Perioperative blood management in total hip arthroplasty.

Blood management during total hip arthroplasty is a critical component of successful patient care, and an overall strategy is necessary. Multiple options for blood management are available, including the use of predeposited autologous blood, perioperative blood salvage, hemodilution techniques, erythropoietic agents, hemostatic agents, and allogeneic blood. Rather than relying on automatic so-called transfusion triggers, the surgeon should identify patient-specific risk factors such as the anticipated difficulty of the procedure, preoperative hemoglobin level, comorbidities, and a plan for blood management.
