Quantra Point-of-Care Hemostasis Monitoring and Perioperative Blood and Blood Component Transfusion During High-Risk Complex Cardiac Surgery: A Randomized Clinical Trial
The investigators will test the hypothesis that utilization of a blood and blood component transfusion algorithm guided by the POC Quantra QPlus System in patients undergoing complex cardiac surgery will reduce RBC, plasma, cryoprecipitate, and platelet transfusion during surgery and the first 12 postoperative hours, compared to standard of care (central laboratory transfusion monitoring at the primary anesthesia provider's discretion).
• Adults aged 18 years or more
• Scheduled for aortic surgery or high-risk cardiac surgery requiring cardiopulmonary bypass (high-risk surgery includes reoperative surgery, active endocarditis, expected need for intraoperative circulatory arrest, radiation heart disease, end-stage kidney disease requiring renal replacement therapy, combination surgery including more than one valve or valve plus CABG, low left ventricular ejection fraction \[EF\<30%\] with potential need for mechanical circulatory support with intra-aortic balloon pump, extracorporeal membrane oxygenation \[ECMO\], or percutaneous left ventricular assist device)
