Abstract
BACKGROUND: To investigate the efficacy and safety of singleand double-volume exchange transfusion for neonatal hyperbilirubinemia (HB) and compare their effects on the internal environment of newborns. METHODS: The clinical data of 96 HB newborns admitted to and treated in our hospitals from January 2016 to October 2021 were retrospectively analyzed. Then, these newborns were divided into single volume group (80-110 mL/kg, n=48) and double volume group (150-180 mL/kg, n=48) by the exchange volume per unit body mass. The hematological indicators total serum bilirubin (TSB), peripheral blood red blood cell (RBC) count, white blood cell (WBC) count, platelet (PLT) count, serum albumin (ALB), prothrombin time (PT) and activated partial thromboplastin time (APTT), and changes in inner-environment indexes (blood gas, blood glucose, acid-base and electrolyte levels) were compared between the two groups of newborns before treatment and after once treatment. Additionally, the adverse reactions of exchange transfusion in the two groups of newborns were recorded.
