Alfathesin and etomidate for minor outpatient anaesthesia.
Etomidate was compared with alfathesin for induction and maintenance of anaesthesia in a double-blind fashion in 48 fit patients undergoing minor gynaecological operations as outpatients. The patients were randomized to receive either etomidate 0.3 mg . kg-1 or alfathesin 75 microliters . kg-1 as intravenous induction agents. All patients received fentanyl 1 microgram . kg-1 and breathed 70 per cent nitrous oxide in oxygen. Cardiovascular changes were minimal in both groups and there was less depression of minute volume with etomidate. The incidence of side effects including pain upon injection, involuntary movements, and postoperative nausea and vomiting was higher following etomidate. Recovery was equally rapid in both groups. No adverse reactions were seen. Alfathesin would appear to be preferable to etomidate as an induction and maintenance agent in unpremedicated fit outpatients undergoing minor gynaecological operations.
