title: Prophylactic methods against thromboembolism.
abstract: Deep vein thrombosis and pulmonary embolism are significant hazards of surgery, especially in orthopedic procedures. However, the true incidence of these complications is unknown. Many surgeons are now using prophylactic methods to prevent the postoperative occurrence of thromboembolic disease. Pneumatic compression devices are recommended in some instances, especially in cases where increased bleeding could be devastating. Several pharmacologic agents are also used, alone or in combination with pneumatic devices. These include subcutaneous heparin, warfarin, dextran, and aspirin. Each agent has advantages and disadvantages. The US National Institutes of Health (NIH) and numerous ongoing clinical trials are attempting to establish recommendations and guidelines for the use of prophylaxis against postoperative deep vein thrombosis and pulmonary embolism.
