Abstract
PURPOSE: To investigate the impact of minor perioperative bleeding requiring transfusion of 1-2 red blood cell (RBC) units on the outcome after coronary artery bypass grafting (CABG).
METHODS: Sixteen cardiac surgical centers contributed to the prospective European CABG registry (E-CABG). 1014 patients receiving 1-2 RBC units during or after isolated CABG were compared to 2264 patients not receiving RBCs.
RESULTS: In 827 propensity score matched pairs, transfusion of 1-2 RBC units did not affect the risk of in-hospital/30-day death (p=0.523) or stroke (p=0.804). However, RBC transfusion was associated with an increased risk of acute kidney injury (p=0.008), sternal wound infection (p=0.001), postoperative use of antibiotics (p=0.001), prolonged use of inotropes (p<0.0001), use of intra-aortic balloon pump (p=0.012), length of intensive care unit stay (p<0.0001) and length of in-hospital stay (p<0.0001). Matched paired analysis excluding pre- and postoperative critical hemodynamic conditions showed that RBC transfusion was associated with an increased risk of major complications except in-hospital/30-day death.
CONCLUSION: Minor perioperative bleeding and subsequent transfusion of 1-2 RBC units did not affect the risk of early death, but increased the risk of other major adverse events. Minimizing perioperative bleeding and prevention of even low-volume RBC transfusion may improve the outcome after CABG.
