응급의학은 여러 가지 질환이나 외상, 사고 등의 원인으로 생명이 위독한 상태에 있는 긴급한 사람을 신속히 진단하고 치료하는것이 주 역할이나, 때로는 사람이 사망하였을경우 이를 다시 살리는 이른바 심폐소생술을 시행함으로써 죽은 사람을 살리는 일도 취급한다. 이러한 행위를 심폐소생술이라 일컫는 이유는, 사람이 죽으면 심장이 멎고 폐를 통한 호흡이 중단되므로 호흡과 심장박동을 인위적으로 다시 소생시켜 주는 시술이기 때문이다. 심폐소생술에는 기본심폐소생술과 전문심폐소생술로 구분한다.

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.

Background: Portable cardiopulmonary bypass(CPB) technique has been used increasingly as a potent and effective option for emergency cardiopulmonary resuscitation(CPR) because it can maintain more stable hemodynamics and provide better survival than conventional CPR techniques. This study was designed to develop a prototype of Korean portable CPB system and, by applying it to CPR, to discriminate whether it would be superior to standard open-chest CPR. Material and Method: By using adult mongrel dogs, open-chest CPR(OCPR group, n=4) and portable-CPB CPR(CPB group, n=4) were compared with respects to restoration of spontaneous circulation(ROSC), hemodynamics, effects on blood cells, blood gas patterns, biochemical markers, and survivals. Ventricular fibrillation-cardiac arrest(VF-CA) of arrest(VF-CA) of 4 minutes followed by basic life support(BLS) of 15 minutes was applied in either group, which was standardized by the protocol of American Heart Association. Then, advanced life support(ALS) was applied to either group under the support of internal cardiac massage or CPB. ALS was maintained until ROSC was achieved but not longer than 30 minutes regardless of the presence of ROSC. All of the measured values were expressed as means±SD percent change from baseline. Result: During the early ALS, higher mean arterial pressure was maintained in CPB group than in OCPR group(90±19 vs. 71±32 %; p<.05) and lower mean pulmonary arterial pressure was also maintained in CPB group than in OCPR group(105±24 vs. 146±6%; p<.05). ROSC was achieved in all dogs. Post-ROSC levels of hematocrit, RBC, and platelet were decreased and plasma free hemoglobin was increased significantly in CPB group compared to OCPR group(p<.05). Changes in blood gas patterns, lactate, and CK-MB levels were not different between groups. Early mortality was seen in 3 dogs in OCPR group(survival time 31±36 hours) and 2 in CPB group(228±153 hours, p=ns). The remainders in both groups showed prolonged survival. Conclusion: These findings indicate that portable CPB can be effective to maintain stable hemodynamics during cardiac arrest, to achieve ROSC and to prolong survival. Further study is needed to refine the portable CPB system and to meet clinical challenges.

Purpose: The purpose of this study was to examine nurses' emotional responses and ethical attitudes towards elderly patients' Do-Not-Resuscitate (DNR) decision. Methods: Data were collected using a questionnaire which was filled out by 153 nurses who worked in nursing homes and general hospitals. Data were analyzed using real numbers, percentages, means, standard deviations and Pearson's correlation coefficients with SPSS 19.0 program. Results: The average score for ethical attitudes towards the DNR decision was 2.68 out of 4. Under the ethical attitudes category, the highest score was found with a statement that said 'Although they will not perform cardiopulmonary resuscitate (CPR), it is right to do their best with other treatments for DNR Patients'. Items regarding emotional responses to the DNR decision, the average score was 2.36 out of 4. Among them, the highest score was achieved on 'I understand and sympathize'. No significant correlation was found between ethical attitudes and emotional responses in relation to patients' DNR decision (r=-0.12, P=0.13). Conclusion: Regarding elderly patients' DNR decision, nurses showed somewhat highly ethical attitudes and slightly positive emotional response. A follow-up study is needed to investigate variables that affect our results.

Purpose: This study investigated changes in life-sustaining treatments in terminally ill cancer patients after consenting to a do-not-resuscitate (DNR) order. Methods: Electronic medical records were reviewed to select terminally ill cancer patients who were treated at the oncology unit of the Asan Medical Center, a tertiary hospital in South Korea and died between January 1, 2013 and December 31, 2013. Results: The median (range) age of the 200 patients was 59 (22~89) years, and 62% (124 persons) were male. Among all patients, 83.5% were aware of their medical condition, and 47.0% of the patients had their DNR order signed by their spouses. The median of the patients' hospital stay was 15 days, and time from admission to DNR decision was 10 days. After signing a DNR order, 35.7~100% of the life-sustaining treatments that had been provided at the time of the DNR decision making were administered. The most commonly discontinued interventions were transfusion (13.5%), blood test (11.5%) and parenteral nutrition (8.5%). Conclusion: It is necessary to define the scope of life-sustaining treatments for DNR patients. Treatment guidelines should be established as well to secure terminal patients' death with dignity after their consent to a DNR order, thereby avoiding meaningless life-sustaining treatments and allowing administration of active terminal care interventions.

Background: Effective cardiopulmonary resuscitation (CPR) should provide acceptable hemodynamics for the vital organs during cardiac arrest and early restoration of spontaneous circulation that guarantees long-term, neurologically intact survival. CPR using heart-lung bypass has been suggested as an option for that use. This study was designed to determine the effectiveness of standard CPR techniques, closed-vs. open-chest CPR, which could be used in the future study verifying the role of heart-lung bypass CPR. Material and Method: By using adult mongrel dogs, closed-chest CPR (CCCPR, n=4) and open-chest CPR (OCCPR, n=5) were compared with respects to hemodynamics, restoration of spontaneous circulation(ROSC), and survival. Ventricular fibrillation-cardiac arrest (VF-CA) was induced by electrical shock in all animals. After 4 minutes of cardiac arrest, basic life support (BLS) was applied for 15 minutes and followed by advanced life support (ALS). ALS was maintained until achi ving ROSC but not longer than 30 minutes regardless of the recovery. Resuscitation procedures in either group were standardized by adopting the protocol of American Heart Association. Result: Prearrest baseline hemodynamic data was not different between two groups. During resuscitation, substantially higher systolic pressure was maintained in OCCPR group than in CCCPR group (45$\pm$15 vs. 33$\pm$11 mmHg during BLS, 83$\pm$36 vs. 44$\pm$15 mmHg during ALS; p=NS). Mean pulmonary arterial pressure went up to the level of mean systemic arterial pressures in CCCPR group and to half of that in OCCPR group, and had kept higher in CCCPR group throughout CPR (32$\pm$10 vs. 22$\pm$4 mmHg during BLS and 32$\pm$15 vs. 24$\pm$10 mmHg during ALS; p=NS). ROSC was obtained in 4 of 5 dogs receiving open-chest CPR and 2 of 4 closed-chest CPR. Prolonged survival was noted in all dogs in OCCPR group (6 to 1440 hours) but not in CCPR group (p<.05). Conclusion: These findings indicate that open-chest CPR can be more effective t maintain hemodynamics during cardiac arrest and to obtain restoration of spontaneous circulation and survival. Further experiment will be designed to compare heart-lung bypass CPR with open-chest CPR.

Purpose: The purpose of this study was to identify how nursing students' awareness of biomedical ethics and ethical values affect their attitudes towards a do-not-resuscitate (DNR) order. Methods: This cross-sectional correlation study was conducted with 275 nursing students enrolled at two universities in North Chungcheong Province and North Gyeongsang Province of South Korea. Data were collected in April 2017 using a self-reported questionnaire. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression with the SPSS/WIN 23.0 program. Results: The students' attitudes towards DNR were positively correlated with attitudes that seek ethical values but negatively correlated with their biomedical ethics awareness. The explained variance for attitudes towards DNR was 20%, which was significant (F=13.01, P<0.001). Conclusion: These findings suggest that nursing students' biomedical ethics awareness and ethical values were associated with their attitudes towards DNR. Curriculum organization and various educational programs should be developed and applied to help nursing students develop ethical values and awareness of biomedical ethics.
