Unfortunately, Iain is not tolerating Heparin.  He is bleeding again quite a lot.  Since they could not find anything specific it must be generalized oozing.  Since he is losing so much blood and continuous transfusions are not good either, the heparin must be stopped and a coagulant added.  This means the only real option is to wean him off the ecmo fairly rapidly (very early in the morning) and then back in the OR tomorrow morning.  Ultimately it means he has to rely on his new lungs and his heart much earlier than the experts wished.  So Sarah or I will update in the morning.

Thanks all, I am telling him about all your messages.
