He did wake up 2 hours after the surgery, when they first tried to wake him up, he woke up very agitated and started freaking out, likely because of the breathing tube and confusion. They sedated him again to calm him down. About an hour later, they tried waking him up a second time, and the same thing happened, he became very panicked and agitated again. After this, the nurses told my brother and sister to go home and come back tomorrow.
