Guidelines for venous thromboembolism prevention include the use of pharmacological thromboprophylaxis, mainly with low-molecular-weight heparin, and\u002For mechanical thromboprophylaxis. However, a high incidence of venous thromboembolism is observed despite standard dose thromboprophylaxis (such as enoxaparin 40 mg once daily).\n\nAn increase of the dose of anticoagulants could improve thromboprophylaxis in trauma patients. To date, two randomised trials have assessed the effect of weight-based low-molecular-weight heparin dosing vs. fixed dose in trauma patients. These pilot studies did not demonstrate a statistical difference between groups although there was a trend in favour of a lower incidence of deep vein thromboses with the increased dose low-molecular-weight heparin prophylaxis. However, both studies included non-severe trauma patients and the second study focused only on deep vein thromboses. Other studies suggested that a superior-than-standard dose of low-molecular-weight heparin, sometimes\n\nguided by the anti-Xa activity, decreases the incidence of venous thromboembolism in severe trauma without increasing bleeding events, but they were observational in nature.\n\nThe hypothesis of the HEPTRAUMA trial is that, in severe trauma patients, a thromboprophylaxis with intermediate dose low-molecular-weight heparin (twice the standard dose) decreases the incidence of major venous thromboembolism compared to standard dose.",[26,27],"Severe Trauma Patient","Venous Thromboembolism",[29,30,31],"Thromboprophylaxis","Severe trauma","Anticoagulant","NOT_YET_RECRUITING","2026-04-23",{"date":35,"type":36},"2026-04-29","ACTUAL",{"date":38,"type":20},"2026-04",{"date":40,"type":20},"2028-05",{"name":42,"class":43},"University Hospital, Grenoble","OTHER",17]
