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. Generally, the course of intravenous infusion for acute cerebral infarction is about 1-2 weeks. If the onset of acute cerebral infarction is within 4.5 hours, intravenous thrombolysis with alteplase can be given, and the dosage of alteplase is 0.9 mg per kilogram of body weight, which costs about 6000 yuan, together with neurotrophic drugs such as cytarabine and olanzapine, oxygen radical scavenging drugs such as edaravone, drugs to improve cerebral collateral circulation drugs such as eurycomycin and butalbital, and drugs to improve cerebral circulation such as herbal injections of Ginkgo biloba, the cost of treatment is about 15,000 yuan. If severe stenosis of the responsible blood vessel exists within 24 hours of onset, mechanical embolization is considered necessary, and the cost of embolization ranges from several tens of thousands of dollars; if the onset of the disease has exceeded 24 hours, only antiplatelet or anticoagulation therapy, circulation improvement, neurotrophic and cerebral protective drugs are generally required, and the cost is relatively small.
