NCT01455454

Brief Summary

Coagulopathy with transfusion requirements is frequent during cardiac surgery with cardiopulmonary Bypass. Rotational thromboelastrometry (ROTEM®) is a viscoelastic whole blood point of care test used to assess the patient's coagulation status. The purpose of this study is to evaluate the feasibility of ROTEM® analysis in the presence of very high heparin concentrations as seen during cardiopulmonary bypass.

Outcome Measures

Primary Outcomes (1)

  • Change from baseline ROTEM® measurements after the administration of heparin

    Baseline ROTEM® measurement will be compared to ROTEM® measurements after the administration of heparin, at the end of cardiopulmonary bypass and after the administration of protamine.
