A mixture of phenoperidine and haloperidol with inhalation of nitrous oxide-oxygen has been used to provide general anesthesia for gynecologic operations' in seven patients. The method afforded excellent hypnosis and analgesia together with remarkably stable circulation both during operative and immediate postoperative period. For operations requiring muscular relaxation a neuromuscular blocking agent had to be added. No central nervous system reactions (Parkinson-like, akathisia and cystonia) of an extrapyramidal type have been observed in the series.
