The purpose of this study is to evaluate the quality of chest compression by conducting comparison research between mechanical chest compressor(LUCAS) and manuale cardiopulmonary resuscitation(CPR) in a out-of-hospital environment and suggest effective advanced cardiac life support using mechanical chest compressors. For this, a out-of-hospital cardiac arrest was simulated with a team of 3 ambulance workers, and manuale CPR and CPR using LUCAS were performed on site and during transport in an ambulance. The research results are as follows: the comparison of manuale CPR between on site and in an ambulance revealed that on-site manuale CPR showed significant differences in the average compression depth, compression rate, and relaxation rate. Second, the comparison between manuale CPR and LUCAS in an ambulance showed significant differences in the average compression depth, compression rate, the number of compression per minute.

Purpose: This study was to investigate the resuscitation outcomes and the clinical characteristics of non-traumatic drug-induced out-of-hospital cardiac arrest by analyzing data from a single institution's registry. Method: We conducted a retrospective study of 795 patients who came to the emergency department with non-traumatic drug-induced out-of-hospital cardiac arrest during the period $1991{\~}2004$. Only patients over 18 years of age were included. Clinical characteristics. variables associated with cardiac arrest, and data during resuscitation were obtained from our cardiac arrest database. Patients were divided into two groups: drug-induced cardiac arrest (drug group, n=33), and non drug-induced cardiac arrest (non-drug group, n=762). Results: Spontaneous circulation was restored in 23 ($72{\%}$) patients in the drug group and in 314 ($45{\%}$) patients in the non-drug group ($x^2=0.020$). The patients who discharged alive number were 46 ($6{\%}$) in the non-drug group and 0 ($0{\%}$) in the drug group ($x^2=0.005$). The witnessed arrest, the epinephrine doses, and total defibrillation energy were not different between two groups. Conclusion: The return of spontaneous circulation rate was higher in the drug group than the non-drug group. However the drug group was lower survival discharge rate than in the non-drug group.

This study was conducted on 3,418 cases of cardiopulmonary arrest patients' detailed status table (2020, raw data) collected in 2020. Also, it is a retrospective narrative research that investigates and examines related laws and guidelines. The main findings are as follows. First, the implementation rate of 'bystander CPR' was 30.66% (1047 cases) and it was a remarkable result. It can be inferred the quality of the relevant laws and guidelines. Second, 'Public access defibrillation (shock)' accounted for only 0.10%(5 cases). it is considered that the relevant laws and guidelines are weighted towards 'stock and obligation.' Strategic differentiation of response by region is needed. Third, out-of-hospital cardiac arrest occurred at house was 71.97%(2,640 cases). To operate the 'special ambulance team' efficiently, it is necessary to analyze regional data more closely and develop an efficient strategy in the future.

Objective: The increasing number of people living in high-rise apartments may result in a delayed response from emergency medical technicians called out for an out-of-hospital cardiac arrest, making the role of apartment managers as the first responders extremely important. This study investigated whether automated external defibrillator (AED) placement influences the willingness of apartment managers to perform cardiopulmonary resuscitation (CPR) and use an AED. Methods: A cross-sectional target population-based survey was conducted in Daegu, July 2016. Questionnaires were sent to apartment managers working in apartments with more than 500 households. The general characteristics of the respondents, status of CPR education, and knowledge about and willingness to perform CPR and use an AED were investigated. Results: Of the 1,445 respondents, 758 (52.5%) worked in apartments with AEDs, of which 77.8% and 70.8% were willing to perform CPR and use an AED, respectively, compared with 68.1% and 60.0% of respondents who worked in apartments without AEDs. After adjusting for potential confounders, AED placement was associated with the willingness to perform CPR (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.04-1.71) and use an AED (OR, 1.39; 95% CI, 1.10-1.75). Prior CPR training and accurate knowledge of CPR skills were also associated with the willingness to perform CPR and use an AED. Conclusion: Placing AEDs in high-rise apartment buildings and providing refresher CPR education for maintaining CPR skills will be necessary to support apartment managers in their role as first responders.

A 55-year-old man was admitted to the trauma center after a car accident. Cardiac tamponade, traumatic aortic injury, and hemoperitoneum were diagnosed by ultrasonography. The trauma surgeon, cardiac surgeon, and interventional radiologist discussed the prioritization of interventions. Multi-detector computed tomography was carried out first to determine the severity and extent of the injuries, followed by exploratory sternotomy to repair a left auricle rupture. A damage control laparotomy was then performed to control mesenteric bleeding. Lastly, a descending thoracic aorta injury was treated by endovascular stenting. These procedures were performed in the hybrid-angio room. The patient was discharged on postoperative day 135, without complications.

The prognosis of patients who are comatose after resuscitation remains uncertain. The accurate prediction of neurological outcome is important for management decisions and counseling. A neurological examination is an important factor for prognostication, but widely used sedatives alter the neurological examination and delay the response recovery. Additional studies including electroencephalography, somatosensory-evoked potentials, brain imaging, and blood biomarkers are useful for evaluating the extent of brain injury. This review aimed to assess the usefulness of and provide practical prognostic strategy for pediatric postresuscitation patients. The principles of prognostication are that the assessment should be delayed until at least 72 hours after cardiac arrest and the assessment should be multimodal. Furthermore, multiple factors including unmeasured confounders in individual patients should be considered when applying the prognostication strategy.

The purpose of this study was attemped to investigate the clinical presentation and pathophysiology of 74-year-old female who developed pneumoperitoneum as complications of chest compression from sudden cardiac arrest. Such chest compression is the same one excercised to by-stander and paramedics. A healthy 74 year female had a sudden mental deterioration while working at a restaurant. She was transfered from 119 emergency medical system to the hospital. After the symptom developed, by-stander called 119 who carry out 6 minutes Cardiopulmonary resuscitation(CPR). Defibrillation and CPR was carried out by health provider after the arrival, and the patients spontaneous circulation returned. After Return of spontaneous circulation(ROSC), patients was transferred to the nearst hopspital, but suspicious of myocardial infarction, she was again transferred to a larger scale hospital. At the hospital she took X-rays and Abdominal CT, and the results of suspicious gastro-intestinal perforation near gastro-esophageal junction, surgical repair was recommended. But in operation room, while operation went on, cardiopulmonary arrest appeared again, and she expired. For this reason, prehospital CPR needs more accurate localization of cardiac massage and serious consideration of positive pressure ventilation. Moreover, treatment of pneumoperitoneum after CPR needs more cautious consideration of patients hemodynamic stability.

Purpose: We investigated the association between defoliant exposure and survival to discharge after out-of-hospital cardiac arrest. Methods: This is a retrospective case-control study based on the cardiopulmonary resuscitation (CPR) registry. The electronic medical records of out-of-hospital cardiac arrest victims from 6/9/2008 to 12/31/2016 were analyzed statistically. The case patients group had a history of defoliant exposure while the control group did not. Among the 401 victims studied, a total of 110 patients were male out-of-hospital cardiac arrest patients. Baseline characteristics and the parameters involved in cardiac arrest were analyzed and compared between the two groups after propensity score matching. The primary outcome was survival to discharge, and secondary outcomes were sustained return of spontaneous circulation (ROSC) and survival to admission. Results: After propensity score matching a total of 50 patients (case=25, control=25) were analyzed. Primary outcome (survival to discharge) was not significantly different between case and control groups [(OR, 1.759; 95% C.I., 0.491-6.309) and (OR, 1.842; 95% C.I., 0.515-6.593), respectively]. In the subgroup analysis, there were also no significant differences between the control group and subgroups in primary and secondary outcomes according to defoliant exposure severity. Conclusion: There is no statistically significant association between defoliant exposure and survival of out-of-hospital cardiac arrest.

Purpose: There has been an increase in the number of prehospital cardiac arrests due to increases in both cardiovascular diseases and the average age of the population, We performed this study to identify the proper resuscitation technique and AED to be used to increase the survival rate in prehospital cardiac arrest. Methods: We studied 57 victims with prehospilal cardiac arrest by EMT's Reports form January to December, 2004. Results: Fifty-seven of 92 victims were trasported with ECG in prehospital cardiac arrest. Ventricular fibrillation(VF)/ ventricular tachycardia was 56.2%, asystole was 33,3%, and pulseless electrical activity(PEA.) was 10.5% in initial rhythm analysis, There weren't attempt CPR in 14.0%. Twenty of the 32(62.5%) were shocked by AED for the adequacy method. There were no statistical differences the transportation time. Conclusion: With the increase in cardiovascular disease and old age, the number out-of-hospital cardiac arrests has risen accordingly. However, there were lack of CPR by bystander, defibrillation, advanced cardiac life support(ACLS) in prehospital stage. To improve the adequancy of basic life support and to increase the performance of ACLS, especially AED, we must create challenges to develop new protocols in prehospital care.

This study proposes an algorithm for removal of CPR artifact in order that automated external defibrillator (AED) can effectively diagnose ECG rhythm during cardiopulmonary resuscitation (CPR). Current AED required to interrupt chest compression for reliable rhythm analysis to avoid the effect of artifacts produced by CPR. However even temporarily interruption of chest compression during CPR adversely affects the probability of restoration of spontaneous circulation (ROSC) and survival after the delivery of the shock. Therefore, we proposed a method for removal of CPR artifacts using least mean square (LMS) filter. The removal of the CPR artifacts would enable compressions to continue during AED rhythm analysis, thereby increasing the likelihood of resuscitation success. It was tested on 31 segments of shockable and 300 segments of non-shockable ECG signals recorded from three pigs during CPR. In the result, sensitivity (Se) and specificity (Sp) analysis on the test segments showed values of Se = 3.2%, Sp = 66.0% and Se = 96.8%, Sp = 98.7% in the case of unfiltered and filtered signals during CPR. In conclusion, it was shown that the proposed method can be a useful tool to exactly diagnose the ECG rhythm during the CPR.
