Purpose: The aim of this descriptive study was to explore the relationship between non-technical skills (NTSs) and cardiopulmonary resuscitation (CPR) performance of nurses' teams in simulated cardiac arrest in the hospital. Methods: The sample was 28 teams of nurses in one university hospital located in Seoul. A high fidelity simulator was used to enact simulated cardiac arrest. The nurse teams were scored by raters using both the CPR performance checklist and the NTSs checklist. Specifically the CPR performance checklist included critical actions; time elapsed to initiation of critical actions, and quality of cardiac compression. The NTSs checklist was comprised of leadership, communication, mutual performance monitoring, maintenance of guideline, and task management. Data were collected directly from manikin and video recordings. Results: There was a significant difference between the medians of the NTSs and CPR performance (Mann Whitney U=43.5, p=.014). In five subcategories, communication (p=.026), mutual performance monitoring (p=.005), and maintenance of guideline (p=.003) differed significantly with CPR performance in medians. Leadership (p=.053) and task management (p=.080) were not significantly different with CPR performance. Conclusion: The findings indicate that NTSs of teams in addition to technical skills of individual rescuers affect the outcome of CPR. NTSs development and assessment should be considered an integral part of resuscitation training.

During the emergency situation such as cardiac arrest, cardiopulmonary resuscitation(CPR) is the most important treatment to maintain patient's blood circulation. Since the quality of CPR can not be easily measured or evaluated by the eye, an assistive device with an accelerometer can help to assess the pressure depth of CPR. In this study, we propose a single frequency analysis method to reduce the error of the accelerometer by extracting only one frequency component from the Fourier transform process. To verify the effectiveness of the single frequency analysis, acceleration data at CPR conditions were measured at a sampling rate of 50 / sec using a wristband equipped with an acceleration sensor. Then, We compared the existing distance estimation method and the single frequency analysis method using the measured data. The amplitude value proportional to the compression depth was obtained by applying the single frequency analysis method.

In this paper, we propose a the effects of new chest compressions in the implementation of chest compressions during infant cardiopulmonary resuscitation, and to provide basic data for high-quality CPR. On March 12, 2019, the research target used the SPSS 22.0 Version as an experimental study using randomized cross-design of 30 emergency medical services students who completed BLS Health Care-provider. The study also showed significant differences in chest depth and average rate of pressure($34.61{\pm}1.29$, $39.40{\pm}1.08$, <0.001, $105.46{\pm}4.23$, $107{\pm}3.84$, <0.001) depending on chest compressions. There was also a significant difference in the convenience and degree of pain of chest compressions(<0.001). In addition, new chest compressions appeared close to vertical and showed statistically significant differences(p<.001). Based on the results of this study, we can see that the accuracy of the new chest compressions during infant cardiopulmonary resuscitation is increased, and the depth of chest compressions is improved, improving the quality index of chest compressions. However, it will be necessary to further study the use of the new chest compressions to identify the potential for clinical use.

Traumatic ventricular septal defect (VSD) resulting from blunt chest injury is a very rare event. The mechanisms of traumatic VSD have been of little concern to dateuntil now, but two dominant theories have been described. In one, the rupture occurs due to acute compression of the heart; in the other, it is due to myocardial infarction of the septum. The clinical symptoms and timing of presentation are variable, so appropriate diagnosis can be difficult or delayed. Closure of traumatic VSD has been based on a combination of heart failure symptoms, hemodynamics, and defect size. Here, we present a case of a 4-year-old boy who presented with a traumatic VSD following a car accident. He showed normal cardiac structure at the time of injury, but after 8 days, his repeated echocardiography revealed a VSD. He was successfully treated by surgical closure of the VSD, and has been doing well up to the present. This report suggests that the clinician should pay great close attention to the patients injured by blunt chest trauma, keeping in mind the possibility of cardiac injury.

Purpose: This study aimed to compare the effects of rescue ventilation maneuvers on the quality of two-rescuer cardiopulmonary resuscitation (CPR). Methods: We implemented mouth to mouth (MMV), mouth to pocket mask (MPV) and bag-valve mask ventilation (BMV) maneuvers. Each team of two-nurses was randomized to perform three consecutive sessions of two-rescuer CPR by using three artificial ventilation maneuvers. Results: The subjects were 26 teams of nurses (female: 96.2%, male: 3.8%, age: 26.6 years). Failed ventilation was more frequent in BMV ($2.23{\pm}2.21$, p <.001) than MMV ($0.31{\pm}0.74$) and MPV ($0.38{\pm}0.64$). BMV had more compressions per minute ($93.7{\pm}5.7$) than MMV ($87.0{\pm}7.2$, p = .001) and shorter total compression pause time ($46.1{\pm}5.8sec$) and compression pause fraction ($23.3{\pm}2.2%$) than MMV ($54.8{\pm}10.3sec$, p = .001, $25.5{\pm}3.5%$, p = .001, respectively) and MPV ($53.1{\pm}7.1sec$, p =. 006 and $25.8{\pm}2.6%$, p = .006, respectively). Conclusion: In our simulation study, BMV reduced the compression pause time and increased the number of compressions per minute, thus indicating CPR provided to patients was effective. However, considering the high rate of ventilation failure, we recommend periodic training.

본 연구는 74세 여자 환자가 심정지 후 일반인과 119구급대원들에게 시행된 심폐소생술의 합병증인 기복증에 대한 증례를 경험하였기에 이에 대한 임상양상과 병태생리를 조사하기 위해 시도되었다. 평소 건강했던 74세 여자가 식당에서 일하던 중 갑자기 발생한 의식저하로 쓰러졌다. 증상발생 후 즉시 119에 신고를 하였고 현장에서 목격자에 의한 즉각적인 심폐소생술이 시행되었으며, 현장에 도착한 119구급대원에 의한 심폐소생술과 제세동이 시행된 결과 자발순환을 회복하였다. 자발순환 회복 후 환자는 인근 2차병원으로 이송되어 시행한 심전도 검사에서 급성심근경색이 의심되어 추가적인 검사와 치료를 위해 3차병원으로 이송되었다. 이후 시행한 X-ray 검사와 복부전산화 단층촬영 검사결과 위문접합부의 파열과 다량의 기복증을 보여 수술치료를 결정하였으나 수술실에서 다시 심정지가 발생하여 심폐소생술을 시행하였으나 환자는 결국 사망하였다. 따라서 병원 전 현장에서 심폐소생술을 시행 할 때 흉부압박의 정확한 위치 선정이 필요하며 양압 환기에 대한 신중한 고려가 필요하겠다. 또한 심폐소생술 후 발생한 기복증의 치료는 환자의 혈역학적 상태를 충분히 고려해야 할 것으로 사료된다.

Because of location, a mediastinal mass may cause complications such as a major airway obstruction, a superior vena caval obstruction, and cardiac compression during general anesthesia. The patient's condition need to be assessed by several methods to predict the risks associated with general anesthesia. The authors took computed tomographs for a preoperative evaluation of two patients with an anterior mediastinal mass, and the risk of perioperative complications was predicted by measuring the tracheal area. The patients were managed according to the preoperative evaluation but severe ventilation impairments were encountered during anesthesia. In one patient, stable ventilation could not be maintained until spontaneous breathing appeared. The operation was cancelled and the patient was brought into the ICU. In the other patient, a tracheal tube was inserted deeper in an attempt to pass the narrowed tracheal portion due to mediastinal tumor compression resulting in improved ventilation.
