Study questions adrenaline for cardiac arrest

There is an increased risk of severe neurological impairment

A new study is challenging the widespread practice of having paramedics give adrenaline at the scene of a cardiac arrest.


The study found that adrenaline helped an extra 1% survive by “restarting the heart”, but it almost doubled the risk of severe neurological impairment.

The authors say the results, which are published in the New England Journal of Medicine, will have a major impact on the way cardiac arrests are treated around the world.

“We now have a decision to make about the small survival benefit vs the large increased risk of debilitating brain damage when giving adrenaline," says Dr David Nunan of the University of Oxford, who was not involved in the research..

But Dr Sam Parnia of New York University Langone Medical Center says that, based on the results, "it is hard to agree with the assumption that adrenaline itself is leading to increased brain
