The use of blood cell salvage in acetabular fracture internal fixation surgery

To determine if the routine use of intraoperative blood cell salvage in acetabular fracture internal fixation reduces the need for allogenic blood transfusion, is cost effective, and whether it is influenced by the acetabular fracture pattern.

A retrospective study.

Tertiary pelvic and acetabular reconstructive center.

Patients undergoing internal fixation for acetabular fractures.

Eighty consecutive patients were reviewed, comprising 26 elementary fracture (EF) and 54 associated fracture (AF) types. The mean volume of autologous blood transfused was 484 mL. The mean volume of 561 mL of autologous blood transfused in patients with AF types was significantly greater than the mean volume of 325 mL transfused in the EF group (P = 0.007). Additional allogenic blood transfusion was required in 5 (19%) patients with EFs and 15 (28%) patients with AFs (P = 0.418). The mean cost of the blood cell salvage and additional blood products in our study was $223 (£135) for all fracture types ($174/£105 for EF and $246/£149 for AF).When treating AF types, the mean cost of using blood cell salvage was $246 (£149) as compared with the mean predicted cost of not using blood cell salvage and transfusing the equivalent of 1.7 units of allogenic blood instead, which was $463 (£281). These distributions are significantly different (P = 0.01).

The use of blood cell salvage for internal fixation surgery for acetabular fracture is cost effective, particularly when treating AF types, and its routine use is advocated to limit the need for allogenic blood transfusion.
