WEBVTT 00:00:07.880 --> 00:00:10.759 You're in the bay. Once you get over to the bed, 00:00:10.919 --> 00:00:13.560 we'll give you the story. Everything's going 00:00:13.560 --> 00:00:17.339 to happen super fast. Welcome to the emergency 00:00:17.339 --> 00:00:45.060 room. So worldwide, one woman dies every four 00:00:45.060 --> 00:00:47.270 minutes from post -cardiom hemorrhage. Yeah, 00:00:47.270 --> 00:00:50.090 it is a staggering statistic. I mean, that's 00:00:50.090 --> 00:00:53.369 140 ,000 maternal deaths every single year. Right. 00:00:53.829 --> 00:00:57.049 And it is a catastrophic emergency that, you 00:00:57.049 --> 00:00:59.649 know, often strikes with absolutely zero warning, 00:01:00.009 --> 00:01:02.950 like in patients with no risk factors at all, 00:01:03.250 --> 00:01:06.010 right after perfectly normal deliveries. Exactly. 00:01:06.209 --> 00:01:08.569 And when it happens, you, the bedside nurse, 00:01:08.629 --> 00:01:10.890 you are literally the only thing standing between 00:01:10.890 --> 00:01:13.510 your patient and a fatal outcome. Yeah, that 00:01:13.510 --> 00:01:15.790 is the intense reality of the delivery room. 00:01:15.870 --> 00:01:18.370 It is. And you know, it's why today we aren't 00:01:18.370 --> 00:01:21.049 just casually reviewing obstetric texts. I am 00:01:21.049 --> 00:01:23.269 stepping into the role of your clinical mentor 00:01:23.269 --> 00:01:25.810 today and we are treating this as an intensive, 00:01:26.129 --> 00:01:28.170 high stakes coaching session. Right. We are talking 00:01:28.170 --> 00:01:31.129 directly to you, the future nurse, the future 00:01:31.129 --> 00:01:32.750 colleague who is going to be standing at the 00:01:32.750 --> 00:01:35.390 foot of that bed. Because right now you might 00:01:35.390 --> 00:01:38.569 be staring down a massive stack of OB textbooks. 00:01:38.650 --> 00:01:40.650 Oh, for sure. Feeling like you have to memorize 00:01:40.650 --> 00:01:43.109 just like a million isolated facts just to pass 00:01:43.109 --> 00:01:46.620 your exams. But we are going to the Pareto principle 00:01:46.620 --> 00:01:49.540 aggressively today. We are sifting through all 00:01:49.540 --> 00:01:53.680 that noise to find that core 20 % of concepts 00:01:53.680 --> 00:01:55.819 that will give you 80 % of the value. Right on 00:01:55.819 --> 00:01:58.599 your nursing exams and obviously in your actual 00:01:58.599 --> 00:02:01.239 clinical practice. Absolutely and postpartum 00:02:01.239 --> 00:02:05.019 hemorrhage or PPH is the ultimate high yield 00:02:05.019 --> 00:02:08.060 never miss emergency. It is the absolute priority 00:02:08.060 --> 00:02:11.370 because obstetrics is so dynamic. Oh, incredibly 00:02:11.370 --> 00:02:13.830 dynamic. One minute you are helping a mother 00:02:13.830 --> 00:02:16.509 initiate skin -to -skin contact, and the very 00:02:16.509 --> 00:02:19.770 next minute you are initiating a massive transfusion 00:02:19.770 --> 00:02:21.979 protocol. Yeah, things change in an instant. 00:02:22.159 --> 00:02:24.300 And to understand why it happened so fast, you 00:02:24.300 --> 00:02:26.800 really have to understand the anatomy. OK, let's 00:02:26.800 --> 00:02:28.900 get into it. I want you to visualize the post 00:02:28.900 --> 00:02:32.340 -delivery uterus. Think of it as a massive, intricate, 00:02:32.919 --> 00:02:35.039 muscular tourniquet. Right, let's unpack that. 00:02:35.139 --> 00:02:38.080 Because before I really dove into this material, 00:02:38.520 --> 00:02:40.719 I always sort of vaguely thought of bleeding 00:02:40.719 --> 00:02:43.840 after birth as just, well, normal. Sure, a lot 00:02:43.840 --> 00:02:45.780 of people think that. Like, of course there's 00:02:45.780 --> 00:02:48.419 bleeding. A baby just came out. But when the 00:02:48.419 --> 00:02:51.039 placenta detaches from the uterine wall, it's 00:02:51.039 --> 00:02:53.819 not just a little scrape. Cut at all. It leaves 00:02:53.819 --> 00:02:57.879 behind this massive open wound full of sheared 00:02:57.879 --> 00:03:01.439 -off, massively dilated maternal blood vessels, 00:03:01.639 --> 00:03:05.300 right? The spiral arteries. Exactly. During pregnancy, 00:03:05.860 --> 00:03:08.479 those spiral arteries dilate significantly. I 00:03:08.479 --> 00:03:11.969 mean, they have to. pump an enormous volume of 00:03:11.969 --> 00:03:14.270 blood to the placenta. Wow, okay. So once the 00:03:14.270 --> 00:03:16.169 placenta is delivered, you have these wide open 00:03:16.169 --> 00:03:18.330 vessels just pumping blood straight into the 00:03:18.330 --> 00:03:20.629 uterine cavity. And if you relied solely on your 00:03:20.629 --> 00:03:23.150 body's normal clotting cascade, like platelets 00:03:23.150 --> 00:03:26.150 and fibrin, just trying to plug the holes? The 00:03:26.150 --> 00:03:28.449 patient would bleed to death before a clot could 00:03:28.449 --> 00:03:31.430 ever form. Seriously? Yeah, simply too high. 00:03:31.949 --> 00:03:35.129 So to survive, the uterine muscle itself has 00:03:35.129 --> 00:03:38.490 to literally clamp down. It physically strangles 00:03:38.490 --> 00:03:41.050 those arteries shut. Oh, wow. So that is the 00:03:41.050 --> 00:03:42.669 tourniquet. That's the tourniquet. Yeah. And 00:03:42.669 --> 00:03:45.550 when that muscular tourniquet fails to tighten 00:03:45.550 --> 00:03:47.889 or something physically prevents it from tightening, 00:03:48.229 --> 00:03:50.849 things go south incredibly fast, which gives 00:03:50.849 --> 00:03:53.689 us our logical progression for this clinical 00:03:53.689 --> 00:03:56.310 deep dive. Right. First, we need to know exactly 00:03:56.310 --> 00:03:59.110 how to recognize the crisis, right? Like what 00:03:59.110 --> 00:04:02.009 hypovolemia actually looks like in a postpartum 00:04:02.009 --> 00:04:03.750 patient. Because they don't show it the way a 00:04:03.750 --> 00:04:07.580 normal trauma patient might. Exactly. Then, we're 00:04:07.580 --> 00:04:09.659 gonna talk about how to fix the broken clamp 00:04:09.659 --> 00:04:12.460 itself, which is uterine atony. Yep, the number 00:04:12.460 --> 00:04:14.960 one cause. From there, we'll search for the physical 00:04:14.960 --> 00:04:17.519 blockers to get in the way of that clamp, things 00:04:17.519 --> 00:04:20.220 like routine tissue or trauma. And finally, we 00:04:20.220 --> 00:04:22.879 will look at the absolute nightmare scenarios. 00:04:23.019 --> 00:04:25.740 Right. Managing total systemic and structural 00:04:25.740 --> 00:04:28.579 collapse. So let's jump straight into recognizing 00:04:28.579 --> 00:04:31.139 the crisis. Yeah. And here is where it gets scary. 00:04:31.420 --> 00:04:33.660 And honestly, where your exams will actively 00:04:33.660 --> 00:04:35.860 try to trick you. Oh, they love to test this. 00:04:36.019 --> 00:04:39.860 The text makes a massive point that PPH is not 00:04:39.860 --> 00:04:43.319 a disease in itself. It is a clinical sign. Right. 00:04:43.740 --> 00:04:47.079 And it frequently occurs in a completely uncomplicated 00:04:47.079 --> 00:04:50.350 pregnancy. You absolutely cannot look at a healthy 00:04:50.350 --> 00:04:52.649 25 -year -old first -time mom and think, well, 00:04:52.709 --> 00:04:54.730 she's low risk. I don't need to monitor hers 00:04:54.730 --> 00:04:58.209 closely. No. Vigilance is your absolute core 00:04:58.209 --> 00:05:01.290 nursing duty. The moment you let your guard down 00:05:01.290 --> 00:05:04.250 is the exact moment you miss the window for early 00:05:04.250 --> 00:05:06.930 intervention. So true. So let's define what we 00:05:06.930 --> 00:05:08.810 are actually looking for here. The definition 00:05:08.810 --> 00:05:11.269 of postpartum hemorrhage has actually undergone 00:05:11.269 --> 00:05:13.930 a pretty major evolution recently. Yeah. And 00:05:13.930 --> 00:05:16.589 this is highly testable, guys. Definitely. You 00:05:16.589 --> 00:05:20.769 might have heard older nurses or Outdated prep 00:05:20.769 --> 00:05:23.670 materials talk about the 500 -milliliter rule 00:05:23.670 --> 00:05:26.350 for a vaginal delivery. Right. And the 1 ,000 00:05:26.350 --> 00:05:29.029 -milliliter rule for a cesarean. Exactly. But 00:05:29.029 --> 00:05:31.589 the ACOG Revitalize program completely shifted 00:05:31.589 --> 00:05:34.329 that paradigm. You need to know the modern high 00:05:34.329 --> 00:05:36.990 -yield definition. Okay, lay it on us. Today, 00:05:37.250 --> 00:05:39.750 PPH is defined as a cumulative blood loss of 00:05:39.750 --> 00:05:42.550 1 ,000 milliliters or greater, regardless of 00:05:42.550 --> 00:05:44.410 the route of delivery. Okay, so it doesn't matter 00:05:44.410 --> 00:05:47.050 if it was vaginal or surgical. 1 ,000 is the 00:05:47.050 --> 00:05:49.920 new benchmark line. Right, but wait, there is 00:05:49.920 --> 00:05:52.560 a massive caveat to that rule in the text. Yes, 00:05:52.819 --> 00:05:55.680 the Orr Clause. Exactly. It's not just about 00:05:55.680 --> 00:05:58.800 the 1 ,000 milliliters. It is 1 ,000 milliliters 00:05:58.800 --> 00:06:01.879 or R, any amount of blood loss accompanied by 00:06:01.879 --> 00:06:04.899 signs or symptoms of hypovolemia within 24 hours 00:06:04.899 --> 00:06:07.959 of delivery. And that or is just the most important 00:06:07.959 --> 00:06:10.519 word in the definition. Absolutely. If a patient 00:06:10.519 --> 00:06:14.040 loses 600 milliliters but she is showing signs 00:06:14.040 --> 00:06:17.120 of hypovolemic shock, she is having a postpartum 00:06:17.120 --> 00:06:20.389 hemorrhage. Period. We treat the patient, not 00:06:20.389 --> 00:06:22.769 just the number on the scale. Precisely. Okay. 00:06:22.870 --> 00:06:25.089 And just to clarify terminology for the exams, 00:06:25.509 --> 00:06:28.370 we separate this into primary and secondary hemorrhage. 00:06:28.689 --> 00:06:31.490 Right. Primary or early PPH happens within the 00:06:31.490 --> 00:06:34.290 first 24 hours after delivery. And secondary 00:06:34.290 --> 00:06:37.870 or delayed PPH happens after that first 24 hours, 00:06:38.149 --> 00:06:40.620 all the way up to 12 weeks postpartum. Clinically, 00:06:40.720 --> 00:06:43.160 you need to know that primary PPH is far more 00:06:43.160 --> 00:06:46.160 common and generally much more severe. That first 00:06:46.160 --> 00:06:48.819 24 -hour window is really the danger zone. Yes, 00:06:48.819 --> 00:06:51.560 it is. Now, even though we just established that 00:06:51.560 --> 00:06:54.360 PPH can happen to anyone without warning, there 00:06:54.360 --> 00:06:57.139 are risk factors you must identify upon admission 00:06:57.139 --> 00:06:59.480 to the labor unit. Because this helps you anticipate 00:06:59.480 --> 00:07:02.259 and prepare, right? Exactly. So let's break some 00:07:02.259 --> 00:07:04.060 of those down, because exams love to give you 00:07:04.060 --> 00:07:06.759 a patient profile and ask, you know, which patient 00:07:06.759 --> 00:07:10.100 is at highest risk for PPH. Oh, constantly. The 00:07:10.100 --> 00:07:12.699 text lists a prolonged labor, augmented labor, 00:07:13.000 --> 00:07:15.480 like using Peterson to force contractions, or 00:07:15.480 --> 00:07:18.139 a very rapid, precipitous labor. I want you to 00:07:18.139 --> 00:07:20.300 stop and think about the why behind those labor 00:07:20.300 --> 00:07:24.019 patterns. Okay. The uterus is a muscle. If a 00:07:24.019 --> 00:07:27.339 mother labors for 36 hours, that muscle has been 00:07:27.339 --> 00:07:29.699 contracting and working for a day and a half. 00:07:29.759 --> 00:07:33.519 Wow, yeah. It has to be exhausted. It is entirely 00:07:33.519 --> 00:07:35.639 exhausted. By the time the baby and placenta 00:07:35.639 --> 00:07:38.079 are out, that muscle just wants to relax. It 00:07:38.079 --> 00:07:40.019 doesn't have the energy left to form that tight 00:07:40.019 --> 00:07:42.680 tourniquet. That makes total sense. And conversely, 00:07:42.720 --> 00:07:45.060 in a rapid precipitous labor. In a precipitous 00:07:45.060 --> 00:07:47.420 labor, the muscle contracts so violently and 00:07:47.420 --> 00:07:49.420 forcefully that it essentially short circuits. 00:07:49.759 --> 00:07:51.759 It wears itself out in three hours instead of 00:07:51.759 --> 00:07:54.240 12. OK, so either way, muscle fatigue is the 00:07:54.240 --> 00:07:56.399 enemy. Exactly. And the same goes for an over 00:07:56.399 --> 00:07:58.519 -destended uterus. Right, like if a patient is 00:07:58.519 --> 00:08:01.540 carrying twins or a macrosonic baby. a very large 00:08:01.540 --> 00:08:05.100 baby, or has excess amniotic fluid. Yep, that 00:08:05.100 --> 00:08:07.459 uterine muscle gets stretched way beyond its 00:08:07.459 --> 00:08:09.579 normal capacity. Like an old rubber band that 00:08:09.579 --> 00:08:11.819 has been pulled too tight for too long. That's 00:08:11.819 --> 00:08:14.500 a great analogy. It loses its elasticity and 00:08:14.500 --> 00:08:17.860 just fails to snap back. Okay, got it. What are 00:08:17.860 --> 00:08:20.240 some other key risk factors? You want to watch 00:08:20.240 --> 00:08:23.720 for a history of previous postpartum hemorrhage, 00:08:24.040 --> 00:08:27.139 hypertensive disorders like preeclampsia, and 00:08:27.139 --> 00:08:30.360 operative deliveries using forceps or vacuums. 00:08:30.540 --> 00:08:33.379 And the text also mentions intraamniotic infection, 00:08:33.860 --> 00:08:36.659 commonly known as chorioamnionitis. Yes! Hold 00:08:36.659 --> 00:08:38.960 on, let's define chorioamnionitis for someone 00:08:38.960 --> 00:08:41.840 who might be blanking on their terminology during 00:08:41.840 --> 00:08:44.419 a stressful shift. Good idea. That's an infection 00:08:44.419 --> 00:08:46.519 of the amniotic fluid and the fetal membrane. 00:08:46.820 --> 00:08:48.399 Right. And if you think about what infection 00:08:48.399 --> 00:08:50.379 and inflammation do to muscle tissue anywhere 00:08:50.379 --> 00:08:53.259 in the body, it impairs its function. Exactly. 00:08:53.639 --> 00:08:55.840 An infected inflamed uterus is simply not going 00:08:55.840 --> 00:08:58.460 to contract efficiently. OK. So we know the definition. 00:08:58.580 --> 00:09:01.620 And we know who is at risk. But why does this 00:09:01.620 --> 00:09:03.679 matter so much? Well, obviously, bleeding to 00:09:03.679 --> 00:09:06.159 death is bad. Right. Obviously. But the text 00:09:06.159 --> 00:09:09.460 emphasizes that PPH isn't just about the volume 00:09:09.460 --> 00:09:12.480 of blood pooling on the floor. It is about the 00:09:12.480 --> 00:09:15.779 patient surviving the catastrophic sequelae. 00:09:15.919 --> 00:09:17.779 The aftereffects of losing that much volume. 00:09:18.059 --> 00:09:20.500 This is a crucial concept for prioritization 00:09:20.500 --> 00:09:22.779 questions. Because if a patient survives the 00:09:22.779 --> 00:09:25.379 initial hemorrhage, they're not necessarily out 00:09:25.379 --> 00:09:28.600 of the woods. Not at all. Profound hypovolemia 00:09:28.600 --> 00:09:31.620 starves the entire body of oxygen. This leads 00:09:31.620 --> 00:09:34.659 to severe morbidities like adult respiratory 00:09:34.659 --> 00:09:38.539 distress syndrome. or ARDS. Wow. It causes profound 00:09:38.539 --> 00:09:41.139 shock and it can cause something called Sheehan 00:09:41.139 --> 00:09:43.120 syndrome. Sheehan syndrome. Let's talk about 00:09:43.120 --> 00:09:44.879 that because it sounds absolutely terrifying. 00:09:44.960 --> 00:09:47.759 It is. The blood loss and the drop in blood pressure 00:09:47.759 --> 00:09:51.019 are so extreme that the pituitary gland in the 00:09:51.019 --> 00:09:54.440 brain literally starves for oxygen. and undergoes 00:09:54.440 --> 00:09:57.000 necrosis, it dies. And the pituitary gland is 00:09:57.000 --> 00:09:59.019 the master control center for your hormones. 00:09:59.120 --> 00:10:01.679 Right. If it dies, the patient loses the ability 00:10:01.679 --> 00:10:03.539 to produce breast milk, their menstrual cycle 00:10:03.539 --> 00:10:06.539 won't return, and they suffer from lifelong endocrine 00:10:06.539 --> 00:10:08.960 failure. That is permanent life altering damage. 00:10:09.039 --> 00:10:11.019 Which is exactly what we are trying to prevent. 00:10:11.379 --> 00:10:14.019 Okay, so as a nurse, my job is to catch this 00:10:14.019 --> 00:10:16.019 before it gets anywhere near that point. Yes. 00:10:16.250 --> 00:10:18.429 Which means you need to be able to look at your 00:10:18.429 --> 00:10:21.029 patient and clearly separate what is expected 00:10:21.029 --> 00:10:23.370 from what is concerning. Because again, pregnant 00:10:23.370 --> 00:10:25.970 bodies adapt. What is an expected presentation 00:10:25.970 --> 00:10:28.970 after birth? An expected presentation is a healthy 00:10:28.970 --> 00:10:32.110 patient who is tolerating a normal blood volume 00:10:32.110 --> 00:10:35.809 loss. Over the course of pregnancy, a mother's 00:10:35.809 --> 00:10:38.490 blood volume naturally expands by about 40 to 00:10:38.490 --> 00:10:40.990 50 percent. Wow, that's a lot. She essentially 00:10:40.990 --> 00:10:44.389 builds up a massive reserve tank precisely to 00:10:44.389 --> 00:10:46.590 tolerate the bleeding of childbirth. OK, so if 00:10:46.590 --> 00:10:49.190 she loses a normal amount of blood, she will 00:10:49.190 --> 00:10:52.990 have absolutely zero signs or symptoms of hypovolemia. 00:10:53.149 --> 00:10:55.320 Right. Her heart rate will be normal, her blood 00:10:55.320 --> 00:10:57.159 pressure will be normal, her skin will be warm 00:10:57.159 --> 00:10:59.980 and dry. But the concerning presentation, what 00:10:59.980 --> 00:11:02.840 the text outlines is the hypovolemia escalation 00:11:02.840 --> 00:11:06.159 is where exams try to trap students. Oh, big 00:11:06.159 --> 00:11:08.419 time. Let's walk through this clinical progression 00:11:08.419 --> 00:11:10.440 because this is where the dominoes really start 00:11:10.440 --> 00:11:12.799 to fall. What happens when a patient hits roughly 00:11:12.799 --> 00:11:15.879 15 to 20 percent blood volume loss? This is the 00:11:15.879 --> 00:11:18.950 very beginning of the cascade. At 15 to 20 percent 00:11:18.950 --> 00:11:21.929 loss, the reserve tank is empty and the body 00:11:21.929 --> 00:11:24.090 starts to panic slightly. Okay, so what do we 00:11:24.090 --> 00:11:27.049 see? You are going to see tachycardia. The heart 00:11:27.049 --> 00:11:29.889 rate starts to climb. You will see tachypnea. 00:11:29.990 --> 00:11:32.549 The breeding rate speeds up to try and get more 00:11:32.549 --> 00:11:34.649 oxygen to the tissues. Makes sense. And you'll 00:11:34.649 --> 00:11:37.669 notice delayed capillary refill. If you press 00:11:37.669 --> 00:11:40.070 on her fingernail, the pink color takes a few 00:11:40.070 --> 00:11:43.549 extra seconds to return. And crucially, the text 00:11:43.549 --> 00:11:46.549 mentions a narrowed pulse pressure. I really 00:11:46.549 --> 00:11:48.610 want to highlight this because I know a lot of 00:11:48.610 --> 00:11:51.169 nurses and nursing students who look at a blood 00:11:51.169 --> 00:11:55.710 pressure monitor see 110 over 80 and feel completely 00:11:55.710 --> 00:11:58.029 relieved. Right. Are you saying that number is 00:11:58.029 --> 00:12:00.490 effectively lying to us? I am saying that number 00:12:00.490 --> 00:12:02.990 is painting a false picture of stability and 00:12:02.990 --> 00:12:05.669 it is the single biggest trap in obstetric nursing. 00:12:05.710 --> 00:12:08.769 Wow. Do not wait for the blood pressure to drop. 00:12:08.929 --> 00:12:11.330 Let's break down the physiology of why this happens. 00:12:11.389 --> 00:12:14.100 Please do. When a patient loses that first 15 00:12:14.100 --> 00:12:17.000 to 20 percent of their blood, the body's sympathetic 00:12:17.000 --> 00:12:20.360 nervous system kicks in. It releases catecholamines, 00:12:20.659 --> 00:12:23.639 like epinephrine, to clamp down on the peripheral 00:12:23.639 --> 00:12:26.799 blood vessels in the arms and legs. Vasoconstriction 00:12:26.799 --> 00:12:29.019 is trying to squeeze the remaining blood into 00:12:29.019 --> 00:12:30.840 the core to protect the brain and the heart. 00:12:31.100 --> 00:12:34.019 Exactly. Now, the top number of your blood pressure, 00:12:34.299 --> 00:12:36.980 the systolic pressure, measures the force of 00:12:36.980 --> 00:12:39.500 the heart pumping. Right. The bottom number, 00:12:39.580 --> 00:12:41.610 the diastolic pressure, measures the resting 00:12:41.610 --> 00:12:44.509 resistance in the blood vessels. When the body 00:12:44.509 --> 00:12:47.070 clamps down and vasoconstricts those peripheral 00:12:47.070 --> 00:12:49.850 vessels, it artificially elevates the diastolic 00:12:49.850 --> 00:12:52.990 pressure. Oh, so the bottom number goes up. Right. 00:12:53.309 --> 00:12:55.690 Meanwhile, the top number, the systolic, might 00:12:55.690 --> 00:12:58.070 stay the same or drop just a tiny bit because 00:12:58.070 --> 00:13:00.450 there is less overall volume to pump. I see. 00:13:00.789 --> 00:13:03.129 So your patient goes from a normal baseline of, 00:13:03.129 --> 00:13:07.669 say, 120 over 70 to a pressure of 115 over 95. 00:13:07.889 --> 00:13:10.149 The numbers get closer together. The gap narrows. 00:13:10.210 --> 00:13:12.750 Yes. That is the narrowed pulse pressure. So 00:13:12.750 --> 00:13:15.549 the heart rate is 110, the breathing is 24, and 00:13:15.549 --> 00:13:19.149 the blood pressure is 115 over 95. And if you 00:13:19.149 --> 00:13:21.629 only look at the top number of the blood pressure, 00:13:21.730 --> 00:13:24.350 you will think she is fine. But she is already 00:13:24.350 --> 00:13:27.149 compensating for significant blood loss. That 00:13:27.149 --> 00:13:29.690 is terrifying. Overt hypotension, where that 00:13:29.690 --> 00:13:32.409 top number finally crashes down to 80 or 70, 00:13:32.769 --> 00:13:35.590 does not occur until the patient has lost 30 00:13:35.590 --> 00:13:38.370 % or more of their blood volume. So by the time 00:13:38.370 --> 00:13:41.899 you see true hypotension, the compensatory mechanisms 00:13:41.899 --> 00:13:44.629 have completely failed. The body has given up. 00:13:44.830 --> 00:13:46.570 If you are waiting for a low blood pressure, 00:13:46.830 --> 00:13:49.429 you have entirely missed the window for early 00:13:49.429 --> 00:13:51.889 intervention. You are no longer preventing a 00:13:51.889 --> 00:13:54.909 crisis. You are managing a catastrophe. Precisely. 00:13:54.929 --> 00:13:57.629 And if we let that continue and they hit 40 to 00:13:57.629 --> 00:14:00.549 50 percent blood loss. Oh boy. At that point, 00:14:00.610 --> 00:14:02.889 you are seeing oliguria, which means the kidneys 00:14:02.889 --> 00:14:04.750 have entirely stopped producing urine because 00:14:04.750 --> 00:14:06.769 the body has completely shut off blood flow to 00:14:06.769 --> 00:14:09.470 them to save the brain. You are looking at profound, 00:14:09.750 --> 00:14:13.149 irreversible shock. coma, and ultimately death. 00:14:13.870 --> 00:14:16.409 This emphasizes why visual estimation of blood 00:14:16.409 --> 00:14:19.049 loss is so incredibly dangerous. Yes, it really 00:14:19.049 --> 00:14:22.090 does. The text clearly states that just looking 00:14:22.090 --> 00:14:24.950 at a peripad or a pool of blood on the bed and 00:14:24.950 --> 00:14:27.750 guessing, like, oh, that looks like 300 mL, is 00:14:27.750 --> 00:14:30.190 highly inaccurate and totally subjective. You 00:14:30.190 --> 00:14:32.590 have to use quantitative blood loss. Right, weighing 00:14:32.590 --> 00:14:35.090 the pads and the checks on a scale. One gram 00:14:35.090 --> 00:14:38.190 of weight equals one milliliter of blood. We 00:14:38.190 --> 00:14:41.320 rely on hard data, not guesses. Especially when 00:14:41.320 --> 00:14:43.299 the patient's vital signs might be trying to 00:14:43.299 --> 00:14:45.600 trick us with that narrowed pulse pressure. Okay, 00:14:45.639 --> 00:14:47.919 so let's put this into a clinical scenario. You 00:14:47.919 --> 00:14:50.679 are at the bedside. You weigh the pads and realize 00:14:50.679 --> 00:14:53.080 your patient has lost 900 milliliters of blood, 00:14:53.539 --> 00:14:56.159 her heart rate is creeping up to 115, and her 00:14:56.159 --> 00:14:59.220 pulse pressure is narrowing. Okay. What is your 00:14:59.220 --> 00:15:02.519 literal first physical move? What are the priority 00:15:02.519 --> 00:15:05.059 nursing actions? First, you do not leave the 00:15:05.059 --> 00:15:07.429 patient. You evaluate the bleeding immediately, 00:15:07.850 --> 00:15:10.409 and simultaneously, you mobilize resources. You 00:15:10.409 --> 00:15:12.370 call for help. Yes. Hit the emergency light, 00:15:12.549 --> 00:15:14.769 yell down the hall, activate the hemorrhage protocol. 00:15:15.429 --> 00:15:18.909 PPH is an unequivocal, multidisciplinary emergency. 00:15:19.129 --> 00:15:22.149 You cannot fix it alone. Right. Box 12 .2 in 00:15:22.149 --> 00:15:24.289 the text outlines the general management. It 00:15:24.289 --> 00:15:27.230 says monitor and maintain circulation. In practical 00:15:27.230 --> 00:15:30.519 terms, that means establishing IV access. But 00:15:30.519 --> 00:15:34.000 not just any IV. The gold standard is two large 00:15:34.000 --> 00:15:36.980 bore intravenous lines. Two large bore IV. We 00:15:36.980 --> 00:15:40.440 are talking 18 gauge or 16 gauge needles. Why? 00:15:40.620 --> 00:15:43.539 Because of fluid dynamics. If your patient has 00:15:43.539 --> 00:15:47.179 a tiny 22 gauge fiam in their hand, you physically 00:15:47.179 --> 00:15:50.299 cannot push thick red blood cells or liters of 00:15:50.299 --> 00:15:52.720 saline fast enough through that tiny straw to 00:15:52.720 --> 00:15:55.100 save her life. That makes sense. You need a massive 00:15:55.100 --> 00:15:57.360 pipeline. Think of a cocktail straw versus a 00:15:57.360 --> 00:15:59.379 garden hose. You need the hose. Exactly. You 00:15:59.379 --> 00:16:01.659 get those two large bore lines in, you draw blood 00:16:01.659 --> 00:16:04.320 immediately to type and cross match for a transfusion, 00:16:04.639 --> 00:16:06.679 you send off a coagulation profile to see if 00:16:06.679 --> 00:16:08.940 her blood is still capable of clotting, and you 00:16:08.940 --> 00:16:11.370 open up a rapid infusion of crystalloids like 00:16:11.370 --> 00:16:13.649 normal saline or lactated ringers. These are 00:16:13.649 --> 00:16:16.129 your foundational safety nets, because now that 00:16:16.129 --> 00:16:18.230 we have recognized the crisis and mobilized her 00:16:18.230 --> 00:16:20.789 team, we have to find out why she is bleeding 00:16:20.789 --> 00:16:23.049 and actually fix it. Which brings us to the most 00:16:23.049 --> 00:16:25.970 statistically probable cause. If I told you that 00:16:25.970 --> 00:16:28.490 80 % of all postpartum hemorrhages are caused 00:16:28.490 --> 00:16:31.149 by one single mechanism, wouldn't that be the 00:16:31.149 --> 00:16:33.529 absolute first thing you check? It absolutely 00:16:33.529 --> 00:16:36.330 has to be, and that mechanism is uterine atony. 00:16:37.180 --> 00:16:40.159 Let's really dig into the anatomy and physiology 00:16:40.159 --> 00:16:44.039 here. Atene literally means without tone. Right. 00:16:44.360 --> 00:16:46.779 The text states that ordinarily, promptly after 00:16:46.779 --> 00:16:49.360 the delivery of the placenta, the uterine corpus 00:16:49.360 --> 00:16:51.919 contracts down on itself. That is the muscular 00:16:51.919 --> 00:16:54.320 tourniquet we talked about earlier. Atene is 00:16:54.320 --> 00:16:57.080 the failure of that muscle to contract. And because 00:16:57.080 --> 00:16:59.620 it fails to contract, those spiral arteries are 00:16:59.620 --> 00:17:02.139 just left wide open, pumping maternal blood out 00:17:02.139 --> 00:17:04.519 into the uterus and out of the vagina. So how 00:17:04.519 --> 00:17:06.480 do we assess for this? What does it physically 00:17:06.480 --> 00:17:09.240 feel like when you palpate the patient's abdomen? 00:17:09.599 --> 00:17:11.559 When you place your hand flat on the patient's 00:17:11.559 --> 00:17:15.019 lower abdomen, an expected normal finding is 00:17:15.019 --> 00:17:18.140 a firm contracted uterine fundus. It should feel 00:17:18.140 --> 00:17:21.240 like a hard grapefruit or a dense softball resting 00:17:21.240 --> 00:17:23.680 right around the level of the umbilicus. That 00:17:23.680 --> 00:17:25.839 firmness tells you the muscle fibers are locked 00:17:25.839 --> 00:17:28.220 tight. But the concerning finding, the hallmark 00:17:28.220 --> 00:17:30.660 sign of atonia, is what we call a boggy uterus. 00:17:30.740 --> 00:17:33.920 Boggy. It feels soft, doughy, pliable. It feels 00:17:33.920 --> 00:17:36.180 like a slightly under -inflated balloon or a 00:17:36.180 --> 00:17:39.599 wet sponge. It completely lacks that rigid definition. 00:17:40.000 --> 00:17:42.299 Now, exams will try to throw a nuance at you 00:17:42.299 --> 00:17:44.740 here. Always. Sometimes you massage the fundus, 00:17:44.880 --> 00:17:47.420 and it briefly firms up under your hand. But 00:17:47.420 --> 00:17:50.099 the moment you stop massaging, it relaxes and 00:17:50.099 --> 00:17:52.380 gets boggy again. That is still uterine atony. 00:17:52.640 --> 00:17:55.259 A healthy uterus should maintain its tone without 00:17:55.259 --> 00:17:58.460 constant physical manipulation. So if I find 00:17:58.460 --> 00:18:01.619 a boggy uterus, what is my priority nursing action? 00:18:01.819 --> 00:18:04.279 Do I call the doctor first? Do I go run and grab 00:18:04.279 --> 00:18:09.380 medication? Palpate, a boggy uterus. Your very 00:18:09.380 --> 00:18:11.200 first action before you leave the room, before 00:18:11.200 --> 00:18:14.240 you drop a med, is immediate bimanual uterine 00:18:14.240 --> 00:18:17.839 massage. Figure 12 .1 in the source text illustrates 00:18:17.839 --> 00:18:20.779 this perfectly. You do not just gently rub the 00:18:20.779 --> 00:18:22.839 belly. Right. I think a lot of people picture 00:18:22.839 --> 00:18:26.400 massage as a gentle, soothing motion. This is 00:18:26.400 --> 00:18:28.779 an aggressive, manipulative intervention. It 00:18:28.779 --> 00:18:30.980 is uncomfortable for the patient, but it is life 00:18:30.980 --> 00:18:33.200 -saving. Very uncomfortable. One hand goes on 00:18:33.200 --> 00:18:35.500 the abdomen, firmly compressing the fundus downward. 00:18:36.109 --> 00:18:38.529 hand, gloved of course, is inserted into the 00:18:38.529 --> 00:18:40.269 vagina so that pressure can be placed against 00:18:40.269 --> 00:18:43.599 the anterior lower uterine segment. You are physically 00:18:43.599 --> 00:18:45.740 sandwiching the bleeding uterus between your 00:18:45.740 --> 00:18:48.559 two hands and compressing the open vessels. While 00:18:48.559 --> 00:18:51.920 simultaneously irritating the muscle fibers to 00:18:51.920 --> 00:18:54.559 stimulate a contraction. You are acting as the 00:18:54.559 --> 00:18:56.200 tourniquet from the outside while the muscle 00:18:56.200 --> 00:18:59.400 tries to wake up. Exactly. And the text emphasizes 00:18:59.400 --> 00:19:01.859 that this bimanual massage should be maintained 00:19:01.859 --> 00:19:04.339 while preparations for other treatments are underway. 00:19:04.619 --> 00:19:06.940 You don't just massage for 10 seconds and stop 00:19:06.940 --> 00:19:09.680 to watch. No. You compress. You yell for help. 00:19:09.869 --> 00:19:12.230 and you wait for someone to bring you the uterotonics. 00:19:12.750 --> 00:19:15.670 Uterotonics. Those are the medications that force 00:19:15.670 --> 00:19:18.730 the uterus to contract. And as an exam coach, 00:19:18.930 --> 00:19:21.849 I can tell you that this specific class of medications 00:19:21.849 --> 00:19:24.690 is one of the most highly tested areas in all 00:19:24.690 --> 00:19:26.829 of obstetrics. You have to know what to give. 00:19:27.269 --> 00:19:29.230 But more importantly, you have to know when a 00:19:29.230 --> 00:19:32.430 medication is absolutely contraindicated. This 00:19:32.430 --> 00:19:34.690 is what I call the medication contraindication 00:19:34.690 --> 00:19:37.579 trap. And getting this wrong in real life can 00:19:37.579 --> 00:19:39.779 literally kill a patient. So let's start with 00:19:39.779 --> 00:19:43.119 our absolute frontline gold standard uterotonic 00:19:43.119 --> 00:19:46.180 oxytocin. Oxytocin, commonly known as pedosin, 00:19:46.460 --> 00:19:49.339 is the first line defense. The standard protocol 00:19:49.339 --> 00:19:52.559 is usually 10 to 40 units mixed into one liter 00:19:52.559 --> 00:19:56.180 of normal saline or lactated ringers and infused 00:19:56.180 --> 00:19:59.599 rapidly through that large bore 4V. It works 00:19:59.599 --> 00:20:01.900 by binding two receptors on the uterine muscle 00:20:01.900 --> 00:20:04.380 cells, causing them to contract rhythmically, 00:20:04.579 --> 00:20:07.140 just like in labor. Yep. It's relatively safe 00:20:07.140 --> 00:20:10.180 and fast -acting. But if oxytocin isn't enough, 00:20:10.359 --> 00:20:13.160 we move down the algorithm. The next major player 00:20:13.160 --> 00:20:16.000 is methylurganavine, commonly known as methargine. 00:20:16.400 --> 00:20:18.700 Methargine is an incredibly potent medication 00:20:18.700 --> 00:20:21.720 that causes sustained titanic contractions within 00:20:21.720 --> 00:20:24.160 minutes. But the exams will test you on how to 00:20:24.160 --> 00:20:26.740 administer it safely. First, the text clearly 00:20:26.740 --> 00:20:29.680 states it is given intramuscularly, usually in 00:20:29.680 --> 00:20:31.920 the vastus lateralis of the thigh. Wait, if the 00:20:31.920 --> 00:20:33.779 patient is bleeding to death, why wouldn't I 00:20:33.779 --> 00:20:35.779 just push it directly into her vivine line to 00:20:35.779 --> 00:20:38.480 get it there faster? That is the trap. Never, 00:20:38.500 --> 00:20:41.799 ever give methadone as a rapid vivine. Administering 00:20:41.799 --> 00:20:44.599 it rapidly into a vein can cause a sudden catastrophic 00:20:44.599 --> 00:20:46.839 spike in blood pressure. Oh wow. Which brings 00:20:46.839 --> 00:20:49.279 us to the absolute contraindication. You never 00:20:49.279 --> 00:20:51.440 give methadone to a patient with hypertensive 00:20:51.440 --> 00:20:54.220 disorders. So if my patient came in with preeclampsia 00:20:54.220 --> 00:20:58.259 or gestational hypertension or even just a baseline 00:20:58.259 --> 00:21:01.549 history of high blood pressure. Methargyne is 00:21:01.549 --> 00:21:03.869 entirely off the table. Exactly. If I give her 00:21:03.869 --> 00:21:05.809 methargyne, I might stop the bleeding, but I 00:21:05.809 --> 00:21:08.069 could cause a massive stroke right there in the 00:21:08.069 --> 00:21:11.049 bed. That is wild. You always check the patient's 00:21:11.049 --> 00:21:12.869 blood pressure baseline before administering 00:21:12.869 --> 00:21:15.910 methargyne. Always. So if your patient has preeclampsia, 00:21:15.990 --> 00:21:18.029 what do you use instead? You move to the next 00:21:18.029 --> 00:21:21.750 medication. 15 -methyl -PGF2A, which goes by 00:21:21.750 --> 00:21:25.309 the brand name Hemibate. Hemibate is a synthetic 00:21:25.309 --> 00:21:28.170 prostaglandin. And just like methargyne, it has 00:21:28.170 --> 00:21:31.339 a massive red flag contra - indication that instructors 00:21:31.339 --> 00:21:34.019 just love to test. The text states hemibate should 00:21:34.019 --> 00:21:36.880 be avoided or used with extreme caution in those 00:21:36.880 --> 00:21:39.960 with cardiac pulmonary liver or renal diseases. 00:21:40.279 --> 00:21:42.559 Pulmonary is the big one here. If you see a test 00:21:42.559 --> 00:21:44.859 question where a patient is hemorrhaging but 00:21:44.859 --> 00:21:47.640 her history includes asthma, hemibate is the 00:21:47.640 --> 00:21:50.220 wrong answer. Do you know why? Well, because 00:21:50.220 --> 00:21:53.349 prostaglandins affect smooth muscle. The uterus 00:21:53.349 --> 00:21:55.329 is a smooth muscle, so it makes it contract. 00:21:55.890 --> 00:21:58.750 But the bronchioles in the lungs are also surrounded 00:21:58.750 --> 00:22:02.150 by a smooth muscle. If you give hemabate to an 00:22:02.150 --> 00:22:05.509 asthmatic, it can trigger a severe, life -threatening 00:22:05.509 --> 00:22:07.930 bronchospasm. She literally won't be able to 00:22:07.930 --> 00:22:11.069 breathe. So to recap, methadiene is contraindicated 00:22:11.069 --> 00:22:14.069 in hypertension. Hemabate is contraindicated 00:22:14.069 --> 00:22:16.829 in asthma. These are absolute non -negotiables. 00:22:17.150 --> 00:22:19.410 for your exams and your practice. Now, there 00:22:19.410 --> 00:22:21.269 is another conceptual trap in this section that 00:22:21.269 --> 00:22:23.369 I found really fascinating. Let's call it the 00:22:23.369 --> 00:22:26.650 coagulation trap. Oh, I love this one. As humans, 00:22:26.950 --> 00:22:29.509 when we see profuse bleeding, our instinct is 00:22:29.509 --> 00:22:31.910 to think, oh, the blood isn't clotting properly. 00:22:32.109 --> 00:22:34.109 Right. We immediately assume there's a problem 00:22:34.109 --> 00:22:37.849 with platelets or fibrinogen, but the text explicitly 00:22:37.849 --> 00:22:40.829 clarifies this. It states that it is the muscular 00:22:40.829 --> 00:22:43.809 contraction of the uterus rather than blood coagulation 00:22:43.809 --> 00:22:46.470 that prevents excessive bleeding from the placental 00:22:46.470 --> 00:22:48.490 imbalances. plantation site. So atony bleeding 00:22:48.490 --> 00:22:51.009 is like trying to turn off a fire hose by stepping 00:22:51.009 --> 00:22:53.329 on it but the muscle is just too weak to press 00:22:53.329 --> 00:22:55.589 down on the hose. It does not matter how thick 00:22:55.589 --> 00:22:57.750 the water is or how well the blood can clot. 00:22:58.150 --> 00:23:00.869 If the hose is wide open the blood is going to 00:23:00.869 --> 00:23:03.740 pour out. Exactly. Antony happens regardless 00:23:03.740 --> 00:23:06.319 of normal clotting factors. You could have perfect 00:23:06.319 --> 00:23:08.119 lab results, but if that muscle doesn't clamp 00:23:08.119 --> 00:23:11.380 down, she will bleed out. That's why our primary 00:23:11.380 --> 00:23:13.619 intervention is physical massage and neutrotonics, 00:23:13.680 --> 00:23:15.539 not just pumping her full of platelets. Okay. 00:23:15.619 --> 00:23:17.859 We spent a lot of time on Antony because it's 00:23:17.859 --> 00:23:20.700 80 % of the problem. But I want to pose a scenario 00:23:20.700 --> 00:23:24.500 to you to transition us to the other 20%. Fit 00:23:24.500 --> 00:23:27.380 me. Let's say you walk into room four. You have 00:23:27.380 --> 00:23:29.859 a 32 -year -old patient who delivered an hour 00:23:29.859 --> 00:23:32.940 ago. She is bleeding heavily. You do exactly 00:23:32.940 --> 00:23:35.420 what we just discussed. You push your hand into 00:23:35.420 --> 00:23:38.279 her lower abdomen. You find the fundus. And the 00:23:38.279 --> 00:23:41.839 uterus is rock hard. OK. It is perfectly firm, 00:23:42.200 --> 00:23:44.319 midline, shaped exactly like that dense grapefruit 00:23:44.319 --> 00:23:47.039 we talked about. But bright red blood is still 00:23:47.039 --> 00:23:48.900 steadily flowing out of her. What did I miss? 00:23:49.160 --> 00:23:50.619 You didn't miss anything in your assessment. 00:23:50.759 --> 00:23:52.559 But that assessment tells you exactly what is 00:23:52.559 --> 00:23:55.569 happening. If the uterus is firm, Tone is not 00:23:55.569 --> 00:23:57.890 the issue. The tourniquet is working. You are 00:23:57.890 --> 00:24:00.769 now looking at physical barriers and trauma. 00:24:01.109 --> 00:24:03.589 Let's start with the physical barriers. Retained 00:24:03.589 --> 00:24:06.529 placenta. Let's define some jargon from the text 00:24:06.529 --> 00:24:08.450 so we understand exactly what's happening. Yeah, 00:24:08.470 --> 00:24:12.009 the text mentions that normally separation occurs 00:24:12.009 --> 00:24:14.910 because of cleavage between the zona basalis 00:24:14.910 --> 00:24:17.569 and the zona spongiosa. What does that actually 00:24:17.569 --> 00:24:19.609 mean in plain English? Well, the placenta is 00:24:19.609 --> 00:24:22.130 the organ that attaches to the uterine wall to 00:24:22.130 --> 00:24:25.109 feed the baby. Think of the zona spongiosa as 00:24:25.109 --> 00:24:28.049 the spongy, superficial layer of the uterine 00:24:28.049 --> 00:24:30.910 lining. OK. And the zona basalis as the deep 00:24:30.910 --> 00:24:33.829 foundational layer. Normally, after the baby 00:24:33.829 --> 00:24:36.589 is born, the placenta cleanly shears off right 00:24:36.589 --> 00:24:38.849 between those two layers, like peeling off a 00:24:38.849 --> 00:24:41.130 piece of Velcro. But sometimes it doesn't peel 00:24:41.130 --> 00:24:44.009 off cleanly. A piece of the placenta, or even 00:24:44.009 --> 00:24:46.769 just a small fragment, gets left behind inside 00:24:46.769 --> 00:24:49.289 the uterus. And this acts like a physical wedge. 00:24:49.880 --> 00:24:52.259 Exactly. The uterus is trying to contract, but 00:24:52.259 --> 00:24:54.559 there is a chunk of tissue inside the cavity, 00:24:54.740 --> 00:24:56.759 preventing it from clamping all the way down. 00:24:57.019 --> 00:24:59.059 The vessels underneath that retained fragment 00:24:59.059 --> 00:25:01.980 continue to bleed profusely. The text mentions 00:25:01.980 --> 00:25:04.319 checking the placenta for missing cotyledons. 00:25:04.720 --> 00:25:07.779 A cotyledon is basically just a lobe or a segment 00:25:07.779 --> 00:25:10.339 of the maternal side of the placenta, right? 00:25:10.420 --> 00:25:13.539 It looks kind of like a dark red meaty cobblestone. 00:25:13.759 --> 00:25:16.579 Yes. This is why a key nursing priority, which 00:25:16.579 --> 00:25:18.880 actually happens before the hemorrhage, is inspection. 00:25:19.000 --> 00:25:21.619 Right. After expulsion, every single placenta 00:25:21.619 --> 00:25:23.819 must be laid out and thoroughly inspected by 00:25:23.819 --> 00:25:26.039 the provider and the nurse. You are looking to 00:25:26.039 --> 00:25:28.160 see if it is perfectly intact or if it looks 00:25:28.160 --> 00:25:31.380 like a piece was ripped away. Even a tiny retained 00:25:31.380 --> 00:25:34.480 fragment can cause devastating intractable bleeding. 00:25:34.980 --> 00:25:37.480 Closely related to this, but honestly far more 00:25:37.480 --> 00:25:40.160 dangerous, is the placenta accretus spectrum. 00:25:40.400 --> 00:25:43.549 Yes. This is an abnormal adherence of the placenta 00:25:43.549 --> 00:25:45.829 to the uterine wall. It doesn't just fail to 00:25:45.829 --> 00:25:48.869 peel off cleanly, it is morbidly glued to the 00:25:48.869 --> 00:25:51.170 muscle. The terminology here is highly testable 00:25:51.170 --> 00:25:53.150 because there are three degrees of severity. 00:25:53.930 --> 00:25:55.470 I want you to look at the suffix of each word. 00:25:55.670 --> 00:25:57.829 Okay, break it down. Placenta accreta simply 00:25:57.829 --> 00:26:00.410 means it is abnormally attached to the superficial 00:26:00.410 --> 00:26:03.329 lining. Placenta accreta means the placenta literally 00:26:03.329 --> 00:26:06.319 invades into the myometrium. the uterine muscle 00:26:06.319 --> 00:26:09.200 itself. And placenta procreta means the placental 00:26:09.200 --> 00:26:11.799 tissue penetrates entirely through the thickness 00:26:11.799 --> 00:26:14.480 of the uterine muscle. Sometimes invading surrounding 00:26:14.480 --> 00:26:17.480 organs like the bladder or bowels. Exactly. So 00:26:17.480 --> 00:26:20.980 accreta is attached, increta invades, procreta 00:26:20.980 --> 00:26:24.140 penetrates. That makes it so much easier to remember. 00:26:24.559 --> 00:26:26.940 And why does this happen? The text points out 00:26:26.940 --> 00:26:30.880 a massive flashing red light correlation with 00:26:30.880 --> 00:26:33.829 previous cesarean sections. Yes. When a patient 00:26:33.829 --> 00:26:36.349 has a C -section, the surgeon cuts through the 00:26:36.349 --> 00:26:38.529 uterine muscle and it heals with the scar. Makes 00:26:38.529 --> 00:26:41.650 sense. Scar tissue lacks the normal healthy endometrial 00:26:41.650 --> 00:26:44.670 lining. If a future placenta implants over that 00:26:44.670 --> 00:26:47.230 scar, especially if the patient has placenta 00:26:47.230 --> 00:26:49.529 previa, where the placenta covers the cervix, 00:26:50.009 --> 00:26:52.250 the placental roots dig deep into the muscle 00:26:52.250 --> 00:26:54.289 looking for a blood supply because the normal 00:26:54.289 --> 00:26:56.789 spongy layer just isn't there. The statistics 00:26:56.789 --> 00:26:59.509 are staggering. If a patient has placenta previa, 00:26:59.950 --> 00:27:03.329 the rate of morbidly adherent placenta with every 00:27:03.329 --> 00:27:05.789 c -section. With her first c -section, it's a 00:27:05.789 --> 00:27:09.390 3 % risk. By her fourth, it's a 60 % risk. And 00:27:09.390 --> 00:27:11.789 with six or more previous cesareans, the risk 00:27:11.789 --> 00:27:15.130 is greater than 67%. It fundamentally alters 00:27:15.130 --> 00:27:18.450 the birth plan. If a placenta is deeply invaded 00:27:18.450 --> 00:27:20.589 into the muscle and you try to pull it out, you 00:27:20.589 --> 00:27:23.089 will literally rip the uterus apart. The bleeding 00:27:23.089 --> 00:27:26.049 is catastrophic. Often these patients require 00:27:26.049 --> 00:27:28.529 a planned immediate hysterectomy at the time 00:27:28.529 --> 00:27:31.480 of their c -section just to survive. Okay, so 00:27:31.480 --> 00:27:33.200 that's the barrier side of things. Let's look 00:27:33.200 --> 00:27:36.000 at the trauma side of your scenario. The uterus 00:27:36.000 --> 00:27:38.759 is firm, but she's bleeding bright red blood. 00:27:39.099 --> 00:27:42.779 This is highly indicative of genital tract lacerations. 00:27:43.000 --> 00:27:45.619 Lacerations are tears in the tissue of the cervix, 00:27:45.779 --> 00:27:48.940 the vagina, or the perineum. They are less common 00:27:48.940 --> 00:27:51.299 than atinae, but they can bleed just as aggressively. 00:27:51.519 --> 00:27:53.579 They typically happen during instrumented deliveries. 00:27:53.660 --> 00:27:56.220 Right. Like when a provider uses forceps or a 00:27:56.220 --> 00:27:58.500 vacuum extractor. Or during manipulative deliveries, 00:27:58.779 --> 00:28:01.099 like pulling out a breech baby. They also happen 00:28:01.099 --> 00:28:03.559 in precipitous labor, right? If the baby comes 00:28:03.559 --> 00:28:06.190 flying out in two hours, The cervical and vaginal 00:28:06.190 --> 00:28:08.170 tissues simply haven't had the time to slowly 00:28:08.170 --> 00:28:11.430 stretch and accommodate the head, so they tear. 00:28:11.849 --> 00:28:14.250 Exactly. And the nursing trap here is that you 00:28:14.250 --> 00:28:17.049 must differentiate between adeny and a laceration 00:28:17.049 --> 00:28:19.900 immediately. Because if you have a patient bleeding 00:28:19.900 --> 00:28:22.940 from a ripped cervix and you just stand there 00:28:22.940 --> 00:28:25.180 aggressively massaging an already rock -hard 00:28:25.180 --> 00:28:28.400 uterus, you are performing a fatal nursing error. 00:28:28.599 --> 00:28:30.640 You are wasting time treating the wrong problem. 00:28:31.039 --> 00:28:33.019 You have to ensure the provider has adequate 00:28:33.019 --> 00:28:35.940 lighting, proper instruments and assistance to 00:28:35.940 --> 00:28:38.640 visually locate that tear and surgically repair 00:28:38.640 --> 00:28:41.539 it with sutures. You can't massage away a laceration. 00:28:41.779 --> 00:28:44.259 So true. Now, what about trauma we can't see? 00:28:44.279 --> 00:28:47.059 Let's talk about hematomas. Hematomas are incredibly 00:28:47.059 --> 00:28:49.640 sneaky. And they are a massive exam favorite. 00:28:49.960 --> 00:28:52.819 A hematoma is concealed bleeding. A blood vessel 00:28:52.819 --> 00:28:55.480 ruptures underneath the intact skin or mucosa 00:28:55.480 --> 00:28:57.980 of the vulva, the vagina, or the pelvis. Right. 00:28:58.099 --> 00:29:00.539 The blood pools and expands in the sub -eucosal 00:29:00.539 --> 00:29:02.819 tissues, but it doesn't break through the surface. 00:29:03.059 --> 00:29:05.920 So the pad looks completely clean. There is no 00:29:05.920 --> 00:29:09.099 visible vaginal bleeding. How on earth is a nurse 00:29:09.099 --> 00:29:11.140 supposed to recognize that a patient is hemorrhaging 00:29:11.140 --> 00:29:14.200 internally into her perineum? The defining characteristic 00:29:14.200 --> 00:29:18.049 is pain. exquisite, unrelenting, severe pain. 00:29:18.269 --> 00:29:20.609 But wait, every woman who just pushed a baby 00:29:20.609 --> 00:29:22.829 out is going to be in pain down there. Yeah. 00:29:22.950 --> 00:29:26.690 How do I differentiate normal postpartum soreness 00:29:26.690 --> 00:29:29.690 from a hematoma? It is the type and severity 00:29:29.690 --> 00:29:33.250 of the pain. Expected pain is soreness, an aching 00:29:33.250 --> 00:29:36.109 discomfort that improves with ice and ibuprofen. 00:29:36.349 --> 00:29:39.289 Okay. The pain of a hematoma is disproportionate 00:29:39.289 --> 00:29:42.210 to the delivery. It is a feeling of intense, 00:29:42.210 --> 00:29:45.359 severe pressure. Patients often say, it feels 00:29:45.359 --> 00:29:47.900 like I have to push another baby out or it feels 00:29:47.900 --> 00:29:50.119 like my bottom is going to explode. Oh, wow. 00:29:50.240 --> 00:29:52.099 And if you look at the vulva, you might see a 00:29:52.099 --> 00:29:55.079 rapidly enlarging, tense, purplish mass. The 00:29:55.079 --> 00:29:57.859 pain versus bleeding trap. Students expect hemorrhage 00:29:57.859 --> 00:30:00.599 to always involve visible blood. But if a postpartum 00:30:00.599 --> 00:30:02.960 patient is complaining of agonizing caroneal 00:30:02.960 --> 00:30:04.960 pressure and her heart rate is climbing, you 00:30:04.960 --> 00:30:07.180 must suspect a hidden hemorrhage, a hematoma. 00:30:07.420 --> 00:30:09.960 For nursing management, the text provides very 00:30:09.960 --> 00:30:12.380 clear guidelines based on size. If the hematoma 00:30:12.380 --> 00:30:14.440 is less than five centimeters and is not actively 00:30:14.440 --> 00:30:16.680 enlarging, it is usually managed expectantly. 00:30:17.119 --> 00:30:18.980 You draw a line around the border with a pen 00:30:18.980 --> 00:30:21.960 to monitor its size. You check vital signs frequently. 00:30:22.559 --> 00:30:24.980 You monitor her urinary output to ensure the 00:30:24.980 --> 00:30:27.339 swelling isn't blocking her urethra. And you 00:30:27.339 --> 00:30:30.759 apply ice packs. But if it is larger than 5 cm, 00:30:30.980 --> 00:30:33.240 or if that line you drew is suddenly expanding 00:30:33.240 --> 00:30:35.819 rapidly, that requires surgical management. The 00:30:35.819 --> 00:30:38.680 provider has to take her to the OR, slice it 00:30:38.680 --> 00:30:41.779 open, drain the blood, and leg it or tie off 00:30:41.779 --> 00:30:43.880 the bleeding vessels. Before we leave section 00:30:43.880 --> 00:30:46.539 3, I want to highlight one fascinating clinical 00:30:46.539 --> 00:30:48.579 trap the text mentions regarding the treatment 00:30:48.579 --> 00:30:51.920 for retained placenta. If tissue is retained, 00:30:52.079 --> 00:30:54.380 a provider might use an instrument called a curette 00:30:54.380 --> 00:30:56.559 to scrape the lining of the uterus and remove 00:30:56.559 --> 00:31:00.720 the fragment. or dilation and curatage. But the 00:31:00.720 --> 00:31:03.500 text specifically warns that overly vigorous 00:31:03.500 --> 00:31:06.759 curatage can lead to a complication called Asherman's 00:31:06.759 --> 00:31:09.480 syndrome. What is that? Asherman's syndrome occurs 00:31:09.480 --> 00:31:11.519 when the scraping is too aggressive and damages 00:31:11.519 --> 00:31:13.599 the foundational layer, the zone of basalis. 00:31:13.940 --> 00:31:16.779 The uterus heals by forming severe intruder and 00:31:16.779 --> 00:31:20.000 adhesions basically, thick scar tissue that glues 00:31:20.000 --> 00:31:22.079 the front and back walls of the uterus together. 00:31:22.259 --> 00:31:24.119 Which means the patient loses her functional 00:31:24.119 --> 00:31:27.200 endometrial lining. Yes. This can lead to amenorrhea. 00:31:27.299 --> 00:31:29.539 She stops having a period. It causes profound 00:31:29.539 --> 00:31:31.799 infertility. And if she does manage to get pregnant, 00:31:32.319 --> 00:31:34.180 it drastically increases her risk for future 00:31:34.180 --> 00:31:37.480 miscarriages or, ironically, placenta accreta. 00:31:37.690 --> 00:31:41.529 Wow. It is a stark reminder that every medical 00:31:41.529 --> 00:31:45.329 intervention, even life -saving ones, carry significant 00:31:45.329 --> 00:31:47.849 long -term risks for the patient. Okay. We are 00:31:47.849 --> 00:31:50.569 moving into our final major clinical area. We 00:31:50.569 --> 00:31:52.890 have covered the pump, which is the uterine muscle, 00:31:52.910 --> 00:31:55.210 and we've covered the pipes, which are the lacerations 00:31:55.210 --> 00:31:57.490 and the hematomas. But what happens when the 00:31:57.490 --> 00:32:00.150 blood itself loses the physical ability to clot? 00:32:00.490 --> 00:32:03.680 Or when the entire... structural integrity of 00:32:03.680 --> 00:32:06.480 the uterus just completely fails. We are entering 00:32:06.480 --> 00:32:08.880 the realm of catastrophic systemic failures. 00:32:09.180 --> 00:32:12.240 These are rare compared to atony, but their lethality 00:32:12.240 --> 00:32:15.259 is just off the charts. Rapid nursing recognition 00:32:15.259 --> 00:32:17.579 here is often the patient's only chance of survival 00:32:17.579 --> 00:32:21.240 because these conditions require a massive, highly 00:32:21.240 --> 00:32:23.700 coordinated, multidisciplinary resuscitation. 00:32:24.279 --> 00:32:27.000 Let's start with coagulation defects, specifically 00:32:27.000 --> 00:32:30.579 disseminated intravascular coagulation or DIC. 00:32:30.829 --> 00:32:34.170 The text lists conditions that trigger DIC, like 00:32:34.170 --> 00:32:36.710 abruptio placenta, where the placenta tears away 00:32:36.710 --> 00:32:40.230 prematurely, sepsis, preeclampsia, or acute fatty 00:32:40.230 --> 00:32:42.509 liver of pregnancy. But the most crucial sentence 00:32:42.509 --> 00:32:44.650 in that section, the one that every nurse must 00:32:44.650 --> 00:32:47.940 internalize, is this. It also should be recalled 00:32:47.940 --> 00:32:51.220 that perfuse hemorrhage itself can lead to coagulopathy, 00:32:51.359 --> 00:32:53.660 thus creating a vicious cycle of bleeding. I 00:32:53.660 --> 00:32:55.519 really want to break this down because the concept 00:32:55.519 --> 00:32:57.799 of bleeding causes bleeding sounds like a total 00:32:57.799 --> 00:33:00.460 paradox. How does losing blood make you lose 00:33:00.460 --> 00:33:02.940 the ability to clot? Think of your clotting factors, 00:33:03.140 --> 00:33:05.359 your platelets, your fibrinogen, your coagulation 00:33:05.359 --> 00:33:07.700 proteins as a finite army inside your blood. 00:33:07.740 --> 00:33:10.359 Okay, I can picture that. When you have a massive 00:33:10.359 --> 00:33:12.859 adeny hemorrhage, that army rushes to the site 00:33:12.859 --> 00:33:15.880 to try and plug the holes. But the flow is so 00:33:15.720 --> 00:33:19.000 fast that millions of these soldiers are literally 00:33:19.000 --> 00:33:21.099 washed out of the body onto the floor. And are 00:33:21.099 --> 00:33:23.660 consumed. They're consumed faster than the liver 00:33:23.660 --> 00:33:26.819 can manufacture new ones. At the same time, because 00:33:26.819 --> 00:33:28.839 the patient is going into shock and their tissues 00:33:28.839 --> 00:33:32.640 are starved of oxygen, The body panics and starts 00:33:32.640 --> 00:33:35.680 forming millions of microscopic clots in the 00:33:35.680 --> 00:33:37.799 small blood vessels everywhere else in the body. 00:33:37.880 --> 00:33:40.420 Oh, completely depleting whatever clotting factors 00:33:40.420 --> 00:33:43.720 remain. Exactly. So now the patient has no platelets 00:33:43.720 --> 00:33:46.440 or fibrinogen left. Her blood becomes as thin 00:33:46.440 --> 00:33:49.200 as water. She starts bleeding not just from the 00:33:49.200 --> 00:33:52.480 uterus, but from her IV sites, from her gums, 00:33:52.839 --> 00:33:55.720 from her Foley catheter. That is DIC. And that 00:33:55.720 --> 00:33:58.269 leads us to the bleeding cycle trap. When a patient 00:33:58.269 --> 00:34:01.369 is hemorrhaging a novice nurse might think I 00:34:01.369 --> 00:34:03.410 just need to keep her blood pressure up I'll 00:34:03.410 --> 00:34:05.690 pump her full of liters of normal saline and 00:34:05.690 --> 00:34:07.549 maybe I'll give her some packed red blood cells 00:34:07.549 --> 00:34:10.090 But if you just give saline and red blood cells 00:34:10.090 --> 00:34:12.789 you are actually making the DIC worse, right? 00:34:13.090 --> 00:34:15.329 Exactly saline doesn't have clotting factors 00:34:15.579 --> 00:34:18.000 Cacked red blood cells don't have clotting factors. 00:34:18.159 --> 00:34:20.340 So if you pump liters of these fluids into a 00:34:20.340 --> 00:34:22.760 bleeding patient, you are artificially raising 00:34:22.760 --> 00:34:25.239 her blood pressure, which pushes more blood out. 00:34:25.460 --> 00:34:28.199 While simultaneously diluting the few remaining 00:34:28.199 --> 00:34:30.400 clotting factors she has left in her bloodstream, 00:34:31.019 --> 00:34:33.039 you are thinning her blood even further. Which 00:34:33.039 --> 00:34:35.440 means we have to talk about modern blood component 00:34:35.440 --> 00:34:39.519 therapy. Table 12 .1 in the text mentions a crucial 00:34:39.519 --> 00:34:42.159 shift in philosophy regarding transfusions and 00:34:42.159 --> 00:34:45.079 massive hemorrhage. Right. For decades, the philosophy 00:34:45.079 --> 00:34:48.400 was reactive. You wait for lab results to prove 00:34:48.400 --> 00:34:50.639 the patient has low platelets or low fibrinogen, 00:34:50.860 --> 00:34:53.019 and then you order the specific clotting factors. 00:34:53.300 --> 00:34:55.199 But labs take an hour to come back. By then, 00:34:55.260 --> 00:34:57.960 the patient is dead. The modern high -yield recommendation 00:34:57.960 --> 00:35:00.880 is proactive intervention to prevent coagulopathy. 00:35:01.039 --> 00:35:03.659 The text defines severe ongoing hemorrhage as 00:35:03.659 --> 00:35:06.599 needing four or more units of packed RBCs over 00:35:06.599 --> 00:35:10.079 one hour or 10 or more units over 12 to 24 hours. 00:35:10.280 --> 00:35:12.400 When a patient hits that threshold, the standard 00:35:12.400 --> 00:35:16.099 of care shifts to a 1 .1 .1 transfusion ratio. 00:35:16.599 --> 00:35:19.699 One to one to one. This is essential exam knowledge. 00:35:20.119 --> 00:35:22.800 It means for every one unit of packed red blood 00:35:22.800 --> 00:35:25.559 cells you hang, you must also administer one 00:35:25.559 --> 00:35:29.079 unit of fresh frozen plasma and one unit of random 00:35:29.280 --> 00:35:31.960 donor platelets. I like to use an analogy here 00:35:31.960 --> 00:35:34.380 to visualize this. Go for it. Imagine a bridge 00:35:34.380 --> 00:35:36.619 is collapsed and you need to repair it quickly. 00:35:37.039 --> 00:35:40.019 Giving a patient just pack red blood cells is 00:35:40.019 --> 00:35:42.079 like sending a fleet of delivery trucks full 00:35:42.079 --> 00:35:44.199 of oxygen to the site. That's great, they brought 00:35:44.199 --> 00:35:46.980 the supplies. But if there's no road, the trucks 00:35:46.980 --> 00:35:49.420 just fall into the river. You need the fresh 00:35:49.420 --> 00:35:52.059 frozen plasma, the FFP, to bring the concrete 00:35:52.059 --> 00:35:54.280 and the raw materials, the fibrinogen. And you 00:35:54.280 --> 00:35:56.280 need the platelets to act as the construction 00:35:56.280 --> 00:35:58.340 workers to actually mix the concrete and fix 00:35:58.340 --> 00:36:00.760 the hole. That is a perfect analogy. You cannot 00:36:00.760 --> 00:36:03.360 fix the bridge with just trucks. You need the 00:36:03.360 --> 00:36:06.179 workers, the concrete, and the trucks simultaneously. 00:36:06.480 --> 00:36:10.019 That is the 1 .1 .1 ratio. Next on the list of 00:36:10.019 --> 00:36:13.460 catastrophes is amniotic fluid embolism, or AFE. 00:36:13.679 --> 00:36:16.400 The text describes this as a rare, sudden, and 00:36:16.400 --> 00:36:19.099 sometimes fatal obstetric complication thought 00:36:19.099 --> 00:36:21.719 to be caused by the entry of amniotic fluid into 00:36:21.719 --> 00:36:24.119 the maternal circulation. This usually happens 00:36:24.119 --> 00:36:27.059 during a difficult labor or immediately postpartum. 00:36:27.460 --> 00:36:30.679 The amniotic sac ruptures and through a tear 00:36:30.679 --> 00:36:33.579 in the uterine veins, a tiny amount of amniotic 00:36:33.579 --> 00:36:36.780 fluid, fetal cells, or hair enters the mother's 00:36:36.780 --> 00:36:39.559 bloodstream and travels to her lungs. Now early 00:36:39.559 --> 00:36:41.719 on scientists thought this was just a physical 00:36:41.719 --> 00:36:44.699 blockage like a regular pulmonary embolism. The 00:36:44.699 --> 00:36:47.090 debris clogs the lungs so she can't breathe. 00:36:47.590 --> 00:36:49.489 But it's much more sinister than that, isn't 00:36:49.489 --> 00:36:51.690 it? Yes, the physical blockage is really minor. 00:36:52.090 --> 00:36:54.230 The real danger is that the fetal cells trigger 00:36:54.230 --> 00:36:57.329 a massive, overwhelming anaphylactoid reaction. 00:36:57.469 --> 00:37:00.309 It is a biochemical cascade. The mother's immune 00:37:00.309 --> 00:37:03.670 system recognizes this foreign fluid and essentially 00:37:03.670 --> 00:37:05.889 self -destructs. The blood vessels in the lungs 00:37:05.889 --> 00:37:08.829 go into severe vasospasm, leading to immediate 00:37:08.829 --> 00:37:11.869 heart failure. The text outlines five abrupt 00:37:11.869 --> 00:37:14.809 sequential findings for AFE. And I mean abrupt, 00:37:14.809 --> 00:37:16.889 she can be talking to you one second and coding 00:37:16.889 --> 00:37:19.989 the next. Number one, sudden respiratory distress. 00:37:20.130 --> 00:37:23.190 She starts gasping for air. Number two, cyanosis. 00:37:23.190 --> 00:37:25.130 She turns blue because her lungs have clamped 00:37:25.130 --> 00:37:27.710 shut. Number three, cardiovascular collapse. 00:37:27.929 --> 00:37:31.570 Her heart fails. Number four, massive hemorrhage 00:37:31.570 --> 00:37:34.710 because the biochemical cascade instantly triggers 00:37:34.710 --> 00:37:38.650 DIC. And number five, coma. It is a total system 00:37:38.650 --> 00:37:41.590 crash. If you see a patient suddenly grasp her 00:37:41.590 --> 00:37:44.349 chest, turn blue, and lose consciousness, you 00:37:44.349 --> 00:37:47.570 hit the code button, you start CPR, and you prepare 00:37:47.570 --> 00:37:51.130 for immediate, massive, multi -system resuscitation. 00:37:51.309 --> 00:37:53.690 OK, let's pivot from the systemic crashes to 00:37:53.690 --> 00:37:56.710 the structural catastrophes. Uterine inversion. 00:37:57.030 --> 00:37:58.510 This sounds like something out of a horror movie. 00:37:58.730 --> 00:38:00.469 It is exactly what it sounds like. The uterus 00:38:00.469 --> 00:38:03.050 literally turns inside out. The top of the fundus 00:38:03.050 --> 00:38:05.949 collapses inward. extends down through the cervix 00:38:05.949 --> 00:38:08.409 and sometimes even protrudes past the vaginal 00:38:08.409 --> 00:38:11.190 opening. Figure 12 .3 in the text shows this 00:38:11.190 --> 00:38:14.010 visually and it is horrifying. It causes immediate 00:38:14.010 --> 00:38:16.730 profound neurogenic shock and severe hemorrhage. 00:38:16.849 --> 00:38:18.789 It often happens because a provider pulled too 00:38:18.789 --> 00:38:20.670 hard on the umbilical cord before the placenta 00:38:20.670 --> 00:38:23.429 fully detached, effectively pulling the inside 00:38:23.429 --> 00:38:25.909 of the uterus out. So what is the priority nursing 00:38:25.909 --> 00:38:27.929 action? The primary medical treatment is for 00:38:27.929 --> 00:38:30.269 the provider to take their hand, push the fundus 00:38:30.269 --> 00:38:32.769 back up through the vagina, and manually pop 00:38:32.769 --> 00:38:35.570 the uterus back into its correct anatomical position. 00:38:35.750 --> 00:38:38.349 But here is the critical nursing trap and I guarantee 00:38:38.349 --> 00:38:41.530 you will see this on an exam. the inversion medication 00:38:41.530 --> 00:38:44.289 trap. If you walk into a room and a patient is 00:38:44.289 --> 00:38:47.730 hemorrhaging, your reflex as a nurse is to immediately 00:38:47.730 --> 00:38:50.730 yell for oxytocin to clamp the uterus down. Do 00:38:50.730 --> 00:38:53.070 not do that. Think about the physics. If the 00:38:53.070 --> 00:38:55.010 uterus is inside out, hanging in the vagina, 00:38:55.369 --> 00:38:58.090 and you give oxytocin, the muscle is going to 00:38:58.090 --> 00:39:01.110 contract and turn into a rock -hard fist -size 00:39:01.110 --> 00:39:03.630 ball of muscle outside of its normal position. 00:39:03.760 --> 00:39:06.420 The provider will never be able to push a contracted, 00:39:06.940 --> 00:39:08.840 rock -hard uterus back up through the narrow 00:39:08.840 --> 00:39:11.420 cervix. Exactly. You will have permanently trapped 00:39:11.420 --> 00:39:14.840 it outside the body. The text explicitly states 00:39:14.840 --> 00:39:17.019 that treatment frequently requires the administration 00:39:17.019 --> 00:39:20.059 of a uterine relaxant first. Medications like 00:39:20.059 --> 00:39:23.119 sublingual, nitroglycerin, tubutaline, or even 00:39:23.119 --> 00:39:25.719 magnesium sulfate. You purposefully relax the 00:39:25.719 --> 00:39:28.099 bleeding uterus. It sounds completely counterintuitive 00:39:28.099 --> 00:39:29.619 to everything we've learned today, but you have 00:39:29.619 --> 00:39:32.119 to turn the muscle into jelly so the provider 00:39:32.119 --> 00:39:34.400 can physically slide it back up into the pelvis. 00:39:34.730 --> 00:39:37.230 and the second it is safely back in its proper 00:39:37.230 --> 00:39:40.329 position inside the abdomen, then you slam it 00:39:40.329 --> 00:39:42.449 with the oxytocin and the mether gene to clamp 00:39:42.449 --> 00:39:45.010 it down and keep it there. That is such an incredible 00:39:45.010 --> 00:39:47.210 critical thinking point. Relax it to replace 00:39:47.210 --> 00:39:49.849 it, contract it to keep it. Finally, let's talk 00:39:49.849 --> 00:39:52.650 about uterine rupture versus dehescence. The 00:39:52.650 --> 00:39:55.110 text makes a very clear anatomical distinction 00:39:55.110 --> 00:39:57.050 between these two terms. The uterine rupture 00:39:57.050 --> 00:39:59.989 is a frank, complete tearing of the uterine wall. 00:40:00.670 --> 00:40:03.289 It creates a literal open window between the 00:40:03.289 --> 00:40:05.710 inside of the uterus and the abdominal cavity. 00:40:06.050 --> 00:40:08.449 A dehescence is a partial separation. The old 00:40:08.449 --> 00:40:11.349 C -section scar separates, but the outermost 00:40:11.349 --> 00:40:13.949 layer, the visceral peritoneum, remains intact. 00:40:14.250 --> 00:40:16.570 Dehescence is like a seam on your shirt tearing, 00:40:17.010 --> 00:40:19.650 but the inner lining holds. Rupture is a total 00:40:19.650 --> 00:40:22.670 blowout. Rupture has a significantly higher maternal 00:40:22.670 --> 00:40:24.809 and fetal mortality rate. And you must be able 00:40:24.809 --> 00:40:27.210 to recognize the concerning signs of a rupture, 00:40:27.250 --> 00:40:29.369 particularly in a patient who is attempting a 00:40:29.369 --> 00:40:31.909 vaginal birth after a previous C -section or 00:40:31.909 --> 00:40:35.269 a VBAC. Classic signs are a sudden onset of acute 00:40:35.269 --> 00:40:37.889 tearing abdominal pain, often described as feeling 00:40:37.889 --> 00:40:40.880 something give way. You will see massive maternal 00:40:40.880 --> 00:40:43.719 hemodynamic changes, meaning her heart rate spikes 00:40:43.719 --> 00:40:46.099 and her blood pressure drops. And the text notes 00:40:46.099 --> 00:40:49.500 a very specific, frightening physical finding. 00:40:50.400 --> 00:40:53.400 The loss of fetal station. Yes. If the baby's 00:40:53.400 --> 00:40:55.780 head was down low in the pelvis at a plus two 00:40:55.780 --> 00:40:58.599 station and suddenly the nurse doesn't exam and 00:40:58.599 --> 00:41:01.239 can no longer feel the head, it is because the 00:41:01.239 --> 00:41:04.260 uterus tore open and the fetus actually retracted 00:41:04.260 --> 00:41:06.900 upward, escaping into the mother's abdominal 00:41:06.900 --> 00:41:10.199 cavity. That is an immediate catastrophic surgical 00:41:10.199 --> 00:41:13.860 emergency. You're rushing to the OR for a crash 00:41:13.860 --> 00:41:16.559 c -section to save the baby's life and repair 00:41:16.559 --> 00:41:18.980 or remove the mother's uterus. Which brings us 00:41:18.980 --> 00:41:21.559 to a sobering point. We've spent the last hour 00:41:21.559 --> 00:41:24.159 discussing incredibly intense high -stakes medical 00:41:24.159 --> 00:41:26.480 management. We've talked about multi -liter hemorrhages, 00:41:26.900 --> 00:41:29.219 inside -out organs, and total systemic collapse. 00:41:29.460 --> 00:41:31.400 But the most important statistic in this entire 00:41:31.400 --> 00:41:33.559 text isn't about treating a hemorrhage, it is 00:41:33.559 --> 00:41:35.750 about preventing it. In the prevention section, 00:41:36.110 --> 00:41:38.889 the text explicitly states that active management 00:41:38.889 --> 00:41:41.590 of the third stage of labor, which involves early 00:41:41.590 --> 00:41:44.230 clamping, gentle cord traction by the provider, 00:41:44.789 --> 00:41:47.489 immediate bimanual massage, and prophylactic 00:41:47.489 --> 00:41:50.230 administration of oxytocin right as the baby's 00:41:50.230 --> 00:41:51.969 shoulder is delivered. Reduces the incidence 00:41:51.969 --> 00:41:55.989 of postpartum hemorrhage by up to 70%. 70%. Seven 00:41:55.989 --> 00:41:57.929 out of every ten life -threatening hemorrhages 00:41:57.929 --> 00:42:00.550 can be entirely prevented just by anticipating 00:42:00.550 --> 00:42:02.570 the muscle fatigue and helping the tourniquet 00:42:02.570 --> 00:42:05.230 clamp down early. That is the power of evidence 00:42:05.230 --> 00:42:08.130 -based nursing care. When you walk into a delivery 00:42:08.130 --> 00:42:10.469 room, you aren't just reacting to disasters, 00:42:10.690 --> 00:42:13.050 you are the architect of safety. We have covered 00:42:13.050 --> 00:42:15.710 massive ground today. We zoomed all the way in 00:42:15.710 --> 00:42:18.050 to look at the microscopic physiological changes 00:42:18.050 --> 00:42:20.610 of a narrowing pulse pressure. We explored the 00:42:20.610 --> 00:42:23.250 pharmacology of uteratonics and why an asthmatic 00:42:23.250 --> 00:42:25.650 patient can't have hemabate. We differentiated 00:42:25.650 --> 00:42:28.170 between the firm bleeding of a laceration and 00:42:28.170 --> 00:42:31.050 the boggy bleeding of atony. And we zoomed all 00:42:31.050 --> 00:42:33.750 the way out to manage the massive multidisciplinary 00:42:33.750 --> 00:42:37.530 response of a 1 .1 .1 transfusion protocol. If 00:42:37.530 --> 00:42:39.980 you can master this material, You aren't just 00:42:39.980 --> 00:42:42.739 going to pass the NCLE -X or ace your clinical 00:42:42.739 --> 00:42:45.400 exams. You are going to be the nurse who sees 00:42:45.400 --> 00:42:48.000 the vital sign dominoes falling long before the 00:42:48.000 --> 00:42:50.059 crash happens. You are going to be the nurse 00:42:50.059 --> 00:42:52.760 who advocates for the right medication at the 00:42:52.760 --> 00:42:54.880 right time and catches the mistake before it 00:42:54.880 --> 00:42:57.260 reaches the patient. But we want to leave you 00:42:57.260 --> 00:43:00.829 with one final thought to mull over. challenge, 00:43:00.829 --> 00:43:02.769 really, as you step out of this coaching session 00:43:02.769 --> 00:43:05.110 and into your clinical rotations. We just noted 00:43:05.110 --> 00:43:07.210 that active management of the third stage is 00:43:07.210 --> 00:43:10.190 a scientific fact. It prevents 70 % of these 00:43:10.190 --> 00:43:12.909 crises. So my question to you is this. If we 00:43:12.909 --> 00:43:15.670 know that a simple protocol of early oxytocin 00:43:15.670 --> 00:43:18.590 and gentle massage saves lives, how will you, 00:43:18.630 --> 00:43:21.210 as a primary bedside nurse, ensure that the standard 00:43:21.210 --> 00:43:23.849 of care is executed in every single delivery 00:43:23.849 --> 00:43:26.489 room you step into? How do you move from just 00:43:26.489 --> 00:43:28.969 knowing the textbook facts to being the vocal, 00:43:29.269 --> 00:43:31.769 confident advocate who ensures the safety standard 00:43:31.769 --> 00:43:34.530 is met, even when the room is chaotic or a provider 00:43:34.530 --> 00:43:37.170 is moving too fast? It is a profound responsibility, 00:43:37.170 --> 00:43:39.050 but after walking through this material today, 00:43:39.170 --> 00:43:41.150 I know you have the critical judgment required 00:43:41.150 --> 00:43:42.969 to handle it. Thank you for joining us for this 00:43:42.969 --> 00:43:46.070 intensive clinical deep dive. Take this knowledge. 00:43:46.469 --> 00:43:48.409 Carry these safety priorities directly to the 00:43:48.409 --> 00:43:50.949 bedside. Protect your patients and dominate those 00:43:50.949 --> 00:43:53.769 exams. We will catch you on the next deep dive.
