A brain hemorrhage of 80mL is considered to be a relatively large amount of bleeding and a serious condition. For cerebral hemorrhage, if the amount of bleeding in the anterior circulation is 80mL, the patient is advised to undergo borehole drainage, or decompression by debridement, mainly to see if the cerebral hemorrhage breaks into the ventricles. If the patient also has severe headache, nausea and vomiting, it is considered that the intracranial pressure is relatively high and in severe cases the patient can develop brain herniation, which is life-threatening. For posterior circulation, bleeding in the brainstem or cerebellum is relatively serious. A cerebellar hemorrhage greater than 15 mL is recommended for surgery, while a brainstem hemorrhage of more than 5 mL is very dangerous. Brain hemorrhage of 80mL is very serious, and the patient is recommended to visit the hospital for immediate surgical treatment, and after surgery, the patient can be given dehydration and cranial pressure lowering treatment, and the condition can be stabilized with rehabilitation treatment.
