Suspended animation success: "Researchers are testing potentially life-saving techniques for keeping humans in a state of suspended animation while surgeons repair their wounds. US doctors have developed a method of inducing hypothermia to shut down the body's functions for up to three hours. In tests, they reduced the body temperature of injured pigs from 37C to 10C before operating on them and then reviving them. Now they are applying for permission to test the procedure on casualty patients without a pulse who have lost large amounts of blood, New Scientist magazine reported. It is thought this method and others could one day be used on car crash and gunshot victims, as well as in the battlefield to treat wounded soldiers. A surgeon at Massachusetts General Hospital in Boston, Hasan Alam, has tested the technique about 200 times on pigs, with a 90 per cent success rate".
