title: A ten-year review of uterine rupture in modern obstetric practice.
abstract: The aim of this paper is to determine the antecedent factors, clinical presentation, complications and management of uterine rupture in the context of modern obstetric practice in Singapore. We conducted a retrospective study of 26 proven cases of uterine rupture in Kandang Kerbau Hospital, Singapore between January 1983 to December 1992. These cases were analysed with regards to their past history, clinical presentation, complications, management and outcome. The incidence of uterine rupture was 1 in 6331 deliveries. The ratio of cases with scarred uteri against those with unscarred uteri was 3:1. The commonest antecedent factor was previous lower segment caesarean section for the scarred group and cephalo-pelvic disproportion in the unscarred group. Overall, 46.2% of the patients had augmentation with oxytocin. The major clinical presentations were abnormal cardiotocogram (25%) and blood-stained amniotic fluid (20%) in the scarred group, and postpartum haemorrhage (50%) and shock (33%) in the unscarred group. Repair of the uterus with or without tubal ligation was performed in 95% of the patients with scarred uteri, whereas 67% of the patients with unscarred uteri underwent total abdominal hysterectomy with or without salpingo-oophorectomy. There was 1 (3.8%) maternal death. Maternal morbidity included bladder injuries, broad ligament haematoma, disseminated intravascular coagulation and gastrointestinal bleeding. The overall incidence of fetal loss was 7.4%. When compared to a previous study on uterine rupture in the same hospital, there was an improvement in obstetric performance.
