What critical intervention can help prevent venous thromboembolism (VTE) post-surgery?

Early ambulation, along with compression devices if indicated, is a critical intervention for preventing venous thromboembolism (VTE) after surgery. This approach enhances venous blood flow in the legs and helps to reduce the risk of clot formation, which is essential in the postoperative period due to the increased risk of VTE associated with immobility.

Ambulation allows patients to engage their leg muscles, thereby promoting venous return and diminishing stagnation of blood, which is a leading factor in clot development. Additionally, the use of compression devices can further support venous circulation and prevent the pooling of blood in the lower extremities, particularly in those patients who may not be able to ambulate early due to their surgical condition.

Other options, while they may have their merits in specific contexts, do not address the multifactorial nature of VTE prevention as effectively. For instance, administering anticoagulants to all patients might not be appropriate, as some patients may have contraindications or may not need anticoagulation based on their individual risk factors. Increasing fluid intake can be beneficial for hydration but does not directly target venous flow dynamics. Prolonged bed rest can actually increase the risk of VTE, as it contributes to immobility and
