Many babies have high bilirubin levels in the blood. Between 3-12 out of every 100,000 children develop very high levels (severe NH). Certain factors increase the risk of severe NH. Babies born early (premature) and babies with a different blood type from their mothers have a higher risk of severe NH.

We therefore sought to define bilirubin levels in a normal newborn population (gestational age: 35 weeks) in the first 96 hours after birth, and the avail-ability of TcB measurements made it possible to obtain such data.

If the bile ducts are obstructed, direct bilirubin will build up, escape from the liver, and end up in the blood. If the levels are high enough, some of it will appear in the urine. Only direct bilirubin appears in the urine. Increased direct bilirubin usually means that the biliary (liver secretion) ducts are obstructed.

In healthy full-term neonates, bilirubin can rise to peak levels of 5 to 13 mg/dL between the second and fi fth days of life before decreasing to normal levels between the fi fth and seventh days. This produces jaundice, a yellowish discoloration of the skin, eyes, and mucous membranes. Monitoring bilirubin concentration is

serum bilirubin (TSB) concentration greater than 340 μmol/L at any time during the first 28 days of life. (2) Critical hyperbilirubinemia is defined as a TSB concentration greater than 425 μmol/L. (2) High levels of bilirubin may lead to acute bilirubin encephalopathy defined as the clinical manifestation of bilirubin toxicity.

A report of dark urine or light stools should prompt a measurement of direct serum bilirubin. If the history (particularly the appearance of the urine and stool) and physical examination results are normal, continued observation is appropriate. If jaundice persists beyond 3 weeks, another measurement of total and direct serum bilirubin obtained.

• If breastfeeding is continued, bilirubin gradually decreases but may persist for 3-10 wk at lower levels. • If nursing is discontinued, the serum bilirubin level falls rapidly, reaching normal range within a few days. • Resumed breastfeeding seldom returns bilirubin to previously high levels.
