Intra-operative intravenous fluid restriction reduces perioperative red blood cell transfusion in elective cardiac surgery especially in transfusion-prone patients: a prospective randomized controlled trial

摘要

BackgroundCardiac surgery is a major consumer of blood products, and hemodilution increases transfusion requirements during cardiac surgery under CPB. As intraoperative parenteral fluids contribute to hemodilution, we evaluated the hypothesis that intraoperative fluid restriction reduces packed red-cell (PRC) use, especially in transfusion-prone adults undergoing elective cardiac surgery.
