Brain death includes whole brain death including brainstem. A brain-dead person has no voluntary breathing and heartbeat, while the brainstem is still functional in the vegetative state, and as long as sufficient nutrition is input into the body, the organism can digest and absorb it, although the organism is no longer conscious, perceptive, or thinking. The most intuitive judgment is that the EEG is a straight line when the brain is dead, while the vegetative state can have some scattered waveforms. In recent years, China has adopted more methods than foreign countries for the treatment of “vegetative state”, such as cerebellar parietal nucleus electrical stimulation, high cervical medullary electrical stimulation, peripheral nerve electrical stimulation; sound, light, electricity, magnetic stimulation; hyperbaric oxygen, extracorporeal counterpulsation, Chinese and Western medicine, acupuncture, massage, etc. However, most of them wake up after many years. However, the vast majority of those who wake up after many years are often not true ‘vegetative patients’, but patients with atresia syndrome or patients with minimal consciousness. These two types of patients look very similar to ‘vegetative’ people from the surface. In fact, patients with atresia syndrome are not able to speak, swallow, or move, but they are actually conscious. Patients in the minimally conscious state are slightly less ill than ‘vegetative’ patients and have a relatively higher chance of recovery. There are no animal experiments and rigorous clinical comparative studies on the rate of wakefulness in China, so it is impossible to tell how big the difference is. Can the treatment level be lowered for “vegetative patients” who are not likely to revive and whose condition is stable? Can we abandon the treatment or even “euthanasia” for “vegetative patients” who are not likely to wake up and are in serious condition? Our law does not say anything at present. Some people suggest: according to our patient’s vegetative state diagnosis standards, according to our national conditions, “vegetative person” that lasts for more than two years can give up the promotion of waking treatment or terminate the treatment.
