The jaundice value is the bilirubin concentration. A neonatal bilirubin concentration of 270 μmol/L is very high; the exact severity depends on the age of the neonate and the presence of risk factors such as neonatal hemolysis, asphyxia, acidosis, hyperthermia, sepsis, hypothermia, and hypoglycemia.
Usually, jaundice is visible to the naked eye when the bilirubin concentration of the newborn exceeds 85.5~119.7 μmol/L, and it is higher when it reaches 270 umol/L. If the newborn has a total serum bilirubin of 270 μmol/L within 2~4 days of birth and is accompanied by high-risk factors, it is a more serious condition and requires immediate treatment to avoid the development of bilirubin encephalopathy.
If the total serum bilirubin is 270μmol/L after 4 days of life, and there are no high-risk factors, the severity is less serious, usually the jaundice of full-term infants will subside in 5-7 days, the latest not more than 2 weeks; preterm infants will have jaundice subside in 7-9 days, and the longest delay can be up to 3~4 weeks.
Neonatal jaundice value of 270μmol / L if the persistence of jaundice does not subside, should promptly go to the pediatrician to determine the cause of the disease, and actively targeted treatment.
