“…[25][26][27][28][29][30][31][32][33][34] Some have found a positive correlation between APTT and postoperative hemorrhage following cardiac surgery. 26,28,30,[35][36][37][38][39] Very few studies, in fact, have specified their transfusion algorithms for the management of hemorrhage, [26][27][28]40 thus making it difficult to ascertain how elevated APTT was interpreted and dealt with in most studies.…”

“…Bleeding is especially likely to stop in time in branches of the internal thoracic artery (a common source of bleeding), due to vasospasm or coagulum compression. TEG has been shown to be an indispensable tool for distinguishing between surgical and nonsurgical bleeding 5 . This examination was applied in 57.1 % of our cases, but diagnosed coagulation disorder in only 14.2 % of the examined patients.…”

Aims: Cardiac surgery patients are prone to bleeding postoperatively owing to the extensive sternotomy wound, multiple vessel and heart sutures, and disorders of hemostasis. In this study we retrospectively analyzed the outcomes for all patients in our department who were re-operated for bleeding, over a 5 year period.Methods: A total of 4297 patients underwent heart surgery between February 2002 and January 2007, of which 98 (2.3 %) were emergency reoperations for bleeding. We analyzed the process of indication for repeat surgery, possible source of bleeding, and postoperative complications.Results: Most (85.7 %) of the reoperated patients had undergone their fi rst operation as an elective cardiac procedure. The mean blood loss before the reoperation was 1557 ml. The studied group was characterized by increased mortality (11.2 %), longer ventilation period (35.1 hours) and ICU (4.5 days) and hospital (13.3 days) stays. The postoperative outcomes did not diff er signifi cantly between patients with TEG-detected coagulation disorder and the rest of the patients, or between patients treated with antilysin and those who did not receive antifi brinolytics.Conclusions: It is vital for the indication process leading to reoperation of the bleeding patient to be as short as possible so as to minimize the delay to repeat surgery. Echocardiography including ultrasound of both pleural spaces, and TEG could shorten that time delay, and should always be included when evaluating patients. Platelets should be administered more often, with the use of antifi brinolytics reserved for cases with confi rmed fi brinolysis.

“…Whilst the bleeding time and platelet count had sensitivities similar to thromboelastography, thromboelastography specificity was greater. In addition, they suggested that patients with abnormal thromboelastography were at increased risk of bleeding but the excessive bleeding in the face of a normal thromboelastography implied surgical bleeding and FFP and platelets should not simply be used empirically [28].…”
