Neonatal physiologic jaundice results from simultaneous occurrence of the following two phenomena : • Bilirubin production is elevated because of increased breakdown of fetal erythrocytes. This is the result of the shortened lifespan of fetal erythrocytes and the higher erythrocyte mass in neonates.Neonatal hyperbilirubinemia, defined as a total serum bilirubin level above 5 mg per dL (86 μmol per L), is a frequently encountered problem.
Phototherapy is treatment with light. It is used in some cases of newborn jaundice to lower the bilirubin levels A blood transfusion, known as an exchange transfusion, may be recommended if your baby has particularly high levels of bilirubin Breastfeeding rates following the discharge of infants diagnosed with jaundice were not significantly different from those reported for the general population. Larger prospective studies in diverse populations are needed to determine the rates of early breastfeeding discontinuation in jaundiced infants.
