Dr Kevin Fong investigates a pioneering technique of extreme cooling
that is being used to bring people back from the dead.
In the operating theatre, a patient's heart is stopped and their brain
shows no activity. They are indistinguishable from someone who is dead.
Yet patients can then be warmed up and brought back to life. Kevin Fong
meets the doctors who have developed this procedure, finds out how it
could revolutionise intensive care and trauma medicine, and meets some
of the remarkable people who have been brought back from the dead.
