We sought to assess predictability of excessive bleeding using thrombelastography (TEG), multiplate impedance aggregometry, and conventional coagulation tests including fibrinogen in patients undergoing coronary artery bypass graft (CABG) surgery. ⋯ Multiplate impedance aggregometry identified patients at risk for excessive bleeding after CABG. Low fibrinogen levels were associated with increased bleeding. Neither routine TEG parameters nor conventional coagulation tests were correlated with bleeding.
