This study documents the types and frequencies of injuries related to chest compressions during resuscitation attempts in a cohort of 436 non-traumatic, forensic autopsy cases from Eastern Denmark. We hypothesized that there would be a difference in types and frequencies of injuries seen after mechanical cardiopulmonary resuscitation (mCPR) compared to manual basic life support (BLS). We included all non-traumatic deaths referred for a forensic autopsy in eastern Denmark in the period 2015-2017, for a total of 436 cases (females, n = 146; males, n = 290), of which 75 cases had mCPR performed. Data on injuries were obtained from forensic autopsy reports. The mCPR group was characterized by a statistically significantly higher incidence of myocardial rupture (4 % vs. 0 %, p < 0.0001). We found no other statistically significant differences in the incidence of visceral trauma (e.g. haemothorax, pericardial haemorrhage, pulmonary contusions, liver or spleen injuries) between the two groups. In addition, characteristic injuries recorded in both groups included a high frequency of multiple rib fractures in the upper and middle parts of the rib cage, primarily located anteriorly, as well as sternum fractures, but these findings occurred almost twice as much in the mCPR group (77.3 % vs. 46.8 %, p < 0.0001).
本研究记录了丹麦东部436例非创伤性法医尸检病例在复苏尝试过程中与胸外按压相关的损伤类型和频率。我们假设，与手动基础生命支持（BLS）相比，机械心肺复苏（mCPR）后出现的损伤类型和频率会有所不同。我们纳入了2015年至2017年期间丹麦东部所有转介进行法医尸检的非创伤性死亡病例，共计436例（女性146例；男性290例），其中75例进行了mCPR。损伤数据来自法医尸检报告。mCPR组的心肌破裂发生率在统计学上显著更高（4%对0%，p<0.0001）。我们发现两组之间在内脏创伤（如血胸、心包出血、肺挫伤、肝或脾损伤）发生率方面没有其他统计学上的显著差异。此外，两组记录的特征性损伤包括肋骨中上段多处肋骨骨折的高频率，主要位于前部，以及胸骨骨折，但这些发现在mCPR组中出现的频率几乎是另一组的两倍（77.3%对46.8%，p<0.0001）。
