اهدای زندگی Life Donation
به نام خدا، مطالبی راجع به اهدای عضو-اهدای سلولهای بنیادی-اهدای خون-اهدای پلاکت-اهدای پلاسما با همکاری کانون اهدای زندگی دانشگاه بناب--- آدرس صفحه اینستاگرام: ehda.zendeghi@Difference between blood donation and blood plasma donation - blood plasma applications
Plasma donation is done with the device, and only a yellow hatch is taken and the blood itself returns to the person, but the process for blood donation is in a way that blood completely enters blood bags. Of course, after blood donation, the same bag can be extracted, but the plasma volume with blood donation is one third of the plasma volume that can be taken independently by the device. Annually 500,000 liters of plasma are produced in the country, which produces 300,000 liters of private sector. The blood transfusion organization produces 200,000 liters of plasma from blood donated by people.
Plasma usage:
The obtained plasma is sent to plasma refinery centers for injection to patients or to produce specific pharmaceutical products derived from plasma.
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.
