Depending on the rate at which the bilirubin level rises, a newborn's risk of developing significant hyperbilirubinemia can be classified as low, intermediate, or high (Figure 2).22 With the assumption that the bilirubin level will continue to rise at the same rate, the physician can predict the potential further progression of the rise and calculate the number of days that the infant may be at risk for bilirubin toxicity. The best timing for this depends on bilirubin level and risk factors. An exception is undersecretion of bilirubin due to metabolic factors (eg, Crigler-Najjar syndrome, hypothyroidism, drugs), which may take 2 to 3 days to become evident. If it looks yellow instead of pale, there may be jaundice. If we combine this information with your protected Bilirubin is processed and removed by the liver. Features of pathologic jaundice include the appearance of jaundice within 24 hours after birth, a rapidly rising total serum bilirubin concentration (increase of more than 5 mg per dL per day), and a total serum bilirubin level higher than 17 mg per dL in a full-term newborn.3,5 Other features of concern include prolonged jaundice, evidence of underlying illness, and elevation of the serum conjugated bilirubin level to greater than 2 mg per dL or more than 20 percent of the total serum bilirubin concentration.

Shorter neonatal red blood cell life span increases bilirubin production, deficient conjugation due to the deficiency of uridine diphosphate-glucuronosyltransferase (UGT) decreases clearance, and low bacterial levels in the intestine combined with increased hydrolysis of conjugated bilirubin increase enterohepatic circulation. Newborns also have more red cells than older children and adults, and those brand-new red cells dont last as long as red cells made as babies grow older. Management of hyperbilirubinemia in the newborn infant 35 or more weeks of gestation. BONUS! If a baby has severe jaundice, there's a risk of bilirubin passing into the brain, a condition called acute bilirubin encephalopathy. Use OR to account for alternate terms Only unconjugated hyperbilirubinemia can cause kernicterus, so if conjugated bilirubin is elevated, the level of unconjugated rather than total bilirubin is used to determine the need for exchange transfusion. In the presence of hemolytic disease, severe anemia, or a rapid rise in the total serum bilirubin level (greater than 1 mg per dL per hour in less than six hours), exchange transfusion is the recommended treatment.
