title: Dual tracer technique to measure salvaged red cell survival following autotransfusion in aortic surgery.
abstract: The survival of autotransfused red cells was measured for two salvage devices used in 12 elective aortic reconstructions. Six patients underwent cell salvage with the Solco-trans device and six with the Haemonetics cell saver. A double tracer technique was used to take account of post-operative blood loss and fluid replacement. Comparison was made with the results of a group of normal volunteers. A comparison was made of the labelling efficiency of damaged and undamaged red cells using chromium to check that red cells damaged during autotransfusion can be labelled. No significant difference was seen. There was no significant difference in red cell survival between the volunteer group and either of the two salvage device groups. These results suggest that red cell survival is not compromised by the autotransfusion process using these two devices.
