The risk of jaundice to the baby depends mainly on the degree of jaundice, hyperbilirubinemia within 5-6 days after birth is the most dangerous for the baby. Once the total bilirubin exceeds 20 mg it may cause bilirubin encephalopathy, which will be lifelong for the baby and can leave various degrees of neurological sequelae, such as cerebral palsy, mental retardation, epilepsy, tardive dyskinesia, etc. Therefore, special attention should be paid to the monitoring of jaundice in the first 5 days after birth, especially if the jaundice appears within 24 hours after birth, and if it increases rapidly to 15 mg or more, it is important to cooperate with the doctor for active treatment to avoid the occurrence of bilirubin encephalopathy.
