Prevention of venous thromboembolism in trauma and long bone fractures.
Patients sustaining traumatic injuries are at high risk for the development of venous thromboembolism. The reported incidence of deep venous thrombosis in trauma patients ranges from 20 to 90%. The reported incidence of pulmonary embolism in trauma patients varies between 2.3 and 22%. The aging population and the survival of more severely injured patients may suggest an increasing risk of thromboembolism in the trauma patient population. There have been few randomized prospective studies assessing methods of thromboembolism prophylaxis in trauma patients. Controversy exists as to the optimal method of prophylaxis in this high-risk population. Contraindications arising from associated injuries often limit the potential options for prophylaxis in patients with trauma. Large prospective randomized studies are needed to determine the most effective means of prophylaxis in trauma patients, who have a wide range of both isolated and combined injuries. Future studies should also address the duration of prophylaxis because many trauma patients remain immobile for an extended time.
