952 The Use of Cell-Salvage in Periprosthetic Femur Fractures: A Cheaper and Safer Alternative?

Abstract

Abstract Aim Periprosthetic femur fractures (PFF) are becoming increasingly frequent due to an ageing population and growing number of arthroplasties. PFF revision surgery is associated with significant peri-operative blood loss and higher transfusion requirements. There are few strategies to reduce rates of transfusion. One of which is the use of cell-salvage. The aim of this study was to determine whether cell salvage should be routinely implemented during PFF revision surgeries. Method All admission with PFF were retrospectively reviewed over a period of 18 months. Data points including patient demographics, admission/operation dates, fracture site, anticoagulation status, pre/post-op Hb and number of transfusions were collected. Results There were a total of 38 PFF. Average age was 83.4 years with admission Hb 11.65g/dl. Mean time for operation was 2.9 days. 56% of total hip replacement PFF received a blood transfusion post-operatively with an average of 2.6 units per patient. 100% of total knee replacement PFF received a post-operative transfusion with an average of 1.6 units per patient. Of note there was no increased transfusion requirements for patient on anticoagulation (Warfarin/DOAC). Conclusions We identified that >50% of PFF required a post-op transfusion. The cost of 1 unit of RBC locally was found to be £145.99. The average cost of a cell salvage filter is £100 per patient. Considering the above and the well-known risk of allogenic red blood cell transfusion, it was concluded that the routine use of cell salvage could be a cheaper and safer alternative to allogenic red blood cell transfusion.
