Subcutaneous use of a fast-acting insulin analog: an alternative treatment for pediatric patients with diabetic ketoacidosis.
OBJECTIVE
To look for technical simplification and economic efficiency in the treatment of pediatric diabetic ketoacidosis (DKA) with subcutaneous use of the fast-acting insulin analog (lispro) and compare its use with regular intravenous insulin treatment.


METHODS
In this controlled clinical trial from June 2001 to June 2003, we randomized 60 episodes of DKA with a blood glucose level > or = 16.6 mmol/l (300 mg/dl), venous pH <7.3 and/or bicarbonate <15 mmol/l, or ketonuria greater than + +. Of the 60 episodes, 30 were treated with subcutaneous lispro (0.15 units/kg) given every 2 h (lispro group) and the other 30 cases received continuous intravenous regular insulin (0.1 unit x kg(-1) x h(-1); CIRI group). Volume deficit was repaired with 10-ml/kg aliquots of 0.9% sodium chloride. Laboratory monitoring included hourly bedside capillary glucose, venous blood gas, beta-hydroxybutyrate, and electrolytes. Plasma blood glucose levels were measured on admission, 2 h after admission, when capillary blood glucose reached < or = 13.8 mmol/l (250 mg/dl), and 6, 12, and 24 h thereafter.


RESULTS
Capillary glucose levels decreased by 2.9 and 2.6 mmol x l(-1) x h(-1) in the lispro and CIRI groups, respectively, but blood glucose fluctuated at different time intervals. In the CIRI group, metabolic acidosis and ketosis resolved in the first 6-h period after capillary glucose reached 13.8 mmol/l, whereas in the lispro group, they resolved in the next 6-h interval; however, both groups met DKA recovery criteria without complications.


CONCLUSIONS
DKA treatment with a subcutaneous fast-acting insulin analog represents a cost-effective and technically simplified procedure that precludes intensive care unit admission.
