State entropy and burst suppression ratio can show contradictory information

Abstract

Our results illustrate contradictory state entropy and BSR indices that may be relevant for anaesthesia navigation. Longer-lasting episodes may lead to incorrect titration of the depth of the hypnotic component of anaesthesia. Hence, our results demonstrate the necessity to monitor and check the raw EEG or EEG parameters that are less processed than the commercially available indices to safely navigate anaesthesia.
