Questions
Is it true that once neonatal jaundice subsides, there is no possibility of developing kernicterus? Do we still need to perform a blood test for serum total bilirubin after jaundice resolves? Does a high level of serum total bilirubin manifest itself in the jaundice value?
Answer
Neonatal jaundice is a disease in the neonatal period where jaundice appears due to elevated blood bilirubin levels caused by abnormal bilirubin metabolism in the skin, mucous membranes, and sclera. This condition is mainly caused by neonatal hemolytic disease. Physiological jaundice appears 2-3 days after birth, reaches its peak at 4-6 days, and resolves within 7-10 days. Premature infants may have a longer duration, with only mild loss of appetite as a clinical symptom and no other treatment required. Once neonatal jaundice subsides, there is no possibility of developing kernicterus. A blood test for serum total bilirubin can help doctors assess the severity of jaundice and further determine whether treatment is needed. A high level of serum total bilirubin indicates an increased concentration of bilirubin in the blood, which also reflects an increase in the jaundice value.
