Hypoglycemia in the newborn.

Hypoglycemia in a neonate is defined as blood sugar value below 40 mg/dL. It is commonly associated with a variety of neonatal conditions like prematurity, intrauterine growth restriction and maternal diabetes. Screening for hypoglycemia in high-risk situations is recommended. Supervised breast-feeding may be an initial treatment option in asymptomatic hypoglycemia. However, symptomatic hypoglycemia should always be treated with a continuous infusion of parenteral dextrose. Neonates needing dextrose infusion rates above 12 mg/kg/min should be investigated for a definite cause of hypoglycemia. Hypoglycemia has been linked to poor neuro-developmental outcome, and hence aggressive screening and treatment is recommended.
