Neonatal jaundice is a yellowish discoloration of the white part of the eyes and skin in a newborn baby due to high bilirubin levels. [1] Other symptoms may include excess sleepiness or poor feeding. [1] Complications may include seizures, cerebral palsy, or kernicterus. [1] In most of cases there is no specific underlying physiologic disorder. [2]
Neonatal cholestasis refers to elevated levels of conjugated bilirubin identified in newborn infants within the first few months of life. [1] Conjugated hyperbilirubinemia is clinically defined as >20% of total serum bilirubin or conjugated bilirubin concentration greater than 1.0 mg/dL regardless of total serum bilirubin concentration.

Uncontrolled levels of bilirubin can be harmful to the baby. [7] Most neonatal jaundice shows during the first week after birth. Nevertheless, when bilirubin levels become exceedingly high, the substance may move out of the blood, cross the blood brain barrier, and collect in brain tissue, damaging the baby's brain cells, a condition known as ...
Bilirubin is not normally detectable in the urine of healthy people. If the blood level of conjugated bilirubin becomes elevated, e.g. due to liver disease, excess conjugated bilirubin is excreted in the urine, indicating a pathological process. [60] Unconjugated bilirubin is not water-soluble and so is not excreted in the urine.
Jaundice, also known as icterus, is a yellowish or greenish pigmentation of the skin and sclera due to high bilirubin levels. [3] [6] Jaundice in adults is typically a sign indicating the presence of underlying diseases involving abnormal heme metabolism, liver dysfunction, or biliary-tract obstruction. [7]
High at birth or rapidly rising bilirubin [2] Prolonged hyperbilirubinemia [2] Bilirubin Induced Neuorlogical Dysfunction [3] Cerebral Palsy [4] Kernicterus [5] Neutropenia [6] [7] Thrombocytopenia [6] Hemolytic Anemia - MUST NOT be treated with iron [8] Late onset anemia - Must NOT be treated with iron. Can persist up to 12 weeks after birth ...

If the bilirubin level is sufficiently high as to cause worry, it can be lowered via phototherapy in the first instance or an exchange transfusion if severely elevated. [citation needed] Phototherapy - Phototherapy is used for cord bilirubin of 3 or higher. Some doctors use it at lower levels while awaiting lab results. [19]
