Anti-embolism stockings are a specific subset of compression socks generally used for patients restricted to bed for recovery. Anti-embolism stockings gently compress the legs to increase circulation, thus reducing the risk of blood clots. They are made of stretchy fabric and exert graduated compression. The stockings are tightest around the ankle but ease up gradually towards the knees.
Anti-embolism stockings are available in two lengths; thigh-high and knee-high. While thigh-high provides a broader compression benefit around your leg region, the knee-high is limited and less constricting. Also, some anti-embolism socks have a small hole around the toes so caregivers can monitor the patient's circulatory status without removing the stockings.
Anti-embolism socks exert graduated pressure on the extremities, highest pressure towards the feet and ankle, and lessening as it moves up the leg that helps blood flow toward the heart. The pressure gradient gently compresses the veins in the legs, preventing them from expanding and the blood from pooling or seeping sideways into superficial veins in the leg. The squeezing action of the stockings also makes the veins a bit narrower, increasing the speed of blood flow. Thus, reducing swelling, inflammation, and the risk of venous thromboembolism in the process.
Anti-embolism socks are not safe for everyone. They are not appropriate for people with the following health conditions, including:
The key differences between anti-embolism stockings and compression stockings are the compression level and the medical reason for which they are worn. Anti-embolism stockings usually have a compression level of are 8-18 mmHg, while compression stockings vary in compression level. They are measured 15-20 mmHg or higher.
The purpose of anti-embolism stockings is to prevent blood pooling and reduce the risk of blood clotting in a bedridden patient. In contrast, compression stockings are designed to meet the needs of ambulatory patients, and they focus on improving blood flow. Doctors recommend compression stockings for treating conditions like varicose veins, edema, chronic venous insufficiency, deep vein thrombosis, lymphedema, phlebitis and are even used during pregnancy to prevent swelling.
