Newborn babies with high jaundice can continue to test the bilirubin level in the baby’s body, if the bilirubin level in the baby’s body increases at a slower rate, then continue to observe, if the bilirubin level in the baby’s body increases too fast, then treatment is needed. Newborn babies with high jaundice, if the baby’s bilirubin level increases less than 5mg/dl per day or less than 0.5mg/dl per hour, then it is physiological jaundice, continue to observe and generally do not need to intervene too much. If the baby’s bilirubin level increases more than 5mg/dl per day or 0.5mg/dl per hour, then it is considered pathological jaundice, and you need to consult a doctor in time to identify the cause of jaundice and give targeted treatment. Common treatments include blue light irradiation, which converts unconjugated bilirubin into water-soluble isomers, which are then excreted through bile and urine; and transfusion of albumin, immunoglobulin, or the use of plasma exchange for treatment. If a newborn baby has high jaundice, it is recommended that he or she seek medical attention and follow the doctor’s instructions.
