"U.S. scientists have managed to revive dead dogs to life, by using a technique similar to cryogenation, in which the dogs' blood was drained and replaced by a cold, saline liquid. A couple of hours, their blood was replaced, and an electric shock brought them back to life with no brain damage. The technology will be tested on humans within the next year."
Soon I will freeze myself and outlive you all
This has amazing potential, if the subject is brought back without brain damage then

This is a really interesting advancement. But you have to consider how long the dogs bodies were "frozen" If not more than a few hours than it's highly likely that there
wouldn't be any brain damage. And if this is the case than what would the effect be if the subject was "frozen" for a longer period of time?
Cryogenic freezing is already common for bacteria and other living cells, with great success. Unfortunately the body is infinitely more complex than these relatively simple organisms, and so there are some serious drawbacks to the process in human beings. For example, when the temperature passes -100C, water is forced out of the cells and crystallises, piercing the membrane and causing significant damage. As you freeze, there is a very real chance your tissues will tear due to differences in temperature between areas of the body. Alcor acknowledges these damages are unavoidable, and even provides a full list of theoretical dangers of the process on request. They express confidence, however, that the emerging science of nanotechnology will easily be able to repair you before you are brought back to life.
That is from a website (I couldn't get thelink to work)
Earlier in that same artical they stated that cryogenic freezing technically does not work. So seeing as how this procedure is essntually the same thing. It seems as though they might need to continue working on it.

If it's only for a couple hours as that blurb seems to say, would it even be useful at all? If it could lower the metabolism of some organs it could preserve them a little longer than they would normally for transplant purposes, but wouldn't it be easier to just remove them and cool them separately or keep the body hooked up to machines until it was time for the transplants?

Wow...this gives a whole new dimension for dogs playing dead.

Actually, it could be very useful.
For example, during certain types of neurosurgery, doctors have to chill the patient's body to a temperature that would normally result in life-threatening hypothermia in order to keep the nerves they're operating on for triggering things like twitches and thrashing.
The problem with the current method is that, while it aids the neurological side of it, the patient sometimes undergoes permanent tissue damage such as frostbite-like symptoms that result in the removal of extremities.
