Background: It is not known whether rigorous intraoperative glycemic control reduces death and morbidity in cardiac surgery patients. Objective: To compare outcomes of intensive insulin therapy during with those conventional glucose management. Design: A randomized, open-label, controlled trial blinded end point assessment. Setting: Tertiary care center. Patients: Adults without diabetes who were undergoing on-pump surgery. Measurements: The primary outcome was a composite death, sternal...

Some observational studies have reported that transfusion of red-cell units been stored for more than 2 to 3 weeks is associated with serious, even fatal, adverse events. Patients undergoing cardiac surgery may be especially vulnerable the effects transfusion.We conducted a randomized trial at multiple sites from 2010 2014. Participants 12 years age or older who were complex and likely undergo red cells randomly assigned receive leukocyte-reduced 10 days less (shorter-term storage group) 21...

Bleeding after cardiac surgery is a common and serious complication leading to transfusion of multiple blood products resulting in increased morbidity mortality. Despite the publication numerous guidelines consensus statements for patient management surgery, research has revealed that adherence these poor, as result, significant variability practices among practitioners still remains. In addition, although utilization point-of-care (POC) coagulation monitors use novel therapeutic strategies...

Background Abnormal bleeding after cardiopulmonary bypass (CPB) is a common complication of cardiac surgery, with important health and economic consequences. Coagulation test-based algorithms may reduce transfusion non-erythrocyte allogeneic blood in patients abnormal bleeding. Methods The authors performed randomized prospective trial comparing practices 92 adult CPB. Patients were to one two groups: control group following individual anesthesiologist's protocol using algorithm guided by...
