Anesthesia, coma, brain death, and vegetative life

Anesthesia, coma, brain death, and vegetative life are different levels of consciousness that occur in patients’ specific conditions.

Awareness is primarily about the time, place, and people around. The person who falls in the level of consciousness may lose consciousness for only a few moments, or that for hours, days, even weeks and months in this case Stay.

Syncope is a temporary loss of consciousness that usually lasts no more than a few seconds to a few minutes. The reason for this is the temporary cessation of blood flow to the brain. Upon returning the bloodstream to the brain, the level of consciousness and brain function return to normal.

But there are also situations in which the level of consciousness remains disturbed for a longer time, among which coma, brain death and vegetative state are more famous than the rest.

What is coma?

Kama is a condition in which the patient loses his consciousness to a large extent and is no longer able to respond to external stimuli. In this case, the patient can not communicate in any way with the outside environment. Coma accompanied by a widespread brain injury or damage to parts of the brain stem that is responsible for keeping alertness.

Reasons for coma:

In fact, more than 50% of people who go to coma are affected by head injury and impaired brain circulation. But poisoning can lead to excessive consumption of alcohol, diabetes, increased intracranial pressure, increased blood urea, morphine, and excess bleeding.

Often patients who go to coma after an incident, after leaving the coma, they have difficulty breathing in the upper airway and are unable to speak correctly. In some cases, after a patient’s intelligence, retraining and remembering a lot of things, including speaking and remembering yourself, may be necessary.

What is vegetable life?

Vegetative life or apical syndrome is a condition in which a person has open eyes and occasionally involuntarily moves his body. However, in response to environmental stimuli, no response is seen in the patient.

Functions such as heart rate, respiration, blood pressure, etc., known in the medical term as autologous or autonomous functions of the body, are common in this person, but he has no particular brain activity. The patient does not make any significant relation with the outside environment and the surrounding people.

Vegetable life may last for years or even decades. If this situation lasts for more than a month, it is said to be a stable vegetable condition, which can almost be said to be very poorly reversed. However, there have been many cases that, even months after the occurrence of this situation, have returned to normal with care and proper care. Vegetative life occurs in almost all cases following deep depression and cerebral cortical damage

What is brain death?

In brain death, blood flow to the brain is stopped and oxygen does not occur. The brain loses its entire function and suffers irreversible damage

However, after brain death, other organs such as the heart, liver and kidneys are still functional, but gradually fail in the next few days.

A brain death patient does not respond to any external stimulus. His limbs are loose, do not blink, do not speak, do not see, and there is no evidence of electronic brain function in the brain barrier and will not be able to breathe without the use of artificial respiration.

Difference in coma with brain death:

It is actually a disorder in the functioning of the brain that a person suffers from a severe reduction in the level of consciousness and does not respond to any of the stimuli around him. In coma, there is a chance of recovery for some patients, if in brain death, it’s impossible to recover and death within a few days.

Difference in vegetable life with coma:

Vegetative life status can be much more severe than coma, because these patients, although they show involuntary movements, do not show any signs of consciousness over time. In coma, there is a chance of recovery for some patients.

Individuals awake from coma in vegetable life and, like normal people, go through sleep and awakening cycles, but they do not gain consciousness. These patients turn around and on the wake of their waking hours, and most of them retaliate, such as laughing, crying, swallowing, and even squeezing hands from others.
