RESUMO
INTRODUCTION: Severe neonatal hyperbilirubinemia can cause mortality and serious morbidities. When phototherapy fails, neonates with severe hyperbilirubinemia should undergo double volume blood exchange transfusion (BET). As this procedure carries a significant risk of mortality and morbidity, adopting guidelines for the treatment of neonatal hyperbilirubinemia is critical to avoid hyperbilirubinemia toxicity and also the complication of an unindicated procedure. METHODS: This study investigated the causes, complications, and trend of BET rate in our unit over a 13-year period. The medical charts and laboratory databases of all infants who underwent BET in Jordan University Hospital between 2003 and 2015 were retrospectively reviewed. RESULTS: The rate of exchange cases decreased significantly after adopting the guidelines of American Academy of Pediatrics (P<0.0001). Most neonates were term newborns (69%). Average birth weight was 2,800 g. The most common causes of exchange transfusion were non-hemolytic conditions. Late prematurity alone accounted for 20% of the cases. Thrombocytopenia was the most commonly encountered complication (33%). Chronic neurological complications were seen in 12% of those who were followed for >12 months of age. CONCLUSIONS: This study showed a clear decline in the rate of BET after implementing the guidelines of American Academy of Pediatrics. In addition to improving the strategies for the identification and follow-up of at-risk newborns, we should intensify our efforts to prevent the progression of neonatal hyperbilirubinemia to the exchange level by enhancing parents' awareness of this potentially harmful neonatal condition.
