In the left panel, the solid line refers to the current recommendation of the American Academy of Pediatrics (AAP) for low-risk infants, the line consisting of long dashes (- - - - -) represents the level at which the AAP recommends phototherapy for infants at intermediate risk, and the line with short dashes (-----) represents the suggested intervention level for infants at high risk. The effect of instituting a prehospital-discharge newborn bilirubin screening program in an 18-hospital health system. The decision to exchange transfuse is not just determined by the level but by the rate of which the increase, which is why it is so important to plot SBR result on a time/SBR level graph.

[Guideline] Atkinson LR, Escobar GJ, Takyama JI, Newman TB. This condition can cause a yellow discoloration of the skin and the whites of the eyes called jaundice. Serial withdrawal and injection of aliquots (5-20 ml) through umbilical vein. Also, because genetic variants in bilirubin metabolism are only exceptionally pursued in the diagnostic work-up of infants with jaundice, their possible contribution to the measured total serum bilirubin is usually unknown. Blanching reveals the underlying colour. [Medline]. Pediatr Res. Pediatrics. To prevent bilirubin encephalopathy (kernicterus) developing as a result of high levels of serum bilirubin. Semin Fetal Neonatal Med. 358(9):920-8. Assess infant for neurological involvement Bhutani VK, Johnson LH, Keren R.

In some LMICs, the incidence of severe neonatal jaundice may be as much as 100 times higher than in higher-income countries. Hepatic excretory capacity is low both because of low concentrations of the binding protein ligandin in the hepatocytes and because of low activity of glucuronyl transferase, the enzyme responsible for binding bilirubin to glucuronic acid, thus making bilirubin water soluble (conjugation). Care of the jaundiced neonate. PATHOPHYSIOLOGY OF JAUNDICE 2. Slusher TM, Olusaniya BO. Br J Hosp Med (Lond). J Paediatr Child Health. [Medline].

However, when inadequate feeding volume is involved, increased enterohepatic circulation of bilirubin probably contributes to prolonged jaundice.
