Neonatal jaundice of 17.5mg/ml at 8 days exceeds the normal value, which should be pathologic jaundice, more serious, and may cause serious sequelae if not treated in time. Neonatal jaundice is called neonatal hyperbilirubinemia, which is caused by the accumulation of bilirubin in the body, resulting in yellowing of the skin or other organs, and is a common clinical problem in newborns. When the bilirubin of the newborn exceeds 5~7mg/ml, the symptoms of yellowing of the skin and sclera will appear and last for a long period of time, which should be considered as pathologic jaundice and the symptoms are more serious and need to be treated in time. Pathologic jaundice may cause hyperbilirubin encephalopathy, which needs timely treatment. The main treatments for neonatal pathological jaundice include light therapy, medication and other treatments, which should be carried out under the guidance of a doctor, paying attention to appropriate light exposure, keeping warm, observing the skin condition of the newborn, and consulting the doctor in time for any abnormality.
