Comparison of Two Different Red Blood Cell Transfusion Thresholds on Short-Term Clinical Outcomes of Patients Undergoing Aortic Surgery With Deep Hypothermic Circulatory Arrest

摘要

Objective: Patients undergoing aortic surgery with deep hypothermic circulatory arrest (DHCA) usually are associated with a high rate of allogeneic blood transfusion, and their red blood cell (RBC) transfusion threshold is unclear and controversial. The purpose of this study was to explore whether a restrictive transfusion threshold was as effective as a liberal transfusion threshold for patients undergoing aortic surgery with DHCA.
