A large international study on the effects of cooling the brain after a cardiac arrest shows that contrary to current treatment recommendations, it doesn’t actually improve survival or recovery. The study, published today in the New England Journal of Medicine, suggests that a less intensive approach to temperature control in these patients may be warranted. Dr. Manoj Saxena, Post-Doctoral Research Fellow at The George Institute for Global Health and intensive care doctor at Bankstown-Lidcombe Hospital, helped lead the study for Australian hospitals that took part.
