Hypoglycemia in the newborn.

ABSTRACT

Since a universal definition for hypoglycemia is lacking, an operational threshold for initiating therapy has been defined. Hypoglycemia is encountered in a variety of neonatal conditions including prematurity, growth retardation and maternal diabetes. Since hypoglycemia may be asymptomatic, routine screening for this condition in certain high risk situations is recommended. Supervised breast-feeding may be a 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/m should be investigated for refractory causes of hypoglycemia. Hypoglycemia has been linked to poor neuro-developmental outcome and hence aggressive screening and treatment is recommended.
