Cerebral infarction is fully known as cerebral infarction, the number of days of infusion treatment is decided according to the severity of the patient’s condition, and there are individual differences in the specific time, usually in about 2 weeks time. The main purpose of treatment is to protect the nerves, reduce the cranial pressure and improve the circulation. 1. Protecting nerves: mainly edaravone, cytidine diphosphate, protein hydrolysate and piracetam, etc., which are for the treatment of cell injury after acute ischemia or reperfusion, and can protect the brain cells and improve the tolerance to ischemia and hypoxia. 2. Reducing cranial pressure: mainly mannitol or glycerol fructose and other drugs, cranial pressure reduction therapy is mainly applicable to people with cerebral edema and increased intracranial pressure, seen in large cerebral infarction, patients with cerebral edema and increased intracranial pressure began to appear on the second day after the onset of the disease, and began to reduce after one week, and two weeks gradually returned to normal. 3. Improvement of circulation: there are main drugs such as butylphthalide, ginkgo biloba extract, etc., which can improve the circulation and promote the recovery of neurological function. The acute period of cerebral infarction is 2 weeks, so the infusion treatment of cerebral infarction is usually about 2 weeks, and the light cases can be short, within 1 week, and the heavy cases can be relatively long. After cerebral infarction infusion drugs and time, listen to the attending physician arrangements, do not blindly self-judgment.
