 00:33:36.720 especially if the baby's head wasn't fully engaged 00:33:36.720 --> 00:33:39.779 in the pelvis yet. The fluid gushes out like 00:33:39.779 --> 00:33:42.339 a waterfall and it washes the lightweight umbilical 00:33:42.339 --> 00:33:45.039 cord down with it. Put me in the room. I am the 00:33:45.039 --> 00:33:47.799 nurse. I do a vaginal exam right after the water 00:33:47.799 --> 00:33:50.019 breaks and instead of feeling a hard fetal skull, 00:33:50.160 --> 00:33:53.319 I feel a soft pulsating rope -like structure. 00:33:53.680 --> 00:33:56.000 What do I do? Your hand stays exactly where it 00:33:56.000 --> 00:33:58.019 is. You do not pull it out. Leave my hand in. 00:33:58.200 --> 00:34:01.759 Yes. You use your sterile, gloved fingers to 00:34:01.759 --> 00:34:04.240 manually push the baby's presenting part, the 00:34:04.240 --> 00:34:06.740 head OP, and off the umbilical cord. You are 00:34:06.740 --> 00:34:08.760 physically lifting the boulder off the hose. 00:34:08.860 --> 00:34:10.840 Wait, I stay there. How long? You stay there 00:34:10.840 --> 00:34:13.039 until the baby is delivered. You will literally 00:34:13.039 --> 00:34:15.659 climb onto the bed, riding on all fours with 00:34:15.659 --> 00:34:17.489 the patient. with your hand inside the vagina, 00:34:17.630 --> 00:34:19.750 elevating the head. You will ride down the hallway 00:34:19.750 --> 00:34:22.110 into the elevator, into the operating room, and 00:34:22.110 --> 00:34:24.130 you will not remove your hand until the surgeon 00:34:24.130 --> 00:34:26.449 makes the abdominal incision for a stat C -section 00:34:26.449 --> 00:34:28.969 and pulls the baby out from above. That is the 00:34:28.969 --> 00:34:31.369 definition of a mechanical intervention. I am 00:34:31.369 --> 00:34:34.289 the physical brace keeping the baby alive. Exactly. 00:34:34.869 --> 00:34:36.730 The mnemonic in the sources for the surrounding 00:34:36.730 --> 00:34:40.400 actions is fromi, fetal part elevated. Rapid 00:34:40.400 --> 00:34:43.800 response called. Reposition the client to a knee 00:34:43.800 --> 00:34:47.360 -chest position or extreme Trendelenburg. Let's 00:34:47.360 --> 00:34:49.599 explain knee -chest. Why that position? Because 00:34:49.599 --> 00:34:51.699 you want to use gravity to your advantage. If 00:34:51.699 --> 00:34:53.960 the client is on their hands and knees with their 00:34:53.960 --> 00:34:56.639 chest flat on the bed, their pelvis is the highest 00:34:56.639 --> 00:34:59.460 point of their body. Gravity will literally pull 00:34:59.460 --> 00:35:02.480 the heavy fetus back down toward the diaphragm 00:35:02.480 --> 00:35:04.500 and away from the pelvis, helping to relieve 00:35:04.500 --> 00:35:06.659 pressure on the cord. What about pushing the 00:35:06.659 --> 00:35:08.760 cord back inside? If it's hanging out, shouldn't 00:35:08.760 --> 00:35:10.860 I just tuck it back into the warm uterus? Never. 00:35:11.159 --> 00:35:13.480 That is a lethal exam trap. Never attempt to 00:35:13.480 --> 00:35:15.659 manually manipulate or push the cord back in. 00:35:15.719 --> 00:35:18.440 Why not? The umbilical vessels are highly sensitive. 00:35:18.739 --> 00:35:21.340 If you handle them, they will spasm. clamp shut, 00:35:21.559 --> 00:35:23.960 and completely cut off whatever remaining blood 00:35:23.960 --> 00:35:26.460 supply the fetus has. Just elevate the head, 00:35:26.739 --> 00:35:29.300 position the client, and call for help. OK, cord 00:35:29.300 --> 00:35:32.000 prolapse is terrifying. Let's look at the other 00:35:32.000 --> 00:35:34.659 mechanical nightmare, shoulder dystocia. Shoulder 00:35:34.659 --> 00:35:37.920 dystocia occurs during the actual delivery. The 00:35:37.920 --> 00:35:40.719 baby's head delivers out of the vagina, but the 00:35:40.719 --> 00:35:43.880 anterior shoulder gets physically wedged behind 00:35:43.880 --> 00:35:46.440 the maternal pubic symphysis, the front pelvic 00:35:46.440 --> 00:35:49.119 bone. The baby is trapped in the birth canal. 00:35:49.139 --> 00:35:51.559 Oh, man. They cannot breathe because their chest 00:35:51.559 --> 00:35:54.119 is compressed and the umbilical cord is compressed 00:35:54.119 --> 00:35:56.280 inside. The classic hallmark sign for this is 00:35:56.280 --> 00:35:59.219 the turtle sign, right? Yes. The head emerges 00:35:59.219 --> 00:36:01.619 with a push, but because the shoulders are stuck 00:36:01.619 --> 00:36:04.280 when the push ends, the head retracts tightly 00:36:04.280 --> 00:36:06.840 back against the maternal perineum. It looks 00:36:06.840 --> 00:36:08.980 exactly like a turtle pulling its head back into 00:36:08.980 --> 00:36:11.440 its shell. The sources mention a comprehensive 00:36:11.440 --> 00:36:17.250 mnemonic for the provider's actions. movement 00:36:17.250 --> 00:36:20.289 of the arm, position to hands and knees, episiotomy, 00:36:20.710 --> 00:36:23.289 elevate legs to knee chest, rotate the fetus. 00:36:23.469 --> 00:36:25.969 But let's focus on the nurse. What are my specific 00:36:25.969 --> 00:36:28.090 immediate physical interventions when the provider 00:36:28.090 --> 00:36:31.010 yells shoulder dystocia? The two immediate nursing 00:36:31.010 --> 00:36:33.690 interventions are the McRoberts maneuver and 00:36:33.690 --> 00:36:36.489 applying suprapubic pressure. For McRoberts, 00:36:36.730 --> 00:36:38.909 you and another nurse grab the client's legs, 00:36:39.409 --> 00:36:41.630 remove them from the stirrups, and sharply flex 00:36:41.630 --> 00:36:44.170 the client's thighs back tightly against their 00:36:44.170 --> 00:36:46.860 own abdomen. How does bending their legs back 00:36:46.860 --> 00:36:49.739 fix a stuck shoulder? It alters the biomechanics 00:36:49.739 --> 00:36:52.679 of the pelvis. By sharply flexing the legs, you 00:36:52.679 --> 00:36:55.039 flatten the sacral promontory in the back, and 00:36:55.039 --> 00:36:57.599 it rotates the symphysis pubis slightly upward 00:36:57.599 --> 00:37:01.219 in the front. This simple positional change effectively 00:37:01.219 --> 00:37:04.300 opens the pelvic angle and increases the diameter 00:37:04.300 --> 00:37:06.079 of the pelvic outlet by several millimeters, 00:37:06.579 --> 00:37:08.579 which is often just enough space to free the 00:37:08.579 --> 00:37:10.619 shoulder. Wow, just changing the angle of the 00:37:10.619 --> 00:37:14.909 bones. And what is the second action? Super pubic 00:37:14.909 --> 00:37:17.570 pressure. You literally stand on a stool next 00:37:17.570 --> 00:37:19.590 to the bed. You find the maternal pubic bone 00:37:19.590 --> 00:37:22.929 and you apply firm downward CPR style pressure 00:37:22.929 --> 00:37:25.010 with the heel of your hands right above the bone. 00:37:25.190 --> 00:37:27.670 What is that doing anatomically? You are trying 00:37:27.670 --> 00:37:30.469 to manually push the baby's stuck shoulder downward 00:37:30.469 --> 00:37:32.909 and forward, collapsing it slightly so it can 00:37:32.909 --> 00:37:35.610 slip under the bone. Which brings us to the top 00:37:35.610 --> 00:37:38.489 exam trap for shoulder dystocia. The trick question 00:37:38.489 --> 00:37:41.619 about fundal pressure. Yes. Test writers will 00:37:41.619 --> 00:37:43.820 try to trick you into applying fundal pressure. 00:37:44.380 --> 00:37:47.360 The fundus is the very top of the uterus. Imagine 00:37:47.360 --> 00:37:50.280 the mechanics. The baby's shoulder is jammed 00:37:50.280 --> 00:37:52.739 solidly against the front pelvic bone. If you 00:37:52.739 --> 00:37:55.019 push down from the top of the uterus, what happens? 00:37:55.300 --> 00:37:57.539 You just wedge the shoulder even harder into 00:37:57.539 --> 00:37:59.699 the bone, like trying to hammer a square peg 00:37:59.699 --> 00:38:02.139 into a round hole. You could fracture the baby's 00:38:02.139 --> 00:38:04.599 clavicle. Or worse, you could rupture the mother's 00:38:04.599 --> 00:38:07.840 uterus from the sheer force. Precisely. I correct 00:38:07.840 --> 00:38:10.210 this aggressively whenever I teach it. Never 00:38:10.210 --> 00:38:12.650 apply fundal pressure during a shoulder dystocia. 00:38:13.150 --> 00:38:15.610 It impacts the shoulder further. Always, always 00:38:15.610 --> 00:38:18.170 use suprapubic pressure. So those are the massive 00:38:18.170 --> 00:38:20.510 mechanical traps. But as we continue our progression, 00:38:20.909 --> 00:38:23.050 we have to talk about what happens when the mechanical 00:38:23.050 --> 00:38:26.110 forces of labor or trauma cause internal structural 00:38:26.110 --> 00:38:28.909 failure. We need to talk about the hidden bleeding 00:38:28.909 --> 00:38:31.789 emergencies, placental abruption versus uterine 00:38:31.789 --> 00:38:34.510 rupture. The ability to differentiate these two 00:38:34.510 --> 00:38:37.130 life -threatening events is a hallmark of elite 00:38:37.130 --> 00:38:40.159 clinical judgment. Placental abruption is when 00:38:40.159 --> 00:38:42.460 the placenta detaches from the inner uterine 00:38:42.460 --> 00:38:46.019 wall prematurely before the baby is born. Uterine 00:38:46.019 --> 00:38:48.460 rupture is when the actual muscular wall of the 00:38:48.460 --> 00:38:51.460 uterus tears entirely open. I compare the uterus 00:38:51.460 --> 00:38:54.219 to an inflated balloon. Abruption is like the 00:38:54.219 --> 00:38:56.559 inner lining of the balloon peeling away, pooling 00:38:56.559 --> 00:38:59.000 blood inside the balloon. Rupture is the balloon 00:38:59.000 --> 00:39:01.480 actually popping. That visual works perfectly. 00:39:02.079 --> 00:39:03.940 Let's look at the clinical picture of abruption. 00:39:04.460 --> 00:39:06.920 The hallmark symptom is sharp, sudden tearing 00:39:06.920 --> 00:39:10.309 abdominal pain. The bleeding can be overt, meaning 00:39:10.309 --> 00:39:12.570 you see dark red blood pouring from the vagina, 00:39:13.110 --> 00:39:15.730 but it can also be highly deceptive. It can be 00:39:15.730 --> 00:39:18.550 concealed. Concealed bleeding. If the edges of 00:39:18.550 --> 00:39:20.289 the placenta are still attached to the wall but 00:39:20.289 --> 00:39:22.730 the center is peeled away, it traps a massive 00:39:22.730 --> 00:39:25.150 pool of blood inside the uterus behind the placenta. 00:39:25.750 --> 00:39:28.010 You might not see a single drop of blood externally. 00:39:28.269 --> 00:39:30.710 But because it's bleeding massively inside that 00:39:30.710 --> 00:39:33.889 enclosed muscular space, the uterus reacts, right? 00:39:34.250 --> 00:39:37.599 Yes. Blood is highly irritating to the uterine 00:39:37.599 --> 00:39:41.059 muscle. The uterus clamps down hard and refuses 00:39:41.059 --> 00:39:44.400 to relax. The classic physical assessment finding 00:39:44.400 --> 00:39:48.219 is a rigid, board -like, titanic abdomen. It 00:39:48.219 --> 00:39:50.739 will be profoundly painful to the touch. What 00:39:50.739 --> 00:39:53.440 causes the placenta to just peel off like that? 00:39:53.659 --> 00:39:55.980 Usually it's extreme vasoconstriction or blunt 00:39:55.980 --> 00:39:59.199 force trauma. Cocaine use is a classic exam trigger 00:39:59.199 --> 00:40:01.260 for a corruption because it causes massive sudden 00:40:01.260 --> 00:40:03.719 spasms of the blood vessels. Severe maternal 00:40:03.719 --> 00:40:06.179 hypertension or a motor vehicle accident are 00:40:06.179 --> 00:40:09.159 also prime risk factors. Now, how does that clinical 00:40:09.159 --> 00:40:11.699 picture compare to a uterine rupture? With a 00:40:11.699 --> 00:40:14.000 rupture, the balloon pops. The client will report 00:40:14.000 --> 00:40:16.719 an acute tearing pain, often described as something 00:40:16.719 --> 00:40:19.840 giving way. But the unique, defining clinical 00:40:19.840 --> 00:40:21.900 sign here is a sudden loss of fetal station. 00:40:22.000 --> 00:40:24.400 Loss of station. The baby was at a plus one station, 00:40:24.679 --> 00:40:26.519 deep in the pelvis, moving down the birth canal. 00:40:26.730 --> 00:40:29.550 Suddenly, the uterus tears open, losing all its 00:40:29.550 --> 00:40:31.590 downward pressure, and the baby actually slips 00:40:31.590 --> 00:40:35.090 back up into the maternal abdominal cavity. You'll 00:40:35.090 --> 00:40:37.630 also often see referred pain to the chest or 00:40:37.630 --> 00:40:39.630 between the shoulder blades because the free 00:40:39.630 --> 00:40:41.409 -floating blood in the abdomen is irritating 00:40:41.409 --> 00:40:44.050 the diaphragm. The sources note that a VBAC, 00:40:44.329 --> 00:40:46.989 a vaginal birth after a previous cesarean, is 00:40:46.989 --> 00:40:50.309 the highest risk factor for a rupture. Yes, because 00:40:50.309 --> 00:40:53.010 the old surgical star on the uterus is a line 00:40:53.010 --> 00:40:55.699 of structural weakness. Under the intense pressure 00:40:55.699 --> 00:40:58.599 of labor contractions, that scar can give way. 00:40:59.159 --> 00:41:01.340 So what are our priority nursing actions for 00:41:01.340 --> 00:41:03.159 both of these profound bleeding emergencies? 00:41:03.820 --> 00:41:06.400 Obviously we are calling a rapid response and 00:41:06.400 --> 00:41:08.920 prepping for a stat C -section, targeting delivery 00:41:08.920 --> 00:41:12.219 in under 30 minutes. But what are we doing hemodynamically? 00:41:12.320 --> 00:41:14.320 You're managing a hemorrhagic shock protocol. 00:41:14.739 --> 00:41:17.219 You must establish two large bore IVs immediately. 00:41:17.420 --> 00:41:20.199 We need at least an 18 gauge catheter, preferably 00:41:20.199 --> 00:41:22.460 a 16 gauge. Why do they have to be so large? 00:41:22.820 --> 00:41:25.039 Fluid dynamics. You cannot push viscous packed 00:41:25.039 --> 00:41:27.699 red blood cells rapidly through a tiny 22 gauge 00:41:27.699 --> 00:41:30.559 hand of V. The cells will hemolyze and the flow 00:41:30.559 --> 00:41:33.460 rate is too slow. You need a large pipe to slam 00:41:33.460 --> 00:41:35.340 aggressive fluid and blood volume replacement 00:41:35.340 --> 00:41:37.480 into the maternal circulation before her organs 00:41:37.480 --> 00:41:39.820 shut down from lack of perfusion. You will also 00:41:39.820 --> 00:41:42.159 anticipate sending a Klyhauer -Betke test to 00:41:42.159 --> 00:41:44.960 the lab. Let's explain the Klyhauer -Betke test. 00:41:45.579 --> 00:41:48.159 It detects if fetal red blood cells have crossed 00:41:48.159 --> 00:41:50.400 the damaged placental barrier and entered the 00:41:50.400 --> 00:41:53.639 maternal bloodstream. Exactly. This is crucial 00:41:53.639 --> 00:41:55.920 if the mother has an Rh -negative blood type. 00:41:56.659 --> 00:41:59.480 If fetal blood has mixed with hers during this 00:41:59.480 --> 00:42:02.039 traumatic tearing event, her immune system will 00:42:02.039 --> 00:42:04.480 recognize the fetal blood as a foreign invader 00:42:04.480 --> 00:42:07.800 and build antibodies against it. This will destroy 00:42:07.800 --> 00:42:10.460 future pregnancies. So the test tells us how 00:42:10.460 --> 00:42:13.659 much ROGAM to give. Yes. The Clara Beckett test 00:42:13.659 --> 00:42:16.079 quantifies exactly how much fetal blood is crossed 00:42:16.079 --> 00:42:18.659 over, which dictates exactly how many vials of 00:42:18.659 --> 00:42:21.079 ROGAM the nurse needs to administer to suppress 00:42:21.079 --> 00:42:23.650 that immune response. There is a classic exam 00:42:23.650 --> 00:42:25.969 trap here regarding bleeding that we must clarify. 00:42:26.550 --> 00:42:28.750 Distinguishing placental abruption from placenta 00:42:28.750 --> 00:42:31.429 previa. They both cause massive third trimester 00:42:31.429 --> 00:42:33.849 bleeding. How do we keep them straight? It all 00:42:33.849 --> 00:42:35.730 comes down to the presence or absence of pain. 00:42:35.949 --> 00:42:39.250 Placental abruption is deeply, intensely painful 00:42:39.250 --> 00:42:42.150 with that rigid, board -like abdomen and dark 00:42:42.150 --> 00:42:44.809 red blood. Placenta previa, where the placenta 00:42:44.809 --> 00:42:47.329 has implanted low in the uterus, completely covering 00:42:47.329 --> 00:42:50.210 the cervical opening, is classically characterized 00:42:50.210 --> 00:42:53.570 by sudden, painless, bright red vaginal bleeding. 00:42:54.050 --> 00:42:58.320 The abdomen remains soft and non -tender. dark 00:42:58.320 --> 00:43:00.800 blood, rigid abdomen, previa equals painless, 00:43:00.960 --> 00:43:03.619 bright red blood, soft abdomen. That is a rock 00:43:03.619 --> 00:43:06.719 solid pattern to memorize. So, moving forward, 00:43:07.139 --> 00:43:09.579 not all complications result in a dramatic rush 00:43:09.579 --> 00:43:12.059 to the operating room for a C -section. Sometimes 00:43:12.059 --> 00:43:13.840 we have to manage the mess right there in the 00:43:13.840 --> 00:43:17.139 birth canal. Let's discuss meconium, malpresentation, 00:43:17.280 --> 00:43:19.519 and operative delivery. Let's start with meconium. 00:43:19.679 --> 00:43:22.360 We touched on this earlier. When a fetus experiences 00:43:22.360 --> 00:43:25.460 significant stress or hypoxia in utero, their 00:43:25.460 --> 00:43:28.159 vagus nerve is stimulated. This causes their 00:43:28.159 --> 00:43:30.460 anal sphincter to relax and they pass their first 00:43:30.460 --> 00:43:33.119 bowel movement, meconium, into the amniotic fluid. 00:43:33.219 --> 00:43:35.239 Which happens a lot when they are overdue. It's 00:43:35.239 --> 00:43:38.139 highly common in post -term babies past 41 weeks 00:43:38.139 --> 00:43:40.940 as the placenta naturally begins to degrade and 00:43:40.940 --> 00:43:43.599 oxygen levels drop. The fluid goes from clear 00:43:43.599 --> 00:43:46.659 to looking like thick green pea soup. And the 00:43:46.659 --> 00:43:49.239 major danger here is meconium aspiration syndrome. 00:43:49.599 --> 00:43:52.579 If the baby takes a deep gasp while still inside 00:43:52.579 --> 00:43:55.960 or immediately upon birth, they inhale this thick, 00:43:56.199 --> 00:43:59.059 sticky tar deep into their lungs. It blocks the 00:43:59.059 --> 00:44:01.440 airways and causes severe chemical pneumonitis. 00:44:01.619 --> 00:44:04.440 Exactly. So what is the priority nursing action 00:44:04.440 --> 00:44:06.699 during labor if the water breaks and it's thick 00:44:06.699 --> 00:44:09.590 with meconium? We try to dilute the soup. The 00:44:09.590 --> 00:44:11.829 provider might order an amnio -infusion. The 00:44:11.829 --> 00:44:13.809 nurse assists in placing an intra -water and 00:44:13.809 --> 00:44:16.190 pressure catheter past the baby's head. And we 00:44:16.190 --> 00:44:19.090 continuously flush sterile, warmed, normal saline 00:44:19.090 --> 00:44:21.230 into the uterus. Which washes it out. It thins 00:44:21.230 --> 00:44:23.869 out the meconium so it's less toxic if aspirated. 00:44:24.369 --> 00:44:26.949 And crucially, we absolutely must alert the NICU 00:44:26.949 --> 00:44:29.369 team to be physically present in the room for 00:44:29.369 --> 00:44:31.690 the delivery. Perfect. Now I want to highlight 00:44:31.690 --> 00:44:34.150 a major shift in evidence -based practice regarding 00:44:34.150 --> 00:44:36.940 meconium at the exact moment of birth. It is 00:44:36.940 --> 00:44:39.119 a highly testable area because the old rules 00:44:39.119 --> 00:44:41.760 have changed. Right. It used to be that if there 00:44:41.760 --> 00:44:43.920 was meconium fluid, the moment the baby's head 00:44:43.920 --> 00:44:46.559 delivered, before the body even came out, the 00:44:46.559 --> 00:44:48.880 provider would stop and aggressively deep suction 00:44:48.880 --> 00:44:51.059 the baby's mouth and trachea to clear it out. 00:44:51.440 --> 00:44:54.260 But doing that is a track now. Correct. We no 00:44:54.260 --> 00:44:56.460 longer perform routine intrapartum suctioning 00:44:56.460 --> 00:44:59.360 for meconium. The current evidence -based protocol 00:44:59.360 --> 00:45:01.800 dictates that if a baby is born through meconium 00:45:01.800 --> 00:45:04.460 and comes out vigorous, meaning they are crying 00:45:04.460 --> 00:45:07.139 lustily, have a heart rate over 100, and have 00:45:07.139 --> 00:45:10.519 good muscle tone, you do not perform deep tracheal 00:45:10.519 --> 00:45:12.719 suctioning. You just wipe their face and provide 00:45:12.719 --> 00:45:15.000 routine care. Why did we stop? Wasn't it helpful 00:45:15.000 --> 00:45:17.639 to get the tar out? Because aggressively jamming 00:45:17.639 --> 00:45:19.900 a suction catheter down the throat of a vigorous 00:45:19.900 --> 00:45:22.980 crying baby stimulates their vagus nerve. It 00:45:22.980 --> 00:45:26.010 can cause profound reflex bradycardia, their 00:45:26.010 --> 00:45:27.730 heart rate plummets. We were actually causing 00:45:27.730 --> 00:45:29.969 more harm than good. You only intervene with 00:45:29.969 --> 00:45:32.389 deep suctioning and intubation. If the newborn 00:45:32.389 --> 00:45:35.210 is depressed, floppy, not breathing with a low 00:45:35.210 --> 00:45:38.030 heart rate. That is a critical nuance for clinical 00:45:38.030 --> 00:45:40.750 judgment. Treat the patient, not just the fluid. 00:45:41.110 --> 00:45:43.909 Okay, what about malpresentation? Specifically, 00:45:44.309 --> 00:45:46.880 a breech baby. The biomechanically safest way 00:45:46.880 --> 00:45:49.360 for a baby to navigate the pelvis is head first, 00:45:49.780 --> 00:45:52.119 with the chin tucked tightly to the chest. If 00:45:52.119 --> 00:45:53.960 there are a breach coming down buttocks or feet 00:45:53.960 --> 00:45:56.360 first, the largest, hardest part of the body, 00:45:56.579 --> 00:45:59.960 the head, is delivered last. Which is super dangerous. 00:46:00.119 --> 00:46:01.980 This poses a massive risk for the head getting 00:46:01.980 --> 00:46:05.090 trapped or the umbilical cord prolapsing. Therefore, 00:46:05.090 --> 00:46:07.570 before labor begins, a provider might attempt 00:46:07.570 --> 00:46:11.090 an external cephalic version, or ECV. This sounds 00:46:11.090 --> 00:46:13.329 somewhat barbaric when you describe it. They 00:46:13.329 --> 00:46:15.789 put their hands on the outside of Lather's abdomen, 00:46:16.250 --> 00:46:19.429 grab the baby through the uterine wall, and literally 00:46:19.429 --> 00:46:22.329 try to manually somersault the baby into a head 00:46:22.329 --> 00:46:24.469 -down position. It is intense, and it carries 00:46:24.469 --> 00:46:27.250 significant risks. As the nurse managing this 00:46:27.250 --> 00:46:29.650 procedure, you must know that an ECV requires 00:46:29.650 --> 00:46:32.110 complete readiness for a stat C -section. Just 00:46:32.110 --> 00:46:34.630 in case things go south. While the provider is 00:46:34.630 --> 00:46:36.789 physically manipulating and dragging the fetus 00:46:36.789 --> 00:46:39.630 around inside the uterus, they can easily cause 00:46:39.630 --> 00:46:42.590 a placental abruption, or they can entangle and 00:46:42.590 --> 00:46:45.710 compress the umbilical cord. You are continuously 00:46:45.710 --> 00:46:48.409 monitoring the fetal heart rate, and if severe 00:46:48.409 --> 00:46:51.130 bradycardia occurs and doesn't dissolve, you 00:46:51.130 --> 00:46:53.289 are rolling the bed straight down the hall to 00:46:53.289 --> 00:46:55.989 the OR. Okay, the last mechanical intervention 00:46:55.989 --> 00:46:59.079 to discuss. Operative vaginal birth. This is 00:46:59.079 --> 00:47:02.159 when the provider uses forceps or a vacuum extractor 00:47:02.159 --> 00:47:04.360 applied to the baby's head to physically pull 00:47:04.360 --> 00:47:06.780 them out. The indications for this are usually 00:47:06.780 --> 00:47:09.699 a prolonged second stage of labor. The client 00:47:09.699 --> 00:47:11.679 has been pushing for three hours and is completely 00:47:11.679 --> 00:47:14.860 physically exhausted or there is a sudden non 00:47:14.860 --> 00:47:17.380 -reassuring fetal heart rate drop and the baby 00:47:17.380 --> 00:47:19.659 is low enough in the pelvis that a vacuum extraction 00:47:19.659 --> 00:47:22.039 is actually faster than prepping for a c -section. 00:47:22.400 --> 00:47:24.739 The priority nursing action here that stood out 00:47:24.739 --> 00:47:26.679 to me in the sources seems almost too simple 00:47:26.679 --> 00:47:30.210 but it is critical. Empty the bladder. Yes. It 00:47:30.210 --> 00:47:32.750 is a mechanical necessity. If you are inserting 00:47:32.750 --> 00:47:36.190 large metal spoons forceps or a vacuum cup into 00:47:36.190 --> 00:47:39.250 the vaginal canal to forcefully drag a baby past 00:47:39.250 --> 00:47:42.409 the pubic bone, a full maternal bladder sits 00:47:42.409 --> 00:47:45.369 directly in the crossfire. A full bladder physically 00:47:45.369 --> 00:47:48.110 blocks the baby's descent and it is at incredibly 00:47:48.110 --> 00:47:50.130 high risk for being crushed and ruptured by the 00:47:50.130 --> 00:47:51.889 instruments. You definitely don't want a ruptured 00:47:51.889 --> 00:47:54.050 bladder. You must insert a straight catheter 00:47:54.050 --> 00:47:56.289 to empty the bladder before the procedure begins. 00:47:56.980 --> 00:47:59.159 Furthermore, you must verify that the cervix 00:47:59.159 --> 00:48:02.199 is 100 % dilated to 10 centimeters, the membranes 00:48:02.199 --> 00:48:04.340 are ruptured, and the fetal station is low, at 00:48:04.340 --> 00:48:06.960 least a plus two, before forceps or a vacuum 00:48:06.960 --> 00:48:09.699 are ever applied. And postpartum, after a vacuum 00:48:09.699 --> 00:48:12.360 delivery, the nurse must meticulously monitor 00:48:12.360 --> 00:48:14.719 the newborn for a cephalohematoma. Let's connect 00:48:14.719 --> 00:48:17.340 the dogs on why. What is a cephalohematoma? It 00:48:17.340 --> 00:48:19.679 is a collection of blood pooling under the scalp. 00:48:19.840 --> 00:48:22.679 specifically caused by the intense trauma and 00:48:22.679 --> 00:48:24.699 suction of the vacuum cup tearing tiny blood 00:48:24.699 --> 00:48:27.280 vessels. And the secondary complication is what 00:48:27.280 --> 00:48:30.280 we really care about. As that trapped pool of 00:48:30.280 --> 00:48:32.219 red blood cells begins to break down over the 00:48:32.219 --> 00:48:34.639 next few days, it releases massive amounts of 00:48:34.639 --> 00:48:37.360 bilirubin into the newborn system. Their immature 00:48:37.360 --> 00:48:40.019 liver can't process it fast enough, leading to 00:48:40.019 --> 00:48:49.730 severe hyper bilirubinemia or jaundice. natal 00:48:49.730 --> 00:48:52.250 complication. So we've spent this entire time 00:48:52.250 --> 00:48:55.110 talking about amniote infusions, vacuums, rapid 00:48:55.110 --> 00:48:57.469 response teams, dropping heart rates, and stat 00:48:57.469 --> 00:49:00.789 C -sections. But in the chaos of all these highly 00:49:00.789 --> 00:49:03.130 clinical, highly aggressive interventions, there 00:49:03.130 --> 00:49:05.510 is a human being at the center of the bed experiencing 00:49:05.510 --> 00:49:07.590 what is likely the most terrifying traumatic 00:49:07.590 --> 00:49:10.369 moment of their life. We cannot ignore the psychological 00:49:10.369 --> 00:49:12.889 reality of obstetrics. Which brings us to the 00:49:12.889 --> 00:49:16.369 human element. Grief, loss, and psychosocial 00:49:16.369 --> 00:49:19.010 support. This is arguably the most profoundly 00:49:19.010 --> 00:49:21.750 important aspect of nursing, and yet it is often 00:49:21.750 --> 00:49:23.909 the hardest to teach and the most uncomfortable 00:49:23.909 --> 00:49:27.530 to test. The high -yield core here is that obstetrical 00:49:27.530 --> 00:49:30.210 emergencies utterly destroy the client's perceived 00:49:30.210 --> 00:49:34.070 ideal birth plan. Whether it results in severe 00:49:34.070 --> 00:49:37.769 maternal physical trauma, postpartum PTSD, or 00:49:37.769 --> 00:49:40.869 the unthinkable tragedy of fetal loss, the psychological 00:49:40.869 --> 00:49:43.630 impact is shattering. The sources mention a specific 00:49:43.630 --> 00:49:47.269 term, disenfranchised grief. When a miscarriage 00:49:47.269 --> 00:49:50.190 or stillbirth occurs, society often inadvertently 00:49:50.190 --> 00:49:52.449 minimizes it. People say things like, well, at 00:49:52.449 --> 00:49:54.449 least you're only 20 weeks, or you didn't really 00:49:54.449 --> 00:49:56.590 know the baby yet. But to that family, they didn't 00:49:56.590 --> 00:49:59.170 just lose a fetus, they lost their entire envisioned 00:49:59.170 --> 00:50:01.570 future. They lost the first day of school, the 00:50:01.570 --> 00:50:03.789 graduations, the whole identity of being that 00:50:03.789 --> 00:50:06.269 child's parent. Why does understanding this matter 00:50:06.269 --> 00:50:08.630 so much for the nurse at the bedside? Because 00:50:08.630 --> 00:50:10.559 while the clinical interventions... The large 00:50:10.559 --> 00:50:12.840 bore IVs, the emergency meds, the chest compressions 00:50:12.840 --> 00:50:15.400 save the physical body. The nurse's communication, 00:50:15.579 --> 00:50:17.739 empathy, and presence are what saved the patient's 00:50:17.739 --> 00:50:20.019 mind. I'll be honest. When I read the protocol 00:50:20.019 --> 00:50:22.619 for fetal loss in the sources, it felt overwhelming. 00:50:22.920 --> 00:50:25.480 It's essentially the, I didn't know what to say, 00:50:25.860 --> 00:50:28.340 protocol. And that is exactly how I would feel 00:50:28.340 --> 00:50:30.159 standing in that room. I wouldn't want to open 00:50:30.159 --> 00:50:32.139 my mouth for fear of making the worst day of 00:50:32.139 --> 00:50:35.739 their life even worse. That exact fear of making 00:50:35.739 --> 00:50:38.769 it worse. is the number one reason nurses physically 00:50:38.769 --> 00:50:41.230 and emotionally withdraw from grieving patients. 00:50:42.010 --> 00:50:44.969 We go in, check the vital signs in silence, and 00:50:44.969 --> 00:50:47.869 leave the room as fast as possible. But the evidence 00:50:47.869 --> 00:50:50.489 tells us that clients and families usually desperately 00:50:50.489 --> 00:50:52.730 want to talk about their baby and their experience. 00:50:53.250 --> 00:50:56.070 If you do not know what to say, your priority 00:50:56.070 --> 00:50:58.690 nursing intervention is to provide presence. 00:50:59.269 --> 00:51:02.289 What does providing presence actually look like? 00:51:02.389 --> 00:51:04.690 It means you actively listen. You pull up a chair. 00:51:04.909 --> 00:51:07.409 sit down at eye level, and you become comfortable 00:51:07.409 --> 00:51:10.610 with heavy agonizing silence. You explicitly 00:51:10.610 --> 00:51:12.750 acknowledge their parenthood. You call them mom 00:51:12.750 --> 00:51:15.329 or dad. You ask, did you have a name chosen for 00:51:15.329 --> 00:51:17.849 your baby? And then you use that name. You treat 00:51:17.849 --> 00:51:19.889 the baby with the exact same dignity and reverence 00:51:19.889 --> 00:51:22.460 you would a living patient. It's incredibly hard 00:51:22.460 --> 00:51:24.880 because medical training literally wires you 00:51:24.880 --> 00:51:27.579 to be a fixer. If the blood pressure is low, 00:51:27.739 --> 00:51:29.619 you push fluids to fix it. If the heart rate 00:51:29.619 --> 00:51:32.179 is dropping, you reposition to fix it. So when 00:51:32.179 --> 00:51:34.679 a tragedy happens that is absolute and permanent, 00:51:35.119 --> 00:51:36.900 standing there in silence without a fix feels 00:51:36.900 --> 00:51:39.539 like a massive professional failure. But I need 00:51:39.539 --> 00:51:42.199 every future nurse listening to reframe that 00:51:42.199 --> 00:51:45.739 mentality entirely. Providing intentional presence 00:51:45.739 --> 00:51:49.460 is not a passive failure. It is an active, demanding, 00:51:49.780 --> 00:51:52.280 evidence -based nursing intervention. You hold 00:51:52.280 --> 00:51:55.159 the space for their grief, you do not make excuses 00:51:55.159 --> 00:51:57.900 for the medical team, and most importantly, you 00:51:57.900 --> 00:52:00.539 absolutely do not offer toxic positivity. You 00:52:00.539 --> 00:52:02.920 mean the well -intentioned but horrific cliches, 00:52:03.099 --> 00:52:05.179 like everything happens for a reason, or God 00:52:05.179 --> 00:52:07.139 needed another angel, or you're young, you can 00:52:07.139 --> 00:52:09.679 always have another one. Yes. Those statements 00:52:09.679 --> 00:52:12.119 are incredibly damaging. They invalidate the 00:52:12.119 --> 00:52:14.260 absolute reality of the patient's current grief. 00:52:14.739 --> 00:52:17.119 You provide clear, honest information about what 00:52:17.119 --> 00:52:19.920 is happening, and you simply validate their devastating 00:52:19.920 --> 00:52:22.940 reality. I am so sorry this is happening. I am 00:52:22.940 --> 00:52:26.420 here with you. That is the intervention. Holding 00:52:26.420 --> 00:52:29.420 the space. It's a clinical skill just as critical 00:52:29.420 --> 00:52:31.579 as knowing how to push your butyl in or read 00:52:31.579 --> 00:52:34.440 a fetal monitor strip. It truly is. It is what 00:52:34.440 --> 00:52:37.119 separates a competent technician from a true 00:52:37.119 --> 00:52:39.650 nurse. Well, we have covered a massive amount 00:52:39.650 --> 00:52:42.230 of clinical ground today. We navigated the pharmacology 00:52:42.230 --> 00:52:44.670 of early warning signs, we broke down the physiology 00:52:44.670 --> 00:52:47.150 of fetal monitoring, we drilled the mechanics 00:52:47.150 --> 00:52:50.130 of the most intense bleeding and track baby emergencies, 00:52:50.550 --> 00:52:53.690 and we anchored it all in the profound psychosocial 00:52:53.690 --> 00:52:56.210 duty we owe our patients. Let's distill everything 00:52:56.210 --> 00:52:58.530 we've discussed into the absolute most critical 00:52:58.530 --> 00:53:01.670 takeaways. If you only remember five things from 00:53:01.670 --> 00:53:04.010 this entire deep dive to take into your exam 00:53:04.010 --> 00:53:06.289 and your clinical practice, make it these five 00:53:06.289 --> 00:53:08.949 concepts. There we go. Number one. Number one, 00:53:09.289 --> 00:53:11.989 magnesium sulfate toxicity. You are administering 00:53:11.989 --> 00:53:15.070 a CNS depressant. You must watch for absent deep 00:53:15.070 --> 00:53:17.610 tendon reflexes, respiratory depression below 00:53:17.610 --> 00:53:21.110 12, and urine output below 30. If you see these 00:53:21.110 --> 00:53:23.610 signs, you stop the drip immediately and administer 00:53:23.610 --> 00:53:26.130 the antidote, calcium gluconate. Number two. 00:53:26.309 --> 00:53:29.250 Number two, intruder and resuscitation for non 00:53:29.250 --> 00:53:32.230 -reassuring fetal heart rates, specifically late 00:53:32.230 --> 00:53:35.090 decelerations. Remember, Fix the plumbing before 00:53:35.090 --> 00:53:38.210 you supply the gas. Stop the oxytocin, reposition 00:53:38.210 --> 00:53:40.769 the client to offload the vena cava, increase 00:53:40.769 --> 00:53:43.590 IV fluids to boost placental perfusion, and only 00:53:43.590 --> 00:53:46.469 then apply oxygen if needed. Number three. Number 00:53:46.469 --> 00:53:49.739 three. Cord prolapse. The cord washes out before 00:53:49.739 --> 00:53:52.480 the fetal head, cutting off circulation. Never 00:53:52.480 --> 00:53:55.119 attempt to push the cord back in. Use a sterile 00:53:55.119 --> 00:53:57.699 gloved hand to elevate the presenting fetal part 00:53:57.699 --> 00:53:59.900 off a cord. Reposition the client knee chest 00:53:59.900 --> 00:54:02.219 to utilize gravity and keep your hand in place 00:54:02.219 --> 00:54:04.679 all the way to the operating room. Number four. 00:54:05.539 --> 00:54:08.639 Shoulder dystocia. The head delivers, but the 00:54:08.639 --> 00:54:11.099 anterior shoulder is impacted behind the pubic 00:54:11.099 --> 00:54:13.900 bone. Look at the turtle sign. Immediately initiate 00:54:13.900 --> 00:54:15.840 the McRoberts maneuver by flexing the maternal 00:54:15.840 --> 00:54:18.539 knees sharply back to the abdomen and apply downward 00:54:18.539 --> 00:54:20.340 suprapubic pressure to collapse the shoulder. 00:54:20.860 --> 00:54:23.099 Never, ever apply fundal pressure as it will 00:54:23.099 --> 00:54:25.480 wedge the baby further. And number five. Number 00:54:25.480 --> 00:54:28.440 five, differentiating placental abruption from 00:54:28.440 --> 00:54:31.800 previa. Placental abruption is a premature tearing 00:54:31.800 --> 00:54:34.559 away of the placenta. It is characterized by 00:54:34.559 --> 00:54:37.960 deeply painful dark red bleeding and a rigid 00:54:37.960 --> 00:54:41.650 board -like abdomen. Establish two large bore 00:54:41.650 --> 00:54:45.690 IVs immediately for massive fluid and blood resuscitation. 00:54:46.269 --> 00:54:49.809 Previa. by contrast, is painless and bright red. 00:54:50.010 --> 00:54:52.130 I can guarantee those five points alone are going 00:54:52.130 --> 00:54:54.429 to save you on test day. And much more importantly, 00:54:54.630 --> 00:54:57.030 internalizing the why behind them is going to 00:54:57.030 --> 00:54:59.130 make you a fundamentally safe nurse when the 00:54:59.130 --> 00:55:02.090 alarms start ringing at 3 a .m. That is the ultimate 00:55:02.090 --> 00:55:04.510 goal. To leave you with a deeper philosophical 00:55:04.510 --> 00:55:06.949 takeaway rooted in the text we've been analyzing, 00:55:07.510 --> 00:55:09.230 we started this conversation by acknowledging 00:55:09.230 --> 00:55:11.849 that obstetrics isn't like clean binary engineering. 00:55:12.010 --> 00:55:14.530 It is messy, rapid and unpredictable. We spent 00:55:14.530 --> 00:55:16.469 the better part of an hour learning how to execute 00:55:16.469 --> 00:55:19.050 a stat C -section in under 30 minutes, how to 00:55:19.050 --> 00:55:21.889 deploy rapid response teams, and how to use aggressive 00:55:21.889 --> 00:55:24.409 emergency protocols to snatch life from the jaws 00:55:24.409 --> 00:55:27.070 of tragedy. But the source material explicitly 00:55:27.070 --> 00:55:29.489 highlights the invisible toll of our clinical 00:55:29.489 --> 00:55:33.039 efficiency. The sudden violent loss of the mother's 00:55:33.039 --> 00:55:35.860 perceived ideal birth plan and the profound trauma 00:55:35.860 --> 00:55:38.900 that follows. As a future nurse, how do you balance 00:55:38.900 --> 00:55:41.340 the aggressive mechanical rapid -fire urgency 00:55:41.340 --> 00:55:43.980 required to save a physical life with the gentle 00:55:43.980 --> 00:55:46.239 intentional patient presence required to protect 00:55:46.239 --> 00:55:48.360 the psychological one? It is the hardest balancing 00:55:48.360 --> 00:55:51.000 act in all of obstetrics and mastering it is 00:55:51.000 --> 00:55:52.300 the true mark of an elite nurse.
