Suspended animation for six hours… in rats

Fred Hutchinson Cancer Research Center (Seattle) has been able to induce rats into suspended animation for up to six hours by using hydrogen sulphide to suspend the demand for oxygen. Larger animals have been able to be suspended for up to twenty minutes.
Note that this is not true suspended animation. This is more of a hibernation where breathing has been slowed to point where the Lazarus effect occurs.
