After entering autumn and winter, some middle-aged and elderly people can always be seen in some primary hospitals to regularly inject traditional Chinese medicine injections such as Danshen and Chuanxiong, and many of them even take the initiative to ask doctors to prescribe these drugs in order to "dredge blood vessels" and prevent strokes. So, can infusion really prevent stroke? Du Wanliang, deputy director of the Neurology Center of Tiantan Hospital, said that regular infusion is completely unnecessary, which not only has no preventive effect, but also may bring additional risks.

In Tiantan Hospital, doctors often meet patients who take the initiative to prescribe traditional Chinese medicine injections with the effect of promoting blood circulation and removing blood stasis. "Whenever this happens, the doctor will definitely not be able to open it, and he will also give the patient science on the spot." Du Wanliang said that intravenous drugs for promoting blood circulation are short-acting drugs. When stroke patients have acute onset, intravenous medication can improve blood flow, slow down the progress of the disease and have therapeutic effect. However, these drugs have a short time in the body and do not have the effect of preventing the onset, so they should not be used at ordinary times. If you receive unnecessary infusion, it may bring additional risks, including drug allergy and infusion reaction.

Du Wanliang introduced that there are two main risk factors for stroke. The first category is hypertension, diabetes and other basic diseases. The second category is smoking, drinking, less physical activity and other behavioral risk factors. The prevention of stroke is a long-term work, and what really plays a preventive role is oral drugs. If you take the medicine regularly for a long time, the medicine will continue to play a role for 24 hours and play a preventive role.

"It should be noted that because each patient has different risk factors for stroke, the types of antithrombotic drugs that need to be taken are also different. If there is atherosclerosis or atherosclerotic stroke, doctors usually prescribe antiplatelet drugs such as aspirin and clopidogrel; If atrial fibrillation or cardiogenic stroke occurs, doctors usually recommend taking anticoagulants such as warfarin or dabigatran. "

Du Wanliang reminded that people with stroke risk factors or related medical history must return to the hospital for outpatient service regularly, and the doctor will adjust the drug type and dosage according to the change of the condition. He said that some outpatients with hypertension and hyperlipidemia often stop taking drugs after their physical indicators improve, which is incorrect. Because the relevant indicators will rebound and continue to cause harm after stopping the drug for a few days. In addition, when doctors visit patients, another important goal is to confirm whether drugs have side effects, which need to be discovered through face-to-face inquiry, observation and examination. Once a similar situation occurs, the doctor will adjust the dose or change the drug type in time. Therefore, patients should not think that seeing the clinic will be done once and for all.

"To prevent stroke, it is more important to change lifestyle." Du Wanliang said that in daily life, people with behavioral risk factors should quit smoking and limit alcohol, strengthen exercise, eat reasonably and establish a healthy and scientific lifestyle. In addition, people should have regular physical examinations. Physical examination can find some potential health problems in advance, such as borderline hypertension and diabetes. At the same time, the physical examination report also contains body mass index and information of various organs of the whole body; It is recommended that people over 40 have a routine physical examination every year.
