title: [Traumatic changes of intrathoracic organs due to external mechanical cardiopulmonary resuscitation. Case reports].
abstract: External mechanical resuscitation systems were developed for continuous and effective chest compression with the goal to increase the probability of spontaneous blood circulation renew. We describe results of four autopsy cases, where the external mechanical resuscitation by system Lucas (n=3) and AutoPulse (n=1) was performed prior to death. In all the cases were found traumatic changes which are commonly described in various studies such as skin abrasions on the chest, multiple rib fractures, fracture of the sternum and hematoma in the mediastinum or pericardium. In addition to these usual traumatic changes accompanying mechanical cardiopulmonary resuscitation we have observed injuries of intrathoracic organs, mainly the contusions of the heart and contusions and laceration of the lungs. In addition to these changes were in one case, associated with prolonged AutoPulse resuscitation, found ruptures of intima of the right common carotid artery. These injuries, with few exceptions, are not commonly described even over much wider number of examined persons. Injuries of the abdominal organs in connection with mechanical resuscitation, as described in a few case reports, were not present. However in one case there was found contusion of myocardium due to the external resuscitation by the Lucas system with clinical manifestation of sudden coronary incident even though the cause of death was massive thrombotic embolism to pulmonary arteries. All reported cases were similar in the relatively long-lasting mechanic cardiopulmonary resuscitation and prolonged time of dying of the patients.
