The researchers behind it don't want to call it suspended animation, but it's the most conventional way to explain it. The world's first humans trials will start at the UPMC Presbyterian Hospital in Pittsburgh, with 10 patients whose injuries would otherwise be fatal to operate on. A team of surgeons will remove the patient's blood, replacing it with a chilled saline solution that would cool the body, slowing down bodily functions and delaying death from blood loss. According to Dr. Samuel Tisherman, talking to New Scientist: "We are suspending life, but we don't like to call it suspended animation because it sounds like science fiction... we call it emergency preservation and resuscitation."
Successful tests on pigs were achieved in 2000. After inducing fatal cuts, scientists were able to drop the body temperatures by around 10 degrees celsius. All the control pigs died, while those 'preserved" had a 90 percent survival rate - after some heart restarts.
