Few studies deal with thromboembolic complications in burn patients. The review of the literature and current practice in burn centres point out low, average and high-risk patients, according to the characteristics of the burns wounds. In case of average risk, low molecular weight heparin prophylaxis is suggested. In high risk patients, low molecular weight heparin therapy or continuous intravenous heparin are recommended. This prevention should be continued until the recovery of a normal mobility and complete resolution of inflammation.
