Patient's question:
Baby started showing jaundice on the 3rd day of birth and now it has been 18 days, but the jaundice has not subsided yet. Urination and defecation are normal, often waking up during sleep, frequently hiccuping, and breastfeeding is normal. The baby started showing jaundice on the 3rd day of birth and began feeding infant glucose powder, and on the 7th day, they were given Yinzhihuang oral liquid.Doctor's answer:
Neonatal jaundice is the occurrence of yellow discoloration of the skin, sclera, and mucous membranes during the neonatal period, also known as neonatal hyperbilirubinemia. Its etiology is specific and complex, and severe cases can lead to bilirubin encephalopathy (kernicterus), often resulting in death and severe sequelae. Neonatal jaundice is generally divided into two major categories: physiological jaundice and pathological jaundice. Physiological jaundice is a normal physiological phenomenon. Due to the metabolic characteristics of bilirubin in newborns, approximately 60% of full-term infants and over 80% of preterm infants may develop jaundice 3-5 days after birth, but they are generally in good condition. In full-term infants, jaundice typically resolves within 14 days, while in preterm infants, it may persist for up to 3-4 weeks before completely subsiding.
