  • Title: Minimizing blood transfusions during abdominal aortic surgery: recent advances in rapid autotransfusion.
    Author: Hallett JW, Popovsky M, Ilstrup D.
    Journal: J Vasc Surg; 1987 Apr; 5(4):601-6. PubMed ID: 3560352.
    Abstract:
    The purpose of this study was to determine what percentage of patients could avoid the transfusion of any homologous bank blood products during elective abdominal aortic surgery with a recently developed semicontinuous, rapid autotransfusion device. Fifty patients (26 with abdominal aortic aneurysms and 24 with aortic occlusive disease) prospectively received intraoperative autologous transfusion (group 1) and were matched for comparison with 50 patients receiving homologous blood without use of any autotransfusion equipment (group 2). For the entire perioperative period, 34 group 1 patients (68%) received only their own autotransfused blood and no other homologous blood components compared with group 2 in which 48 patients (96%) required some bank blood (p less than 0.0001). Rapid autotransfusion reduced usage of homologous red cell transfusion by 75%. The mean postoperative hemoglobin was similar in both groups (group 1, 11.91 gm/dl vs. group 2, 11.90 gm/dl, p = 0.73). Rapid autotransfusion was not associated with significant hemolysis, air embolism, or coagulopathy and did not increase morbidity or death. By eliminating the need for any bank blood components in most patients, rapid autotransfusion minimizes the risk of blood-borne diseases and transfusion reactions. New rapid autotransfusion devices offer a distinct advantage over past equipment and allow significant changes in current transfusion practices during elective abdominal aortic reconstructions.
