Résumé
Corona virus disease 2019 (COVID-19) patients with trauma are at high risk of venous thromboembolism (VTE), which must be taken seriously in the therapeutic processes. Hypercoagulable state is induced by 2019 novel coronavirus (2019-nCoV) in many ways, such as increasing the level of inflammatory factors and fibrinogen, and inducing endothelial cell injury. The venous wall injuries from trauma and operation directly or indirectly trigger off the exogenous coagulation pathway and the microcirculation can be damaged at the same time, which may initiate the exogenous pathway of VTE. Immobilization of limbs and forced bed rest during the treatment of traumatic patients will slow venous blood flow. Chronic non-communicable diseases such as diabetes in the elderly were independent risk factors for VTE. Furthermore, the persistent fever, severe lung disease, respiratory failure, sepsis and invasive technology application add the risk of VTE and the difficulty of treatment. In order to help effective prevention VTE of for COVID-19 patients with trauma, the authors put forward relevant technical suggestions for prevention and nursing of VTE to provide basis for nursing work during pandemic of COVID-19.
