""The worst-case scenario is that you wake after a sub-anesthetic dose of sodium pentothal. [You've already received] a paralyzing dose of Pavulon -- and experience the torment of suffocation and conscious paralysis -- and then the agony of the burning potassium chloride," says Mark Heath, an anesthesiologist at Columbia University Medical Center in New York. "There are abundant examples of people who wake up in the middle of surgery feeling everything -- having the full experience of pain and terror, but [because of the Pavulon] are unable to communicate in any way that they're awake.""
Maybe they should just ut duct tape on the convicts mouth, give him the Pavulon and then the family can repeatedly stab him until he is dead.
Or just forget the valium and put a bullet in the back of his head.
