Phototherapy is the most common treatment for reducing high
bilirubin levels that cause
jaundice in a newborn.
In the standard form of phototherapy, the baby is placed in an
enclosed plastic crib (incubator) and is exposed to a type of fluorescent light
that is absorbed by the 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 usually does not 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.
- An incubator with a heat
control is used to maintain the correct body temperature.
- 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.
Potential problems that may occur during this standard form of
phototherapy include:
- Burns similar to sunburn (from the intense
light), skin rashes, and tanning.
- Damage to the nerve layer at the
back of the eye (retina), if the eyes are not properly
protected.
- Dehydration, if the infant does not
receive adequate fluids when feeding.
- Difficulty in maintaining the
proper body temperature.
Another type of phototherapy is a fiber-optic blanket or a band.
These devices wrap around a baby and can be used at home. Although fiber-optic
phototherapy has been shown to reduce bilirubin levels, it takes longer than
conventional phototherapy done in a hospital setting. It can be a good
alternative for babies with mild jaundice who are otherwise healthy.1
If your baby is being treated at home for jaundice, it is important
that you understand how to use all the equipment. Ask your health professional
for help if you have questions or concerns. A home health nurse may visit to
make sure all is going well. The amount of bilirubin in your baby's blood may
need to be measured daily.
