What is a postoperative risk factor for developing DVT?

Postoperative patients are often at a higher risk for developing deep vein thrombosis (DVT) due to several factors, one of which is prolonged bed rest. After surgery, many patients may experience limited mobility and may be required to stay in bed for extended periods. This lack of movement can lead to venous stasis, where blood flow in the veins slows down due to inactivity, increasing the likelihood of clot formation.

In contrast, excessive physical activity, frequent ambulation, and high fluid intake are generally considered protective factors against DVT. Regular movement helps to promote blood circulation, thereby decreasing the risk of clot formation. High fluid intake is also beneficial, as it helps maintain hydration and support healthy blood flow. Therefore, prolonged bed rest is indeed a significant risk factor for developing DVT in the postoperative setting.
