IntroductionCardiopulmonary resuscitation (CPR)-related injuries are complications of chest compressions during CPR. This study aimed to investigate the differences and complications between mechanical and manual CPR techniques by using computed tomography (CT). MethodsPatients in whom return of spontaneous circulation was achieved after CPR and thorax CT imaging were performed for diagnostic purposes were included in the study. ResultsA total of 178 non-traumatic cardiac arrest patients were successfully resuscitated and had CT scans in the emergency department. The complications of CPR are sternum fracture, rib fracture, pleural effusion/hemothorax, and pneumothorax. There were no statistically significant differences in terms of age, first complaint, cardiac arrest rhythm, CPR duration, and complications between mechanical and manual CPR. The number of exitus in the emergency department was similar (p=0.638). The discharge from hospital rate was higher in the mechanical CPR group but there was no statistically significant difference (p=0.196). The duration of CPR was associated with the number of rib fractures and lung contusion, but it did not affect other CPR-related chest injuries. ConclusionThere was no significant difference observed in terms of increased complications in patients who received mechanical compression as compared with those who received manual compression. According to our results, mechanical compression does not cause serious complications, and the discharge from hospital rate was higher than for manual CPR; therefore, its use should be encouraged.

Aim: Cardiac arrests can be brought to emergency departments with an intervention from out-of hospital, and they can also occur for different reasons in the emergency department. Due to the high rates of mortality in this important clinical situation, regulations are made through guidelines and algorithms. Most of these regulations cover acute coronary syndromes and special conditions. The aim of our study is to evaluate intracranial hemorrhages in non-traumatic cardiac arrest cases in our emergency department for a period of 10 years. Material and Method: The data of patients 18 years of age and over who were found to have cardiac arrest in the emergency department between January 2011 and January 2021, who did not have trauma, were retrospectively scanned from the hospital information management system. Demographic information of all patients, computed tomography examinations for intracranial hemorrhage and emergency department outcomes were evaluated. Results: Of the 173 patients included in the study, 81 (46.8%) were women. The median age of the patients was determined as 72.00 (IQR 64.00-80-00). In the whole patient group, 20 (11.6%) patients had intracranial bleeding and 10 of these patients were women. More intrcranial hemorrhage was detected in the group that underwent CT before cardiopulmonary resuscitation (CPR) and it was statistically significant (p<0.001). In 4% of the patients who underwent CT after CPR, intracranial bleeding was detected. No difference was found in terms of the presence of bleeding or the timing of tomography in terms of discharge from the hospital. Conclusion: With this study, we found the rate of intracranial hemorrhage (ICH) to be 11.6% in patients with in-hospital cardiac arrest. As changes occur in the treatment and management of patients in the presence of ICH, we think that brain CT should be performed in the early period in cardiac arrest cases of unknown cause, as stated in the guidelines. Especially in the presence of change in consciousness and high blood pressure, it is important to organize algorithms in order to detect ICH.
