Podcast 632: Neonatal Jaundice  

Contributor: Jared Scott, MD

Educational Pearls:

  • Bilirubin is natural breakdown product of red blood cells but can be neurotoxic if levels become too high
  • Fetal red blood cells are fragile and break down easier, leading to higher bilirubin levels in neonates¬†
  • Immature livers and increased intestinal absorption from sterile bowels also contribute to elevated levels and jaundice in all neonates
  • Other risk factors for neonatal jaundice include: temperature instability, poor feeding, hypoxia at birth, and being of East Asian descent
  • Neonatal bilirubin levels are referenced to time since birth using a nomogram to determine the need for light therapy (or exchange transfusion)
