Patient's question:
My baby was born on the 11th and was discharged from the hospital on the 16th. When I was discharged, the doctor said that my baby's jaundice was within the normal physiological range. But today, when I went for a check-up, my baby's forehead was 14.1mg, face was 15.3mg, and chest was 17.7mg. I want to ask, what is the normal value range for baby jaundice?Doctor's answer:
Physiological jaundice is caused by the metabolic characteristics of bilirubin in children. Approximately 50% to 60% of full-term infants and 80% of preterm infants develop physiological jaundice. Its characteristics are: (1) generally good condition; (2) jaundice appears 4–5 days after birth, with a peak at 4–5 days, lasting 5–7 days, and not exceeding 2 weeks at the latest; for preterm infants, jaundice appears after 3–5 days of birth, with a peak at 5–7 days, disappearing 7–9 days later, and may persist for up to 4 weeks; (3) serum bilirubin increases by 2 weeks daily; for preterm infants, it exceeds 4 weeks; (4) jaundice subsides and recurs; (5) serum conjugated bilirubin > 34 μmol/L (2 mg/dL).
