I think there is a definitional problem with "kids" vs "infants" vs "newborns" which are all difficult to define, the type of anaesthesia that was administered and we are also talking about 40 years ago. Our understanding of anaesthetics and heart surgery in newborns was much different than today. America definitely has a checkered and sordid past here and in psychiatry. But we also have a duty to be definitionally exact here which is why I tried to get a bit more context when the GP used the term "kids". I had thought before investigating that meant all the way up to teenagers.
