Neonatal jaundice: update on phototherapy management.

Phototherapy is now the standard form of treatment for infants with neonatal hyperbilirubinaemia. Though gradual in its effect, it finally produces a prolonged reduction in bilirubin values; retreatment with phototherapy is relatively rare. Factors that affect efficacy of phototherapy are: initial bilirubin level, birth weight, gestational age, postnatal age, aetiology of jaundice and light intensity and spectral emission. Phototherapy has now been demonstrated to be highly effective and safe; with simple precautions, no untoward side-effects will occur. The guidelines for commencement, monitoring and cessation of phototherapy are provided.
