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 --> 00:00:43.859 room. Usually when we talk about a medical diagnosis, 00:00:44.380 --> 00:00:48.179 there's this expectation of absolute precision. 00:00:48.479 --> 00:00:51.200 Like engineering. Right, yeah, like a broken 00:00:51.200 --> 00:00:53.579 bone or something. Exactly. You break your arm, 00:00:53.679 --> 00:00:55.859 the x -ray shows that jagged white line, and 00:00:55.859 --> 00:00:57.420 the doctor just points and says, there it is. 00:00:57.859 --> 00:01:00.259 Well, it's a very comforting illusion. The idea 00:01:00.259 --> 00:01:02.960 that health care is always binary, like broken 00:01:02.960 --> 00:01:06.040 or not broken, sick or healthy. But then you 00:01:06.040 --> 00:01:08.599 step into the world of obstetric nursing, and 00:01:08.599 --> 00:01:10.920 suddenly that x -ray machine is entirely useless. 00:01:11.469 --> 00:01:13.590 I mean, we're looking at a clinical landscape 00:01:13.590 --> 00:01:16.310 that changes not just day to day, but minute 00:01:16.310 --> 00:01:17.989 to minute. Oh, absolutely. Because you don't 00:01:17.989 --> 00:01:19.909 just have one patient anymore, right? You have 00:01:19.909 --> 00:01:22.750 two. Two patients, yeah. Yeah. And the physiological 00:01:22.750 --> 00:01:25.129 shifts happening to both of them are incredibly 00:01:25.129 --> 00:01:28.430 dynamic. It is the absolute definition of high 00:01:28.430 --> 00:01:31.709 stakes, rapid fire clinical judgment. You literally 00:01:31.709 --> 00:01:34.569 have to anticipate a complication before the 00:01:34.569 --> 00:01:36.969 physical symptoms even fully manifest. Which 00:01:36.969 --> 00:01:39.390 is exactly why we are taking a slightly different 00:01:39.390 --> 00:01:42.079 approach for today's deep dive. We've got a massive 00:01:42.079 --> 00:01:44.540 stack of sources in front of us, clinical nursing 00:01:44.540 --> 00:01:47.799 textbooks, evidence -based OB protocols, and 00:01:47.799 --> 00:01:49.859 the latest research articles on the management 00:01:49.859 --> 00:01:52.560 of birth and the early postpartum period. Right. 00:01:52.560 --> 00:01:54.079 But we aren't just going to summarize them like 00:01:54.079 --> 00:01:56.079 a table of contents. Today, we are acting as 00:01:56.079 --> 00:01:59.920 your elite OB nursing clinical mentors. Yes. 00:02:00.200 --> 00:02:03.500 We are applying the PREO principle to all this 00:02:03.500 --> 00:02:06.780 material. We are hunting for that 20 % of high 00:02:06.780 --> 00:02:08.960 yield info that is going to give you 80 % of 00:02:08.960 --> 00:02:11.650 your exam points. And honestly, more importantly, 00:02:12.050 --> 00:02:14.469 the insights that will actually make you a safe, 00:02:14.729 --> 00:02:17.689 effective nurse at the bedside. Exactly. No fluff. 00:02:18.270 --> 00:02:21.030 We're focusing on priority interventions, those 00:02:21.030 --> 00:02:23.169 classic clinical traps that instructors love 00:02:23.169 --> 00:02:26.050 to test, and the absolute non -negotiables of 00:02:26.050 --> 00:02:28.430 maternal and fetal safety. So to do that, we 00:02:28.430 --> 00:02:30.590 need to pick up the narrative right at the end 00:02:30.590 --> 00:02:33.409 of the first stage of labor. Right. The patient 00:02:33.409 --> 00:02:35.689 has been having contractions for hours, the cervix 00:02:35.689 --> 00:02:37.770 is finally opening, and we are entering the second 00:02:37.770 --> 00:02:40.860 stage. Which is clinically defined as complete 00:02:40.860 --> 00:02:43.919 dilation at 10 centimeters until the baby is 00:02:43.919 --> 00:02:45.800 actually delivered. And this is where we hit 00:02:45.800 --> 00:02:48.340 our first major clinical trap, right? Because 00:02:48.340 --> 00:02:50.879 a patient might look at you and say, I feel an 00:02:50.879 --> 00:02:53.939 overwhelming urge to push. Yes. And a lot of 00:02:53.939 --> 00:02:56.520 people, especially students, assume that if the 00:02:56.520 --> 00:02:59.259 body is signaling to push, the nurse should just 00:02:59.259 --> 00:03:02.280 say, OK, go for it. But you must verify their 00:03:02.280 --> 00:03:04.960 dilation first. Because the cervix is essentially 00:03:04.960 --> 00:03:07.580 a doorway. I mean, think about moving a massive 00:03:07.580 --> 00:03:09.939 couch. Oh, I love this analogy. You wouldn't 00:03:09.939 --> 00:03:12.039 try to shove a couch through a doorway that is 00:03:12.039 --> 00:03:15.060 only like 80 % open. If you force it, you don't 00:03:15.060 --> 00:03:17.159 just get stuck. You rip the door frame right 00:03:17.159 --> 00:03:19.360 out of the wall. It's perfect because it highlights 00:03:19.360 --> 00:03:22.240 the mechanical reality of the pelvis. If a patient 00:03:22.240 --> 00:03:25.599 actively pushes before they are fully at 10 centimeters, 00:03:26.300 --> 00:03:28.300 the cervix is still partially in the way. Right. 00:03:28.669 --> 00:03:31.750 So the baby's hard skull gets rammed against 00:03:31.750 --> 00:03:34.550 that delicate cervical tissue, literally pinning 00:03:34.550 --> 00:03:36.710 it against the mother's pubic bone. So the tissue 00:03:36.710 --> 00:03:38.629 just gets trapped? It gets trapped, it loses 00:03:38.629 --> 00:03:41.349 blood flow, and it swells. And that swelling 00:03:41.349 --> 00:03:43.770 is called cervical edema. Which makes it even 00:03:43.770 --> 00:03:47.210 harder to dilate, right? Ironically, yes. A swollen 00:03:47.210 --> 00:03:50.210 cervix becomes thicker and even less likely to 00:03:50.210 --> 00:03:53.189 dilate. Not to mention, you are risking severe 00:03:53.189 --> 00:03:56.069 cervical lacerations for the mother and dangerous 00:03:56.069 --> 00:03:58.560 compression on the fetal head. Wow. So the rule 00:03:58.560 --> 00:04:01.960 is never let the patient push before 10 centimeters. 00:04:02.180 --> 00:04:04.039 Okay, let me play devil's advocate here though. 00:04:04.599 --> 00:04:07.699 What if a patient is confirmed to be 10 centimeters 00:04:07.699 --> 00:04:10.639 dilated? The doorway is completely open but they 00:04:10.639 --> 00:04:13.340 have an epidural and they literally feel no urge 00:04:13.340 --> 00:04:15.560 to push at all. That happens all the time. Do 00:04:15.560 --> 00:04:17.579 we just start cheering and forcing them to bear 00:04:17.579 --> 00:04:19.819 down anyway because the textbook says it's the 00:04:19.819 --> 00:04:22.089 second stage? That is a very common scenario 00:04:22.089 --> 00:04:24.709 and forcing them to push immediately is actually 00:04:24.709 --> 00:04:27.250 an outdated practice. This is where we look at 00:04:27.250 --> 00:04:29.990 what is expected versus what is concerning. Okay. 00:04:30.370 --> 00:04:32.990 It is perfectly safe and strongly supported by 00:04:32.990 --> 00:04:35.670 evidence to practice something called laboring 00:04:35.670 --> 00:04:38.990 down. Meaning we just wait. Yeah, we allow passive 00:04:38.990 --> 00:04:41.329 fetal descent. You can delay pushing for up to 00:04:41.329 --> 00:04:44.149 two hours. The uterus is still naturally contracting. 00:04:44.310 --> 00:04:46.990 Gravity is still doing its job. And the fetus 00:04:46.990 --> 00:04:49.089 is passively descending and rotating through 00:04:49.089 --> 00:04:51.129 the birth canal. All while the patient is just 00:04:51.129 --> 00:04:53.930 resting. Exactly. When the baby descends low 00:04:53.930 --> 00:04:56.529 enough to trigger the natural bearing down reflex 00:04:56.529 --> 00:04:58.850 or when the two hours are up, then you start 00:04:58.850 --> 00:05:01.449 active pushing. You save incredible amounts of 00:05:01.449 --> 00:05:03.579 maternal energy this way. That makes so much 00:05:03.579 --> 00:05:06.959 sense. I mean, why exhaust the patient if the 00:05:06.959 --> 00:05:08.800 uterine muscles and gravity can do the heavy 00:05:08.800 --> 00:05:11.839 lifting? Right. Speaking of gravity, let's talk 00:05:11.839 --> 00:05:14.779 about positioning, because the media gets this 00:05:14.779 --> 00:05:18.500 wildly wrong. If you watch television, every 00:05:18.500 --> 00:05:21.199 single person giving birth is lying. completely 00:05:21.199 --> 00:05:23.579 flat on their back, feet in the air. That flat 00:05:23.579 --> 00:05:26.839 supine position is a massive exam trap. And honestly, 00:05:27.040 --> 00:05:29.420 it is arguably the worst physiological position 00:05:29.420 --> 00:05:31.800 you can put a laboring patient in. Why though? 00:05:31.939 --> 00:05:34.600 If it's so terrible, how did it become the default 00:05:34.600 --> 00:05:37.279 image of childbirth? It became the default because 00:05:37.279 --> 00:05:39.420 it's convenient for the provider's line of sight, 00:05:39.500 --> 00:05:42.079 not because it's beneficial for the physiology 00:05:42.079 --> 00:05:44.939 of birth. When a pregnant patient lies flat on 00:05:44.939 --> 00:05:47.879 their back, Think about the sheer weight of a 00:05:47.879 --> 00:05:50.839 full -term uterus. The baby, the amniotic fluid, 00:05:51.180 --> 00:05:53.420 the placenta. That's a lot of weight. All of 00:05:53.420 --> 00:05:55.920 that weight presses down directly on the inferior 00:05:55.920 --> 00:05:58.620 vena cava and the descending aorta, which run 00:05:58.620 --> 00:06:01.500 right along the spine. So you're literally kinking 00:06:01.500 --> 00:06:04.939 the hose. Yes. We call it aorta -caval compression. 00:06:05.759 --> 00:06:08.379 The heavy uterus crushes the main vein, bringing 00:06:08.379 --> 00:06:10.540 blood back to the mother's heart. So her blood 00:06:10.540 --> 00:06:13.329 pressure drops. Maternal cardiac output drops 00:06:13.329 --> 00:06:15.970 instantly, her blood pressure plummets, and as 00:06:15.970 --> 00:06:18.689 a direct result, perfusion to the placenta is 00:06:18.689 --> 00:06:21.329 severely compromised. You will see the fetal 00:06:21.329 --> 00:06:23.470 heart rate drop on the monitor very quickly because 00:06:23.470 --> 00:06:26.310 the baby is being deprived of oxygen. That is 00:06:26.310 --> 00:06:28.529 terrifying. Okay, so your memory anchor for this 00:06:28.529 --> 00:06:31.569 is simple. Gravity is your co -pilot, and the 00:06:31.569 --> 00:06:34.870 supine position is a crash landing. Do not crash 00:06:34.870 --> 00:06:37.639 the plane. Keep them upright. squatting, hands 00:06:37.639 --> 00:06:39.759 and knees, or at the very least a side -lying 00:06:39.759 --> 00:06:42.879 lateral position. Upright positions don't just 00:06:42.879 --> 00:06:45.180 fix the blood flow, they actually shift the pelvic 00:06:45.180 --> 00:06:47.560 bones to increase the physical dimensions of 00:06:47.560 --> 00:06:50.259 the maternal pelvis. Giving the baby more room 00:06:50.259 --> 00:06:53.660 to maneuver. Exactly. So we use gravity, we get 00:06:53.660 --> 00:06:55.959 the baby out, and we enter the third stage of 00:06:55.959 --> 00:06:58.680 labor. Everyone in the room is crying, the lighting 00:06:58.680 --> 00:07:01.259 is beautiful, the baby is crying. It feels like 00:07:01.259 --> 00:07:03.040 the finish line. It feels like a celebration, 00:07:03.259 --> 00:07:07.680 yeah. But clinically, Your radar as a nurse needs 00:07:07.680 --> 00:07:10.160 to be at its absolute highest right now. Really? 00:07:10.519 --> 00:07:13.000 The maternal danger spikes significantly the 00:07:13.000 --> 00:07:16.060 moment that baby is out. The third stage is entirely 00:07:16.060 --> 00:07:18.620 about delivering the placenta safely and preventing 00:07:18.620 --> 00:07:21.240 a catastrophic hemorrhage. We use a protocol 00:07:21.240 --> 00:07:23.740 called active management of the third stage of 00:07:23.740 --> 00:07:26.139 labor. Which introduces a really fascinating 00:07:26.139 --> 00:07:28.459 paradox in our pharmacology, I think. The primary 00:07:28.459 --> 00:07:31.160 medication we use during this stage is oxytocin. 00:07:31.529 --> 00:07:34.329 But wait, we routinely give oxytocin antipartum 00:07:34.329 --> 00:07:36.750 to induce labor and force the baby out. Right. 00:07:37.050 --> 00:07:38.990 Why on earth are we giving the exact same drug 00:07:38.990 --> 00:07:41.189 now that the baby is already born? This requires 00:07:41.189 --> 00:07:43.509 a total shift in how you think about medications. 00:07:43.629 --> 00:07:45.730 You have to stop thinking of oxytocin as just 00:07:45.730 --> 00:07:47.990 a birth -inducing drug and start thinking of 00:07:47.990 --> 00:07:50.470 it as a relentless muscle constrictor. Okay, 00:07:50.529 --> 00:07:52.790 so it just squeezes. What it achieves depends 00:07:52.790 --> 00:07:56.110 entirely on the context of the uterus. Before 00:07:56.110 --> 00:07:58.439 birth, Constricting the uterine muscle pushes 00:07:58.439 --> 00:08:02.040 the baby down and opens the cervix. But postpartum, 00:08:02.180 --> 00:08:04.620 once the placenta detaches from the uterine wall, 00:08:04.879 --> 00:08:08.100 it leaves behind a massive open wound inside 00:08:08.100 --> 00:08:11.800 the uterus. Just expose bleeding blood vessels. 00:08:12.220 --> 00:08:14.819 Exactly. Because the placenta was the blood supply. 00:08:15.120 --> 00:08:16.879 You rip it off, the pipes are still flowing. 00:08:17.120 --> 00:08:19.379 And I'm guessing the human body doesn't have 00:08:19.379 --> 00:08:22.000 traditional scabs large enough to instantly cover 00:08:22.000 --> 00:08:25.259 that kind of wound. It doesn't. Instead, the 00:08:25.259 --> 00:08:27.860 uterine muscle fibers themselves act as living 00:08:27.860 --> 00:08:31.680 ligatures. When we administer postpartum oxytocin, 00:08:32.019 --> 00:08:34.460 we are forcing that massive uterine muscle to 00:08:34.460 --> 00:08:37.059 clamp down violently hard. Oh, so it pinches 00:08:37.059 --> 00:08:39.539 them shut. Right, that clamping action literally 00:08:39.539 --> 00:08:41.980 pinches those bleeding blood vessels shut. It 00:08:41.980 --> 00:08:44.580 acts as an internal tourniquet to prevent postpartum 00:08:44.580 --> 00:08:48.259 hemorrhage. Okay. But any good exam or any real 00:08:48.259 --> 00:08:50.500 -world clinical crisis isn't going to let you 00:08:50.500 --> 00:08:52.720 rely on just one drug. Your instructor is going 00:08:52.720 --> 00:08:54.639 to want to know what happens if the oxytocin 00:08:54.639 --> 00:08:56.399 isn't working or if the bleeding won't stop. 00:08:56.519 --> 00:08:58.600 Oh, they definitely will test that. Let's drill 00:08:58.600 --> 00:09:00.960 into the alternative uterotonics, because they 00:09:00.960 --> 00:09:04.179 come with some intense contraindications. First 00:09:04.179 --> 00:09:07.740 up, methylurganavine. Methylurganavine is a powerful 00:09:07.740 --> 00:09:11.740 drug, but it is an absolute no for any patient 00:09:11.740 --> 00:09:14.340 with hypertension. Wait. Why does a uterine drug 00:09:14.340 --> 00:09:16.159 care about blood pressure? Because it doesn't 00:09:16.159 --> 00:09:19.240 just target the uterus. It causes widespread 00:09:19.240 --> 00:09:22.279 systemic vasoconstriction of smooth muscle throughout 00:09:22.279 --> 00:09:24.899 the entire body. Oh, wow. So if your patient 00:09:24.899 --> 00:09:28.080 already has high blood pressure from, say, preeclampsia, 00:09:28.179 --> 00:09:30.120 and you give them methyl organovine, their blood 00:09:30.120 --> 00:09:32.720 vessels clamp down everywhere, their blood pressure 00:09:32.720 --> 00:09:35.539 will experience a massive life -threatening spike. 00:09:35.580 --> 00:09:37.580 They could stroke out. They could easily stroke 00:09:37.580 --> 00:09:40.080 out right there on the table. So methyl organovine 00:09:40.080 --> 00:09:43.929 equals NO for hypertension. What about carboprost? 00:09:44.309 --> 00:09:47.269 Carboprost is a prostaglandin. It's incredibly 00:09:47.269 --> 00:09:49.629 effective at stimulating the myometrium, but 00:09:49.629 --> 00:09:52.950 the classic trap here is asthma. Asthma. You 00:09:52.950 --> 00:09:55.250 do not give carboprost to patients with active 00:09:55.250 --> 00:09:57.769 pulmonary disease because one of its major adverse 00:09:57.769 --> 00:10:00.529 effects is severe bronchospasm. You might stop 00:10:00.529 --> 00:10:02.629 the bleeding, but you'll close off their airway. 00:10:02.929 --> 00:10:05.830 Fix one problem, create a deadlier one. Got it. 00:10:06.129 --> 00:10:09.789 And the last major one is mesoprostal. Also, 00:10:09.850 --> 00:10:12.450 a prostaglandin, frequently given rectally for 00:10:12.450 --> 00:10:14.850 hemorrhage. The main contraindication you'll 00:10:14.850 --> 00:10:17.750 see tested is simply a known hypersensitivity 00:10:17.750 --> 00:10:20.350 or allergy, but it's vital to know it belongs 00:10:20.350 --> 00:10:22.490 in your hemorrhage toolkit. Now, while the nurse 00:10:22.490 --> 00:10:24.850 is managing the uteratonics and monitoring the 00:10:24.850 --> 00:10:27.490 mother's bleeding, there's a simultaneous process 00:10:27.490 --> 00:10:29.970 happening with the umbilical cord. The sources 00:10:29.970 --> 00:10:33.090 emphasize delayed cord clamping. We aren't just 00:10:33.090 --> 00:10:35.399 cutting it immediately anymore. Waiting 30 to 00:10:35.399 --> 00:10:38.019 60 seconds to clamp the cord is expected practice 00:10:38.019 --> 00:10:40.480 now. During that minute, a significant volume 00:10:40.480 --> 00:10:42.980 of blood from the placenta pulses into the newborn. 00:10:43.179 --> 00:10:45.539 Which is good, right? Very good. It dramatically 00:10:45.539 --> 00:10:48.460 increases their hemoglobin, builds their iron 00:10:48.460 --> 00:10:51.039 stores, and actually improves long -term cognitive 00:10:51.039 --> 00:10:54.480 development. But every intervention has a downstream 00:10:54.480 --> 00:10:57.519 effect. If we are giving the baby all this extra 00:10:57.519 --> 00:10:59.639 blood, what happens when those red blood cells 00:10:59.639 --> 00:11:02.139 eventually reach the end of their lifespan and 00:11:02.139 --> 00:11:05.049 break down? That is the crucial clinical connection. 00:11:05.789 --> 00:11:08.129 When red blood cells break down, a byproduct 00:11:08.129 --> 00:11:11.029 called bilirubin is released. The newborn's liver 00:11:11.029 --> 00:11:13.690 has to process that bilirubin. But their liver 00:11:13.690 --> 00:11:16.529 is immature. Exactly. Because we gave them an 00:11:16.529 --> 00:11:19.269 extra large dose of red blood cells, their immature 00:11:19.269 --> 00:11:22.490 liver has to work overtime. The direct consequence 00:11:22.490 --> 00:11:24.929 is a much higher risk for hyper bilirubinemia, 00:11:25.230 --> 00:11:28.529 which presents as jaundice. So more blood equals 00:11:28.529 --> 00:11:31.409 more bilirubin. So the priority action is to 00:11:31.409 --> 00:11:34.090 monitor that newborn's skin and sclera for a 00:11:34.090 --> 00:11:37.740 yellow tint in the coming days, which... perfectly 00:11:37.740 --> 00:11:40.000 bridges us to the baby. We are now in the golden 00:11:40.000 --> 00:11:42.379 hour. The baby is out, ideally skin to skin on 00:11:42.379 --> 00:11:44.759 the mother's chest, transitioning to Extraterine 00:11:44.759 --> 00:11:47.139 Life. And this transition is quantified by the 00:11:47.139 --> 00:11:49.620 APG error score measured at exactly one minute 00:11:49.620 --> 00:11:51.639 and five minutes after birth. I have to admit, 00:11:51.879 --> 00:11:54.600 APG error feels like such a harsh snap judgment 00:11:54.600 --> 00:11:56.600 of a brand new human. It's out of 10 points. 00:11:56.860 --> 00:11:59.460 If a baby scores a six, is the team initiating 00:11:59.460 --> 00:12:01.740 a code blue? Not necessarily. And understanding 00:12:01.740 --> 00:12:04.139 the scoring tiers is what separates a novice 00:12:04.139 --> 00:12:07.539 from an expert. The APGA measures five components, 00:12:08.039 --> 00:12:11.500 heart rate, breathing effort, muscle tone, reflex 00:12:11.500 --> 00:12:14.159 irritability, and color. You get a zero, one, 00:12:14.159 --> 00:12:16.950 or two in each category. So a perfect 10 is actually 00:12:16.950 --> 00:12:20.090 pretty rare. Very rare. A score of 7 to 10 is 00:12:20.090 --> 00:12:22.389 considered normal. The baby is transitioning. 00:12:22.490 --> 00:12:25.110 Well, just keep monitoring. A score of 4 to 6 00:12:25.110 --> 00:12:27.289 is fair. That's the middle ground. Right. It 00:12:27.289 --> 00:12:29.509 doesn't mean full CPR, but it does mean the baby 00:12:29.509 --> 00:12:31.690 is struggling and needs intervention, usually 00:12:31.690 --> 00:12:35.029 suctioning the airway to clear mucus and vigorous 00:12:35.029 --> 00:12:37.570 tactile stimulation. Like you're literally rubbing 00:12:37.570 --> 00:12:39.549 their back or flicking the soles of their feet 00:12:39.549 --> 00:12:41.509 to remind their nervous system to breathe. Yes, 00:12:41.509 --> 00:12:43.730 you are actively waking up their respiratory 00:12:43.730 --> 00:12:46.490 drive. Now, if the score zero to three that indicates 00:12:46.490 --> 00:12:50.169 severe distress and that is when immediate full 00:12:50.169 --> 00:12:53.129 resuscitation efforts begin. Okay there is a 00:12:53.129 --> 00:12:56.049 massive exam trap buried in the APGR specifically 00:12:56.049 --> 00:12:58.429 around the color category. Let's talk about the 00:12:58.429 --> 00:13:01.649 blue hands because if I see a blue patient my 00:13:01.649 --> 00:13:04.169 instinct is to panic. And that instinct will 00:13:04.169 --> 00:13:07.169 cause you to overreact during a delivery. Almost 00:13:07.169 --> 00:13:09.929 all newborns lose a point for color scoring a 00:13:09.929 --> 00:13:12.429 one instead of a two because of a condition called 00:13:12.429 --> 00:13:15.120 acrosynosis. Acrosynosis? What is that? This 00:13:15.120 --> 00:13:17.320 is when the baby's trunk and face are a healthy 00:13:17.320 --> 00:13:19.860 pink, but their hands and feet are distinctly 00:13:19.860 --> 00:13:22.679 blue. Why does that happen? Because peripheral 00:13:22.679 --> 00:13:25.980 circulation in a newborn is sluggish. Their body 00:13:25.980 --> 00:13:29.019 is smartly prioritizing oxygenated blood to the 00:13:29.019 --> 00:13:31.740 brain, heart, and lungs. The hands and feet are 00:13:31.740 --> 00:13:34.679 the lowest priority. Acrosinosis is completely 00:13:34.679 --> 00:13:37.419 benign and totally expected in the first 24 hours. 00:13:37.700 --> 00:13:41.360 So blue hands and feet. Expected finding. Documented 00:13:41.360 --> 00:13:43.299 and move on. But the distinction here is central 00:13:43.299 --> 00:13:46.419 cyanosis. If the baby is blue around the mouth, 00:13:46.700 --> 00:13:49.419 the lips, or the central chest, that is a hallmark 00:13:49.419 --> 00:13:52.820 of severe hypoxia and respiratory distress. That's 00:13:52.820 --> 00:13:54.960 the emergency. That is an absolute emergency 00:13:54.960 --> 00:13:57.480 and a priority to report immediately. Acrosinosis 00:13:57.480 --> 00:13:59.860 is normal. Central cyanosis is a crisis. Got 00:13:59.860 --> 00:14:03.039 it. Now, as part of this golden hour, the nurse 00:14:03.039 --> 00:14:06.179 is administering two very specific newborn medications. 00:14:06.720 --> 00:14:09.539 We do erythromycin Ionamin and a vitamin K shot. 00:14:09.690 --> 00:14:12.730 Now, I understand the eye ointment we give erythromycin 00:14:12.730 --> 00:14:16.009 to prevent neonatal ophthalmia, basically protecting 00:14:16.009 --> 00:14:18.490 the baby's eyes from bacteria like gonorrhea 00:14:18.490 --> 00:14:20.450 or chlamydia they might have encountered in the 00:14:20.450 --> 00:14:22.429 birth canal, which can cause permanent blindness. 00:14:22.610 --> 00:14:25.049 It's pure prophylaxis. Right. But the vitamin 00:14:25.049 --> 00:14:27.570 K, the vitamin A deodorant, we give it intramuscularly. 00:14:28.190 --> 00:14:30.450 Why are we stabbing a one -hour -old baby with 00:14:30.450 --> 00:14:33.169 a needle? Why not just let them get vitamin K 00:14:33.169 --> 00:14:35.740 naturally? or give it orally. This is one of 00:14:35.740 --> 00:14:38.460 my favorite physiological mechanisms. It prevents 00:14:38.460 --> 00:14:41.639 vitamin K deficiency bleeding, which can cause 00:14:41.639 --> 00:14:44.279 catastrophic brain bleeds in newborns. But why 00:14:44.279 --> 00:14:46.159 are they deficient in the first place? Think 00:14:46.159 --> 00:14:49.799 about how adult bodies get vitamin K. A large 00:14:49.799 --> 00:14:52.559 portion of it is synthesized by the normal, healthy 00:14:52.559 --> 00:14:55.320 bacteria living in our gut. But a newborn hasn't 00:14:55.320 --> 00:14:57.779 eaten anything yet. Exactly. A newborn's gut 00:14:57.779 --> 00:15:00.519 is completely sparrow. They have zero gut flora. 00:15:00.679 --> 00:15:02.960 Because they don't have the bacteria, they cannot 00:15:02.960 --> 00:15:05.899 synthesize their own vitamin K. And without vitamin 00:15:05.899 --> 00:15:08.659 K, the liver cannot produce the essential clotting 00:15:08.659 --> 00:15:12.419 factors, specifically factors 2, Z -8, IX, and 00:15:12.419 --> 00:15:16.840 X. Wow. Sterile gut means no vitamin K. No vitamin 00:15:16.840 --> 00:15:19.259 K means the blood literally lacks the chemical 00:15:19.259 --> 00:15:21.899 ingredients to form a clot. Right. If they have 00:15:21.899 --> 00:15:24.360 even a minor internal bleed from the trauma of 00:15:24.360 --> 00:15:26.460 birth, they could bleed to death because the 00:15:26.460 --> 00:15:29.639 clotting cascade is broken. The IM shot bypasses 00:15:29.639 --> 00:15:32.360 the sterile gut and gives them the vitamin directly 00:15:32.360 --> 00:15:35.360 so their blood can clot while their gut bacteria 00:15:35.360 --> 00:15:37.779 slowly develops over the next few days. That 00:15:37.779 --> 00:15:41.159 causality is so clear. OK, the baby is stabilized, 00:15:41.379 --> 00:15:44.019 medicated and doing well. But the mother's journey 00:15:44.019 --> 00:15:46.240 is far from over. Let's look at the first one 00:15:46.240 --> 00:15:48.759 to two hours postpartum, which the sources designate 00:15:48.759 --> 00:15:51.220 as the fourth stage of labor. This is the critical 00:15:51.220 --> 00:15:53.460 recovery window, and the high -yield core here 00:15:53.460 --> 00:15:56.480 is the fundal assessment. The fundus is the rounded 00:15:56.480 --> 00:15:58.980 top portion of the uterus. For the first hour 00:15:58.980 --> 00:16:01.299 postpartum, the nurse must palpate and assess 00:16:01.299 --> 00:16:03.879 that fundus every 15 minutes. When I press on 00:16:03.879 --> 00:16:06.220 a postpartum abdomen, what exactly am I hoping 00:16:06.220 --> 00:16:07.980 to feel? Is this supposed to feel like a water 00:16:07.980 --> 00:16:10.100 balloon? You want it to feel like a hard grapefruit. 00:16:10.340 --> 00:16:12.759 It should be firm, perfectly midline in the abdomen, 00:16:13.139 --> 00:16:15.320 and located roughly halfway between the pubic 00:16:15.320 --> 00:16:17.539 bone and the belly button. And if it's firm, 00:16:17.759 --> 00:16:20.639 that's good. Yes. If it is firm, it means those 00:16:20.639 --> 00:16:22.879 muscle fibers we talked about earlier are clamped 00:16:22.879 --> 00:16:25.299 down tightly, acting as that tourniquet. Which 00:16:25.299 --> 00:16:28.480 brings us to the two biggest postpartum red flags 00:16:28.480 --> 00:16:31.360 that will absolutely be on your exams. Trap number 00:16:31.360 --> 00:16:34.679 one. the boggy uterus. If you palpate the abdomen 00:16:34.679 --> 00:16:37.519 and the uterus feels soft mushy or boggy like 00:16:37.519 --> 00:16:40.879 a wet sponge that is uterine adenine. The muscle 00:16:40.879 --> 00:16:43.639 has fatigued and relaxed and if the muscle relaxes 00:16:43.639 --> 00:16:45.639 the tourniquet is off the blood vessels open 00:16:45.639 --> 00:16:48.179 wide and your patient is actively hemorrhaging 00:16:48.179 --> 00:16:53.080 inside. So what is the immediate priority nursing 00:16:53.080 --> 00:16:55.399 action? I mean you don't leave the room to call 00:16:55.399 --> 00:16:57.490 the doctor right? Do not leave the patient. Your 00:16:57.490 --> 00:17:00.129 immediate action is fundal massage. You place 00:17:00.129 --> 00:17:02.830 one hand just above the pubic bone to support 00:17:02.830 --> 00:17:04.750 the lower segment of the uterus, preventing it 00:17:04.750 --> 00:17:07.049 from prolapsing, and you use your other hand 00:17:07.049 --> 00:17:09.930 to vigorously massage the boggy fundus. Just 00:17:09.930 --> 00:17:11.930 wake the muscle up. You are using mechanical 00:17:11.930 --> 00:17:14.430 friction to physically irritate and stimulate 00:17:14.430 --> 00:17:16.769 the muscle fibers into contracting again. You 00:17:16.769 --> 00:17:18.589 become the tourniquet until the muscle wakes 00:17:18.589 --> 00:17:23.309 up. Okay, trap number two, the deviated uterus. 00:17:24.410 --> 00:17:27.529 You assess the fundus. It might actually feel 00:17:27.529 --> 00:17:30.970 firm, but it's not midline. It shifted way over 00:17:30.970 --> 00:17:32.930 to the right or left side of the abdomen. If 00:17:32.930 --> 00:17:35.029 the uterus is deviated, it almost always means 00:17:35.029 --> 00:17:37.509 the patient's bladder is completely full. See, 00:17:37.529 --> 00:17:40.049 I always struggled with this anatomically. The 00:17:40.049 --> 00:17:42.730 uterus just held a seven -pound baby and a liter 00:17:42.730 --> 00:17:45.470 of fluid. It's a massive heavy organ. Correct. 00:17:45.690 --> 00:17:47.289 Are you telling me a little bit of urine in the 00:17:47.289 --> 00:17:49.509 bladder is physically strong enough to push the 00:17:49.509 --> 00:17:51.940 entire uterus out of the way? It is because of 00:17:51.940 --> 00:17:54.359 how they sit together in the pelvis. The bladder 00:17:54.359 --> 00:17:57.220 is positioned directly anterior and slightly 00:17:57.220 --> 00:17:59.859 inferior to the flexible lower segment of the 00:17:59.859 --> 00:18:02.819 uterus. Remember, the mother just received liters 00:18:02.819 --> 00:18:05.680 of 5E fluids during labor. As that bladder fills 00:18:05.680 --> 00:18:07.819 up with urine, it balloons outward and acts like 00:18:07.819 --> 00:18:10.200 a wedge, physically pushing the uterus up and 00:18:10.200 --> 00:18:12.079 usually deflecting it to the right side. But 00:18:12.079 --> 00:18:14.579 why is that a medical emergency? Because a displaced, 00:18:14.960 --> 00:18:17.799 stretched uterus cannot contract effectively. 00:18:18.109 --> 00:18:21.230 The full bladder is physically blocking the muscle 00:18:21.230 --> 00:18:23.809 from clamping down. So a full bladder directly 00:18:23.809 --> 00:18:26.190 causes uterine adenine, which directly causes 00:18:26.190 --> 00:18:28.869 a hemorrhage. So if it's deviated, the immediate 00:18:28.869 --> 00:18:31.730 action is to empty the bladder, assist them to 00:18:31.730 --> 00:18:34.450 the bathroom, put them on a bedpan, or straight 00:18:34.450 --> 00:18:36.890 catheterize them if they cannot void. Your memory 00:18:36.890 --> 00:18:41.269 anchor here is boggy. Massage it. Deviated. Empty 00:18:41.269 --> 00:18:43.839 it. And while we are on the topic of hemorrhage, 00:18:44.299 --> 00:18:46.539 the sources make a massive point about how we 00:18:46.539 --> 00:18:48.940 actually measure blood loss. Quantitative blood 00:18:48.940 --> 00:18:52.140 loss, or QBL. The days of a nurse looking at 00:18:52.140 --> 00:18:53.900 a bloody pad and guessing, oh, it looks like 00:18:53.900 --> 00:18:56.500 about 300 milliliters, are over. Because it's 00:18:56.500 --> 00:18:59.079 inaccurate. Eyeballing blood loss is notoriously 00:18:59.079 --> 00:19:01.240 inaccurate and leads to delayed hemorrhage treatment. 00:19:01.380 --> 00:19:03.720 So we weigh it. You weigh the blood -soaked pads 00:19:03.720 --> 00:19:06.160 on a gram scale, and you subtract the dry weight 00:19:06.160 --> 00:19:08.539 of the pad. The mathematical conversion is one 00:19:08.539 --> 00:19:11.349 -to -one. One gram of weight equals one milliliter 00:19:11.349 --> 00:19:14.069 of blood. If that total blood loss exceeds a 00:19:14.069 --> 00:19:15.990 thousand milliliters, regardless of whether it 00:19:15.990 --> 00:19:18.390 was a vaginal or cesarean birth, it is officially 00:19:18.390 --> 00:19:20.650 classified as a postpartum hemorrhage. We have 00:19:20.650 --> 00:19:22.869 covered an immense amount of physiology today. 00:19:23.089 --> 00:19:25.970 Let's bring it all together. Imagine a new L 00:19:25.970 --> 00:19:28.950 &D nurse walking onto the floor for their very 00:19:28.950 --> 00:19:32.549 first shift tomorrow. What is the mental checklist, 00:19:33.109 --> 00:19:35.690 the absolute non -negotiables playing on loop 00:19:35.690 --> 00:19:38.569 in their head? First, they are verifying dilation. 00:19:38.700 --> 00:19:40.720 They know that letting a patient push before 00:19:40.720 --> 00:19:43.339 10 centimeters guarantees cervical tearing and 00:19:43.339 --> 00:19:46.759 fetal distress. Second, they are constantly analyzing 00:19:46.759 --> 00:19:49.460 positioning. They know the supine position causes 00:19:49.460 --> 00:19:51.720 aortic ovule compression, so they are utilizing 00:19:51.720 --> 00:19:54.839 gravity and lateral positions to keep fetal perfusion 00:19:54.839 --> 00:19:57.359 high. Right. And they aren't panicking over blue 00:19:57.359 --> 00:20:00.319 hands. They know acrocyanosis is a normal newborn 00:20:00.319 --> 00:20:02.740 finding, but they are sprinting to the bedside 00:20:02.740 --> 00:20:05.079 if they see central cyanosis around the baby's 00:20:05.079 --> 00:20:07.079 mouth. They know their uterotonic is cold. If 00:20:07.079 --> 00:20:09.559 a patient is hypertensive, they know methylurganavine 00:20:09.559 --> 00:20:11.480 is off the table because of the stroke risk. 00:20:11.660 --> 00:20:13.720 And finally, when they do those postpartum checks, 00:20:14.000 --> 00:20:15.740 they know exactly what their hands are telling 00:20:15.740 --> 00:20:19.339 them. is boggy, they massage it. If it's deviated, 00:20:19.440 --> 00:20:22.099 they empty the bladder. It's a really solid clinical 00:20:22.099 --> 00:20:25.420 armor to walk onto the unit with. But before 00:20:25.420 --> 00:20:27.680 we wrap up this deep dive, there's one piece 00:20:27.680 --> 00:20:30.000 of data in these sources that doesn't fit neatly 00:20:30.000 --> 00:20:32.829 into a pharmacology chart. but it is just as 00:20:32.829 --> 00:20:35.289 critical to maternal survival. It is, and it 00:20:35.289 --> 00:20:37.509 challenges the way we view medical interventions 00:20:37.509 --> 00:20:41.009 entirely. We spend years memorizing stages, medications, 00:20:41.190 --> 00:20:44.789 and APGA scores. But the source material explicitly 00:20:44.789 --> 00:20:47.029 highlights the reality of maternal mortality, 00:20:47.470 --> 00:20:50.470 particularly how, in the U .S., Black maternal 00:20:50.470 --> 00:20:53.190 clients face a significantly higher risk of death 00:20:53.190 --> 00:20:55.750 from pregnancy -related complications. But the 00:20:55.750 --> 00:20:58.269 textbook doesn't just state the problem. It actually 00:20:58.269 --> 00:21:00.410 provides clinical data on a highly effective 00:21:00.410 --> 00:21:03.400 intervention. Yes. The clinical data shows that 00:21:03.400 --> 00:21:05.960 the presence of continuous labor support, specifically 00:21:05.960 --> 00:21:08.279 from someone like a DOA and the implementation 00:21:08.279 --> 00:21:11.339 of culturally respectful care, actively change 00:21:11.339 --> 00:21:13.720 physical outcomes. It changes the actual numbers. 00:21:13.980 --> 00:21:15.859 The data proves it shortens the length of labor, 00:21:16.359 --> 00:21:18.200 decreases the need for operative interventions, 00:21:18.740 --> 00:21:20.960 and materially reduces maternal morbidity and 00:21:20.960 --> 00:21:23.460 mortality, especially for historically marginalized 00:21:23.460 --> 00:21:26.579 groups. It's a profound realization for a clinician. 00:21:26.910 --> 00:21:29.609 You can have all the pathophysiology perfectly 00:21:29.609 --> 00:21:32.569 memorized. You can know exactly how to massage 00:21:32.569 --> 00:21:35.410 a boggy uterus or calculate quantitative blood 00:21:35.410 --> 00:21:37.930 loss. But the research is telling us that human 00:21:37.930 --> 00:21:40.589 connection, dedicated advocacy, and cultural 00:21:40.589 --> 00:21:44.029 respect are literal, evidence -based interventions. 00:21:44.250 --> 00:21:46.190 They're life -saving tools. How you listen to 00:21:46.190 --> 00:21:48.569 your patient and how you advocate for their pain 00:21:48.569 --> 00:21:51.029 is just as essential to their physical safety 00:21:51.029 --> 00:21:54.529 as the oxytocin hanging on the IV pole. It brings 00:21:54.529 --> 00:21:56.980 us right back to where we started. You are stepping 00:21:56.980 --> 00:21:59.380 out of the clean, binary world of the x -ray 00:21:59.380 --> 00:22:01.940 machine. You are entering a dynamic space where 00:22:01.940 --> 00:22:04.259 your clinical knowledge and your human empathy 00:22:04.259 --> 00:22:06.440 have to work together to guide two patients safely 00:22:06.440 --> 00:22:08.839 through the doorway. Thank you for joining us 00:22:08.839 --> 00:22:10.960 on this deep dive. Keep those memory anchors 00:22:10.960 --> 00:22:12.980 close, trust your assessments, and we'll catch 00:22:12.980 --> 00:22:13.599 you on the next one.
