The Performance of Electroencephalogram Bispectral Index and Auditory Evoked Potential Index to Predict Loss of Consciousness During Propofol Infusion

Abstract
Both the bispectral index of the electroencephalogram and the auditory evoked potentials index are good predictors of the level of sedation and unconsciousness during propofol infusion. However, the auditory evoked potentials index offers better discriminatory power in describing the transition from the conscious to the unconscious state in the individual patient.
