OBJECTIVE: To compare the efficacy of insulin infusion of 0.05 Unit/kg/hour vs 0.1 Unit/kg/hour in the management of pediatric diabetic ketoacidosis (DKA).
DESIGN: Randomized, double-blind controlled clinical trial.
SUBJECT: Pediatric critical care division of a tertiary care hospital from October, 2014 to July, 2018.
PARTICIPANTS: Children aged 12 years or younger with a diagnosis of DKA. Children with septic shock and those who had received insulin before enrollment were excluded.
INTERVENTION: Low-dose (0.05 Unit/kg/hour) vs. Standard-dose (0.1 Unit/kg/hour) insulin infusion.
OUTCOME MEASURES: The primary endpoint was time for resolution of DKA (pH ≥7.3, bicarbonate ≥15 mEq/L, beta-hydroxybutyrate <1 mmol/L). Secondary outcomes were the rate of fall in blood glucose until 250 mg/dL or less and the rate of complications (hypokalemia, hypoglycemia, and cerebral edema).
RESULTS: Sixty patients were analyzed on an intention-to-treat basis (Low-dose group: n=30; Standard-dose group: n=30). Mean (SD) time taken for the resolution of ketoacidosis was similar in both groups [22 (12) vs 23 (18.5) hours; P=0.92]. The adjusted hazard ratio (95% CI) of the resolution of ketoacidosis was lower in the low-dose group [0.40 (0.19 to 0.85); P=0.017]. Mean (SD) rate of blood glucose decrease until 250 mg/dL or less reached [56 (41) vs 64 (65) mg/dL/hour; P=0.41] and time to achieve the target [4.2 (3.1) vs 4.8 (3.3) hours; P=0.44] were similar in both groups. Hypokalemia [30% vs 43.3%; P=0.28] and hypoglycemia [3.3% vs 13.3%; P=0.35] were lower in low-dose group. No child had cerebral edema, and no mortality occurred.
CONCLUSIONS: Time for resolution of ketoacidosis was similar in the low-dose and standard-dose insulin with a lower rate of therapy-related complications in the low-dose group. Hence, low-dose insulin infusion can be a safer approach in the management of pediatric DKA.
