Abstract

A principal factor analysis was performed on EEG and AEP parameters, simultaneously recorded during anesthesia. The results showed that parameters from the EEG spectrum and the latencies of peaks In the AEP change with the level of anesthesia, while the amplitudes of the AEP reflect a balance between the sedative effect of anesthesia and the arousing effect of surgical stimulation. It is concluded that the EEG and AEP monitor different aspects of anesthesia.>
