AbstractAlthough a number of hemostatic drugs are currently used during surgery to reduce hemorrhage, their effects on bleeding are still controversial. Furthermore, few studies have been made on their prophylactic effects. The purpose of this study was to clarify the effects of hemostatic drugs on bleeding. Thirty adult patients undergoing upper abdominal surgery were randomly assigned to receive carbazochrome sodium sulfonate and tranexamic acid immediately after induction of anesthesia (group H,n=15) or no hemostatic drugs (group C,n=15). Common coagulation-tests [prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB)], thromboelastography [reaction time (R), coagulation time (K), maximum amplitude (MA), clot formation rate (α)], and determination of bleeding time were conducted before induction of anesthesia and just before the completion of surgery. PT, R, and K decreased significantly in both groups, while MA and α increased and FIB decreased significantly in group C. No significant difference in blood loss was observed between the groups. Our findings, therefore, suggest that these two hemostatic drugs do not have prophylactic effects on intraoperative bleeding. Further studies are, however, necessary before applying these results to all surgical patients.
