“…PE was reported at a rate of 18.6% in individuals who survived longer (Geerts et al, 1996). Patients over 45, a requirement of more than three days bed rest, a previous history of VTE, fractures of the lower extremity, pelvis, spine, the development of coma and plegia, a requirement for blood transfusion and surgery further increase the risk of DVT and PE, therefore, effective and safe prophylactic anticoagulant treatment is recommended in traumatic patients unless contraindicated (Shackford et al, 1990). …”
