Over the years of medical practice, we have found that many people have misconceptions about neonatal jaundice, especially the older generation of grandparents, but even more so, mainly in the following areas: 1, jaundice is normal, it will get better on its own and does not require treatment. 2, jaundice is “yellow lock”, can be treated by “lock” (acupuncture) and eat “Chinese herbal medicine”. 3, jaundice is physiological, and eating breast milk related, after a period of time will be fine. 4, the newborn is too small, jaundice can not deal with it, wait for the full moon. Is this really true? Actually not. Neonatal jaundice can be divided into physiological and pathological, breast milk sex. Physiological jaundice is characterized by: ① good general condition; ② jaundice in full-term infants 2-3 days, 4-5 days to peak, 5-7 days to subside, the latest not more than 2 weeks; preterm infants jaundice more than 3-5 days after birth, 5-7 days to peak, 7-9 days to subside, the longest delay to 4 weeks; ③ daily jaundice index rise <5; ④ jaundice index full-term infants <12.9, preterm infants <15. but there are Data show that bilirubin encephalopathy can occur in small preterm infants with a jaundice index of <10. Pathological jaundice has the following characteristics: ① jaundice appears within 24 hours after birth; ② severe jaundice, jaundice index > 12.9 in term infants and > 15 in preterm infants, or rising more than 5 per day; ③ jaundice lasts for a long time (> 2 weeks in term infants and > 4 weeks in preterm infants); ④ jaundice recedes and reappears; ⑤ direct bilirubin > 2. We should actively search for the cause of pathological jaundice and actively treat it. Breastfeeding jaundice, the incidence of about 1% of breastfed infants. It is characterized by jaundice mostly appearing 3 to 8 days after birth, peaking at 1 to 3 weeks and subsiding at 6 to 12 weeks, stopping breastfeeding for 3 to 5 days, if the jaundice is significantly reduced or subsides to help the diagnosis. Therefore, identification of the classification of jaundice and correction of misconceptions about jaundice are key to the diagnosis and treatment of jaundice.
