Use of Coagulation Factor Concentrates and Blood Transfusion in Cardiac Surgery: A Retrospective Cohort Study of Adults with Hereditary and Acquired Bleeding Disorders

Use of Coagulation Factor Concentrates and Blood Transfusion in Cardiac Surgery: A Retrospective Cohort Study of Adults with Hereditary and Acquired Bleeding Disorders Academic Background Cardiac surgery is one of the high-risk procedures, especially for patients with bleeding disorders, as it significantly increases the risk of perioperative bleed...

Effect of Perioperative Blood Transfusion on Preoperative Haemoglobin Levels as a Risk Factor for Long-Term Outcomes in Patients Undergoing Major Noncardiac Surgery: A Prospective Multicentre Observational Study

Academic Background Preoperative anemia and red blood cell (RBC) transfusions are closely associated with poorer surgical outcomes. Although RBC transfusions can increase oxygen delivery, they are also linked to an increased risk of infectious complications, thromboembolic events, pneumonia, sepsis, cardiac events, and mortality. Therefore, when st...
