Open drop ether anaesthesis for Caesarean section: a review of 420 cases in Nepal

Abstract

Anaesthesia for Caesarean sections performed during 1982-83 at the Women's Hospital in Kathmandu, Nepal is reviewed, In a twelve-month period 535 Caesarean sections were performed, representing 7.36 per cent of 7,263 deliveries. Many pregnant women in Nepal do not have antenatal care and the mean haemoglobin of these mothers was 86g·L-1. In the absence of an on-call anaesthetist for obstetrics, more than 90 per cent of the anaesthetics were given by junior obstetric residents, using open drop diethyl ether without endotracheal intubation. Eleven patients developed postoperative chest infection; in none of these was there any suggestion of inhalation of gastric contents and all recovered uneventfully. Of the 18 maternal deaths in the 7, 263 delivereies during this period, one occurred during Caesarean section. This was due to uncontrollable haemorrhage and was not attributable to the anaesthetic. For poor risk patients, and in unskilled hands, diethyl ether remains a remarkably safe anaesthetic. © 1986 Canadian Anesthesiologists.
