Once a sufficient level of assurance can be had that each patients' cause of death can be reversed, there wouldn't be much point in keeping them suspended. But that assurance may well require a great deal of experimental and clinical work. Who will provide their preserved bodies as test subjects for this work and accept the risks involved? So far I'm assuming the subjects who have been preserved wish to be revived, not experimented on. In pharmaceutical development there are "phases" of regulatory/legal test. I assume surgical or other medical techniques/technology may require similar phases of testing(?), or at least comparable numbers of test subjects (rarity of the disease permitting). "Phase 0" involves pure research: computer modeling, animal testing etc. Phase I trials are clinical trials involving small groups of patients to evaluate human safety (they may not even be ill - to guage effects/toxicity in healthy humans). (20+ people) Phases II->III increasing numbers of patients are given the drug to evaluate its efficacy. (>100 people) Phases III->IV is the passing into commercial distribution of a drug (Phase IV refers to safety monitoring after the drug hits the shelves). (1000+s of patients) Seeing as the drug administration bodies in the US and Europe demand proof of a drug's efficacy and safety based on trials involving thousands of subjects I do not find it that surprising that a medical procedure such as cryonics is not widely recognised by the medical profession. It's efficacy in terms of saving lives is at present a wholly imaginary number! Any thoughts? Anthony Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=26015
