Reply to comment by urzu_seven in During heart transplanting, how does the body survive before the heart is replaced? by harkhinz

30 days is the usual quoted upper limit of ECMO, but that's an estimate. Some patients can survive much longer on it, into the hundreds of days. There's a published report of one patient who was on ECMO for 605 days, and survived to recover.

I can assure you that I have personally had several patients on ECMO much longer than 30. Don’t think I’ve ever gotten close to 605 though!

Our son was at risk of needing ECMO and the main risk we heard at the time was a poor understanding of the temperature fluctuations in the blood supply could lead to cognitive or behavior complications later in life. Have you experienced that at all?

To be totally honest, I have pretty much zero experience with pediatric ECMO usage, just adults. In our adult patients, we have a controlled temp water bath connected to the circuit for temperature maintenance.

I believe they do it for the newborns as well, but the variations may have been enough.

He was on bypass for his surgeries and even that lead the surgeons to let us know he is at higher risk for ADHD for some reason they don't fully understand.

I wonder if there's a physical causation or if it's just, kids that go through something like that are being closely monitored by parents as they grow and so symptoms for ADHD that might otherwise be overlooked get caught more? How common is an increase in ADHD in similarly expansive interventions in other kids? But bodies are so weird, it being a physical impact that will one day be understood exactly how it works, I'd believe.
