[Comparative study between propofol and thiopental for anesthesia induction in surgery of short duration]

To compare anesthetic characteristics of thiopental and propofol in short duration surgical interventions, we have studied 40 patients undergoing gynecologic and proctologic surgery. Patients were randomly assigned to two groups receiving 2.5 mg/kg of propofol or 5 mg/kg of thiopental. In both groups, arterial hypotension of comparable intensity occurred. Heart rate was significantly higher in thiopental anesthesia. Postanesthesia recovery was significantly more rapid with propofol. Some of these results can be influenced by the different immediate premedication (atropine and diazepam in thiopental group) and duration of anesthesia.
