Neonatal jaundice value of 25mg/dL is more serious, parents are advised to take their children to the hospital for relevant examinations to find the cause of jaundice. Common causes of neonatal jaundice include hypoxia, infection, hemolytic disease of the newborn, congenital biliary atresia, etc. The cause of jaundice should be found and treated according to the cause. If the child has an infection, anti-infection treatment should be given. If there is hemolytic disease, blue light irradiation treatment should be given, and the use of albumin or immunoglobulin should be chosen according to the condition, and blood exchange treatment should be carried out if necessary. If the child has congenital biliary atresia, surgical treatment will be performed, and if necessary, a liver transplant will be performed. If neonatal jaundice is not actively treated, the unconjugated bilirubin in the serum will pass through the blood-brain barrier, causing dysfunction of the central nervous system, and even permanent damage, so parents should pay attention to neonatal jaundice, and active treatment.
