Deep vein thrombosis: refers to the abnormal blood coagulation in deep vein and block the lumen, cause vein circumfluence obstacle, is a common peripheral vascular disease, the body main vein all can come on, especially in lower limb veins.
Stroke patients (cerebrovascular disease collectively: mostly in cerebral infarction, transient ischemic attack, cerebral hemorrhage, subarachnoid hemorrhage) accompanied by more basic diseases such as hyperlipemia, hyperglycemia, hypertension, high blood viscosity, combined with the age is big, poor circulation. Drinking less water, long-term use of diuretics and other reasons to aggravate the high blood coagulation.
In patients with hemiplegia due to long bed blood stream is slow, muscle contraction, easily happened deep vein thrombosis of lower limb, and the incidence of lower limb venous thrombosis can be as high as 50%, and the heavier paralysis occurs, the greater the risk of deep vein thrombosis. If it is not taken seriously, it may lead to the aggravation of lower limb dysfunction, limb necrosis, and even severe pulmonary embolism, which may endanger life. Therefore, stroke patients with hemiplegia should prevent the formation of deep venous thrombosis of lower limbs!!
The second prevention.
1. Stop smoking: smoking cause vasospasm or contraction, blood flow resistance increases, so will cause the damage of blood vessel walls, further increases in blood viscosity, will accelerate atherosclerosis, each organ thrombosis.
2. Active control of primary diseases: hyperlipidemia, coronary heart disease and other diseases of the elderly have certain effects on blood vessels.
3. Protection of venous vessels: choose the large vein for puncture, which is light and skillful in operation, avoiding endometrial injury, avoiding repeated puncture, lower limb puncture and patient side puncture as far as possible. Use the iv trocar as much as possible. Avoid drugs that irritate blood vessels.
Active or passive exercise: the most important preventive measure. To maintain the function of the paralyzed limb, push up lower limbs of 20-30 °, so as to promote venous blood backflow. For patients with cerebral apoplexy with clear consciousness, assist in early bed movement of the affected limb. If the condition permits, get out of bed to increase muscle contractility and promote venous reflux. For coma patients, assist patients to carry out activities, and gradually increase the amount of activities, step by step.
5. Sole vein pump (pulse pressure instrument) is the principle of walking by simulating human physiology, through to the foot instant controllable pulse pressure, ensure high-speed venous reflux, thereby relieving blood stasis, the turbulence is formed after venous flap, stimulate the endothelial generate endogenous vasodilatation factors (EDRP), cannot let thrombus.
6. Regularly compare and observe the color, temperature, degree of swelling and normal feeling of patients' lower limbs.
7. Drink plenty of water: keep the body hydrated, reduce blood viscosity, promote blood circulation, and reduce the risk of thrombosis.
8. The food choice: choose light low fat food, eat more fruits and vegetables that are rich in vitamins, such as tomato, celery, black fungus, kelp, etc., these foods are beneficial to dilute the blood, prevent thrombosis.
