Phototherapy is the most common treatment for reducing high bilirubin levels that cause jaundice in a newborn.
In the standard form of phototherapy, your baby lies in a bassinet or enclosed plastic crib (incubator) and is exposed to a type of fluorescent light that is absorbed by your baby's skin. During this process, the bilirubin in the baby's body is changed into another form that can be more easily excreted in the stool and urine.
A baby with jaundice may need to stay under a phototherapy light for several days. Phototherapy doesn't damage a baby's skin.
During this type of phototherapy:
The baby is undressed so that as much of the skin as possible is exposed to the light.
The baby's eyes are covered to protect the nerve layer at the back of the eye (retina) from the bright light.
Feeding should continue on a regular schedule. There is no need to stop breast-feeding.
The bilirubin level is measured at least once a day.
Phototherapy helps to:
Increase vitamin D production
Ramp up bacteria-fighting systems in the skin
Phototherapy is used for eczema that is all over the body (widespread) or for localized eczema (such as hands and feet) that has not gotten better with topical treatments.
About 70% of people with eczema get better with phototherapy. Some people find that phototherapy puts their eczema in a “remittive” or “quiet” state long past the end of the treatment.
