Are Routine Blood Salvage/Preservation Measures Justified in All Patients Undergoing Primary TKA and THA?

A sequential series of 366 primary total knee arthroplasties and 320 total hip arthroplasties was reviewed to determine the incidence of allogeneic transfusion. Surgery was performed under regional anesthesia and all patients had a hemovac drain for 24 degrees. Tourniquet hemostasis in TKA was maintained through wound closure. Coumadin, SCD and TED hose were utilized for DVT prophylaxis. No additional blood conservation measures were employed. The transfusion incidence in primary TKA was 2.2% (males.6%/females 3.5%). The transfusion incidence in THA was 1.9%, (males.8%/females 2.6%). The low incidence of allogeneic transfusion in a contemporary series of primary TKA and THA, especially in males, would question the need for routine blood preservation techniques in this group of patients.
