Evaluation of health outcomes after the implementation of rotational thromboelastometry in patients undergoing cardiac surgery.

Background: Viscoelastic tests (rotational thromboelastometry, ROTEM), together with the implementation of a specific algorithm for coagulation management in cardiac surgery, enable perioperative coagulopathy to be better controlled.

Methods: Retrospective cohort study including 675 patients who underwent cardiac surgery with cardiopulmonary bypass. The incidence of allogeneic blood transfusions and clinical postoperative complications were analyzed before and after ROTEM implementation.
