Auditory Evoked Potentials Compared With Bispectral Index for Monitoring of Midazolam and Propofol Sedation During Colonoscopy

Abstract

BIS and AAI correlated with the level of sedation. Hemodynamic variables were poor indicators of the hypnotic-anesthetic status of the patient. BIS discriminated best between moderate and deep sedation and could complement clinical observation for guidance of moderate sedation.
