    Something similar happened recently in Norway. A tourist was found severely cold in the mountains, in a storm where extracting him took hours. After a while hypothermia got to him, his heart stopped, and only 8 hours later they got it starting again, was technically dead for 20 hours. In this case, it looks to have gone well with the person afterwards.

    They say you're not dead until you're warm and dead.

      Wonder at which point we'll start adding PLB / airtags to clothing themselves. Decent jacket already cost way more than electronics. Satellite communications approaching cost of 0. If you venturing somewhere risky - kinda makes sense to have PLB built in.

    That is incredible. 2.5 hours underwater, 1.5 hours of CPR. They were instructed not to start rewarming him until he could be given more comprehensive treatment at a hospital. They list 'death' as a differential diagnosis...

    He didn't come out unscathed though. They describe his progress:

    > At 6-month follow-up, he was giving short commands, standing without support, riding a tricycle, eating soft foods, and relearning simple tasks. Peripheral neuromuscular weakness continued to improve.

    which is quite limited for an 8-year old, but remarkable considering the circumstances.

    • ekianjo 2 hours ago
      at this age the chances of continuous improvement are probably decent

    "Survival" here being, of course, not a black-and-white thing:

        > Outcome and Follow-Up

      Yes, I already feared that when I read "the child recovered" instead of "the child fully recovered" in the summary.

    I'd be curious to read about 1, 2, 5, 10, 20 year follow-up.

    Party pooper warning.

    I'm afraid I don't have rose tinted glasses, due to personal experience with a family member with TBI (accident at age 16, 3 weeks in a coma). The aftereffects are profoundly destabilizing to his environment. I sometimes have quite a dark view of people's need to be a rescuer and celebrate the "alive!", when they don't have to deal with the next 40-60 years of living...

    • thunfischtoast 2 hours ago
      I feel you, I also unfortunately have experiences with that. It has profoundly changed my view on living, especially how I want to be treated when someday I'm heavily sick.

      A family member in a coma takes a heavy toll on you, emotionally and financially. They are simultaneously there and not there. If they did not write down how they want to be treated you can never make a decision where you are sure what's right, or if they even want to be kept alive while not living. Eventually, when all your savings are burned through, when you might need to sell your house, you really wonder if that's what they wanted and if all that was worth it.

      For me, the decision is clear: when I'm not able to make my own decisions turn everything off and let me die.

        And what if you might be able to make decisions again tomorrow. Or the day after? Or in two weeks time.. ? These things are never all that 'clear'.

        • elmomle 2 hours ago
          The underlying idea here seems to be that if there's some chance of full recovery, one should not wish to be let go.

          Is it better for 100 families to live for years with a vegetative loved one with the most realistic hope being that a few to emerge profoundly affected and never their full selves again, or is it better for those hundred families to get to grieve?

          The pain of a loved one's continued quasi-existence, plus the difficulty of their life if they ever are to recover, make it so that the compassionate personal choice is to say "once the best estimated probability of my recovering robustly is clearly below P%, let me go". The value of P is a decision to be made carefully, and with deep consideration for ourselves, our loved ones, and for all of humanity.

          That's exactly why you write your own decision down, so other people don't have to live with making them for you.

      One of my children nearly drowned in the bathtub. She was already unconscious and floating on the water. She had stopped breathing. My wife (who was sitting only 3 meters away in the living room and had talked to her the minutes before) revived her. She made a full recovery in the hospital.

      I agree in principle. But: the aftereffects of nearly losing a child were already quite destabilizing to us, and still are, after several years. There is an overwhelming feeling that things can go catastrophically wrong, at any second, so why even do anything?

      I cannot imagine the effect of actually losing a child. I would go insane.

      In 1998, a 4-year old girl broke into a frozen pond in Austria [0]. She was found at the bottom of the lake after 30 minutes, with a body temperature of around 18 °C (so much higher than the case described in the article). She made a complete and full recovery (her story was filmed) and afaik lives a completely normal life as an adult now.

      While I don't know, I suspect the boy's parents do not share your views. He is able to ride a tricycle and improving.
      • theturtlemoves 1 hour ago
        Neither of us knows. That's the difficult bit in topics like these. None of us is psychic and can tell what'll happen next. Will he be happy and healthy? Or will he have anger issues, meltdowns or exhibit destructive behavior to himself and surrounding loved ones due to neurological damage? We always hope for the best. I hope the boy recovers well. But there are no guarantees in life.

          > anger issues, meltdowns or exhibit destructive behavior to himself and surrounding loved ones

          If we don't generally round such people up off the streets and kill them then we should also make a reasonable effort to save them if they're almost dead, I'd say. Feels easier to "let someone die" than to kill them but morally it's not so different.

        I'm not sure what you mean. I've been under general anesthesia a few times and not had any negative consequences. My dad has had multiple brain surgeries, and he's fully functional. Most people I know have been under at least once.

        I think before you blame anaesthesia it's worth wondering what else happened to you on the table, or whether something else might be causing you the problems. A lot of other things happen during a surgery that can screw you up pretty badly. I'm pretty sure I was dropped off a table once.

        • eru 1 hour ago
          Well, there's a small chance anesthesia can affect you negatively. Like all medical interventions, it can have side effects.

      • jimmymcgee73 2 hours ago
        Anesthesiologist here: what you are referring to exists, but is rare and is not related to general anesthesia (equally likely in operations performed while patients are awake with regional anesthesia or under general anesthesia). It is more people with pre-existing cognitive dysfunction that are elderly do not handle the inflammatory milieu generated by surgery. You can Google “postoperative cognitive dysfunction” for more information.

        Any phenomenon more widespread than the above is simply not supported by scientific studies to date.

        I’m honestly a bit disappointed to find this comment on hacker news, as I feel the level of discourse here is usually higher. I wish you all the best and hope you recover from whatever you’re experiencing, but this is frankly fearmongering.

        • cryzinger 2 hours ago
          If I'm understanding the "inflammatory milieu generated by surgery" part correctly, does this imply that the cognitive effects would be equally likely if surgery were performed without any kind of anesthesia? (Or to put it another way: the anesthesia isn't directly implicated, it's just that anesthesia and surgery tend to go hand in hand...?)

        Would you be willing to share more details, instead of this rather vague claim? I've had three at least 2 hour long operations last year. I kind of wondered if I'd notice any aftereffects, but apparently didn't. Even waking up was pretty uneventful, consciousness just coming back like a light bulb being turned on again.

        So either I am an exception, or your "everyone I know" needs qualification. In any case, I'd be very interested in what aftereffects you noticed, maybe that helps me reflect.

          One of the joys of private healthcare: I've seen general anaesthesia used to allow the patient to claim on their inpatient cover instead of their (exhausted) outpatient cover.

            Which end are we scoping? Colonoscopy is often done without anaesthesia but tends to take longer than 2 minutes, so I'm not sure if that's what OC is referring to. It's uncomfortable, but that's ok. Scoping nose/mouth->stomach also doesn't come with any drugs, just some lube.

            Conscious sedation, which is not the same thing as general anesthesia, is often used for endoscopy:

            I've done it (it's standard in many countries). Honestly, it's a bit horrifying because you are completely at the mercy of someone else but it's bearable. Colonoscopy is definitely easier.

            My only experience with global anesthesia was as a child waking up with a massive asthma attack unable to breathe so I try to avoid it.

      This is such a dark and dehumanizing take. I am disabled. I definitely had "destabilizing" effects on my environment when I grew up. These days, am as independant as possible. People from your train of thought would have aborted me. Your train of thought leads to what nazi germany already did. Yeah, an extreme example, I know, but following your attitude inevitably leads to very dehumanizing and egotistical takes. In fact, if you consider a family member a burden, please leave, you're the problem, not them.

      Oh shut the hell up! We are in the midst of massive technological revolution year on year especially related to biology and brain function. Yes, ALWAYS rescue someone. Treatment progresses it never stops or moves backwards.

      • rob74 1 hour ago
        If a patient has "sequelae of hypoxic ischemic changes" in their brain like in this case, that means a significant amount of their brain cells have died. The surviving brain cells may or may not be able to take over some of the function of the dead ones, but I'm not aware of any current or future technology that can significantly improve the chances of a positive outcome here.

        Then again, I agree with you on principle: if such a patient is brought into the ER, the Hippocratic Oath compels doctors to do everything they can to save them. And since ECMO is widely available (thanks Covid, I guess), they can really do a lot, even if the patient's heart is stopped for extended periods of time. If, like in this case, the patient's heart starts beating again, there's "only" the recovery of brain function to worry about. But there are also patients whose brain is working, but their heart doesn't anymore, so they only live as long as they're connected to the ECMO machine (until they hopefully eventually can get a heart transplant), which presents a whole new set of ethical questions...

      • theturtlemoves 1 hour ago
        > Treatment progresses it never stops or moves backwards.

        Unless the episode gets buried at the bottom of the medical file. Unless treatment is "completed" because no more progress can made. Unless insurance doesn't cover it anymore. Unless one bad doctor discourages the patient from ever seeking out another doctor again. Unless the patient himself has only dim awareness, if any, of the fact that this happened and impacts their behavior on a daily basis.

        Unless it really can't be fixed, no matter how hard everyone insists that in this day and age it should

        Unless they're "Lost to follow-up".

        Unless Unless Unless ...

      Weird! I wonder if there is some exponential complexity going on. More neural pathways leaving more stuff that can potentially break from an uneven freeze/thaw? Or is it literally that the freezing and thawing can't happen evenly when you're too big? A brief transistional period with unfrozen outsides and frozen solid insides is probably not great for you.

    As a layman, it’s kind of surprising that they attempted to CPR someone that long in this situation. If I pulled someone out of the water 2h after they went missing and they were cold to the touch, I would probably call the police and wouldn’t even ask for an ambulance.

      The article describes their decision making process:

      > As rescue divers searched for the boy's body, we deliberated whether to attempt resuscitation and likelihood of meaningful neurologic recovery of a child submerged for at least 90 minutes. We reviewed literature for guidance2-4,6 and drew from institutional experience with a 2-year-old submerged in ice water for 40 minutes who received 101 minutes of CPR.3 The toddler recovered with no sequelae. For our current patient, the decision was made to resuscitate and rewarm the boy because of his young age and protective effects of ice water submersion. We reasoned that if meaningful neurologic function were not observed after rewarming, end-organ preservation on ECMO may allow family goodbyes and organ harvest for transplantation to give other sick children the gift of life.9 This important point should be considered by providers faced with the difficult decision to attempt resuscitation of a patient with asystolic hypothermia >90 minutes.

    • kombookcha 1 hour ago
      I believe this is common to attempt when dealing with very cold water drownings. Obviously this is a very extreme case, but I believe you'd generally be instructed on the phone to start CPR but not try to heat them up until the ambulance arrives. Just in case.

      The case below had a person conscious in the water for 40 minutes (with an air pocket under the ice) before going into circulatory arrest, and then spent another 40 minutes clinically dead in under water. The combined 80 minutes in the water lowered her body temperature very dramatically, and played a large part in her almost complete recovery.

      There's been plenty of previous evidence that cold water immersion significantly slows down the destructive process caused by hypoxia in the brain. I don't think they'd have tried that had the boy stayed in a heated swimming pool for two hours.
  • mrtksn 2 hours ago
    Not the same thing of course but when our cat got sick with blood parasite, her blood turned to very diluted cranberry juice color and the body temperature dropped to almost room temperature(38C is the normal for cats) and the vet was double and triple checking the readings because it didn't make sense still being alive. After a few hours we were able to arrange a blood infusion and intensive care and by the morning she was "fine".

    By "fine" I mean alive, for months her character was much different. It took almost a year to return to its true behavior and enjoy the things she used to enjoy before. Even then she has much lower tolerance to unsolicited cuddling than before.

    The vet speculated that the low temperature was what kept her brain alive since the blood almost completely lost the ability to carry oxygen as a result of parasite attacking the blood cells(her initial symptoms were shortness of breath).

      Unlikely. The issue is cold and the speed of the cold. Children have a higher surface-to-mass ratio along with less subcutaneous fat which allows them to cool quickly. The article quotes the breakpoint:

        If water temperature is >6 °C (43 °F), survival is unlikely for submersion >30 minutes.
      
      And even still, it isn't like the child came out unscathed.

      CPR and a boatload of epinephrine, it seems.

      That passage bears quoting at length, it's where I really teared up:

      > At initiation of ECMO, the boy's rhythm was asystole. The boy was rewarmed with an ECMO heat exchanger-patient gradient ≤10 °C. [...] As the patient's temperature approached 22 °C (72 °F), low-frequency and low-amplitude sinusoidal electrical deflections were noted on his electrocardiogram. As the patient continued to rewarm, these phasic electrical deflections slowly increased in frequency and amplitude. At approximately 28 °C (82 °F), sinusoidal deflections organized into more classic cardiac electrical activity reminiscent of sinus bradycardia with a wide complex. Amiodarone, calcium gluconate, magnesium sulfate, bolus epinephrine, and epinephrine and norepinephrine infusions were administered. After further rewarming, sinus bradycardia developed and ultimately progressed to normal sinus rhythm...

    I am sceptical about the 147 minutes, the child could have still clinging onto the ice and just drowned a minute before the parents reached the pond.
    • ddeck 3 hours ago
      The timeline lists "Sled tracks seen to broken bond ice, EMS called" at 16:44. He was pulled from the water at 18:57. The article text further clarifies:

      Parents discovered sled tracks from home onto broken pond ice through which he fell.

      He left the house at 16:00, which is why they give the range of 147 to 177 minutes.

      • looofooo0 2 hours ago
        Yes but ultimatively it could been 16:43 to 18:57 which is 134 Minutes.
        • d1sxeyes 57 minutes ago
          The first two reported timestamps are 16:00 and 16:30 which both fall conveniently on the half hour. This leads me to conclude that these are guesses, and could be either early or late. It seems most likely that the mother was not exactly aware of the time the child left the house. There is an incentive to minimise (to avoid it looking like a failure of supervision).

          What we are certain of is the 16:44 call to the EMS, so you're right, 134 minutes is the lower bound. However, it's not unreasonable to assume that the parents did not immediately call on noticing the child missing, so the gap between 'noticing missing' and 'calling EMS' is real and non-zero.

          The gap between 'leaving the house' and 'noticing missing' is something I'm less clear on: how did the parents 'notice' the child was missing when he was knowingly allowed to leave the house earlier? There's still a non-zero gap between 'last sighting' and 'realisation that he's missing' (i.e. he definitely wasn't missing at ~16:00, when the mother saw him leaving the house... what changed so that the parents believed he was missing at ~16:30? Was he supposed to check in with Dad and missed the check-in, etc?)

          Either way, a difference of ±10% doesn't really make that much impact in interpreting the results.

      Ice-cold water won't let you have enough strength to cling to ice for two hours. Ten to fifteen minutes at most.

      Survivors of Titanic would say that the shouts of people clinging to something in the water died off pretty fast.

          Enahm Hof said the domestic violence conviction related to “a single incident involving Caroline’s son, adult at the time, for which Wim Hof expressed regret and offered an apology. Wim clarifies that no physical violence occurred, but a struggle, which nonetheless should not have happened.”

          that "no physical violence occurred, but a struggle" is an oxymoron for me. maybe no physical injury...
