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.

Ustilago maydis의 소생자는 물한천배지에서 접종후 8시간 후에 98% 이상 발아하였다. PDA를 포함한 기타 영야배지에서의 발아율도 이와 비슷하였다. 소생자 발아에 가장 적당한 온도는 3$0^{\circ}C$였으며 $25^{\circ}C$나 35$^{\circ}C$순으로 양호하였으나 2$0^{\circ}C$나 그 이하의 저온에서는 발아율이 급격히 떨어졌다. 소생자는 pH 5~9의 범위에서 80%이상 발아하였으나 최적 pH는 6~7이었다. 광조사는 소생자 발아에 큰 영향을 미치지 못하였다. 소생자는 자유수분(RH 100%)하에서 24시간 후 81%가 발아하였으나 상대습도가 93%나 그 이하에서는 발아율이 19~34%였다. 이 실험결과는 소생자 발아에 가장 큰 영향을 미치는 환경요인은 온도와 습도였으며 우리나라 기후조건에서 소생자는 7~8월의 한여름철 장마기간 동안 왕성하게 발아할 수 있음을 뜻하고 있다.

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.

옥수수 깜부기병균 Ustilago maydis 동포자를 풍건한 후 모래나 silica gel을 보존매체로 해서 4$^{\circ}C$나 그 이하 온도에서 24개월 두었을 때 동포자 생존율은 40~45%였다. 동포자는 28$^{\circ}C$ PDA상에서 쉽게 발아하여 많은 소생자를 형성하였다. U. maydis 동포자로부터 소생자 형성의 최적배지는 corn meal broth였고, carrot broth와 potato-dextrose broth의 순으로 좋았다. 소생자 형성에 가장 적합한 조건은 온도 28~3$0^{\circ}C$, pH5~7이었다. 소생자 형성은 암조건에서 보다 좋았다.

옥수수 유묘접종시 깜부기병이 가장 잘 발병하는 조건은 4엽기 옥수수묘를 10\ulcorner~10\ulcorner/ml 농도의 소생자 현탁액으로 경엽살포한 후 28~3$0^{\circ}C$의 습실상에서 24시간 둔 후 꺼내어 온실에 두었을 때였다. 유묘의 엽기가 이보다 어리거나 접종원 농도가 이보다 높을 때, 혹은 습실상내 처리기간이 길어지면 접종후 유묘의 이른 고사를 초래하였다. 또한 습실상의 온도가 낮아질수록 깜부기병의 발병정도도 감소하였다. 깜부기병의 발생은 소생자 현탁액의 경엽살포 및 줄기주사접종에 의해서는 가능하였지만 토양관주에 의해서는 발병하지 않았다. 소생자 현탁액은 별도의 영양원의 첨가 없이도 발병을 잘 유도하였다. 동포자 현탁액을 직접 경엽살포하거나 줄기주사접종하여도 발병하였으나 소생자 현탁액접종에 비하여 발병정도가 현저히 낮았다.

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.
