Purpose: This study aims to analyze the current state of emergency care for patients with anaphylaxis and to identify problems and areas for improvement in prehospital care. Methods: This study was conducted using 119 emergency running sheets and medical records of 109 patients diagnosed with anaphylaxis. Questionnaires were also given to emergency medical technicians (EMTs) and emergency physicians. The data were analyzed using SPSS 21.0. Results: Prehospital emergency care included oxygen administration in 64.2%, an intravenous line in 15.6%, and medication injection in 11.0%. The most commonly administered medications were antihistamines in 66.7% and epinephrine in 8.3%. Of EMTs surveyed, 47.0% suggested an epinephrine injection and using direct medical control, while 53.8% of the emergency physicians suggested an epinephrine injection and using indirect medical control. Most emergency physicians 88.8% responded that epinephrine could be administered by EMTs. Conclusion: The data support epinephrine injection of patients with anaphylaxis by EMTs, but a larger sample size of EMTs is required. Education about the treatment of anaphylaxis should be improved for EMTs. The scope of paramedic responsibilities should also be redefined.

Purpose: This study examined the effect of wearing personal protective equipment (PPE) on cardiopulmonary resuscitation (CPR), positive airway pressure, and the posture of emergency medical technicians (EMTs) when conducting CPR. Methods: Twenty 119 EMTs performed 30:2 CPR on a manikin for 4 min. Imaging data were digitized with Kwon3D XP (version 4.0). Data were collected by analyzing the motion when starting in one cycle, such as pressing to the maximum and in the final position (relaxed), and were analyzed with SPSS 18.0. Results: The angle of the elbow joints was significantly reduced (p < .05). The trunk angle was statistically significantly (p < .01, p < .001) increased. The angular velocities of the shoulder joint and left elbow joint were reduced (p > .05). The angular velocity of the trunk was significantly reduced in the starting and maximum compression postures. The hand-escape time was increased. The average compression depth was increased but not significantly (p > .05). The positive airway pressure was reduced (p > .05). Conclusion: The angle of the elbow joints and the angular velocity of the trunk were reduced, and the angle of the trunk was increased. The success of CPR and positive airway pressure was reduced.

Purpose: This descriptive correlational study investigated the effects of violent experience and resilience on burnout in emergency medical technicians (EMTs). Methods: The participants were 160 EMTs working in fire stations (safety center and local center) located in U, B, and D city. The collected data were analyzed by descriptive statistics, independent t-test, ANOVA, $Scheff{\acute{e}}$ test post-hoc analysis, Pearson correlation coefficients, and multiple regression analysis using IBM SPSS Statistics 20.0. Results: The number of EMTs getting into ambulances was significantly associated with violent experience, resilience, and burnout. Position of EMTs was significantly associated with both resilience and burnout. In the multiple regression analysis, the subscales of durability and optimism in resilience were significantly associated with burnout after controlling for confounding variables. Conclusion: This study indicated that improving durability and optimism in resilience was important to cope with experience of violence and to prevent burnout in EMTs.

Purpose: Advanced airway maintenance improves the quality of cardiopulmonary resuscitation (CPR) for out-of-hospital cardiac arrest (OHCA) patients. In this study, we evaluate the factors associated with advanced airway management while performing CPR for out-of-hospital cardiac arrest patients by 119 emergency medical technicians (EMTs). Methods: The observational analysis method was used ro retrospectively collect data from 119 rescue run sheets. This study was conducted in a fire station in Seoul, Korea. The subjects of this study were defined as OHCA patients who received CPR from July 2016 to June 2018. We divided the subjects into two groups according to whether advanced airway maintenance was performed or not, and then compared and analyzed both groups. We performed logistic regression analyses for characteristics that differed significantly between groups. Results: Out of 188 OHCA patients, 146 (77.7%) had received advanced airway management. Statistically significant differences in the logistic analysis were found regarding the total number of EMT professionals (adjusted odds ration [aOR]: 1.955; 95% confidence interval [CI]: 1.227-3.115; p=0.005) and scene-time (aOR:1.119;95%CI:1.019-1.228;p=0.019). Conclusion: Advanced airway maintenance while performing CPR for OHCA patients by EMT associated primarily with ensuring an adequate numbers of EMT professionals and sufficient scene time.

Purpose: The 2018 General survey of emergency assistance was conducted to examine the working conditions and welfare, including educational direction, interests, and awareness of work, of the fire department emergency medical technicians (EMT). This would be used as basic data for future policy directions. Methods: Among the fire-fighting officers in 16 cities nationwide, emergency rescue workers engaged in first-aid activities were targeted. With prior consent, a survey was conducted through electronic documents. Of the total 1,227 people, responses from 1,151 were finally analyzed, excluding 76 who did not respond appropriately. Results: The working conditions and welfare of 119 firefighters were moderate, but in the fields of education and interest, the learning according to the regulations was high. In particular, satisfaction with the scope of work was found to be below average. However, it was positive that it will play a role as a social safety net in the future and will converge with cutting-edge science. Conclusion: Although this study was a total investigation of the EMT survey, conducting an EMT survey on all fire fighters in Korea is difficult. Further research is needed, particularly on first-class emergency medical personnel who play a major role in 119 paramedics.

Purpose: The purpose of the study was to investigate the correlation between injury and injury severity score (ISS) in geriatric traffic accident patients transported by 119 emergency medical technicians (EMTs). Methods: The subjects were 240 traffic accident patients over 65 years old transported by 119 rescue services emergency departments in Busan from January 1, 2014 to August 31, 2015. Results: ISS increased in motorcycle traffic accidents (p=.026), truck injuries (p=.005), and head and neck injury (p<.001). Vital signs were evaluated by 119 rescue EMT. ISS increased in cases of unresponsive unconsciousness (p<.001), hypotension (p=.001), and bradycardia (p<.001). The need for bleeding control and dressing by the EMTs increased ISS significantly (p=.022). Conclusion: In the initial evaluation of geriatric traffic patients, ISS can increase in motor cycle accidents and truck injuries. Due to high ISS, patients with head and neck injury, chest injury, hypotension, or tachycardia should be transferred to advanced level hospitals.

Purpose: This study intended to improve quality of prehospital emergency care for trauma patients by figuring out its current situations and problems based on run-sheets and questionnaires of 119 emergency medical technicians (EMTs). Methods: This study conducted a research of 425 trauma patients transferred to the 3rd hospital in G-city by 119 ambulances from July 1, 2008 to June 30, 2009. We aslo utilized 114 copies with questionnaires of 119 EMTs working in J-province. The data were analyzed with SPSS 18.0. Results: There were 425 trauma patients including 272 men and 137 patients with traffic accident. When it comes to types of 119 EMTs who delivered cares to patients, there were 206 (48.5%) advanced EMTs, 101 (23.8%) basic EMTs, 50 (11.8%) nurses and 43 (10.2%) rescue education receivers. The most frequent measured vital sign was pulse rate (54.1%). Regarding assessment of systolic blood pressure, pulse rate and respiration rate, there were some significant differences in accordance with type of 119 EMTs. Among the 317 patients evaluated 'emergency' in field, 137 patients returned to their home. Prehospital emergency cares accounted for 861, around 2.0 treatments per a patient. In view of questionnaire, the 74.6% of 119 EMTs hoped supplement of man power for proper prehospital care to trauma patients. Conclusion: This study suggested that it is necessary to develop detailed guidelines for trauma patients so as to improve quality of trauma patient evaluation and prehospital care. Furthermore, improvement of emergency care systems will reduce mortality of trauma patients and lead to their good outcome.

Purpose: The study aimed to collect the first aid activity log data of patients who were retransferred through paramedics and to analyze the data in the hospital to improve the plan. Methods: We analyzed 434 retransferred patients, out of the 18,197 patients who visited the emergency medical center in the C area in G metropolitan city, from January 2017 through December 2018. The collected data were analyzed using the SPSS software. Results: The patients were retransferred for various reasons: 17.7% (77 cases) due to the absence of specialists, 15.0% (65 cases) required first aid, and 5.3% (23 cases) due to absence of medical department. In addition, the major medical department with the largest number of retransfer was the department of emergency medicine with 38.2% (166 cases). In the prehospital stage, 38.5% (167 cases) were classified as severe, but in the hospital stage, they were classified as mild. In addition, as a result of hospitalization and discharge, 60.4% (262 cases) were discharged. Conclusion: Most of the retransferred patients were non-emergency patients, and were discharged for mild conditions. The overcrowding in the emergency room of a tertiary hospital can be prevented by reducing the retransmission.
