Management of hyperglycemia in the neonatal unit: A practical approach to diagnosis and management

Abstract

Neonatal hyperglycemia is a common metabolic disorder seen in very low birth weight (VLBW) and critically ill newborns. Hyperglycemia is a recognized cause for mortality and morbidity in the neonatal period. Incidence in preterm infants is around 45%–80%. The mechanism of increased risk of hyperglycemia in preterm infants is not well understood, but different possible mechanisms have been reported. Plasma glucose values more than 180–200 mg/dl (10–11.1 mmol) are of concern as this can lead to complications. Hyperglycemia was found to predispose to severe intraventricular hemorrhage, retinopathy of prematurity, necrotizing enterocolitis, and increased mortality. It is important to recognize and manage this condition early to avoid serious complications. Multiple etiologies with different management strategies are mentioned in the literature. Here, we discuss a complete understanding on practical management of hyperglycemia and we propose a simplified practical approach for the diagnosis and management of neonatal hyperglycemia.
