Abstract
Perioperative anemia and red blood cell transfusions are important risk factors for morbidity and mortality in cardiac surgery. Preoperative anemia is common, with up to 50% of patients presenting for cardiac surgery affected. Iron deficiency-the most common and potentially modifiable cause of preoperative anemia-is a major driver of blood transfusions in the cardiac surgical setting, adversely affecting both patient outcomes and resource utilization. Perioperative blood management, a patient-centered approach to blood conservation during cardiac surgery, is a multidisciplinary collaborative effort among anesthesiologists, surgeons, perfusionists, intensivists, and transfusion laboratory teams. Strategies aim to reduce blood loss and transfusions and improve patient outcomes. There has been a recent increase in research related to anemia, iron deficiency, and patient blood management in cardiac surgery. This scientific statement highlights the latest evidence on preoperative anemia assessment and intraoperative blood conservation; discusses considerations for specific patient populations regarding anemia prevalence, treatment, and outcomes; and reviews key challenges and knowledge gaps, with the goal of minimizing the impact of preoperative anemia, intraoperative blood loss, and hemodilution on cardiac surgery outcomes.
