Which interventions are helpful to prevent venous thrombosis after major abdominal surgery?

The use of sequential compression devices is a well-established intervention for preventing venous thrombosis, especially following major abdominal surgery. These devices work by applying intermittent pressure to the legs, which enhances venous blood flow and reduces the risk of clot formation. The mechanics of this intervention stimulate circulation by mimicking the natural muscle pump action that occurs during movement, thereby preventing stasis of blood in the veins, which is a primary factor in developing deep vein thrombosis (DVT).

In the context of post-surgical recovery, patients may have reduced mobility due to pain or medical restrictions. This lack of movement increases the likelihood of venous stasis. Sequential compression devices are particularly valuable because they provide an external means of promoting circulation, even when the patient is confined to bed rest.

Hydration is important in overall postoperative care to maintain blood volume and proper circulation; however, it is not as directly effective in preventing thrombosis as mechanical interventions like sequential compression devices. Application of heat to the limbs can potentially lead to dilation of blood vessels but does not confer the same preventive benefits against venous thromboembolism. Frequent blood tests, while critical for monitoring various aspects of health post-surgery, do not play a role in preventing venous thrombosis.
