Purpose: It is crucial that 119 emergency medical technician (EMT) have adequate knowledge regarding forensic science. This study aimed to assess the forensic knowledge of EMTs in the Republic of Korea. Methods: This study was conducted on EMTs of five fire stations in D metropolitan city between August 6 and August 13, 2018. A questionnaire consisting of items on crime-related incident recognition (i.e., mechanical asphyxiation, trauma, sex crimes, and child abuse), forensic evidence management (i.e., evidence collection, preservation, and recording) was administered to the participants. Finally, 119 questionnaires were analyzed. Results: The ratio of correct answers for crime-related incidents recognition was 55.82%, which was lower than that for forensic evidence management(84.5%). In particular, the scores for the type of neck compression(16.5%) and wound assessment(44.0%) were low. The percentage of correct answers for forensic evidence management was 78.4% for evidence collection, 84.4% for evidence preservation, and 90.6% for evidence recording. Previous forensic education experience was not a significant variable. Conclusion: Specific and practical forensic science education on perception of crime-related incident, including asphyxia and wound identification, and forensic evidence collection is needed.

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.

응급의료전화상담원의 도움에 의해 교육 받지 않은 목격자의 제세동 시행 후 생존한 병원 전 심정지 1례

김종호(Jong-Ho Kim),문준동(Jun-Dong Moon) 한국산학기술학회 2018 한국산학기술학회논문지 Vol.19 No.4

59세의 기왕력 및 가족력에 특이사항이 없는 남자가 가슴통증을 호소하다 의식을 잃고 쓰러지자 이를 목격한 가족이 119에 신고하였다. 응급의료상담원의 도움에 의해 목격자가 심폐소생술을 시행하였고 거주 중인 아파트에 설치된 자동심장충격기를 이용하여 제세동 1회를 시행하였다. 이후 도착한 119구급대에 의해 제세동 2회 실시 후 자발순환회복되어 인근 응급의료센터로 이송되었으며, 저체온 치료 15일 후 대뇌수행분류 1점으로 퇴원하였다. 현재 우리나라의 응급의료전화상담원 도움에 의한 목격자 심폐소생술 및 제세동의 시행은 시작 단계이지만 본 증례를 통해 충분한 효과를 볼 수 있다고 판단되며, 이에 따라 응급의료전화상담원의 적극적인 자동심장충격기 사용 안내와 그에 맞는 체계적인 교육이 필요하다. 특히 훈련받지 않은 목격자의 자동심장충격기의 사용을 도울 수 있고, 119구급대가 현장까지의 반응시간이 지연되는 원거리 지역에서 중요한 의미를 가질 것으로 사료된다. 또한 우리나라 PAD 프로그램의 양적인 보급뿐만 아니라 목격자의 접근성을 높일 수 있는 방안이 될 것이다. A 59-year-old man with no specific medical or family history complained of chest pain and became unconscious. A member of his family, who was a witness called 119 and gave him dispatcher-assisted cardiopulmonary resuscitation, followed by defibrillation using an automated external defibrillator placed in his apartment. Afterward, he was given two sessions of defibrillation by the 119 emergency squad, then transferred to an emergency medical center with the return of spontaneous circulation. The patient was discharged with cerebral performance category (CPC) 1 15 days later. While dispatcher-assisted cardiopulmonary resuscitationand defibrillation is at its beginning stage in South Korea, this case seems to demonstrate its effectiveness. Moreover, this case suggests it can be particulary useful for helping untrained witnesses use an automated external defibrillator, which may have importnat implications in regions in which there are delayed responses of the 119 emergency squad to the site. It is also important to develop a plan for improving witness access to and quantitative supply of the South Korean public access defibrillation (PAD) program.

본 연구는 응급구조학과 학생들의 구급차 동승실습으로 구축된 구급활동일지를 바탕으로 응급환자의 지역별 특성을 파악하고, 지역 간의 출동거리와 현장도착시간 간에 의미있는 영향이 있는 지를 알아보고자 하였다. A대학 4학년 학생 총 31명이 서울, 대전, 충남 및 세종지역의 소방서에서 4주간의 실습으로 얻어진 총 1133개의 구급활동일지를 후향적으로 분석하였다. 연구결과 환자평가 중 맥박, 호흡수, 산호포화도는 모든 지역에서 80%이상을 실시하고 있었다. 중증도 분류에 있어서는 대전이 응급으로 표시한 경우가 가장 많았으나 환자에 대한 응급처치는 모든 지역에서 단순한 기본적인 처치가 대부분이었다. 신고부터 현장까지 도착하는 시간은 서울이 평균 5분 40초(±2분 25초)로 가장 빨랐고, 충남세종은 10분 이상 걸리는 경우도 35.7%에서 나타났다. 주된 신고 이유는 서울과 대전에서는 질병이었고, 충남은 손상의 비율이 높았다. 이러한 결과는 응급구조학과 학생들의 실습지역에 따라 실습내용이 다소 차이가 있을 수 있어 실습기준에 대한 표준지침이 필요할 것으로 사료되며, 빠른 시간내에 적절한 응급처치를 받을 수 있는 119 안전센터의 배치나 구급차 배치를 고민하고, 지역별 구급의 질 적 차이를 최소화하기 위해 노력해야 할 것이다. Purpose This study is to investigate regional characteristics of 119 ambulance dispatch and the relationship between the distance and response time to the scene. Methods This study was retrospectively conducted 119 running sheets with 1,321 patients who had been transferred to the hospital by 119 ambulance during ambulance attendant training. The training was performed at two, five and three fire station in Seoul, Daejeon and Chungnam respectively, from June 24, 2013 to July 19, 2014. Results Almost the emergency medical services provided were no more than basic first aid in all regions. The patients transferred by 119 ambulance in Seoul were more than other region. The time of call to scene and scene to hospital were the slowest in Chungnam. The major reason of call 119 was due to disease in Seoul and Daejeon, however due to injury in Chungnam. Conclusion Our study suggests that learning from ambulance attendant training course could diverse from region to region. It is, therefore, needed that standardization of ambulance attendant training course, appropriate logistics and resource allocation for providing universal quality of emergency medical services.

Diagostic imaging can help in management of toxicologic emergencies. We report a patient who presented to the emergency department with coma and suppressed respiration after ingestion of unknown substance. We documented chloroform with radiopaque material in bowel on abdominal radiograph. We used activated charcoal and laxative to decontaminate bowel. Hepatotoxicity occurred on 3rd admission day and elevation of liver enzyme reached peak level on 5th admission day. The patient received hemoperfusion, N-acetylsystein and supportive cares. The patient was improved from hepatic dysfunction and discharged without complication on 11th admission day. Radiograph in toxicology may confirm a diagnosis and assist in therapeutic intervention.

Background: This study's objective was to determine the prognostic value of the base deficit measured in the emergency department(ED) and to determine whether base deficit can provide information not provided by advanced injury scoring system. Methods: This study was a retrospective analysis of data collected for two years. Thirty-two severe trauma patients who were admitted to the Emergency Department of Korea University Hospital were included in this study. The patients were divided into two groups: the normal base deficit group(-3 mmol/L to 3 mmol/L) and the elevated base deficit group(>3 mmol/L). The base-deficit value, age, sex, head injury, organ failure rate, and survival were considered, and the also Revised Trauma Score(RTS), Acute Physiology And Chronic Health Evaluation(APACHE II), and Injury Severity Score(ISS) were measured. Result: The elevated base-deficit group showed a lower survival rate and a higher organ failure rate compared to the normal base deficit group. Logistic Regression showed a strong association between base deficit and mortality rate. Among the previous injury scoring Systems(RTS, APACHE II, ISS), base deficit had the strongest correlation with RTS. By using base deficit value and the RTS together, we obtained a higher positive predictive value than that obtained by using base deficit or RTS alone. Conclusion: The admission value of the base deficit in the ED is a useful tool in predicting the outcome in severe trauma patients, and it can be an adjunct to previous injury scoring systems. As an advanced injury scoring System is developed in the future, the base deficit may have some significant role.

Background: It has been documented that certain prognostic factors may affect the outcomes of the old aged victims by trauma. Considering that trauma is the sixth most common cause of death in people over the age of 65 years and there is a rapid growth of elderly population, it is paramount to understand the prognostic factors when dealing with geriatric trauma patients. Hypothesis and Goals: It can be hypothesized that the prognostic factors should be determined independently between populations being consisted of different races, countries, socio-economic states, cultures, or so on. Thus, the study was designed to evaluate the factors affecting the outcomes of elderly Korean trauma patients. Methods: One hundred forty six patients aged over 65 years were retrospectively reviewed, who visited the Emergency Center of Korea University from January, 1997 to June, 1998. Of 146 patients, 7 were excluded due to discharge against advice or transfer to the other hospitals. Parameters analyzed were age, sex, mechanism of injuries, body region injured, Injury Severity Score (ISS), previous medical illness, hospital morbidity, duration of hospital stay, and cost. Each patient was classified into improved or not-improved group depending on the outcomes, and young-old or old-old group depending on the age. The factors affecting the hospital stay in improved patients were analyzed in the parameters of previous medical illness, hospital morbidity, multiple injuries, ISS, and age. All statistical tests were conducted with two-tailed levels of 0.05. Results: Of 139 patients, the mean age was 74±7.1 years, mean ISS 9.3±7.26, mean hospital stay 27±27.1 days. Most commonly injured body region was the extremities due to fall from a level surface. Rate of previous illness showed 0.94 medical diseases per person and were aggravated after trauma in 39 patients (60.9%). Hospital morbidity rate was 0.46 incidents per person. There were no differences in age and duration of hospital stay between the improved and the not-improved group. Substantial differences were noted in affected body region, incidence of previous illness, and hospital morbidity between the groups (p=NS). Not-improved group had higher ISS(p<0.05). ISS, previous illness and hospital morbidity affected the duration of hospital stay in the improved group. Hospital stay was 40±25.1 days in patients with ISS over 6 while 6±8.6 days in those with ISS 5(p<0.05). Hospital stay in the improved was 26±26.9 days while 31±24.8 days in the improved old-old group (p=NS). Hospital stay in the young-old minor trauma (ISS5) patients with previous illness and hospital morbidity was 26±10.1 days while 4±7.3 days in those without previous illness and hospital morbidity (p<0.05). Conclusion: Previous medical illness and hospital morbidity, not age, are predictive of outcomes of geriatric trauma patients with respect to hospital stay. As most of the hospital morbidity was a trauma-induced aggravation of previous medical illness and hospital morbidity contributing poor outcomes can be potentially avoidable, routine aggressive care for the geriatric trauma patients with previous medical illnesses is needed.

Background: We studied the incidence of trauma caused by alcohol related accidents, and the effects that alcohol has on the occurrence, the extent, and the outcome to the patient. Methods: In our study we studied trauma patients excluding pediatric patients(15 years old and under) who came to the Emergency department of Korea University Medical School Anam Hospital from the 1st of January 1996 to 30th of June 1996, looked into their medical records, and studied the records in a retrospective manner. The trauma patients were devided into two groups, a) alcohol-related and b) alcohol-non-related. The two groups were then subdivided according to their sex, age, the time they came in, the anatomical part of the trauma, the mechanism of their injury, the extent of the injury, the length of their hospital stay, the length of their ED stay and were seperately compared and analyzed. Statistically, ANOVA and logistic regression analysis using SAS were used in the study and then was assessed in Chi-square analysis methods. Results: The total of the trauma patients, added up to 832 people, 577:male and 255:female. Among this sum, 163 trauma patients were alcohol related(male:127 & female:36). 115 people were in the age group of 21-40. Compared to the non-alcohol related trauma group, the alcohol-related group had more facial & scalp injuries and tended to come in the hours between 0-6 AM. The cause of the injuries were mostly by fist-fighting and suicide, compared to mostly accidental-slipping injuries in the non alcohol-related group. There were no difference in the degree of the injury(ISS) and the length of hospital stay between the two groups, whereas the length of the stay at the ED was longer to the alcohol-related trauma patients. Conclusion: Alcohol related trauma patients were mostly in their 20s and 30s, came to the hospital at a late time and the reason for their visit were mostly because of fist fighting. In the Emergency department, because prompt and correct diagnosis is quite difficult to make in this group, their ED stay tended to be longer. We can conclude that measuring the blood alcohol level of these patients, continuing the psychological therapy and educating people is needed.

Background: Predicting outcome after head trauma is of great interest for clinicians, especially in the early stage. It may provide a basis for therapeutic strategies and may be helpful to select different approaches. But, reliable outcome prediction from head trauma is still unresolved. The purpose of this study is to determine which clinical parameters can be used effectively after an event of head trauma. Methods: In our study we studied head trauma patients who came to the Emergency department of Korea University Medical School Anam Hospital from the 1st of June 1998 to 31th of January 2000, looked into medical records, and studied the records in a retrospective manner. The head trauma patients were divied into two group, a) favourable outcome-related and b) unfavourable outcome-related. The two groups were then subdivided according to their sex, age, the mechanism of their injury, the time they came in, alcohol drinking, loss of consciousness, vomiting, pupil change, previous medical illness, associated injuries and were seperately compared and analyzed. And the factors affecting Glasgow Outcome Scale(GOS) were analyzed in the parameters of Injury Severity Score(ISS), Revised Trauma Score(RTS), Glasgow Coma Scale(GCS), motor score of GCS(mGCS), Marshall Computed Tomographic Classification(MCTC). Statistically, t-test and Mann-Whistney rank sum test using Jandel-sigma were used in the study and then were assessed in Chi-square analysis methods. The statistical significance was determined at a level of p less than 0.05. Results: The total of the head trauma patients, added up to 129 people, 99:males and 30:females. Among this sum, 99 patients showed a favourable outcome and 30 patients showed an unfavourable outcome at discharge. The causes of injury included: automobile accident in 42 cases; fallss in 26; assaults in 6; and accidental-slipping injury etc in 55 cases. 12 patients had bilateral unreactive pupils on admission, 2 had unilateral reactive pupils, and 113 had bilateral reactive pupils. Compared to the favourable outcome-related head trauma group, the unfavourable outcome-relared head trauma group had more history of loss of consciousness, unreactive pupils and tended to have previous medical illness. There were no difference in alcohol related, vomiting and associated injuries between two groups(favourable outcome-related head trauma group: unfavourable outcome-related head trauma group). Substantial difference were observed in GCS, mGCS, ISS, RTS, MCTC between two groups. Patients with unfavourable outcome had a significantly higher ISS, lower RTS, lower mGCS. After MCTC, patients with mass lesion had unfavourable outcome than patients with diffuse injury. Conclusion: Age, history of loss of consciousness, previous medical illness and unreactive pupil change are predictives of outcomes of head trauma patients with respect to Glasgow outcome scale. The lower GCS, lower RTS, lower mGCS, higher ISS, mass lesion based on CT scan provide poorer prognostic outcome in patients with head trauma. Use of prognostic factors thorough complete history taking and physical examination would provide useful prognostic information and facilitate improved therapeutic decision-malting in head-injuried patients.

외상성 기흉에 동반된 후복막기종 : 증례보고 Case Report

홍윤식,이성우,최성혁,전정민,문철규,문준동 대한외상학회 1998 大韓外傷學會誌 Vol.11 No.1

We describe a 23-year-old patient from blunt injury after motor vehicle accident. The cardiorespiratory and mental status were sufficient. He had pneumoretroperitoneum, left pneumothorax, complex zygoma fracture and left clavicle frature. Close drainage of left hemithorax and the diagnostic workups were done for evaluation of retroperitoneal free air. As free retroperitoneal gas has its source in a ruptured retroperitoneal viscus in common case, close attention was paid to possible abdominal symptoms. Abdominal computed tomography failed to demonstrate any pathology except free air in retroperitoneum. Surgical exploration of intraperitoneun and retroperitoneum wasn't revealed any injury. The patient was discharged after fixation of zygomatic fracture. The underlying pathophysiology of free retroperitoneal air in the absence of viscus and diaphragm lesions are discussed and the literatures are reviewed.
