Physical methods for preventing deep vein thrombosis in stroke.
The Cochrane Database of Systematic Reviews
|October 21, 2004
Summary
Physical methods like compression stockings do not significantly reduce deep vein thrombosis (DVT) or pulmonary embolism (PE) in stroke patients. More research is needed to establish their routine use for DVT prevention post-stroke.
Area of Science:
- Neurology
- Vascular Medicine
- Clinical Trials
Background:
- Deep vein thrombosis (DVT) and pulmonary embolism (PE) are significant risks following stroke.
- Anticoagulants reduce DVT/PE risk but carry bleeding risks.
- Physical methods offer a bleeding-risk-free alternative for DVT/PE prevention.
Purpose of the Study:
- To evaluate the efficacy and safety of physical prophylaxis methods for DVT and PE in recent stroke patients.
- To determine if physical methods can prevent DVT and fatal/non-fatal PE after stroke.
Main Methods:
- Systematic review of randomized controlled trials (RCTs) comparing physical DVT prophylaxis with control.
- Searched multiple databases (Cochrane, MEDLINE, EMBASE, CINAHL) up to June 2003.
- Included trials initiated within seven days of stroke onset.
Main Results:
- Two small trials (123 patients total) were identified.
- Compression stockings showed a non-significant trend in reducing DVT.
- Intermittent pneumatic compression did not significantly reduce DVT.
- Overall, physical methods did not show a significant reduction in DVT or death.
Conclusions:
- Current randomized trial evidence is insufficient to recommend routine use of physical methods for DVT prevention in acute stroke.
- Further research is needed to clarify the role of physical methods in stroke patients.
