Comparing arterial and venous blood coagulation during heart surgeries

Prospective, Monocentric Study of the Interchangeability of Arterial Coagulation and Venous Coagulation, in the Context of Cardiac Surgeries Under Cardiopulmonary Bypass, Using the DMDiv Hemochron Signature Elite

Observational Centre Hospitalier Universitaire, Amiens · NCT05875272

This study is testing if measuring blood clotting in arteries is just as good as measuring it in veins for patients having heart surgery.

What this trial studies

This observational study investigates the interchangeability of arterial and venous coagulation measurements during cardiac surgeries that utilize cardiopulmonary bypass. It employs the Hemochron Signature Elite device to assess coagulation levels in patients undergoing various heart procedures. The study aims to determine if the chemical differences between arterial and venous blood affect the accuracy of coagulation results, which are critical for safe anticoagulation management during surgery.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and over who are scheduled for conventional heart surgeries under normothermic cardiopulmonary bypass.

Not a fit: Patients undergoing emergency surgeries, those with heparin-induced thrombocytopenia, or minors will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the safety and effectiveness of anticoagulation management during cardiac surgeries.

How similar studies have performed: While similar studies have explored coagulation management, this specific comparison of arterial versus venous coagulation in the context of cardiopulmonary bypass is relatively novel.
