There is no authoritative data on the probability of safely passing the dangerous period of cerebral edema, which is mainly related to the size of intracranial lesions, the amount of bleeding and the treatment.
1. The size of intracranial lesions: there are many causes of cerebral edema in clinic, intracranial lesions, especially occupational lesions, can lead to cerebral edema, timely surgical resection, generally about 7 days cerebral edema can gradually disappear.
2. The amount of bleeding: if the amount of bleeding is less than 30 ml, the danger period is about 7 days, during which the brain hernia may occur and endanger the life; after the danger period, the vital signs are relatively stable. If the amount of brain hemorrhage is more than 30 milliliters, the risk period is about two weeks, and cardiac arrhythmia may occur and endanger life.
3. Treatment: When cerebral edema occurs, treatment is actively given, and mannitol is used for infusion. When there is bleeding, surgery can be carried out as early as possible, and decompression of the bone valve can make the patient get through the dangerous period as early as possible.
As for the time to pass the dangerous period of cerebral edema, it is recommended to consult the doctors of neurology department in regular hospitals.
