Study on the application value of red blood cell distribution width and platelet distribution width in neonatal exchange transfusion with hyperbilirubinemia

Abstract

Abstract Purpose The study aimed to evaluate the application of Red Blood Cell Distribution Width (RDW) and Platelet Distribution Width (PDW) in the treatment of neonatal exchange transfusion (ET) with hyperbilirubinemia as well as to provide relevant reference materials for clinical diagnosis and treatment. Patients and methods This was a retrospective study in a single center. Between January 2011 and December 2020, a total of 198 neonates, who were admitted to Fujian Maternity and Child Health Hospital for hyperbilirubinemia and treated with ET therapy were selected. They were divided into blood group antibody negative (BGAbN) ET (n = 92) and blood group antibody positive (BGAbP) ET (n = 106) groups. We analyzed changes in serum total bilirubin (STB), serum indirect bilirubin (SIB), and platelet count(PLT) before and after ET; The clinical data of the neonates with hyperbilirubinemia were collected, and RDW and PDW were compared in the two groups before ET.. Results The concentrations of STB, SIB, and platelet count were much higher before ET and decreased significantly after ET; the difference was statistically significant (p<.001); There were significant differences between the two groups in RDW and PDW before ET. Conclusion ET therapy is the most timely and effective treatment method for severe hyperbilirubinemia in neonates clinically; RDW and PDW can help determine neonatal hemolysis caused by blood group antibodies.
