Brain hemorrhage is acute and critical, with high mortality and poor prognosis. Conservative medical treatment must comply with the following points: 1. Absolute bed rest, regardless of the amount of bleeding, must be all in bed for 24 hours, absolutely no bed activities. This is because the risk of rebleeding after cerebral hemorrhage is very high, and some patients may bleed again after activity even if the amount of bleeding is very small, which may endanger their lives. 2. prevent cerebral vasospasm, the probability of cerebral vasospasm in the first three days after cerebral hemorrhage is very high, and some patients may still appear after a week, and currently nimodipine (Nimoton) is commonly used in clinical practice to prevent cerebral vasospasm. 3. control excessive blood pressure. Most cerebral hemorrhages are caused by hypertension, and if the blood pressure is too high, the cerebral hemorrhage can be aggravated.4. Lower the intracranial pressure and control cerebral edema by applying mannitol intravenously every 6-8 hours.5. Give edaravone, oracetam and other nerve-nourishing drugs to promote the recovery of cerebral nerves.6. Diligently expel sputum to prevent the occurrence of pneumonic pneumonia.
