How long it takes to be discharged from the hospital after subarachnoid hemorrhage surgery cannot be generalized, as different conditions and diseases require different lengths of treatment. If the patient was conscious before the operation and has good consciousness after the operation, the hospitalization may be relatively short, such as 2-3 weeks. If the patient is comatose before the operation, he or she may be comatose for a longer period of time after the operation, and even some patients need to have a tracheotomy, and some tricky complications will occur, such as lung infection, upper gastrointestinal bleeding, and deep vein thrombosis, and this kind of patient will have a relatively longer discharge time.
