Patient's question:
Hello, doctor. My baby has for 40 days, and we have also used blue light therapy. We have bought a lot of herbal remedies for treating, but they haven't been very effective. What should we do? Urgent!Doctor's answer:
Neonatal jaundice is the yellowing of the skin, sclera, and mucous membranes that occurs during the neonatal period, also known as neonatal hyperbilirubinemia. Its etiology is specific and complex, and severe cases can lead to bilirubin encephalopathy (kernicterus), often resulting in death and severe sequelae. Neonatal jaundice is generally divided into two major categories: physiological jaundice and pathological jaundice. Physiological jaundice is a normal physiological phenomenon. Due to the metabolic characteristics of bilirubin in newborns, approximately 60% of full-term infants and over 80% of preterm infants may develop jaundice 3-5 days after birth, but they are generally in good condition. Full-term infants typically recover from jaundice within 14 days, while preterm infants may take up to 3-4 weeks to fully recover. Pathological jaundice, on the other hand, is abnormal and is generally associated with the following factors: ① bacterial infections and neonatal sepsis, as well as viral infections such as hepatitis A virus, hepatitis B virus, and cytomegalovirus; ② neonatal hemolytic disease; ③ congenital biliary atresia and biliary cysts; ④ breast milk jaundice, which typically appears 4-7 days after birth, peaks within 2-3 weeks, and the bilirubin level drops within 1-3 days after stopping breastfeeding. If there is no significant decrease after 3 days, breast milk jaundice can be ruled out; ⑤ other factors such as genetic diseases and drug-induced jaundice. Neonatal jaundice should be considered pathological if any of the following conditions are present: ① jaundice appearing early (within 24 hours after birth); ② severe jaundice or rapid progression; ③ prolonged duration of jaundice (more than 2 weeks for full-term infants, more than 4 weeks for preterm infants); ④ reappearance of jaundice after it has subsided. Pathological jaundice caused by any factor or etiology should be treated by identifying and addressing the underlying cause. This is particularly crucial for premature infants within the first week of life and those with severe hypoxia, acidosis, intracranial lesions, or severe infections, who must receive prompt and aggressive treatment to avoid adverse outcomes.
