Can brain death still be restored, and after brain death, is the body still alive .

Brain dead does not change in vegetative state. Brain death cannot be recovered. Vegetative people can (strictly called promising).

To put it simply, a vegetative person can breathe on his own, and a brain dead person can only be ventilated.

Brain death is an irreversible state of loss of skills throughout the brain, including the brainstem.

Prerequisites include: clear cause of coma, exclusion of reversible coma of various causes.

Diagnostic criteria: deep coma, complete loss of brainstem reflexes, no spontaneous breathing. All of the above must be present.

In the confirmatory test, the EEG was straight, the transcranial Doppler ultrasound showed a pattern of brain death, and the waveform of somatosensory evoked potentials above p14 disappeared. Must be positive in one of these three items.

Vegetative: The function of the cerebral cortex is severely impaired, and the victim is in an irreversible deep coma, losing consciousness, but the subcortical center can maintain spontaneous breathing movements and heartbeats, this state is called "vegetative state", and patients in this state are called "vegetative people".

Yes, as long as it can revive its brain cells.

After brain death, because the heart is still alive, it can maintain blood for a short time**, but without the regulation of the brain, breathing may stop, so that a series of symptoms such as lack of oxygen in the body will appear, and the body will soon die. Moreover, the brain is the "headquarters" that governs the human body and is the "soul" of the person, so brain death is equivalent to human death.

It is clear that whether a person is alive or not depends mainly on whether he still has a heartbeat and breathing. Now, with the help of ventilators, blood pressure-raising hormones, and hormones, brain-dead patients can theoretically keep their bodies running for a long time. Brain-dead patients are becoming more and more fragile and the risk of tissue infection is high.

Brain death cannot be resurrected.

After brain death, it will not come back to life, but this diagnosis of "brain death" should be absolutely correct. If the diagnosis is wrong, there is a chance that the person will come back to life. There is a strict procedure for declaring brain death, and there are many tests to be carried out, and after the declaration, it is necessary to wait 12 hours for confirmation.

Notice that each of those tests is essential. It is not a miracle that a person who has been declared dead has come back to life, it is a misdiagnosis by a doctor.

After brain death, the electrical potential in the heart can keep the organs active for a short period of time, and in fact the heart can beat outside the body. But without a ventilator to keep blood and oxygen flowing, the heart stops beating for a short time. When a ventilator is present, some biological processes including the kidneys and stomach can sustain working for a week.

After brain death, the body will no longer secrete important hormones to maintain some physiological functions, including stomach, kidney, and immune function, and they will not function for more than a week. For example, thyroid hormone regulates the body's metabolism, and antidiuretic hormone keeps the kidneys hydrated.

Nerve cell death is non-renewable, neuronal cells are permanent, and cell regeneration is unlikely, but the necrotic site of normal cells produces many synapses, which are interconnected and better for the functional compensation of the necrotic site. These fibroblasts do not have the functions of neuronal cells, but they have good electrical conductivity. Since there is no hope for nerve cells to regenerate, it is very important to protect brain cells for human health, especially to prevent the effects of cerebrovascular accidents and brain damage on brain cells.

Prevention of cerebrovascular accident and cerebral atrophy plays a very important role in protecting brain cells. With the exception of the olfactory and optic nerves, which are formed by protrusion of the ventricular wall during the embryonic stage, the other cranial nerves are similar in their developmental form to the spinal nerves. Cranial nerves can be divided into sensory nerves; Motor; Neuro promiscuity.

The sensory and optic nerves are connected to the telencephalon and diencephalon, respectively, and the rest are connected to the brainstem. Usually a large number of brain nerve cells die, then it will generally cause brain function damage, or even damage, and a series of diseases will appear accordingly, if there is no other inflammation or disease, then the general life expectancy is about 5 to 10 years, during which time also needs to be taken in time.

Brain cell death can lead to signs of neurological dysfunction in patients. Brain cell death is irreversible. Compression, mass effect, ischemia, hypoxia, trauma, and inflammation can all lead to brain cell death.

Patients will have corresponding symptoms of neurological deficits, and the symptoms vary from site to site. Hemiplegia of the contralateral limb occurs when brain cells from the basal ganglia of the cerebral hemisphere die. If it is in the internal capsule, there will be a typical tripartite sign, including hemiplegia, hemiplopia, and hemiplegia.

If cerebellar brain cells die, dizziness, ataxia, unsteadiness in walking, nystagmus, and slurred speech can occur.

If it is a brainstem location, quadriplegia, high fever, coma, and severe impairment of consciousness will occur. If it is the surface layer of the cerebral cortex, symptoms such as epilepsy, mental disorders, memory impairment, etc., may occur. To avoid pulmonary sputum and bronchopneumonia, turnover, back patting, and limb movement should be strengthened to prevent inferior vena cava thrombosis and bedsores.

Pay attention to nutrition as well. The patient's gastrointestinal function is not particularly good. It is also necessary to pay attention to bowel movements, balance the dietary structure, dietary fiber, energy-providing substances and proteins.

In general, it is impossible to regenerate under natural circumstances, unless some special drugs are used to regenerate cranial nerves.

If the human cranial nerve is damaged, it takes at least three months to half a year to repair, and it is impossible for human nerve cells to regenerate once they die, but the damage of nerve cells may be gradually repaired. Nerve damage may be divided into axonal degeneration, necrosis, and demyelination. If it is a demyelinating change, it may be more effective to improve circulation and dilate blood vessels through nourishing nerves.

No, because after the death of the cranial nerves, they cannot be regenerated, and it is already difficult to survive, so they cannot be regenerated.

In life, the focal eye radar absorbs the image. A backlog of bochromatic images between the brain and the heart. Generate new neural pairings,

No, it won't. Brain cells do not regenerate after death, and brain cells are nerve cells, which are non-reproducible, so after brain cells die, there will be permanent residual lesions on imaging, which may lead to the existence of sequelae in patients.

Generally, there is little chance of survival, but there is no way to wait for a miracle.

Hard, I hope she can wake up.

1. The most difficult thing to rescue and treat in a car accident is the head, the next ten days, will be a period of high incidence of edema, if your friend can survive the more than ten days, if you can restore spontaneous breathing, then life can be basically saved.

2. If he continues to be in a coma, and spontaneous breathing cannot be restored, and the brain stem has no response, then he will enter a state of brain death (vegetative).

3. The brain and the heart are two different organs, if the brain is dead, the heart will continue to beat without lack of oxygen, and at this time, the signs of life can be maintained with instruments and drugs until the heart or lung fails. How long you can live depends on the patient's age and physical condition.

4. If your friend is a young person and his family believes in religion and culture, it is recommended that his family quickly find a folk master and psychic person, go to the scene of the car accident to collect the soul, do things, put incense, Sometimes, some things are very evil, and science and medicine cannot solve the things, through those, it can be solved (for reference only).
