A vegetative person has no awareness of self or the external environment, and therefore a vegetative person has no sense of pain. A vegetative person, also known as a vegetative state, or unresponsive arousal syndrome, is a patient who has suffered a variety of severe brain injuries that have caused him or her to move from a coma to an aroused state of unconsciousness. The patient’s main manifestations are: no conscious activity, inability to carry out commands, typical symptoms of lack of cognitive ability, inability to understand and express language, no response to pain stimuli or the existence of a slight response, limbs may be unconscious random movement, incontinence, but the brainstem reflexes exist, and the ability to maintain voluntary respiration and blood pressure. As the vegetative person remains bedridden for a long period of time, complications such as muscle atrophy, bedsores and infections may occur. After active treatment, a few patients may regain consciousness and resume normal life. It is recommended that treatment be carried out under the guidance of a professional doctor. After active treatment, patients may regain consciousness and even return to a normal living condition.
