Thromboelastography-derived Functional Fibrinogen Levels

Comparison of Thromboelastography-derived Functional Fibrinogen Levels During and After Cardiopulmonary Bypass

This study hopes to determine if thromboelastography-derived functional fibrinogen (TEG-FF or FLEV) levels obtained during the rewarming phase of cardiopulmonary bypass can provide information on coagulation status sooner, allowing for anticipation of post-bypass bleeding and transfusion requirements

Inclusion Criteria:

• Elective cardiac surgery patients who are undergoing primary cardiac surgery

Exclusion Criteria:

• Emergency surgery
• Re-operative cardiac surgery
• History of hypercoagulable state as defined in medical record
• Anticoagulated status at time of surgery
• Plasma requirement prior to discontinuation of bypass (alters fibrinogen level)
