Benefit of adrenalin in CPR questioned

Use of adrenalin during CPR is linked with decreased survival in the longer term, despite being more likely to resuscitate patients, research finds.

A study of 400,000 out-of-hospital cardiac arrests showed patients who received IV adrenalin faced an almost 50% decreased chance of survival one month after the event compared with those not exposed to the drug.
