Abstract :
A reliable anesthetic depth monitor for preventing intra-operative awareness has not yet been devised. In this study, a new monitor, FACE (Patient Comfort, Inc., Nevada City, CA) designed to track EMG activity in the four facial muscle groups (frontalis, corrugator, zygomaticus, and orbicularis oculi) was evaluated under clinical conditions of “adequate” and “inadequate” anesthesia. A derived variable, the awareness index, was found to be statistically significant when comparing awake (aware) and asleep (adequately anesthetized) subjects. Facial EMG monitoring may provide a clinically useful adjunct in the evaluation of anesthetic depth
