Objective: Narrative objectives1 - Previous studies have shown that remifentanil affects three effect-site concentrations of propofol, the concentration at loss of responsiveness , the concentration at which the power in the alpha frequency band is maximal, and the concentration at which burst suppression patterns appear on the EEG - during the initiation of total intravenous anesthesia with propofol. In this study, we will investigate whether increasing the concentration of remifentanil further influences these three propofol concentrations. Basic objectives2 - PK,PD
