Abstract:
BACKGROUND: After multiple trauma, blood coagulation activity is enhanced and fibrinolytic activity is suppressed by overproduction of plasminogen activator inhibitor-1 (PAI-1). Intermittent sequential pneumatic compression (ISPC) is an effective method to prevent deep vein thrombosis. Its action is explained by the mechanical effect on blood flow, as well as by the enhancement of fibrinolysis by the reduction of PAI-1. The aim of this study was to determine the effects of ISPC on coagulation and fibrinolysis after multiple trauma. METHODS: Thirty-nine trauma patients were either treated with ISPC (ISPC group, 20 patients) or without ISPC (control group, 19 patients). We measured the plasma levels of the thrombin antithrombin III complex (TAT), the plasmin alpha 2 plasmin inhibitor complex (PIC), the tissue plasminogen activator (t-PA), and the plasminogen activator inhibitor-1 (PAI-1) on admission and at 1, 2, 3, 6, 12, and 24 hours after admission. RESULTS: The TAT was higher than normal in both groups, with no significant difference between the two groups throughout the study period. The PIC level of ISPC group was significantly higher than that of the control group. In the ISPC group, the PIC level increased gradually, reaching a peak at 3 hours and decreasing thereafter. In the control group, the PIC level increased to a peak level at 2 hours. The TAT/PIC ratio dropped in the first two hours and increased at 3 hours, dropping again thereafter. In the ISPC group, the ratio dropped gradually without an intermittent fluctuation. At 3 and 6 hours, the control group showed a significantly greater ratio compared to the ISPC group. PAI-1 was higher than normal in bothgroups, with a significantly lower level in the ISPC group from 2 hours to 24 hours. For the t-PA level, no difference was noted between the two groups, with the peak level occurring at 1 hour. The PAI-1/t-PA ratio was significantly greater in the control group from 2 hours to 12 hours than in the ISPC group, but the difference was not significant at 24 hours. CONCLUSIONS: In multiple trauma patients, ISPC does not seem to affect coagulation, but enhances fibrinolysis through suppressed PAI-1 production. This effect of ISPC may be maintained for 12 hours.
