Acute bilirubin encephalopathy Bilirubin is toxic to cells of the brain.
Newborns should be examined within 24 to 72 hours of hospital discharge to assess for jaundice and general well-being.
Its effectiveness is related to the area exposed, radiant energy, and wavelength 400-500 nanometers.
It occurs because of physiological changes taking place during the transition from intrauterine to neonatal life.
Early damage to the brain can be reversible but if hyperbilirubinemia is pronounced or prolonged then it can lead to cerebral palsy, sensorineural hearing loss or cognitive impairment.
