Study Arms:
- Placebo (Type: PLACEBO_COMPARATOR): Anesthetized volunteers will be allowed to wake after injection of either saline (placebo control) or caffeine (15 mg/ kg). The time to wake will be measured.
- Caffeine (Type: ACTIVE_COMPARATOR): Anesthetized volunteers will be allowed to wake after injection of either saline (placebo control) or caffeine (15 mg/ kg). The time to wake will be measured.
