“…1 This significant amount of blood loss leads to swelling, hematoma formation, postoperative stiffness, and possible prolonged drainage, delaying rehabilitation, functional recovery, and hospital discharge, increasing health care costs, often leading to acute anemia and blood transfusion. 2 These features increase the risk of postoperative periprosthetic joint infection, transfusion-related acute lung injury, transfusion-associated circulatory overload, hemolytic transfusion reactions, delayed functional recovery, prolonged hospital stay, and even mortality. 3 Consequently, it is crucial to identify effective methods to minimize perioperative blood loss and reduce the rate of blood transfusion, indicating a need for a critical review of blood conservation practices to optimize operative costs and patient outcomes.…”
