| Abstract: | An investigation was made for the significance of changes of coagulation and fibronolytic system in intensive infection with multiple system organ failure (MSOF). In 68 cases with various degrees of infection, hematological examinations, including estimation of PT, APTT, Fg, Fn and D-Dimer, activation of coagulation factor II, VII, X, XII (F II, F VII, F X, F XII), AT-III, PLG, alpha(2)-AP, t-PA and count of platelets were carried out. The results were as follows: In intensive infection with MSOF, PT and APTT increased significantly; activity of F II, F VII, F X and F XII decreased significantly platelet count and Fn decreased markedly; concentration of Fg and D-Dimer increased significantly; activity of PAI increased markedly; activity of t-PA and alpha(2)-AP decreased slightly. The incidence of MSOF not combined with DIC was 38.5%, but that combined with DIC was 79.7% (P < 0.01). It is suggested that DIC is the most important factor in the disorder of coagulation and fibrinolytic system. It play an important role in the pathogenesis and development of MSOF. |
