Acute bilirubin encephalopathy in healthy term neonates requiring exchange transfusion
Intruduction: There is a growing concern about an increasing bilirubin-induced neurological dysfunction (BIND) in healthy term neonates with no evidence of hemolytic disease or other risk factors. This study was done to determine the incidence of BIND in otherwise healthy, breast-fed newborn term infants without hemolysis who underwent exchange transfusion. Methods: This study was conducted i...
متن کاملBilirubin binding in premature infants from birth to 3 months.
The effect of postnatal age on serum bilirubin binding measurements was studied prospectively in extremely premature infants of 25-28 weeks' gestation. Serum was obtained from 10 infants at birth, 2-4 days of age, 1 week, 2 weeks, 4 weeks, 8 weeks, and 10-13 weeks. Using peroxidase oxidation, the apparent unbound bilirubin concentration (AUBC) was measured and plotted versus the molar ratio of ...
متن کاملUnbound bilirubin: a better predictor of kernicterus?
The peroxidase method described in this paper measures non–protein-bound bilirubin by oxidation of the free fraction. The oxidation rate is slow compared with rapid dissociation of albumin-bound bilirubin. Thus, the unbound bilirubin can be estimated from the initial rate of decline in total bilirubin concentration. In the 1970s, severe neonatal hyperbilirubinemia and kernicterus were major cli...
متن کاملIncidence of Chronic Bilirubin Encephalopathy
BACKGROUND AND OBJECTIVES: Despite the implementation of screening guidelines to identify infants at risk for hyperbilirubinemia, chronic bilirubin encephalopathy (CBE) continues to be reported worldwide in otherwise healthy infants. The incidence of CBE in Canada is unknown. The objectives of this study were to establish the incidence of CBE in Canada and identify epidemiological and medical r...
متن کاملSerum bilirubin and bilirubin/albumin ratio as predictors of bilirubin encephalopathy.
BACKGROUND AND OBJECTIVE Bilirubin/albumin ratio (B/A) may provide a better estimate of free bilirubin than total serum bilirubin (TSB), thus improving identification of newborns at risk for bilirubin encephalopathy. The objective of the study was to identify thresholds and compare specificities of TSB and B/A in detecting patients with acute and posttreatment auditory and neurologic impairment...
