Purpose: In-hospital cardiac arrest is rare, but often results in high mortality rates. Early and effective cardiopulmonary resuscitation (CPR) is crucial for survival and nurses are often the first responders. This study aimed to investigate how inter-professional attitudes and educational burdens affect self-efficacy related to CPR performance following team-based CPR simulation training. Methods: This retrospective observational study analyzed data from a satisfaction survey conducted after team-based CPR training sessions between January and November 2022. Of the 454 nurses surveyed, 238 were included in the study after excluding those with ambiguous responses. Multiple regression analysis was performed to assess factors influencing CPR self-efficacy. The factors examined included inter-professional attitudes and educational burden. Results: Higher levels of inter-professional attitudes, particularly regarding teamwork roles and responsibilities, lower educational burden, and a positive perception of CPR competence were all associated with improved CPR-related self-efficacy. Participants who reported higher engagement in teamwork, lower task load, and greater confidence in their CPR abilities demonstrated higher self-efficacy in performing CPR. Conclusion: Enhancing the competencies of nurses who may act as initial responders in CPR situations within or outside hospital settings can help save lives and support public health.

Background: Venoarterial extracorporeal membrane oxygenation (ECMO) is a key treatment method used with patients in cardiac arrest who do not respond to medical treatment. A critical step in initiating therapy is the insertion of ECMO cannulas. Peripheral ECMO cannulation methods have been preferred for extracorporeal cardiopulmonary resuscitation (ECPR). Methods: Patients who underwent ECPR at Daegu Catholic University Medical Center between January 2017 and May 2023 were included in this study. We analyzed the impact of 2 different peripheral cannulation strategies (surgical cutdown vs. percutaneous cannulation) on various factors, including survival rate. Results: Among the 99 patients included in this study, 66 underwent surgical cutdown, and 33 underwent percutaneous insertion. The survival to discharge rates were 36.4% for the surgical cutdown group and 30.3% for the percutaneous group (p=0.708). The ECMO insertion times were 21.3 minutes for the surgical cutdown group and 10.3 minutes for the percutaneous group (p<0.001). The factors associated with overall mortality included a shorter low-flow time (hazard ratio [HR], 1.045; 95% confidence interval [CI], 1.019-1.071; p=0.001) and whether return of spontaneous circulation was achieved (HR, 0.317; 95% CI, 0.127-0.787; p=0.013). Low-flow time was defined as the time from the start of cardiopulmonary resuscitation to the completion of ECMO cannula insertion. Conclusion: No statistically significant difference in in-hospital mortality was observed between the surgical and percutaneous groups. However, regardless of the chosen cannulation strategy, reducing ECMO cannulation time was beneficial, as a shorter low-flow time was associated with significant benefits in terms of survival.

배경: 심장 수술시 체외순환은 불가피하며 이때 발생하는 혈액 희석, 수혈, 염증반응, 부종 같은 부작용을 최소화하기 위해서 초기 충진액을 최소화하려는 많은 노력이 이루어졌다. 저자들은 최근 체외 순환 장비 및 운영방식의 개선으로 몸무게 10 kg 미만의 신생아 및 유아를 대상으로 체외순환 충진액의 양을 140 mL까지 줄일 수 있었으며 기존의 방법과 비교해보고자 하였다. 대상 및 방법: 2007년 7월부터 2008년 6월까지 본원에서 선천성 심장 기형으로 수술받게 될 5 kg 미만의 환아(n=97)를 대상으로 충진액 최소화 기법과 기존의 방법을 병행하여 수술을 시행하였다. 충진액 최소화 기법은, 심폐기 도관을 짧게 하고, 저혈조의 위치를 조절하며, 진공 배액을 사용하는 등 각 요소마다 충진액의 양을 줄일 수 있는 방법 등을 적용하는 것이었다. 연구 기간이 끝나고 난 뒤 후향적으로 체외순환기록지와 의무기록을 확인하였다. 결과: 새로운 충진액 최소화 기법을 사용한 환아는 46명이었으며 기존의 방법을 이용한 환아는 51명이었다. 양 집단에서 환아의 나이, 몸무게, 심페기 가동시간, 최저체온 등에 유의한 차이가 없었다(p>0.05). 그러나 충진액 최소화 기법을 사용한 환아와 기존의 방법을 사용한 환아에서 심폐기 초기 충진액의 총량은 각각 160.3$\pm$14.1 mL, 277.8+58.1 mL로 유의한 차이를 보였으며(p<0.001), 초기 농축적혈구 혼합량은 33.6$\pm$27.2 mL, 115.3$\pm$49.4 mL로 역시 유의한 차이를 보였다(p<0.001).수술 전 혈액검사에서 적혈구용적률은 오히려 충진액 최소화 기법 적용 군에서 평균 29.9%, 기존의 방법 군에서 평균 35.4%로 기존의 방법 군에서 유의하게 높았다(p<0.001). 각 군에 있어서 시행한 수술을 RACHS 카테고리에 의거해 난이도별로 나누었을 때 충진액 최소화기법 사용 군에서 시행한 수술이 기존의 방법 사용 군에서 시행한 수술에 비해 높은 난이도에 더 많이 분포하였다. 두 군 간에 수술 후 사망률이나 신경학적 합병증의 발생률에는 차이가 없었다. 결론: 체외순환 장비 및 운영방식의 개선으로 기존의 방법과 비교하여 획기적으로 초기 충진액 및 수혈을 줄일 수 있었고 체외순환으로 발생할 수 있는 여러 부작용을 최소화 하는데 도움이 될 것으로 생각되며 향후 이 같은 기법의 확대 보급이 필요할 것으로 생각된다.

Purpose: The purpose of this study was to investigate the effect of stretching, muscle strengthening, and walking exercise on the cardiopulmonary function and health-related quality of life in hemodialysis patients. Methods: Twenty-one patients in the intervention and the control group participated in the exercise respectively on maintenance hemodialysis at four university hospitals. The exercise was composed of 20 to 60 min per session, 3 sessions a week for 12 weeks. The effect of exercise was assessed by cardiopulmonary function (peak oxygen uptake, peak ventilation, peak respiration rate, maximal heart rate, and exercise duration) using a cycle ergometer. Grip strength was measured by dynamometer, and flexibility was measured by sit and reach measuring instrument. Health-related quality of life was measured using Medical Outcomes Study Short Form-36. Results: Peak oxygen uptake, peak ventilation, peak respiration rate, exercise duration, grip strength, flexibility, and physical component scale were significantly improved in the intervention group after 12 week's exercise compared to the control group. Conclusion: These findings indicate the exercise can improve cardiopulmonary function, grip strength, flexibility, and physical component scale of health-related quality of life in hemodialysis patients.

Objectives : This study is a quasi-experiment with a pre-post design and a nonequivalent control group performed from May 1 to June 2, 2013 to verify the effects of a simulation based education program on nursing students' self-confidence, and clinical performance ability. Methods : The subjects of the study were a total of 60 students in their fourth year of a nursing program at a university located in G city and they were assigned to an experimental group of 30 students and a control group of 30 students by convenience sampling. Results : After being offered education, self-confidence, and clinical performance ability were significantly more improved than before in each group. In the comparison of the two groups, the self-confidence (t=3.00, p=.004) and clinical performance ability(t=3.14, p=.003) of the experiment group were significantly higher than those of the control group. Conclusions : The results indicated that instructional methods using a simulation-based emergency care program should be adopted maximize the effects of advanced cardiopulmonary life support education.

Purpose : The purpose of this study was to investigate the variation of elapsed time in the cardiopulmonary resuscitation (CPR) quality and the fatigue in continuous CPR by single rescuer. This study will provide basic data about the time for the alternation of the CPR providers. Methods : The volunteer students having healthcare provider certification were recruited from the department of emergency medical service. The students performed 30:2 CPR for 20 minutes, and the data were recorded and analyzed. Metrics were based on the 2010 American Heart Association (AHA) Guidelines, and the CPR continued without any feedback. Results : Among the indicators of CPR, the accuracy and the depth of chest compressions decreased after about 5.3 minutes, and the rate increased approximately after 6.8 minutes. Changes in clinical indicators appeared, and fatigue increased after about 3 minutes. According to the increase in fatigue level, the changes in the CPR indicators and clinical indicators showed up, and these results proved to be statistically significant. However, there were no associations among the time, fatigue, and gender. Conclusion : Even though the times of changes in the indicators appeared differently, the times of changes in fatigue and CPR quality were able to be confirmed.

Purpose: This study was performed to determine the perception and attitude of emergency medical staff by the presence of family members while performing Cardiopulmonary Resuscitation (CPR). Methods: Data were collected from June and August in 2010 using questionnaire. The participants were 187 doctors and nurses who were working at emergency medical centers located at eight hospitals. Results: Approximately half of the medical emergency staff had previous experience of having requests from a patient's family members to remain present at the time of performing CPR. Most of the subjects did not know that the 2005 American Heart Association (AHA) guideline recommended including willing family members' during CPR. Doctors were more likely than nurses to recognize that the positive effects of family members being present during CPR. Conclusion: This study indicates that health professionals are not aware of the AHA guidelines for including family members during CPR of a patient and further that more doctors than nurses recognized the value of including willing family members during CPR.

Background: The aim of this study was to evaluate risk factors associated with difficult heparin reversal by protamine after cardiopulmonary bypass. Methods: Data from 120 consecutive patients who underwent open heart surgery from 2009 to 2017 were retrospectively reviewed. Patients were divided into 2 groups: (1) those in whom complete heparin reversal was achieved after a single infusion of protamine (group A, n=89); and (2) those who required more protamine for heparin reversal (group B, n=31). Results: Female sex, prolonged bypass time (>200 min), long aortic cross-clamping time (>120 min), and a lowest rectal temperature <26℃ were significant predictors of difficult heparin reversal. Larger amounts of fresh frozen plasma and platelet concentrate were transfused in group B than in group A. Conclusion: Surgeons' efforts to reduce operative time and avoid deep hypothermia may be helpful for increasing the likelihood of easy heparin reversal, especially in female patients.
