The use of continuous insulin infusion for the peripartum management of pregnant diabetic women.

Sixteen pregnant diabetic patients near term were maintained on a regimen of continuous insulin infusion during the peripartum period. Blood glucose remained in the range of 75 to 150 mg. per deciliter, with insulin infusion rates between 0.25 and 2.00 U. per hour. Following delivery the infusion was continued through the first postpartum day or until oral intake was tolerated and subcutaneous long-acting insulin could be given. Sliding scale regimens were unnecessary; insulin dosage for discharge was easily determined; and the metabolic care of these patients was greatly simplified. Neonatal hypoglycemia in the 17 infants delivered of these diabetic patients was not entirely eliminated despite euglycemia in the mothers.
