RESUMEN
Objective@#The purpose of this study was to identify prognostic factors related to outcomes of out-of-hospital cardiac arrest caused by pesticide poisoning. @*Methods@#This retrospective observational study used countrywide population-based data from the Out-of-Hospital Cardiac Arrest Surveillance of the Korean Centers for Disease Control and Prevention from January 2008 to December 2018. Adult out-of-hospital cardiac arrest (OHCA) patients (over the age of 18) poisoned by a pesticide who experienced cardiac arrest and a subsequent return of spontaneous circulation (ROSC) were included in the study. The primary outcome variables were prognostic factors related to survival at hospital discharge, and the secondary outcome variable was good neurological outcome (Cerebral Performance Categories 1 or 2) at hospital discharge. @*Results@#Three hundred and three patients were enrolled in the study, and 48 (15.8%) survived until hospital discharge (the hospital discharge group), and 255 (84.2%) died in hospital (the in-hospital death group). Fifteen (4.9%) of the 303 study subjects had a good neurological outcome, and 288 (95.1%) had a poor neurological outcome. Multivariate logistic regression showed that sustained pre-hospital ROSC was significantly associated with survival to discharge (adjusted odds ratio [AOR]=3.186; 95% confidence interval [CI], 1.436-7.068; P=0.004) and good neurological outcome (AOR=8.945; 95% CI, 2.974-26.907; P≤0.001). @*Conclusion@#Sustained pre-hospital ROSC is associated with a favorable outcome in cases of OHCA induced by pesticide poisoning.
RESUMEN
Considerable evidence has been published since the 2020 Korean Cardiopulmonary Resuscitation Guidelines were reported. The International Liaison Committee on Resuscitation (ILCOR) also publishes the Consensus on CPR and Emergency Cardiovascular Care Science with Treatment Recommendations (CoSTR) summary annually. This review provides expert opinions by reviewing the recent evidence on CPR and ILCOR treatment recommendations. The authors reviewed the CoSTR summary published by ILCOR in 2021 and 2022. PICO (population, intervention, comparator, outcome) questions for each topic were reviewed using a systemic or scoping review methodology. Two experts were appointed for each question and reviewed the topic independently. Topics suggested by the reviewers for revision or additional description of the guidelines were discussed at a consensus conference. Forty-three questions were reviewed, including 15 on basic life support, seven on advanced life support, two on pediatric life support, 11 on neonatal life support, six on education and teams, one on first aid, and one related to coronavirus disease 2019 (COVID-19). Finally, the current Korean CPR Guideline was maintained for 28 questions, and expert opinions were suggested for 15 questions.
RESUMEN
Objective@#The purpose of this study was to determine the type of video laryngoscope training that is appropriate for emergency medical technicians (EMT) familiar with direct laryngoscopes, to prepare them for tracheal intubation while they are wearing personal protective equipment (PPE). @*Methods@#Thirty-eight healthy EMTs were recruited. The participants underwent two tests with four different laryngoscopes: Macintosh, McGrath, Pentax Airway Scope (PENTAX-AWS), and A-LRYNGO. The first test was conducted just after a lecture without any hands-on workshops. The second test was conducted after a hands-on workshop. In each test, we measured the time required for tracheal intubation, intubation success rate, etc., and asked all the participants to respond to a short questionnaire. @*Results@#The time to complete the insertion of the endotracheal tube with the Macintosh laryngoscope did not significantly change (P=0.098), but the rest of the outcomes significantly improved after the hands-on workshop (all P<0.05). Despite the unfamiliarity of the practitioners with video laryngoscopes and their wearing PPE, intubation-related performances were good with the two-channel type video laryngoscopes after the hands-on workshop (all P<0.05). @*Conclusion@#In preparation for an infectious disease pandemic such as the coronavirus disease 2019 (COVID-19), it would be reasonable to train EMTs who would be wearing PPE on the procedure for intubating a trachea with a channeltype video laryngoscope.
RESUMEN
Objective@#This study aimed to analyze the association between the culprit artery and the diagnostic accuracy of automatic electrocardiogram (ECG) interpretation in patients with ST-segment elevation myocardial infarction (STEMI). @*Methods@#This single-centered, retrospective cohort study included adult patients with STEMI who visited the emergency department between January 2017 and December 2020. The primary endpoint was the association between the culprit artery occlusion and the misinterpretation of ECG, evaluated by the chi-square test or Fisher exact test. @*Results@#The rate of misinterpretation of the automated ECG for patients with STEMI was 26.5% (31/117 patients). There was no significant correlation between the ST segment change in the four involved leads (anteroseptal, lateral, inferior, and aVR) and the misinterpretation of ECG (all P > 0.05). Single culprit artery occlusion significantly affected the misinterpretation of ECG compared with multiple culprit artery occlusion (single vs. multiple, 27/86 [31.3%] vs. 4/31 [12.9%], P = 0.045). There was no association between culprit artery and the misinterpretation of ECG (P = 0.132). @*Conclusion@#Single culprit artery occlusion might increase misinterpretation of ECG compared with multiple culprit artery occlusions in the automatic interpretation of STEMI.
RESUMEN
Objective@#Overcrowded emergency departments (ED) are a worldwide problem, which could cause treatment delays and increased mortality of patients. This study aimed at evaluating the effect of admission decisions by emergency physicians without consultation of an internal medicine doctor on the emergency department length of stay (ED LOS) and survival rate of patients diagnosed with medical disease. @*Methods@#The study was a retrospective observational study comparing the ED LOS of patients admitted to the internal medicine (IM) department before and after the policy change regarding admission decisions, implemented in July 2017. During and after the policy change, emergency physicians took decisions on the arrangements and treatment for patients by processing their admission and providing follow-up care without further specialist consultations. The ED LOS and rate of admission to the IM department were compared between the study period (October 2017 to October 2018) and the control period (June 2016 to June 2017). @*Results@#The median ED LOS of patients admitted to the IM department decreased from 164.0 minutes (interquartile range [IQR], 118.0-234.0) in the control period to 114.0 minutes (IQR, 104.0-208.0) in the study period. After propensity score matching, the median ED LOS of patients admitted to the IM department decreased from 187.0 minutes (IQR, 136.0-253.0) in the control period to 144.0 minutes (IQR, 104.0-208.0) in the study period. @*Conclusion@#The admission decisions made by emergency physicians reduced the ED and hospital LOS of patients visiting the ED and diagnosed with medical disease.
RESUMEN
Objective@#This study aimed to evaluate the efficacy of a bougie and glidescope video laryngoscope (GVL) for ground intubation by novice prehospital caregivers. We hypothesized that the intubation outcome using a bougie or GVL was superior to that using the Macintosh laryngoscope (MCL) with a stylet (MCLS) in ground intubation. @*Methods@#A randomized crossover manikin study was conducted. Studied groups were categorized into 4 according to the intubation devices used; MCLS, Macintosh laryngoscope with bougie (MCLB), glidescope video laryngoscope with a stylet (GVLS), and glidescope video laryngoscope with bougie (GVLB). The primary outcome was the total endotracheal intubation time and the secondary outcome was the success rate for endotracheal intubation. @*Results@#The use of a bougie did not cause a significant difference in the intubation time (MCLS vs. MCLB, P=0.213; GVLS vs. GVLB, P=0.633) and the success rate of endotracheal intubation (MCLS vs. MCLB, P>0.990; GVLS vs. GVLB, P=0.077) was compared with the use of a stylet in MCL and GVL. The use of GVL showed a longer endotracheal intubation time compared with MCLS (MCLS vs. GVLS, P<0.001; MCLS vs. GVLB, P<0.001). GVLB showed a decreased success rate of endotracheal intubation compared with the use of MCL (MCLS vs. GVLB, P=0.004; MCLB vs. GVLB, P<0.001). @*Conclusion@#The use of the GVL and a bougie could not affect the performance of endotracheal intubation on the ground. The use of MCL and a stylet for ground intubation could increase the intubation success rate and shorten intubation time compared with the use of a bougie or the use of GVL.

RESUMEN
Objective@#To evaluate the prognostic factors associated with the sustained return of spontaneous circulation (ROSC) and survival to hospital discharge in traumatic out-of-hospital cardiac arrest (TOHCA) patients without prehospital ROSC. @*Methods@#We analyzed Korean nationwide data from the Out-of-Hospital Cardiac Arrest Surveillance, and included adult TOHCA patients without prehospital ROSC from January 2012 to December 2016. The primary outcome was sustained ROSC (>20 minutes). The secondary outcome was survival to discharge. Multivariate analysis was performed to investigate factors associated with the outcomes of TOHCA patients. @*Results@#Among 142,905 cases of OHCA, 8,326 TOHCA patients were investigated. In multivariate analysis, male sex (odds ratio [OR], 1.326; 95% confidence interval [CI], 1.103–1.594; P=0.003), and an initial shockable rhythm (OR, 1.956; 95% CI, 1.113–3.439; P=0.020) were significantly associated with sustained ROSC. Compared with traffic crash, collision (OR, 1.448; 95% CI, 1.086–1.930; P=0.012) was associated with sustained ROSC. Fall (OR, 0.723; 95% CI, 0.589–0.888; P=0.002) was inversely associated with sustained ROSC. Male sex (OR, 1.457; 95% CI, 1.026–2.069; P=0.035) and an initial shockable rhythm (OR, 4.724; 95% CI, 2.451–9.106; P<0.001) were significantly associated with survival to discharge. Metropolitan city (OR, 0.728; 95% CI, 0.541–0.980; P=0.037) was inversely associated with survival to discharge. Compared with traffic crash, collision (OR, 1.745; 95% CI, 1.125–2.708; P=0.013) was associated with survival to discharge. @*Conclusion@#Male sex, an initial shockable rhythm, and collision could be favorable factors for sustained ROSC, whereas fall could be an unfavorable factor. Male sex, non-metropolitan city, an initial shockable rhythm, and collision could be favorable factors in survival to discharge.
RESUMEN
OBJECTIVE: This study aimed to identify the effects of serum potassium and lactate on neurologic outcomes in out-of-hospital post-cardiac arrest adult patients. METHODS: This study was a single center, retrospective observational study. We recruited out-of-hospital post-cardiac arrest adult patients admitted to an intensive care unit from 2011 to 2017. Primary outcome was good neurologic outcome at discharge. To evaluate the prognostic impact of serum potassium and lactate, univariate and multivariate logistic regression analyses were performed. RESULTS: A total of 57 patients were included in this study. The number of patients with good neurologic outcome was 19 (33.3%). In the univariate analysis, good neurologic outcome patients showed a higher smoking rate, shorter pre-hospital transportation time, higher rate of percutaneous coronary intervention, and lower severity score (all p < 0.05). The good neurologic outcome patients also presented higher pH, lower partial pressure of carbon dioxide, and lower potassium regarding laboratory findings on the first hospital day (all p < 0.05). In the multivariate analysis, the independent factors favoring good neurologic outcome were pre-hospital transportation time (adjusted odds ratio [aOR], 0.82; 95% confidence interval [CI], 0.69–0.97; P=0.019) and lower partial pressure of carbon dioxide on the first hospital day (aOR, 0.95; 95% CI, 0.91–0.99; P=0.034). CONCLUSION: Serum potassium and lactate were not significantly associated with good neurologic outcome in out-of-hospital post-cardiac arrest adult patients. The prognostic factors for good neurologic outcome were pre-hospital transportation time and initial partial pressure of carbon dioxide.

PURPOSE: This study aimed to evaluate the thermal protective function of firefighter clothes and gloves through real scale fire simulations. METHODS: Firstly, the fire simulation by real scale flame was performed for firefighter clothes. A manikin equipped with firefighter clothes was directly exposed to flames which energy average is 84 Kw/m2. for 22 seconds. Heat flux gauges attached on the body measured surface temperature elevation. Secondly, we also performed the other fire simulation by hot plate exposure to firefighter gloves. Firefighter gloves with heat flux gauges exposed hot plate which temperature is 300℃ in both dry and moist conditions. Primary outcome was surface temperature change of manikin body (first simulation) and hand (second simulation) over times. RESULTS: In the first flame simulation, the surface temperature of face and shoulders elevated more rapidly comparing with the other body surface area when initial period of flame shutter open. After 18sec of shutter open, the surface temperature of upper trunk elevated rapildy. After shutter closure, high surface temperature kept continuously on right side of face and left shoulder. In the second hot plate simulation, fingers and palms showed higher surface temperature than the other areas of hands in the both dry and wet conditions. CONCLUSION: This study suggests that the real scale flame enables firefighter clothes to lose their heat protective function suddenly after 18 seconds. Additionally, the protective function of firefighter gloves were relatively weaker in the palmar side of fingers than the other parts of hand. There should be additional study for evaluate thermal protection performance of firefighter clothes. And, further effort for reinforce palmar side of fingers of firefighter gloves should be done.

OBJECTIVE: This study aimed to evaluate the efficacy of i-gel blind intubation (IGI) as a rescue device for definitive airway management in ground intubation for pre-hospital trauma patients. METHODS: A prospective randomized crossover study was conducted with 18 paramedics to examine intubation performance of two blind intubation techniques through a supraglottic airway devices (IGI and laryngeal mask airway Fastrach), compared with use of a Macintosh laryngoscope (MCL). Each intubation was conducted at two levels of patient positions (ground- and stretcher-level). Primary outcomes were the intubation time and the success rate for intubation. RESULTS: The intubation time (sec) of each intubation technique was not significantly different between the two positions. In both patient positions, the intubation time of IGI was shortest among the three intubation techniques (17.9±5.2 at the ground-level and 16.9±3.8 at the stretcher-level). In the analysis of cumulative success rate and intubation time, IGI was the fastest to reach 100% success among the three intubation techniques regardless of patient position (all P < 0.017). The success of intubation was only affected by the intubation technique, and IGI achieved more success than MCL (odds ratio, 3.6; 95% confidence interval, 1.1 to 11.6; P=0.03). CONCLUSION: The patient position did not affect intubation performance. Additionally, the intubation time with blind intubation through supraglottic airway devices, especially with IGI, was significantly shorter than that with MCL.

PURPOSE: This study analyzed the prognostic factors affecting admission in acute alcohol-intoxicated traumatic brain injury (TBI) patients visiting the emergency room. METHODS: A multicenter, retrospective observational study was conducted on 821 acute alcohol-intoxicated adult trauma patients, who visited 10 university hospital emergency centers from April to November 2016. The primary outcome was hospital admission. The secondary outcome was in-hospital mortality. RESULTS: One hundred sixty-eight patients diagnosed with acute alcohol-intoxicated TBI were analyzed. The increase in blood alcohol concentration was associated significantly with a mild decrease in admission (adjusted odds ratio, 0.993; 95% confidence interval, 0.989 to 0.998; p=0.01). Moderate to severe TBI patients showed a significant increase in admission compared to mild TBI patients (adjusted odds ratio, 12.449; 95% confidence interval, 3.316 to 46.743; p < 0.001). CONCLUSION: This study showed that the admission was inversely correlated with the blood alcohol concentration and is correlated directly with the increase in the severity in TBI. Therefore, emergency physicians may be required to identify the severity of TBI rapidly and accurately in acute alcohol-intoxicated trauma patients visiting the emergency room.

PURPOSE: Fire suits are very important protective equipment for firefighters. In fire scene, radiant heat and warmed water invade into conventional protective clothing gap. The safety of firefighters has long been a hot topic in Korea. Nevertheless, there are still lack of researches and investigations for safety of firefighters. We revealed the characteristics of the burn site and the hospitalization of injured firefighters according to the wearing of the conventional and special protective clothing. METHODS: This study analyzed the data obtained from the online survey (ko.surveymonkey.com) from September 19, 2016 to October 21, 2016 for nationwide firefighters who are cooperating with the National Security Agency. 4,891 firefighters responded to the questionnaire and 424 burn victims were reported. The analysis was conducted with 322 except 102 incomplete responders. The obtained data was analyzed with Chi-square test (P<0.05). RESULTS: The most common site of burn injury during firefighting was hand 166 (51.6%) followed by face 79 (24.5%), neck 55 (17.1%) and wrist 49 (15.2%). The number of people wearing conventional protective clothing was 81 (25.2%) and the number of people wearing special protective clothing was 20 (6.2%). The number of people wearing protective gloves was 247 (76.7%). In terms of protective clothing in injured firefighters, special protective clothing showed lower hospitalization rate comparing with conventional protective clothing (24.7% vs. 5.0%, P<0.05). CONCLUSION: The most common site of burn injury in Firefighters is hand. The special protective clothing showed lower hospitalization rate comparing with conventional protective clothing.

PURPOSE: Firefighters are vulnerable to burn injury during firefighting. In extensive fires, conducted heat and radiant heat can cause burn injury even though firefighters are not directly exposed to fire. There has been increasing interest in the health problems of firefighters considerably since Hongje-dong fire of 2001, which claimed the lives of six fireman. However, there have been no studies done on the characteristics of firefighter burn injuries in South Korea. Therefore, we investigated the characteristics of firefighter burn injuries in a burn center. METHODS: A retrospective, single-center research was performed between Jan 2006 to Dec 2015. 24 firefighters came to the burn center. The electronic medical records of patients were reviewed. RESULTS: Flame burns (87.5%) were the major cause of burn in firefighter. All the patients suffered second-degree or third-degree burns. Mean burn size was 6.1±6.7%. 22 of 24 patients were hospitalized and 2 of 22 hospitalized patients admitted to intensive care unit. Mean length of hospitalization was 29.1±23.7 days and mean length of intensive care unit hospitalization was 6.0±1.4 days. The face was the site most commonly burned, representing 25.8% of injuries. The hand/wrist, upper extremity, and neck were the next largest groups, with 19.4, 12.9, 11.3% of the injuries, respectively. CONCLUSION: Firefighter burn injuries occur to predictable anatomic sites with common injury patterns. The burn size was small but, admitted patients need about 30 days of hospitalization.

OBJECTIVE: This study aimed to compare intubation performance between blind intubation through supraglottic airway devices and direct laryngoscopy by novices under manikin simulation. We hypothesized that the intubation time by novices using supraglottic airway devices was superior to that with the Macintosh laryngoscope (MCL). METHODS: A prospective, randomized crossover study was conducted with 95 participants, to evaluate i-gel, air-Q, LMA Fastrach, and MCL devices. Primary outcomes were the intubation time and the success rate for intubation. RESULTS: The i-gel showed the shortest insertion and tube passing time among the four devices; the i-gel and air-Q also showed the shortest total intubation time (all P<0.0083; i-gel vs. air-Q, P=0.03). The i-gel and MCL showed the highest cumulative success rate (all P<0.0083; i-gel vs. MCL, P=0.12). CONCLUSION: Blind intubation through the i-gel showed almost equal intubation performance compared to direct laryngoscopy.

BACKGROUND: Recently the incidence of cardiac arrest in the elderly has been on the rise due to aging and the rapid increase in cardiovascular disease. Nevertheless, there has been only a few studies done regarding the factors affecting return of spontaneous circulation (ROSC) and survival in this population within Korea. We investigated the prognostic factors for ROSC and survival in cardiac arrest patients over 65 years visiting a single local emergency center. METHODS: We conducted a single center retrospective observational study, and 87 elderly patients with cardiac arrest were enrolled. They visited the emergency medical care center via ambulance from November 2013 to October 2014. Primary outcomes were ROSC and survival and the secondary outcome was 100 days cumulative survival rate. RESULTS: The level of potassium was the only significant factor for ROSC. The increase in potassium level reduced the rate of ROSC (odds ratio, 0.64; 95% confidence interval [CI], 0.44-0.92; p=0.01). However, higher potassium level was not related to survival (p=1.00). For the 100 days cumulative survival rate, neither hypokalemia (hazard ratio [HR], 1.1; 95% CI, 0.57-2.38; p=0.66) nor hyperkalemia (HR, 1.5; 95% CI, 0.89-2.59; p=0.11) was related to survival compared to normokalemia. CONCLUSION: The potassium level may be considered a valid prognostic factor for ROSC in elderly patients with cardiac arrest. However, it was unrelated to survival.

Lead aVR ST segment elevation in patients with clinically suspected acute coronary syndrome strongly suggests the possibility of occlusion of the left main coronary artery (LMCA), and stenosis or occlusion in this area can cause severe life-threatening left ventricular dysfunction or malignant arrhythmias. Thus, it could be a sign suggestive of a poor prognosis for patients. In this study, we report on the case of a 67-year-old male who presented to the emergency department with total occlusion of LMCA with ST-segment elevation in only lead aVR, and without ST-segment elevation in other leads.

PURPOSE: In an effort to determine the characteristics of foreign suicides who visit an emergency center, this study analyzed suicidal attempt between natives and foreigners. METHODS: We conducted a retrospective analysis of 1,218 Korean and 149 foreign suicidal attempters who visited a regional emergency center from January 1, 2009 to December 31, 2013. We compared two groups according to age, sex, selected suicidal methods, past psychiatric history, medical examination and treatment acceptance, elapsed time to visit an emergency center after suicidal attempt, emergency center residence time, and hospitalization period. RESULTS: No difference in medical exam acceptance and tetanus vaccination was observed between the two groups. However, we found a difference in hospitalization acceptance. The prevalence rate of psychiatric disorders was lower in foreign suicides, and the refusal rate of psychiatric treatment was higher in foreign patients. CONCLUSION: In foreign suicides, social support including finance is required for easy access to health care service. In addition, more active interdisciplinary cooperation with the department of psychiatry and close observation is needed.
