Newborn bilirubin over 400

Bilirubin is a substance in human bile that can be used to diagnose neonatal jaundice. Neonatal jaundice is a normal symptom. There is no problem as long as it does not exceed normal indicators. In some newborns, jaundice will disappear on its own in a short time. However, if the neonatal jaundice exceeds the normal indicators, it is necessary to go to the hospital for examination. Generally, blue light irradiation is the safest treatment method. Parents should pay more attention to whether the baby has any special symptoms.

What will happen if the newborn baby has jaundice of more than 400?

①The normal value of neonatal jaundice is based on serum bilirubin as a reference indicator. It is normal as long as the full-term infant does not exceed 204μmol/L (12mg/dl) and the premature infant does not exceed 255μmol/L (15mg/dl). Jaundice in children is caused by increased bilirubin in the body. Generally, pediatric jaundice can be divided into physiological jaundice and pathological jaundice. Physiological jaundice refers to jaundice that is discovered in children 24 hours after birth and disappears naturally within 14 days without any other symptoms; pathological jaundice has different manifestations, such as neonatal hemolytic disease, neonatal sepsis, neonatal hepatitis, congenital biliary atresia, etc. When jaundice is found in children, it is important to use symptomatic medication.

②If the baby's spirit and diet are normal after birth, and there are no mental abnormalities, the impact should not be significant and will not have much impact on the baby's future intelligence and development. However, if there are mental and dietary abnormalities, or even vomiting, you should pay attention and observe.

Normal value of neonatal jaundice

①The normal jaundice value for full-term babies is different from that for premature babies. Generally, the normal value of jaundice in full-term newborns is 12.9 mg/100 ml, which means that the bilirubin level in 100 ml of blood is lower than 12.9 mg. The normal value of jaundice in premature babies is 15 mg/100 ml of blood, which means that the bilirubin level in 100 ml of blood is less than 15 mg.

② When the baby's jaundice value exceeds 12.9mg/dl or the neonatal jaundice index rises too quickly (rising by more than 5mh/dl per day), or the jaundice lasts longer than the time it takes for a full-term baby to disappear within 14 days and for a premature baby to disappear within 4 weeks, or the jaundice disappears and reappears. It means that the neonatal jaundice is unhealthy and may be suffering from pathological jaundice.
