OBJECTIVE: To determine the effects of cardiopulmonary resuscitation (CPR) with AutoPulse™ (LDB-CPR) on post-resuscitation injuries identified by post-mortem computed tomography (PMCT). AutoPulse™ is a novel mechanical chest-compression device with a load-distributing band (LDB) that may affect post-resuscitation injury identified by PMCT.

METHODS: We conducted a retrospective cohort study of non-traumatic adult out-of-hospital cardiac arrest patients whose death was confirmed in our emergency department between October 2009 and September 2014. Patients were divided according to whether LDB-CPR (LDB-CPR group) or manual CPR only (manual CPR only group) was performed. The background characteristics and post-resuscitation injuries identified by PMCT were compared between both groups. Logistic regression was used to identify risk factors for posterior rib fracture and abdominal injury.

RESULTS: Overall, 323 patients were evaluated, with 241 (74.6%) in the LDB-CPR group. The total duration of CPR was significantly longer in the LDB-CPR group than in the manual CPR only group. Posterior rib fracture, hemoperitoneum, and retroperitoneal hemorrhage were significantly more frequent in the LDB-CPR group. The frequencies of anterior/lateral rib and sternum fracture were similar in both groups. Pneumothorax tended to be more frequent in the LDB-CPR group, although not significantly. LDB-CPR was an independent risk factor for posterior rib fracture (odds ratio 30.57, 95% confidence interval 4.15-225.49, P=0.001) and abdominal injury (odds ratio 4.93, 95% confidence interval 1.88-12.95, P=0.001).

CONCLUSIONS: LDB-CPR was associated with higher frequencies of posterior rib fracture and abdominal injury identified by PMCT. PMCT findings should be carefully examined after LDB-CPR.
