After cerebral hemorrhage, people who open their eyes but have no conscious response to external stimuli for more than 3 months are called vegetative state or prolonged coma, which can be stimulated to recover potential by means of hyperbaric oxygen and electrical nerve stimulation therapy. After cerebral hemorrhage, long-term prolonged coma may result due to necrosis of brain tissue and neurological damage caused by hematoma compression. After the deep coma has passed, there may be instinctive spontaneous eye opening, aimless eye movements, and a state of seeming to be asleep or not, but lack of purposeful movements, inability to actively adjust the body position, and lack of active solicitation for food. For prolonged coma, it can be treated with drugs such as cytarabine and neuroglycosides, hyperbaric oxygen therapy to relieve cerebral hypoxia and activation of brainstem reticular activating system. In addition, neuroelectric stimulation therapy can also stimulate the resuscitation potential and increase the possibility of resuscitation. The above medications should be used under the guidance of the clinician, and unauthorized use of medications is prohibited. Hyperbaric oxygen, electrical nerve stimulation and other therapeutic measures should be administered by a clinician.
