There is no so-called unified and fast way to reduce infant jaundice, generally speaking, infant jaundice is divided into two cases, physiological jaundice does not need to be treated, pathological jaundice can be reduced through the light, drugs, blood exchange and other methods of jaundice, but it needs to be carried out under the guidance of a doctor. 1. Physiological jaundice: physiological jaundice in newborns is a normal physiological phenomenon. Generally speaking, jaundice of full-term babies appears 2~3 days after birth, reaches the peak in 4~5 days and subsides in 7~10 days. In this case, bilirubin level can be observed dynamically and there is no need for special treatment if there is no obvious increase in bilirubin level. 2. Pathological jaundice: it is also called pathological neonatal hyperbilirubinemia, which often appears within 24 hours after birth, lasts for a long time, and is characterized by recurrent episodes after subsiding. Jaundice can be quickly eliminated through blue light phototherapy, medication to alkalize the blood, and blood exchange under the guidance of a doctor. Pathological neonatal jaundice can be treated by blue light irradiation to promote the conversion of bilirubin to bound bilirubin in the newborn’s skin, as well as supplemental albumin, alkalinization of the blood, and promotion of bilirubin through blood exchange therapy if necessary. It should be noted that infants should be breastfed as early as possible after birth to promote the elimination of fetal stool. Failure to do so may result in increased enterohepatic circulation of bilirubin, leading to increased jaundice. Parents are advised to monitor their baby’s bilirubin level regularly. If the bilirubin level increases rapidly, or if the level is high, prompt medical attention should be sought. Follow medical advice for treatment.
