Ok, I may have my pet preserved with one of the cryonics organizations. I am in a very fragile state because my dog might be "expiring" very soon. My arrangements for him have been made. However, the organization I have signed up with is far away. I really need to hear some positives concerning if my dog dies quickly and I am not able to ask for heparin, ect. (or there are other complications). So if I have him straight frozen (besides the obvious fact that it is better than burial or cremation) is there a possibility (I am, of course, not asking for any guarantees here) that the damages from a straight freeze preservation can be reversed in the future? Please, I need to hear some positives. Thank you very much everyone for your time and feedback.

Straight freezing is a form of scrambling; none of the original matter is lost. Theoretically it can be reversed. The key question is how uniquely the original state can be determined. Does straight freezing leave a traceable record of the original state, or is a vast universe of possible starting conditions compatible with the final observed state? I don't know. There was a recent article in Cryonics magazine about how straight frozen tissue looks like hell in the frozen state, but then resumes looking much more normal after the ice melts. Strange.

Something like 30% of all cryonics cases are straight-frozen (frozen without cryoprotectant) because of the circumstances under which the patients clinically die. This underscores the idea that part of cryonics is not just about cryopreserving people under conditions where there is a solid argument for future reversibility, but also about cryopreserving people when there is large uncertainty about whether the revived person would be the original person at all. Survival after medical repair of serious neurological injuries will not be a black-or-white issue in the future.
