Neurolept anaesthesia using etomidate as the hypnotic agent.
A technique of neurolept anaesthesia using etomidate (Hypnomidate; Janssen) instead of nitrous oxide is described in which a continuous infusion of 1 mg/kg/h is used to supplement droperidol, fentanyl and alcuronium. This totally intravenous technique eliminates theatre pollution, may offer haemodynamic stability and may be of use in patients with raised intracranial pressure. Pain on injection and muscle movements which occur with etomidate administration do not detract from the value of this technique.
