TEG 6s® for Perioperative Monitoring of Platelet Function During Cardiopulmonary Bypass for Cardiac Surgery

Evaluation of the Diagnostic Performances of the TEG 6s® Hemostasis Device and Its Platelet Mapping® Cartridge for Perioperative Monitoring of Platelet Function During Cardiopulmonary Bypass for Cardiac Surgery

Excessive bleeding is common during cardiopulmonary bypass (CPB) for cardiac surgery. This may result from the systemic activation of the coagulation pathway and the acquired platelet dysfunction during the procedure. This study aims to compare the diagnostic performances of the TEG®6S device and its Platelet mapping® cartridge to those of the "gold standard" tests (light transmittance aggregometry and Multiplate®) for platelet function monitoring in patients undergoing CPB for cardiac surgery.
