The timing of delivery in diabetic pregnancy: a 10-year review.
The approach of term in the pregnancy of a diabetic woman is a time of anxiety for patient and physician alike. The impact of a conservative approach to the timing of delivery is outlined in this review of the clinical course and outcome of 276 pregnancies of diabetic women, delivered at the National Maternity Hospital, Dublin between 1981 and 1990. The mean gestation at delivery was 39 weeks, 229 patients (83%) delivered at or beyond 38 weeks and 112 patients (41%) delivered at or beyond 40 weeks. The overall induction of labour rate was 27% and the elective Caesarean section rate was 19%. Sixty seven percent of patients achieved a normal delivery, the forceps rate was 5%, and 28% of patients were delivered by Caesarean section. There were 16 perinatal deaths in the series, with 7 due to lethal malformations. There were 5 deaths of normally formed infants occurring at or beyond 38 weeks' gestation. All of these 5 deaths had been preceded by clinically apparent polyhydramnios or macrosomia and recognized poor control. This study stresses the value of strict diabetic control in the management of diabetic pregnancy and highlights the significance of polyhydramnios and macrosomia as indicators of risk approaching term in diabetic pregnancy.
