Purpose: Vascular injuries caused by traffic, industrial accidents and by outside activities have increased in Korea. Especially, vascular injuries to the extremities can lead to limb loss and even mortality if they are not appropriately treated. The aim of the study was to evaluate the surgical outcomes of femoropopliteal vascular management after trauma. Methods: The medical records of 12 patients with femoropopliteal vascular injuries who were treated at Dankook University Hospital from 2011 to 2013 were reviewed. Iatrogenic vascular injuries were excluded. The clinical data including the causes of injury, associated injuries and surgical outcomes were analyzed retrospectively. Results: All patients were male, with a mean age of $46.8{\pm}16.3years$ (range: 26~69 years). The causes of vascular injuries were four traffic accidents, three industrial accidents, two iron plates, one outside activity, one glass injury and one knife injury. The average transit time between the place of the accident place and the emergency department was $3.0{\pm}2.1$ (0.5~12.5) hours, and the average preparation time for surgery was $8.0{\pm}6.7$ (1.7~23.3) hours. The anatomic injuries included the popliteal vessel in seven cases and the femoral vessel in five cases. The average Injury Severity Score (ISS) was $12.0{\pm}5.0$ (5~17), and the average Mangled Extremity Severity Score (MESS) was $5.7{\pm}2.1$ (2~9). The operation methods were four interposition grafts, three end-to-end anastomoses, two direct repairs and three patch angioplasties. One case required amputation of the injured extremity. Conclusion: Early recognition and revascularization of the injured vessel are mandatory to reduce limb loss and to obtain satisfactory outcomes. Therefore, careful/rapid evaluation of the vascular injuries and timely/successful surgical treatment are the keys to salvaging an injured limb.

교통사고는 단일요인에 의해 발생하기도 하지만 대부분 다양한 요인이 복합적으로 작용하여 교통사고의 사후분석시 명확한 인과관계를 규명하는데 어려움이 있다. 본 연구에서는 초보운전자에 의한 교통사고를 대상으로 교통사고의 심각도에 영향을 주는 요인들에 대해 분석하였다. 사고발생 시 인명피해가 큰 보행자-차량 교통사고의 사고 심각도를 종속변수로 설정하고 사고 심각도의 증가에 유의한 영향을 미칠 것으로 판단되는 성별, 연령, 교통법규위반 횟수, 교통사고위치 등의 운전자 특성에 관련된 각종 변수들을 독립변수로 설정하여 운전자 운전 경력에 따라 분류하였다. 이항 로지스틱 회귀분석(BLR)을 적용하여 운전경력별 사고심각도 영향 요인을 도출하였다. 분석결과, 운전경력 그룹에 관계없이 운전자 연령, 교통법규위반 횟수, 교통사고위치가 보행자-차량 교통사고 심각도 증가에 영향을 미치는 것으로 나타났다. 본 연구에서 제시한 교통사고 심각도에 영향을 미치는 운전자 특성은 향후 운전자 인적 특성과 더불어 도로환경 및 차량관련 요소에 관련된 교통사고 심각도에 영향을 미치는 요인 분석에 효과적으로 사용될 것으로 기대된다.

Purpose: In this study, we aimed to compare the characteristics of patients with trauma by age group in a single center in Korea to identify the clinical characteristics and analyze the risk factors affecting mortality. Methods: Patients aged ≥18 years who visited the Chungbuk National University Hospital Regional Trauma Center between January 2016 and December 2022 were included. The accident mechanism, severity of the injury, and outcomes were compared by classifying the patients into group A (18-64 years), group B (65-79 years), and group C (≥80 years). In addition, logistic regression analysis was performed to identify factors affecting death. Results: The most common injury mechanism was traffic accidents in group A (40.9%) and slipping in group B (37.0%) and group C (56.2%). Although group A had the highest intensive care unit admission rate (38.0%), group C had the highest mortality rate (9.5%). In the regression analysis, 3 to 8 points on the Glasgow Coma Scale had the highest odds ratio for mortality, and red blood cell transfusion within 24 hours, intensive care unit admission, age, and Injury Severity Score were the predictors of death. Conclusions: For patients with trauma, the mechanism, injured body region, and severity of injury differed among the age groups. The high mortality rate of elderly patients suggests the need for different treatment approaches for trauma patients according to age. Identifying factors affecting clinical patterns and mortality according to age groups can help improve the prognosis of trauma patients in the future.

Purpose: Crushing injuries by car tires result from a combination of friction, shearing, and compression forces and the severity of injury is influenced by the acceleration. Because car-tire injuries of the lower leg in children are common these days but they have received little attention; thus, our purpose was to look closely into this problem. Methods: A retrospective analysis was conducted of data from children under 15 years old age who visited an emergency department because of a car-tire-related crushing injury to the lower leg in pedestrian traffic accident from January 2008 to September 2012. The patient's age, sex, site of injury, degree of injury, associated injuries, type of surgery, and complications were reviewed. Results: There were 39 children, the mean age was 8.0 years, and 71.8% were boys. The dorsal part of the leg was involved most frequently. According to the severity classification, 15 children were grade I, 6 were grade II, and 18 were grade III. Among 24 patients, 13 were treated with skin graft and 3 were treated using a sural flap. Twelve patients developed complications, such as hypertrophic scarring, contractures, and deformities with significant bone loss. Conclusion: Various degrees of skin or soft tissue defects were caused in children by car tires. In this study, patients were often also had tendon or bone damage. Proper and timely initial treatments are needed to reduce the incidence of infection, the number of operative procedures, and the hospital stay.

Purpose: The purpose of this study is, first, to analyze the risk factors that influence the severity of injury in pediatric multiple trauma patients and, second, to present solutions for the problems related to the treatment of such patients. Our living situations are so complicated that the danger of accidents is truly open to children who are not prepared. We need to draw attention to the increased numbers of various accidents involving children. Methods: We studied patients who visited the Emergency Medical Center at Chosun University Hospital from January 1, 2006, to December 31, 2008. Using medical records, we evaluated the general characteristics: the mechanism of injury, the vital signs, the revised trauma score (RTS), the injury severity score (ISS), and the hemoglibin value, which was checked at the time of visit, and the presence or the absence of emergent on regular surgery. We divided the level of injury as follows: light level (1-8 points), mid level (9-15 points), and serious level (above 16 points). We analyzed the medical data by using SPSS 17.0 for windows. Results: The average age of the patients examined was 8.6 years. The number of 6- to 11-year-old patients was 96, which was the largest, but the degree of injury severity was the highest among infant (0-2 years), according to ISS 7.95(${\pm}6.85$). The frequency of accidents was highest on sunny days, and most accidents occurred from 16:00 to 20:00. The cause of multiple trauma for children was the greatest in the traffic accident, (95 patients, 49.0%). In addition, the trauma caused by traffic accidents showed the highest ISS value ($9.02{\pm}6.42$) and the most serious degree (P=0.004). The ISS level of injury ($8.40{\pm}6.64$) for patients moved from a secondary hospital was higher than that ($6.49{\pm}5.57$) for patients who visited the medical center directly. The severity of injury was highest for patients who used a 119 ambulance ($8.84{\pm}5.80$). According to the injured parts of body, Injuries to the arms and the feet most frequent (79 patients, 40.7%), but the level of injury was the highest for internal organs and chest, $16.42{\pm}8.56$ and $11.23{\pm}6.97$, respectively. Conclusion: We used Abbreviated Injury Scale (AIS) in order to examine the characteristics by injured body part for pediatric multiple trauma patients. Because the degree of injury was the highest for internal organs or the chest, we need to more seriously examine and provide for patients who are suspected of having injuries to the internal organs or the chest. We need to quickly determine the need for surgery in patients with serious injuries to the arms and the feet, which is the greatest in frequency. In particular, we need to consider the surgical care of patients who are not very high in the severity of injury to their brains.

Subclavian injuries in blunt trauma are reported in less than 1% of all arterial injuries or chest related injuries. We report a female 68 yr-old patient whom has visited our emergency center due to a motorcycle traffic accident with complaints of right chest wall and shoulder pain. Her injury severity score was 22 and she was found with a comminuted clavicle fracture and subclavian artery injury. She developed delayed symptoms of pallor, pain and motor weakness with loss of pulse in her right arm. Attempts at intervention failed and thus, she underwent emergency artificial graft bypass from her subclavian artery to her brachial artery. Her postoperative course was uneventful and she is happy with the results. Although rare, a high index of suspicion for the injury must be noted and the inevitable surgical option must always be considered.

The work analyzes the existing situation and defines special problems concerning traffic accidents in the two countries. The report is divided into three parts: 1) Using the global approach of SMEED, the data were evaluated using multiple regression analysis, and homogeneous groups of countries were defined by cluster analysis. In the global approach, the linear model is better than SMEED's non-linear model in explaining the number of fatalities. Among the different groups of countries, the linear approach was found to be better suited for industrialized countries and the non-linear approach better for the developing countries. T도 comparison of traffic fatality data for the Federal Republic the developing countries. The comparison of traffic fatality data for the Federal Republic of Germany and the Republic of Korea showed different regression equations during the same time period. 2) The BOX/JENKINS time series analysis on a monthly basis points out clearly similar seasonal patterns for the two countries over the years studied. The decrease in traffic accidents following the intensification of the safety belt requirement was proved in the ARIMA model. It amounts to 7 to 8 percent fewer personal injury accidents and fatal accidents. The identified increase in safety in the Federal Republic of Germany since the 1970s is mainly due to the reduction of accident severity in residential areas. 3) Speeds and headways on motorways in th3e two countries were also compared. The measurements point out that German road users drive faster, take more risks, and accept shorter time gaps than Korean road users. However, the accident statistics show accident rates for Korea that are several times higher than those in the Federal Republic of Germany.
