Risk of permanent medical impairment after road traffic crashes: A systematic review / 中华创伤杂志(英文版)

PURPOSE@#To systematically review the risk of permanent disability related to road traffic injuries (RTIs) and to determine the implications for future research regarding permanent impairment following road traffic crashes.@*METHODS@#We conducted this systematic review according to the preferred reporting items for systematic reviews and meta-analysis statement. An extended search of the literature was carried out in 4 major electronic databases for scientific research papers published from January 1980 to February 2020. Two teams include 2 reviewers each, screened independently the titles/abstracts, and after that, reviewed the full text of the included studies. The quality of the studies was assessed using the strengthening the reporting of observational studies in epidemiology (STROBE) checklist. A third reviewer was assessed any discrepancy and all data of included studies were extracted. Finally, the data were systematically analyzed, and the related data were interpreted.@*RESULTS@#Five out of 16 studies were evaluated as high-quality according to the STROBE checklist. Fifteen studies ranked the initial injuries according to the abbreviated injury scale 2005. Five studies reported the total risk of permanent medical impairment following RTIs which varied from 2% to 23% for car occupants and 2.8% to 46% for cyclists. Seven studies reported the risk of permanent medical impairment of the different body regions. Eleven studies stated the most common body region to develop permanent impairment, of which 6 studies demonstrated that injuries of the cervical spine and neck were at the highest risk of becoming permanent injured.@*CONCLUSION@#The finding of this review revealed the necessity of providing a globally validated method to evaluate permanent medical impairment following RTIs across the world. This would facilitate decision-making about traffic injuries and efficient management to reduce the financial and psychological burdens for individuals and communities.

Early postoperative small bowel obstruction after laparotomy for trauma: incidence and risk factors

PURPOSE: This study aimed to investigate the incidence and risk factors of early postoperative small bowel obstruction (EPSBO) after laparotomy for trauma patients. METHODS: From 2009 to 2016, consecutive patients who had undergone laparotomy for trauma were retrospectively evaluated. EPSBO was defined as the presence of signs and symptoms of obstruction between postoperative days 7 and 30, or obstruction occurring anytime within 30 days and lasting more 7 days. RESULTS: Among 297 patients who met the inclusion criteria, 72 (24.2%) developed EPSBO. The length of hospital stay was significantly longer in patients with EPSBO than in those without EPSBO (median [interquartile range], 34 [21–48] days 24 [14–38] days, P < 0.001). Multivariate logistic analysis identified male sex (adjusted odds ratio [AOR], 3.026; P = 0.008), intraoperative crystalloid (AOR, 1.130; P = 0.031), and Abbreviated Injury Scale (AIS) score for mesenteric injury (AOR, 1.397; P < 0.001) as independent risk factors for EPSBO. The incidence of adhesive small bowel adhesion after 30 days postoperatively did not significantly differ between the 2 groups (with EPSBO, 5.6% without EPSBO, 5.3%; P = 0.571). Most of the patients with EPSBO were recovered by conservative treatment (95.8%). CONCLUSION: After laparotomy for trauma patients, the incidence of EPSBO was 24.2% in our study. EPSBO was associated with a longer hospital stay. Male sex, use of intraoperative crystalloid, and AIS score for mesenteric injury were significant independent risk factors for EPSBO. Patients with these risk factors should be followed-up more carefully.

Risk Factors for Pneumonia in Ventilated Trauma Patients with Multiple Rib Fractures

BACKGROUND: Ventilator-associated pneumonia (VAP) is a common disease that may contribute to morbidity and mortality among trauma patients in the intensive care unit (ICU). This study evaluated the associations between trauma factors and the development of VAP in ventilated patients with multiple rib fractures. METHODS: We retrospectively and consecutively evaluated 101 patients with multiple rib fractures who were ventilated and managed at our hospital between January 2010 and December 2015, analyzing the associations between VAP and trauma factors in these patients. Trauma factors included sternal fracture, flail chest, diaphragm injury, traumatic aortic dissection, combined cardiac injury, pulmonary contusion, pneumothorax, hemothorax, hemopneumothorax, abbreviated injury scale score, thoracic trauma severity score, and injury severity score. RESULTS: Forty-six patients (45.5%) had at least 1 episode of VAP, 10 (21.7%) of whom died in the ICU. Of the 55 (54.5%) patients who did not have pneumonia, 9 (16.4%) died in the ICU. Using logistic regression analysis, we found that VAP was associated with severe lung contusion (odds ratio, 3.07; 95% confidence interval, 1.12 to 8.39; p=0.029). CONCLUSION: Severe pulmonary contusion (pulmonary lung contusion score 6–12) is an independent risk factor for VAP in ventilated trauma patients with multiple rib fractures.

Survival score scales of patients operated with spinal metastases: retrospective application in a Brazilian population / Escalas de prognóstico em pacientes operados com metástases vertebrais: aplicação retrospectiva em população brasileira

ABSTRACT Spinal cord epidural metastasis (SEM) is a common complication of systemic cancer. Predicting these patient’s survival is a key factor to select the proper treatment modality, but the three most used score scales to predict their survival (Tokuhashi revised score, Tomita score and Bauer modified score) were designed in single institutions and their reliability to predict correctly the patient’s survival were first tested only in those specific populations. This prognostication issue is addressed in this article, evaluating retrospectively the survival of 17 patients with SEM from a Brazilian general hospital with these score scales. Our results show that the actual survival of those patients were worse than the predicted of all three score scales, suggesting that differences between the different populations might have affected their reliability and alert that their usage as a major factor to select the most appropriate treatment have to be done with caution.

RESUMO Metástases vertebrais são uma complicação comum em pacientes com câncer sistêmico. Avaliar o prognóstico e a sobrevida desses pacientes é um fator de grande importância para escolher o tratamento mais adequado, porém as três escalas mais usadas atualmente para prever a sobrevida deles (Tokuhashi revisada, Tomita e Bauer modificada) foram desenhadas em instituições isoladas, e sua habilidade em estimar corretamente a sobrevida desses pacientes foram testadas primeiramente apenas nessas populações específicas. Essa questão de estimar o prognóstico é abordada nesse artigo, analisando retrospectivamente a sobrevida de 17 pacientes com metástase vertebral provenientes de um hospital geral no Brasil com essas escalas. Nossos resultados apontam que a sobrevida real desses pacientes foi menor que a prevista pelas três escalas, sugerindo que as diferenças entres as diferentes populações podem ter afetado a aplicabilidade delas. Assim, alertamos que o uso dessas escalas em populações diferentes das estudadas originalmente deve ser feito com cuidado.

Risk factors for mortality of severe trauma based on 3 years' data at a single Korean institution

PURPOSE: This study aimed to determine the mortality rate in patients with severe trauma and the risk factors for trauma mortality based on 3 years' data in a regional trauma center in Korea. METHODS: We reviewed the medical records of severe trauma patients admitted to Ajou University Hospital with an Injury Severity Score (ISS) > 15 between January 2010 and December 2012. Pearson chi-square tests and Student t-tests were conducted to examine the differences between the survived and deceased groups. To identify factors associated with mortality after severe trauma, multivariate logistic regression was performed. RESULTS: There were 915 (743 survived and 172 deceased) enrolled patients with overall mortality of 18.8%. Age, blunt trauma, systolic blood pressure (SBP) at admission, Glasgow Coma Scale (GCS) at admission, head or neck Abbreviated Injury Scale (AIS) score, and ISS were significantly different between the groups. Age by point increase (odds ratio [OR], 1.016; P = 0.001), SBP or = 4 (OR, 1.912; P = 0.003), and ISS by point increase (OR, 1.042; P < 0.001) were significant risk factors. CONCLUSION: In severe trauma patients, age, initial SBP, GCS score, head or neck AIS score, and ISS were associated with mortality.

Comparison of Injury Patterns and Severity between Younger and Older Rider in the Motorcycle Accident

PURPOSE: The mortality of motorcycle accidents in old age is very high in Korea compared with other countries. The aim of this study is to compare the differences in injury patterns and severity between younger and older riders in motorcycle accidents. METHODS: Cross sectional data from Konkuk University Chung-ju Hospital were used to evaluate patients who visited the emergency department as a result of a motorcycle accident from June 2012 to May 2014. We separated the patients into younger rider group from 16 to 64 and older rider group over 65 years of age. Injury sustained, the types of severe injuries and injury severity between two groups were compared using Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS). RESULTS: The younger and older rider group included 310 and 111 patients, respectively. Injuries in head, face, chest, and lumbar spine were higher in the older rider group (p<0.05). In the comparison of severe injury sustained over AIS 2, the older rider group had a four-fold odds increased rate of head injury (OR 3.718, 95% CI: 2.317-5.965, p<0.001) and a two-fold odds increased rate of chest injury (OR 2.306, 95% CI: 1.199-4.437, p=0.016) compared with the younger rider group. In addition, the older rider group had a nearly seven fold increased odds of severe injury over ISS 15 (OR 7.108, 95% CI: 3.579-14.119, p<0.001). CONCLUSION: In a motorcycle accident, the frequency of head, facial, chest, and lumbar injuries was higher in the older rider group. In addition, the older rider group had a higher injury severity, particularly a higher risk of head and chest injury.

Clinical Characteristics and Risk Factors in Severely Injured Elderly Trauma Presenting to Emergency Department

BACKGROUND: With increasing life expectancy, the number of injured elderly patients has been increasing. We evaluated the clinical characteristics of severely injured elderly patients who presented to the Emergency Department and identified risk factors associated with mortality. METHODS: Injured patients over 18 years of age who visited the Emergency Department with trauma team activation were investigated. We divided the patients into two groups according to age, an older adult group (> or =65 years) and a younger adult group ( or =3 of each body area, and mortality between the two groups. RESULTS: Among 177 severely injured patients, there were 138 younger adults (78%) and 39 older adults (22%). The average ISS of the older adults was higher than the younger adults (20.66 vs. 16.37). The incidences of severe injuries (ISS>15) in the younger adults and the older adults were 50.0% and 71.1%, respectively, and critical injuries (ISS>25) were 16.7% and 36.8%, respectively. Chest injuries and subdural hematoma occurred more often in the older adults. Mortality was higher in the older adults (28.2%) than in the younger adults (8.7%). CONCLUSION: The average ISS was higher in older adults than in younger adults, and older adults were significantly more likely to suffer severe trauma, especially chest injuries and subdural hematoma. The rate of mortality was greater for older adults (28.2%) than younger adults (8.7%).

Clinical Characteristics of Unstable Pelvic Bone Fractures Associated with Intra-abdominal Solid Organ Injury

PURPOSE: This study analyzed the characteristics of unstable pelvic bone fractures associated with intraabdominal solid organ injury. METHODS: Medical records were retrospectively collected from January 2000 to December 2010 for patients with unstable pelvic bone fractures. Unstable pelvic bone fracture was defined as lateral compression types II and III, antero-posterior compression types II and III, vertical shear and combined type by young classification. Subjects were divided into two groups, with (injured group) and without (non-injured group) intra-abdominal solid organ injury, to evaluate whether the characteristics of the fractured depended on the presence of associated solid organ injury. Data included demographics, mechanism of injury, initial hemodynamic status, laboratory results, revised trauma score (RTS), abbreviated injury scale (AIS), injury severity score (ISS), amount of transfusion, admission to the intensive care unit (ICU), and mortality. RESULTS: The subjects were 217 patients with a mean age of 44 years and included 134 male patients(61.8%). The injured group included 38 patients(16.9%). Traffic accidents were the most common mechanism of injury, and lateral compression was the most common type of fracture in all groups. The initial blood pressure was lower in the injured group, and the ISS was greater. The arterial pH was lower in the injured group, and shock within 24 hours after arrival at the emergency department was more frequent in the injured group. The amount of the transfused packed red blood cells within 24 hours was higher in the injured group than the non-injured group. Invasive treatment, including surgery and angiographic embolization, was more common in the injured group, and the stay in the ICU was longer in the injured group. CONCLUSION: A need exists to decide on a diagnostic and therapeutic plan regarding the possibility of intraabdominal solid organ injury for hemodynamically unstable patients with unstable pelvic bone fractures and multiple associated injuries.

Injury Severity and Patterns of Accompanying Injury in Spinal Fracture

PURPOSE: To examine the relationship between injury severity and patterns of associated injury in spinal fracture. MATERIALS AND METHODS: From March 2004 to March 2010, a retrospective study was conducted on 291 patients who had undergone surgeries due to spinal fractures. Spinal fractures were categorized as upper cervical, lower cervical, thoracic, thoracolumbar, and lumbar region, and the severity of fracture was measured using the Abbreviated Injury Scale and Injury Severity Score (ISS). We evaluated the correlation between the fracture site and the incidence and injury severity of the associated injury, and compared the neurologic damage according to the presence/absence of the associated injury. RESULTS: Spinal fracture occurred in the thoracic (43.5%) and lower cervical (30.0%) levels, and associated injury developed in 134 patients (47%). The area of associated injury was in the extremity (41.2%), thorax (25.5%), head, neck, and face (21.9%). Lower cervical fracture (34.5%) had a lower prevalence than thoracic (81%) and lumbar fracture (61%). The average ISS of the associated injury was 17.14 for the thoracic fracture, 12.30 for the lower cervical fracture, 8.7 for the thoracolumbar fracture and 5.69 for the lumbar fracture. Neurologic damage was highly frequent in the lower cervical fracture and included 54 patients (62.1%) and was less frequent in the upper cervical fracture, which included 7 patients (17.9%) (p=0.032). CONCLUSION: Although the associated injury was less frequent in the lower cervical spine among the spinal fractures that underwent surgical treatment, there was a high risk of neurologic damage in the case of associated injury; therefore, there is a need to pay special attention to patients that suffer damage in this area. In addition, since the degree of the associated injury in the thoracic and lower cervical fracture is significant, an appropriate management strategy for the associated injury must be considered.

Perfil lesional bucocervicofacial por agresión contra la mujer / Oral-cervicofacial injury profile due to violence against woman

Introducción: La violencia contra la mujer constituye un problema de salud a escala mundial. Objetivo: Determinar los niveles de gravedad lesional según calificadores de trauma en cirugía maxilofacial. Métodos: Se realizó un estudio observacional y descriptivo de 576 víctimas de lesiones bucocervicofaciales, atendidas en el Servicio de Urgencia de Cirugía Maxilofacial del Hospital Clinicoquirúrgico Provincial Saturnino Lora Torres de Santiago de Cuba desde septiembre del 2007 hasta diciembre del 2008, para lo cual se aplicaron 2 calificadores internacionales de severidad del trauma. Se empleó la prueba de Ji al cuadrado para muestras independientes, con un nivel de significación de p< 0,05. Resultados: Se hallaron 2 niveles de gravedad lesional: leve y moderado, tanto en las lesiones únicas como múltiples (en las primeras predominó el puñetazo y en la segunda el golpe con objetos contundentes); ambas categorías primaron en la región de tercio medio. Las puntuaciones promedios de las lesiones individuales en los tejidos blando y duro fueron de 1,13 y 1,45 puntos, respectivamente; en las múltiples, de 8,14 puntos en el tercio inferior y de 7,25 en más de una región anatómica afectada. Conclusiones: Las puntuaciones promedios fueron bajas en las lesiones orofaciales, tanto en las individuales como en las múltiples; por otra parte, los calificadores utilizados permitieron evaluarlas con mayor precisión, independientemente del mecanismo lesional que las produjo

Introduction: Violence against woman is a worldwide health problem. Objective: To determine levels of injury severity according to trauma qualifiers in maxillofacial surgery. Methods: An observational and descriptive study in 576 victims of oral-cervicofacial injuries attended at the Emergency Service of Maxillofacial Surgery from Saturnino Lora Torres Provincial Clinical-surgical Hospital in Santiago de Cuba was carried out from September, 2007 to December, 2008, in which case two international qualifiers of trauma severity were applied. The chi-square test was used for independent samples, with a significance level of p<0.05. Results: Two levels of injury severity were found, such as moderate and mild, both in single and multiple injuries (in the first ones, beats using the fist were relevant, while in the second ones, beats using blunt instruments were predominant). Both categories were of high prevalence in the middle third region. Mean scores of individual injuries in both soft and hard tissue were of 1.13 and of 1.45, respectively. Concerning multiple injuries, mean scores were of 8.14 in the lower third and of 7.25 in more than one of the anatomical region injured. Conclusions: Mean scores were low in orofacial injuries, in both individual and multiples. In contrast, the qualifiers used, allowed to assess them with more accuracy, independently from the injury mechanism that caused them

Clinical Outcomes and Risk Factors of Traumatic Pancreatic Injuries

PURPOSE: Even though traumatic pancreatic injuries occur in only 0.2% to 4% of all abdominal injuries, the morbidity and the mortality rates associated with pancreatic injuries remain high. The aim of this study was to evaluate the clinical outcomes of traumatic pancreatic injuries and to identify predictors of mortality and morbidity. METHODS: We retrospectively reviewed the medical records of 26 consecutive patients with a pancreatic injury who underwent a laparotomy from January 2000 to December 2010. The data collected included demographic data, the mechanism of injury, the initial vital signs, the grade of pancreatic injury, the injury severity score (ISS), the revised trauma score (RTS), the Glasgow Coma Scale (GCS), the number of abbreviated injury scales (AIS), the number of associated injuries, the initial laboratory findings, the amount of blood transfusion, the type of operation, the mortality, the morbidity, and others. RESULTS: The overall mortality rate in our series was 23.0%, and the morbidity rate was 76.9%. Twenty patients (76.9%) had associated injuries to either intra-abdominal organs or extra-abdominal organs. Two patients (7.7%) underwent external drainage, and 18 patients (69.3%) underwent a distal pancreatectomy. Pancreaticoduodenectomies were performed in 6 patients (23.0%). Three patients underwent a re-laparotomy due to anastomosis leakage or postoperative bleeding, and all patients died. The univariate analysis revealed 11 factors (amount of transfusion, AAST grade, re-laparotomy, associated duodenal injury, base excess, APACHE II score, type of operation, operation time, RTS, associated colon injury, GCS) to be significantly associated with mortality (p<0.05). CONCLUSION: Whenever a surgeon manages a patient with traumatic pancreatic injury, the surgeon needs to consider the predictive risk factors. And, if possible, the patient should undergo a proper and meticulous, less invasive surgical procedure.

Fracturas de pilón tibial: estado actual de pacientes que ingresaron al Instituto Autónomo Hospital Universitario de Los Andes entre 1998-2007 aplicando la AOFAS: estudio observacional analítico prospectivo no concurrente / Tibial pilon fractures: currents status of patients admitted to the Instituto Autónomo Hospital Universitario de Los Andes between 1998-2007 using the AOFAS: prospective observacional study non-concurrent

Las fracturas de tibia distal han sido consideradas de difícil manejo debido a los resultados desalentadores descritos hasta el año de 1963 situación que comienza a cambiar a mediados de 1968 cuando se promulgan los principios de ORIF de la AO, sin embargo, actualmente sigue constituyendo un verdadero reto para el cirujano traumatólogo. En el presente estudio prospectivo no concurrente se evaluarán los pacientes adultos (mayores de 16 años de edad) que ingresaron al servicio de Ortopedia y Traumatología del Instituto Autónomo Hospital Universitario de Los Andes (IAHULA) entre 1998 y 2007 con fracturas de tibia distal (pilon tibial), constituyendo en total una población de 80 pacientes de la cual se toma una muestra de 40 pacientes. Para efectos de este estudio obtuvimos para las fracturas tipo A según la AO/ASIF un total de 33,3 por ciento de excelentes resultados, 33,3 por ciento de regulares resultados y 33,3 por ciento de malos resultados. Para las fracturas tipo B 71 por ciento de excelentes resultados, 15 por ciento de regulares resultados y 14 por ciento de malos resultados; mientras que para las fracturas de tipo C fue un 27 por ciento de excelentes resultados, 27 por ciento de regulares resultados y 46 por ciento de malos resultados, todos evaluados según la escala de evaluación de la AOFAS. A la luz de los estudios consultados, resulta evidente establecer como aspectos pronóstico determinantes el estado de las partes blandas la afectación metafisiaria y/o articular, así como la asociación a una lesión de peroné.

Distal tibia fracture have been considered difficult to use because of the disappointing results described until the years 1963 which begins to change in mid-1968 when it enacted the principles of ORIF of AO, however, currently still be a real challenge to the trauma surgeon. This prospective study will assess the concurrent non-adult patients (older than 16 years of age) who entered the service of Orthopedics and Traumatology Institute of the University Hospital of Los Andes (IAHULA) between 1998 and 2007 with fractures distal tibia (tibia pylon), constituting a total population of 80 patients of which took a sample of 40 patients. For purposes of this study, we obtained for type A fractures according to AO/ASIF a total of 33,3 percent of excellent results, 33,3 percent of regular results, and 33,3 percent poor results. For fractures type B 71 percent of excellent results, 15 percent regular results, and 14 of poor results, whereas for type C fractures was 27 percent excellent results, 27 percent of regular results, and 46 percent of poor results all assessed according to the scale of assessement of the AOFAS. In light of the studies consulted, as is evident establish prognostic determinants respects the status of soft tissue involvement, metaphyseal and/or joints, as well as the association of a fibula injury.

Analysis of the Factors that Influence the Severity of Injury of Pedestrian Traffic Accident Patients in an Emergency Department

PURPOSE: Pedestrian traffic accident (TA) deaths account for 40% of Korea's annual TA fatalities. With that in mind, we reviewed the cases of traumatic pedestrian TA patients admitted to emergency medical centers in Korea. We analysed factors affecting the severity of injury in order to investigate risk factors for subsequent traumatic threats. METHODS: Prospective methods were applied using a prepared trauma recording format. Trauma records included patient factors (age, gender, occupation, underlying disease), accident factors (time of accident, weather conditions, transportation time, vehicle type causing the accident, influence of alcoholic on both drivers and victims, accident location), and other factors (means of initial hospital admittance transportation). We reviewed medical records to obtain data for vital signs, Glasgow coma scale (GCS), abbreviated injury scale (AIS), injury severity score (ISS), and trauma and injury severity score (TRISS). We divided subjects into 3 groups according to their ISS scores: mild (1-8 points), moderate (9-15 points), severe (>==16 points). These groups were compared with each other regarding degree of severity? RESULTS: We analyzed data for 23,392 traumatized patients that presented at an EMC. Of the 23,392, 252 (3.1%) were pedestrian TA patients. Among this pedestrian cohort, males 156 patients (male 61.9% and female 38.1%; p=0.332). Mean age was 43.1 (+/-19.9). Severity was greater in those over 40 years of age compared those under 40 (p=0.000). Farmer's had the greatest severity than patients in other occupations (p=0.004). Those with an underlying disease showed a higher degree of severity (p=0.028). The most common accident site was city roads (85.7%) but the degree of severity at such sites did not was not significantly greater (p=0.052). Sports utility vehicle (SUV) had the highest rate of accident severity (p=0.004). Cases involving drunken drivers had victims with higher severity (p=0.005). CONCLUSION: Factors that increase the rate of fatalities pedestrian TAs are: older age, underlying illness, working in the agricultural sector, driving an SUV, the patient being in a drunken state.

Clinical Characteristics of Intraperitoneal and Retroperitoneal Solid Organ Injuries after Trauma

PURPOSE: The aim of this study was to analyze the characteristics and prognosis of intraperitoneal and retroperitoneal solid organ injuries after trauma. METHODS: We analyzed computed tomography (CT) data for 232 patients who had injury to solid abdominal organs between January 2002 and June 2009. The patients who had solid organ injury on CT were categorized into intraperitoneal, retroperitoneal and intra/retroperitoneal injury groups. Medical records were reviewed retrospectively, and data regarding the sex and age of patients, mechanism of injury, initial hemodynamic status, Revised Trauma Score (RTS), Abbreviated Injury Scale (AIS), Injury Severity Score (ISS), amount of transfusion, admission rate to intensive care unit (ICU), and mortality were collected and analyzed. Injury severity of solid organs was classified according to the American Association for the Surgery of Trauma (AAST) grading system. RESULTS: The intraperitoneal injury group had 131 patients, the retroperitoneal injury group 49 patients, and the intra/retroperitoneal injury group 52 patients. The intra/retroperitoneal injury group exhibited low blood pressure, a large number of packed red blood cells that were transfused, and high ISS and abdominal AIS. They tended to stay longer in the ICU and showed a higher mortality. Conservative management was the most common therapeutic modality for all 3 groups. CONCLUSION: The intra/retroperitoneal injury group showed higher fall for the mecahnism of injury, a lower initial blood pressure and a larger number of packed red blood cells that were transfused compared with the other groups. Therefore, physicians should rapidly identify those with a poor prognosis at initial presentation and make a decision quickly when they are caring for intra/retroperitoneal injury patients.

OBJETIVO: Avaliar as características das vítimas de queda da própria altura, principalmente a respeito da frequência de lesões graves, seu diagnóstico e tratamento. MÉTODOS: Estudo retrospectivo dos protocolos de trauma (coletados prospectivamente) de 10/06/2008 a 10/03/2009, incluindo as vítimas de trauma fechado com idade igual ou superior a 13 anos admitidas na sala de emergência. Consideraremos como "graves" as lesões com escore de AIS (Abbreviated Injury Scale) maior ou igual a três. As variáveis foram comparadas entre o grupo de vítimas de quedas da própria altura (Grupo I) e as demais vítimas de trauma fechado (Grupo II). Empregamos os testes T de Student, Qui quadrado e Fisher para a comparação entre os grupos, considerando o valor de p<0,05 como significante. RESULTADOS: Foram analisados 1993 casos de trauma fechado, sendo que 305 (15 percent) foram vítimas de quedas da própria altura (Grupo I). A média etária nas vítimas de quedas da própria altura foi 52,2 ± 20,9 anos, sendo 64,8 percent do sexo masculino. Noventa e oito (32,1 percent) tinham idade acima de 60 anos. No grupo I, as lesões em segmento cefálico foram as mais encontradas (62,2 percent), seguidas das lesões em extremidades (22,3 percent), torácicas (1,3 percent) e abdominais (0,7 percent). As lesões graves (AIS>3) foram mais frequentemente observadas em segmento cefálico (8,9 percent), seguidas pelas lesões em extremidades (4,9 percent). A craniotomia foi necessária em 2,3 percent das vítimas de quedas de própria altura. Observamos que, em comparação às vítimas de outros mecanismos de trauma fechado, as vítimas de quedas da própria altura apresentavam, significantemente (p<0,05), maior média etária, maior média de pressão arterial sistólica à admissão e maior média de AIS em segmento cefálico bem como menor média de ISS, de AIS em tórax, de AIS em abdome e AIS em extremidades. CONCLUSÃO: A valorização do mecanismo de trauma nas vítimas de quedas da própria altura é de extrema importância, visto a possibilidade de haver lesões graves e clinicamente ocultas, principalmente em segmento cefálico.

OBJECTIVE: Assess characteristics of trauma patients who sustained falls from their own height, more specifically focusing on presence of severe injuries, diagnosis and treatment. METHODS: Retrospective study including all adult blunt trauma patients admitted in the emergency room in a period of 9 months. Lesions with AIS (Abbreviated Injury Scale)>3 were considered "severe". Variables were compared between victims of fall from their own height (group I) and other blunt trauma mechanisms (group II). Student's t, chi square and Fisher exact tests were used for statistical analysis, considering p<0.05 as significant. RESULTS: Of the 1993 trauma patients included, 305 (15 percent) were victims of falls from their own height. In group I, mean age was 52.2 ± 20.8 years and 64.8 percent were male. Injuries in the head segment were the most frequently observed (62.2 percent), followed by injuries in the extremities (22.3 percent), thorax (1.3 percent) and abdomen (0.7 percent). Severe injuries (AIS>3) were more frequent in the head (8.9 percent), followed by extremities (4,9 percent). In group I, craniotomies were needed in 2.3 percent. By comparing groups, we observed that victims of falls from their own height had significantly higher mean age, higher mean systolic blood pressure, and higher head AIS mean, as well as lower ISS mean, thorax AIS mean, abdomen AIS mean and extremities AIS mean. CONCLUSION: Importance of the trauma mechanism in victims of falls from own height should be emphasized due to a considerable possibility of occult severe injuries, mainly in the cephalic segment.

Characteristics of Stable Pelvic Bone Fractures with Intra-abdominal Solid Organ Injury

PURPOSE: This study analyzed the characteristics of stable pelvic bone fractures with intra-abdominal solid organ injury. METHODS: Medical records were retrospectively reviewed from January 2000 to December 2009 of patients with stable pelvic bone fractures. A stable pelvic bone fracture according to Young's classification is defined as a lateral compression type I and antero-posterior compression type I. Subjects were divided into two groups, one with (injured group) and one without (non-injured group) intra-abdominal solid organ injury, to evaluate the dependences of the characteristics on the presence of an intra-abdominal solid organ injury. Data including demographics, mechanism of injury, initial hemodynamic status, laboratory results, Revised Trauma Score (RTS), Abbreviated Injury Scale (AIS), Injury Severity Score (ISS), amount of transfusion, admission to intensive care unit (ICU), and mortality were analyzed. RESULTS: The subjects were 128 patients with a mean age of 42 years old, of whom were 67 male patients (52.3%). The injured group had 21 patients(16.4%), and the most frequent injured solid organ was the liver. Traffic accident was the most common mechanism of injury and lateral compression was the most common type of fracture in all groups. Initial systolic blood pressure was lower in the injured group, and the ISS was greater in the injured group. Arterial pH was lower in the injured group, and shock within 24 hours after arrival at the emergency department was more frequent in the injured group. Transfused packed red blood cells within 24 hours were 8 patients(38.1%) in the injured group and 11 patients(10.3%) in the non-injured group. Conservative treatment was the most common therapeutic modality in all groups. Stay in the ICU was longer in the injured group, and three mortalities occurred. CONCLUSION: There is a need to decide on a diagnostic and therapeutic plan regarding the possibility of intra-abdominal solid organ injury for hemodynamically unstable patients with stable pelvic bone fractures and for patients with stable pelvic bone fractures along with multiple associated injuries.

Analysis of the Risk Factors Influencing the Severity of Injury in Pediatric Multiple Trauma Patients

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(+/-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+/-6.42) and the most serious degree (P=0.004). The ISS level of injury (8.40+/-6.64) for patients moved from a secondary hospital was higher than that (6.49+/-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+/-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+/-8.56 and 11.23+/-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.

Multiple Intraabdominal Solid Organ Injuries after Blunt Trauma

PURPOSE: This study evaluated the characteristics and the prognosis of multiple intraabdominal solid organ injuries, including those to the liver, spleen, and kidney, after blunt trauma. METHODS: From January 2001 to March 2009, 39 patients with multiple intraabdominal solid organ injuries, which had been confirmed by contrast-enhanced computed tomography after blunt trauma, were included in this retrospective study. The injury severity score (ISS), abbreviated injury scale (AIS), revised trauma score (RTS), American Association for the Surgery of Trauma (AAST) injury grade of solid organs, initial hemodynamic status, blood gas analysis, blood transfusion, and the mortality were the main outcome measurements. RESULTS: Injured groups were classified into liver/kidney (n=17), liver/spleen (n=4), spleen/kidney (n=13), and liver/kidney/spleen (n=5) groups. Patients were older in the liver/kidney group than in the liver/kidney/spleen group (43 vs 18 years, p=0.023). The initial systolic blood pressures tended to be lower in the liver/kidney group than in the other groups (84 vs 105, 112, and 114 mmHg, p=0.087). The amounts of 24-hour packed RBC transfusion were 32 units in the liver/kidney group and 4 units in the liver/kidney/spleen group, but the difference was not statistically significant. Differences were found in neither the RTS, ISS, and AIS for head, chest, abdominal, and pelvic injuries nor the AAST injury grade for solid organ, but injuries to the chest were more severe in the liver/spleen group than in the spleen/kidney group (AIS 4.0 vs 2.8, p=0.028). Conservative treatment was the most frequent applied treatment in all groups. There were 6 mortalities : 3 due to hypovolemia, 2 to sepsis, and 1 to brain injury. Mortalities occurred only in the liver/kidney group. CONCLUSION: Patients who had intraabdominal solid organ injuries of the liver and the kidney simultaneously, tended to be transfused more at an early time after trauma, to have lower initial systolic blood pressures, and to have a higher mortality.
