The purpose of this comparative analysis essay is to discuss the different approaches used for the prevention of postoperative Deep vein thrombosis (DVT). There are a variety of prophylactic treatments to prevent DVT, but for the purpose of this essay only thromboembolic deterrent stockings (TEDs) in relation to Sequential compression devices (SCDs) will be covered and pharmacologic prophylaxis will be covered only briefly. DVT is the formation of blood clots in the deep veins (Kesieme, 2011). The most common sites for thrombus formation are the deep veins within muscle, typically of the calf or the thigh. The clots may dislodge and travel in the blood to the lung and cause pulmonary emboli (PE) (Australian Nursing Journal, 2008). DVT and…show more content…
Prophylaxis against DVT is an important aspect of nursing care and can be achieved using mechanical methods such as TEDs, SCDs and pharmacological methods, for example, subcutaneous injection of low molecular weight heparin (LMWH) (Walker & Lamont, 2008). The key to preventing DVT formation in any patient is to promote perfusion (Maiocco, 2008). In the surgical patient who is non ambulant, TEDs are often used as mechanical prophylaxis of DVT in the lower limb either alone or in combination with other external compression devices or medications. If used alone TEDs have been shown to reduce the relative risk of DVT in surgical patients by 60-80% (Miller, 2011). TEDs exert an even and sustained regressive pressure to the legs, with gradient pressure, decreasing from the ankle to the knee and thigh. This physiological mechanism has the double action of increasing the venous blood flow velocity and preventing venous stasis. TEDs effectively decrease the overall cross-sectional area of the venous system of the lower limbs and increases the linear blood velocity (Autar, 2009).

There is an abundance of evidence that TEDs are very efficacious in the prevention of VTE, either singly or when used in conjunction with other methods of prophylaxis. TEDs are as effective as low dose heparin without the bleeding risk associated with heparin (Autar, 2009). However,
