title: Uterine rupture in pregnancy reviewed.
abstract: Uterine rupture is associated with maternal and fetal mortality and morbidity. In developed countries there have been many recent advances in the management of labour. This study, therefore, reviewed this Hospital's experience of uterine rupture in the decade 1982 to 1991. Excluding cases of asymptomatic scar dehiscence, there were 15 cases of uterine rupture in 65,488 deliveries, giving an overall incidence of 1 in 4,366. There was no case of rupture in 21,998 primigravidas. Of the 15 cases, only two occurred in 39,529 multigravidas without a previous uterine scar (1 in 19,765), and 13 cases occurred in the 3,961 multigravidas with a previous caesarean section scar (1 in 304). Twelve of the 13 ruptures after caesarean section occurred in the delivery immediately after the section. There were no maternal deaths but five (33%) patients required a hysterectomy. Three of the five perinatal deaths were attributable to the rupture. Ten of the 15 patients had labour induced, and a total of 13 patients received an oxytocic agent. Of the 15 cases, 8 were diagnosed during labour and 7 postpartum. Compared with earlier reports from Dublin, the incidence of uterine rupture was low due to a decrease in the number of ruptures associated with trauma or obstetric manipulation. The main associated feature was previous caesarean section. This review highlights the risk of uterine rupture when an oxytocic agent is administered to a multigravid patient with a previous caesarean section scar.
