Doctors place patient in 'suspended animation'

Rapid cooling technique to 'buy time' trialled by surgeons on at least one patient near death

Surgeons have placed a patient in suspended animation for the first time, using a technique that cools the brain to below 10°C and replaces the blood supply with ice-cold saline. 


Dr Samuel Tisherman, of the University of Maryland School of Medicine, tells New Scientist that his team has put at least one patient in suspended animation.
