TRAIT: Antithrombin to Improve Thromboprophylaxis and Reduce the Incidence of Trauma-Related Venous Thromboembolism
Study Details
Study Description
Brief Summary
The purpose of this study is to determine if additional interventions will assist with decreasing the risk and/or severity of thromboembolism (clotting complications) in patients who have experienced a major traumatic event.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Thrombate infusion
|
Drug: Thrombate infusion
Bolus intravenous infusion of Thrombate will be given to achieve antithrombin (AT) activity levels at 150% after the 3rd dose of Enoxaparin. The dose will be based on patient weight.
|
Placebo Comparator: Placebo
|
Drug: Placebo
Normal Saline will be given as one time IV after the 3rd dose of Enoxaparin. The dose will be based on patient weight.
