Hypothermia and cardiac arrest: the promise of intra-arrest cooling

Over the past several years, the implementation of therapeutic hypothermia has provided an exciting opportunity toward improving survival from out-of-hospital cardiac arrest. There are compelling data to support the prompt use of therapeutic hypothermia for initial survivors from out-of-hospital cardiac arrest, but animal data have suggested that initiation of therapeutic hypothermia during the intra-arrest period may significantly improve outcomes even further. In the first feasibility study in humans, Bruel and colleagues report on the implementation of this intra-arrest approach among patients suffering out-of-hospital cardiac arrest, an exciting prospect that is discussed in the present commentary.
