Patients with cerebral infarction should not be given infusions for more than two weeks at most. Patients with cerebral infarction need to be given drugs to improve circulation, nerve nutrition and brain protection after acute onset, and these drugs can be treated by intravenous infusion, because the acute period of cerebral infarction is about two weeks, so the course of infusion should not exceed two weeks at most. Even if further infusions are administered, it will not significantly help the patient’s condition. Of course, if the patient has lung infection or other serious complications, the course of infusion can be extended appropriately, depending on the patient’s specific situation. Patients should be gradually given oral medications for transitional treatment while infusion is in progress, and patients should be instructed to adhere to long-term secondary prevention medications to prevent recurrence of cerebral infarction.
