There's also some cases of people who's hearts had stopped after being caught outside in sub-zero temperatures being successfully revived with no adverse effects.
This isn't cryonics by any stretch, but doctors are seriously looking to put gunshot victims into suspended animation by drastically cooling them down so they can be worked on [0]:
When a shooting or stabbing victim goes into cardiac arrest due to massive bleeding, even the most heroic attempts at resuscitation fail 90 percent of the time. But a study to begin this month under the direction of Sam Tisherman and Patrick Kochanek at the University of Pittsburgh Medical Center Presbyterian Hospital will see if there's a better way: cooling the body after the heart has stopped beating, to the point where all other functioning virtually ceases as well.
By putting patients literally into a state of suspended animation—or "emergency preservation," as Tisherman calls it—the surgeons intend to preserve brain functioning long enough to close wounds that would otherwise be fatal.
