Why does phototherapy help jaundice




















Many infant warmers have integrated phototherapy due to the prevalence of jaundice in some babies with hypothermia. Regardless of whether a standard lamp or an infant warmer is used to administer phototherapy, the goal of phototherapy is to expose as much of the skin as possible to the light while protecting the eyes.

Bilirubin levels are measured on a regular basis until the jaundice is alleviated. Biliblankets are another effective means of treating jaundiced infants. Like infant warmers and phototherapy lamps, biliblankets administer therapeutic light to jaundiced babies. However, biliblankets differ from the other modes of phototherapy in the way the phototherapy is administered.

Biliblankets involve the use of a fiber optic cable that transmits therapeutic light that is produced by a portable light-emitting generator. The cable disperses the light to the infant through the use of a pad or blanket. Biliblankets are normally reserved for those cases of jaundice that are not severe and offer elements of convenience compared to more traditional modes of phototherapy. Your health care provider will prescribe the amount of time your baby will be on the biliblanket each day.

Most babies have phototherapy treatment for several days. Your baby's bilirubin level will be tested during treatment, usually by a small sample of blood taken from the baby's heel. These tests will determine when normal levels of bilirubin are reached and phototherapy is no longer needed. Skip Navigation UofMHealth. University of Michigan Health System C. Mott Children's Hospital. Mott Home Why Choose Us? Because the baby has an immature liver, bilirubin is processed slower. The jaundice first appears at 2 to 3 days of age.

It usually disappears by 1 to 2 weeks of age, and the levels of bilirubin are harmless. Breast-feeding jaundice: Breast-feeding jaundice may occur when your baby does not drink enough breast milk. The jaundice symptoms are similar to those of physiological jaundice, just more pronounced. The jaundice indicates a need for help with breast-feeding. It is caused by a special substance that some mothers produce in their milk. This substance causes your baby's intestine to absorb more bilirubin back into his body than normal.

This type of jaundice starts at 4 to 7 days of age. It may last 3 to 10 weeks. It is not harmful. Blood group incompatibility Rh or ABO problems : If a baby and mother have different blood types, sometimes the mother produces antibodies that destroy the newborn's red blood cells.

No, although some people who are around blue lights for prolonged periods will feel nauseated. Yellow plastic placed on the outside of the isolette may mitigate this effect.

There are no specific guidelines for when to discontinue phototherapy. Evidence of hemolysis and age of the infant will impact the duration. In some cases, phototherapy will only be needed for 24 hours or less, in some cases, it may be required for 5 to 7 days. In general, serum bilirubin levels should show a significant decrease before the lights are turned off.

Physical examination for jaundice is not helpful once treatment has started as the yellow color of the skin is temporarily "bleached" by the phototherapy.

The effectiveness of phototherapy is determined largely by the distance between the lamps and the infant, so phototherapy can easily be intensified by bringing the lamps closer to the infant. Because a closed isolette does not allow the lamps to be moved in close, if there is a concern about the effectiveness of phototherapy, an isolette should not be used.

With the infant in an open bassinet, it is possible to bring the lamps to within 10 cm of the infant. Specifically, they are more portable than phototherapy lamps and infant warmers and biliblankets allow a jaundiced infant to be treated with phototherapy at home. Sign in. Log into your account.
