Total intravenous anaesthesia by an intermittent technique. Use of methohexitone, ketamine and a muscle relaxant.

Good quality anaesthesia with smooth recovery can be induced by methohexitone 40 mg, ketamine 100 mg, diazepam 5 mg and alcuronium 15-20 mg and maintained with methohexitone 30 mg and ketamine 10 mg at 5-minute intervals and controlled ventilation with 30% oxygen in air. The technique is economical in running and capital costs and may have special implications for avoiding atmospheric pollution, for use in developing countries, and in emergency situations.
