Term newborns have a significantly higher glucose requirement than older children, and preterm infants have the highest needs of all. It is usual to start with a 10% dextrose solution at approximately 6 g/kg/d (4 mg/kg/min), and to increase this incrementally if there is no hyperglycemia. Continuous insulin infusions have been used as an effective treatment of hyperglycemia in preterm infants.
