What level of bilirubin needs phototherapy?
Phototherapy should be instituted when the total serum bilirubin level is at or above 15 mg per dL (257 mol per L) in infants 25 to 48 hours old, 18 mg per dL (308 mol per L) in infants 49 to 72 hours old, and 20 mg per dL (342 mol per L) in infants older than 72 hours.
How quickly does bilirubin drop with phototherapy?
Once your baby’s bilirubin levels have stabilised or started to fall, they’ll be checked every 6 to 12 hours. Phototherapy will be stopped when the bilirubin level falls to a safe level, which usually takes a day or two.
How long do jaundice babies need phototherapy?

Can you breastfeed a baby with jaundice?
Usually. Most newborns with jaundice can continue breastfeeding. More frequent breastfeeding can improve the mother’s milk supply and, in turn, improve caloric intake and hydration of the infant, thus reducing the elevated bilirubin.
How does breast milk affect neonatal jaundice?
Breast milk jaundice most often occurs in the second or later weeks of life and can continue for several weeks. While the exact mechanism leading to breast milk jaundice is unknown, it is believed that substances in the mother’s milk inhibit the ability of the infant’s liver to process bilirubin.
Does phototherapy darken baby’s skin?
With exposure to phototherapy lamps, these infants develop a dark, gray-brown discoloration of skin, urine, and serum. Although the exact etiology is not understood, this effect is thought to be the result of an accumulation of porphyrins and other metabolites.
What are normal bilirubin levels in newborns?
In a newborn, higher bilirubin is normal due to the stress of birth. Normal indirect bilirubin would be under 5.2 mg/dL within the first 24 hours of birth. But many newborns have some kind of jaundice and bilirubin levels that rise above 5 mg/dL within the first few days after birth.
Is the baby at risk for severe hyperbilirubinemia?
