General anaesthesia with intravenous flunitrazepam, continuous ketamine infusion and muscle relaxant. A preliminary report.

We present a preliminary report of an anaesthetic technique for abdominal surgery involving a combination of flunitrazepam induction and continuous ketamine maintenance of anaesthesia, specifically avoiding the use of any inhalational agents. Standard techniques of muscle relaxation, intubation and ventilation with oxygen-enriched air were employed.
