stages of anesthesiaThe distinct series of steps through which anesthesia progresses. The first stage of pharmacologically induced general anesthesia includes preliminary excitement until voluntary control is lost. Because hearing is the last sense to be lost, the conversation of operating room staff should be guarded during this stage. The second stage consists of loss of voluntary control. In the third stage there is entire relaxation, no muscular rigidity, and deep regular breathing. See also: anesthesia |
