title: Intraoperative blood salvage in revision total hip arthroplasty: who benefits most?
abstract: The purpose of the present study was to identify factors that predict reinfusion following intraoperative blood salvage (IOBS). We retrospectively identified 298 patients who underwent aseptic revision total hip arthroplasty at our institution between February 2005 and January 2007. Of these, 160 (53.7%) received reinfusion from IOBS. In the reinfusion group, an average of 850 mL (range, 300-4300) of fluid was collected and an average of 270 mL (range, 135-1350) of red blood cells was returned. Exchange of both the femoral and acetabular components, use of a trochanteric osteotomy, increased body mass index, and advanced age were associated with reinfusion. Based on these results, surgeons may consider using IOBS on patients with these preoperative characteristics.
