Extradural analgesia in labour when the breech presents.

A retrospective study was made of the course and outcome of labour in 226 patients in whom a singleton fetus presented by the breech. Patients with macerated stillbirths or who were delivered before the 28th week of gestation had been excluded. Of the 226 patients, 101 received extradural analgesia, 79 received parenteral analgesia and 46 underwent elective Caesarean section. There was no difference in the incidence of breech extraction or emergency Caesarean section in the first two groups of patients. The length of both first and second stages of labour in multiparae was prolonged in the extradural group, but not markedly so. The Apgar scores of the infants delivered vaginally were not significantly different at one minute in both groups but the five minute Apgar score in the infants of primiparae was significantly higher in the extradural group. The Apgar score at one minute in the group delivered by emergency Caesarean section was significantly lower after extradural block but the difference was not significant at five minutes. This study suggests that the management and outcome of labour when the breech presents is not adversely affected by the provision of extradural analgesia.
