ABSTRACT

Diabetic ketoacidosis (DKA) is the commonest hyperglycemic emergency in people with diabetes. Fluid and insulin, commonly via intravenous route, is the mainstay of treatment; however, other methods of insulin administration have been tried. In this study, we aimed at comparing the efficacy and safety of continuous subcutaneous insulin infusion (CSII) to intravenous (IV) insulin infusion protocol using a short acting insulin analogue, glulisine, in patients with mild to moderate DKA. This is a prospective randomized controlled trial including 30 patients with DKA randomly assigned to receive Glulisine insulin via CSII or IV infusion. Metabolic parameters were observed till resolution of DKA. Primary end point was assessment of the duration till resolution. Secondary end points included total length of hospitalization, amount of insulin used and the number of hypoglycemic events. There were no statistical differences in the mean duration of treatment until correction of DKA being 16.58 ± 3.68 hours for CSII group versus 14.60 ± 3.2 hours in the IV group, p=0.136. There was no mortality and no differences in the length of hospital stay, or the number of hypoglycemic events among treatment groups. However, the total amount of insulin administration until resolution of ketoacidosis was significantly higher, 61.50 ± 13.89 units, in CSII group compared to 46.60 ± 13.53 units in the IV group, p=0.009. We concluded that the use of CSII of glulisine insulin represented a safe and effective alternative to the use of IV glulisine in the management of patients with mild to moderate DKA.
