Milling L, et al. - Researchers retrospectively examined patients who received either mechanical and/or manual cardiac compression in order to determine the extent and pattern of chest compression-related injuries. For this purpose, they manually reviewed all prehospital discharge reports, in-hospital records, and autopsy reports in patients who received physician-administrated therapy for out-of-hospital cardiac arrest in the region of Southern Denmark from 2015 to 2017. Overall, 84 patients undergoing manual and mechanical chest compression and 353 patients with manual chest compression only were examined. Findings revealed a robust link between mechanical chest compression as an adjunct to manual chest compression and potentially life-threatening visceral injuries. There was also an evident association of duration of chest compression with injury. The investigators recommended using mechanical chest compression only in situations where manual chest compression is not possible.
