Impact of prestorage leucoreduction of autologous whole blood on length of hospital stay with a subgroup analysis in bilateral hip arthroplasty.

Background: Although prestorage leucoreduction (LR) of blood components for transfusion has gained favour around the world, evidence of its beneficial clinical effects is ambiguous. Study design and methods: To reveal whether leucocytes and/or platelets in transfused blood are related to transfusion‐related adverse effects, a prospective randomized crossover study was performed on patients who donated autologous blood prior to elective surgery. Among 1487 primary enrolees, a total of 192 patients undergoing two‐stage, bilateral total hip arthroplasty were randomized to receive autologous blood that was either prestorage leucoreduced, or not, for the first procedure. For the second procedure, each patient was crossed over to receive alternatively processed autologous blood. Length of hospital stay served as a primary end‐point, with perioperative infectious/thrombotic complications, pre‐ and postoperative laboratory values, and body temperature serving as secondary endpoints. Results: No significant differences emerged between prestorage LR and non‐LR cohorts in length of hospital stay, as well as perioperative infectious/thrombotic complications, postoperative body temperature and duration of fever. Postoperative laboratory values including white blood cell counts and C‐reactive protein levels had no significant differences. Conclusion: This study could not prove any superiority of prestorage LR over non‐LR for autologous whole blood among patients who underwent total hip arthroplasty. [ABSTRACT FROM AUTHOR]
