Mechanical CPR No Better Than Manual CPR in Out-of-Hospital Cardiac Arrest

Mechanical CPR does not improve survival over manual CPR in adults with out-of-hospital cardiac arrest, according to a study published in the Lancet and presented at the American Heart Association meeting in Chicago.

Over 400 U.K. emergency vehicles were randomized to deliver CPR either manually or with the LUCAS-2 chest compression device. Nearly 4500 patients were enrolled over 3 years. The primary outcome, 30-day survival, did not differ significantly between the groups. There were no serious adverse events.

The authors note that previous randomized trials also found no survival benefit with mechanical CPR. Commentators add that mechanical CPR is more expensive, but point out: "Safety concerns for unrestrained crew using manual CPR in a moving ambulance are real. Mechanical CPR allows crews to be safely belted up and is a logical choice from the safety perspective."
