Difference between brain death and coma: organ donation for brain death person

Brain death and coma are scientifically two completely different processes!

It is usually wrongly assumed that a brain-dead person has a chance of recovery, such as a person who has been in a coma. If you've heard that a person has suffered brain death and then recovered, it hasn't actually been brain death. Patients who have recovered are in fact in a deep coma, and after returning from a coma, their relatives or sometimes even some doctors and nurses who do not have enough information about the difference between brain death and coma have made such a misconception!

Therefore, sometimes relatives of a brain dead person mistakenly assume that he has a chance of recovery and return, so they do not consent to organ donation in the hope of recovery.

In a coma, there is a chance for some patients to recover, while brain death is, in medical terms, absolute death, and the person will never alive.

In brain death, the patient's recovery is impossible and his death within a few days is inevitable. Therefore, the opportunity to donate a brain-dead person's organ is limited to a few days!

Coma recognition

Cortical cells are highly sensitive to hypoxia, so when blood flow to these cells is stopped, they quickly become seriously and sometimes irreversibly damaged.  In this case, the person quickly loses consciousness and, depending on the extent of damage to the cerebral cortex, his reactions to environmental stimuli are reduced.  However, there is still the possibility of improving the condition and returning the consciousness of the disease that has gone into a coma.

Recognizing brain death

Brain death is the cessation of all brain activity and brainstem at the same time. a person with brain death is actually a person who, due to extensive brain damage, has been unable to communicate with his surroundings, cannot speak, does not see, does not respond to painful stimulations. A person with brain death is also unable to breathe spontaneously. Although he has a heartbeat, he has no recordable waves when we record his brain waves. His heart rate continues with the help of a ventilator and maintenance measures to keep donated organs in optimal conditions for transplantation. Brain death in medical science is absolute death and this person will never come back to life.

The need to create a culture for organ donation

Brain death :

In brain death, blood flow to the brain is stopped, oxygen is not supplied to it. The brain loses all its function and suffers irreversible damage.  Although other organs, including the heart, liver, and kidneys, are still functioning after brain death, they will gradually decline over the next few days.  The brain dead patient does not speak, does not see, does not respond to any external stimuli, and will not be able to breathe without the use of a ventilator.

The need to create a culture for organ donation:

Every day, several people in the country die due to the lack of transplanted organs. Meanwhile, every year, a large number of brain death cases (without organ donation) occur in the country!

The difference between brain death and coma and plant life

In this video, the difference between brain death and similar states of coma and plant life is compared.  Unlike a coma, there is no way for a person who has died of brain death due to brain death to recover.  Therefore, with the timely consent of the relatives of the brain dead person to donate his/her organs, the lives of several people can be saved.  But in a coma, organ donation does not make sense because the brain has not died and can return.  The symptoms of these two conditions are different and can be easily distinguished by specialist doctors.  Unfortunately, many relatives of the brain dead person due to lack of necessary knowledge think that their loved one will return like a comatose person, but it is a misconception!  Due to the toxins caused by brain death, in a few weeks, the complete death of the person will lead to brain death, and if they do not agree to donate an organ, the lives of needy patients will not be saved from death!

هر فردی که دچار مرگ مغزی می‌شود، می‌تواند هشت نفر را احیا کند.

هر فردی که دچار مرگ مغزی می‌شود، می‌تواند هشت نفر را احیا کند. در تصادفات مرگ مغزی، ریه اولین عضوی است که از بین می‌رود و پیوند ریه تخصص خاصی لازم دارد اما باقی اعضای بدن اعم از قلب، کلیه، کبد و... قابل پیوند است. پیوند اعضا تنها راه ادامه حیات برای بیماران مبتلا به نارسایی پیشرفته قلب، کبد و... است.

در حال حاشضر بیش از یک میلیون نفر در جهان از درمان پیوند عضو بهره مند هستند و بقای تعدادی از این بیماران به بیش از ۲۵ سال رسیده است. در این میان، مدت طلایی برای پیوند عضو تنها چند روز است، مساله ای که با گرفتن رضایت اهدای عضو از خانواده‌هایی که بیمار مرگ مغزی شده آنها کارت اهدای عضو ندارد، برای اعضای هماهنگ‌کننده اهدای عضو مشکل است. بسیاری از مواقع خانواده‌ها به راحتی به اهدای عضو فرد رضایت نمی‌دهند و فرایند رضایت گرفتن از آنها گاهی تا چهار روز طول می‌کشد که در این زمان وقت طلایی برای اهدای برخی اعضای حیاتی از جمله ریه از بین می‌رود. اهدای عضو یک مقوله چندوجهی است که برای بهبود فرهنگ در این زمینه نیاز است که افراد و سازمان های مختلفی ورود پیدا کنند. برای فرهنگسازی در زمینه اهدای عضو، مسئولان، سازمان های مردم نهاد، خیران، هنرمندان و سایر افراد تاثیرگذار در جامعه نقش مهمی دارند. 

کارت اهدای عضو که افراد برای گرفتن آن اقدام می کنند به هیچ عنوان وجه قانونی و حقوقی ندارد و در ایران رضایت اولیای دم است که اهدای اعضای فرد مرگ مغزی را تعیین می‌کند. اما تجربه ثابت کرده است که بعد از مرگ مغزی شدن فرد، زمانی که کارت اهدای عضو او به خانواده اش نشان داده می شود، خانواده حتما به خواسته او عمل خواهند کرد. در کشور ما وزارت بهداشت اقدام به راه اندازی سایت کشوری اهدای عضو با آدرس  www.ehdacenter.ir  کرده است تا زمینه‌ای را به وجود آورد که افراد علاقه‌مند به گرفتن کارت اهدای عضو به راحتی و با پر کردن فرم اینترنتی بتوانند کارت اهدای عضو دریافت کنند. پس از پر کردن فرم اینترنتی کارت اهدای عضو بالا می‌آید و افراد می‌توانند با گرفتن یک پرینت از آن، این کارت را همراه خود داشته باشند بدون این که نیازی به مراجعه به اداره خاصی باشد.
