Overview
The mainstay of treatment of patients with neonatal jaundice is phototherapy, intravenous immunoglobulins and blood exchange.
Medical Therapy
- Phototherapy or blood transfusion are recommended by the American Academy of Pediatrics (AAP) for the treatment of neonatal jaundice.[1]
- It is recommended to treat the newborns with phototherapy or blood transfusion in order to decrease the risk of severe hyperbilirubinemia and kernicterus development.
Phototherapy
- Phototherapy is considered as the safest intervention approach used in treatment of neonatal jaundice.
- Phototherapy showed its efficacy in lowering the level of the total serum bilirubin in all patients with neonatal jaundice regardless the underlying cause.[2][3]
- Phototherapy also acts on preventing the rise of the bilirubin to the level of exchange transfusion threshold.[4]
- The total bilirubin level should be assessed every three hours after starting the phototherapy. The efficacy of phototherapy is assessed by the drop of the bilirubin level which is the best indicator of the neonatal response to the phototherpay.[5]
- If the level of the bilirubin still high after initiating the phototherapy, blood transfusion is indicated and to be initiated.
Mechanism of phototherapy
- Phototherapy can lower the level of bilirubin in neonatal jaundice via the following mechanisms:[6][7]
- Isomerization of bilirubin to lumirubin which is more soluble[8]
- Isomerization of bilirubin isomers to less toxic isomers (ex. 4Z and 15E)
- Phototherapy converts bilirubin into soluble polar compounds by oxidation
- Different sources of the light required for phototherapy: [9]
- Home phototherapy
- Sunlight exposure
- Filtered sunlight
- Fluorescent tubes
- Halogen white light
- Blue LEDs
Adverse effects of phototherapy
- Although phototherapy is of a high safe margin, the following adverse effects are associated with phototherpay in some cases:
Exchange transfusions
- Blood transfusion is reserved for the patients who still have high level of bilirubin even after receiving treatment by phototherapy.[1]
