Pregnancy in the Diabetic Patient

Abstract

The clinical outcome of 141 consecutive diabetic pregnancies managed in the National Maternity Hospital between Jan. 1, 1979, and Oct. 31, 1982, is described. Patients with gestational diabetes were excluded. There were 12 spontaneous abortions, and the perinatal mortality in 129 viable pregnancies was 31/1000. The malformation rate was 6.4%. Significant perinatal morbidity occurred in 20% of infants. The incidence of cesarean section was 20%. Spontaneous labor after 38 wk occurred in 30% because there was a deliberate policy to allow all uncomplicated pregnancies to continue to term. This policy had benefits for the infant as well as the mother because there was a notable reduction in neonatal morbidity. Possible explanations of high cesarean section rates in other centers are discussed.
