how many days will a coma last after cerebral hemorrhage?

patients with cerebral hemorrhage are generally comatose for 2-4 weeks and can gradually become conscious. continued lack of consciousness often indicates that they have entered a vegetative state or are in danger of life. patients often enter a coma after cerebral hemorrhage, which is related to the location and amount of bleeding. a hemorrhage volume of >50 ml in the cerebral hemisphere indicates large-scale cerebral hemorrhage. in areas of the brainstem such as the pons, midbrain, and medulla oblongata, even if the hemorrhage volume is 5-10 ml, the patient may enter a coma. affect the patient's state of consciousness and even cause coma.

cerebral edema increases significantly within 24-72 hours after coma, reaching its peak. with effective treatment within 1 week, the patient may gradually become conscious from coma. however, some patients did not fully recover within one month due to their extremely critical condition and could only maintain relatively stable vital signs, that is, they entered a vegetative state.(warm reminder: medical science sharing. this content does not represent face-to-face consultation. if you feel unwell, please seek medical treatment as soon as possible.)
