Management of Hyperbilirubinemia in Newborns

Initial Assessment

The American Academy of Pediatrics recommends plotting the bilirubin level on the hour-specific risk nomogram (Bhutani nomogram) to assess the risk of severe hyperbilirubinemia, with a level of 12.8 mg/dL at 8 hours falling in the high-risk zone 2
Jaundice appearing within the first 24 hours is considered pathologic until proven otherwise and requires immediate investigation, according to the American Academy of Pediatrics 1
Obtaining total and direct bilirubin levels is necessary to determine if hyperbilirubinemia is predominantly unconjugated, as recommended by the American Academy of Pediatrics 3
Assessing for risk factors for severe hyperbilirubinemia, including blood type incompatibility, G6PD deficiency, and gestational age, is crucial in newborns with hyperbilirubinemia, as stated by the American Academy of Pediatrics 2

A complete blood count with differential and reticulocyte count should be performed to assess for hemolysis in newborns with hyperbilirubinemia, as recommended by the American Academy of Pediatrics 4
Blood type and Rh status of mother and infant should be determined to assess for blood type incompatibility, according to the American Academy of Pediatrics 5
Direct antibody test (Coombs) should be performed to assess for blood type incompatibility, as recommended by the American Academy of Pediatrics 5, 2
G6PD screening should be performed, especially if there is a family history or appropriate ethnic background, as stated by the American Academy of Pediatrics 2

Intensive phototherapy should be initiated immediately in newborns with high-risk hyperbilirubinemia, as recommended by the American Academy of Pediatrics 6, 4
Special blue light in the 430-490 nm spectrum with irradiance of ≥30 μW/cm²/nm should be used for phototherapy, according to the American Academy of Pediatrics 4
Breastfeeding should be supported and optimized with 8-12 feedings per day, as recommended by the American Academy of Pediatrics 5, 4

Total serum bilirubin (TSB) measurement should be repeated within 2-3 hours to assess response to phototherapy, as recommended by the American Academy of Pediatrics 4
Monitoring for signs of acute bilirubin encephalopathy, such as altered mental status, abnormal muscle tone, and high-pitched cry, is crucial in newborns undergoing phototherapy, according to the American Academy of Pediatrics 4
A decline of 0.5-1 mg/dL per hour in the first 4-8 hours of intensive phototherapy is expected, as stated by the American Academy of Pediatrics 4

Phototherapy should be continued until bilirubin levels fall below treatment threshold, typically 13-14 mg/dL, as recommended by the American Academy of Pediatrics 6, 4
After discontinuing phototherapy, a follow-up bilirubin measurement should be obtained within 24 hours, according to the American Academy of Pediatrics 6, 4

Visual assessment of jaundice alone is not reliable, and TSB measurements should always be obtained, as recommended by the American Academy of Pediatrics 6, 4
Delaying treatment while waiting for all laboratory results is not recommended if bilirubin level is significantly elevated, according to the American Academy of Pediatrics 1, 2
