Abstract

[Indexed for MEDLINE] 7. Soud Lek. 2023 Fall;68(3):33-36. Pulmonary fat embolism after cardiopulmonary resuscitation. [Article in English] Rudinská LI, Delongová P, Vaculová J, Ihnát P. Pulmonary fat embolism (PFE) is usually observed in patients with long bone fractures, patients with extensive subcutaneous fat contusions or skin burns. Chest compressions during cardiopulmonary resuscitation (CPR) present powerful repetitive violence against victim's chest. Skeletal chest fractures are the most frequent complication of CPR, and probably the most important cause of PFE autopsy finding in persons, which have been resuscitated before death. The aim of the present paper was to investigate the prevalence and seriousness of PFE in non-survivors after out-of-hospital cardiac arrest. During autopsy, PFE can be diagnosed in 30 - 42 % of persons after unsuccessful CPR; skeletal chest fractures are associated with significantly higher prevalence of PFE. After successful CPR, fat embolism may contribute significantly to acute respiratory distress syndrome, or multiorgan failure. The issue of CPR associated injuries has two medical aspects - clinical and forensic. From clinical point of view, the presence of CPR associated injuries must be acknowledged when offering healthcare to patients after successful CPR. During autopsy, CPR associated injuries should be diagnosed and evaluated as these injuries may contribute to death or may be potentially lethal.
