how long does it usually take to wake up from coma after brainstem hemorrhage?

brainstem hemorrhage is most commonly caused by rupture of the paramedian branch of the basilar artery, and hemorrhage is most common in the pons.

clinically, if the brainstem hemorrhage is >5 ml, it is called massive cerebral hemorrhage. the patient's brain tissue damage was relatively serious, the ascending reticular activating system was affected, and the vital center was affected. patients may experience coma, even decerebrate ankylosing, quadriplegia, high fever, limited eye movement, and stress ulcers.

patients will also have adjacent structures involved, such as the midbrain and ventricular system, and these corresponding symptoms and signs will often lead to poor prognosis and death. the time it takes for the patient to wake up after a coma due to brainstem hemorrhage depends on the amount of bleeding and the location of the bleeding.

if the brainstem ascending reticular activating system is significantly damaged, the patient's chance of awakening is relatively small. if the patient's bleeding volume is relatively small and close to the outside of the brainstem, after active treatment, the hematoma is absorbed, the cerebral edema is reduced, and there is no obvious pressure on the ventricles. the patient's condition will be stable after 2 weeks to 1 month, and he may gradually wake up. .

the duration of coma after brainstem hemorrhage varies depending on the patient's condition.
