Comparison of two bispectral index algorithms in monitoring sedation in postoperative intensive care patients*

Abstract

The newer algorithm BIS XP did not perform better than the previous version BIS in patients after major surgery who were mechanically ventilated and sedated on an intensive care unit. This precludes the use of BIS or BIS XP for distinguishing, among deeply sedated ICU patients, those with and without preserved cerebral electrical activity.
