Recovery from day-case anaesthesia: Comparison of total i.v. anaesthesia using propofol with an inhalation technique

Abstract

A prospective, double-blind study was conducted to compare postoperative recovery after either total i.v. anaesthesia (TIVA: propofol and alfentanil) or an inhalation technique (propofol and alfentanil followed by nitrous oxide and isoflurane) in 50 patients undergoing day-case gynaecological surgery. Psychomotor performance was assessed at 1 and 2 h after surgery using the Critical Flicker Fusion Threshold (CFFT), Simple Reaction Time (SRT) and Choice Reaction Time (CRT). Subjective recovery and side effects after discharge from hospital were assessed using a postal questionnaire. Recovery occurred significantly earlier in the TIVA group as assessed by CFFT and SRT (P < 0.01 ); there were no significant differences (P > 0.05) between the two groups in CRT, subjective duration of recovery or side effects. © 1992 British Journal Anaesthesia.
