Comparison of Propofol Target Controlled Infusion (TCI) and Sevoflurane

Peripheral venous catheters were placed in all subjects. Subjects in the TCI propofol group had one specific intravenous catheter for propofol infusion apart from medication or intravenous fluid line. Subjects in the TCI Propofol group received TCI propofol (Schneider) with targeted Ce 4 -5 mcg/ml for anesthesia induction and maintenance. Subjects in the TCI propofol group received TCI propofol for anesthesia maintenance, Ce value was titrated until a targeted BIS score of 40-60 achieved.

subjects in the sevoflurane group were cannulated only with one venous catheter. Midazolam 0.05 mg/kg BW and fentanyl 1 mcg/kg BW were given as premedication. Subjects in the sevoflurane group received intravenous propofol 1 - 2 mg/kg BW.
