The time for patients with cerebral infarction to be put on drip is related to the site of cerebral infarction, the size, the number, and the patient’s physical basic condition, which is generally 7 to 14 days. When acute cerebral infarction occurs, if the site is non-functional area, the infarction foci are small, the number is small, and the patient’s physical basic condition is good, the infusion is generally needed for 7 to 14 days. If the infarction site is the functional area of the brain, the infarction foci are large, the number is many, or the patient is combined with other organ complications, then longer treatment time is needed, and active rehabilitation exercises are carried out. Therefore, the number of days of infusion for infarct foci needs to be judged according to the severity of the patient’s condition. But in any case, cerebral infarction is a critical condition in neurology, which needs to actively cooperate with the physician’s treatment and follow the medical advice to avoid further deterioration or recurrence.
