ObjectiveTo compare the effects of crystalloid and colloid solutions, tranexamic acid and epsilon-aminocaproic acid on the need for allogenic blood transfusion and on coagulation and fibrinolysis parameters.MethodsWe conducted the study in the Anesthesiology and Reanimation Department of Hacettepe University Medical Faculty, Ankara, Turkey between March 2004 and April 2005. The study included 105 patients, classified by the American Society of Anesthesiology as physical status groups I-II, undergoing gynecologic cancer treatment. We divided them into 5 groups: group I (crystalloid) received crystalloid solutions, group II (colloid) received colloid solutions, group III (tranexamic acid) received 10 mg x kg(-1) tranexamic acid, and group 5 (epsilon-aminocaproic acid) received 100 mg x kg(-1) epsilon-aminocaproic acid. All patients bleeding amount was measured and recorded perioperatively, and at the 12th and 24th hours postoperatively. We then evaluated the patients' hemoglobin, hematocrit, activated thromboplastin time, international normalized ration, fibrinogen, and thrombocyte count and symptoms of pulmonary embolism.ResultsIn comparing the amount of bleeding, the bleeding in the tranexamic acid group was 30.8% less than the crystalloid group (p<0.05), 33.3% less than the colloid group (p<0.05), and 23.9% less than the epsilon-aminocaproic acid group (p<0.05).ConclusionWhen the negative effects of blood transfusions were considered, tranexamic acid administration can be recommended for decreasing the need for blood transfusion in gynecologic cancer surgery.
