Changes in Red Blood Cell Transfusion Practice during the Turn of the Millennium: A Retrospective Analysis of Adult Patients Undergoing Elective Open Abdominal Aortic Aneurysm Repair Using the Mayo Database

In this retrospective analysis, we observed significantly lower perioperative Hb, fewer allogenic RBC transfusions, and more autotransfusions in open AAA repairs done in 2003-2006 versus those done in 1980-1982. Additionally, late transfusion practice patients were older and had more comorbid diseases. Despite these observations, no significant differences in perioperative morbidity or mortality were observed between groups.
