Most people who have a cardiac arrest die. Many who are resuscitated subsequently die over the next few hours or days, and those who survive are at risk of cognitive dysfunction. This gloomy reality has prompted research into interventions to improve the prognosis of cardiac arrest; one of these interventions is the induction of mild hypothermia after spontaneous circulation has been restored.
Apart from patients resuscitated from a very brief cardiac arrest, most survivors will be comatose initially, and those without extensive comorbidity will be admitted to an intensive care unit. Unconscious, mechanically ventilated survivors of cardiac arrest account for one in 17 of all admissions to intensive care in the United Kingdom.1 A third of these patients survive to hospital discharge. In one centre, two thirds of deaths in intensive care in initial survivors of cardiac arrest that occurred out of hospital, and a quarter of deaths after cardiac arrest that occurred in hospital, were attributed primarily to a neurological cause.2
