Condition(s) targeted: Brain Injury; Venous Thrombosis

Intervention: Enoxaparin (Drug)

Phase: Phase 4

Status: Suspended

Sponsored by: Minneapolis Medical Research Foundation

To study the safety and efficacy of early administration of Low Molecular Weight Heparin to patients with traumatic brain injury.

Clinical Details

Official title: The Use of Low Molecular Weight Heparin in Traumatic Brain Injury

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double-Blind, Primary Purpose: Prevention

Primary outcome: Safety: Assess if early administration of LMWH exacerbates intracranial hemorrhage.

Secondary outcome: Efficacy: Demonstrate effectiveness of dosing regimen in preventing VTE.

Detailed description: 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.
