Prolonged Jaundice in Newborn

Abstract

Prolonged jaundice is defined as a serum bilirubin level higher than 85 μmol/L (5 mg/dl), which persists at postnatal 14 days in term infants and 21 days following the birth in preterm infants. It affects 2–15% of all newborns and 40% of breastfed infants. Although underlying cause can not be found in the majority of prolonged jaundice cases, this may also be the first sign of a serious causative pathology. Tests performed to determine the underlying cause and failure to determine the etiology cause anxiety for both families and physicians. The most important point is to determine whether prolonged jaundice is of a benign cause or is due to a substantial disease. For this reason, health care providers should not take unnecessary tests in normal infants, but should also recognize infants with a causative pathology. Neonatal jaundice still maintains its importance in neonatal clinical practice, since early diagnosis and treatment is feasible.
