Abstract
One avenue of research for a reliable monitor of anesthetic efficacy has been the computer-processed electroencephalogram (EEG), investigation being centered around derivatives of the power spectrum. Schüttler [1] has used the median frequency to control drug administration for closed loop anesthesia. However, the ability of power spectral derivatives to act as precise indices of anesthetic efficacy has not been consistently demonstrated. Rampil [2] showed that the 95% spectral edge may predict a hypertensive response to laryngoscopy, whereas Mills [3] was unable to correlate EEG and hemodynamic changes during induction, intubation, and skin incision and Dwyer [4] showed no correlation between movement at skin incision and several EEG power spectral derivatives during 1.0 MAC (minimum alveolar concentration to prevent movement at incision in 50% of patients) isoflurane anesthesia.
