A glucose-controlled insulin infusion system for diabetic women during labour.

Abstract

A glucose-controlled insulin infusion system was used to control blood glucose concentration during labour or caesarean section in six insulin-dependent diabetics. The mean blood glucose concentration during the four hours of labour immediately before delivery was 4.6-5.2 mmol/1 (82.9-93.7 mg/100 ml). Feedback control of insulin delivery by blood glucose concentration should decrease the risk of postpartum hypoglycaemia in the infant and allow normal obstetric management for the insulin-dependent diabetic in labour.
