After cerebral hemorrhage patients are at risk of rebleeding and will also develop cerebral edema and infection. After conservative treatment, it takes about 1 month for the condition to return to a stable state, but it is important to monitor changes in the condition during conservative treatment to see if conservative treatment is appropriate. For the first 3 days after brain hemorrhage, patients are at risk of rebleeding, and blood pressure can be controlled by medication to reduce the hypercoagulable state of blood. After that is the peak period of cerebral edema. Generally, after cerebral hemorrhage, edema gradually begins to form and usually remains for about 2 weeks, and through the application of drugs to lower intracranial pressure, the hematoma will gradually liquefy and absorb and the edema will slowly disappear. In addition, after a cerebral hemorrhage, the patient has paralysis of the limbs and impairment of consciousness, most of the patients will be bedridden and may develop lung infection, etc. The infection period after a cerebral hemorrhage may last for more than 2-3 weeks. So a conservative treatment for a brain hemorrhage will take about 1 month or so. After the conservative treatment of brain hemorrhage is stabilized, there is also a long-term process of rehabilitation of paralyzed limbs, and the treatment of rehabilitation may take more than 1 year. Usually, rehabilitation of limb function should be carried out as soon as possible after the brain hemorrhage is stabilized. The paralyzed limb of the patient will gradually improve after the rehabilitation treatment, and it is more likely to improve within 1 year. If it is more than 1 year, the paralysis of the limb may maintain the status quo and there will be no more significant changes.
