Medical explanation:
Prevention of VTE mainly refers to the prevention of deep vein thrombosis or pulmonary embolism in medicine, because VTE, that is, venous thromboembolism, including deep vein thrombosis and pulmonary embolism, is the third most common cardiovascular disease after ischemic heart disease and stroke.
Symptoms:
Clinically, VTE occurs in different places and to different degrees, including superficial venous thrombosis and deep venous thrombosis of lower limbs. Especially deep venous thrombosis, if it is not well prevented in the acute stage, it is easy to have pulmonary embolism.
Mild people will cause chest tightness, shortness of breath, chest pain, hemoptysis and other symptoms, and severe people will have fatal pulmonary embolism. Therefore, patients with vte risk or even VTE must be well prevented and treated.
Preventive measures:
The most common causes of VTE in clinic include surgical trauma, tumor and immune system diseases. Therefore, before the occurrence of VTE, it is necessary to carry out good prevention and education for the above-mentioned people to prevent unnecessary occurrence. In daily clinical work, patients are advised to rest and exercise properly.
At the same time, patients who stay in bed for a long time should raise their limbs and give proper bed exercise to prevent congestion and avoid the formation of deep vein thrombosis. Once deep venous thrombosis occurs, it is recommended to stay in bed and avoid activities to prevent the thrombus from falling off and causing fatal pulmonary embolism.
Contraindications and precautions of VTE drug prevention;
Taboo:
High-risk patients with venous thromboembolism are mainly prevented by blood anticoagulation and muscle pump contraction, because the occurrence of venous thromboembolism is closely related to vascular injury, hypercoagulability and blood flow stagnation. It is suggested to actively prevent high-risk patients with venous thromboembolism, and formal preventive measures can effectively prevent high-risk occurrence.
Contraindications are mainly the above-mentioned situations, mainly because anticoagulation treatment for patients with the above-mentioned situations is easy to aggravate the risk of bleeding, causing intracranial hemorrhage and visceral hemorrhage.
Precautions:
The precautions for drug prevention of venous thromboembolism are to confirm whether patients have contraindications to anticoagulation before taking drugs, and to take enough anticoagulants regularly for a course of treatment. The duration of drug use is determined by the risk of venous thromboembolism. In addition, patients need to pay attention to rest during medication, avoid fatigue, have a light diet, have a balanced nutrition, and see a doctor in time if they feel unwell.
