Abstract:
0.05) . AEP index increased sharply from 42 to 67 when the patients regained consciousness (OAA/S increased from 2 to 3) but BIS increased gradually from 64 to 72 indicating that AEP index had better discriminatory performance. OAA/S correlated fairly well with BIS , AEP index and target-controlled concentration of propofol and r was 0.781, 0.684 and - 0.580 respectively. Conclusions Both AEP index and BIS can predict fairly well the level of sedation but AEP index prooes to be better in distinguishing conscious from unconscious.
