NCT01264458

Brief Summary

The purpose of this research study is to look at how trauma affects the ability of blood to clot. The blood of people who suffer a traumatic injury can under-clot or over-clot, and this research study will look at blood drawn from people after they suffer a traumatic injury to see how well their blood clots.

Outcome Measures

Primary Outcomes (2)

  • Estimate the distribution over time of procoagulant Microvesicles (MVs) concentration by cell of origin and endogenous thrombin potential (ETP).

    6 months

  • Determine the cumulative incidence of Venothromboembolism (VTE) within three months after major trauma and test the distribution of procoagulant MV concentration and endogenous thrombin generation potential over time as potential predictors of VTE.
