Randomized Controlled Trial Comparative Study Clinical Trial
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. ⋯ 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.

Comparative Study
Increased neonatal risk from the use of general anesthesia in emergency cesarean section. A retrospective analysis of 374 cases.
Three hundred seventy-four consecutive cases of cesarean section were reviewed retrospectively for differences in neonatal outcome with respect to method of anesthesia used. In 205 elective sections no difference in neonatal outcome was observed irrespective of anesthesia method. ⋯ These preliminary results suggest that general anesthesia may increase the degree of central depression of the fetus already compromised by hypoxia before surgery. An investigation of this question on other sets of data and in a prospective trial should be done.

We report a patient with Duchenne muscular dystrophy who developed malignant hyperpyrexia during general anaesthesia. During anaesthesia bradycardia was followed by ventricular fibrillation, on which ventricular flutter supervened and a body temperature rise of 0.6 degrees C for 15 minutes, myoglobinuria and elevation of CPK level were observed. ⋯ Diagnosis of Duchenne muscular dystrophy was first established after the development of malignant hyperpyrexia in the present case as well as in previously reported cases. Determination of serum CPK is very important before general anaesthesia.
