Abstract
Background: Sufentanil has been shown to act synergistically when combined with propofol, or when combined with potent inhalation anesthetics. The aiml of this study was to determine the dosing rate and target plasma concentration of propofol in the presence of low concentrations and to determine the impact of sufentanil infusion. Methods: Sixty patients undergoing a plastic surgery and urologic surgery were anesthetized with nitrous oxide, and given a target-controlled infusion (TCI) of sufentanil [target plasma concentrations of 0 (group 1) and 0.05 ng/ml (group 2)], and propofol at rates varying according to the bispectal index (BIS). The mean target concentration (Tc) and infusion rate of propofol according to the changes in the sufentanil concentrations were determined. The recovery time (from stopping the infusion to eye opening) and side effects were compared. Results: The induction time and recovery time were shorter in group 2 than in group 1 (P 25.2/kg/min, 4.1 0.8/ml) than in group 1 (161.7 26.9/kg/min, 4.7 0.5/ml) (P 0.8/ml and 0.05 ng/ml.
