In phototherapy, blue fluorescent lights are used in the treatment of neonatal jaundice, a disorder in which the skin and whites of the eyes become yellow due to high levels of the pigment bilirubin in the blood. In order to maximize exposure, your baby will be undressed and placed under the lights in an incubator to keep him or her warm. You will be allowed to take your baby out of the incubator for feeding, but otherwise he or she will continue phototherapy until blood tests show that bilirubin levels are normal. In most cases, treatment is needed for a couple of days.
