    Abstract:
    The current standard technique for cardiopulmonary resuscitation (CPR), initially described in the early 1960s, has quickly become the expected response for all persons found without a pulse or respiration. Despite the potentially lifesaving properties of external cardiac massage, the mainstay of resuscitation, it consists of repeated blunt force trauma to the chest, which can lead to extensive traumatic skeletal and nonskeletal injuries. Numerous autopsy-based studies have documented the incidence and patterns of rib and sternal fractures associated with attempted CPR, but there is relatively little data on the incidence and severity of nonskeletal CPR-related injuries. We reviewed reports from 1878 autopsies performed between September 2017 and December 2019 (inclusive), for documentation of CPR-related injuries. Among these cases, there were 93 cases with resuscitation-related nonskeletal injuries. The most common type of injury identified were visceral contusions, documented in 57.0% of cases. These contusions predominantly involved the heart, lungs, neck soft tissue, and surrounding structures. Resuscitation-related lacerations were seen in 17.2% of the cases, most predominantly involving the pericardium, heart, and liver. Statistical analysis of the data demonstrated that lacerations were more likely to be seen in females and with associated sternal fractures. Additionally, hemothoraces were present in 34.4% of cases and hemopericardium was seen in 8.6% of cases. This study provides additional documentation of the range, severity, and incidence of various types of resuscitation-related visceral injuries to better assist autopsy pathologists in distinguishing these injuries from other antecedent traumatic injuries.
