What are the four bilirubin risk zones in the Bhutani nomogram?

The four zones are: Low risk (below 40th percentile), Low-Intermediate risk (40th-75th percentile), High-Intermediate risk (75th-95th percentile), and High risk (above 95th percentile). Higher zones indicate increased need for phototherapy.

When should bilirubin be measured in newborns?

Universal bilirubin screening is recommended at 24-72 hours of life before hospital discharge. The Bhutani nomogram then places the value in context of the infant age in hours to determine risk zone.

What additional factors affect jaundice risk beyond bilirubin level?

Risk factors for severe jaundice include gestational age below 38 weeks, previous sibling with jaundice, breastfeeding difficulties, East Asian race, exclusive breastfeeding, and bruising or cephalohematoma from delivery.
