![]() 8 Textile properties, including fabric roughness, thermoregulation and dye, may contribute to skin reactions. ![]() For example, in CLOTS (Clots in Legs or Stockings after Stroke) trial 1 - a multicentre randomized controlled trial (RCT) that assessed the effectiveness of thigh-length graduated compression stockings to reduce the risk of deep vein thrombosis after stroke in about 2500 patients - skin breaks, ulcers, blisters and necrosis were significantly more common among patients wearing the stockings than among those not wearing them (5.1% v. 6, 7 Patients who are allergic to the stocking material may develop contact dermatitis, skin discoloration and blistering. The use of graduated compression stockings on legs with impaired arterial flow can worsen ischemia. Poorly fitting stockings can cause discomfort and, at worst, pressure necrosis. 6 – 9 The stockings are generally safe to use, with relatively few complications. The contraindications of graduated compression stockings are listed in Box 3. 4 Another study showed that levels of proinflammatory cytokines (e.g., interleukin-1α, interleukin-6 and interferon-γ) in ulcer tissue in patients with active ulcers were significantly reduced following compression therapy. 2, 4, 5 One study that used near-infrared spectroscopy to monitor changes in tissue oxyhemoglobin and deoxyhemoglobin reported that limb oxygenation increased with the use of graduated compression stockings, especially with high-compression stockings. 3 It also initiates complex physiologic and biochemical effects involving the venous, arterial and lymphatic systems, although the exact mechanisms remain unclear. 2 Graduation compression can reverse venous hypertension, augment skeletal-muscle pump, facilitate venous return and improve lymphatic drainage. The application of adequate graduated compression reduces the diameter of major veins, which increases the velocity and volume of blood flow. The pressure gradient ensures that blood flows upward toward the heart instead of refluxing downward to the foot or laterally into the superficial veins. ![]() The stockings work by exerting the greatest degree of compression at the ankle, with the level of compression gradually decreasing up the garment. What are the mechanisms of action of compression stockings?įigure 2 summarizes the mechanisms of action of graduated compression stockings. They can often be bought over the counter without a prescription They do not need to meet the strict medical and technical specifications as those of graduated compression stockings The compression is uniform and not graduated They usually exert considerably less compression than graduated compression stockings Nonmedical support hosiery, including flight socks and elastic support stockings, are often used to provide relief for tired, heavy and aching legs They are designed for bedridden patients and do not meet the technical specifications for use by ambulatory patientsĪlthough the terms “antiembolism stockings” and “graduated compression hosiery” are often used interchangeably and both types of stockings offer graduated compression, they have different levels of compression and indications Like graduation compression stockings, they provide gradient compression They are designed for ambulatory patients and are manufactured under strict medical and technical specifications, including consistency and durability, to provide a specific level of ankle pressure and graduation of compressionĪntiembolism stockings are used to reduce the risk of deep vein thrombosis They are often used to treat chronic venous disease and edema Graduated compression stockings exert the greatest degree of compression at the ankle, and the level of compression gradually decreases up the garment Graduated or medical compression stockings
