Comparison of a total intravenous anaesthetic technique using a propofol infusion, with an inhalational technique using enflurane for day case surgery

Abstract

A total intravenous anaesthetic technique with a propofol infusion for maintenance of anaesthesia was compared with an inhalational technique that used oxygen, nitrous oxide and enflurane in 98 unpremedicated patients who presented for day case surgery. Overall quality of anaesthesia during induction and maintenance was comparable in both groups. Quality of maintenance of anaesthesia in the propofol group was improved by an increase of the initial infusion rate from 12 to 15 mg/kg/hour. There was a larger decrease in arterial blood pressure after induction in the propofol group but no difference in blood pressure between the groups during maintenance. Recovery times and scores using the Steward scoring system were not significantly different. Nausea and vomiting were slightly less frequent in the propofol group. Copyright © 1988, Wiley Blackwell.
