What is the main purpose of applying elastic stockings postoperatively?

The primary purpose of applying elastic stockings postoperatively is to promote venous return and prevent thromboembolism. After surgery, patients are often at a higher risk of developing deep vein thrombosis (DVT) due to factors such as reduced mobility, changes in blood flow, and the physiological stress of the surgical procedure.

Elastic stockings work by exerting graduated compression on the legs, which helps to enhance venous blood flow back towards the heart. This compression facilitates the return of blood from the lower extremities, thereby reducing the risk of stagnant blood flow that can lead to clot formation. By minimizing venous stasis and improving circulation, these stockings serve as a proactive measure to prevent thromboembolic complications, which are serious concerns in the postoperative setting.

While improving oxygenation, providing warmth, and enhancing mobility are important aspects of post-surgical care, they do not encapsulate the specific purpose and effectiveness of elastic stockings in reducing the risk of thromboembolic events.
