NEW YORK (Reuters Health) – Use of mechanical cardiopulmonary resuscitation devices (mCPR) for out-of-hospital cardiac arrest was associated with less favorable neurologic outcomes than manual CPR in a recent analysis.
“The use of mCPR to deliver CPR has become more widespread, although a survival advantage has not been demonstrated in randomized, controlled trials. Little is known about real-world use of mCPR or the association with outcomes,” write Dr. Joseph Rossano of Children’s Hospital of Philadelphia, Pennsylvania and colleagues in Circulation, online December 19.
To investigate, the team analyzed registry data from 2013 to 2015 on 80,861 individuals (median age, 62) who experienced nontraumatic out-of-hospital cardiac arrest, 35.1% of whom received bystander CPR. Researchers compared outcomes for those treated with mCPR (17,625) and those receiving manual CPR only (63,056).
Although time of cardiac arrest, time of first CPR, and timing of the interventions were not reliably reported for all participants, information was available for return of spontaneous circulation – whether it occurred before or after advanced life support measures were initiated.
