Continuous insulin intravenous infusion therapy for VLBW infants.

Very low birth weight (VLBW) infants less than 1,000 g often experience hyperkalemia and hyperglycemia during the initial hospital course. Hyperkalemia has been noted in 44% to 50% of infants less than 800 g birth weight or less than 28 to 29 weeks' gestation. Hyperglycemia occurs 18 times more frequently in infants less than 1,000 g than in those weighing more than 2,000 g. Insulin has been used for VLBW infants less than 1,000 g to manage hyperkalemia, control hyperglycemia, and optimize parenteral nutrition. A protocol for using exogenous insulin therapy for VLBW infants is described.
