What intervention can help prevent deep vein thrombosis (DVT)?

Encouraging ambulation and leg exercises is an effective intervention for preventing deep vein thrombosis (DVT) because it promotes circulation in the lower extremities. When a person is inactive for extended periods, such as during surgery or prolonged bed rest, blood flow can decrease in the legs, increasing the risk of clot formation. By encouraging patients to move, whether through regular ambulation or specific leg exercises—such as ankle pumps or foot circles—blood flow is enhanced, helping to prevent the stasis of blood that can lead to DVT.

This proactive approach is essential in both hospitalized patients and those at risk for DVT in outpatient scenarios. Additionally, leg exercises can strengthen the muscles in the legs, contributing to better venous return and reduced risk of clot formation, creating a healthier vascular environment.

Other strategies may support DVT prevention, such as hydration and anticoagulant therapy, but these are supplementary to the primary method of promoting activity and movement.
