Comparing two dosing regimens of Lovenox for preventing blood clots in trauma and surgery patients

A Prospective Randomized Trial Comparing Two Standard Doses of Enoxaparin for the Prevention of Thromboembolism in Surgical Patients

Phase 4 Interventional Oregon Health and Science University · NCT02342444

This study is testing whether giving trauma and surgery patients Lovenox twice a day or once a day is better at preventing blood clots and causing fewer bleeding issues.

What this trial studies

This clinical trial aims to compare the effectiveness and safety of two dosing regimens of enoxaparin (Lovenox) in preventing blood clots in patients admitted to trauma or surgical services. Participants will be randomized to receive either 30 mg of enoxaparin twice daily or 40 mg once daily. The study will monitor the development of deep vein thrombosis (DVT) and assess any bleeding complications associated with each dosing regimen. Data on patient characteristics and outcomes will be collected throughout the study.

Who should consider this trial

Good fit: Ideal candidates for this study are patients over 15 years old who are admitted to trauma or surgical services and require prophylactic dosing of enoxaparin.

Not a fit: Patients who are unable to provide consent, have intracranial hemorrhage, or are receiving therapeutic doses of anticoagulation will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the optimal dosing of enoxaparin, potentially reducing the risk of blood clots and associated complications in high-risk patients.

How similar studies have performed: While similar studies have explored enoxaparin dosing, this specific comparison in trauma and surgical patients is novel and has not been directly tested before.
