Cerebral palsy is a common childhood disease, and there are many causes of cerebral palsy disease. Neonatal jaundice is also one of the causes of cerebral palsy, and neonatal jaundice is divided into pathological jaundice and physiological jaundice, so it is important to conduct relevant tests to determine the type of neonatal jaundice. Note to parents: Neonatal jaundice can bring about pediatric cerebral palsy. Why is it that neonatal jaundice may bring about pediatric cerebral palsy? 1, the etiology of jaundice: such as neonatal hemolytic disease, neonatal G6PD, neonatal spherocytosis, neonatal perinatal diseases, etc., can cause both hyperbilirubinemia and bilirubin encephalopathy, as well as anemia, hypoxia and hypoxic-ischemic encephalopathy. All these diseases and pathological changes can lead to fetal and neonatal brain damage and subsequently to pediatric cerebral palsy. 2. Bilirubin encephalopathy: If one is suffering from hyperbilirubinemia, bilirubin can damage certain nuclei of the central nervous system through the blood-brain barrier, causing bilirubin encephalopathy which leads to cerebral palsy. Neonatal jaundice is caused by high bilirubin in the body, so the normal value of neonatal jaundice is also measured by the bilirubin level. In general, the bilirubin level in normal human body is 1.7-17.1umol/L. If the bilirubin in the body exceeds this level, it can be called jaundice, and the normal value of jaundice in premature newborns does not exceed 3mg/dl. If the jaundice is physiological, it can gradually subside in two to three weeks, and the degree of jaundice is also light; while pathological jaundice can make the child cry and have a bad spirit.
