WEBVTT 00:00:06.059 --> 00:00:09.800 Welcome to the bed. We'll go ahead and give you 00:00:09.800 --> 00:00:12.580 the story. This is all going to happen super 00:00:12.580 --> 00:00:46.729 fast. Welcome to the emergency room. Welcome 00:00:46.729 --> 00:00:50.850 back to the deep dive. Today we are wading into 00:00:50.850 --> 00:00:55.460 what I think is probably the murkiest highest 00:00:55.460 --> 00:00:57.759 stakes territory in all of pediatric health care. 00:00:57.780 --> 00:00:59.759 Oh, for sure. We are talking about infection. 00:01:00.500 --> 00:01:02.780 And I know the moment I say infection control, 00:01:03.000 --> 00:01:05.000 half the audience probably glosses over and thinks 00:01:05.000 --> 00:01:08.099 about, you know, hand sanitizer and generic posters 00:01:08.099 --> 00:01:10.620 in the break room. Right. It feels like the boring 00:01:10.620 --> 00:01:12.500 stuff, the stuff you have to memorize just to 00:01:12.500 --> 00:01:14.959 pass a safety quiz. Exactly. It has this reputation 00:01:14.959 --> 00:01:17.219 for being dry. It absolutely does. It gets a 00:01:17.219 --> 00:01:19.980 bad rap as being like compliance work. But when 00:01:19.980 --> 00:01:21.799 you actually get onto the floor, you're sitting 00:01:21.799 --> 00:01:25.060 for your boards, infection is. It's the beast. 00:01:25.260 --> 00:01:26.879 It is the beast. And when I was going through 00:01:26.879 --> 00:01:28.739 the materials for today, specifically chapter 00:01:28.739 --> 00:01:31.000 15 of the pediatric nursing education materials, 00:01:31.459 --> 00:01:34.060 plus all those dense slides on disease processes, 00:01:34.620 --> 00:01:37.560 I realized that in pediatrics, infection isn't 00:01:37.560 --> 00:01:40.579 just about hygiene. Not at all. It's essentially 00:01:40.579 --> 00:01:43.159 high -stakes detective work, where the victim, 00:01:43.280 --> 00:01:45.500 the patient, Often can't even tell you what's 00:01:45.500 --> 00:01:48.200 wrong. That is the perfect way to frame it. If 00:01:48.200 --> 00:01:50.700 you are an adult and you get an infection, your 00:01:50.700 --> 00:01:53.599 body has a mature, fortified defense system. 00:01:53.980 --> 00:01:56.579 You get a fever, you feel crummy, you take some 00:01:56.579 --> 00:01:58.939 ibuprofen, you sleep it off. Right, you can handle 00:01:58.939 --> 00:02:02.060 it. You can handle it. In pediatrics, particularly 00:02:02.060 --> 00:02:04.359 with the really little ones, the immune system 00:02:04.359 --> 00:02:07.390 is basically a construction site. The walls aren't 00:02:07.390 --> 00:02:09.550 up, the roof isn't finished, and the security 00:02:09.550 --> 00:02:12.550 guards haven't been hired yet. So an infection 00:02:12.550 --> 00:02:15.129 isn't an annoyance, it's a physiological crisis. 00:02:15.590 --> 00:02:18.250 And the margin for error is razor thin. Tiny, 00:02:18.550 --> 00:02:22.030 absolutely tiny. A missed cue in a 30 -year -old 00:02:22.030 --> 00:02:24.530 means they are sick for an extra day. A missed 00:02:24.530 --> 00:02:27.090 cue in a three -week -old, that can be catastrophic 00:02:27.090 --> 00:02:29.009 in a matter of hours. That's the gravity we're 00:02:29.009 --> 00:02:30.990 dealing with. Now, looking at this stack of source 00:02:30.990 --> 00:02:33.789 material, it is massive. I mean, we have everything 00:02:33.789 --> 00:02:35.949 from the microscopic pathophysiology of sepsis 00:02:35.849 --> 00:02:38.449 to the macro -social issues of lice and STIs. 00:02:39.129 --> 00:02:41.729 We have charts on rashes, protocols for ticks, 00:02:42.169 --> 00:02:44.949 and isolation tiers. It's overwhelming. It is. 00:02:45.050 --> 00:02:47.270 And that's why students panic. They try to memorize 00:02:47.270 --> 00:02:50.409 every single bug, every incubation period, every 00:02:50.409 --> 00:02:53.770 specific antibiotic dose. You can't do that. 00:02:54.030 --> 00:02:56.669 You'll burn out. It's impossible. So our mission 00:02:56.669 --> 00:03:00.750 today is to do what we always do, apply the Pareto 00:03:00.750 --> 00:03:03.610 principle. We are going to hunt for the 80 -20. 00:03:03.789 --> 00:03:06.629 Yes. We want the 20 % of the insights that are 00:03:06.629 --> 00:03:09.669 going to help you answer 80 % of the exam questions. 00:03:10.150 --> 00:03:13.050 And more importantly, keep 100 % of your patients 00:03:13.050 --> 00:03:15.969 safe. Exactly. We aren't just reading the textbook. 00:03:16.189 --> 00:03:19.370 We are trying to decode the mind map of the safety 00:03:19.370 --> 00:03:22.030 experts and the exam writers. We want to spot 00:03:22.030 --> 00:03:24.550 the traps before you step in them. Let's jump 00:03:24.550 --> 00:03:26.669 right in then. Before we get to the specific 00:03:26.669 --> 00:03:30.129 bugs, you know the measles and the MRSA, we need 00:03:30.129 --> 00:03:32.449 to talk about the master map. These are the meta 00:03:32.449 --> 00:03:34.569 -patterns you identified in the reading that 00:03:34.569 --> 00:03:36.830 seem to apply across the board. Yes, these are 00:03:36.830 --> 00:03:38.949 the big picture rules. The first one, and honestly 00:03:38.949 --> 00:03:41.490 the most stressful one for new nurses and parents 00:03:41.490 --> 00:03:44.469 alike, is what I'm calling the fever fear. Oh 00:03:44.469 --> 00:03:47.789 yes, fever phobia is real. Parents are terrified 00:03:47.789 --> 00:03:49.750 of it, but nurses need to view it clinically 00:03:49.750 --> 00:03:52.840 with a very specific set of rules. And the text 00:03:52.840 --> 00:03:55.360 spends a lot of time on this. It seems like the 00:03:55.360 --> 00:03:57.539 biggest decision point regarding fever isn't 00:03:57.539 --> 00:04:00.759 how high is it, but how old is the kid? Precisely. 00:04:01.219 --> 00:04:03.960 Context is everything. If you take one single 00:04:03.960 --> 00:04:06.419 thing away from this entire deep dive today, 00:04:06.580 --> 00:04:09.340 let it be this. The neonate rule. This is your 00:04:09.340 --> 00:04:11.319 can't miss scenario. OK, walk us through it. 00:04:11.360 --> 00:04:14.439 We are talking about infants younger than three 00:04:14.439 --> 00:04:17.420 months. And really, younger than 28 days is the 00:04:17.420 --> 00:04:20.300 hypercritical zone. But the exam standard is 00:04:20.300 --> 00:04:22.839 usually that under three month window. OK, under 00:04:22.839 --> 00:04:25.000 three months. If you have an infant in this age 00:04:25.000 --> 00:04:27.040 group with a rectal temperature greater than 00:04:27.040 --> 00:04:30.399 38 degrees Celsius, that's 100 .4 degrees Fahrenheit, 00:04:30.899 --> 00:04:33.600 you stop everything. Red alert. Full red alert. 00:04:33.759 --> 00:04:35.759 This is not give them some Tylenol and see if 00:04:35.759 --> 00:04:38.620 it goes down. This is an automatic septic workup. 00:04:38.829 --> 00:04:41.610 Period. Why is that line in the sand so rigid 00:04:41.610 --> 00:04:43.829 for them? Why can't we just wait and see with 00:04:43.829 --> 00:04:46.490 a baby that young? Because they cannot localize 00:04:46.490 --> 00:04:49.610 infection. If you or I get a cut on our finger 00:04:49.610 --> 00:04:52.269 and bacteria get in, our immune system rushes 00:04:52.269 --> 00:04:55.110 to that specific spot. It builds a wall. It gets 00:04:55.110 --> 00:04:57.610 red and puffy right there. Exactly. It gets red, 00:04:57.769 --> 00:05:00.430 puffy, and swollen right there. We wall it off. 00:05:01.029 --> 00:05:05.079 That's a mature response. A neonate. They don't 00:05:05.079 --> 00:05:07.639 have that capability. Their immune system is, 00:05:07.639 --> 00:05:10.339 well, it's immature. They don't have the opsonization 00:05:10.339 --> 00:05:12.879 ability, which is basically tagging the bad guys 00:05:12.879 --> 00:05:15.019 for destruction perfected yet. So the bacteria 00:05:15.019 --> 00:05:17.100 doesn't get contained. It doesn't. It enters. 00:05:17.240 --> 00:05:19.519 And instead of staying in the finger or the ear, 00:05:19.600 --> 00:05:22.240 it goes systemic. It jumps right into the bloodstream. 00:05:22.319 --> 00:05:25.139 So it goes from a local issue to sepsis blood 00:05:25.139 --> 00:05:27.560 poisoning lightning fast. Lightning fast. And 00:05:27.560 --> 00:05:29.620 because they have maternal antibodies fading 00:05:29.620 --> 00:05:32.040 and their own antibodies not yet built, They 00:05:32.040 --> 00:05:35.399 are basically defenseless. So a fever in a neonate 00:05:35.399 --> 00:05:37.839 is subsys until proven otherwise. And that brings 00:05:37.839 --> 00:05:40.399 us to the exam trap I saw in the notes. The classic 00:05:40.399 --> 00:05:43.160 distractor answer. The helpful nurse trap. I 00:05:43.160 --> 00:05:45.639 love that name for it. The question will describe 00:05:45.639 --> 00:05:50.060 a 60 gold with a fever of 100 .5. And one of 00:05:50.060 --> 00:05:52.939 the answers, it will sound so reasonable, will 00:05:52.939 --> 00:05:56.620 be administer acetaminophen and reassess in four 00:05:56.620 --> 00:05:58.660 hours. Which sounds like a very reasonable thing 00:05:58.660 --> 00:06:01.500 to do. Of course you want to make the baby comfortable. 00:06:01.759 --> 00:06:04.579 It sounds compassionate, but it's dangerously 00:06:04.579 --> 00:06:07.759 wrong. If you give that Tylenol, you are masking 00:06:07.759 --> 00:06:10.000 the only sign of danger that baby is giving you. 00:06:10.079 --> 00:06:11.839 You're hiding the evidence. You're hiding the 00:06:11.839 --> 00:06:14.240 evidence. You never mask a fever in a neonate 00:06:14.240 --> 00:06:16.860 before full medical evaluation and cultures are 00:06:16.860 --> 00:06:19.560 drawn. You need to know why they are hot before 00:06:19.560 --> 00:06:21.500 you cool them down. It's a crucial distinction. 00:06:21.560 --> 00:06:24.160 OK. So moving to the second pattern on our master 00:06:24.160 --> 00:06:27.839 map. Isolation precautions. This always feels 00:06:27.839 --> 00:06:29.839 like a memory game. It does. You're walking down 00:06:29.839 --> 00:06:31.920 the hospital hallway, you see a color -coded 00:06:31.920 --> 00:06:34.220 sign on the door, and you have to know what gear 00:06:34.220 --> 00:06:37.540 to put on. The door sign game. Yeah. And it feels 00:06:37.540 --> 00:06:39.980 like pure memorization, but there is physics 00:06:39.980 --> 00:06:41.540 behind it. If you understand the physics, you 00:06:41.540 --> 00:06:43.579 don't have to memorize as much. The physics of 00:06:43.579 --> 00:06:46.379 the snot. Essentially, yes. The physics of the 00:06:46.379 --> 00:06:48.730 particle size. So the source material breaks 00:06:48.730 --> 00:06:51.430 this down into tier one and tier two. Tier one 00:06:51.430 --> 00:06:53.230 is standard precautions. And that's just being 00:06:53.230 --> 00:06:55.389 a decent human being. Right. Pretty much. Hand 00:06:55.389 --> 00:06:57.930 hygiene. Right. Hand hygiene, gloves if you're 00:06:57.930 --> 00:07:00.410 touching body fluids. This applies to every single 00:07:00.410 --> 00:07:04.209 patient, every single time. And the text hammers 00:07:04.209 --> 00:07:07.410 this home. Hand hygiene is the number one way 00:07:07.410 --> 00:07:10.350 to prevent the spread of infection. Period. It 00:07:10.350 --> 00:07:12.470 sounds cliche, but it's true. It's the cornerstone 00:07:12.470 --> 00:07:15.959 of safety. But the exams, they really focus on 00:07:15.959 --> 00:07:18.939 tier two, transmission -based precautions. Right, 00:07:19.360 --> 00:07:22.220 contact, droplet, and airborne. Help us sort 00:07:22.220 --> 00:07:24.459 these mentally. Okay, let's start with the icky 00:07:24.459 --> 00:07:27.300 stuff. Contact precautions. A very scientific 00:07:27.300 --> 00:07:29.839 term. Very. Think about things that live on the 00:07:29.839 --> 00:07:34.720 skin or in the gut. MRSA, C. diff, scabies, lice, 00:07:34.959 --> 00:07:38.120 RSV. These are transmitted by direct touch or 00:07:38.120 --> 00:07:40.399 by touching a surface the patient touched. So 00:07:40.399 --> 00:07:42.759 if it's sticky, icky, or crawling? It's contact. 00:07:42.800 --> 00:07:45.660 You need a gown and gloves. And here is a huge 00:07:45.660 --> 00:07:49.600 nuance for C. Difclostridium difficile hand sanitizer 00:07:49.600 --> 00:07:51.600 does not kill the spores. Oh, that's a big one. 00:07:51.899 --> 00:07:53.939 Huge. You physically have to wash your hands 00:07:53.939 --> 00:07:56.100 with soap and water to rinse them down the drain. 00:07:56.379 --> 00:07:58.899 That is a frequent, frequent exam question. Okay, 00:07:58.920 --> 00:08:01.819 good to know. Now the confusing pair, droplet 00:08:01.819 --> 00:08:04.040 versus airborne, both come out of the lungs. 00:08:04.300 --> 00:08:06.540 How do I tell them apart? Think about gravity. 00:08:07.100 --> 00:08:10.740 OK. Droplets are heavy. They are like wet confetti. 00:08:11.439 --> 00:08:15.519 If I sneeze and I have the flu or pertussis or 00:08:15.519 --> 00:08:18.579 meningitis, those particles fly out, travel about 00:08:18.579 --> 00:08:21.339 three feet, and then gravity pulls them to the 00:08:21.339 --> 00:08:23.800 floor. So the blast zone is three feet. Correct. 00:08:24.060 --> 00:08:27.019 So for droplet precautions, you just need a standard 00:08:27.019 --> 00:08:29.579 surgical mask if you are within that three foot 00:08:29.579 --> 00:08:31.980 radius. You protect your mucous membranes from 00:08:31.980 --> 00:08:34.480 the confetti. Got it. And airborne. Airborne 00:08:34.480 --> 00:08:36.779 particles are tiny. They're like smoke. They 00:08:36.779 --> 00:08:38.779 don't fall. They float on air currents. They 00:08:38.779 --> 00:08:41.240 can drift out into the hallway. That's terrifying. 00:08:41.340 --> 00:08:43.600 It is. That's why the list for airborne is short 00:08:43.600 --> 00:08:47.240 and very scary. Measles, varicella, which is 00:08:47.240 --> 00:08:51.500 chickenpox, and tuberculosis or TB. And since 00:08:51.500 --> 00:08:54.200 it floods like smoke, a regular mask isn't enough. 00:08:54.379 --> 00:08:57.700 It leaks. You need an N95 respirator that is 00:08:57.700 --> 00:09:00.960 fitted to your face to filter the air. And you 00:09:00.960 --> 00:09:03.700 need a negative pressure room. Right. Explain 00:09:03.700 --> 00:09:05.240 the negative pressure room for those who haven't 00:09:05.240 --> 00:09:07.500 seen one. What's that actually doing? So it's 00:09:07.500 --> 00:09:09.620 a room where the ventilation system is engineered 00:09:09.620 --> 00:09:12.000 to suck air in from the hallway and then vent 00:09:12.000 --> 00:09:14.179 it out through a HEPA filter to the outside. 00:09:14.500 --> 00:09:17.120 It prevents the smoke from drifting out into 00:09:17.120 --> 00:09:20.100 the corridor when you open the door. OK. So heavy 00:09:20.100 --> 00:09:22.679 confetti equals droplet equals a regular mass. 00:09:23.059 --> 00:09:27.379 Floating smoke equals airborne equals N95 plus 00:09:27.379 --> 00:09:30.019 a negative pressure room. You got it. That's 00:09:30.019 --> 00:09:32.139 the physics. Perfect. Let's hit the third pattern 00:09:32.139 --> 00:09:34.639 on our map. I call this the treat the whole house 00:09:34.639 --> 00:09:36.940 rule. This seems to pop up mostly with the parasites. 00:09:37.340 --> 00:09:40.159 Yes. This is a concept of environment as patient 00:09:40.159 --> 00:09:43.340 with things like scabies, pinworms, or lice. 00:09:43.600 --> 00:09:46.039 If you just treat the child, you will fail. Because 00:09:46.039 --> 00:09:48.379 the bugs are on the couch. On the couch, on the 00:09:48.379 --> 00:09:50.620 sheets, in the stuffed animals, and on the siblings. 00:09:51.409 --> 00:09:54.269 If you treat the child for scabies, but the asymptomatic 00:09:54.269 --> 00:09:56.629 mom is carrying a mite, or you don't wash the 00:09:56.629 --> 00:09:59.070 sheets in hot water, the infection just pings 00:09:59.070 --> 00:10:01.590 back and forth. It's the definition of insanity. 00:10:01.669 --> 00:10:03.450 It really is. You're just chasing your tail. 00:10:03.570 --> 00:10:06.009 So if an exam question asks, the child keeps 00:10:06.009 --> 00:10:09.250 getting reinfected, what went wrong? I'm looking 00:10:09.250 --> 00:10:11.330 for the answer about the family or the laundry. 00:10:11.570 --> 00:10:14.330 Bingo. Treatment failure in parasites is almost 00:10:14.330 --> 00:10:16.830 always a failure to treat the contacts or the 00:10:16.830 --> 00:10:19.169 environment. It's a key educational point for 00:10:19.169 --> 00:10:21.250 parents. All right. That is a solid foundation. 00:10:21.370 --> 00:10:23.769 We have our fever rules, our isolation physics, 00:10:24.029 --> 00:10:26.769 and our environmental strategy. Now, I want to 00:10:26.769 --> 00:10:29.289 go deep into the specific systems. Let's do it. 00:10:29.490 --> 00:10:32.289 We are going to break this down by body system, 00:10:32.629 --> 00:10:35.210 starting with the most dangerous one, the absolute 00:10:35.210 --> 00:10:39.049 number one failure to rescue scenario, sepsis. 00:10:39.250 --> 00:10:42.110 Sepsis is the monster under the bed in pediatrics. 00:10:42.210 --> 00:10:44.850 It's a systemic over -response to an infection. 00:10:45.190 --> 00:10:48.250 The text mentions Sura's systemic inflammatory 00:10:48.250 --> 00:10:50.840 response syndrome. Can we translate that into 00:10:50.840 --> 00:10:53.840 plain English? What is actually happening inside 00:10:53.840 --> 00:10:56.840 the child's body when sepsis hits? Okay, so imagine 00:10:56.840 --> 00:10:59.299 the body is a house under attack by a burglar. 00:10:59.539 --> 00:11:02.440 That's the bacteria. The immune system pulls 00:11:02.440 --> 00:11:05.190 the fire alarm to summon help. Those are the 00:11:05.190 --> 00:11:08.070 cytokines. Okay, firearm is pulled. But in sepsis, 00:11:08.269 --> 00:11:10.950 the system malfunctions. Instead of just sending 00:11:10.950 --> 00:11:13.669 a police car to the front door, the body turns 00:11:13.669 --> 00:11:16.789 on every single fire hose in every single room 00:11:16.789 --> 00:11:19.330 at full blast. So you flood the house trying 00:11:19.330 --> 00:11:21.169 to get the burglar? You destroy the house to 00:11:21.169 --> 00:11:23.850 save it. The blood vessels react to this alarm 00:11:23.850 --> 00:11:26.309 by dilating, getting really wide. And when the 00:11:26.309 --> 00:11:28.389 pipes get wide, the pressure drops. Exactly. 00:11:28.549 --> 00:11:30.950 Blood pressure plummets. Simultaneously, the 00:11:30.950 --> 00:11:33.769 vessels become leaky. Fluid leaks out of the 00:11:33.769 --> 00:11:35.889 veins and into the tissue. Yeah. That's edema. 00:11:36.190 --> 00:11:37.909 So the pipes are too wide and you're losing water 00:11:37.909 --> 00:11:40.250 from the pipes. Right. So now you have no pressure 00:11:40.250 --> 00:11:42.950 to push blood to the vital organs, the kidneys, 00:11:43.370 --> 00:11:46.009 the brain, the gut. They start to starve for 00:11:46.009 --> 00:11:48.429 oxygen. And then come the clots. I saw that in 00:11:48.429 --> 00:11:51.120 the notes. Right. The body tries to fix the leaks 00:11:51.120 --> 00:11:54.019 by throwing clots everywhere, but these are microclots, 00:11:54.059 --> 00:11:56.200 and they get stuck in the tiny capillaries of 00:11:56.200 --> 00:11:59.019 the fingers, toes, and kidneys, further blocking 00:11:59.019 --> 00:12:02.279 blood flow. It is a cascade of disaster. Now, 00:12:02.519 --> 00:12:05.419 we talked about the fever rule in neonates, but 00:12:05.419 --> 00:12:07.620 the notes say that infants with sepsis don't 00:12:07.620 --> 00:12:10.340 always have a fever. This seems counterintuitive. 00:12:10.480 --> 00:12:12.940 This is the cold baby rule, and honestly, this 00:12:12.940 --> 00:12:15.399 is what keeps experienced ER nurses up at night. 00:12:15.620 --> 00:12:19.129 Why? Infants, especially preemies, have an immature 00:12:19.129 --> 00:12:21.769 hypothalamus. That's the body's thermostat. When 00:12:21.769 --> 00:12:23.970 they get overwhelmed by infection, the thermostat 00:12:23.970 --> 00:12:26.350 breaks. Instead of getting hot, they get cold. 00:12:26.750 --> 00:12:30.110 Hypothermia. Yes. A temperature below 36 .5 Celsius. 00:12:30.529 --> 00:12:32.629 If a parent brings in a baby and says he feels 00:12:32.629 --> 00:12:34.769 cold to the touch or he's just floppy and not 00:12:34.769 --> 00:12:37.750 eating, that is infinitely scarier to me than 00:12:37.750 --> 00:12:40.549 a screaming baby with a 103 fever. Really? A 00:12:40.549 --> 00:12:43.149 screaming baby has energy. A cold, floppy baby 00:12:43.149 --> 00:12:45.230 is shutting down. Their body can't even mount 00:12:45.230 --> 00:12:48.210 a a fever response. So clinically, what are we 00:12:48.210 --> 00:12:49.990 looking at? If I walk into the room, how do I 00:12:49.990 --> 00:12:52.230 spot this early? What are the first signs? You 00:12:52.230 --> 00:12:55.509 look at two things, mental status and perfusion. 00:12:56.049 --> 00:12:58.990 Mental status in a baby isn't can they do math. 00:12:59.230 --> 00:13:02.450 It's are they acting right? So their normal baseline. 00:13:02.649 --> 00:13:05.169 Exactly. Are they irritable in a way that's not 00:13:05.169 --> 00:13:08.309 normal? Are they lethargic? Is the cry weak and 00:13:08.309 --> 00:13:10.909 whimpering instead of strong? OK. And perfusion. 00:13:11.289 --> 00:13:13.870 It's blood flow. Check capillary refill on the 00:13:13.870 --> 00:13:15.929 sternum. Is it taking longer than two or three 00:13:15.929 --> 00:13:19.529 seconds to pink up? Look at the skin. Is it mottled? 00:13:19.750 --> 00:13:22.230 Mottled. That's that lacy purple -blue pattern 00:13:22.230 --> 00:13:24.629 on the skin, right? Yeah. That is the body clamping 00:13:24.629 --> 00:13:26.730 down, pulling blood away from the skin to try 00:13:26.730 --> 00:13:29.149 to save the heart and brain. It's a late, late 00:13:29.149 --> 00:13:32.029 warning sign. And check the extremities. Cool 00:13:32.029 --> 00:13:35.129 hands and feet. OK. So we suspect sepsis. The 00:13:35.129 --> 00:13:37.490 clock is ticking. The source material outlines 00:13:37.490 --> 00:13:39.990 the bundle. It sounds like a military operation. 00:13:40.429 --> 00:13:42.350 It is. It's a race against time, and the order 00:13:42.350 --> 00:13:45.029 is absolutely critical. What's step one? Step 00:13:45.029 --> 00:13:47.629 one. Cultures. You have to know what bug you 00:13:47.629 --> 00:13:50.070 are fighting. You need blood, urine, and ideally 00:13:50.070 --> 00:13:52.669 spinal fluid, the CSF, before you taint the scene 00:13:52.669 --> 00:13:55.590 with any drugs. Okay. Step two. Antibiotics. 00:13:55.909 --> 00:13:58.529 Immediately. You use a broad spectrum antibiotic. 00:13:58.669 --> 00:14:01.529 It's like a shotgun approach. Until you can identify 00:14:01.529 --> 00:14:03.889 the specific bug from the cultures. And there's 00:14:03.889 --> 00:14:06.309 a nuance there, right, about waiting. A crucial 00:14:06.309 --> 00:14:09.700 nuance. If you cannot get the IV access or the 00:14:09.700 --> 00:14:12.360 spinal tap quickly, you do not wait. You give 00:14:12.360 --> 00:14:14.899 the antibiotics. It's better to have a sterile 00:14:14.899 --> 00:14:17.419 culture and a live baby than a perfect culture 00:14:17.419 --> 00:14:20.580 and a dead baby. Draw than drug. But don't let 00:14:20.580 --> 00:14:22.980 the draw delay the drug for too long. Exactly. 00:14:23.320 --> 00:14:27.159 And step three, fill the tank. Fluids. You have 00:14:27.159 --> 00:14:30.200 those dilated, leaky vessels. You need to pour 00:14:30.200 --> 00:14:32.860 volume in isotonic fluids like normal saline 00:14:32.860 --> 00:14:35.379 to prop up the blood pressure. And you're watching 00:14:35.379 --> 00:14:38.340 out for septic shock. The notes say hypotension, 00:14:38.580 --> 00:14:41.120 low blood pressure is a late sign. This is the 00:14:41.120 --> 00:14:43.580 biggest trap in pediatrics. Kids have strong, 00:14:43.659 --> 00:14:45.539 healthy hearts. When they start to get sick, 00:14:45.679 --> 00:14:48.080 their heart rate goes up. Tachycardia. They pump 00:14:48.080 --> 00:14:50.720 faster and faster to compensate. So they can 00:14:50.720 --> 00:14:52.419 keep their blood pressure up for a while. For 00:14:52.419 --> 00:14:54.580 a very long time, while they are essentially 00:14:54.580 --> 00:14:57.440 dying inside, they compensate, compensate, compensate, 00:14:57.659 --> 00:14:59.559 and then they fall off a cliff. So if you wait 00:14:59.559 --> 00:15:01.720 for the blood pressure to drop, You have waited 00:15:01.720 --> 00:15:04.539 too long. They are about to crash. You treat 00:15:04.539 --> 00:15:07.399 the tachycardia and the poor perfusion. Do not 00:15:07.399 --> 00:15:09.539 trust the blood pressure cuff to tell you everything 00:15:09.539 --> 00:15:13.100 is OK. That is a chilling but vital lesson. Before 00:15:13.100 --> 00:15:14.879 we leave sepsis, let's touch on the developmental 00:15:14.879 --> 00:15:18.519 impact. If a baby survives this but spends two 00:15:18.519 --> 00:15:21.580 weeks in the ICU getting poked and prodded, what 00:15:21.580 --> 00:15:24.000 does that do to them long term? It disrupts everything. 00:15:24.250 --> 00:15:26.610 For an infant, development is about attachment 00:15:26.610 --> 00:15:30.370 and trust. Erickson's stage of trust versus mistrust. 00:15:30.669 --> 00:15:32.730 They need to know that when they cry, someone 00:15:32.730 --> 00:15:35.009 holds them, someone comforts them. But in the 00:15:35.009 --> 00:15:37.110 ICU, that's not always possible. Right. They 00:15:37.110 --> 00:15:40.309 are often sedated, intubated, and painful procedures 00:15:40.309 --> 00:15:43.710 happen constantly. They risk developing mistrust. 00:15:44.029 --> 00:15:46.409 They learn the world is a painful, scary place. 00:15:46.470 --> 00:15:48.450 So what can the nurse do to mitigate that? You 00:15:48.450 --> 00:15:50.429 have to involve the parents immediately. They're 00:15:50.429 --> 00:15:52.889 the anchor. Even if the baby is intubated, have 00:15:52.889 --> 00:15:55.169 the mom hold their hand, have the dad read a 00:15:55.169 --> 00:15:57.950 story, encourage kangaroo care, skin -to -skin 00:15:57.950 --> 00:16:01.090 contact, as soon as it's medically safe. You 00:16:01.090 --> 00:16:04.070 have to maintain that bond or you'll see developmental 00:16:04.070 --> 00:16:06.029 regression where the baby withdraws or stops 00:16:06.029 --> 00:16:08.250 interacting. Okay, that makes sense. Let's switch 00:16:08.250 --> 00:16:11.129 gears. We're moving from the invisible internal 00:16:11.129 --> 00:16:14.429 threat to the very visible external one, bacterial 00:16:14.429 --> 00:16:17.070 skin infections. Okay. The sources highlight 00:16:17.070 --> 00:16:20.330 two big players here, MRSA and scarlet fever. 00:16:20.480 --> 00:16:24.360 Let's start with MRSA. Specifically, CAMRSA, 00:16:24.580 --> 00:16:27.159 community -acquired, methicillin -resistant Staph 00:16:27.159 --> 00:16:29.620 aureus. That is a mouthful. It's a nasty bug. 00:16:30.059 --> 00:16:32.340 And the classic history, the story you'll hear 00:16:32.340 --> 00:16:34.840 from parents, almost always involves a spider. 00:16:35.019 --> 00:16:37.700 A spider. Almost every parent of a kid with MRSA 00:16:37.700 --> 00:16:40.299 comes in saying, I think a spider bit him. Why 00:16:40.299 --> 00:16:43.600 is that? Because it starts as a red, raised bump 00:16:43.600 --> 00:16:46.539 that is really painful. It looks just like a 00:16:46.539 --> 00:16:48.759 bug bite. But unless you saw the spider with 00:16:48.759 --> 00:16:51.600 a name tag, it's probably MRSA. What's the key 00:16:51.600 --> 00:16:54.279 difference? MRSA progresses rapidly to become 00:16:54.279 --> 00:16:56.919 purulent, filled with pus, and sometimes necrotic. 00:16:57.480 --> 00:17:00.159 It forms a hard, painful abscess. A spider bite 00:17:00.159 --> 00:17:02.059 usually doesn't do that. The antibiotics alone 00:17:02.059 --> 00:17:03.919 don't work. You can't just give a pill for it. 00:17:04.079 --> 00:17:06.559 Not usually, no. The need to know intervention 00:17:06.559 --> 00:17:09.700 is eye and de -incision and drainage. You have 00:17:09.700 --> 00:17:12.440 to lance the boil and get the pus out. It's gross, 00:17:12.539 --> 00:17:15.299 but it's the only way to clear the massive infection 00:17:15.299 --> 00:17:18.099 load. Then you follow up with specific antibiotics 00:17:18.099 --> 00:17:21.759 like clindamycin or Bactrim because regular amoxicillin 00:17:21.759 --> 00:17:24.420 won't touch it. And prevention. This seems to 00:17:24.420 --> 00:17:27.599 be a big deal in sports. Huge in wrestling, football, 00:17:28.160 --> 00:17:30.259 gymnastics, anything with mats and sweat. The 00:17:30.259 --> 00:17:32.640 bacteria can live on the equipment. The education 00:17:32.640 --> 00:17:35.240 is simple. Don't share towels, don't share razors, 00:17:35.279 --> 00:17:37.839 and shower immediately after practice. Keep any 00:17:37.839 --> 00:17:40.759 cuts covered. Okay, now scarlet fever. This sounds 00:17:40.759 --> 00:17:42.819 like something out of a Dickens novel. Little 00:17:42.819 --> 00:17:44.980 Timmy has scarlet fever. Right, but it never 00:17:44.980 --> 00:17:48.039 left. It's caused by group A strep, the exact 00:17:48.039 --> 00:17:50.259 same bug that causes strep throat. So it's just 00:17:50.259 --> 00:17:52.420 strep throat. It's strep throat, but this particular 00:17:52.420 --> 00:17:55.599 strain has a superpower. It releases a toxin. 00:17:55.869 --> 00:17:58.650 and that toxin is what causes the characteristic 00:17:58.650 --> 00:18:01.329 signs. And the toxin causes the rash. Yes, and 00:18:01.329 --> 00:18:03.410 you need to memorize the description of this 00:18:03.410 --> 00:18:05.890 rash because it is unique. It is described as 00:18:05.890 --> 00:18:08.690 sandpaper. If you run your hand over the child's 00:18:08.690 --> 00:18:10.809 trunk, it feels rough. It looks like a sunburn 00:18:10.809 --> 00:18:13.650 with goosebumps. It starts on the chest and spreads, 00:18:13.710 --> 00:18:17.190 but, and here is the key identifier, it spares 00:18:17.190 --> 00:18:19.710 the area around the mouth. So they have this 00:18:19.710 --> 00:18:21.930 pale ring around their mouth. It's called circumoral 00:18:21.930 --> 00:18:25.029 pallor and a bright red face. And the tongue. 00:18:25.210 --> 00:18:27.289 I remember reading about that. The strawberry 00:18:27.289 --> 00:18:30.309 tongue. It's a two -stage process. First, it 00:18:30.309 --> 00:18:32.950 has a white coating. Then that coating peels 00:18:32.950 --> 00:18:35.910 off and the tongue looks beefy, red, and bumpy, 00:18:36.150 --> 00:18:38.210 just like a strawberry. Why do we care so much 00:18:38.210 --> 00:18:41.109 about this? Is it just a rash? The rash isn't 00:18:41.109 --> 00:18:43.789 the problem. The so -what is the complications. 00:18:44.369 --> 00:18:47.029 If you don't treat group A strep properly, the 00:18:47.029 --> 00:18:49.210 toxin triggers an autoimmune response that can 00:18:49.210 --> 00:18:51.470 attack the heart valves causing rheumatic fever 00:18:51.470 --> 00:18:53.890 or the kidneys causing glomerulonephritis. So 00:18:53.890 --> 00:18:55.829 we aren't treating the sore throat. We are treating 00:18:55.829 --> 00:18:58.369 to save the heart valves down the line. Exactly. 00:18:58.710 --> 00:19:02.230 That's why it's 10 days of penicillin or amoxicillin, 00:19:02.329 --> 00:19:05.089 non -negotiable. And a really practical tip from 00:19:05.089 --> 00:19:07.569 the notes. Throw away the toothbrush. After 24 00:19:07.569 --> 00:19:10.740 hours of antibiotics. Yes. If you keep using 00:19:10.740 --> 00:19:12.960 the old toothbrush, you are just re -inoculating 00:19:12.960 --> 00:19:14.960 yourself with the bacteria every single morning. 00:19:15.119 --> 00:19:17.740 That's a great tip. Okay, let's move to the respiratory 00:19:17.740 --> 00:19:19.920 system. We have two villains here, Pertussis 00:19:19.920 --> 00:19:22.900 and Diphtheria. Both are vaccine preventable, 00:19:23.099 --> 00:19:26.640 but both are making comebacks. Sadly true. Let's 00:19:26.640 --> 00:19:29.380 start with Pertussis, or whooping cough. I think 00:19:29.380 --> 00:19:32.039 everyone has heard that sound on YouTube. That 00:19:32.039 --> 00:19:34.660 terrible coughing fit followed by a high pitch 00:19:34.660 --> 00:19:38.180 whoop as they gasp for air. It's awful. It is 00:19:38.180 --> 00:19:40.279 awful. And that's the classic presentation in 00:19:40.279 --> 00:19:43.119 an older child. But the source material has a 00:19:43.119 --> 00:19:45.680 massive red flag for infants under six months. 00:19:45.900 --> 00:19:48.480 The silent pertussis. Right. Babies don't have 00:19:48.480 --> 00:19:50.799 the chest wall strength or the lung capacity 00:19:50.799 --> 00:19:53.200 to make that whoop sound. They cough and cough 00:19:53.200 --> 00:19:55.140 and cough and then nothing. They stop breathing. 00:19:55.220 --> 00:19:58.019 They go apneic. That is terrifying. So a parent 00:19:58.019 --> 00:20:00.160 brings a three month old in because he stops 00:20:00.160 --> 00:20:02.400 breathing sometimes. You have to think pertussis. 00:20:02.500 --> 00:20:05.640 The bacteria Bordetella pertussis paralyzes the 00:20:05.640 --> 00:20:08.099 cilia, those little hair. in the lungs that sweep 00:20:08.099 --> 00:20:11.079 out mucus. So the baby literally drowns in their 00:20:11.079 --> 00:20:13.180 own secretions unless they can cause it out. 00:20:13.519 --> 00:20:15.940 So what's the treatment? Macrolide isosibiricin 00:20:15.940 --> 00:20:18.819 is common and droplet precautions immediately. 00:20:19.539 --> 00:20:21.900 And going back to our master pattern, you treat 00:20:21.900 --> 00:20:25.119 the whole house. If the baby has it, mom and 00:20:25.119 --> 00:20:27.579 dad and the siblings are likely carriers, even 00:20:27.579 --> 00:20:30.579 if they just have a mild cough. Everyone gets 00:20:30.579 --> 00:20:32.819 antibiotics. Let's talk about the developmental 00:20:32.819 --> 00:20:35.960 impact of Pertosis, especially in infants. The 00:20:35.960 --> 00:20:39.319 biggest impact is feeding and growth. If a baby 00:20:39.319 --> 00:20:41.500 is coughing until they vomit, which is really 00:20:41.500 --> 00:20:44.119 common, it's called post -tussive emesis, and 00:20:44.119 --> 00:20:46.279 they're struggling to breathe, they can't eat. 00:20:46.519 --> 00:20:48.519 They're using all their energy just to breathe. 00:20:48.640 --> 00:20:51.170 All of it. They burn massive calories fighting 00:20:51.170 --> 00:20:53.970 to breathe, but take in zero calories. Failure 00:20:53.970 --> 00:20:56.670 to thrive is a real significant risk. The nurse 00:20:56.670 --> 00:20:59.470 has to monitor weight daily, and often you need 00:20:59.470 --> 00:21:02.289 to offer small, frequent feeds. Sometimes they 00:21:02.289 --> 00:21:04.289 even need an NG tube to keep their nutrition 00:21:04.289 --> 00:21:07.750 up while they recover. OK, now diphtheria. The 00:21:07.750 --> 00:21:10.339 notes call this the bull neck. This one is very 00:21:10.339 --> 00:21:12.839 rare in places with good vaccination, but it's 00:21:12.839 --> 00:21:15.740 deadly. It causes a thick gray coating to grow 00:21:15.740 --> 00:21:17.960 over the tonsils and the back of the throat. 00:21:18.220 --> 00:21:20.619 It looks like a membrane. A pseudomembrane. Yes. 00:21:21.059 --> 00:21:23.819 And the exam warning is in all caps in every 00:21:23.819 --> 00:21:28.279 textbook. Do not scrape IT. Why? If it's blocking 00:21:28.279 --> 00:21:30.259 the airway, shouldn't we try to remove it? If 00:21:30.259 --> 00:21:33.299 you try to scrape it, it bleeds profusely. And 00:21:33.299 --> 00:21:35.819 the trauma and swelling from trying can cause 00:21:35.819 --> 00:21:37.980 the airway to shut completely and immediately. 00:21:38.380 --> 00:21:40.779 It's better to leave it and treat with antitoxin 00:21:40.779 --> 00:21:43.380 and antibiotics and secure the airway if needed. 00:21:43.660 --> 00:21:46.160 Why is it called bull neck? Because the lymph 00:21:46.160 --> 00:21:48.740 nodes and the soft tissue in the neck swell outward 00:21:48.740 --> 00:21:51.180 so much that the neck can become as wide as the 00:21:51.180 --> 00:21:53.380 head. It looks like a bull's neck. It's a sign 00:21:53.380 --> 00:21:56.609 of severe airway compromise. Wow. Okay, let's 00:21:56.609 --> 00:21:59.049 slide into the neurological and toxin -mediated 00:21:59.049 --> 00:22:02.279 diseases. Tetanus and botulism. They feel like 00:22:02.279 --> 00:22:04.039 opposites of the same coin. They really are. 00:22:04.160 --> 00:22:06.819 Both are from Clostridium bacteria. Both involve 00:22:06.819 --> 00:22:09.460 potent neurotoxins affecting muscles. But you're 00:22:09.460 --> 00:22:11.240 right, they're opposites. Tetanus makes you tight, 00:22:11.359 --> 00:22:13.799 and botulism makes you loose. Tetanus is lockjaw. 00:22:13.980 --> 00:22:16.880 It's rigid paralysis. The bacteria enters through 00:22:16.880 --> 00:22:19.619 a dirty wound. A rusty nail is the classic, but 00:22:19.619 --> 00:22:22.299 any soil in a deep cut can do it. The toxin travels 00:22:22.299 --> 00:22:24.880 to the spinal cord and causes the muscles to 00:22:24.880 --> 00:22:27.700 contract and not let go. The image in the text 00:22:27.700 --> 00:22:31.809 shows a child in opus tutnos. It's a really dramatic 00:22:31.809 --> 00:22:33.869 picture. It is. That's where the back muscles 00:22:33.869 --> 00:22:36.309 contract so hard the child arches backward like 00:22:36.309 --> 00:22:38.650 a bow with only their head and heels touching 00:22:38.650 --> 00:22:41.630 the bed. It is incredibly painful and the spasms 00:22:41.630 --> 00:22:43.809 can be strong enough to actually break their 00:22:43.809 --> 00:22:46.450 own vertebrae. My god. So what is the nursing 00:22:46.450 --> 00:22:49.890 management aside from the anti -toxin and muscle 00:22:49.890 --> 00:22:52.130 relaxants? It's all about environment management. 00:22:52.609 --> 00:22:55.059 These spasms are triggered by stimulation. A 00:22:55.059 --> 00:22:57.740 loud noise, a bright light, a sudden touch can 00:22:57.740 --> 00:23:00.200 set off a full -body seizure -like spasm. So 00:23:00.200 --> 00:23:01.880 you basically put them in a sensory deprivation 00:23:01.880 --> 00:23:04.220 tank. That's a great way to think about it. Dark 00:23:04.220 --> 00:23:07.940 room, shades drawn, cluster your pair, whisper. 00:23:08.500 --> 00:23:10.440 Minimize handling. You want to keep that nervous 00:23:10.440 --> 00:23:13.000 system as absolutely calm as possible while the 00:23:13.000 --> 00:23:15.160 immunoglobulin and medications work. Now flip 00:23:15.160 --> 00:23:18.140 the coin. Botulism. The floppy baby disease. 00:23:18.440 --> 00:23:20.759 This toxin works at the neuromuscular junction. 00:23:21.119 --> 00:23:23.240 It blocks the signal from the nerve to the muscle, 00:23:23.359 --> 00:23:25.720 so the muscle never gets the memo to move. It's 00:23:25.720 --> 00:23:29.579 a descending paralysis. And the source is honey, 00:23:30.359 --> 00:23:33.339 for infants. For infants, yes. The spores of 00:23:33.339 --> 00:23:35.599 Clostridium botulinum can be found in honey. 00:23:36.240 --> 00:23:38.339 An adult's stomach is acidic enough to kill the 00:23:38.339 --> 00:23:41.539 spores, but an infant's stomach is not. So the 00:23:41.539 --> 00:23:43.759 spores can germinate in their gut and release 00:23:43.759 --> 00:23:46.700 the toxin. That's why we say no honey before 00:23:46.700 --> 00:23:49.059 age one. Strictly. It's a non -negotiable rule. 00:23:49.319 --> 00:23:51.400 So what does a botulism baby look like? What 00:23:51.400 --> 00:23:54.119 are the first signs? The very first sign is often 00:23:54.119 --> 00:23:57.460 constipation. The gut motility slows way down. 00:23:57.599 --> 00:24:00.299 Then they get weak. You'll see poor feeding because 00:24:00.299 --> 00:24:03.220 they can't suck effectively. A weak, whimpering 00:24:03.220 --> 00:24:06.059 cry. Loss of head control. They just feel like 00:24:06.059 --> 00:24:08.240 a ragdoll when you pick them up. And if it progresses? 00:24:08.519 --> 00:24:11.000 It hits the diaphragm. They stop breathing. They 00:24:11.000 --> 00:24:13.779 need a ventilator and a specific antidote called 00:24:13.779 --> 00:24:17.079 Baby Big, which is botulism immune globulin. 00:24:17.440 --> 00:24:19.980 Recovery is long. It can take weeks for those 00:24:19.980 --> 00:24:22.519 nerve endings to regrow and heal. What is the 00:24:22.519 --> 00:24:24.430 developmental fallout here? Well, think about 00:24:24.430 --> 00:24:27.190 a baby who can't move for weeks. They lose muscle 00:24:27.190 --> 00:24:29.109 tone. They can't practice lifting their head, 00:24:29.170 --> 00:24:31.849 rolling over, or grasping toys. All those critical 00:24:31.849 --> 00:24:34.809 milestones. Exactly. Even after the toxin is 00:24:34.809 --> 00:24:36.970 gone, they might need months of physical and 00:24:36.970 --> 00:24:39.730 occupational therapy to catch up on those gross 00:24:39.730 --> 00:24:43.170 motor milestones. A key nerding role is to incorporate 00:24:43.170 --> 00:24:46.329 passive range of motion exercises as soon as 00:24:46.329 --> 00:24:48.690 it is medically safe to prevent contractures 00:24:48.690 --> 00:24:53.130 and maintain joint mobility. OK. Moving to musculoskeletal. 00:24:54.179 --> 00:24:56.420 Osteomyelitis and septic arthritis. Infection 00:24:56.420 --> 00:24:59.599 in the bone. That's osteo or in the joint space, 00:24:59.819 --> 00:25:02.319 which is septic arthritis. Usually it's our old 00:25:02.319 --> 00:25:04.680 friend's staph aureus again. It travels in the 00:25:04.680 --> 00:25:06.660 blood and finds a nice place to settle down in 00:25:06.660 --> 00:25:09.880 the bone. The tricky part here seems to be diagnosis, 00:25:10.160 --> 00:25:12.460 especially in a pre -verbal toddler. A 10 -year 00:25:12.460 --> 00:25:15.140 -old can say, my shin hurts. A one -year -old 00:25:15.140 --> 00:25:17.400 can't do that. No, they can't. So you have to 00:25:17.400 --> 00:25:20.880 look for behavioral signs. The key term is pseudoparalysis. 00:25:21.079 --> 00:25:24.400 Bang paralysis. Exactly. The leg works fine neurologically, 00:25:24.400 --> 00:25:26.779 but it hurts so much to move it that the child 00:25:26.779 --> 00:25:29.380 refuses to use it at all. You'll see a baby who 00:25:29.380 --> 00:25:31.440 suddenly starts dragging one leg when crawling 00:25:31.440 --> 00:25:33.619 or who screams during a diaper change when you 00:25:33.619 --> 00:25:35.559 lift their hips. They hold it perfectly still 00:25:35.559 --> 00:25:37.839 to protect it. And the treatment is a marathon, 00:25:38.420 --> 00:25:41.740 not a sprint. It is. Bones have a relatively 00:25:41.740 --> 00:25:43.960 poor blood supply compared to other tissues. 00:25:44.440 --> 00:25:46.900 It's hard to get antibiotics into that dense 00:25:46.900 --> 00:25:50.339 tissue matrix. So oral pills often aren't enough. 00:25:50.660 --> 00:25:53.740 We are talking four to six weeks of IV antibiotics. 00:25:54.119 --> 00:25:57.720 That means a PICC line, a central line in a toddler 00:25:57.720 --> 00:26:00.890 for over a month. Which brings us back to family 00:26:00.890 --> 00:26:03.450 education and development. You are sending a 00:26:03.450 --> 00:26:06.009 two -year -old home with a tube going into a 00:26:06.009 --> 00:26:08.690 major vein near their heart. You have to teach 00:26:08.690 --> 00:26:10.890 the parents how to keep it sterile, how to flush 00:26:10.890 --> 00:26:13.529 it, how to administer meds. And socially. It's 00:26:13.529 --> 00:26:16.410 a huge disruption. That kid can't go to daycare. 00:26:16.710 --> 00:26:19.250 They can't play in the sandbox or the water table. 00:26:19.490 --> 00:26:22.470 And this hits right at Ericsson's stage of autonomy 00:26:22.470 --> 00:26:25.130 versus shame and doubt. A toddler wants to do 00:26:25.130 --> 00:26:27.670 things themselves. Now they are literally tethered 00:26:27.670 --> 00:26:29.490 to an IV pole. So what's the nursing action? 00:26:29.769 --> 00:26:31.930 You find ways to give them back some control. 00:26:32.150 --> 00:26:34.069 Let them use the non -affected limbs as much 00:26:34.069 --> 00:26:35.950 as possible. Let them choose which sticker goes 00:26:35.950 --> 00:26:38.390 on their dressing. Set up a safe play area where 00:26:38.390 --> 00:26:40.230 they can move around with the IV pole. It's about 00:26:40.230 --> 00:26:42.809 adapting the environment to support their developmental 00:26:42.809 --> 00:26:46.289 drive for independence. Next topic. Vector -borne 00:26:46.289 --> 00:26:50.250 diseases. Ticks. The creatures of nightmares. 00:26:51.210 --> 00:26:53.769 We have Lyme disease and Rocky Mountain spotted 00:26:53.769 --> 00:26:57.650 fever, or RMSF. Let's clarify the Lyme rash first. 00:26:57.849 --> 00:27:00.210 Everyone says bullseye. The official term is 00:27:00.210 --> 00:27:02.490 erythema migrans. It's not always a perfect bullseye, 00:27:02.569 --> 00:27:04.750 right? Right. It can just be a uniformly red, 00:27:05.049 --> 00:27:07.529 expanding rash, but the key is that it happens 00:27:07.529 --> 00:27:10.359 at the site of the bite. it starts small and 00:27:10.359 --> 00:27:12.440 gets bigger over days. Now I want to highlight 00:27:12.440 --> 00:27:15.599 a specific source accuracy note here. For years 00:27:15.599 --> 00:27:18.819 nursing students were told no doxycycline for 00:27:18.819 --> 00:27:21.319 kids under eight. Because of the risk of permanent 00:27:21.319 --> 00:27:24.400 gray staining on developing teeth, that was the 00:27:24.400 --> 00:27:27.019 dogma. But the tech says that has changed. It 00:27:27.019 --> 00:27:29.279 has. This is a major update. The AAP and the 00:27:29.279 --> 00:27:31.420 CDC both updated their guidance based on new 00:27:31.420 --> 00:27:33.900 evidence. They now support using doxycycline 00:27:33.900 --> 00:27:36.700 for kids of any age for line treatment, provided 00:27:36.700 --> 00:27:38.779 the course is short less than 21 days. Why the 00:27:38.779 --> 00:27:41.559 flip -flop? Because the data showed that these 00:27:41.559 --> 00:27:44.759 short courses actually have a very, very low 00:27:44.759 --> 00:27:48.160 risk of causing significant teeth staining. But 00:27:48.160 --> 00:27:51.180 the risk of untreated or undertreated Lyme, which 00:27:51.180 --> 00:27:53.579 can lead to chronic arthritis, facial paralysis 00:27:53.579 --> 00:27:56.500 called Bell's palsy, even heart block is severe. 00:27:57.099 --> 00:27:59.380 And doxycycline is the most effective drug. So 00:27:59.380 --> 00:28:02.059 the benefit now clearly outweighs the small risk. 00:28:02.359 --> 00:28:04.180 That is a crucial update. So if you are studying 00:28:04.180 --> 00:28:07.039 old flashcards, throw them out. Now compare Lyme 00:28:07.039 --> 00:28:09.619 to Rocky Mountain spotted fever. If Lyme is a 00:28:09.619 --> 00:28:13.009 slow burn, RMSF is a wildfire. It's transmitted 00:28:13.009 --> 00:28:15.609 by different dog ticks or wood ticks. The rash 00:28:15.609 --> 00:28:17.450 is different, too, right? Very different. And 00:28:17.450 --> 00:28:20.210 the location is key. It's a maculopapular or 00:28:20.210 --> 00:28:22.869 patechial rash, meaning it can look like red 00:28:22.869 --> 00:28:25.670 spots or little pinpoint bruises that don't blanch 00:28:25.670 --> 00:28:28.869 when you press on them. And the direction of 00:28:28.869 --> 00:28:30.869 spread is the exam question. It starts on the 00:28:30.869 --> 00:28:33.309 wrists and ankles. The extremities. Yes. And 00:28:33.309 --> 00:28:35.829 it spreads inward to the trunk. Most viral rashes 00:28:35.829 --> 00:28:38.910 start on the trunk and spread out. RMSF comes 00:28:38.910 --> 00:28:41.849 in from the limbs. And the urgency. Life or death? 00:28:42.710 --> 00:28:45.089 RMSF causes vasculitis inflammation of the blood 00:28:45.089 --> 00:28:47.410 vessels throughout the body. Kids can go into 00:28:47.410 --> 00:28:49.990 shock and die within days. You do not wait for 00:28:49.990 --> 00:28:52.309 the rash to appear or for labs to come back. 00:28:52.670 --> 00:28:54.910 If a kid is a fever, a severe headache, and a 00:28:54.910 --> 00:28:57.210 history of tick exposure in an endemic area, 00:28:57.609 --> 00:29:00.089 you start doxycycline immediately. You treat 00:29:00.089 --> 00:29:09.839 empirically. Let's do lice first. Pediculosis 00:29:09.839 --> 00:29:12.640 capitis. The big myth buster here is about hygiene. 00:29:12.920 --> 00:29:15.660 Yes. There is a huge stigma that needs to be 00:29:15.660 --> 00:29:18.240 broken. Parents feel ashamed, like, oh, my family's 00:29:18.240 --> 00:29:21.220 dirty. No. Lice actually prefer clean hair. The 00:29:21.220 --> 00:29:23.500 louse needs a clean hair shaft to glue its egg, 00:29:23.519 --> 00:29:25.700 the knit, to it. So getting lice has nothing 00:29:25.700 --> 00:29:27.559 to do with poverty or cleanliness. We have to 00:29:27.559 --> 00:29:29.500 destigmatize that for the parents. How do you 00:29:29.500 --> 00:29:32.579 tell a knit from dandruff? The flick test. Dandruff 00:29:32.579 --> 00:29:34.839 is flaky. It flicks right off. Knits are cemented 00:29:34.839 --> 00:29:36.420 on. You have to physically grab it with your 00:29:36.420 --> 00:29:38.099 fingernails and slide it all the way down the 00:29:38.099 --> 00:29:40.240 hair shaft. You have to remove it. OK. Scabies. 00:29:40.640 --> 00:29:42.039 This is the mite that burrows into the skin. 00:29:42.440 --> 00:29:45.240 It burrows under the top layer of skin to lay 00:29:45.240 --> 00:29:48.559 its eggs. And as it moves, it leaves these little 00:29:48.559 --> 00:29:52.000 linear tracks, these burrow lines. You see them 00:29:52.000 --> 00:29:55.500 most often in the webs of the fingers, the armpits, 00:29:55.559 --> 00:29:58.339 the groin, along the waistband. And the itch. 00:29:58.359 --> 00:30:02.000 It's an intense, maddening itch. And it's classically 00:30:02.000 --> 00:30:04.799 worse at night. That's when the female mite is 00:30:04.799 --> 00:30:07.490 most active. That's just nightmare fuel. And 00:30:07.490 --> 00:30:09.089 the treatment is the cream, but the application 00:30:09.089 --> 00:30:12.390 is very specific. Yes, permethrin 5%. You cover 00:30:12.390 --> 00:30:14.910 the child from the neck down to the soles of 00:30:14.910 --> 00:30:17.210 their feet, every single inch, under the nails, 00:30:17.390 --> 00:30:19.490 in the butt crack, everywhere. And you have to 00:30:19.490 --> 00:30:21.869 leave it on for 8 to 14 hours, usually overnight. 00:30:22.009 --> 00:30:23.829 If they get up and wash their hands an hour later, 00:30:23.890 --> 00:30:26.769 you have to reapply it to the hands. And remember, 00:30:26.930 --> 00:30:29.670 our master rule, treat the whole household. Right. 00:30:29.839 --> 00:30:32.119 And pinworms. The most common worm infection 00:30:32.119 --> 00:30:34.500 in the U .S. It spreads through a fecal -oral 00:30:34.500 --> 00:30:36.799 route. A kid scratches their butt, touches a 00:30:36.799 --> 00:30:38.819 toy, another kid touches the toy, then puts their 00:30:38.819 --> 00:30:41.339 fingers in their mouth. The cycle of life. Exactly. 00:30:41.740 --> 00:30:44.119 So the adult worms live in the gut, but at night, 00:30:44.319 --> 00:30:47.160 the female worm travels down and exits the anus 00:30:47.160 --> 00:30:50.299 to lay thousands of eggs on the skin right around 00:30:50.299 --> 00:30:53.240 the anus. Which causes the classic itchy butt 00:30:53.240 --> 00:30:56.069 symptom. Right. Pruridis Ani. And that leads 00:30:56.069 --> 00:30:58.829 to restless sleep. The kid is squirming all night. 00:30:58.990 --> 00:31:01.730 And the diagnostic test is legendary. The tape 00:31:01.730 --> 00:31:03.890 test. Explain it for the uninitiated. It sounds 00:31:03.890 --> 00:31:06.549 wild. It is, but it's effective. You tell the 00:31:06.549 --> 00:31:08.809 parents. First thing in the morning, before the 00:31:08.809 --> 00:31:11.329 child wakes up, poops or bathes, take a piece 00:31:11.329 --> 00:31:14.509 of clear scotch tape. Press the sticky side firmly 00:31:14.509 --> 00:31:16.890 against the anal opening, then remove it and 00:31:16.890 --> 00:31:19.650 stick it to a glass slide or put it in a Ziploc 00:31:19.650 --> 00:31:21.990 bag. Because the microscopic eggs will be stuck 00:31:21.990 --> 00:31:25.309 to the tape. Exactly. Low -tech, high -accuracy. 00:31:25.430 --> 00:31:27.670 And again, treat the whole family with medication 00:31:27.670 --> 00:31:30.450 like Mobendazole. Finally, let's touch on topic 00:31:30.450 --> 00:31:33.190 eight, sexually transmitted infections. This 00:31:33.190 --> 00:31:36.309 is an adolescent focus. Yes. And the big need 00:31:36.309 --> 00:31:39.329 to know here isn't a bug or a drug, it's legal 00:31:39.329 --> 00:31:42.900 and ethical. It's about confidentiality. So if 00:31:42.900 --> 00:31:45.119 a 16 -year -old comes into the clinic asking 00:31:45.119 --> 00:31:48.380 for an STI test, do we have to tell their parents? 00:31:48.720 --> 00:31:51.480 In most jurisdictions, no. The law recognizes 00:31:51.480 --> 00:31:54.039 that if we require parental notification, teens 00:31:54.039 --> 00:31:56.559 just won't get tested. They will hide it. And 00:31:56.559 --> 00:31:59.039 then the disease spreads silently. So nurses 00:31:59.039 --> 00:32:01.660 need to know their specific state laws. But generally, 00:32:02.079 --> 00:32:04.319 STI screening and treatment allows for minor 00:32:04.319 --> 00:32:07.220 consent. And clinically, what's the biggest danger 00:32:07.220 --> 00:32:09.759 for this population? Chlamydia and gonorrhea 00:32:09.759 --> 00:32:12.690 are silent destroyers. They are often completely 00:32:12.690 --> 00:32:15.890 asymptomatic, especially in females. If left 00:32:15.890 --> 00:32:18.329 untreated, the infection travels up the reproductive 00:32:18.329 --> 00:32:20.849 tract and causes Pelvic Inflammatory Disease, 00:32:21.190 --> 00:32:24.069 or PID. And PID is what causes the long -term 00:32:24.069 --> 00:32:27.410 damage. Yes. It scars the fallopian tubes. And 00:32:27.410 --> 00:32:29.890 that scarring is a leading cause of infertility 00:32:29.890 --> 00:32:32.910 and ectopic pregnancies years later. A completely 00:32:32.910 --> 00:32:35.869 preventable tragedy. So screening is vital. Absolutely 00:32:35.869 --> 00:32:38.190 vital. You can't treat what you don't find. The 00:32:38.190 --> 00:32:40.509 CDC recommends annual screening for all sexually 00:32:40.509 --> 00:32:42.450 active adolescents. We have covered a massive 00:32:42.450 --> 00:32:44.789 amount of ground. Let's move to section C synthesis. 00:32:44.990 --> 00:32:46.630 We need to tie some of these threads together. 00:32:47.210 --> 00:32:49.529 I want to give the listeners a cheat sheet for 00:32:49.529 --> 00:32:52.549 rashes. A rapid fire round. I describe a rash. 00:32:52.809 --> 00:32:54.930 You tell me the bug. Let's do it. I'm ready. 00:32:55.309 --> 00:32:57.700 Rash is a bullseye with central clearing. or 00:32:57.700 --> 00:33:00.380 just a big expanding red circle. Lime disease. 00:33:00.799 --> 00:33:02.819 Rash feels like sandpaper, it's on the trunk 00:33:02.819 --> 00:33:04.680 and extremities, and they have a strawberry tongue. 00:33:04.859 --> 00:33:07.220 Scarlet fever. Rash starts on the wrists and 00:33:07.220 --> 00:33:09.700 ankles, looks like little bruises, petechiae, 00:33:09.700 --> 00:33:11.900 and they have a high fever and headache. Rocky 00:33:11.900 --> 00:33:14.259 mountain spotted fever? That's a medical emergency. 00:33:14.680 --> 00:33:17.200 Intensely itchy rash with linear lines between 00:33:17.200 --> 00:33:19.640 the fingers and on the waistline. Scabies. Rash 00:33:19.640 --> 00:33:21.319 starts on the head and face and moves down the 00:33:21.319 --> 00:33:23.960 body like a shower of red spots. That's classic 00:33:23.960 --> 00:33:27.920 measles or rubeola. Okay, last one. Rash starts 00:33:27.920 --> 00:33:30.180 on the trunk and spreads outward to the face 00:33:30.180 --> 00:33:33.059 and limbs. It looks like teardrops on a rose 00:33:33.059 --> 00:33:35.779 petal blisters on a red base. That's varicella, 00:33:36.019 --> 00:33:38.819 chicken pox. That is a fantastic mental index. 00:33:39.619 --> 00:33:42.380 One more synthesis point. Fever meds. We have 00:33:42.380 --> 00:33:45.200 Tylenol, Motrin, and Aspirin. Let's lay out the 00:33:45.200 --> 00:33:48.460 rules. Okay, simple rules. Acetaminophen or Tylenol. 00:33:48.819 --> 00:33:51.319 Safe for all ages. From birth on, you just have 00:33:51.319 --> 00:33:53.900 to dose it accurately by weight. Ibuprofen or 00:33:53.900 --> 00:33:56.619 Motrin. Only for kids older than six months. 00:33:56.839 --> 00:33:59.079 And why the six -month cutoff? The kidneys aren't 00:33:59.079 --> 00:34:01.819 mature enough to handle the prostaglandin inhibiting 00:34:01.819 --> 00:34:04.500 effects of an NSIAD before then. You can risk 00:34:04.500 --> 00:34:08.099 kidney damage. Got it. And aspirin. Never. Never 00:34:08.099 --> 00:34:11.420 ever. Not for a viral illness. Aspirin plus a 00:34:11.420 --> 00:34:13.619 virus like the flu or chickenpox can cause Ray 00:34:13.619 --> 00:34:16.519 syndrome. It causes acute liver failure and brain 00:34:16.519 --> 00:34:19.889 swelling. It's catastrophic. The only time we 00:34:19.889 --> 00:34:22.730 use aspirin in PEDs is for very specific cardiac 00:34:22.730 --> 00:34:25.610 conditions like Kawasaki disease, and that's 00:34:25.610 --> 00:34:28.449 under strict cardiology supervision. Otherwise, 00:34:28.789 --> 00:34:30.989 keep the aspirin far, far away from the kids. 00:34:31.150 --> 00:34:33.809 This has been a masterclass. We've decoded the 00:34:33.809 --> 00:34:36.429 immune system of a neonate, the physics of a 00:34:36.429 --> 00:34:39.179 sneeze, and the life cycle of a pinworm. It really 00:34:39.179 --> 00:34:41.420 shows that infection control isn't just a checklist. 00:34:41.780 --> 00:34:44.599 It's biology, sociology, critical thinking, and 00:34:44.599 --> 00:34:47.159 critical care all rolled into one. Before we 00:34:47.159 --> 00:34:48.880 sign off, we like to leave the listener with 00:34:48.880 --> 00:34:50.900 a provocative thought, something to chew on. 00:34:50.940 --> 00:34:53.599 What's on your mind after all this? For me, looking 00:34:53.599 --> 00:34:56.199 at these sources, particularly the sections on 00:34:56.199 --> 00:34:59.719 measles and pertussis, we are seeing these awful 00:34:59.719 --> 00:35:01.900 diseases return that should be in the history 00:35:01.900 --> 00:35:04.920 books. We almost eradicated them. So the provocative 00:35:04.920 --> 00:35:07.599 thought is about the nurse's role in the era 00:35:07.599 --> 00:35:10.400 of vaccine hesitancy. It's a tough position to 00:35:10.400 --> 00:35:13.059 be in. It is. It is very easy to get frustrated 00:35:13.059 --> 00:35:15.500 or judgmental when a parent refuses a vaccine. 00:35:15.880 --> 00:35:18.699 But the challenge for us is, how do you educate 00:35:18.699 --> 00:35:21.980 without alienating. How do you build trust? Because 00:35:21.980 --> 00:35:24.320 herd immunity isn't just some abstract textbook 00:35:24.320 --> 00:35:27.000 term. It is the invisible shield that protects 00:35:27.000 --> 00:35:29.059 the little kid with leukemia in your waiting 00:35:29.059 --> 00:35:32.139 room who can't get vaccinated. Wow. Every conversation 00:35:32.139 --> 00:35:34.480 you have with a hesitant parent, every bit of 00:35:34.480 --> 00:35:36.820 trust you build that might lead to a yes, is 00:35:36.820 --> 00:35:38.860 potentially saving the life of another child, 00:35:39.079 --> 00:35:40.599 one you might not even be treating that day. 00:35:40.920 --> 00:35:43.500 That is a heavy silent responsibility that we 00:35:43.500 --> 00:35:45.559 all carry. That really puts it into perspective. 00:35:45.679 --> 00:35:47.199 It's not just about the chart in front of you. 00:35:47.260 --> 00:35:49.460 It's about the entire community. Exactly. We 00:35:49.460 --> 00:35:52.139 are the guardians of the herd. So to wrap up, 00:35:52.440 --> 00:35:54.880 let's recap the mantra for pediatric infection. 00:35:55.380 --> 00:35:57.880 What are the absolute must -knows? Keep them 00:35:57.880 --> 00:36:00.519 hydrated. Check the perfusion. And remember, 00:36:01.000 --> 00:36:03.280 cold babies are scarier than hot babies. Wash 00:36:03.280 --> 00:36:06.780 your hands. And never, ever mask a fever in a 00:36:06.780 --> 00:36:09.650 neonate until you've drawn the cultures. Perfect. 00:36:09.809 --> 00:36:11.530 Thank you for guiding us through this swamp. 00:36:12.050 --> 00:36:14.190 And to our listeners, good luck with the studying, 00:36:14.550 --> 00:36:17.170 watch out for ticks, and stay curious. Stay safe 00:36:17.170 --> 00:36:17.630 out there.
