Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) has recently gained popularity as an adjunct to resuscitation of patients with traumatic shock. However, the effectiveness of REBOA is still debated because of inconsistent indications across centers and the lack of medical records. The purpose of this study was to investigate the effectiveness and feasibility of REBOA by analyzing clinical results from a single center. Methods: This study included 96 patients who underwent REBOA between August 2016 and September 2021 at a regional trauma center according to the center's treatment algorithm for traumatic shock. Medical records, including the time of the decision to conduct the REBOA procedure, time of operation, type of aortic occlusion, and clinical outcomes, were collected prospectively and analyzed retrospectively. Patients were classified by REBOA protocol (group 1, 2, or 3) and survival status (survivor or non-survivor) for analysis. Results: The overall success rate of the procedure was 97.9%, and the survival rate was 32.6%. In survivors, blood pressure was higher than in non-survivors both before the REBOA procedure (p=0.002) and after aortic occlusion (p=0.03). The total aortic occlusion time was significantly shorter (p=0.001) and the proportion of partial aortic occlusion was significantly higher (p=0.014) among the survivors. The non-survivors had more acidosis (p<0.001) and higher lactate concentrations (p<0.001) than the survivors. Conclusion: REBOA may be a feasible bridge therapy for resuscitation of patients with traumatic shock. Prompt and accurate decision-making to perform REBOA followed by damage control surgery could improve survival rates and clinical outcomes.

Purpose: Tracheobronchial injuries caused by trauma are rare, but can be life threatening. The objective of this study was to evaluate the surgical outcome for patients with tracheobronchial injuries and to determine the difference, if any, between the outcomes for patients with penetrating trauma and those for patients with blunt trauma. Methods: From January 2010 to June 2015, 40 patients underwent tracheobronchial repair surgery due to trauma. We excluded 14 patients with iatrogenic injuries, and divided the remaining 26 into two groups. Results: In the blunt trauma group, injury mechanisms were motor vehicle accident (9 cases), free falls (3 cases), flat falls (1 case) and mechanical injury (1 case). In the penetrating trauma group, injury mechanisms were stab wounds (10 cases), a gunshot wound (1 case) and a stab wound caused by metal pieces (1 case). The mean RTS (Revised Trauma Score) was $6.89{\pm}1.59$ (range: 2.40-7.84) and the mean ISS (Injury Severity Score) was $24.36{\pm}7.16$ (range: 11-34) in the blunt group; the mean RTS was $7.56{\pm}0.41$ (range: 7.11-7.84), and the mean ISS was $13{\pm}5.26$ (range: 9-25) in the penetrating trauma group. In the blunt trauma group, 9 primary repairs, 1 resection with end-end anastomosis, 2 lobectomies, 1 sleeve bronchial resection and 1 pneumonectomy were performed. In the penetrating trauma group, 10 primary repairs and 2 resections with end-end anastomosis were performed. Complications associated with surgery were found in one patient in the blunt trauma group, and one patient in the penetrating trauma group. No mortalities occurred in either groups. Conclusion: Surgical management of a traumatic tracheobronchial injury is a safe procedure for both patients with a penetrating trauma and those with a blunt trauma.
A law revised in May 2012 provided support to regional and emergency centers for reducing the risk of preventable deaths. In particular, regional trauma centers have been established throughout the nation, with the goal of ensuring that any trauma patient can reach a trauma center within an hour. As a multidisciplinary approach is particularly important in treating severe trauma patients, activation teams are currently organized at each center to perform multiple simultaneous treatments. Under the present system, only 7 departments can participate in these trauma teams; emergency medicine, cardiothoracic surgery, general surgery, orthopedic surgery, neurosurgery, radiology, and anesthesiology. Plastic surgeons also play an essential role in treating trauma patients, and in fact currently treat many such cases. Especially in reconstruction procedures in patients with head and neck trauma and wide tissue defects, plastic surgeons possess unique expertise. However, since plastic surgeons are excluded from the trauma response teams due to institutional limitations, we describe the role and necessity of plastic surgery for trauma and emergency patients, and urge that the system be improved.

Purpose: Preventable Trauma Death Rate (PTDR) using Trauma and Injury Severity Score (TRISS) has been most widely used as a quality indicator in South Korea. However, this method has a small number of deaths corresponding to the denominator. Therefore, it is difficult to check the change of quality improvement for annual mortality, and there is a disadvantage that variation is severe. Therefore, we attempted to improve the quality of the mortality evaluation by reducing the variation by applying the PARK Index (preventable major trauma death rate, PMTDR) which can increase the number of denominator significantly. And the Save score (S-score) was also examined as another quality indicator. Methods: In the PARK Index, the denominator is number of all patients who have survival probability (Ps) larger than 0.25. Numerator is the number of deaths among these. The PARK Index includes only patients with ISS >15. The S-score is calculated in the same way as the W-score, but the S-score includes only patients with ISS >15, which is a difference from the W-score. Results: PARK Index decreased annually and was 12.9 (37/287) in 2014, 9.6 (33/343) in 2015, and 7.3 (52/709) in 2016. S-score increased annually and was -0.29 in 2014, 4.21 in 2015, and 8.75 in 2016. Conclusions: PARK Index and S-score improved annually. This shows that both quality indicators are improving year by year. PARK Index (PMTDR) has 9.5-fold increase in denominator overall compared to PTDR by TRISS. The S-score used only ISS >15 patients as a denominator. Therefore, there is an advantage that the numerical value change is larger than the W-score. In addition, S-score is not affected by the ratio of major trauma patients to minor trauma patients.

Purpose: The purpose of this study was to determine the influence of seasons and weather on the volume of trauma patients in central Korea. Methods: The records of 4,665 patients treated at Chungbuk National Hospital Regional Trauma Center from January 2016 to December 2019 were retrospectively reviewed. Meteorological data including hourly temperature (℃), precipitation (mm), humidity (%), and wind speed (m/s) for each district were collected retrospectively. Statistical analysis was done using the independent t-test, one-way analysis of variance (ANOVA), and linear regression analysis. Results: Patients' average age was 53.66 years, with a significant difference between men (49.92 years) and women (60.48 years) (p<0.001). Rolling/slipping down was a prominent cause of injury in winter (28.4%, n=283), with statistical significance (p<0.001). Trauma occurred least frequently in winter (p=0.005). Linear regression analysis revealed an increasing number of patients as the temperature increased (p<0.05), the humidity increased (p<0.001), and the wind speed decreased (p<0.001). Precipitation did not affect patient volume (p=0.562). One-way ANOVA revealed a decreased incidence of trauma when the temperature exceeded 30℃ (p<0.001), and when the humidity was more than 75%, compared to 25-50% and 50-75%. Conclusions: At the regional trauma center of Chungbuk National University Hospital, in central Korea, the number of trauma patients was lowest in winter, and patient volume was affected by temperature, humidity, and wind speed.
Purpose: Although the Advanced Trauma Life Support (ATLS) course is now taught internationally, it has not been implemented in Korea. In recent years, interest has increased in simulation as a teaching tool in the ATLS course. We therefore hypothesized that simulation training would be a useful adjunct to the ATLS course. Methods: We designed a 1-day curriculum that included skill development workstations, expert lectures, trauma patient simulations, and group discussion for general surgery residents. We conducted a survey to evaluate participants' level of understanding of the initial evaluation and treatment of trauma patients, their degree of knowledge and technical improvement, their satisfaction with the learning goals, and their overall satisfaction with the curriculum. We then analyzed the effects before and after the training. Results: Nine residents attended this course. None of the residents initially reported that they could perform a primary survey of trauma patients. The analysis revealed significant improvements after training in the questionnaire areas of "assembly of the team and preparation for resuscitation of a trauma patient" (p=0.008), "performance of a primary survey for trauma patients" (p=0.007), "resuscitative procedures for trauma patients" (p=0.008), "importance of re-evaluation" (p=0.007), "identifying the pitfalls associated with the initial assessment and management" (p=0.007), and "importance of teamwork" (p=0.007). Conclusions: After the ATLS simulation training, all participants showed significant improvements in their understanding of how to manage multiple trauma patients. Therefore, ATLS simulation training for residents will help in the management of trauma patients.

Background: Cardiac troponin I (cTnI) is a sensitive cardiac marker of myocardial injury. In normal coronary angiogram, positive cTnI values may be detected in various events such as sepsis, stroke, trauma and so on. To investigate characteristics of cTnI positive group in trauma patients, we designed this study between cTnI positive group and cTnI negative group. Method: Trauma patients who visited emergency room within 24 hours after accidents were included. Patients who had renal failure, acute coronary syndrome, sepsis, spontaneous SAH were excluded. Retrospective study of 97 trauma patients was done. We investgated ISS (injury severity score), positive cTnI, EKG abnormality, shock class, ICU admission rate and mortality. Result: In comparing with non chest trauma group, chest trauma group, whose chest AIS (Abbreviated Injury Score) is more than 3 point, had significant values in ISS, positive cTnI, EKG abnormality, shock class and ICU admission rate. Also, in non chest trauma group, we found several patients whose cTnI level was positive. When non chest trauma group was divided into two subgroups, the mortality and shock class of positive cTnI group were higher than that of negative cTnI group. When all trauma patients were divided into two groups, a positive cTnI group had higher values in ISS, shock class, ICU admission rate and mortality than that in a negative cTnI group. Conclusion: We found that cTnI were positive in patients of cardiac contusion but also in various trauma cases. In non chest trauma patients, we assumed that hypotension caused cTnI elevating. The cTnI could play a role in predicting prognosis in trauma patients.

Purpose: Ongoing treatment and care, as well as initial stabilization, are required for trauma patients. With increasing number of sickest trauma patients and shortage of surgeons, the need for advanced practice nurse to provide and coordinate trauma care has been greater. The purpose of this study is to analyze the effect of hiring a trauma clinical nurse specialist and its influence on the treatment of trauma patients. Methods: Based on the employment of the clinical nurse specialist in December 2010, the patients were divided into two groups: patients admitted from January 1, 2010 to November 30, 2010 and patients admitted from December 1, 2010 to December 31, 2011. Retrospectively, data were collected using electronic medical records. The general characteristics, clinical courses, and ICU re-admission rates, collaboration (transfers to other departments and collaborative surgery) were compared. Results: To have a clinical nurse specialist on the trauma team resulted in a statistically significant reductions in the length of general ward hospital stay (p<0.05), the ICU re-admission rate, (p<0.03), the lead-time before transfer to other departments (p<0.05). Conclusion: The clinical nurse specialist, as a professional practitioner, improved the quality of treatment through early detection and management of problems. In addition, as a coordinator, the clinical nurse specialist maintained a cooperative relationship with multi-disciplinary medical personnel. The trauma clinical nurse specialist contributed to the treatment of trauma patients positively through a decrease in ICU re-admission rate and length of hospital stay.
Purpose: The incidence of multiple trauma is increasing nowadays and is the leading cause of death among young adults. Initial treatment is well known to be crucial in multiple trauma victims. However, many indiscriminate transfers occur due to the lack of a well-organized trauma system in Korea. The objective of this study is to demonstrate the current serious state in which major trauma patients are transferred to the Emergency Medical Center of a university hospital from another medical center. Methods: From November 2009 to October 2010, we performed a retrospective study to analyze the characteristics of patients who visited the Ajou University Medical Center located in Gyeonggi-do. We evaluated the ISS (injury severity score), and a score over 15 point was identified as major trauma. The major trauma patients were separated into two groups according to the visit route, and the characteristics of each group were analyzed. Results: Among the 88,862 patients who visited to the Emergency Medical Center, trauma patients accounted for 19,950, and 343 of them were evaluated as major trauma patients. Among the 343 patients, 170 patients had been transferred from other medical centers. The proportion of males to females was 3.3:1, and the mean ISS was 22.7. The leading cause of trauma was motor vehicle accidents. Of the total 170 patients, 77.6% were admitted to the Intensive care unit and 36.3% underwent surgery. The 170 patients that had been transferred to our medical center, 78.8% were transferred from Gyeonggi-do, 15.3% were transferred from other regions, and 5.9% were miscellaneous. Conclusion: Almost half of the major trauma victims treat at our medical center had been transferred from other medical centers. Establishing a traumatic system, supported by well-organized trauma centers and emergency medical services, that can reduce inappropriate transfers among medical facilities is essential.
Purpose: Traumatic airway injuries have high rates of mortality and morbidity. Thus, we evaluated the clinical results of trauma-related airway-injury patients. Methods: A clinical analysis was performed for patients with airway trauma who were admitted and treated at the Department of Thoracic and Cardiovascular Surgery, Konyang University Hospital from Dec. 2002 to Dec. 2009. Results: Sixteen patients were admitted and treated. Fourteen patients were male, and the ages of the patients ranged from 16 to 75 years. Six cases were penetrating injuries, 4 were traffic-accident injuries. 3 were fall injuries, and. 3 were other blunt trauma injuries. Anato- mic injuries included 14 trachea cases (87.5%), 1 Rt. main bronchus (6.25%), and 1 Lt. main bronchus cases (6.25%). Diagnosis was made by using computed tomography and bronchoscopy. Five patients were treated with an explothoracotomy, and 7 underwent neck exploration with primary repair. Three patients simply needed conservative management, and 1 patient was treated with a closed thoracostomy. The post-operative mortality rate was 6.25 % (1 patient). Conclusion: Airway trauma is dangerous and should be treated as an emergency, so a high index of suspicion is essential for rapid diagnosis and successful surgical intervention in patients with airway injuries.
