Hi sorry for the condition of your brother. G B Pant is a superspeciality hospital with good neurosurgery setup. the recovery of the patient depends on the extent of neurological damage to the brain. if its an Extradural haematoma , evacuation of the same will lead to improvement . but other traumas like diffuse axonal injury , cervical spine injury , SDH , concussions have poor recovery and take very long time . private hospitals will provide almost the same treatment but the care will be more personalised. in coma patients recovery is unpredictable and can take very long time which will lead us to another fact of affordability. Also shifting of a comatosed patient will be associated with significant mortality. but all the big private hospitals like apollo, max , fortis can provide required care for your brother good luck dr Sanjukta
