Intrapartum management of insulin-dependent diabetes mellitus (IDDM) gestants. A comparative study of constant intravenous insulin infusion and continuous subcutaneous insulin infusion pump (CSIIP).

Two groups of insulin-dependent diabetes mellitus (IDDM) parturients were managed according to different intrapartum protocols and compared with a control group of normal women in labor. Thirty-seven patients received conventional intensified insulin therapy during pregnancy and intravenous continuous insulin infusion during labor. Twenty-eight women were managed by continuous subcutaneous insulin infusion pump (CSIIP) throughout gestation and this therapeutic approach was continued during labor. When the two glucose control techniques were compared, CSIIP was superior to achieving and maintaining intrapartum optimal metabolic control, reducing significantly the incidence of acute fetal distress, thus lowering the cesarean section rate and neonatal hypoglycemia. Consequently we concur with the recommendation that firm prepartum as well as intrapartum diabetic control is mandatory for successful management of labor in IDDM patients.
