Narcotrend, Bispectral Index, and Classical Electroencephalogram Variables During Emergence from Propofol/Remifentanil Anesthesia

Abstract

We investigated modern and classical electroencephalographic (EEG) variables during emergence from propofol/remifentanil anesthesia. Modern EEG variables indicate changes of infusion in propofol, but not in remifentanil. Thus, modern EEG variables did not provide an adequate assessment of depth of anesthesia when remifentanil was used.
