  • Purpose: This study measured return of spontaneous circulation (ROSC) in relation to dispatch distance in patients with out-of-hospital cardiac arrest. Methods: Of 2,347 out-of-hospital cardiac arrest patients transported by emergency medical technicians in J Province between January 1 and December 31, 2015, those under age 18, those with reserved resuscitation, and those with traumatic cardiac arrest, leaving 855 patients in the study sample. ROSC was compared between those with dispatch distance ${\leq}4km$ (short dispatch distance, 465 patients) and those with dispatch distance >4 km (long dispatch distance, 390 patients). Results: The mean was 2.17 km in the short dispatch group and 9.87 km in the long dispatch group (p=.000). Mean distance from was 6.49 km and 13.39 km in the two groups, respectively (p=.000). ROSC differed significantly between the short and long dispatch distance groups (7.1% for short dispatch distance, 3.6% for long dispatch distance, p=.025). The length of time from to cardiopulmonary resuscitation also differed significantly between the short and long dispatch distance groups (8.77 minutes and 14.63 minutes, respectively, p=.000). Conclusion: ROSC was lower in areas of long dispatch distance compared to those of short dispatch distance. We expect this was most likely due to differences in response time by age and dispatch distance to the scene of cardiac arrest. However, no significant differences were found between the groups in the factors affecting ROSC.

  • 병원외 심정지는 오늘날 우리나라의 중대한 보건문제로서, 환자의 퇴원 시 생존율은 3.5%이며, 이 중 1%만이 신경학적 기능을 회복하는 것으로 나타났다. 이처럼 낮은 병원외 심정지 환자의 생존율을 높이기 위해서는 병원 도착 전 환자의 자발적 순환을 회복시키는 것이 매우 중요하다. 따라서 본 연구에서는 질병관리본부의 2009년도 심정지 의무기록 조사 자료를 활용하여 병원외 심정지 환자의 자발적 순환 회복률을 향상시킬 수 있는 요인들에 대한 심층 분석을 수행하였다. 심정지 환자의 자발적 순환 회복에 영향을 미치는 요인은 의사결정나무기법을 적용하여 분석하였으며, 그 결과 도착전 CPR여부, 병원 도착전 심정지 목격여부, 심정지시 활동, 과거력(암/심장질환/뇌졸중), 심정지 발생 장소, 병원전 일반인 CPR여부, 신고~현장 도착까지 걸린 시간, 연령 등이 중요한 요인으로 밝혀졌다. 이 요인들의 조합을 통해 의사결정나무모형으로 분류된 심정지 환자는 총 16개 유형이었으며, 그 중 유형 1의 특징을 갖는 집단의 자발적 순환 회복률(29.6%)이 가장 높게 나타났다. 더불어 비공공장소에서 심정지가 발생한 환자에게 일반인이 CPR을 시행하였을 경우, 심정지 환자의 자발적 순환 회복률이 향상된 것으로 보아 지역주민들에 대한 CPR교육이 중요함을 파악할 수 있었다.

  • Unsatisfied results of return of spontaneous circulation (ROSC) estimates were caused by the fact that the predictability of the predictors was insufficient. This unmet estimate of the predictors may be affected by transitional events due to behaviors which occur during cardiopulmonary resuscitation (CPR). We thus hypothesized that the discrepancy of ROSC estimates found in statistical characteristics due to transitional CPR events, may affect the performance of the predictors, and that the performance of the classifier dichotomizing between ROSC and No-ROSC might be different during CPR. In a canine model (n=18) of prolonged ventricular fibrillation (VF), standard CPR was provided with administration of two doses of epinephrine 0 min or 3 min later of the onset of CPR. For the analysis of the likelihood of a successful defibrillation during CPR, Support Vector Classification was adopted to evaluate statistical peculiarity combining time and frequency based predictors: median frequency, frequency band-limited power spectrum, mean segment amplitude, and zero crossing rates. The worst predictable period showed below about 1 min after the onset of CPR, and the best predictable period could be observed from about 1.5 min later of the administering epinephrine through 2.0-2.2 min. As hypothesized, the discrepancy of statistical characteristics of the predictors was reflected in the differences of the classification performance during CPR. These results represent a major improvement in defibrillation prediction can be achieved by a specific timing of the analysis, as a change in CPR transition.

  • Purpose: We aimed to improve the survival rates of out-of-hospital cardiac arrest patients. Methods: We analyzed data regarding cardiopulmonary resuscitation (CPR) outcomes and clinical characteristics of out-of-hospital cardiac arrest patients. The data included prehospital emergency medical service reports of 207 patients, 135 patients of Heart Saver, who survived over 72 hours after return of spontaneous circulation (ROSC) in Gyeonggi-do from January, 2012 to December, 2013. Data were analyzed using SPSS 18.0 descriptive statistics. Results: Among patients who achieved ROSC, 87.6% were men and 73.6% were aged 41-70 years; 86.7% were cases of witnessed cardiac arrest, and cardiopulmonary resuscitation was performed by bystanders in 65.9% of cases. The initial electrocardiogram showed ventricular fibrillation or pulseless ventricular tachycardia in 96.3% of patients. The call time was 1.0 minutes, arrival time was 6.3 minutes, time spent at the scene was 8.0 minutes, hospital arrival time was 10.0 minutes, and total CPR duration was 9.6 minutes. The certificate of them was paramedics in 89.6%. Conclusion: To improve the survival rates of out-of-hospital cardiac arrest patients, standard prehospital care for these patients and educational programs regarding CPR for lay rescues should be developed.

  • 임신부에서 심정지가 발생하였을 때, 가장 중요한 것은 임신부를 소생시키는 것이다. 임신부에서의 심정지는 산모와 태아를 동시에 고려해야 한다는 점 때문에 일반적인 심정지와 다른 부분이 있다. 임신부 심정지 환자에서는 태아를 분만해야 하는지를 결정하는 것은 산모와 태아 모두를 위하여 매우 중요하다. 심폐소생술이 수행되더라도 임신부 심정지 환자가 모두 소생되는 것은 아니며, 얼마나 신속하고 정확하게 심폐소생술이 시행되었느냐에 따라 환자의 생존율이 결정된다. 임신부 심정지 환자는 30세 목격당시 보호자에 의한 빠른 인지와 신속한 신고 및 목격자 심폐소생술이 이루어져 졌으며 119구급대에 의한 전문소생술이 적용되었고, 환자와 태아 모두 적절한 치료 후 6일 만에 건강하게 퇴원한 사례이다. 병원 전 단계에서 임신부 환자가 자발순환회복(Return of spontaneous circulation, ROSC)되어 이송하는 경우와 전문심장구조술을 시행 하는 경우는 매우 드물다. 임신부 심정지가 발생하여 목격자에 의한 심폐소생술과 119구급대원에 의한 전문심장소생술로 현장에서 자발순환회복되어 생존퇴원한 1례를 경험하여 문헌고찰과 함께 보고하는 바이다.

  • 심폐소생술이란 인공호흡과 순환보조를 통하여 조직으로의 산소 공급을 유지하여 임상적 사망에서 생물학적 사망으로 진행을 막고, 심장박동과 순환을 회복시켜 환자를 소생시켜주는 술기이다. 심폐소생술이 시행되더라도 모든 심장정지 환자가 소생되는 것은 아니며, 얼마나 신속하고 정확하게 심폐소생술이 시행되었느냐에 따라 환자의 생존률이 결정된다. 현장에서 심장정지가 목격되지 않은 환자는 병원이송 전 현장에서 2분간 5주기 심폐소생술을 수행하고 자동제세동기를 사용하도록 하였고, 목격된 환자에게는 즉시 자동제세동기를 사용할 것을 권장하고 있으며 이후 전문적인 심장구조술이 필요하다. 병원 전 단계에서 119 구급대가 이송한 환자 중 자발순환회복(return of spontaneous circulation, ROSC)되어 이송하는 경우와 전문심장구조술을 시행 하는 경우는 매우 드물다. 현장에서 심장정지가 목격되었으나 심폐소생술이 시행되지 않았고 구급대원이 도착한 후 심폐소생술 시행 및 전문심장구조술로 현장에서 자발순환회복되어 생존퇴원한 1례를 경험하여 문헌고찰과 함께 보고하는 바이다.

  • The purpose of this study was to predict successful defibrillation in ventricular fibrillation using parameters extracted by wave analysis method and neuro-fuzzy. Total 15 dogs were tested for predicting successful defibrillation. Feature parameters were extracted for return of spontaneous circulation (ROSC) and non-ROSC by wave analysis method, and these parameters are an irregularity factor, spectral moments, mean power of level-crossing spectrum, and mean of alpha-significant value. Additionally, two parameters by analyzing method of frequency were extracted into a mean of power spectrum and a mean frequency. Then extracted parameters were analyzed in which parameters result to have high performance of discriminating ROSC and non-ROSC by a statistical method of t-test. The average of sensitivity and specificity were 62.5% and 75.0%, respectively. The average of positive predictive factor and negative predictive factor were 61.2% and 75.8%, respectively.

  • Cardiopulmonary resuscitation (CPR) is a series of life-saving actions that improve the chances of survival, following cardiac arrest. Successful resuscitation, following cardiac arrest, requires an integrated set of coordinated actions represented by the links in the Chain of Survival. The links include the following: immediate recognition of cardiac arrest and activation of the emergency response system, early CPR with an emphasis on chest compressions, rapid defibrillation, effective advanced life support, and integrated post-cardiac arrest care. The newest development in the CPR guideline is a change in the basic life support sequence of steps from "A-B-C" (Airway, Breathing, Chest compressions) to "C-A-B" (Chest compressions, Airway, Breathing) for adults. Also, "Hands-Only (compression only) CPR" is emphasized for the untrained lay rescuer. On the basis of the strength of the available evidence, there was unanimous support for continuous emphasis on high-quality CPR with compressions of adequate rate and depth, which allows for complete chest recoil, minimizing interruptions in chest compressions and avoiding excessive ventilation. High-quality CPR is the cornerstone of a system of care that can optimize outcomes beyond return of spontaneous circulation (ROSC). There is an increased emphasis on physiologic monitoring to optimize CPR quality, and to detect ROSC. A comprehensive, structured, integrated, multidisciplinary system of care should be implemented in a consistent manner for the treatment of post-cardiac arrest care patients. The return to a prior quality and functional state of health is the ultimate goal of a resuscitation system of care.
