Sequential Compression Device

A Sequential Compression Device (SCD) is a method of DVT prophylaxis that enhances venous return, thus preventing venous stasis, a risk factor for deep vein thrombosis (DVT). SCDs are sometimes referred to as an intermittent pneumatic compression device (IPC).

Mechanism of action

The SCD works by using inflatable sleeves or stockings that wrap around the leg and inflate with air one at a time in a sequence, which pushes blood up towards the heart. This helps to increase the speed of blood flow in the deep veins of the legs, reducing the chance of clotting.

Indications

SCDs are used in patients who are at risk for developing DVT, including those who are immobile or bedridden, have had recent surgery, or have a history of DVT or pulmonary embolism (PE). They are also used in patients who are contraindicated for anticoagulant therapy.

Contraindications

SCDs should not be used in patients with severe peripheral vascular disease, recent skin grafts, or dermatitis. They should also not be used in patients with known or suspected DVT or PE.

Complications

While SCDs are generally safe, they can cause discomfort, skin irritation, and bruising. In rare cases, they can cause nerve damage or increase the risk of DVT if not used properly.
