Background

  • Must distinguish between unconjugated and conjugated hyperbili
    • Conjugated is always pathologic

Risk Factors

  • Isoimmune hemolytic disease
  • G6PD deficiency
  • Asphyxia
  • Significant lethargy
  • Temperature instability
  • Sepsis
  • Acidosis

Work-Up

  • Tbil/Dbil
  • CBC (for hemolytic anemia)
  • Coombs or T&S (mom & baby)

DDx

Common

  • Physiologic
  • Breast Milk Jaundice
    • Due to substances in milk that inhibit glucuronyl transferase
    • May start as early as 3rd day, reaches peak by 3rd week of life
    • Unlikely to cause kernicterus
  • Breast-Feeding Jaundice (starvation jaundice)
    • Pt does not receive adequate oral intake
      • Results in reduced bowel movement/bilirubin excretion

Uncommon

  • Direct (conjugated, post- liver obstructive)
    • congenital biliary atresia
    • neuroblastoma
    • cholesterol cysts
  • Cellular
    • hepatitis
    • galactosemia
    • sepsis
    • TORCHS
    • tyrosinemia
    • alpha 1 antitrypsis deficiency
  • Indirect (unconjugated, pre-liver)

Treatment

  • Breast Milk Jaundice
    • Do not need to routinely d/c breast-feeding
    • Treat w/ phototherapy when necessary
  • Breast-Feeding Jaundice
    • Supplement with expressed breast milk or formula
  • Exchange transfusion
    • Consider if signs of bilirubin encephalopathy
      • Hypertonia, arching, retrocollis, opisthotonos

Phototherapy Guidelines
