AbstractHyperbilirubinemia is one of the most common problems encountered in term newborns. Historically, management guidelines were derived from studies on bilirubin toxicity in infants with hemolytic disease. More recent recommendations support the use of less intensive therapy in healthy term newborns with jaundice. Phototherapy should be instituted when the total serum bilirubin level is at or above 15 mg per dL (257 micromol per L) in infants 25 to 48 hours old, 18 mg per dL (308 micromol per L) in infants 49 to 72 hours old, and 20 mg per dL (342 micromol per L) in infants older than 72 hours. Few term newborns with hyperbilirubinemia have serious underlying pathology. Jaundice is considered pathologic if it presents within the first 24 hours after birth, the total serum bilirubin level rises by more than 5 mg per dL (86 micromol per L) per day or is higher than 17 mg per dL (290 micromol per L), or an infant has signs and symptoms suggestive of serious illness. The management goals are to exclude pathologic causes of hyperbilirubinemia and initiate treatment to prevent bilirubin neurotoxicity.
