Impact of Red Cell Salvage on Transfusion Requirements During Elective Abdominal Aortic Aneurysm Repair

Abstract

Elective abdominal aortic aneurysm (AAA) surgery may result in substantial blood loss. Concerns regarding the safety, availability, and acceptability of homologous blood have led to initiatives toward reducing transfusion requirements at the time of aneurysm repair. This study was designed to determine if the routine use of intraoperative red cell salvage and autotransfusion resulted in a reduction in homologous transfusion at our institution. A retrospective review of elective AAA repairs in the years 1987, 1992, and 1997 was carried out. Demographic data, operative details, blood loss, hemoglobin levels, red cell salvage and return volumes, and transfusion requirements were recorded and compared across the study years. From this study we conclude that routine use of red cell salvage and autotransfusion is an effective means for reducing transfusion requirements in elective AAA repair.
