As an experienced medical professional, what were the risks associated with giving these boys and their coach anaesthesia in the cave environment? i think you have to be a cave dava or an anaesthesiologist to realize at a submerging an unconscious person for three hours and expecting that they're going to still be alive three hours later is fraught with peril. So i thought that for sure, these kids will e flood the mask and drown inside their mask at some point over that three hour journey. And under annacesa the water especially, strips heat from your body very, very rapidly.
