I wrote the following as an article for CRYONICS Magazine in 1996 while still President of Alcor. This is based on conversations several cryonicists, including myself, have had with people in the transplant field. Others, such as Steve Harris, M.D., may have more precise answers, but this should do for a starting point. ********** CAN CRYONICISTS BE ORGAN DONORS? By Steve Bridge June 13, 1996 About once a week I am asked if a cryonicist, especially one who has chosen neurosuspension, can also donate organs for transplant. The answer is a qualified "No." There are several barriers, any one of which makes post-mortem organ donation impossible for cryonics patients. 1. Alcor's ability to provide reasonable preservation for a member's brain is strongly dependent on how fast our transport team can begin cooling the member and adding protective chemicals. Forcing Alcor to wait several hours while surgeons remove a heart and kidneys is not good for your brain. We assume you are involved in cryonics at all because you want your brain treated with utmost care. 2. All states require evidence of "brain death" before a hospital can remove organs from a donor. "Brain death" typically means that the brain has had no circulation for 24 hours (not at all good for your brain) or has been obviously destroyed by injury. You don't want to wait for brain death before we freeze you. Your brain is you. 3. Even if you have chosen the neurosuspension option, Alcor's surgical team needs an intact vascular system, including the heart, to get cryoprotectants to the cells of your brain. Removing organs puts holes in that system. 4. From the hospital's point of view, they don't want organs that have had our solutions pumped through them, even though these solutions may be very protective. It would require hundreds of millions of dollars for research to prove that our particular combination of chemicals was safe and effective for transplants. It's not worth that. Donations you CAN make Many prospective cryonicists wish to contribute something to the health of others and feel uneasy about not donating organs. You can still help save many lives without causing problems for your suspension. You can donate while you are alive. I don't mean just giving a kidney to a relative, either, although that might very rarely be possible. There is at least one organ donation nearly all of us can make -- blood. Donating blood is simple, can help save many lives, and can even be healthy for you. Yes, recent research appears to show that men who donate blood at least three times per year increase their average life-span to that of women. The most plausible theory for this is that iron accumulation in the blood is a primary cause of cardiovascular disease, and women have their own natural method of discarding iron -- every month when they menstruate. I hope none of our readers believe the idiotic, backwards folklore that donating blood can place you at risk for getting AIDS. Many people in the 1980's got AIDS from receiving blood transfusions; no one gets AIDS from giving blood. (Detailed testing of blood today makes it extremely unlikely for a person to be infected with AIDS even by receiving a transfusion.) If you are in a serious accident, you certainly want other people in the community to have donated blood to save your life. It is only fair to put your share into the community pool to save other people's lives. Look in the Yellow Pages under "Blood Banks." When you donate your blood, you could also add yourself to the list for bone marrow donation. Thousands of people per year, especially with certain forms of leukemia, could have their lives saved by a donation of bone marrow from a tissue-compatible individual. Finding the level of compatibility required (near 100% for certain antigens) can be like searching for the proverbial needle in a haystack. Right now several million people have their antigen signatures listed in the National Marrow Donor Program (NMDP) data base; but every year many people die without finding a match. Antigen matching is especially difficult in the United States, with the nearly infinite mix of racial and cultural backgrounds of our residents. Adding your name to the NMDP Register could save a life. Making this effort as widespread as possible could also give you a chance at more life someday, should you be the one who gets the leukemia. To find out more about bone marrow donation, visit your local blood bank or call the NMDA at 1-800-627-7692. Cryonics is a way of saving your own life. It is selfish -- and I mean that in a good way. Understanding your own self interest is essential for survival. Being selfish does not also mean that you can or should abandon your family and community. Doing good for each other makes all of our lives better and contributes to our own individual survival. ********* I will also add to this article that, while it might be possible for the transplant team to remove organs and perfuse them, that would leave the cryonics team with a currently impossible job to properly protect your brain. Attempts thus far to learn techniques which would allow us, for instance, to perfuse the brain *rapidly* via the veins and arteries of the neck have not gone well. We really need a more intact circulatory system. Rapid perfusion of the brain after the head has been separated from the body does not appear doable by *any* surgeon today -- although it is certainly true that not many neurosurgeons are spending sleepless nights worrying about it. The most important point here is: as cryonicists our primary goal is to do what is best for OUR patients' brains. Any action which causes delay is not good. Give me a couple of billion dollars in research money and organ donations from cryonics patients might be a different story; but that money would best be spent in many other ways. For instance, Harvard this year made a breakthrough in the cloning of individual organs (largely unreported in the "Dolly" furor). *Eliminating the need* for cadaver organs altogether would be a much better use of those billions. Patients could get transplants from *themselves.* Steve Bridge Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=9139
