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 --> 00:00:30.699 room. Pulse check! No pulse. And her blood pressure 00:00:30.699 --> 00:00:36.460 is off. 45 minutes of CPR and no return of circulation. 00:00:41.340 --> 00:00:44.500 Picture this. You just walked onto the labor 00:00:44.500 --> 00:00:47.439 and delivery unit for your very first clinical 00:00:47.439 --> 00:00:49.939 shift. Oh, that first day is always wild. Right. 00:00:50.119 --> 00:00:52.859 So you step into room three, and the patient 00:00:52.859 --> 00:00:55.820 is 39 weeks pregnant, gripping the bed rails. 00:00:56.359 --> 00:01:00.060 And her eyes are just wide with panic. Absolutely 00:01:00.060 --> 00:01:02.539 terrifying for her, yeah. And the fetal monitor 00:01:02.539 --> 00:01:04.379 next to her, which have been chiming along with 00:01:04.379 --> 00:01:08.599 this really reassuring rhythmic heartbeat, suddenly 00:01:08.599 --> 00:01:12.409 drops its pitch. It's sounding this long, sustained, 00:01:13.349 --> 00:01:16.450 just terrifyingly slow tone. The dreaded bradycardia 00:01:16.450 --> 00:01:18.810 alarm. Exactly. The jagged line on the screen 00:01:18.810 --> 00:01:21.290 just falls into a deep valley and it's completely 00:01:21.290 --> 00:01:23.969 not coming back up. And then your preceptor turns 00:01:23.969 --> 00:01:25.890 to you, the nursing student, and says, well, 00:01:25.989 --> 00:01:28.269 what is happening and what exactly do we do right 00:01:28.269 --> 00:01:31.099 now? Yeah. That is the ultimate trial by fire 00:01:31.099 --> 00:01:33.400 because in that specific moment, you really don't 00:01:33.400 --> 00:01:35.920 have the luxury of like pulling out a thousand 00:01:35.920 --> 00:01:38.180 page textbook to look up the pathophysiology 00:01:38.180 --> 00:01:40.659 of fetal bradycardia. No, not at all. You literally 00:01:40.659 --> 00:01:43.540 have seconds. Right. And honestly, the sheer 00:01:43.540 --> 00:01:46.040 volume of information thrown at you in nursing 00:01:46.040 --> 00:01:50.040 school regarding maternal newborn and women's 00:01:50.040 --> 00:01:53.569 health is just it's staggering. It really is. 00:01:53.629 --> 00:01:55.510 I mean, you're expected to understand two patients 00:01:55.510 --> 00:01:57.549 simultaneously. One of whom you can't even see. 00:01:57.909 --> 00:02:01.269 Exactly. In a situation where, you know, normal 00:02:01.269 --> 00:02:03.950 physiology can pivot into a catastrophic emergency 00:02:03.950 --> 00:02:06.129 in less than three minutes. Which is why the 00:02:06.129 --> 00:02:08.629 traditional approach of, like, reading a textbook 00:02:08.629 --> 00:02:11.330 from cover to cover just doesn't work for clinical 00:02:11.330 --> 00:02:14.110 readiness. No, it fails every time. To be a safe, 00:02:14.330 --> 00:02:16.090 competent nurse, you have to filter the noise. 00:02:16.409 --> 00:02:18.949 So if you are tuning in right now, consider us 00:02:18.949 --> 00:02:21.669 your personal clinical mentors and study coaches. 00:02:21.909 --> 00:02:24.469 for the next hour because we are taking all those 00:02:24.469 --> 00:02:27.150 massive obstetric sources, all the care plans, 00:02:27.289 --> 00:02:29.569 the clinical guidelines, and we are aggressively 00:02:29.569 --> 00:02:31.949 applying the Pareto principle. That's the 80 00:02:31.949 --> 00:02:34.409 -20 rule. Right. We're hunting for that 20 % 00:02:34.409 --> 00:02:37.250 of crucial concepts, the physiological patterns, 00:02:37.469 --> 00:02:39.789 and those safety critical red flags that will, 00:02:39.789 --> 00:02:42.650 frankly, generate 80 % of your exam points. And 00:02:42.650 --> 00:02:45.009 more importantly, keep your future patients alive. 00:02:45.409 --> 00:02:48.189 Exactly. So what's our mission today? Well, we 00:02:48.189 --> 00:02:50.889 are going to prioritize high -yield material, 00:02:51.430 --> 00:02:54.050 but we aren't going to just give you a dry list 00:02:54.050 --> 00:02:56.969 of facts to memorize, because rote memorization 00:02:56.969 --> 00:03:00.069 completely fails under pressure. Oh, 100%. You 00:03:00.069 --> 00:03:03.210 just blank. You do. If you don't understand the 00:03:03.210 --> 00:03:06.139 why behind an intervention... Your mind goes 00:03:06.139 --> 00:03:08.860 blank when the alarms start sounding. So we're 00:03:08.860 --> 00:03:11.060 going to break down the mechanics, the fluid 00:03:11.060 --> 00:03:13.919 dynamics, and the raw biology of labor so that 00:03:13.919 --> 00:03:16.240 your clinical judgment just becomes instinctive. 00:03:16.500 --> 00:03:19.659 I love that. No jargon without explanation, no 00:03:19.659 --> 00:03:23.419 academic fluff, just a deep dive into how to 00:03:23.419 --> 00:03:26.199 think like an elite OB nurse. Ready to jump in. 00:03:26.240 --> 00:03:28.060 Let's do it. Let's back out of that terrifying 00:03:28.060 --> 00:03:29.960 room for a second. Because before we can rush 00:03:29.960 --> 00:03:33.439 in and save the day during an emergency, we have 00:03:33.439 --> 00:03:35.000 to know what a normal day is like. supposed to 00:03:35.000 --> 00:03:37.340 look like. You have to know baseline to spot 00:03:37.340 --> 00:03:39.560 the abnormal. Right. I always think of this like 00:03:39.560 --> 00:03:41.520 flying a commercial jet. You would just throw 00:03:41.520 --> 00:03:43.800 a student pilot into a nosedive simulation on 00:03:43.800 --> 00:03:45.900 day one. First you teach them how to read the 00:03:45.900 --> 00:03:47.539 dashboard while the plane is safely cruising. 00:03:47.789 --> 00:03:51.069 That's a really perfect analogy. Because in obstetrics, 00:03:51.169 --> 00:03:54.110 when a patient rolls into triage, your dashboard 00:03:54.110 --> 00:03:57.389 consists of mapping out three interacting forces. 00:03:58.090 --> 00:03:59.889 They're traditionally called the three P's, which 00:03:59.889 --> 00:04:02.990 are power, passenger, and passage. The three 00:04:02.990 --> 00:04:06.030 P's. Right. If you don't evaluate how these three 00:04:06.030 --> 00:04:08.949 are interacting, you are flying blind. OK, let's 00:04:08.949 --> 00:04:10.750 break down that dashboard for everyone listening. 00:04:10.789 --> 00:04:13.449 Yeah. Power sounds obvious, right? Yeah. Like, 00:04:13.449 --> 00:04:16.350 that's the uterine contractions, the engine pushing 00:04:16.350 --> 00:04:19.660 the plane. It's the primary force of labor, but 00:04:19.660 --> 00:04:22.579 it's not just about... having contractions, it's 00:04:22.579 --> 00:04:24.600 about their quality. What do you mean by quality? 00:04:25.000 --> 00:04:27.519 Well, we have to assess whether they are strong 00:04:27.519 --> 00:04:30.120 enough, frequent enough, and of sufficient duration 00:04:30.120 --> 00:04:32.819 to actually do the panicle work. The work of 00:04:32.819 --> 00:04:35.339 opening the cervix? Exactly. Opening the cervix 00:04:35.339 --> 00:04:37.779 and physically moving the baby down. Then you 00:04:37.779 --> 00:04:40.300 have the passenger, which is obviously the fetus. 00:04:40.300 --> 00:04:43.060 And for the passenger, we care deeply about the 00:04:43.060 --> 00:04:46.240 baby's size, their presentation, meaning what 00:04:46.240 --> 00:04:49.060 part of the body is coming first, and their attitude. 00:04:49.100 --> 00:04:52.519 Attitude. Grumpy about being born? Huh, no, though 00:04:52.519 --> 00:04:55.439 they usually are. Attitude refers to how their 00:04:55.439 --> 00:04:58.120 head and limbs are flexed or extended. Oh, got 00:04:58.120 --> 00:04:59.800 it. Like, are they tucked into a tight little 00:04:59.800 --> 00:05:01.959 cannonball, or are they stretching out? Exactly 00:05:01.959 --> 00:05:05.589 that. A tightly flexed head, chin to chest, presents 00:05:05.589 --> 00:05:08.730 the absolute smallest possible diameter to the 00:05:08.730 --> 00:05:11.189 maternal pelvis. Which is what we want. Right. 00:05:11.329 --> 00:05:13.470 But if the baby extends its neck, like looking 00:05:13.470 --> 00:05:16.329 up at the ceiling, suddenly the widest part of 00:05:16.329 --> 00:05:18.790 the head is trying to squeeze through that narrow 00:05:18.790 --> 00:05:21.930 space, which can literally stall labor entirely. 00:05:22.449 --> 00:05:25.329 Ouch. Okay, and that brings us to the third P. 00:05:25.550 --> 00:05:28.740 Yes, the passage. which is the maternal bony 00:05:28.740 --> 00:05:31.259 pelvis and all the soft tissues of the birth 00:05:31.259 --> 00:05:33.779 canal. So we have the engine pushing, the passenger 00:05:33.779 --> 00:05:36.180 navigating, and the tunnel they have to get through. 00:05:36.459 --> 00:05:38.519 That's the setup. But to figure out if this is 00:05:38.519 --> 00:05:40.839 actually working, we have to measure the cervix. 00:05:41.180 --> 00:05:43.699 And I have to say, this is where I remember getting 00:05:43.699 --> 00:05:46.040 completely tangled up in nursing school. That 00:05:46.040 --> 00:05:48.839 terminology can be a lot. It is. Effacement, 00:05:49.180 --> 00:05:51.339 dilation, station, they just kind of blur together. 00:05:51.639 --> 00:05:53.689 Let's untangle them for the listeners. Okay, 00:05:53.870 --> 00:05:57.110 think of the cervix before labor as a thick, 00:05:57.610 --> 00:06:01.209 firm cylinder. kind of like a really rigid turtleneck 00:06:01.209 --> 00:06:03.410 sweater neck about two to three centimeters long. 00:06:03.649 --> 00:06:06.110 Okay, a rigid turtleneck. Yeah. And it is tightly 00:06:06.110 --> 00:06:08.829 closed to keep the baby safely inside. But when 00:06:08.829 --> 00:06:12.089 labor begins, the power, those contractions we 00:06:12.089 --> 00:06:15.009 talked about, starts pulling that cylinder upward, 00:06:15.410 --> 00:06:17.189 stretching it over the baby's head. So it's pulling 00:06:17.189 --> 00:06:20.009 the turtleneck up and over. Exactly. So a facement 00:06:20.009 --> 00:06:22.310 is just the measurement of how much that cylinder 00:06:22.310 --> 00:06:25.220 has shortened and thinned out. So it goes from 00:06:25.220 --> 00:06:27.899 being a thick tube to something like a really 00:06:27.899 --> 00:06:30.699 thin sheet of paper. And we measure that in percentages, 00:06:30.980 --> 00:06:33.699 right? Correct. 0 % effaced means it is still 00:06:33.699 --> 00:06:37.100 a thick, completely unchanged tube. And 100 %? 00:06:37.180 --> 00:06:39.779 100 % of faced means it is completely thinned 00:06:39.779 --> 00:06:42.360 out. You practically can't even feel it distinguishing 00:06:42.360 --> 00:06:44.519 from the rest of the lower uterus. OK, so if 00:06:44.519 --> 00:06:47.500 a faceman is thinning, then dilation is the actual 00:06:47.500 --> 00:06:49.959 opening of the door. Yes. Dilation is measured 00:06:49.959 --> 00:06:52.399 in centimeters from 0, which is locked closed, 00:06:52.819 --> 00:06:56.000 to 10 centimeters, which is fully open. 10 centimeters 00:06:56.000 --> 00:06:58.399 is the magic number. Right, because 10 centimeters 00:06:58.399 --> 00:07:00.560 is generally considered large enough for a full 00:07:00.560 --> 00:07:03.360 -term fetal head to pass through? Now here is 00:07:03.360 --> 00:07:05.980 the metric that always feels like a trap on exams. 00:07:06.439 --> 00:07:09.279 Like, I always got this wrong. Fetal station. 00:07:10.279 --> 00:07:13.480 Oh, the numbering system. Yes. When I first learned 00:07:13.480 --> 00:07:16.279 this, the numbering system felt completely counterintuitive. 00:07:16.569 --> 00:07:18.889 because normally negative numbers mean you're 00:07:18.889 --> 00:07:21.389 below something and positive numbers mean you're 00:07:21.389 --> 00:07:24.050 above it. But in obstetrics, it's flipped. Right. 00:07:24.310 --> 00:07:26.730 Negative numbers mean the baby is high up and 00:07:26.730 --> 00:07:30.009 positive numbers mean the baby is low down. Why? 00:07:30.550 --> 00:07:33.259 How does this map out? physically. I totally 00:07:33.259 --> 00:07:35.420 see why that gets people. You really have to 00:07:35.420 --> 00:07:37.639 understand what the zero line is. Okay, where 00:07:37.639 --> 00:07:39.939 is zero? In the middle of the maternal pelvis, 00:07:40.139 --> 00:07:42.540 there are these two bony prominences called the 00:07:42.540 --> 00:07:45.060 ischal spines. If you look at a pelvic skeleton, 00:07:45.300 --> 00:07:47.519 these spines jut inward. Like little spikes. 00:07:47.699 --> 00:07:51.699 Yeah. They represent the absolute narrowest anatomical 00:07:51.699 --> 00:07:54.319 bottleneck that the baby has to navigate. Because 00:07:54.319 --> 00:07:56.769 it's the ultimate choke point, Obstetricians 00:07:56.769 --> 00:07:59.509 and nurses use the ischial spines as the zero 00:07:59.509 --> 00:08:03.189 landmark. Ah, okay. So zero is the equator, the 00:08:03.189 --> 00:08:06.149 choke point. Exactly. If the widest part of the 00:08:06.149 --> 00:08:08.769 baby's head, the biparietal diameter, has reached 00:08:08.769 --> 00:08:12.009 the level of those ischial spines, we say the 00:08:12.009 --> 00:08:15.089 baby is at zero station. Which means what clinically? 00:08:15.569 --> 00:08:18.329 The baby has officially entered the true pelvis. 00:08:18.870 --> 00:08:22.209 Clinically, we call this being engaged. Engaged, 00:08:22.329 --> 00:08:24.870 like they are locked in. Right. It's a very reassuring 00:08:24.870 --> 00:08:27.170 sign because it proves the baby's head actually 00:08:27.170 --> 00:08:29.550 fits into the pelvic inlet. That makes so much 00:08:29.550 --> 00:08:32.429 more sense. So if zero is the choke point... 00:08:32.139 --> 00:08:34.799 Any number above that choke point is negative? 00:08:34.980 --> 00:08:37.360 Right. If the presenting part is above the ischal 00:08:37.360 --> 00:08:39.700 spines, we measure the distance in centimeters 00:08:39.700 --> 00:08:42.559 as negative numbers. So minus one, minus two, 00:08:42.620 --> 00:08:45.379 minus three. So minus five is? If a baby is at 00:08:45.379 --> 00:08:47.639 minus five station, it's essentially floating 00:08:47.639 --> 00:08:50.720 high up in the false pelvis, completely unengaged. 00:08:50.899 --> 00:08:53.059 Which means positive numbers are a positive sign 00:08:53.059 --> 00:08:56.440 of progress. Yes. That's a fantastic memory anchor 00:08:56.440 --> 00:08:59.019 for exams. Because students see a positive number 00:08:59.019 --> 00:09:02.120 and freak out. Exactly. Students see a patient 00:09:02.120 --> 00:09:04.940 is at verse plus three station, and they panic, 00:09:05.559 --> 00:09:07.659 thinking a high positive number means a high 00:09:07.659 --> 00:09:10.659 level of danger. But plus one, plus two, plus 00:09:10.659 --> 00:09:12.440 three just means the baby has passed the hardest 00:09:12.440 --> 00:09:14.440 part and is moving down the birth canal toward 00:09:14.440 --> 00:09:16.639 the exit. And plus four, five. Plus four, plus 00:09:16.639 --> 00:09:18.980 five means the head is crowning at the perineum. 00:09:19.500 --> 00:09:21.899 So positive numbers mean positive progress toward 00:09:21.899 --> 00:09:24.840 birth. I love that. Positive numbers equal positive 00:09:24.840 --> 00:09:28.159 progress. Okay, so we check the dashboard. The 00:09:28.159 --> 00:09:30.539 patient is 100 % effaced. She's five centimeters 00:09:30.539 --> 00:09:34.659 dilated and at zero station. What do we actually 00:09:34.659 --> 00:09:37.320 do with this data? Why do nursing instructors 00:09:37.320 --> 00:09:40.360 obsess over mapping these exact numbers? Because 00:09:40.360 --> 00:09:43.120 labor is a continuum, right? But clinically, 00:09:43.120 --> 00:09:46.320 we slice it into four distinct functional stages. 00:09:46.559 --> 00:09:48.779 And your nursing interventions completely change 00:09:48.779 --> 00:09:50.940 depending on which stage the patient is currently 00:09:50.940 --> 00:09:53.100 in. So if you get the stage wrong? If you don't 00:09:53.100 --> 00:09:54.720 know where she is on the map, you will choose 00:09:54.720 --> 00:09:57.149 the wrong intervention. which is an immediate 00:09:57.149 --> 00:09:59.789 safety failure on an exam and obviously in real 00:09:59.789 --> 00:10:02.610 life. Let's map out the journey then from the 00:10:02.610 --> 00:10:04.649 first contraction to the recovery room. Walk 00:10:04.649 --> 00:10:07.409 me through the stages. All right. Stage one is 00:10:07.409 --> 00:10:10.190 all about getting the door open. It starts with 00:10:10.190 --> 00:10:14.129 the onset of true, regular contractions, and 00:10:14.129 --> 00:10:16.990 it doesn't end until the cervix is completely 00:10:16.990 --> 00:10:19.370 dilated to 10 centimeters. So it's the longest 00:10:19.370 --> 00:10:22.049 part? By far. It is the longest stage, and it's 00:10:22.049 --> 00:10:25.450 further divided into phases. The early or latent 00:10:25.450 --> 00:10:29.169 phase is really slow. The cervix might only dilate 00:10:29.169 --> 00:10:32.509 to 4 or 5 centimeters over many, many hours. 00:10:32.549 --> 00:10:35.250 And then... Then there is the active phase where 00:10:35.250 --> 00:10:37.210 the contractions become intense and the service 00:10:37.210 --> 00:10:40.210 dilates much more rapidly. Now wait, I want to 00:10:40.210 --> 00:10:42.110 pause on that word rapidly because I remember 00:10:42.110 --> 00:10:43.990 reading about something called the Friedman curve 00:10:43.990 --> 00:10:46.990 where doctors used to expect women to dilate 00:10:46.990 --> 00:10:50.309 like absolute clockwork. Oh yes, one centimeter 00:10:50.309 --> 00:10:52.570 per hour. Right, and if you didn't hit that mark 00:10:52.809 --> 00:10:55.009 They called it failure to progress and just wheeled 00:10:55.009 --> 00:10:57.590 you to the O .R. for a C -section. Is that still 00:10:57.590 --> 00:10:59.710 the gold standard? That is a phenomenal piece 00:10:59.710 --> 00:11:02.110 of historical context and honestly it's a major 00:11:02.110 --> 00:11:04.070 shift in modern obstetrics that you will be tested 00:11:04.070 --> 00:11:08.350 on. Oh really? Yes. Back in the 1950s, Dr. Emmanuel 00:11:08.350 --> 00:11:11.190 Friedman plotted thousands of labors on graph 00:11:11.190 --> 00:11:15.980 paper and created this sigmoid curve. that became 00:11:15.980 --> 00:11:18.679 the absolute law of labor and delivery. The law 00:11:18.679 --> 00:11:21.960 of the land. But here's the catch. Dr. Friedman's 00:11:21.960 --> 00:11:24.700 patients were largely laboring without epidurals, 00:11:25.039 --> 00:11:27.320 and the demographics of maternal weight and age 00:11:27.320 --> 00:11:30.000 back then were very, very different. Oh, wow. 00:11:30.159 --> 00:11:32.710 So the data's... Basically outdated. Completely 00:11:32.710 --> 00:11:35.590 outdated. Massive modern studies have shown that 00:11:35.590 --> 00:11:38.049 normal labor can be significantly slower than 00:11:38.049 --> 00:11:40.750 the old Friedman curve allowed, especially during 00:11:40.750 --> 00:11:42.990 that transition from the latent to the active 00:11:42.990 --> 00:11:45.690 phase. I imagine epidural changes things, too. 00:11:45.830 --> 00:11:48.370 Huge factor. An epidural can relax the pelvic 00:11:48.370 --> 00:11:51.110 floor beautifully, but it can also temporarily 00:11:51.110 --> 00:11:54.210 slow contractions. Today, we know that as long 00:11:54.210 --> 00:11:56.090 as the fetal monitor looks good and the mother 00:11:56.090 --> 00:11:58.730 is safe, we can give her more time. So we don't 00:11:58.730 --> 00:12:00.820 just rush to surgery. Exactly. We don't rush 00:12:00.820 --> 00:12:03.179 to a cesarean just because she stayed at six 00:12:03.179 --> 00:12:05.179 centimeters for three hours. That is sort of 00:12:05.179 --> 00:12:07.519 vital clinical insight. We are treating the patient, 00:12:07.740 --> 00:12:10.080 not a 70 -year -old graft. Exactly. OK, so stage 00:12:10.080 --> 00:12:11.980 one is getting to 10 centimeters. What is stage 00:12:11.980 --> 00:12:15.519 two? Stage two is the pushing stage. It begins 00:12:15.519 --> 00:12:18.159 the exact second the cervix hits 10 centimeters 00:12:18.159 --> 00:12:21.220 and ends with the actual physical birth of the 00:12:21.220 --> 00:12:23.860 infant. Wait, I want to clarify a huge trap I 00:12:23.860 --> 00:12:26.139 fell for in simulation lab. Oh, let's hear it. 00:12:26.279 --> 00:12:28.600 Okay, so if a patient is at eight centimeters, 00:12:29.299 --> 00:12:32.179 but she tells me, I feel incredible pressure 00:12:32.179 --> 00:12:35.610 I have to push right now. Isn't her body telling 00:12:35.610 --> 00:12:38.370 her what to do? Like, why shouldn't she push? 00:12:38.389 --> 00:12:40.730 Oh, this is one of the most highly tested safety 00:12:40.730 --> 00:12:43.970 priorities on the NCLEX. Really? Why? If she 00:12:43.970 --> 00:12:45.990 pushes before, the cervix is completely out of 00:12:45.990 --> 00:12:48.690 the way. She is forcing the baby's hard skull 00:12:48.690 --> 00:12:51.070 directly into the remaining cervical tissue. 00:12:51.289 --> 00:12:53.149 Like trying to force a golf ball through the 00:12:53.149 --> 00:12:55.549 neck of a tight sweater. Exactly like that. And 00:12:55.549 --> 00:12:57.990 what happens when you traumatize highly vascular 00:12:57.990 --> 00:13:00.590 tissue? It swells up. It swells massively. The 00:13:00.590 --> 00:13:02.850 cervix will become acutely edematous. It gets 00:13:02.850 --> 00:13:05.610 thick, swollen, and super rigid. And once it 00:13:05.610 --> 00:13:08.409 swells, it might stop dilating entirely. Oh, 00:13:08.409 --> 00:13:10.309 wow. So she could get stuck at eight centimeters 00:13:10.309 --> 00:13:13.090 permanently. Yes. You can literally stall the 00:13:13.090 --> 00:13:15.830 entire labor, turning a smooth vaginal birth 00:13:15.830 --> 00:13:18.370 into an emergency cesarean just because she pushed 00:13:18.370 --> 00:13:20.929 too early. That's terrifying. So what do I do 00:13:20.929 --> 00:13:23.090 as the nurse? As a nurse, you have to coach her 00:13:23.090 --> 00:13:25.809 through the contractions. You have her pan or 00:13:25.809 --> 00:13:28.029 blow out her breath like blowing out a candle 00:13:28.029 --> 00:13:31.450 to actively discourage pushing until you confirm 00:13:31.450 --> 00:13:34.210 she is fully at 10 centimeters. That is the why. 00:13:34.409 --> 00:13:36.389 That makes the fact stick. You blow out the candle 00:13:36.389 --> 00:13:40.070 to save the cervix. OK, stage three is delivering 00:13:40.070 --> 00:13:42.889 the placenta. And most people think the story 00:13:42.889 --> 00:13:46.820 ends there. But there is a stage four. Yes. Stage 00:13:46.820 --> 00:13:49.779 four is the immediate postpartum period, roughly 00:13:49.779 --> 00:13:52.080 the first two to four hours after the placenta 00:13:52.080 --> 00:13:54.419 delivers. When everyone is passing the baby around 00:13:54.419 --> 00:13:56.340 and taking pictures. Right. The adrenaline of 00:13:56.340 --> 00:13:59.659 birth wears off. The room empties out. But physiologically, 00:14:00.100 --> 00:14:03.299 this is where maternal biology undergoes a massive 00:14:03.299 --> 00:14:06.580 violent shift. It is the highest risk time frame 00:14:06.580 --> 00:14:09.200 for maternal mortality due to postpartum hemorrhage. 00:14:09.259 --> 00:14:11.659 Because the placenta just detached from the wall 00:14:11.659 --> 00:14:14.440 of the uterus, leaving a massive open wound essentially. 00:14:14.759 --> 00:14:17.019 A wound the exact size of a dinner plate with 00:14:17.019 --> 00:14:19.440 mass or blood vessels completely sheared open. 00:14:19.720 --> 00:14:22.659 Which sounds fatal. So how does she not just 00:14:22.659 --> 00:14:26.000 bleed to death? The uterus is an incredibly powerful 00:14:26.000 --> 00:14:30.659 muscle. In a healthy stage four, the uterus dramatically 00:14:30.659 --> 00:14:33.799 clamps down, contracting tightly to physically 00:14:33.799 --> 00:14:37.019 pinch those bleeding vessels closed. It's a biological 00:14:37.019 --> 00:14:38.759 tourniquet. That is the perfect way to describe 00:14:38.759 --> 00:14:42.200 it. And as the nurse, how do I know if that biological 00:14:42.200 --> 00:14:44.159 tourniquet is actually working? What's the assessment? 00:14:44.500 --> 00:14:47.159 You systematically palpate the maternal abdomen. 00:14:47.679 --> 00:14:50.860 You press your hand into her lower belly to feel 00:14:50.860 --> 00:14:53.220 the fundus, which is the top of the uterus. What 00:14:53.220 --> 00:14:55.850 should it feel like? It should feel firm, like 00:14:55.850 --> 00:14:58.210 a hard grapefruit, located right around the level 00:14:58.210 --> 00:15:00.269 of her belly button. And if it doesn't. If you 00:15:00.269 --> 00:15:02.950 press down and it feels soft, squishy, like a 00:15:02.950 --> 00:15:05.549 water balloon, we call that a boggy uterus. Yeah. 00:15:05.789 --> 00:15:07.990 You are in a life -threatening crisis called 00:15:07.990 --> 00:15:11.490 uterine atony. Uterine atony. The muscle is exhausted 00:15:11.490 --> 00:15:13.909 and it's just relaxed, letting the blood flow 00:15:13.909 --> 00:15:16.250 freely. Yes. What is the immediate priority? 00:15:16.470 --> 00:15:19.110 Do I run and get the doctor? You do not leave 00:15:19.110 --> 00:15:20.929 the room to call the doctor. Okay, good to know. 00:15:21.090 --> 00:15:23.590 You drop your hands to her abdomen and you perform 00:15:23.590 --> 00:15:27.990 vigorous fundal massage. Very vigorous. You physically 00:15:27.990 --> 00:15:31.250 squeeze and knead that uterus through her abdomen 00:15:31.250 --> 00:15:33.710 to irritate the muscle fibers into contracting. 00:15:34.350 --> 00:15:36.730 It is painful for the patient, but it is 100 00:15:36.730 --> 00:15:39.730 % life -saving. And what else? I can't just massage 00:15:39.730 --> 00:15:42.129 forever. At the same time, you are yelling for 00:15:42.129 --> 00:15:45.590 help and preparing to administer uterotonic medications. 00:15:45.769 --> 00:15:49.090 Things like Peterson, Methargyne, or Hemabate 00:15:49.090 --> 00:15:51.909 to chemically force the muscle to clamp down. 00:15:52.029 --> 00:15:53.649 Let's touch on those meds really quickly because 00:15:53.649 --> 00:15:56.190 pharmacology is huge on a Peterson, we know, 00:15:56.470 --> 00:15:59.190 but what about methadine and hemabate? Any traps 00:15:59.190 --> 00:16:02.190 there? Huge traps. Methadine raises blood pressure. 00:16:02.549 --> 00:16:04.970 So if your patient has preeclampsia or high blood 00:16:04.970 --> 00:16:07.909 pressure, methadine is strictly contraindicated. 00:16:08.169 --> 00:16:11.090 You will cause a stroke. Wow, okay. High BP means 00:16:11.090 --> 00:16:14.580 no methadine. and hemabate. Hemabate causes severe 00:16:14.580 --> 00:16:16.580 bronchospasm. So if your patient has a history 00:16:16.580 --> 00:16:18.879 of asthma, hemabate is contraindicated. See, 00:16:18.879 --> 00:16:20.500 this is why I love digging into the mechanisms. 00:16:20.720 --> 00:16:23.240 Massage to the fundus sounds like a gentle spa 00:16:23.240 --> 00:16:25.980 treatment. Vigorously compress the bleeding organ 00:16:25.980 --> 00:16:28.799 and cross -check asthma meds to stop a hemorrhage 00:16:28.799 --> 00:16:30.940 is the reality. Exactly. OK, before we move on 00:16:30.940 --> 00:16:32.720 from the dashboard, we talked about checking 00:16:32.720 --> 00:16:34.539 the cervix to get all these measurements. But 00:16:34.539 --> 00:16:37.379 is there ever a time when you absolutely should 00:16:37.379 --> 00:16:40.769 not perform a vaginal exam? Yes. And this is 00:16:40.769 --> 00:16:42.750 a guaranteed exam question. Status nurse, pen 00:16:42.750 --> 00:16:45.610 and paper out. If a patient arrives in triage 00:16:45.610 --> 00:16:48.850 complaining of bright red, undiagnosed vaginal 00:16:48.850 --> 00:16:51.750 bleeding, a digital vaginal exam is strictly 00:16:51.750 --> 00:16:55.350 contraindicated. Why? If she's bleeding, shouldn't 00:16:55.350 --> 00:16:57.289 I find out where the blood is coming from? Because 00:16:57.289 --> 00:16:59.190 you might be the cause of her bleeding to death. 00:16:59.639 --> 00:17:03.279 Wait, really? Yes. She could have a condition 00:17:03.279 --> 00:17:06.519 called placenta previa, where the placenta has 00:17:06.519 --> 00:17:09.740 implanted abnormally low in the uterus, completely 00:17:09.740 --> 00:17:12.519 covering the cervical opening. Oh, wow. If you 00:17:12.519 --> 00:17:14.539 blindly insert your fingers into the cervix, 00:17:14.839 --> 00:17:17.880 you could literally punch right through the highly 00:17:17.880 --> 00:17:20.279 vascular placenta. You will cause a catastrophic 00:17:20.279 --> 00:17:22.599 hemorrhage that will exsanguinate the baby and 00:17:22.599 --> 00:17:25.180 the mother in minutes. That is terrifying. So 00:17:25.180 --> 00:17:27.359 you must wait for a transvaginal ultrasound to 00:17:27.359 --> 00:17:29.279 locate the placenta before anyone touches it. 00:17:29.200 --> 00:17:32.480 her cervix. Okay, that is a massive safety priority. 00:17:32.859 --> 00:17:36.579 Never check a bleeding cervix blindly. So we've 00:17:36.579 --> 00:17:38.680 covered the mother's dashboard. We understand 00:17:38.680 --> 00:17:41.599 the physical machinery of labor, but there is 00:17:41.599 --> 00:17:43.759 a second patient in the room. The one we can't 00:17:43.759 --> 00:17:47.299 see. Exactly. Let's pivot to how we know if the 00:17:47.299 --> 00:17:50.200 baby is surviving this journey. This brings us 00:17:50.200 --> 00:17:53.730 to electronic fetal heart rate monitoring. I 00:17:53.730 --> 00:17:56.369 feel like this is the holy grail of obstetrics 00:17:56.369 --> 00:17:59.329 exams. It absolutely is because, as we said earlier, 00:17:59.670 --> 00:18:02.609 the fetal monitor is the baby's only voice. During 00:18:02.609 --> 00:18:06.190 labor, the baby is subjected to tremendous mechanical 00:18:06.190 --> 00:18:09.009 and hypoxic stress. Hypoxic stress. Yeah, every 00:18:09.009 --> 00:18:11.509 time the uterus contracts, it temporarily squeezes 00:18:11.509 --> 00:18:13.990 the blood vessels in the placenta, briefly cutting 00:18:13.990 --> 00:18:16.049 off the baby's oxygen supply. It's like doing 00:18:16.049 --> 00:18:17.710 a strenuous workout where someone just pinches 00:18:17.710 --> 00:18:20.609 your nose every three minutes. Precisely. A healthy, 00:18:20.930 --> 00:18:23.410 well -oxygenated fetus with good reserves can 00:18:23.410 --> 00:18:25.650 tolerate that intermittent stress perfectly fine. 00:18:26.170 --> 00:18:28.950 A fetus that is compromised cannot. The monitor 00:18:28.950 --> 00:18:31.470 translates their neurological and cardiovascular 00:18:31.470 --> 00:18:33.589 response to that stress right onto a strip of 00:18:33.589 --> 00:18:35.650 paper. So we need to learn how to read the language 00:18:35.650 --> 00:18:38.289 of the monitor. The guidelines group tracings 00:18:38.289 --> 00:18:40.829 into a three -tier system, right? Category one, 00:18:40.970 --> 00:18:43.569 two, and three. Let's start with category one. 00:18:44.130 --> 00:18:47.059 This is the perfect A -plus baby. Category 1 00:18:47.059 --> 00:18:49.539 is normal. It tells you the fetal acid base status 00:18:49.539 --> 00:18:51.880 is perfectly balanced. What are the rules to 00:18:51.880 --> 00:18:54.740 be category 1? To earn a category 1 rating, the 00:18:54.740 --> 00:18:58.079 tracing must meet strict criteria. First, the 00:18:58.079 --> 00:19:01.039 baseline heart rate must be between 110 and 160 00:19:01.039 --> 00:19:03.960 beats per minute. 110 to 160. Got it. Second, 00:19:04.119 --> 00:19:06.660 and most importantly, the baseline variability 00:19:06.660 --> 00:19:10.000 must be moderate. I want to spend some time on 00:19:10.000 --> 00:19:11.839 variability because I remember staring at these 00:19:11.839 --> 00:19:14.900 drifts and just seeing jagged lines. What does 00:19:14.900 --> 00:19:17.460 variability actually mean biologically? It is 00:19:17.460 --> 00:19:19.259 the most beautiful thing you can see on a monitor. 00:19:19.819 --> 00:19:22.200 Variability refers to the tiny, beat -to -beat 00:19:22.200 --> 00:19:24.160 fluctuations in the heart rate. Like it shouldn't 00:19:24.160 --> 00:19:26.299 be smooth. Right. If you look at the tracing, 00:19:26.640 --> 00:19:28.200 it shouldn't look like a straight line drawn 00:19:28.200 --> 00:19:30.940 with a ruler. It should look erratic, jagged, 00:19:31.180 --> 00:19:34.420 squiggly. But why is erratic good? Usually in 00:19:34.420 --> 00:19:37.700 adult cardiology, erratic means you have an arrhythmia 00:19:37.700 --> 00:19:40.880 and you're about to code. True, but in a fetus, 00:19:41.119 --> 00:19:43.400 it proves that the central nervous system is 00:19:43.400 --> 00:19:46.819 intact, oxygenated, and functioning. How so? 00:19:47.019 --> 00:19:49.859 The fetal heart is in a constant tug of war between 00:19:49.859 --> 00:19:52.319 the sympathetic nervous system, which acts like 00:19:52.319 --> 00:19:54.940 the gas pedal trying to speed the heart up. Okay. 00:19:55.079 --> 00:19:57.559 Sympathetic is the gas. And the parasympathetic 00:19:57.559 --> 00:20:00.000 nervous system via the vagus nerve, which acts 00:20:00.000 --> 00:20:02.319 like the brakes trying to slow it down. Gas brake, 00:20:02.359 --> 00:20:05.920 gas brake. Exactly. When a healthy oxygenated 00:20:05.920 --> 00:20:08.799 fetal brain is managing that tug of war, the 00:20:08.799 --> 00:20:11.519 heart rate constantly microadjusts, creating 00:20:11.519 --> 00:20:15.039 that squiggly line. We call it moderate variability 00:20:15.039 --> 00:20:18.099 when those fluctuations are between 6 and 25 00:20:18.099 --> 00:20:20.339 beats per minute in amplitude. So if you see 00:20:20.339 --> 00:20:22.640 modern variability. You can take a deep breath 00:20:22.640 --> 00:20:24.920 because it virtually guarantees the the baby's 00:20:24.920 --> 00:20:27.900 brain is not hypoxic or acidotic at that exact 00:20:27.900 --> 00:20:30.279 moment. Okay, so squiggly means the brain is 00:20:30.279 --> 00:20:32.619 awake and fighting. What is the opposite? What 00:20:32.619 --> 00:20:35.740 makes a tracing category three the ultimate emergency? 00:20:36.140 --> 00:20:38.700 Category three means severe fetal hypoxia and 00:20:38.700 --> 00:20:41.059 acidemia. The brain is literally shutting down. 00:20:41.160 --> 00:20:43.440 And what does that look like? The hallmark of 00:20:43.440 --> 00:20:45.980 a category three strip is absent variability. 00:20:46.839 --> 00:20:49.619 The line goes completely flat, smooth, like a 00:20:49.619 --> 00:20:51.619 ruler. Because the brain doesn't have enough 00:20:51.619 --> 00:20:53.619 oxygen to manage the gas and the brake pedals 00:20:53.619 --> 00:20:56.119 anymore. Right. The nervous system is deeply 00:20:56.119 --> 00:20:59.460 depressed. But absent variability alone isn't 00:20:59.460 --> 00:21:02.059 automatically category three. I mean, maybe the 00:21:02.059 --> 00:21:05.460 baby is just in a deep sleep cycle or the mother 00:21:05.460 --> 00:21:07.640 had narcotic pain medication. Oh, that makes 00:21:07.640 --> 00:21:10.200 sense. Meds crossed the placenta. Exactly. It 00:21:10.200 --> 00:21:12.299 becomes a category three emergency when that 00:21:12.299 --> 00:21:15.579 flat line is combined with pathological decelerations, 00:21:15.880 --> 00:21:19.680 specifically recurrent late decelerations, recurrent 00:21:19.680 --> 00:21:23.059 severe variable decelerations, or persistent 00:21:23.059 --> 00:21:25.980 profound bradycardia. OK, let's unpack these 00:21:25.980 --> 00:21:27.839 decelerations. These are the heart rate drops 00:21:27.839 --> 00:21:30.440 that happen during the tracing. There are early 00:21:30.440 --> 00:21:33.019 late, and variable decelerations. They sound 00:21:33.019 --> 00:21:35.460 simple, but I know their underlying physiology 00:21:35.460 --> 00:21:37.420 is entirely different. Completely different. 00:21:37.460 --> 00:21:40.299 Let's start with early decelerations. Early decelerations 00:21:40.299 --> 00:21:43.400 are visually apparent gradual symmetrical decreases 00:21:43.400 --> 00:21:45.839 in the fetal heart rate. They look like gentle, 00:21:46.180 --> 00:21:48.559 shallow U shapes. Okay, shallow U shapes. But 00:21:48.559 --> 00:21:50.819 the defining characteristic is their timing. 00:21:51.840 --> 00:21:54.839 They perfectly mirror the uterine contraction. 00:21:55.359 --> 00:21:57.380 Meaning, as the contraction gets stronger and 00:21:57.380 --> 00:21:59.500 goes up on the bottom half of the monitor paper, 00:22:00.059 --> 00:22:02.319 the fetal heart rate goes down on the top half. 00:22:02.400 --> 00:22:05.259 Yes. The lowest point of the heart rate drop, 00:22:05.359 --> 00:22:08.359 the nadir, occurs at the exact same moment as 00:22:08.359 --> 00:22:10.819 the peak of the contraction. Okay, I'm putting 00:22:10.819 --> 00:22:13.319 myself in the student's shoes here. A contraction 00:22:13.319 --> 00:22:16.980 squeezes the baby, heart rate drops. That sounds 00:22:16.980 --> 00:22:21.500 bad. Why is this considered an expected... normal 00:22:21.500 --> 00:22:23.980 finding. Because of why it's happening. Early 00:22:23.980 --> 00:22:26.460 decelerations are caused by pure mechanical head 00:22:26.460 --> 00:22:28.519 compression. Head compression. As the uterus 00:22:28.519 --> 00:22:31.180 contracts it forcefully swishes the baby's skull 00:22:31.180 --> 00:22:34.210 against the maternal pelvis. This physical pressure 00:22:34.210 --> 00:22:36.750 on the skull stimulates the fetal vagus nerve, 00:22:37.150 --> 00:22:39.150 which reflexively slows the heart rate. Just 00:22:39.150 --> 00:22:42.470 a reflex. Exactly. As the contraction fades and 00:22:42.470 --> 00:22:44.329 the pressure releases, the heart rate returns 00:22:44.329 --> 00:22:46.690 to normal. So it's not a lack of oxygen. Not 00:22:46.690 --> 00:22:48.490 at all. It just means the head is descending 00:22:48.490 --> 00:22:50.490 into the birth canal. It's actually a sign of 00:22:50.490 --> 00:22:53.089 progress. So what's the nursing action? The appropriate 00:22:53.089 --> 00:22:55.630 nursing action for early decelerations is to 00:22:55.630 --> 00:22:58.369 simply document the finding and perhaps perform 00:22:58.369 --> 00:23:01.190 a vaginal exam to see if the patient is fully 00:23:01.190 --> 00:23:03.609 dilated and ready to push. Okay, that makes sense. 00:23:03.829 --> 00:23:06.029 Now let's shift to late decelerations. These 00:23:06.029 --> 00:23:08.250 are the bad ones. How do they look different 00:23:08.250 --> 00:23:11.990 and why are they so dangerous? Visually, late 00:23:11.990 --> 00:23:15.809 decelerations are also gradual, shallow U -shapes. 00:23:15.869 --> 00:23:18.450 So they look the same as earlys? Visually, yes. 00:23:19.009 --> 00:23:22.369 But their timing is shifted to the right. The 00:23:22.369 --> 00:23:25.069 deceleration does not start until after the contraction 00:23:25.069 --> 00:23:27.430 has reached its peak. After the peak. And the 00:23:27.430 --> 00:23:29.650 heart rate doesn't return to baseline until well 00:23:29.650 --> 00:23:31.809 after the contraction has completely ended. So 00:23:31.809 --> 00:23:33.910 the contraction peaks and then a moment later 00:23:33.910 --> 00:23:36.109 the heart rate bottoms out. Right. Why the delay? 00:23:36.250 --> 00:23:38.490 Because this isn't a mechanical reflex. This 00:23:38.490 --> 00:23:41.589 is utero placental insufficiency. It is a true 00:23:41.589 --> 00:23:44.049 oxygen crisis. Let's walk through the plumbing 00:23:44.049 --> 00:23:46.390 of that. What is actually failing? Well, the 00:23:46.390 --> 00:23:49.119 placenta is essentially the baby's lung. Maternal 00:23:49.119 --> 00:23:52.200 blood flows into the placenta, transferring oxygen 00:23:52.200 --> 00:23:55.299 to the fetal blood. But during the peak of a 00:23:55.299 --> 00:23:58.099 contraction, the uterine muscle clamps down so 00:23:58.099 --> 00:24:00.640 tightly that it physically halts the flow of 00:24:00.640 --> 00:24:02.980 maternal blood into the placenta. Like stepping 00:24:02.980 --> 00:24:05.900 on a garden hose. Exactly. For a few seconds, 00:24:06.039 --> 00:24:09.710 the baby gets no new oxygen. Now, a healthy placenta 00:24:09.710 --> 00:24:12.329 has built up oxygen reserves in the intervillus 00:24:12.329 --> 00:24:15.170 spaces, so the baby basically holds its breath, 00:24:15.490 --> 00:24:17.609 tolerates the squeeze, and its heart rate doesn't 00:24:17.609 --> 00:24:19.950 change. But if the placenta is failing? If it's 00:24:19.950 --> 00:24:22.349 failing, perhaps due to maternal hypertension, 00:24:22.789 --> 00:24:25.970 gestational diabetes, preeclampsia, or simply 00:24:25.970 --> 00:24:28.369 because the mother is two weeks past her due 00:24:28.369 --> 00:24:30.849 date, those reserves are completely gone. So 00:24:30.849 --> 00:24:33.269 when the contraction peaks and steps on the hose, 00:24:33.730 --> 00:24:35.670 the baby instantly runs out of air. Right. And 00:24:35.670 --> 00:24:38.029 as the oxygen level in the fetal blood plummets, 00:24:38.269 --> 00:24:40.690 chemoreceptors in the baby's brain detect the 00:24:40.690 --> 00:24:43.190 hypoxia and trigger the heart rate to slow down 00:24:43.190 --> 00:24:45.990 in a desperate attempt to conserve myocardial 00:24:45.990 --> 00:24:48.369 energy. It takes a moment for the oxygen level 00:24:48.369 --> 00:24:51.029 to drop, the brain to register it, and the heart 00:24:51.029 --> 00:24:53.589 to slow down. That's why the drop happens late. 00:24:53.759 --> 00:24:55.940 after the contraction has already peaked. Holding 00:24:55.940 --> 00:24:57.960 your breath on a treadmill when you already have 00:24:57.960 --> 00:25:01.160 bad lungs. That is a terrifying physiological 00:25:01.160 --> 00:25:04.059 picture. It is. So if you see recurrent late 00:25:04.059 --> 00:25:07.279 decelerations, you know the baby is suffocating. 00:25:07.660 --> 00:25:09.700 What about variable decelerations? How do they 00:25:09.700 --> 00:25:12.180 fit in? Early decels are gradual and mirror the 00:25:12.180 --> 00:25:14.740 contraction. Late decels are gradual and shifted 00:25:14.740 --> 00:25:18.299 right. Variable decelerations are abrupt. Abrupt, 00:25:18.420 --> 00:25:21.099 like a sharp drop. They are visually sheer cliffs. 00:25:21.400 --> 00:25:23.319 The heart rate plummets suddenly, dropping more 00:25:23.319 --> 00:25:26.000 than 15 beats per minute in less than 30 seconds. 00:25:26.380 --> 00:25:28.799 They look like sharp Vs or Ws on the tracing. 00:25:29.059 --> 00:25:31.779 OK, V for variable. Exactly. And they are variable 00:25:31.779 --> 00:25:33.480 because they can happen at any time. They don't 00:25:33.480 --> 00:25:35.579 have a strict relationship to the contractions. 00:25:35.759 --> 00:25:38.299 What causes a sheer cliff drop like that? Umbilical 00:25:38.299 --> 00:25:41.240 cord compression. The umbilical cord is the baby's 00:25:41.240 --> 00:25:43.319 lifeline. If it gets squished, maybe the baby 00:25:43.319 --> 00:25:45.440 rolls over on it, or the fluid is low and it 00:25:45.440 --> 00:25:47.440 gets pinched between the fetal shoulder and the 00:25:47.440 --> 00:25:50.880 uterine wall, the blood flow is instantly obstructed. 00:25:51.049 --> 00:25:52.789 And how does that instantly crash the heart rate? 00:25:52.930 --> 00:25:55.430 It's a baroreceptor response. When the cord is 00:25:55.430 --> 00:25:58.049 pinched, the fetal blood pressure skyrockets 00:25:58.049 --> 00:26:00.029 because the blood has nowhere to go. It was backs 00:26:00.029 --> 00:26:02.869 up. Right. Pressure sensors or baroreceptors 00:26:02.869 --> 00:26:05.130 in the fetal aorta scream at the brain, pressure 00:26:05.130 --> 00:26:08.430 is too high. The vagus nerve fires instantly, 00:26:08.789 --> 00:26:10.390 slamming the brakes on the heart to lower the 00:26:10.390 --> 00:26:13.029 blood pressure. When the cord is unpinched, the 00:26:13.029 --> 00:26:15.660 heart rate shoots right back up. It is amazing 00:26:15.660 --> 00:26:18.059 how much of this is just high stakes biological 00:26:18.059 --> 00:26:19.980 plumbing and electrical wiring. That's all it 00:26:19.980 --> 00:26:22.720 is. Okay, so as the nurse, you are staring at 00:26:22.720 --> 00:26:25.960 this monitor. You see a category two or category 00:26:25.960 --> 00:26:29.039 three strip say absent variability with recurrent 00:26:29.039 --> 00:26:32.640 late decelerations. The baby is hypoxic. What 00:26:32.640 --> 00:26:35.140 do you actually do? You immediately initiate 00:26:35.140 --> 00:26:37.740 intrarine resuscitation. Your singular goal is 00:26:37.740 --> 00:26:40.640 to maximize oxygen delivery to the placenta and 00:26:40.640 --> 00:26:43.039 improve umbilical blood flow. Do we use an acronym 00:26:43.039 --> 00:26:45.920 for this? I feel like nursing school's 90 % acronyms. 00:26:46.039 --> 00:26:49.859 Yes, the acronym LION is very helpful here. L 00:26:49.859 --> 00:26:53.740 for left lateral position, I for IV fluid bolus, 00:26:53.880 --> 00:26:57.140 O for oxygen, and N for notify provider and stop 00:26:57.140 --> 00:27:00.259 pitotin. Let's break down the Y for each one. 00:27:00.539 --> 00:27:03.299 Why change the mother's position first? If the 00:27:03.299 --> 00:27:05.640 mother is lying flat on her back, The entire 00:27:05.640 --> 00:27:08.299 weight of the gravid uterus crushes her inferior 00:27:08.299 --> 00:27:11.140 vena cava, drastically reducing blood return 00:27:11.140 --> 00:27:13.640 to her heart which drops her blood pressure and 00:27:13.640 --> 00:27:15.900 starves the placenta. A vena cava syndrome. Right. 00:27:16.200 --> 00:27:18.339 Rolling her to her left or right side takes the 00:27:18.339 --> 00:27:20.259 weight off the vena cava, restoring blood flow. 00:27:21.100 --> 00:27:23.640 Furthermore, if you are seeing variable decelerations 00:27:23.640 --> 00:27:26.220 from a compressed cord, physically shifting the 00:27:26.220 --> 00:27:28.079 mother's weight can literally cause the baby 00:27:28.079 --> 00:27:30.640 to float off the cord, instantly fixing the problem. 00:27:30.940 --> 00:27:33.359 So position change is always, always your first 00:27:33.359 --> 00:27:35.940 move for variables? Always. Okay, step two is 00:27:35.940 --> 00:27:38.640 an IV fluid bolus, usually lactated rengars. 00:27:38.799 --> 00:27:42.019 Why? Physics. More fluid volume in the maternal 00:27:42.019 --> 00:27:44.420 intravascular space equals higher maternal blood 00:27:44.420 --> 00:27:46.960 pressure, which equals stronger perfusion pressure 00:27:46.960 --> 00:27:49.269 driving blood into the placenta. Especially if 00:27:49.269 --> 00:27:52.009 she had epidural, right? Exactly, because epidurals 00:27:52.009 --> 00:27:54.710 cause vasodilation and drop maternal blood pressure 00:27:54.710 --> 00:27:58.890 anyway. Step three, oxygen. Applying a non -rebreather 00:27:58.890 --> 00:28:02.450 mask at 10 liters. Yes. You want to hyper oxygenate 00:28:02.450 --> 00:28:04.529 the maternal blood so that whatever blood is 00:28:04.529 --> 00:28:07.150 making it through the failing placenta is carrying 00:28:07.150 --> 00:28:10.309 maximum oxygen capacity to the fetus. And the 00:28:10.309 --> 00:28:12.349 final step, which might be the most critical. 00:28:13.279 --> 00:28:16.980 turning off the pitocin or oxytocin. If the contractions 00:28:16.980 --> 00:28:19.180 are the stressor causing the hypoxia, which they 00:28:19.180 --> 00:28:21.720 absolutely are in the case of late decelerations, 00:28:22.160 --> 00:28:25.079 you must stop the artificial engine driving the 00:28:25.079 --> 00:28:27.720 contractions. Turn off the engine. Pitocin forces 00:28:27.720 --> 00:28:30.220 the uterus to contract. You must turn it off 00:28:30.220 --> 00:28:32.700 immediately to give the placenta time to rest 00:28:32.700 --> 00:28:35.099 and refill with oxygen. Okay, let's talk exam 00:28:35.099 --> 00:28:37.079 traps for fetal monitoring. Where do students 00:28:37.079 --> 00:28:39.119 usually get tripped up? The most common trap 00:28:39.119 --> 00:28:41.759 is misinterpreting the baseline fetal heart rate. 00:28:42.009 --> 00:28:45.710 The normal range is 110 to 160. Students see 00:28:45.710 --> 00:28:49.470 a tracing where the baseline is 175. It's fetal 00:28:49.470 --> 00:28:51.490 tachycardia. And they think what? They often 00:28:51.490 --> 00:28:54.190 choose an answer like, the baby is active and 00:28:54.190 --> 00:28:56.549 tolerating labor well. Thinking a fast heart 00:28:56.549 --> 00:28:58.789 is a strong heart. Right, like the baby's just 00:28:58.789 --> 00:29:02.230 jogging. Exactly. But fetal tachycardia is a 00:29:02.230 --> 00:29:04.779 massive red flag. While it can be a side effect 00:29:04.779 --> 00:29:07.180 of maternal medications like tributylene, the 00:29:07.180 --> 00:29:09.799 most dangerous and testable cause of fetal tachycardia 00:29:09.799 --> 00:29:13.220 is maternal or intraamniotic infection called 00:29:13.220 --> 00:29:16.019 chorioamnionitis. Infection. The fetal heart 00:29:16.019 --> 00:29:18.099 rate will often spike hours before the mother 00:29:18.099 --> 00:29:21.400 even spikes a fever. It is an early warning siren 00:29:21.400 --> 00:29:24.759 for sepsis. That is a phenomenal clinical pearl. 00:29:25.119 --> 00:29:28.299 Tachycardia equals suspect infection. So up until 00:29:28.299 --> 00:29:29.920 now, we've been talking about this intricate 00:29:29.920 --> 00:29:32.059 dance of labor, assuming the timeline is normal, 00:29:32.079 --> 00:29:34.359 like a 39 or 40 -week term pregnancy. Right. 00:29:34.819 --> 00:29:37.059 But what happens when this entire physiological 00:29:37.059 --> 00:29:39.799 dashboard is abruptly moved up by, say, eight 00:29:39.799 --> 00:29:42.259 weeks? That changes the entire calculus of risk. 00:29:42.480 --> 00:29:45.079 A baby born at 40 weeks has fully developed lungs, 00:29:45.480 --> 00:29:47.599 plenty of brown fat for temperature regulation, 00:29:47.900 --> 00:29:50.920 and a mature liver. A baby born at 32 weeks has 00:29:50.920 --> 00:29:53.140 absolutely none of those things. Which bridges 00:29:53.140 --> 00:29:56.720 us perfectly into preterm labor, PP -ROM and 00:29:56.720 --> 00:29:59.799 intra -amniotic infection. Let's get the definitions 00:29:59.799 --> 00:30:02.000 crystal clear, because I know the NCLE -X loves 00:30:02.000 --> 00:30:04.819 to trick people here. What exactly is preterm 00:30:04.819 --> 00:30:07.950 labor? Preterm labor is defined as regular uterine 00:30:07.950 --> 00:30:10.829 contractions that cause actual measurable cervical 00:30:10.829 --> 00:30:13.430 change of facement or dilation occurring between 00:30:13.430 --> 00:30:16.809 20 weeks and 36 weeks and six days of gestation. 00:30:17.230 --> 00:30:19.690 The key phrase there is cervical change. Because 00:30:19.690 --> 00:30:21.930 a woman can have contractions at 30 weeks that 00:30:21.930 --> 00:30:24.029 aren't labor, right? Correct. A pregnant woman 00:30:24.029 --> 00:30:26.869 can experience Braxton Hicks contractions or 00:30:26.869 --> 00:30:29.390 contractions caused by dehydration or a urinary 00:30:29.390 --> 00:30:32.029 tract infection. So if she's just dehydrated? 00:30:32.049 --> 00:30:34.569 If the uterus is contracting but the cervix remains 00:30:34.569 --> 00:30:37.519 long - long, thick, and closed, she is not in 00:30:37.519 --> 00:30:40.000 preterm labor. We might hydrate her, treat the 00:30:40.000 --> 00:30:42.440 UTI, and send her home. But if those contractions 00:30:42.440 --> 00:30:44.240 are actually thinning and opening the cervix, 00:30:44.380 --> 00:30:46.859 she is in true preterm labor, and we have to 00:30:46.859 --> 00:30:52.059 intervene aggressively. PPPROM stands for preterm 00:30:52.059 --> 00:30:54.839 pre -labor rupture of membranes. This is when 00:30:54.839 --> 00:30:58.019 the amniotic sac, the bag of waters, spontaneously 00:30:58.019 --> 00:31:01.480 breaks before 37 weeks and before any contractions 00:31:01.480 --> 00:31:03.500 have even started. Why is that such a massive 00:31:03.500 --> 00:31:05.500 emergency? If the water breaks, doesn't that 00:31:05.500 --> 00:31:07.599 just mean the baby is coming? It's an emergency 00:31:07.599 --> 00:31:09.900 because of what the amniotic sac actually does. 00:31:10.019 --> 00:31:13.160 It is a thick, highly resilient, completely sterile 00:31:13.160 --> 00:31:16.319 barrier. It is a fortress that protects the fetus 00:31:16.319 --> 00:31:18.740 from the billions of bacteria residing in the 00:31:18.740 --> 00:31:21.369 vaginal canal. Oh, wow. When that sac ruptures 00:31:21.369 --> 00:31:23.829 prematurely, you have essentially lowered the 00:31:23.829 --> 00:31:26.410 drawbridge to the fortress. Bacteria can freely 00:31:26.410 --> 00:31:28.750 ascend from the vagina directly into the uterine 00:31:28.750 --> 00:31:31.730 cavity. Which leads to chorioamnionitis. Exactly. 00:31:32.269 --> 00:31:34.890 Chorioamnionitis is a severe ascending bacterial 00:31:34.890 --> 00:31:37.569 infection of the amniotic fluid, the membranes, 00:31:37.569 --> 00:31:40.470 and the placenta. It creates a highly toxic, 00:31:40.730 --> 00:31:43.730 inflammatory, interotorin environment. And that 00:31:43.730 --> 00:31:46.529 causes labor. It will trigger aggressive preterm 00:31:46.529 --> 00:31:49.049 labor, and if left untreated, it leads to maternal 00:31:49.049 --> 00:31:51.410 sepsis, fetal sepsis, and fetal brain damage. 00:31:51.529 --> 00:31:53.750 So how do you know if the fortress has been breached 00:31:53.750 --> 00:31:55.970 and an infection has taken hold? What are the 00:31:55.970 --> 00:31:58.410 signs? You look for the clinical hallmarks. We 00:31:58.410 --> 00:32:01.180 already mentioned the earliest sign. Fetal tachycardia. 00:32:01.359 --> 00:32:03.339 Right. Then you monitor the mother's temperature. 00:32:03.500 --> 00:32:06.960 A fever greater than 38 degrees Celsius or 100 00:32:06.960 --> 00:32:10.200 .4 degrees Fahrenheit is highly concerning. You 00:32:10.200 --> 00:32:13.240 also assess the mother's uterus. Is it exquisitely 00:32:13.240 --> 00:32:15.599 tender to the touch between contraction? Okay, 00:32:15.900 --> 00:32:18.359 tender uterus. And finally, you assess the amniotic 00:32:18.359 --> 00:32:20.660 fluid itself. What should it look like normally? 00:32:20.859 --> 00:32:24.279 Normal amniotic fluid is clear, pale, and relatively 00:32:24.279 --> 00:32:26.960 odorless. If the fluid leaking from the vagina 00:32:26.960 --> 00:32:30.849 is cloudy, yellow, purulent, or has a foul offensive 00:32:30.849 --> 00:32:34.190 odor, you are dealing with a severe intra -amniotic 00:32:34.190 --> 00:32:36.230 infection. OK, let's walk through a scenario. 00:32:36.529 --> 00:32:39.869 A patient arrives in triage at 31 weeks. She's 00:32:39.869 --> 00:32:42.430 having regular contractions, and her cervix has 00:32:42.430 --> 00:32:44.849 dilated from 1 centimeter to 3 centimeters in 00:32:44.849 --> 00:32:47.309 the last two hours. She is in active preterm 00:32:47.309 --> 00:32:50.390 labor. The water is intact. OK, classic preterm 00:32:50.390 --> 00:32:52.390 labor. What is our primary goal? Do we try to 00:32:52.390 --> 00:32:54.210 stop the labor completely and send her home to 00:32:54.210 --> 00:32:56.509 stay pregnant for another nine weeks? Generally, 00:32:56.730 --> 00:32:59.789 no. Once the biochemical cascade of true preterm 00:32:59.789 --> 00:33:03.009 labor has firmly established itself, it is incredibly 00:33:03.009 --> 00:33:05.869 difficult to halt it completely. Our primary 00:33:05.869 --> 00:33:08.230 realistic goal is to buy time. Specifically, 00:33:08.450 --> 00:33:11.549 we want to buy 48 hours. Why 48 hours? What are 00:33:11.549 --> 00:33:14.130 we doing in that window? We need that 48 hour 00:33:14.130 --> 00:33:17.490 window to administer intramuscular corticosteroids 00:33:17.490 --> 00:33:20.529 to the mother, usually a drug called beta -methasone. 00:33:20.849 --> 00:33:23.869 Why steroids? I normally associate steroids with 00:33:23.869 --> 00:33:26.309 reducing inflammation, like for asthma or an 00:33:26.309 --> 00:33:28.990 allergic reaction. In a premature fetus, the 00:33:28.990 --> 00:33:31.230 biggest threat to life is respiratory distress 00:33:31.230 --> 00:33:34.990 syndrome. A 31 -week fetal lung has not produced 00:33:34.990 --> 00:33:37.410 enough surfactant. Surfactant is the soapy stuff, 00:33:37.529 --> 00:33:39.569 right? Yes, the soapy substance that coats the 00:33:39.569 --> 00:33:41.869 inside of the alveoli and keeps them from collapsing 00:33:41.869 --> 00:33:44.349 flat every time the baby exhales. Without it, 00:33:44.430 --> 00:33:46.809 the lungs just stick together. When you inject 00:33:46.809 --> 00:33:49.150 beta -methasone into the mother, it crosses the 00:33:49.150 --> 00:33:51.210 placenta and aggressively stimulates the fetal 00:33:51.210 --> 00:33:53.609 lungs to synthesize and release surfactant. Oh, 00:33:53.609 --> 00:33:56.150 wow. So you are chemically accelerating fetal 00:33:56.150 --> 00:33:57.910 lung maturity while they're still in the womb. 00:33:58.039 --> 00:34:01.740 Exactly. But it takes about 24 to 48 hours for 00:34:01.740 --> 00:34:04.640 the drug to reach maximum efficacy. So we have 00:34:04.640 --> 00:34:06.880 to pause the contractions just long enough for 00:34:06.880 --> 00:34:08.699 the steroids to work. And how do we hit the pause 00:34:08.699 --> 00:34:11.940 button on labor? We use medications called tocolytics. 00:34:12.280 --> 00:34:14.860 Toco meaning labor, eslytic meaning to break 00:34:14.860 --> 00:34:18.079 or stop. These are smooth muscle relaxants. The 00:34:18.079 --> 00:34:20.559 sources list three primary high -yield drugs, 00:34:20.920 --> 00:34:23.960 terbutylene, nefetapine, and magnesium sulfate. 00:34:24.239 --> 00:34:26.380 Let's talk pharmacology because nurses administer 00:34:26.380 --> 00:34:28.400 these. Terbutylene. How does it work and what 00:34:28.400 --> 00:34:31.199 are the side effects? Tributylene is a beta -2 00:34:31.199 --> 00:34:34.260 adrenergic agonist. It binds to receptors in 00:34:34.260 --> 00:34:36.380 the uterine muscle and causes them to relax. 00:34:36.820 --> 00:34:39.500 However, it also binds to beta receptors in the 00:34:39.500 --> 00:34:42.719 heart and lungs. It is notorious for causing 00:34:42.719 --> 00:34:45.719 severe maternal tachycardia, palpitations, and 00:34:45.719 --> 00:34:47.960 tremors. The mother will often tell you she feels 00:34:47.960 --> 00:34:49.679 like her heart is beating right out of her chest. 00:34:49.739 --> 00:34:51.840 So what's the nursing implication? You must assess 00:34:51.840 --> 00:34:53.760 her heart rate before giving every single dose. 00:34:54.079 --> 00:34:56.960 If her pulse is already over 120, you hold the 00:34:56.960 --> 00:35:01.070 drug and notify the provider. Nifedipine. I recognize 00:35:01.070 --> 00:35:03.769 that as a blood pressure pill. Yes, it's a calcium 00:35:03.769 --> 00:35:06.170 channel blocker. The uterine muscle requires 00:35:06.170 --> 00:35:08.730 an influx of calcium into its cells to perform 00:35:08.730 --> 00:35:11.070 the actin myosin cross -bridging that causes 00:35:11.070 --> 00:35:14.429 a contraction. Nifedipine physically blocks the 00:35:14.429 --> 00:35:17.210 calcium channels. No calcium, no contraction. 00:35:17.690 --> 00:35:19.769 Brilliant. But it's a blood pressure med. Right. 00:35:19.849 --> 00:35:22.090 Because it relaxes smooth muscle everywhere, 00:35:22.449 --> 00:35:25.349 it also dilates maternal blood vessels. The major 00:35:25.349 --> 00:35:28.110 side effects are maternal hypertension, dizziness, 00:35:28.349 --> 00:35:30.849 and flushing. You have to monitor her blood pressure 00:35:30.849 --> 00:35:33.230 closely to ensure she doesn't bottom out and 00:35:33.230 --> 00:35:35.869 drop perfusion to the placenta. That makes perfect 00:35:35.869 --> 00:35:38.230 mechanical sense. Now let's talk about the heavy 00:35:38.230 --> 00:35:41.340 hitter, magnesium sulfate. I remember this being 00:35:41.340 --> 00:35:43.599 the most terrifying drug to manage on the L &D 00:35:43.599 --> 00:35:45.780 floor. Oh, it is a high alert medication because 00:35:45.780 --> 00:35:49.159 the therapeutic window is very narrow and magnesium 00:35:49.159 --> 00:35:52.619 toxicity can be fatal. So what does it do? Magnesium 00:35:52.619 --> 00:35:55.079 sulfate is a central nervous system depressant 00:35:55.079 --> 00:35:58.599 and a potent smooth muscle relaxant. It can be 00:35:58.599 --> 00:36:01.219 used as a tocolytic to relax the uterus. But 00:36:01.219 --> 00:36:03.599 there is a second highly testable reason we give 00:36:03.599 --> 00:36:06.219 it in preterm labor, completely separate from 00:36:06.219 --> 00:36:08.840 stopping contractions. Fetal neuroprotection. 00:36:09.239 --> 00:36:11.980 Massive studies showed that if you infuse magnesium 00:36:11.980 --> 00:36:15.159 sulfate into a mother delivering before 32 weeks, 00:36:15.739 --> 00:36:18.380 it stabilizes the fragile cerebral blood vessels 00:36:18.380 --> 00:36:21.320 in the extremely premature fetal brain. Wait, 00:36:21.420 --> 00:36:24.639 really? Yes. It drastically reduces the incidence 00:36:24.639 --> 00:36:27.059 and severity of devastating intraventricular 00:36:27.059 --> 00:36:29.699 hemorrhages and cerebral palsy in the neonate. 00:36:29.800 --> 00:36:32.420 So even if the labor is unstoppable and the baby's 00:36:32.420 --> 00:36:35.019 coming today, you still hang the mag to protect 00:36:35.019 --> 00:36:38.460 the baby's brain. Exactly. And your nursing priority, 00:36:38.559 --> 00:36:41.360 while the mother is on a mag drip, is assessing 00:36:41.360 --> 00:36:43.500 for toxicity. Right, because you said it's a 00:36:43.500 --> 00:36:45.320 CNS depressant. Because it depresses the nervous 00:36:45.320 --> 00:36:48.400 system, you must do hourly checks of her deep 00:36:48.400 --> 00:36:50.739 tendon reflexes, like the patellar knee jerk. 00:36:51.179 --> 00:36:53.400 If her reflexes disappear, her nervous system 00:36:53.400 --> 00:36:56.010 is too depressed. No, reflexes are bad. Very 00:36:56.010 --> 00:36:58.349 bad. You also check her respiratory rate. If 00:36:58.349 --> 00:37:00.570 it drops below 12 breaths per minute, the magnesium 00:37:00.570 --> 00:37:03.449 is paralyzing her diaphragm. Oh my god. If either 00:37:03.449 --> 00:37:05.869 of those happen, you immediately stop the infusion 00:37:05.869 --> 00:37:07.909 and prepare to administer the antidote, which 00:37:07.909 --> 00:37:10.889 is calcium gluconate. That is an absolute goldmine 00:37:10.889 --> 00:37:13.989 of exam prep right there. Lose the reflexes, 00:37:14.030 --> 00:37:17.329 stop the drug, grab the calcium gluconate. OK, 00:37:17.610 --> 00:37:19.949 what if the scenario is different? The patient 00:37:19.949 --> 00:37:24.659 is 32 weeks and her water breaks. PP prom. She's 00:37:24.659 --> 00:37:26.260 not having contractions yet, but the fortress 00:37:26.260 --> 00:37:30.420 is breached. What is our priority action? Infection 00:37:30.420 --> 00:37:32.900 prevention is your absolute paramount priority. 00:37:33.300 --> 00:37:36.260 You do not touch her cervix. You strictly limit 00:37:36.260 --> 00:37:39.139 or completely avoid digital vaginal exams. Because 00:37:39.139 --> 00:37:41.719 of the bacteria. Right. Every time a provider 00:37:41.719 --> 00:37:44.239 introduces a gloved hand into the vaginal canal, 00:37:44.659 --> 00:37:47.280 they are physically pushing ascending bacteria 00:37:47.280 --> 00:37:49.840 closer to the sterile uterine cavity. You manage 00:37:49.840 --> 00:37:52.079 her expectantly. What does expectant management 00:37:52.079 --> 00:37:54.760 look like? Monitoring her temperature, monitoring 00:37:54.760 --> 00:37:57.179 the fetal heart rate for tachycardia, assessing 00:37:57.179 --> 00:38:00.039 the fluid for foul odor, and administering prophylactic 00:38:00.039 --> 00:38:02.599 antibiotics to delay chorioamnionitis. Okay, 00:38:02.679 --> 00:38:04.360 we've covered the nuances of premature labor. 00:38:04.800 --> 00:38:06.480 Let's bring our timeline back to a full -term 00:38:06.480 --> 00:38:09.440 pregnancy. Back to 40 weeks. Yes. The patient 00:38:09.440 --> 00:38:12.679 is 40 weeks. She's fully dilated. The monitor 00:38:12.679 --> 00:38:14.980 looks okay. The baby's is coming down the birth 00:38:14.980 --> 00:38:19.030 canal. And then suddenly, everything stops. We 00:38:19.030 --> 00:38:22.050 are entering the territory of dystocia and obstetrical 00:38:22.050 --> 00:38:24.630 emergencies. This is where we move from physiological 00:38:24.630 --> 00:38:27.590 management to mechanical trauma level crisis 00:38:27.590 --> 00:38:30.789 management. Dystocia literally translates to 00:38:30.789 --> 00:38:33.469 difficult, abnormal, or dysfunctional labor. 00:38:33.630 --> 00:38:35.969 Let's set the scene for the most terrifying dystocia 00:38:35.969 --> 00:38:38.789 of all. The patient is pushing. The baby's head 00:38:38.789 --> 00:38:41.289 crowns and delivers. The head is completely out 00:38:41.289 --> 00:38:44.710 in the world. But then, horrifyingly, the head 00:38:44.710 --> 00:38:47.570 pulls back tightly against the mother's perineum. 00:38:48.059 --> 00:38:50.380 What is happening? You are describing the turtle 00:38:50.380 --> 00:38:52.300 sign. It looks exactly like a turtle pulling 00:38:52.300 --> 00:38:54.920 its head back into its shell, and it is the diagnostic 00:38:54.920 --> 00:38:57.340 hallmark of a shoulder dystocia. Why is the head 00:38:57.340 --> 00:38:59.179 pulled back? What is starting? The mechanics 00:38:59.179 --> 00:39:01.619 are brutal. The fetal head successfully navigated 00:39:01.619 --> 00:39:04.099 the pelvis, but the baby's anterior shoulder, 00:39:04.179 --> 00:39:06.639 the shorter facing the ceiling, has become physically 00:39:06.639 --> 00:39:09.199 wedged and locked behind the mother's pubic symphysis, 00:39:09.539 --> 00:39:11.199 the thick bone at the front of the pelvis. So 00:39:11.199 --> 00:39:14.650 it's bone on bone. Exactly. The uterus is contracting, 00:39:14.789 --> 00:39:17.010 trying to push the body out, but the bone is 00:39:17.010 --> 00:39:19.329 acting like a brick wall blocking the shoulder. 00:39:20.030 --> 00:39:22.170 The head pulls back because the neck is being 00:39:22.170 --> 00:39:24.269 stretched tight, but the body can't follow. This 00:39:24.269 --> 00:39:26.550 sounds horrific. Why is this a drop everything 00:39:26.550 --> 00:39:28.989 life or death emergency? Because of the umbilical 00:39:28.989 --> 00:39:31.289 cord? Once the baby's head is out, the umbilical 00:39:31.289 --> 00:39:33.510 cord is dragged down into the birth canal, and 00:39:33.510 --> 00:39:35.789 it is now being severely compressed between the 00:39:35.789 --> 00:39:38.170 baby's stuck body and the mother's pelvis. So 00:39:38.170 --> 00:39:41.260 the cord is crushed. Oh. and the baby can't breathe. 00:39:41.559 --> 00:39:44.219 Right. The baby's head is in the air, but its 00:39:44.219 --> 00:39:46.760 chest is compressed inside the tight birth canal, 00:39:46.800 --> 00:39:49.360 so it cannot expand its lungs to breathe. And 00:39:49.360 --> 00:39:52.000 its oxygen supply from the cord is totally crushed. 00:39:52.460 --> 00:39:54.860 You have roughly five minutes to dislodge that 00:39:54.860 --> 00:39:57.599 shoulder and deliver the baby before profound, 00:39:57.840 --> 00:40:00.420 irreversible hypoxic brain damage occurs. Five 00:40:00.420 --> 00:40:03.659 minutes. OK. You see the turtle sign. You hit 00:40:03.659 --> 00:40:06.199 the emergency call light. The room floods with 00:40:06.199 --> 00:40:09.030 the rapid response team. What are the immediate 00:40:09.030 --> 00:40:11.650 hands -on nursing interventions? The standard 00:40:11.650 --> 00:40:14.150 first -line intervention is the McRoberts maneuver, 00:40:14.530 --> 00:40:17.030 performed simultaneously with suprapubic pressure. 00:40:17.269 --> 00:40:19.670 Walk me through the biomechanics of McRoberts. 00:40:19.989 --> 00:40:22.869 What am I doing to the mother's body? You and 00:40:22.869 --> 00:40:25.230 another nurse grab the mother's legs, remove 00:40:25.230 --> 00:40:27.989 them from the stirrups, and sharply, forcefully 00:40:27.989 --> 00:40:30.309 hyperflex her thighs tightly back against her 00:40:30.309 --> 00:40:34.050 own abdomen. Think knees to nipples. How does 00:40:34.050 --> 00:40:36.610 that unstick a shoulder? It alters the geometry 00:40:36.610 --> 00:40:39.469 of the pelvis. Hyperflexing the legs straightens 00:40:39.469 --> 00:40:42.130 the maternal sacrum and physically rotates the 00:40:42.130 --> 00:40:44.969 pubic symthesis upward, opening the angle of 00:40:44.969 --> 00:40:47.769 the pelvic inlet. Oh, it pivots the bone. Yes. 00:40:48.070 --> 00:40:50.250 It often creates just enough clearance for that 00:40:50.250 --> 00:40:52.070 stuffed shoulder to pop free and slide under 00:40:52.070 --> 00:40:54.530 the bone. But if McRoberts alone doesn't work, 00:40:54.849 --> 00:40:57.409 we add suprapubic pressure. And I know there 00:40:57.409 --> 00:40:59.610 is a deadly exam trap here regarding where you 00:40:59.610 --> 00:41:01.889 push. This is one of the most critical safety 00:41:01.889 --> 00:41:04.969 distinctions you will ever learn. To apply suprapubic 00:41:04.969 --> 00:41:07.650 pressure, you stand on a stool, make a fist, 00:41:08.030 --> 00:41:10.550 and push downward and inward directly over the 00:41:10.550 --> 00:41:12.730 mother's pubic bone, low down on her pelvis. 00:41:12.809 --> 00:41:15.130 Over the pubic bone. Your goal is to physically 00:41:15.130 --> 00:41:17.309 find the baby's stuck shoulder through the skin 00:41:17.309 --> 00:41:19.489 and push it downward, collapsing it so it can 00:41:19.489 --> 00:41:22.429 clear the bone. What happens if a student panics 00:41:22.429 --> 00:41:24.469 and pushes on the top of the mother's stomach 00:41:24.469 --> 00:41:27.010 instead, like up by her ribs? That is called 00:41:27.010 --> 00:41:30.030 fundal pressure, and it is absolutely strictly 00:41:30.030 --> 00:41:33.530 contraindicated during a shoulder dystocia. Why? 00:41:33.769 --> 00:41:36.250 What does it do? If you push on the fundus, the 00:41:36.250 --> 00:41:39.809 top of the uterus, you are applying massive downward 00:41:39.809 --> 00:41:43.170 force onto a baby whose shoulder is firmly wedged 00:41:43.170 --> 00:41:45.909 against a solid bone. You will impact the shoulder 00:41:45.909 --> 00:41:48.090 even tighter. Oh, that makes sense. You're just 00:41:48.090 --> 00:41:50.809 jamming it in. You will cause severe brachial 00:41:50.809 --> 00:41:53.869 plexus nerve injuries, snapping the clavicle, 00:41:54.050 --> 00:41:56.869 and you run a massive risk of physically rupturing 00:41:56.869 --> 00:41:59.309 the mother's uterus from the pressure. Super 00:41:59.309 --> 00:42:02.860 pubic pressure only. Never fundal. That is a 00:42:02.860 --> 00:42:05.280 vivid image to remember. Never push from the 00:42:05.280 --> 00:42:06.900 top when they are stuck at the bottom. Yeah. 00:42:07.019 --> 00:42:09.179 What about other mechanical dystocia like presentation 00:42:09.179 --> 00:42:11.380 issues? Not every baby comes head first. Right. 00:42:11.539 --> 00:42:13.860 A normal presentation is vertex with the chin 00:42:13.860 --> 00:42:17.239 tucked, but many babies are breech, meaning the 00:42:17.239 --> 00:42:19.719 buttocks or the feet are presenting first. What 00:42:19.719 --> 00:42:21.780 are the different flavors of breech? There are 00:42:21.780 --> 00:42:24.380 three main types. Frank breech is the most common. 00:42:24.780 --> 00:42:27.139 The baby's hips are flexed, but their legs are 00:42:27.139 --> 00:42:29.320 extended straight up by their ears, like a diver 00:42:29.320 --> 00:42:31.760 touching their toes. Okay, Frank is folded in 00:42:31.760 --> 00:42:34.079 half. Then there's complete breach, which means 00:42:34.079 --> 00:42:37.059 the baby is sitting cross -legged, Taylor -style, 00:42:37.219 --> 00:42:39.639 right over the cervix. And footling brooch is 00:42:39.639 --> 00:42:42.139 when one or both feet are pointing straight down 00:42:42.139 --> 00:42:44.519 and actually drop into the vagina. Why are we 00:42:44.519 --> 00:42:47.300 so afraid of delivering breech babies vaginally? 00:42:47.500 --> 00:42:49.599 The biggest danger, especially with a footling 00:42:49.599 --> 00:42:51.400 breech, is cord prolapse, which we will cover 00:42:51.400 --> 00:42:54.039 in a moment. But there is also the massive risk 00:42:54.039 --> 00:42:56.460 of head entrapment. Head entrapment. The body 00:42:56.460 --> 00:42:59.119 and legs are smaller than the head. In a breech 00:42:59.119 --> 00:43:01.239 delivery, the body might deliver easily through 00:43:01.239 --> 00:43:03.780 a cervix that is only eight centimeters dilated. 00:43:04.059 --> 00:43:07.400 But then the large hard skull gets to the cervix 00:43:07.400 --> 00:43:10.579 and gets completely stuck. Oh my god. The body 00:43:10.579 --> 00:43:12.380 is out, but the head is trapped. The body is 00:43:12.380 --> 00:43:14.599 out, but the head is trapped inside, compressing 00:43:14.599 --> 00:43:18.460 the cord. It is catastrophic. Most breach presentations 00:43:18.460 --> 00:43:21.559 today are delivered via scheduled cesarean. Is 00:43:21.559 --> 00:43:24.199 there any way to fix a breach presentation before 00:43:24.199 --> 00:43:26.789 labor starts? Like, can we flip them? Providers 00:43:26.789 --> 00:43:29.590 can attempt an external cephalic version, or 00:43:29.590 --> 00:43:33.570 ECV. Around 37 weeks, under ultrasound guidance, 00:43:33.909 --> 00:43:36.050 the provider places their hands firmly on the 00:43:36.050 --> 00:43:38.530 mother's abdomen and physically attempts to roll 00:43:38.530 --> 00:43:40.869 the baby into a head -down position. That sounds 00:43:40.869 --> 00:43:42.969 like it involves a lot of force. It does, and 00:43:42.969 --> 00:43:45.449 it carries risks. It can cause the placenta to 00:43:45.449 --> 00:43:48.130 abrupt or can entangle the umbilical cord, causing 00:43:48.130 --> 00:43:51.090 immediate fetal distress, requiring a crash C 00:43:51.090 --> 00:43:54.409 -section. Is there an exam trap for ECVs? Yes, 00:43:54.530 --> 00:43:57.289 regarding blood typing. The forceful manipulation 00:43:57.289 --> 00:44:00.070 can cause micro -traumas in the placenta, leading 00:44:00.070 --> 00:44:02.389 to a mixing of maternal and fetal blood. Oh, 00:44:02.510 --> 00:44:05.210 the RH factor. Exactly. If the mother has an 00:44:05.210 --> 00:44:07.710 RH negative blood type, this mixing can cause 00:44:07.710 --> 00:44:09.929 her to form antibodies against the baby's blood. 00:44:10.219 --> 00:44:13.000 As a nurse, you must ensure that an Rh -negative 00:44:13.000 --> 00:44:15.639 mother receives a dose of Rh -immunglobulin, 00:44:15.760 --> 00:44:18.519 or ROJAM, whenever an ECV is attempted. Okay, 00:44:18.559 --> 00:44:20.500 we've covered the stuck shoulders and the backwards 00:44:20.500 --> 00:44:23.199 babies. Let's move to the final module, the drop 00:44:23.199 --> 00:44:25.860 -everything emergencies. These are the vascular 00:44:25.860 --> 00:44:28.159 and anatomical disasters where minutes equal 00:44:28.159 --> 00:44:31.599 brain cells or life and death. Let's start with 00:44:31.599 --> 00:44:34.199 the one you just mentioned, prolapsed umbilical 00:44:34.199 --> 00:44:36.880 cord. We've talked about the umbilical cord being 00:44:36.880 --> 00:44:39.219 compressed inside the uterus during variable 00:44:39.219 --> 00:44:43.039 decelerations. A cord prolapse is when the umbilical 00:44:43.039 --> 00:44:45.880 cord physically falls out of the cervix and into 00:44:45.880 --> 00:44:48.360 the vagina ahead of the presenting part of the 00:44:48.360 --> 00:44:51.119 fetus. How does that even happen? It almost always 00:44:51.119 --> 00:44:53.699 happens at the exact moment the amniotic sac 00:44:53.699 --> 00:44:56.239 ruptures when the water breaks. If the baby's 00:44:56.239 --> 00:44:59.000 head is not firmly engaged down in the pelvis, 00:44:59.079 --> 00:45:01.760 if they are at a high negative station, like 00:45:01.760 --> 00:45:04.059 minus three, there is a gap. between the head 00:45:04.059 --> 00:45:06.659 and the cervix. And the fluid just washes it 00:45:06.659 --> 00:45:08.940 out. When the water breaks, the sudden gush of 00:45:08.940 --> 00:45:11.699 fluid washes the slippery umbilical cord down 00:45:11.699 --> 00:45:13.820 through that gap and out the surface. And then 00:45:13.820 --> 00:45:16.079 the heavy bony head descends behind it. Yes. 00:45:16.539 --> 00:45:18.599 The heavy head comes down and pinches the cord 00:45:18.599 --> 00:45:20.760 tightly against the bony walls of the maternal 00:45:20.760 --> 00:45:23.860 pelvis. Blood flow is completely and instantly 00:45:23.860 --> 00:45:26.340 occluded. The baby is literally sitting on his 00:45:26.340 --> 00:45:28.820 own air hose. How do you know this has happened? 00:45:28.989 --> 00:45:31.849 The fetal monitor will instantly show profound 00:45:31.849 --> 00:45:36.090 sustained fetal bradycardia or massive unrecovering 00:45:36.090 --> 00:45:38.989 variable decelerations. The heart rate will crash 00:45:38.989 --> 00:45:41.610 to 60 beats per minute and stay there. That's 00:45:41.610 --> 00:45:44.429 horrifying. Or you might be performing a vaginal 00:45:44.429 --> 00:45:46.889 exam right after the water breaks. And instead 00:45:46.889 --> 00:45:49.670 of feeling a hard, smooth skull, your fingers 00:45:49.670 --> 00:45:53.710 feel a soft pulsating rope -like cord. OK, this 00:45:53.710 --> 00:45:55.710 is where I need to ask a very skeptical question. 00:45:55.980 --> 00:45:58.719 Because my instinct, if an organ is falling out 00:45:58.719 --> 00:46:02.539 of the body, is to put it back in. Do I gently 00:46:02.539 --> 00:46:04.880 push the cord back up into the uterus where it 00:46:04.880 --> 00:46:08.760 belongs? Never. That is a massive exam trap and 00:46:08.760 --> 00:46:11.800 a fatal clinical error. Really? Never. You never, 00:46:11.800 --> 00:46:15.460 ever manipulate, massage, or attempt to stuff 00:46:15.460 --> 00:46:18.619 a prolapsed cord back inside. Handling the umbilical 00:46:18.619 --> 00:46:22.000 cord causes severe vasospasm. The blood vessels 00:46:22.000 --> 00:46:24.059 inside the cord will aggressively clamp shut 00:46:24.059 --> 00:46:26.320 from the irritation, permanently cutting off 00:46:26.320 --> 00:46:28.519 whatever tiny amount of oxygen was still flowing. 00:46:28.760 --> 00:46:30.880 Okay, so I don't touch the cord, what do I do? 00:46:31.019 --> 00:46:33.039 Your hand is already in the vagina from the exam, 00:46:33.280 --> 00:46:35.619 you keep it there. You take your sterile gloved 00:46:35.619 --> 00:46:37.980 fingers, you find the baby's hard skull, and 00:46:37.980 --> 00:46:40.920 you push it firmly UP toward the ceiling. Wait, 00:46:40.920 --> 00:46:42.980 you want me to push the baby back in? You are 00:46:42.980 --> 00:46:45.619 manually lifting the heavy fetal head off the 00:46:45.619 --> 00:46:48.159 umbilical cord, creating space for blood to flow. 00:46:48.400 --> 00:46:50.579 So I literally hold the baby's head up inside 00:46:50.579 --> 00:46:54.119 the mother? Yes. And you do not remove your hand. 00:46:54.559 --> 00:46:57.340 You stay in that extremely awkward, physically 00:46:57.340 --> 00:46:59.360 exhausting position while you yell for help, 00:46:59.420 --> 00:47:01.619 while the team rushes in, while they move the 00:47:01.619 --> 00:47:03.739 mother to a stretcher, and you literally ride 00:47:03.739 --> 00:47:05.719 on the bed with your hand inside the patient 00:47:05.719 --> 00:47:08.119 all the way to the operating room. Oh, man. You 00:47:08.119 --> 00:47:10.460 stay there until the surgeon makes the abdominal 00:47:10.460 --> 00:47:13.360 incision and pulls the baby out from above. You 00:47:13.360 --> 00:47:16.179 are the physical bridge keeping that baby alive. 00:47:16.420 --> 00:47:19.059 That is absolutely wild. And it highlights how 00:47:19.059 --> 00:47:21.539 critical the nursing role is. What else are we 00:47:21.539 --> 00:47:24.000 doing to help gravity? You want gravity to pull 00:47:24.000 --> 00:47:26.119 the baby away from the pelvis. You immediately 00:47:26.119 --> 00:47:28.960 reposition the mother into an extreme knee chest 00:47:28.960 --> 00:47:31.340 position. Knee chest. Where she is on her hands 00:47:31.340 --> 00:47:33.460 and knees with her chest resting on the mattress. 00:47:33.980 --> 00:47:36.599 Or you put her into steep Trendelenburg where 00:47:36.599 --> 00:47:38.380 the head of the bed head is tilted drastically 00:47:38.380 --> 00:47:40.860 down and her hips are elevated. Okay, that is 00:47:40.860 --> 00:47:45.199 cord prolapse. Head UP, hips UP. What is the 00:47:45.199 --> 00:47:48.599 next major emergency? Uterine rupture. This is 00:47:48.599 --> 00:47:50.960 the catastrophic tearing apart of the muscular 00:47:50.960 --> 00:47:53.659 layers of the uterus. The structural integrity 00:47:53.659 --> 00:47:56.400 of the organ fails. The uterus just rips open. 00:47:56.570 --> 00:48:00.909 Yes. The amniotic fluid, the placenta, and sometimes 00:48:00.909 --> 00:48:03.849 the entire fetus itself can be expelled out of 00:48:03.849 --> 00:48:06.750 the torn uterus directly into the maternal abdominal 00:48:06.750 --> 00:48:08.429 cavity. That sounds like something out of a horror 00:48:08.429 --> 00:48:10.849 movie. Yeah. Who is at risk for their uterus 00:48:10.849 --> 00:48:13.469 just tearing open? In the United States, the 00:48:13.469 --> 00:48:16.349 single greatest risk factor is a scarred uterus 00:48:16.349 --> 00:48:19.889 from a previous cesarean section. Ah, the scar 00:48:19.889 --> 00:48:23.130 tissue. Right. When a woman opts for a TOLAC, 00:48:23.289 --> 00:48:26.530 a trial of labor, After cesarean attempting a 00:48:26.530 --> 00:48:29.010 vaginal birth, she is monitored continuously 00:48:29.010 --> 00:48:32.030 specifically for this risk. The old surgical 00:48:32.030 --> 00:48:34.809 scar on the uterus is the weakest point. So if 00:48:34.809 --> 00:48:37.010 contractions get too strong? If the uterus is 00:48:37.010 --> 00:48:39.730 hyper stimulated, perhaps by aggressive doses 00:48:39.730 --> 00:48:42.150 of pedicine driving contractions too hard and 00:48:42.150 --> 00:48:44.829 too fast, that scar tissue can just give way 00:48:44.829 --> 00:48:47.210 under the immense pressure. How do you spot a 00:48:47.210 --> 00:48:49.309 rupture before it's too late? What are the clinical 00:48:49.309 --> 00:48:51.710 signs? It is sudden and violent. The classic 00:48:51.710 --> 00:48:54.449 presentation is the patient screaming in acute, 00:48:54.809 --> 00:48:57.730 severe, tearing abdominal pain that is distinctly 00:48:57.730 --> 00:48:59.550 different from her contraction pain. In the monitor? 00:48:59.869 --> 00:49:02.309 On the monitor, you will see a sudden loss of 00:49:02.309 --> 00:49:04.829 uterine tone. The rhythmic contraction mountains 00:49:04.829 --> 00:49:07.710 just disappear into a flat line because the torn 00:49:07.710 --> 00:49:10.670 muscle can no longer contract. The fetal heart 00:49:10.670 --> 00:49:13.150 rate will crash into profound bradycardia as 00:49:13.150 --> 00:49:15.130 the placenta shears off. And what happens to 00:49:15.130 --> 00:49:17.199 the physical exam? Yeah. Where is the baby? This 00:49:17.199 --> 00:49:20.699 is a highly testable finding. A sudden loss of 00:49:20.699 --> 00:49:22.840 fetal station. Loss of station. If you checked 00:49:22.840 --> 00:49:25.519 her 10 minutes ago and the baby was at plus two 00:49:25.519 --> 00:49:28.539 station deep in the pelvis and now she is in 00:49:28.539 --> 00:49:30.900 agonizing pain and you check again and you can't 00:49:30.900 --> 00:49:34.059 feel the head at all, the baby has slipped back 00:49:34.059 --> 00:49:36.619 up and out of the torn uterus into the abdomen. 00:49:37.039 --> 00:49:39.239 Sudden pain, flat contractions, baby disappears. 00:49:39.880 --> 00:49:42.539 What is the intervention? Immediate crash laparotomy 00:49:42.539 --> 00:49:45.480 in cesarean. Your role is prepping for massive 00:49:45.480 --> 00:49:48.079 maternal hemorrhagic shock. You need two large 00:49:48.079 --> 00:49:51.440 -bore IVs, 18 gauge or larger, pumping in rapid 00:49:51.440 --> 00:49:53.719 fluid resuscitation and preparing for massive 00:49:53.719 --> 00:49:56.300 blood transfusions. The mother is bleeding out 00:49:56.300 --> 00:49:58.400 internally, and the baby is suffocating. Which 00:49:58.400 --> 00:50:00.320 brings us to the final emergency, which also 00:50:00.320 --> 00:50:02.619 involves massive bleeding. Placental abruption, 00:50:03.260 --> 00:50:06.679 or a placenta? Yes. The placenta is supposed 00:50:06.679 --> 00:50:09.099 to remain firmly attached to the uterine wall 00:50:09.099 --> 00:50:12.079 until stage three of labor, after the baby is 00:50:12.079 --> 00:50:15.099 born. An abruption is the premature separation 00:50:15.099 --> 00:50:17.260 of the placenta from the uterine wall while the 00:50:17.260 --> 00:50:19.880 baby is still inside. It just tears away. It 00:50:19.880 --> 00:50:22.659 can be a partial separation at the edges or a 00:50:22.659 --> 00:50:25.760 complete devastating separation. When the placenta 00:50:25.760 --> 00:50:28.619 tears away, what is the immediate consequence? 00:50:28.860 --> 00:50:31.500 Two things happen simultaneously. First, the 00:50:31.500 --> 00:50:33.659 area of the placenta that detached is no longer 00:50:33.659 --> 00:50:36.960 exchanging oxygen, so the fetus instantly experiences 00:50:36.960 --> 00:50:40.500 hypoxia, leading to late decelerations or bradycardia. 00:50:40.699 --> 00:50:43.340 And the second. Second, the maternal spiral arteries 00:50:43.340 --> 00:50:45.360 that were feeding that placenta are now sheared 00:50:45.360 --> 00:50:48.679 open and bleeding massively. But I've heard that 00:50:48.679 --> 00:50:50.659 sometimes with an abruption, you don't even see 00:50:50.659 --> 00:50:54.219 any blood. How is that possible? That is a crucial 00:50:54.219 --> 00:50:56.219 distinction. It depends on where the placenta 00:50:56.219 --> 00:50:58.559 separates. If it separates at the edges, the 00:50:58.559 --> 00:51:00.780 blood flows down past the membranes and out the 00:51:00.780 --> 00:51:04.340 cervix, presenting as visible, dark, red, vaginal 00:51:04.340 --> 00:51:06.940 bleeding. But if it's not at the edges? If it 00:51:06.940 --> 00:51:08.900 separates directly in the center, the edges remain 00:51:08.900 --> 00:51:11.699 sealed to the uterine wall. The blood pumps out 00:51:11.699 --> 00:51:14.420 and pools behind the placenta, creating a massive 00:51:14.420 --> 00:51:17.500 retroplacental hematoma. Oh, a concealed hemorrhage. 00:51:17.679 --> 00:51:20.760 Exactly. The mother could lose a liter of blood 00:51:20.760 --> 00:51:23.000 into her uterus and you wouldn't see a drop on 00:51:23.000 --> 00:51:25.900 the bedsheets. That is terrifying. If I can't 00:51:25.900 --> 00:51:27.460 see the blood, how do I know it's happening? 00:51:27.679 --> 00:51:31.219 Pain and rigidity. As the blood fills the enclosed 00:51:31.219 --> 00:51:33.400 space of the uterine muscle, it irritates the 00:51:33.400 --> 00:51:36.440 myometrium, causing continuous, severe, knife 00:51:36.440 --> 00:51:39.139 -like abdominal pain. So it hurts continuously, 00:51:39.480 --> 00:51:42.260 not just during a contraction. Right. And the 00:51:42.260 --> 00:51:45.079 uterus becomes hypertonic. It refuses to relax. 00:51:45.340 --> 00:51:47.480 If you palpate the mother's abdomen, it will 00:51:47.480 --> 00:51:50.619 feel rock hard, rigid, and board -like. A rigid, 00:51:50.840 --> 00:51:53.340 board -like abdomen. That is a massive red flag. 00:51:53.519 --> 00:51:55.940 It is the classic clinical sign of a severe abruption. 00:51:56.400 --> 00:51:59.659 The treatment is the same as a rupture. hemodynamic 00:51:59.659 --> 00:52:03.099 support, oxygen, and an immediate emergency cesarean 00:52:03.099 --> 00:52:05.119 to save the baby and stop the bleeding. Okay, 00:52:05.659 --> 00:52:08.260 we have covered an incredible, intense amount 00:52:08.260 --> 00:52:11.199 of ground today. From the calm baseline of a 00:52:11.199 --> 00:52:13.860 normal dashboard, down the steep cliffs of decelerations, 00:52:14.179 --> 00:52:16.719 and into the absolute chaos of prolapsed cords 00:52:16.719 --> 00:52:19.739 and ruptures. What strikes me is how interconnected 00:52:19.739 --> 00:52:21.980 all of this is. It's all connected. You can't 00:52:21.980 --> 00:52:24.420 understand a late deceleration if you don't understand 00:52:24.420 --> 00:52:27.480 placental perfusion. You can't understand a shoulder 00:52:27.480 --> 00:52:29.800 dystocia if you don't understand the anatomy 00:52:29.800 --> 00:52:32.300 of the maternal pelvis. And that is exactly what 00:52:32.300 --> 00:52:34.380 the NCLE -X and your clinical instructors are 00:52:34.380 --> 00:52:36.670 testing. They are not testing your ability to 00:52:36.670 --> 00:52:38.869 just regurgitate a definition. They are testing 00:52:38.869 --> 00:52:41.590 your clinical judgment. Can you look at a rigid 00:52:41.590 --> 00:52:44.650 abdomen and a crashing fetal heart rate, recognize 00:52:44.650 --> 00:52:47.369 the pattern of an abruption, understand the underlying 00:52:47.369 --> 00:52:50.429 physiology of hemorrhagic shock, and prioritize 00:52:50.429 --> 00:52:52.889 your actions to start an IV and prep the OR? 00:52:53.329 --> 00:52:55.730 That is what makes you a safe nurse. Before we 00:52:55.730 --> 00:52:58.289 sign off, I want to pivot slightly. We spent 00:52:58.289 --> 00:53:01.170 this entire hour hyper -focused on the physical 00:53:01.170 --> 00:53:03.809 interventions, the clued boluses, the oxygen 00:53:03.809 --> 00:53:07.230 masks, the McRoberts maneuver, the raw mechanics 00:53:07.230 --> 00:53:10.130 of saving a life. But there is another layer 00:53:10.130 --> 00:53:12.130 to this that often gets lost in the adrenaline. 00:53:12.349 --> 00:53:15.750 The psychological impact? Yes. I want you, the 00:53:15.750 --> 00:53:18.650 listener, to pause and consider the psychological 00:53:18.650 --> 00:53:21.989 trauma of a stat crash c -section or a severe 00:53:21.989 --> 00:53:24.969 postpartum hemorrhage. Think about the patient's 00:53:24.969 --> 00:53:27.610 perspective. She came in with a birth plan. Maybe 00:53:27.610 --> 00:53:29.710 she had soft music playing and dim lighting. 00:53:30.289 --> 00:53:32.849 She was expecting a beautiful natural transition 00:53:32.849 --> 00:53:35.110 to motherhood. And in the span of 60 seconds, 00:53:35.250 --> 00:53:38.110 her reality shatters and alarm sounds. A dozen 00:53:38.110 --> 00:53:40.210 strangers and scrubs sprint into her room. The 00:53:40.210 --> 00:53:42.389 lights are thrown on. Someone yells, cord prolapse. 00:53:42.510 --> 00:53:44.989 It's pure chaos. You leap onto her bed and insert 00:53:44.989 --> 00:53:47.269 your hand into her body. She's thrown onto a 00:53:47.269 --> 00:53:49.110 gurney, sprinted down a hallway, strapped to 00:53:49.110 --> 00:53:51.530 an operating table, and put to sleep under general 00:53:51.530 --> 00:53:53.570 anesthesia before she can even ask if her baby 00:53:53.570 --> 00:53:57.050 is going to die. It is an acute, profound psychological 00:53:57.050 --> 00:54:00.369 crisis. And surviving the physical emergency 00:54:00.369 --> 00:54:03.170 is only step one. The challenge I want to leave 00:54:03.170 --> 00:54:05.250 you with to mull over as you prepare for your 00:54:05.250 --> 00:54:09.530 career is this. As a future nurse, you are the 00:54:09.530 --> 00:54:12.190 face of that trauma. You really are. How will 00:54:12.190 --> 00:54:14.489 your communication, your eye contact, your tone 00:54:14.489 --> 00:54:17.309 of voice, and your calm, authoritative presence 00:54:17.309 --> 00:54:20.909 in those frantic, terrifying 10 minutes alter 00:54:20.909 --> 00:54:22.989 that patient's mental health recovery for the 00:54:22.989 --> 00:54:25.750 next 10 years? It's a powerful question. A technician 00:54:25.750 --> 00:54:29.079 can start a large borvée. A truly excellent nurse 00:54:29.079 --> 00:54:32.079 manages the physical pathophysiology while fiercely 00:54:32.079 --> 00:54:34.280 protecting the patient's dignity, validating 00:54:34.280 --> 00:54:36.460 her fear and providing a sense of psychological 00:54:36.460 --> 00:54:39.320 safety even in the midst of absolute chaos. Even 00:54:39.320 --> 00:54:41.059 if it's just looking her in the eye as they wheel 00:54:41.059 --> 00:54:43.199 her down the hall and saying, I am right here 00:54:43.199 --> 00:54:44.920 with you and we're going to take care of your 00:54:44.920 --> 00:54:47.519 baby. That is the art of nursing layered right 00:54:47.519 --> 00:54:50.039 over the science. Well said. To all the nursing 00:54:50.039 --> 00:54:52.400 students out there, take a deep breath. Review 00:54:52.400 --> 00:54:54.980 these physiological patterns. Trust your training. 00:54:55.440 --> 00:54:58.079 Remember that behind every alarm is a physical 00:54:58.079 --> 00:55:00.320 mechanism you can understand, and behind every 00:55:00.320 --> 00:55:02.539 patient is a human being looking to you for safety. 00:55:02.900 --> 00:55:05.559 Go confidently tackle those exams and your clinicals. 00:55:05.739 --> 00:55:07.760 You've got this. We'll see you on the next Deep 00:55:07.760 --> 00:55:08.039 Dive.
