Most newborns will develop jaundice after birth. If the jaundice value is higher than the physiological range, we need to find the cause of the high jaundice value and actively give treatment to reduce the jaundice, too high bilirubin may affect the baby’s nervous system, combined with bilirubin encephalopathy, and in serious cases, it may leave sequelae that bring lifelong damage to the baby. There are many causes of high jaundice in newborns, such as neonatal hemolytic disease, infection, asphyxia and hypoxia, inadequate feeding, cranial hematoma, etc. It is necessary for the doctor to determine and treat the cause after examination, and only when the cause is removed can the jaundice subside better. The main treatment to reduce jaundice is phototherapy, which can reduce the jaundice of the baby. If the jaundice value is particularly high, bilirubin encephalopathy may occur, and blood exchange treatment may be required, which can reduce the bilirubin value relatively quickly. Medications need to be applied under the guidance of a doctor, such as gardenia jasminoides, but they may have certain side effects. Care is also important to ensure that the baby is fed adequately to avoid aggravating the jaundice due to insufficient feeding. So when your baby has high jaundice, you need to take your baby to the hospital in time to clarify the cause of the jaundice and give treatment to address the cause and reduce the yellowing, to avoid the jaundice level is too high to affect the baby’s nervous system.
