Transfusion requirements and outcomes in patients undergoing abdominal aortic surgery using intra-operative cell salvage

Abstract

Background: Intraoperative cell salvage (ICS) is the recovery, anticoagulation, filtration and reinfusion of blood lost during surgery. The aim of this study is to determine the safety and efficacy of ICS in emergency and elective abdominal aortic surgery.

Methods: This study reviews volumes of blood loss, blood salvaged with ICS, allogenic blood requirements, and clinical outcomes in patients undergoing abdominal aortic surgery using ICS.

Results: Seventy-nine patients undergoing abdominal aortic surgery are included. Supplemental allogenic blood was not required in 45/79 (57%) of all patients. Transfusion with allogenic blood was not necessary in 41/63 (66%) of elective abdominal aortic aneurysm repairs. ICS was associated with no major complications.

Conclusion: ICS is a safe procedure and substantially reduces the need for blood transfusion in patients undergoing abdominal aortic surgery. It may substantially alleviate shortages of allogenic blood and should be part of the armamentarium of vascular units.
