The compression stockings were applied on the day before surgery or on the day of surgery and were worn up until discharge or until the patients were fully mobile. Of the 20 trials, 10 included patients undergoing general surgery six included patients undergoing orthopaedic surgery three individual trials included patients undergoing neurosurgery, cardiac surgery, and gynaecological surgery, respectively and only one trial included medical patients (patients who were admitted to the hospital for reasons other than surgery). The other methods used were dextran 70, aspirin, heparin, and mechanical sequential compression. ![]() Nine trials compared wearing stockings to no stockings, and 11 compared stockings plus another method with that method alone. We identified 20 randomised controlled trials (studies in which participants are assigned to a treatment group using a random method) (2853 analytic units consisting of 1681 individual patients and 1172 individual legs) in our most recent search on 12 June 2018. Graduated compression stockings (GCS) help prevent the formation of blood clots in the legs by applying varying amounts of pressure to different parts of the leg. Drugs can cause bleeding, which is a particular concern in surgical patients. Deep vein thrombosis usually resolves, but it can have long-term effects such as high venous pressure in the leg, leg pain, swelling, darkening of the skin, and inflammation.ĭeep vein thrombosis can be prevented with the use of compression or drugs. The main treatment for DVT includes the use of blood-thinning drugs (anticoagulation). A blood clot can move from the leg to the lungs, with the danger of pulmonary embolism (PE) and death. Symptoms of DVT vary from none to pain and swelling in the legs. ![]() Hospital patients, who often have one or more of these risk factors, are at particular risk of developing DVT, either immediately after surgery or if they are immobile due to a medical illness. ![]() A number of factors such as reduced mobility, older age, obesity, active cancer, major surgery, major injuries, history of previous DVT, family history of DVT, and recent period of illness may increase the risk of developing a DVT. Deep vein thrombosis (DVT) is a blood clot that forms in a vein deep in the body, usually in the leg or pelvic veins.
