Neonatal jaundice value of 18, i.e. neonatal total bilirubin of 18mg/dl, is usually not serious, but requires early treatment as it is pathologic jaundice. Physiologic jaundice usually occurs in newborns after birth, and it is considered normal as long as the total bilirubin level of full-term newborns does not exceed 12.9mg/dl, and that of preterm infants does not exceed 15mg/dl. When the total bilirubin level of the child exceeds the above normal value, it is called pathological jaundice, but since the total bilirubin level of the child 18mg/dl exceeds the normal value is not too high, it is generally not serious, but still need to be treated as soon as possible. For children with a total bilirubin of 18mg/dl, the first step is to receive blue light irradiation to promote the excretion of indirect bilirubin from the child’s body. Secondly, the child should be given phenobarbital, immunoglobulin and other drugs intravenously as prescribed by the doctor. If the child’s condition does not improve, the total bilirubin level is still high or even continues to rise, and serious conditions such as hemolysis of the newborn occur, the child needs to be treated with blood exchange therapy. When parents find that the total bilirubin level of their newborn is 18mg/dl, they need not be overly nervous and actively cooperate with the doctor to take appropriate treatment. The prognosis of most children with early and timely treatment is good and will not affect their health.
