In general, cerebral infarction in the elderly requires continuous infusion for at least 14 days. Cerebral infarction is a critical condition in neurology, and the acute period is usually 14 days, during which continuous infusion is required. During the acute period, the patient’s condition may deteriorate at any time, resulting in a life-threatening condition, and the subsequent need to continue the infusion is related to the patient’s condition. Cerebral infarction has many causes, and the main causes can be divided into three categories: cerebral thrombosis, cerebral embolism, and hemodynamic disorders. Once cerebral infarction occurs, irreversible damage to brain cells occurs, resulting in a series of abnormalities in movement, sensation, consciousness, and autonomic function. The treatment of cerebral infarction mainly aims to save the ischemic semidarkness zone, i.e. the ischemic but not yet completely infarcted area around the cerebral infarction, to prevent further deterioration of the condition and endangerment of life. If cerebral infarction is combined with other complications, such as lung or urinary tract infection, cerebral hemorrhage, etc., the treatment may need to be prolonged as prescribed by the doctor.
