It seems intuitive that autotransfusion would reduce the amount of bank blood required during open AAA repair. Indeed, abdominal aortic repair would seem to be the optimal operation for autotransfusion, given the potential for effusive blood loss and the small amount of particulate matter. Yet, after more than 20 years of autotransfusion experience, vascular surgeons are uncertain as to whether autotransfusion is the standard of care or whether it provides a benefit in reducing ABTs.
Dr Takagi and colleagues analyzed whether autotransfusion reduces allogeneic bank blood transfusions in abdominal aorta surgery using 4 randomized controlled trials.1-4 Patients in the studies underwent AAA repair and were randomized to either the autotransfusion or the control (no autotransfusion) group. Their results suggest that autotransfusion significantly reduces the need for allogeneic blood.
The meta-analysis is hampered by the disparate results of Clagett et al,4 which showed . . . [Full Text of this Article]
