Patients in a coma from a cerebral infarction wake up after a week at the earliest, and some patients wake up within two weeks, or within a month. For patients with cerebral infarction to appear in coma, it is mainly seen in patients with severe large infarcts, and patients with large cerebral infarcts can develop cerebral edema and increased intracranial pressure. The appearance of cerebral edema usually starts on the second day after the onset of the disease, and the aggravation period of cerebral edema is on the fourth to fifth day, and the cerebral edema gradually subsides on the seventh day, and the cerebral edema disappears completely within two weeks. For patients with cerebral infarction, if cerebral edema appears, the patient’s condition will be aggravated, and the patient’s condition will be aggravated on the 4th-5th day, and the degree of coma should be gradually aggravated, and the cerebral edema will begin to subside on the 7th day, and the patient’s condition may be gradually reduced, and the degree of coma may be gradually reduced, and the patient may begin to wake up after the 7th day. For patients with cerebral edema, it usually disappears completely by the second week, so the patient is fully awake within two weeks. For patients with cerebral infarction, if coma occurs, brain treatment should be given promptly, and the commonly used drugs are brain-awakening drugs.
