| Outline of Final Research Achievements |
To elucidate the mechanisms of trauma-induced coagulopathy, prospective and retrospective studies were performed. We demonstrated that trauma itself induces changes in coagulation and fibrinolysis, which consists of activation of coagulation (thrombin generation), insufficient anticoagulation systems (TFPI, antithrombin, protein C and thrombomodulin), and inhibition of fibrinolysis by PAI-1. The conditions are coincided with the pathophysiology of disseminated intravascular coagulation (DIC). These evidences were also confirmed by experimental studies using Noble-Collip Drum rat trauma models. Base on the results, we have published several original studies and review articles including one systematic review. To confirm these phenomenon, we, have conducted prospective multicenter study recruiting 108 institutes in Japan. The study has now completed and is waiting the publication of the obtained results in the English journal.
