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

how long does it take to wake up from coma after subarachnoid hemorrhage? we have to deal with this according to different situations.

because subarachnoid hemorrhage can occur spontaneously or traumatically.

1. traumatic subarachnoid hemorrhage: mainly manifests as bleeding within the sulcus on the surface of the brain.spontaneous bleeding originates from intracranial aneurysm. the duration of coma due to aneurysm bleeding is related to the amount of bleeding. those with a small amount of bleeding may be in coma for a short time. if the amount of bleeding is large and the aneurysm is not surgically clipped or intervened in time, the bleeding is more likely to continue. the coma time will be longer, which is related to the amount of bleeding or whether the aneurysm has been treated. the traumatic nature needs to be judged based on the performance of brain contusion, the extent of the injury, the presence of subdural hematoma, the presence of epidural hematoma, and the presence of skull fracture. traumatic subarachnoid hemorrhage is generally an accompanying pathological change of other diseases and needs to be combined with the conditions of the primary disease.

2. spontaneous subarachnoid hemorrhage: often caused by rupture of a cerebral aneurysm, this type of bleeding is usually serious, and is often followed by other neurological dysfunctions. patients can experience short-term coma after hemorrhage, no coma at all, or severe coma after hemorrhage. the coma can last for days, weeks, or even in a long-term vegetative state. most patients with spontaneous subarachnoid hemorrhage may have a very severe headache after the hemorrhage, and some patients may experience temporary unconsciousness. if the aneurysm is treated effectively and promptly, the patient can regain consciousness in 1-2 days or 3-5 days;

3. some severe and extremely severe aneurysmal subarachnoid hemorrhage: the patient's coma time may reach 2-3 weeks or even longer. there are also some patients with very severe subarachnoid hemorrhage who may be in a coma for a long time and find it difficult to effectively regain consciousness.
