The treatment of patients with acute cerebral infarction requires the establishment of intravenous channels for infusion therapy, and the drugs for intravenous infusion include intravenous thrombolytic drugs, neurotrophic drugs, cerebral protective drugs, and drugs to improve cerebral circulation. The general course of intravenous infusion for acute cerebral infarction is about 1-2 weeks, and the total treatment cost of intravenous infusion is about 10-15 thousand yuan. If the onset of acute cerebral infarction is within 4 and a half hours, patients need to be given intravenous thrombolysis with alteplase, the dosage of which is 0.9 mg per kilogram of body weight, and the cost is about 6,000 yuan, plus neurotrophic drugs such as cytarabine, vitamin B1, vitamin B12, cerebral protective drugs such as edaravone, eurefranil and drugs to improve cerebral circulation, such as Ginkgo biloba and other herbal Injections, the treatment cost is about 15,000 yuan.
