Comparative evaluation of propofol and thiopentone for total intravenous anaesthesia

Department of Anaesthesia, Mount Sinai Hospital, University of Toronto, Ontario.

Sixty unpremedicated ASA physical status I or II patients scheduled for surgical procedures of intermediate duration (15 to 60 min) were studied to evaluate the safety and efficacy of propofol, to measure recovery times and to compare the return of psychomotor and cognitive function with thiopentone. Patients were randomly allocated into two groups. Anaesthesia was induced and maintained by either propofol (2.0-2.5 mg.kg-1 followed by a continuous infusion 0.1-0.2 mg.kg-1.min-1) or thiopentone (4.0-5.0 mg.kg-1, and infusion rate 0.16-0.32 mg.kg-1.min-1), titrated to patient response. Succinylcholine was administered to facilitate tracheal intubation and maintain neuromuscular blockade. Induction of anaesthesia was slightly longer with propofol than thiopentone (42.2 vs 29.8 sec) and was smooth with both drugs. Post-intubation increases in heart rate, and systolic and diastolic blood pressures were attenuated by propofol when compared with thiopentone. After the administration of propofol, times to eye opening (6.4 +/- 4.3 vs 13.9 +/- 15.9 min), response to verbal command (7.6 +/- 6.3 vs 15.4 +/- 16.6 min) and orientation (22.7 +/- 12.8 vs 36.2 +/- 23.1 min), were significantly shorter. Psychomotor and cognitive function returned earlier with propofol and fewer side effects were noted. At 24 hr there was no distinguishable difference between groups. Propofol is a safe anaesthetic agent with the potential for early patient discharge and street fitness after outpatient procedures.
