Intraoperative red blood cell transfusion and mortality after cardiac surgery
December 2019—Patients with underlying cardiac disease are at risk for myocardial ischemia if they have untreated anemia at the time of cardiac surgery. During surgery, ongoing blood loss and hemodilution as a result of cardiopulmonary bypass (CPB) cause low hemoglobin levels. The optimal transfusion trigger for cardiac surgery patients continues to be debated. A more restrictive RBC transfusion strategy is used in patients with stable cardiovascular disease and is considered safe.
