![]() ![]() This causes an accumulation of bilirubin in the blood ( hyperbilirubinemia), leading to the symptoms of jaundice. In newborns, jaundice tends to develop because of two factors-the breakdown of fetal hemoglobin as it is replaced with adult hemoglobin and the relatively immature metabolic pathways of the liver, which are unable to conjugate and so excrete bilirubin as quickly as an adult. Įxchange transfusions performed to lower high bilirubin levels are an aggressive treatment. High pitched crying is an effect of kernicterus. Infants with kernicterus may have a fever or seizures. Quick and accurate treatment of neonatal jaundice helps to reduce the risk of neonates developing kernicterus. Prolonged hyperbilirubinemia (severe jaundice) can result in chronic bilirubin encephalopathy ( kernicterus). For the feet to be affected level generally must be over 255 μmol/L (15 mg/dL). Ī bilirubin level more than 34 μmol/L (2 mg/dL) may be visible. Other symptoms may include excess sleepiness or poor feeding. The primary symptom is yellowish discoloration of the white part of the eyes and skin in a newborn baby. īronze baby syndrome (dark pigmentation of skin). Globally over 100,000 late-preterm and term babies die each year as a result of jaundice. Of babies that are born early about 80% are affected. The condition affects over half of babies in the first week of life. Physiologic jaundice generally lasts less than seven days. In those who are born early more aggressive treatment tends to be required. Treatments may include more frequent feeding, phototherapy, or exchange transfusions. The need for treatment depends on bilirubin levels, the age of the child, and the underlying cause. In those with concerning findings further investigations to determine the underlying cause are recommended. Concerns, in otherwise healthy babies, occur when levels are greater than 308 μmol/L (18 mg/dL), jaundice is noticed in the first day of life, there is a rapid rise in levels, jaundice lasts more than two weeks, or the baby appears unwell. A bilirubin level more than 34 μmol/L (2 mg/dL) may be visible. In other cases it results from red blood cell breakdown, liver disease, infection, hypothyroidism, or metabolic disorders (pathologic). In most of cases there is no specific underlying physiologic disorder. Complications may include seizures, cerebral palsy, or kernicterus. ![]() Neonatal jaundice is a yellowish discoloration of the white part of the eyes and skin in a newborn baby due to high bilirubin levels.
