So, while they were trying to reintubate Sam, they found a blockage.  It turns out he had a very severe mucus plug sitting on top of his vocal cords.  This plug was blocking his airway, making it difficult for him to breathe.  The moment the plug was out, Sam got a bit of his feistiness back and started to fight a bit with the doctors.  They went ahead and intubated him, just to give him a night off.  The doctor feels like they might be able to remove the tube tomorrow.

This roller coaster isn't day by day or hour by hour... right now it is minute by minute.
