- 0:18This is my first time back in the podcast studio after an unintentional injury.
- 0:25Unintentional injuries are the leading cause of death in children.
- 0:30And in my case, it was a snow skiing accident over spring break.
- 0:33And I credit the doctors at UT Health for saving me.
- 0:38Makes me emotional to think about it. So I'm not going to talk about it too
- 0:41much, but it's great to be back.
- 0:43And I'm here with one of our amazing doctors on the pediatric side. It's Dr.
- 0:49Ted Wu. Dr. Wu, thank you so much for being here in this podcast studio on Pediatrics Now with me.
- 0:57Thanks for inviting me. It's such a tough topic, the unintentional injuries
- 1:02that you see often as the director of the PICU and a professor of pediatric
- 1:09critical care. You've been doing this for 19 years.
- 1:13You see the drownings, near drownings.
- 1:17What do you want to say about that right off the top? Yeah.
- 1:20I mean, it's one of the most preventable things that we can do.
- 1:24I mean, in pediatrics, we always echo that prevention is like our number one
- 1:29education to our families and parents and caregivers, right?
- 1:33So being, you know, it's the summertime now and everyone's out and about enjoying
- 1:38the pool or being close to water.
- 1:40So having a strategy and talking about who's going to watch over the kids while
- 1:45they're playing in the water is a much needed role, right?
- 1:48And, And, you know, we all enjoy being around the water and enjoying drinks as well. So I get it.
- 1:55But having a designated role, like we would have a designated driver,
- 1:58we would have a designated role that would watch the kids as they play in a
- 2:02pool or within, you know, a body of water as well.
- 2:05So I can't echo enough about the necessary kind of role for prevention,
- 2:11right, for against drownings as well.
- 2:14Because it can happen in seconds. Yeah, the cases that we see,
- 2:18unfortunately, you know, that come to our pediatric ICU are,
- 2:21yeah, it's always, the stories are all very similar.
- 2:25Toddlers missing for five minutes, you know, just walked off.
- 2:30And the next thing you know, they're
- 2:31on the bottom of a swimming pool and everyone's rushing to get them out.
- 2:36They start some sort of CPR if they know any of it.
- 2:41And yeah, EMS comes about and, you know, they usually get a heart rate back
- 2:48in that resuscitation, those critical like 10, 15 minutes.
- 2:52But that drowning time, water time, that's very variable. And that's,
- 2:57you know, because it's subjective, right? No one's timing.
- 3:00No one's actually witnessed when it happens. So we kind of don't know when that
- 3:05amount of time that we call anoxia or that time of lack of oxygen to the brain,
- 3:10we don't know what that time is, you know, and we know once 10 minutes of anoxia happens,
- 3:15then the brain starts having all these cascades of injury to it.
- 3:20And part of ICU care is kind of limiting the injuries.
- 3:24We're going to talk about advances in post-cardiac arrest care.
- 3:29But before that, since it's summertime, for our pediatric practitioner listeners
- 3:34here in the United States and wherever in the world where you're listening,
- 3:38where it's warm weather and people are swimming, is it something that should
- 3:42be mentioned to every patient in the precious moments in the exam room or what's
- 3:46your advice? Yeah, exactly.
- 3:48I mean, that's where I remember being a general pediatrician is in the early
- 3:52months or even during the summer months.
- 3:54So starting in April, May, when it starts getting warm and people are going
- 3:58towards the pools or even during the summer months is they put in the reminder.
- 4:03Right, of, hey, if anyone's going toward the water, making sure everyone's being properly observed.
- 4:10Right. So I'm being safe. And then I know we're pediatricians out there that
- 4:14are doing it because I don't see it as often. but it does happen in a warm state like Texas here.
- 4:20So always an opportunity as part of our, what we call anticipatory guidance
- 4:26for our pediatricians, right?
- 4:28And it should be part of their talk during the summer months.
- 4:32And I was reading that 87% of the drowning deaths happen in pools.
- 4:40Involving kids age one to four. And then for older kids, it's in open water
- 4:46where they're drowning. Yeah.
- 4:47Well, with older kids, it becomes a little bit more cloudy because there's always
- 4:52a mixture, goofy mixture of drugs and alcohol mixed with that.
- 4:56But yeah, you're correct. I mean, a lot of open water, water sports.
- 5:01So we'll have teenagers, you know, doing flips and dips and slides on water,
- 5:07you know, boats and all that.
- 5:09So, yes, then we'll see those types of injuries.
- 5:12Wear the life jacket. Yeah, wear the life jacket. State law.
- 5:16Yeah, state law, you know, for all kids.
- 5:19And I get it. 18 and under, right? Yeah, exactly. So, I get it.
- 5:23There's sometimes with teenagers, it's like wearing a helmet.
- 5:26It's like you're the kid with the helmet and the life jacket,
- 5:28you know, but it's those little kind of reminders for our kids to do those preventative,
- 5:34you know, safety measures. And it saves lives. Yeah, when we do that.
- 5:39And when it's for the younger kids in pools or hot tub, instead of everyone
- 5:44watching the kids, it's one person.
- 5:46You're the person in charge.
- 5:48Or even there's bracelets you can get online or where you could hand off to
- 5:53that person. You're the person watching the child or children in the water.
- 5:57Yeah, yeah. There's a lot of different techniques. You're right.
- 6:00There's either a bracelet or a baton, like flat out, like it looks like a baton.
- 6:04And you are the person that's concentrating on watching everyone in the pool.
- 6:09Yeah. So especially at pool parties. Yeah. So those are some strategies as well.
- 6:13There are some things out there, I don't know, part of your research that looked
- 6:17at safety alarms of when kids, that the kids would wear if they would,
- 6:23you know, fall into the pool.
- 6:24That alerts families on their phones when that happens.
- 6:29Those haven't been validated. They have pretty good marketing in them,
- 6:33but not really validated.
- 6:35So that could be something that could be an option where they wear it in the
- 6:40water. And when they the kids wear like it comes in a like a onesie of some sort or a bracelet.
- 6:47Yeah, as well. And it alerts them when they go into the pool,
- 6:50alerts the parent that they're in the pool.
- 6:53Wow. Yeah. So, again, it's it's not quite validated quite yet,
- 6:58you know, because it hasn't gone to scale.
- 7:00Yeah. So but it is in the efforts to kind of eliminate drowning. Yeah.
- 7:05And then it's like or does it create a false sense of security?
- 7:09Right. Exactly. You just can't be. It'd be another layer, not in place of watching.
- 7:15Correct. Correct. It's another layer of complexity.
- 7:18Are you watching your phone versus just flat out just watching your kid or the
- 7:22kids, you know, playing out in the pool? Right. Yeah. So.
- 7:29I was saying, as a news reporter, we knew so many accidents were going to happen.
- 7:32And it's just, and I know as a critical care doctor, you knew the same.
- 7:36And you guys were, you said, holding your breath.
- 7:38And then, in fact, was it that weekend that a child drowned? Yeah, yeah.
- 7:43It's always like holiday weekend that occurs and where, you know,
- 7:47family and friend gatherings are occurring.
- 7:49Yeah, usually that's when it happens. Yeah, so.
- 7:52And we, did San Antonio see a drowning that weekend or was it just recently?
- 7:57I know there was a child drowned in the spring time, right?
- 8:01Yeah, there's springtime and there was another one, yeah, recently as well.
- 8:06So, and we're only just one hospital.
- 8:09So in the area, there's quite a bit, you know, in the San Antonio area,
- 8:14you know, because we have so many other hospitals here.
- 8:16In talking to the families, is there a common thread or anything that you want
- 8:20to mention to pediatricians to like, do they, are they saying like,
- 8:24I thought someone else was watching. or I just turned away for a second.
- 8:28Yeah, it's always kind of that moment of opportunity that they're distracted.
- 8:34And we live in such a distracted world with our phones.
- 8:39But yeah, it's in all kinds of scenarios.
- 8:43Sometimes they're freakish, you know, in the sense that, oh yeah,
- 8:46I understand if there's another child that they're watching over that's younger,
- 8:51they're watching over them and they're running off.
- 8:53You know, it is an element of distraction. and the timing is right on, you know.
- 8:59So, but it's never, it's seldom just one person, right?
- 9:02If it's just one person watching over the kids, actually that works out okay.
- 9:07It's when a group of people who make the assumption that the other person is
- 9:11watching or if it's, yeah, it's just being distracted really easily.
- 9:17Yeah, so. That's a great point, Ted.
- 9:20I remember when I was a news reporter and we were rushing to the scene where
- 9:24it was in that body of water near the zoo and it was a party happening over...
- 9:30It was Easter Sunday. Oh, man.
- 9:31And it was a nine-year-old who ended up... Who drowned.
- 9:36And I remember getting there and the emergency...
- 9:41People in the water who they had their wetsuits on. And I just remember getting
- 9:46there and it was so quiet and they
- 9:48were getting out of the water and everything. Like, why is it so quiet?
- 9:52And then it was just like, just so heartbreaking. I'll never forget that moment.
- 9:57But it was that where the family was saying, we all thought someone else was
- 10:02watching her and she didn't know how to swim very well.
- 10:06Well, you all are doing such a wonderful job helping children,
- 10:12and we're talking about advances in post-cardiac arrest care.
- 10:17So what are some of the advances you can tell us about? Yeah.
- 10:20So, you know, this kind of comes up from a couple decades worth of literature.
- 10:26What we found was in adult patients that had cardiac arrest,
- 10:31when they used hypothermia after their care or in their care afterwards,
- 10:35they had better neurologic results.
- 10:39They had less disability and mortality from that.
- 10:43With that knowledge, they applied it to babies with suffered birth asphyxia,
- 10:49and they had extreme acidosis when they were born.
- 10:53And when they used hypothermia in the first 72 hours after that birth,
- 10:57they also encountered less morbidity and mortality as well.
- 11:03So a group of us in pediatric critical care now about 10, 15 years ago decided
- 11:10to use the same type of therapy, which is using hypothermia for pediatric cardiac arrest.
- 11:16I actually was doing training in fellowship in California.
- 11:19And again, my attendings and faculty were like, we have a lot of drownings here, you know.
- 11:25And can, is there any utility using hypothermia to lessen the injury from this
- 11:32anoxia to the patient's brains.
- 11:35So it took a while to formulate, but basically we formulated the largest pediatric
- 11:40cardiac arrest group all around
- 11:42the country, and in fact, extending to Canada and Australia as well.
- 11:47Wow. So our first study is called the FAPCA studies, and that's an acronym standing
- 11:52for Therapeutic Hypothermia After Pediatric Cardiac Arrest. arrest.
- 11:58And that was looking at cardiac arrests, whether they happened in hospitals
- 12:02or outside of the hospital, and just compared using hypothermia and normalthermia.
- 12:09And what the past studies had shown was comparing hypothermia versus nothing.
- 12:16And they had showed better outcomes when those studies.
- 12:20But when we compared it just to normalthermia, there was actually no difference.
- 12:24So what that meant to us was that,
- 12:28It was really critical to protect patients' brains after their cardiac arrest
- 12:32and not get them hyperthermic, not having fevers afterwards,
- 12:37and to control their temperature.
- 12:39So this is where we call it targeted temperature management, TTM.
- 12:44So that's one of the major developments that we've seen now that has good outcomes
- 12:50in protecting patients' brains.
- 12:52So, Ted, that's so fascinating. And what does that look like?
- 12:57So say if a child's pulled from the water. Yeah.
- 13:00So once they're pulled from the water, they're actually usually pretty cool.
- 13:05Then their temperatures are usually in the 92, 93 degrees.
- 13:09And a lot of our practice now is we don't actively warm them.
- 13:13In the past, we would actively warm them back to normal, which is 97, 98.
- 13:17Now we just let that be because we kind of think it's protective in that form, right?
- 13:23And then when they come to the ER, and we work with our ER colleagues now to
- 13:28activate cooling then, as soon as we can put them in some kind of,
- 13:32we call it thermal blanket,
- 13:34we wrap them in this blanket that's laced with water that is actively cooled
- 13:40or warmed, depending on what the target temperature is.
- 13:43So we do that starting in the emergency room and then we continue it to the ICU care.
- 13:50So hypothermia and its use has been used for a lot of other diseases,
- 13:55but cardiac arrest seems to be the most benefit of protecting the brain.
- 14:00It's so interesting where it's hypothermia can be its own emergency.
- 14:05It's like inducing this pain.
- 14:07Emergency to help save someone and to help save their brain.
- 14:11Yeah. I mean, it came from, you know, the old tales where, you know,
- 14:15the kid in Lake, you know, drowned in Lake Michigan in the middle of winter
- 14:18and was down for like 30 minutes.
- 14:21The divers were going in, they pulled them out and came back and it was absolutely normal. Right.
- 14:27And there were some studies that did older studies that looked at that and found
- 14:32that when they cooled patients too long for like a week, they had worse outcomes.
- 14:38They had worse outcomes with that.
- 14:40So we found out there's probably some utility in using hypothermia,
- 14:46but probably not too long.
- 14:48It has to be the exact right amount. Yeah. And what the right exact amount, we don't know.
- 14:52So that's actually where we're involved now. Now, the same hospitals that did
- 14:56the THAPCA studies are doing now what we call a pediatric ice cap study.
- 15:00And it's just looking at, we initiate hypothermia for also pediatric cardiac arrest patients.
- 15:06And they're usually drowners or near drownings.
- 15:09And then cooling them and they get randomized to the duration.
- 15:14So they all get hypothermia, but the duration is where they randomize.
- 15:17To see where the optimal time duration to optimize or lessen their injuries when we look at them.
- 15:27So we will enroll these patients and we follow them a year later.
- 15:32Have them evaluated by our neurologist.
- 15:34And we have a developmental pediatrician who also evaluates them as well,
- 15:39just to kind of see what outcomes come out of that.
- 15:42So that's ongoing right now. And because a lot of families may not realize that
- 15:46the child survives, that child may have long-term brain damage.
- 15:51Yeah, brain damage, a lot of developmental disabilities, you know,
- 15:54some disability, and it ranges. That's the hard thing to predict, right?
- 15:58Some could be, you know, not able to walk properly.
- 16:03Some might lose, you know, the ability to speak well, you know,
- 16:06but we don't know what happens with what.
- 16:09There's no enough brain imaging to kind of help predict that as well.
- 16:13We just kind of teach our families that these injuries happened,
- 16:17and then kind of get them to therapy and rehab to help, you know,
- 16:21train or, you know, get those abilities back.
- 16:25But it's hard with toddlers because with toddlers, we kind of didn't know because
- 16:29they're developing as well.
- 16:30So we didn't know what they could developmentally do anyways.
- 16:34Right. So, but we try to optimize that while they're recovering.
- 16:39Music.
- 19:23Or cardiologists follow, those are the ones that also have cardiac arrests outside of the hospital.
- 19:30Okay. And I saw that San Antonio now has its first confirmed case of measles
- 19:36and pneumonia is, I think, the most common side effect of measles.
- 19:41And hopefully pneumonia will not become more common as we see more cases of measles.
- 19:47It's so awful, heartbreaking. Yeah. Yeah.
- 19:50Yeah. I mean, as our unvaccinated rates go higher, yeah, we're going to see
- 19:56more measles cases. Yeah.
- 19:58So. And we do have an episode here in the Pediatrics Now News Feed.
- 20:02The episode right before this is a COVID update.
- 20:05And we talk about COVID and flu shots with our pediatric infectious disease
- 20:09doctor and advice on what does science show, what to say to patients in that regard.
- 20:15Ted, is it good for all of us to have cold water, a cold water plunge or get in the cold water?
- 20:22Do you want to say anything there? Do you try to do that? No.
- 20:26I mean, I've done half marathons or trained for them. You know,
- 20:31I've heard the whole ice cold plunge.
- 20:34I've also read the literature. There's a lot of sports physiology about swimmers
- 20:38that swim in cold water, like truly like frigid water.
- 20:42And there is some benefit in definitely making decisions
- 20:50energy efficient for oxygen consumption for your muscles, right?
- 20:53They don't know if there's some anti-aging effects in that, but I know swimmers,
- 20:59as we talked about, you know. Yes, we're both swimmers. Yeah.
- 21:02And they live long lives because of that. But that science is really out there.
- 21:08So there's still more to come about that. Yeah. So. My son did an outward bound expedition in January,
- 21:15which I highly recommend, But he went to an area called the Boundary Waters
- 21:19in Minnesota, and it was seven days of dog sledding and cross-country skiing.
- 21:26And then at the end, they go into the sauna, and then they do a cold plunge.
- 21:32And the maximum I think you could do the cold plunge was stay in for two minutes,
- 21:36which he got very close to that. But he loved it.
- 21:38He loved it. That was his favorite part. Oh, wow. There you go. And he wants to go back.
- 21:44So ted it's such an honor to be talking to you here today and i so appreciate
- 21:49you being here in the podcast studio how are things going in the pic you are there any other,
- 21:54unintentional injuries you want to mention i mean you know in the pic you especially
- 21:59during the summer seasons all of the preventable diseases are preventable injuries
- 22:05which are burns and sunburns?
- 22:08No, burns from fireworks and outside gatherings, right?
- 22:13As we lead into the 4th of July weekend. Right, exactly. So fireworks is the big thing.
- 22:19In San Antonio, they are illegal, but outside it is, you know, open flames, I guess.
- 22:26But yeah, that's a lot of where our injuries see from our, you know,
- 22:30from toddlers, you know, handling, you know, fireworks or sparklers,
- 22:33Or teenagers too Or teenagers too, right, exactly And with the teenagers then it gets with
- 22:40open fires and adding gasoline to them. We'll see those.
- 22:45They add gasoline to the fire? Yeah, they add gasoline to the fire.
- 22:48They'll see someone do it, but not knowing how much to do.
- 22:53And that's actually still really dangerous to do.
- 22:56And the grill and being safe around that. So we'll see various injuries related to fire in that.
- 23:04The other one is just flat out family travel, right?
- 23:06Making sure all the kids actually are in car seats and not sitting in a family
- 23:13member's lap because we see a lot of those types of accidents during the holiday weekend as well.
- 23:19So mentioning that, having everyone kind of in a buckle seat and it's not worth
- 23:24the, you know, the cram seating in those situations, you know,
- 23:29and having, you know, your loved one get really injured because of that, you know.
- 23:33So those are the types of things that we'll see during the summertime right now.
- 23:38And you're on call tonight, right? Yeah, I am on call tonight, yes.
- 23:41I so appreciate you being here as we head into this holiday season,
- 23:45which is that travel's already started.
- 23:48Yeah, right. That's true. So we'll see.
- 23:51What else would you like to say to the pediatric practitioner listener?
- 23:54I think it's so incredible and inspiring that we are seeing fewer drownings,
- 24:00thanks in a huge part to pediatric practitioners mentioning something to families in the exam room.
- 24:06Yeah, you know, I think, you know, as our good general pediatricians are out
- 24:11there, you know, counseling our families, never underestimate your advice.
- 24:18It still carries a lot of weight.
- 24:20Sometimes I feel that our pediatricians might feel that they,
- 24:24you know, there's so much information out there and it's so accessible.
- 24:29But the pediatrician still has a lot more weight in ways that you probably don't
- 24:35know and just being receptive to your families and what they're trying to tell you.
- 24:41If they, sometimes if a parent or the patient have suspicions of things,
- 24:47it'd be a good opportunity to kind of really delve into that.
- 24:50I know sometimes it's really busy to kind of go into the details of things but
- 24:54I think sometimes it's worth the time to kind of delve into more of that and that's where we run in.
- 25:00For us in the ICU, we see the patients have gone to the pediatrician X amount
- 25:05of times and didn't really identify.
- 25:08And they have very vague symptoms. I get it. And how do you.
- 25:13Weed out all of that, you know, but some, some of our pediatricians out there
- 25:17are able to kind of able to ask the right questions and really figures, help figure things out.
- 25:23So I think being attuned to that is a good opportunity to talk to your families
- 25:28and your patients to do so.
- 25:30So, and I know with, with my three kids, I'm every time there might be something
- 25:35that I've been talking to them about.
- 25:37And then when the pediatrician says it, then they really, that's
- 25:40when they really start doing it you know there is that power
- 25:43and then we do have a couple of
- 25:46episodes in this news feed on motivational interviewing which can
- 25:49really help you drill down in that short amount
- 25:52of time in the exam room you have to really get to
- 25:55the heart of the matter which it can be so tough like you're saying well
- 25:58the funny thing about that is that so my wife and
- 26:01I are both pediatricians and even with our kids
- 26:04we we tell them hey we're gonna let doctor are
- 26:07you know your pediatrician know that you're doing this and
- 26:10then they're like no no no no no don't let her know oh that's good
- 26:13yeah so i was like see you know i so the
- 26:16pediatrician does have a lot more you know weight
- 26:19you know outside the parent right you
- 26:22know so that's great yeah my son
- 26:25was so he he had listened to the
- 26:27both of our motivational interviewing episodes or the
- 26:30all three of the motivational interviewing episodes and then
- 26:33i was asking my older daughter about something and then he's like mom why did
- 26:37you ask a closed-ended question which is part of it i'm like oh yeah why did
- 26:42i and it's a lot of in motivational like interviewing reflecting back like so
- 26:48what you're saying is all right and then repeating back so you're understanding it yes so.
- 26:54Ted, before we wrap up, do you want to talk about, I like to promote doing stuff
- 26:59outside of medicine in this high burnout, high stress career. I know you swim.
- 27:06Is there anything else you want to talk about that you do for fun?
- 27:09I actually golf, you know, for my fun. I
- 27:12like the nature of it's it's so
- 27:15hard and difficult but I like
- 27:18it because there's not time where you
- 27:20can spend so much time outside outside of hiking and
- 27:24but but you're kind of always I like how it
- 27:27engages your mind and you're trying to
- 27:29figure things out it's all every every hole is a
- 27:32puzzle once you get part past part the
- 27:35part of how to you know hit your golf ball and control it
- 27:38but then there's so many other things to it
- 27:41that's it's so engaging and
- 27:44and mind-boggling so that part i really
- 27:47enjoy the swimming part for me is just not only to maintain some fitness and
- 27:52stamina but it's also a quiet time as well right so i really enjoy that that
- 27:58moving meditation yeah exactly outside that yeah it's really you know daddy
- 28:03time with with the kids that's kind of how I maintain some balance there.
- 28:07So, yeah. And you're a father of two? Yes. Yes.
- 28:11And did you and your wife meet in medical school?
- 28:14We met during training. I did my training in Las Vegas, Nevada. Yes. So, yeah.
- 28:19And then were you friends first or do you want to talk about that at all?
- 28:23Yeah, we were friends first and then we didn't actually start dating until after training.
- 28:28Yeah. And then I moved. So I had to do additional training after that training
- 28:33and that moved me to Southern California. at Loma Linda.
- 28:36So it was not until then we were, we were dating. So, yeah.
- 28:41So, and you were talking about golf. My, my son, I've been playing with him
- 28:45some, and he told me like, it takes a lot of work to just get to where you're
- 28:49bad at golf, but you're playing actually.
- 28:51I'm like, oh, great. It's like a little bit intimidating.
- 28:55So that's my first goal is to at least be playing, but be bad at golf. Yeah.
- 28:59Right. I guess. Yeah, exactly. So there is like This threshold where you put
- 29:05in a lot of work just to hit the ball, hit it in some fashion that's consistent.
- 29:12But it is so beautiful to be out there. Yeah, I know.
- 29:16And Texas is awesome for golf. It is hot, though, but it is pretty awesome for a lot of the golf here.
