 The investigators carried out a modest trial with 8 test subjects. Each volunteer was anesthetized twice. Each volunteer was anesthetized one time and received an infusion of saline placebo control, without the aid of any other drugs and the other time the volunteer received an infusion of a relatively low dose of caffeine. The order of saline versus caffeine was randomized and the study was done in a double blind manner. We observed that emergence from anesthesia was significantly accelerated by the caffeine infusion. No adverse events were observed.
