Jaundice is when the skin and the whites
of the eyes (sclera) are yellow because of increased amounts of the pigment
called bilirubin in the body. Bilirubin is produced by normal breakdown
of red blood cells. Bilirubin accumulates if the liver doesn't excrete
it into the intestines at a normal rate.
There are 3 types of Jaundice:
Physiological Jaundice occurs in more than 50% of babies. Immaturity
of the liver leads to a slower processing of bilirubin. The jaundice
first appears at 2-4 days of age. It usually disappears by 1-2 weeks
of age and the levels reached are harmless.
Breast-Milk Jaundice occurs in 1% to 2% of breast-fed babies.
A special enzyme in the mother's milk causes it. This enzyme increases
the resorbence of bilirubin from the intestine. This type of jaundice
starts at 4-7 days and may last from 3-10 weeks.
Blood Group Incompatibility. If a mother and baby have different
types of blood, sometimes the mother produces antibodies that destroy
the newborn's red blood cells. This causes a sudden build up of bilirubin
in the baby's blood. This type of jaundice usually begins during the
first 25 hours of life. Rh (blood type factor) problems formerly caused
the most severe form of jaundice but are now preventable with an injection
of Rhogam to the mother within 72 hours after delivery. This prevents
her from forming the antibodies that might hurt future babies.
High levels of bilirubin (above 20) can cause deafness, cerebral palsy,
or brain damage in some babies. High levels usually occur with blood-type
problems but can occur with the other types of jaundice.
Treatment for high bilirubin levels is called Phototherapy (blue
lights). These lights help break down the bilirubin in the skin. In rare
cases where the level is dangerous, an exchange transfusion may be used.
This is done by taking out old blood while giving the baby new blood by
means of a blood transfusion. It's like "washing" the bilirubin
out.
Most of the time breast-milk jaundice can be prevented by frequent
feedings.
Nurse the baby every 1½ to 2½ hours. Since bilirubin is carried
out of the body in the stools, passing frequent bowel movements are
helpful.
If your baby sleeps more than 5 hours at night, wake him for feedings.
If the level does not come down with frequent feedings alternating
each breast-feeding with formula feedings for 2-3 days can reduce it.
Supplementing with glucose water is not as helpful as formula for moving
the bilirubin out of the body.
Whenever you miss nursing, be sure to use a breast pump to keep your
milk supply up.
Breast-feeding should never be permanently discontinued
because of breast-milk jaundice.
Once the jaundice clears, you can return to full breast-feeding. The
jaundice will not come back.
Newborns leave the hospital 48 hours after birth in the United States.
Parents have the responsibility of closely observing the degree of jaundice
in their newborn. The amount of yellowness is best judged by viewing your
baby unclothed in natural light.
Should you suspect jaundice in your newborn, contact your pediatrician.
