Condition(s) targeted: Brain Injury; Venous Thrombosis
Intervention: Enoxaparin (Drug)
Phase: Phase 4

To study the safety and efficacy of early administration of Low Molecular Weight Heparin to
patients with traumatic brain injury.
Official title: The Use of Low Molecular Weight Heparin in Traumatic Brain Injury
Study design: Prevention, Randomized, Double-Blind, Placebo Control, Parallel Assignment, Safety/Efficacy Study
Primary outcome: Safety: Assess if early administration of LMWH exacerbates intracranial hemorrhage.
Secondary outcome: Efficacy: Demonstrate effectiveness of dosing regimen in preventing VTE.
Venous thromboembolic (VTE) prophylaxis in trauma patients is a critical clinical problem.
Patients with traumatic brain injury usually have effective VTE prophylaxis withheld
secondary to concerns of exacerbating intracranial hemorrhage. This study examines the
safety and efficacy of early administration (within 24 hrs of admission) of low molecular
weight heparin to this patient population with very high VTE risk.
Minimum age: 18 Years.
Maximum age: N/A.
- Blunt traumatic brain injury (Marshall II-V)
- Stable 6 hr. head CT
- Stable hemoglobin
- Premorbid coagulopathy
- < 18 y. o.
- Need for therapeutic anticoagulation
- Heparin allergy
