Trauma associated with cardiopulmonary resuscitation based on autopsy reports after the 2015 ERC guidelines.

INTRODUCTION: Cardiopulmonary resuscitation (CPR)-related injuries have not been assessed since the 2015 Resuscitation Guidelines were established. AIM: To describe the incidence and severity of CPR-related injuries, and to evaluate the impact of the 2015 European Resuscitation Council (ERC) guidelines on the objective assessment of injuries. METHODS: This multicenter, retrospective study analyzed autopsy reports of patients who underwent CPR. The most severe injuries were objectively assessed using the Abbreviated Injury Scale (AIS) and all injuries were summarized according to the New Injury Severity Score (NISS). RESULTS: Among 628 autopsy reports analyzed, patient characteristics and case details were distributed as follows: male sex, 71.1%; median age, 67 years; out-of-hospital cardiac arrest, 89.2%; bystander CPR, 56.8%. CPR-related injuries included: rib(s) 94.6%; lung(s), 9.9%; sternum, 62.4%; liver, 2.5%; and spleen, 1.8%. The incidence of bystander-provided CPR and severity of injury were similar to CPR provided only by professionals. There were no difference between mechanical and manual compressions. Females were older (p = 0.0001) and, although the frequency of their injuries was similar to males, they were significantly more severe (p = 0.01). Patients with life-threatening injury exhibited a baseline profile similar to those without injury . The median score (according to AIS) of the most severe injury was 3 and the median of summary of injuries was 13 according to the NISS-low risk of fatal injury. CONCLUSION: CPR-related injuries occurred frequently, although those that were life-threatening accounted for only 3% of cases. There were no differences between patients who were resuscitated by bystander(s) or by professionals and no differences between mechanical chest devices or manual resuscitation. Compared with a study based on the 2010 guidelines, similar injuries were found, but with more rib fractures, less visceral organ damage, and fewer life-threatening injuries.

Endovascular Management of Acute Embolic Occlusion of the Superior Mesenteric Artery: A 12-Year Single-Centre Experience.

PURPOSE: Retrospective evaluation of 12-year experience with endovascular management of acute mesenteric ischemia (AMI) due to embolic occlusion of the superior mesenteric artery (SMA). MATERIALS AND METHODS: From 2003 to 2014, we analysed the in-hospital mortality of 37 patients with acute mesenteric embolism who underwent primary endovascular therapy with subsequent on-demand laparotomy. Transcatheter embolus aspiration was used in all 37 patients (19 women, 18 men, median age 76 years) with embolic occlusion of the SMA. Adjunctive local thrombolysis (n = 2) and stenting (n = 2) were also utilised. RESULTS: We achieved complete recanalization of the SMA stem in 91.9 %. One patient was successfully treated by surgical embolectomy due to a failed endovascular approach. Subsequent exploratory laparotomy was performed in 73.0 % (n = 27), and necrotic bowel resection in 40.5 %. The total in-hospital mortality was 27.0 %. CONCLUSION: Primary endovascular therapy for acute embolic SMA occlusion with on-demand laparotomy is a recommended algorithm used in our centre to treat SMA occlusion. This combined approach for the treatment of AMI is associated with in-hospital mortality rate of 27.0 %.
