Low-Dose Intravenous Insulin Infusion Versus Subcutaneous Insulin Injection: A Controlled Comparative Study of Diabetic Ketoacidosis

Abstract

Fourteen paients, 5 to 17 years old, with 18 episodes of uncomplicated diabetic ketoacidosis were randomly allocated and studied prospectively. The study group received 0.1 units of insulin per kilogram of body weight per hour as a continuous intravenous infusion; the control group received insulin subcutaneously. In both groups, a gradual fall in serum glucose and ketone levels was achieved. Serum ketones persisted longer in the intravenous group. No complications were encountered. The study suggests that both regimens of insulin administration are equally effective, but a low-dose constant infusion may provide more simplified and controlled management than the standard subcutaneous regimen.
