RESUMO
INTRODUCTION: measuring the severity of traumatic injuries is crucial for predicting clinical outcomes. Whereas the Injury Severity Score (ISS) has limitations in assigning scores to injuries at the same site, the New Injury Severity Score (NISS) corrects for this problem by taking into account the three most severe injuries regardless of the region of the body. This study seeks to comprehend the clinical and epidemiological profile of trauma patients while comparing the effectiveness of scales for predicting mortality. METHODS: a descriptive, observational and retrospective study using records of patients who underwent thoracotomy at the Hospital das Clínicas of the Federal University of Triângulo Mineiro between 2000 and 2019. Demographic data, mechanisms of injury, affected organs, length of stay and mortality were analyzed. Injury severity was assessed using the ISS and NISS, and statistical analyses were conducted using MedCalc and SigmaPlot. RESULTS: 101 patients were assessed, on average 29.6 years old, 86.13% of whom were men. The average duration of hospitalization was 10.9 days and the mortality rate was 28.7%. The ROC curve analysis revealed a sensitivity of 68.97%, specificity of 80.56% and area under the curve of 0.837 for the ISS, and 58.62%, 94.44% and 0.855 for the NISS, respectively. The Youden index was 0.49 for the ISS and 0.53 for the NISS. CONCLUSION: the study demonstrated comparable efficacy of NISS and ISS in predicting mortality. These findings hold significance in the hospital setting. Professionals must be familiar with these scales to utilize them competently for each patient.

Importance: Short- and long-term functional impairment after pediatric injury may be more sensitive for measuring quality of care compared with mortality alone. The characteristics of injured children and adolescents who are at the highest risk for functional impairment are unknown. Objective: To evaluate categories of injuries associated with higher prevalence of impaired functional status at hospital discharge among children and adolescents and to estimate the number of those with injuries in these categories who received treatment at pediatric trauma centers. Design, Setting, and Participants: This prospective cohort study (Assessment of Functional Outcomes and Health-Related Quality of Life After Pediatric Trauma) included children and adolescents younger than 15 years who were hospitalized with at least 1 serious injury at 1 of 7 level 1 pediatric trauma centers from March 2018 to February 2020. Exposure: At least 1 serious injury (Abbreviated Injury Scale score, ≥3 [scores range from 1 to 6, with higher scores indicating more severe injury]) classified into 9 categories based on the body region injured and the presence of a severe traumatic brain injury (Glasgow Coma Scale score <9 or Glasgow Coma Scale motor score <5). Main Outcomes and Measures: New domain morbidity defined as a 2 points or more change in any of 6 domains (mental status, sensory, communication, motor function, feeding, and respiratory) measured using the Functional Status Scale (FSS) (scores range from 1 [normal] to 5 [very severe dysfunction] for each domain) in each injury category at hospital discharge. The estimated prevalence of impairment associated with each injury category was assessed in the population of seriously injured children and adolescents treated at participating sites. Results: This study included a sample of 427 injured children and adolescents (271 [63.5%] male; median age, 7.2 years [interquartile range, 2.5-11.7 years]), 74 (17.3%) of whom had new FSS domain morbidity at discharge. The proportion of new FSS domain morbidity was highest among those with multiple injured body regions and severe head injury (20 of 24 [83.3%]) and lowest among those with an isolated head injury of mild or moderate severity (1 of 84 [1.2%]). After adjusting for oversampling of specific injuries in the study sample, 749 of 5195 seriously injured children and adolescents (14.4%) were estimated to have functional impairment at hospital discharge. Children and adolescents with extremity injuries (302 of 749 [40.3%]) and those with severe traumatic brain injuries (258 of 749 [34.4%]) comprised the largest proportions of those estimated to have impairment at discharge. Conclusions and Relevance: In this cohort study, most injured children and adolescents returned to baseline functional status by hospital discharge. These findings suggest that functional status assessments can be limited to cohorts of injured children and adolescents at the highest risk for impairment.

INTRODUCTION: Extensive research relying on Injury Severity Scores (ISS) reports a mortality benefit from routine non-selective thoracic CTs (an integral part of pan-computed tomography (pan-CT)s). Recent research suggests this mortality benefit may be artifact. We hypothesized that the use of pan-CTs inflates ISS categorization in patients, artificially affecting admission rates and apparent mortality benefit. METHODS: Eight hundred and eleven patients were identified with an ISS >15 with significant findings in the chest area. Patient charts were reviewed and scores were adjusted to exclude only occult injuries that did not affect treatment plan. Pearson chi-square tests and multivariable logistic regression were used to compare adjusted cases vs non-adjusted cases. RESULTS: After adjusting for inflation, 388 (47.8%) patients remained in the same ISS category, 378 (46.6%) were reclassified into 1 lower ISS category, and 45 (5.6%) patients were reclassified into 2 lower ISS categories. Patients reclassified by 1 category had a lower rate of mortality (P < 0.001), lower median total hospital LOS (P < .001), ICU days (P < .001), and ventilator days (P = 0.008), compared to those that remained in the same ISS category. CONCLUSION: Injury Severity Score inflation artificially increases survival rate, perpetuating the increased use of pan-CTs. This artifact has been propagated by outdated mortality prediction calculation methods. Thus, prospective evaluations of algorithms for more selective CT scanning are warranted.

Introduction The AOSpine Thoracolumbar Spine Injury Classification (AOSTSIC) system has been proposed to better characterize injury morphologies and improve the classification of thoracolumbar (TL) spine trauma. However, the indications for surgical treatment according to the AOSTSIC system are still debated. Additionally, the proposed Thoracolumbar AOSpine Injury Score (AOSIS) is quite complex, which may preclude its use in daily practice. The objective of this reviewis to discuss the AOSTSIC systemand its indications for initial nonoperative versus surgical management of acute TL spine trauma. Methods We analyzed the literature for each injury type (and subtype, when pertinent) according to the AOSTSIC system as well as their potential treatment options. Results Patients with AOSTSIC subtypes A0, A1, and A2 are neurologically intact in the vast majority of the cases and initially managed nonoperatively. The treatment of A3- and A4-subtype injuries (burst fractures) in neurologically-intact patients is still debated with great controversy, with initially nonoperative management being considered an option in select patients. Surgery is recommended when there are neurological deficits or failure of nonoperativemanagement,with the role of magnetic resonance findings in the Posterior Ligamentous Complex (PLC) evaluation still being considered controversial. Injuries classified as type B1 in neurologically-intact patients may be treated, initially, with nonoperative management, provided that there are no ligamentous injury and non-displacing fragments. Due to severe ligamentous injury, type-B and type-C injuries should be considered as unstable injuries that must be surgically treated, regardless of the neurological status of the patient. Conclusions Until further evidence, we provided an easy algorithm-based guide on the spinal trauma literature to help surgeons in the decision-making process for the treatment of TL spine injuries classified according to the new AOSTSIC system.

Prognostic determinants in thoracic trauma are of major public health interest. We intended to describe patterns of thoracic trauma, demographic factors, clinical course, and predictors of outcome in selected tertiary care hospitals in Sri Lanka. A multicentre prospective cohort study was conducted in five leading teaching hospitals from June to September 2017. Patients with thoracic trauma were followed up during the hospital stay. A logistic regression analysis was conducted using in-hospital morbidity as the dichotomous outcome variable. One hundred seventy-one patients were included in the study yielding 1450 (median = 8.5) person-days of observation. Of them, 71.9% (n = 123) were males. The mean age was 45.8 ± 17.9 years. Majority (39.2%, n = 67) were recruited from the National Hospital of Sri Lanka. Automobile accidents were the commonest (62.6%, n = 107), followed by falls (26.9%, n = 46), assaults (8.8%, n = 15), and animal attacks (1.8%, n = 3). The ratio of blunt to penetrating trauma was 5.6 : 1. Injury patterns were rib fractures (80.7%, n = 138), haemothorax (44.4%, n = 76), pneumothorax (44.4%, n = 76), lung contusion (22.8%, n = 39), flail segment (15.8%, n = 27), tracheobronchial trauma (7.0%, n = 12), diaphragmatic injury (2.3%, n = 4), vascular injury (2.3%, n = 4), cardiac contusions (1.1%, n = 2), and oesophageal injury (0.6%, n = 1). Ninety nine (57.9%) had extrathoracic injuries. Majority (63.2%, n = 108) underwent operative management including intercostal tube insertion (60.8%, n = 104), wound exploration (6.4%, n = 11), thoracotomy (4.1%, n = 7), rib reconstruction (4.1%, n = 7), and video-assisted thoracoscopic surgery (2.9%, n = 5). Pneumonia (10.5%, n = 8), bronchopleural fistulae (2.3%, n = 4), tracheaoesophageal fistulae (1.8%, n = 3), empyema (1.2%, n = 2), and myocardial infarction (1.2%, n = 2) were the commonest postoperative complications. The mean hospital stay was 15.6 ± 18.0 days. The in-hospital mortality was 11 (6.4%). The binary logistic regression analysis with five predictors (age, gender, mechanism of injury (automobile/fall/assault), type of trauma (blunt/penetrating), and the presence of extrathoracic injuries) was statistically significant to predict in-hospital morbidity (X 2 (6, n = 168) = 13.1; p=0.041), explaining between 7.5% (Cox and Snell R 2) and 14.5% (Nagelkerke R 2) of variance. The automobile accidents (OR: 2.3, 95% CI = 0.2-26.2) and being males (OR: 2.3, 95% CI = 0.6-9.0) were the strongest predictors of morbidity.

Blunt chest wall injuries are a significant cause of mortality and morbidity in trauma patients. Accurate identification and description of chest wall injuries by the radiologist can aid in guiding proper patient management. The American Association for the Surgery of Trauma (AAST) has devised a classification system based on severity. This article describes the features of each injury grade according to the AAST injury scale and discusses the implications for management. Additionally, common mechanisms of blunt chest trauma and multimodal imaging techniques are discussed.

OBJECTIVE: to evaluate epidemiology, anatomical characteristics, management, and prognosis of critical patients with sternum fractures. METHODS: retrospective analysis of patients admitted to intensive care unit (ICU) of a Level III trauma center in Sao Paulo, Brazil. RESULTS: 1552 trauma patients were admitted from January 2012 to April 2016. A total of 439 patients had thoracic trauma and among these, 13 patients had sternum fracture, making up 0.9% of all trauma admissions and 3% of all thoracic trauma cases. Three of these 13 patients had unstable chest, two underwent surgical management for fracture fixation, and three died (mortality was of 29%). In one of the deaths, sternum fracture was assessed as the main contributor to the outcome. CONCLUSION: sternum fracture was diagnosed in 0.9% of critical trauma patients in a specialized ICU. Only 15% of patients required specific surgical management in the acute phase. In most cases, mortality was due to other injuries.
OBJETIVO: avaliar epidemiologia, características anatômicas, manejo e prognóstico de pacientes críticos com fraturas de esterno. MÉTODOS: análise retrospectiva de pacientes internados em unidade de terapia intensiva (UTI) de emergências cirúrgicas e trauma de um centro de trauma Tipo III em São Paulo, Brasil. RESULTADOS: foram admitidos 1552 pacientes traumatizados no período de janeiro de 2012 a abril de 2016. Desses, 439 apresentavam trauma torácico e 13 apresentavam fratura de esterno, configurando 0,9% das admissões de trauma e 3% dos traumas torácicos. Desses pacientes, três apresentavam tórax instável e dois foram submetidos à conduta cirúrgica para fixação da fratura. A mortalidade de pacientes com fratura de esterno foi de 29% (três pacientes). Em um dos óbitos pôde-se atribuir a fratura do esterno como contribuinte principal para o desfecho. CONCLUSÃO: a fratura de esterno foi diagnosticada em 0,9% dos pacientes críticos vítimas de trauma em UTI especializada. Somente 15% dos pacientes necessitaram de conduta cirúrgica específica na fase aguda e a mortalidade foi decorrente das outras lesões na maior parte dos casos.

Slipping rib syndrome is an often unrecognized and underdiagnosed condition caused by the increased mobility of the anterior ends of the costal cartilages of the false ribs. Patients usually present with severe intermittent abdominal pain that is exacerbated by various physical movements. Diagnosis of slipping rib syndrome is mainly clinical and can be confirmed by a physical examination technique termed the "Hooking Maneuver." Treatment includes conservative therapy, intercostal nerve block and surgical operation. Hence, the management and care plan of each patient must be individualized as per the presenting symptoms and medical history. Early recognition and prompt intervention necessitate that physicians be more aware of the symptomatology and prognosis of this condition. This study presents a rare case of a patient with slipping rib syndrome and offers medical insight to the clinical diagnosis and therapeutic modalities of this condition, in light of the current existing literature.

OBJECTIVE: to determine the frequency of fatal cardiac trauma in the city of Manaus, Brazil, between November 2015 and October 2016, and to clarify the mechanisms of trauma and death, previous hospital treatment, as well as the injuries associated with cardiac trauma. METHODS: retrospective, observational, and cross-sectional study, which reviewed the necropsy reports of individuals whose cause of death was cardiac injury. RESULTS: the cardiac trauma rate was of 5.98% (138 cases) out of 2,306 necropsies performed in the study period by Instituto Médico Legal (IML) de Manaus (IML is a Brazilian institute responsible for necropsies and cadaveric reports). Males accounted for 92% of the cases. The median age was 27 years (14-83). Gunshot wounds (GSW) was the trauma mechanism in 62.3% and stab wound (SW) in 29.7%. Exsanguination was responsible for most of the deaths and cardiac tamponade was present in second place. On-site death occurred in 86.2% of the cases. The ventricles were the most common site of cardiac injury. Hemothorax was identified in 90.6% of the individuals. Only 23 patients (16.7%) were taken to the hospital (Emergency Room), but six (26.2%) were submitted only to chest drainage, not to thoracotomy. The lung was unilaterally affected in 57% of the cases and bilaterally in 43%. CONCLUSION: fatal cardiac trauma represented an index of 5.98% in the city of Manaus. Most patients die at the scene of the trauma, usually due to exsanguination caused by gunshot wound. About a quarter of patients who reached the hospital and died were not diagnosed with cardiac trauma in time.

RESULTADOS: o índice de trauma cardíaco foi de 5,98% (138 casos) dentre 2306 necropsias realizadas no período do estudo. Homens foram afetados em 92%. A mediana de idade foi de 27 anos (14 a 83). A arma de fogo foi o mecanismo de trauma em 62,3% e a arma branca em 29,7%. A exsanguinação foi responsável pela maioria das mortes e o tamponamento cardíaco esteve presente em segundo lugar. Óbito no local ocorreu em 86,2%. Os ventrículos foram as câmaras mais lesionadas. O hemotórax foi descrito em 90,6%. Apenas 23 (16,7%) doentes foram removidos até o pronto socorro, porém seis deles (26,2%) não foram submetidos à toracotomia, apenas à drenagem de tórax. O pulmão foi acometido em 57% unilateralmente e 43% bilateralmente. CONCLUSÃO: o trauma cardíaco fatal representou um índice de 5,98% na cidade de Manaus. A maioria dos doentes morre na cena do trauma, geralmente devido à exsanguinação causada por ferimento de arma de fogo. Cerca de um quarto dos pacientes que chegaram ao pronto socorro e morreram, não foram diagnosticados com trauma cardíaco em tempo hábil.

BACKGROUND: Trauma is the leading cause of death in young patients and thoracic trauma (TT) is responsible for 25-35% of trauma deaths. AIM: To describe and compare features, trauma severity indexes and morbidity of patients admitted for TT in the past three decades. MATERIAL AND METHODS: Review of a TT database, operative notes and medical records of patients. These were separated by decade of admission (1981-1990, 1991-2000, 2001-2010). TT characteristics were compared. Injury Severity Score (ISS), Revised Trauma Score (RTS-T) and Trauma Injury Severity Score (TRISS) were calculated. RESULTS: A total of 3,068 TT were reviewed. In the 1981-1990 period, 604 cases of TT were registered (19.7%), in the 1991-2000 period, 1,070 cases (34.9%) and in the 2001-2010 period, 1,394 cases (45.4%) (p < 0.05). The ages of patients in each of these periods were 34.9 ± 15.5, 33.9 ± 16.2 and 35.7 ± 18.2 years respectively (p < 0.05). The proportion of patients aged 65 years or more were 6.6, 7.7 and 10.1% respectively, the proportion of females was 6.1, 9.4 and 12.0%, respectively. The causing agents per decade were knife wounds in 51.5, 61.1 and 60.0% of cases respectively, firearms in 2.5, 3.3 and 5.0% of cases respectively, multiple trauma in 13.9, 14.5 and 9.0% respectively and morbidity in 18.7, 19.7 and 11.7%, respectively. The ISS per decade was 11.9 ± 6.5, 12.9 ± 6.9 and 10.4 ± 6.8 respectively. No significant difference were found in mortality (1.5, 3.0, 2.0% respectively) or TRISS score (2.7, 3.2 and 3.8% respectively). CONCLUSIONS: An increase in the number of hospital admission for TT has occurred in the last three decades, with an increase in the proportion of admissions of subjects aged 65 years or more, females and with firearm injuries.

Males accounted for 92% of the cases. The median age was 27 years (14-83). Gunshot wounds (GSW) was the trauma mechanism in 62.3% and stab wound (SW) in 29.7%. Exsanguination was responsible for most of the deaths and cardiac tamponade was present in second place. On-site death occurred in 86.2% of the cases. The ventricles were the most common site of cardiac injury. Hemothorax was identified in 90.6% of the individuals. Only 23 patients (16.7%) were taken to the hospital (Emergency Room), but six (26.2%) were submitted only to chest drainage, not to thoracotomy. The lung was unilaterally affected in 57% of the cases and bilaterally in 43%. Conclusion: fatal cardiac trauma represented an index of 5.98% in the city of Manaus. Most patients die at the scene of the trauma, usually due to exsanguination caused by gunshot wound. About a quarter of patients who reached the hospital and died were not diagnosed with cardiac trauma in time.

BACKGROUND: Despite increases in imaging guidelines for other body-regions during initial trauma assessment and the demonstrated utility of chest radiographs (CXR), guidelines for use of thoracic computed-tomography (TCT) are lacking. We hypothesized that TCT utilization had not decreased relative to other protocolized CTs, and mechanism and CXR could together predict significant injury independent of TCT. METHODS: We performed a retrospective review of blunt trauma patients ≤18 y.o. (2007-2015) at two level-1 trauma centers who received chest imaging. Baseline characteristics and incidences of body region-specific CT were compared. Injury mechanism, intrathoracic pathology, and interventions among other data were examined (significance: p<0.05). RESULTS: Although other body-region CT incidence decreased (p<0.05), TCT incidence did not change (p=0.65). Of the 2951 patients, 567 had both CXR and TCT, 933 received TCT-only, and 1451 had CXR-only. TCT altered management in 17 patients: 2 operations, 1 stent-placement, 1 medical management, 9 thoracostomy tube placements, and 4 negative diagnostic workups. All clinically significant changes were predicted by vehicle-related mechanism and abnormal CXR findings. CONCLUSIONS: TCT utilization has not decreased over time. All meaningful interventions were predicted by CXR and mechanism of injury. We propose a rule, for prospective validation, reserving TCT for patients with abnormal CXR findings and severe vehicle-related trauma. LEVEL OF EVIDENCE: Diagnostic study, Level III.

PURPOSE: Traumatic aortic injury (TAI) is a rare but life-threatening type of injury. We investigate whether the anatomy of the aortic arch influences the severity of aortic injury. METHODS: This is a retrospective study of twenty-two cases treated with TEVAR for TAI in our department from 2009 to 2014. Aortic injury was assessed in accordance with the recommendations of the Society of Vascular Surgery. We measured the aortic arch angle and the aortic arch index, based on the initial angio-CT scan, in each of the analyzed cases. RESULTS: The mean aortic arch index and mean aortic arch angle were 6.8 cm and 58.3°, respectively, in the type I injury group; 4.4 cm and 45.9° in the type III group; 3.3 cm and 37° in the type IV group. There were substantial differences in both the aortic arch index and the aortic arch angle of the type III and IV groups. A multivariate analysis confirmed that the aortic arch angle was significantly associated with the occurrence of type III damage (OR 1.5; 95% CI 1.03-2.2). CONCLUSIONS: The severity of TAI is influenced by the sharpness of the aortic arch. There is an inverse relationship between the severity of aortic injury and the aortic arch index.

Thoracic trauma is the second cause of death for trauma in children. It is caused by mechanisms of high energy, principally motor vehicle collision. Multisystemic injuries are frequent. Management involves knowledge and understanding the anatomy, physiologyand the mechanism of the injuries, their change at different ages and the difference from adults. Pediatric chest trauma is caused mainly by contusion and there is increasing penetrating trauma in adolescents. The most common injuries are pulmonary contusion, hemothorax and pneumothorax with rib fractures. Airway, great vessels and heart injuries are rare but very serious. Most of thoracic injuries are solved by respiratory and hemodynamic support measurements, and tube thoracostomy. It is vital to recognize, in initial evaluation, those potentially lethal injuries, which give no time for radiological evaluation.
El traumatismo torácico es la segunda causa de muerte por trauma en niños. Es causado por mecanismos de alta energía, principalmente accidentes de tránsito, siendo frecuentes las lesiones multisistémicas, lo que aumenta su gravedad. Un manejo adecuado requiere conocer y entender como la anatomía, fisiología y los patrones de las lesiones cambian a distintas edades y difieren del comportamiento en adultos. Los traumatismos de tórax pediátricos son mayormente contusos aumentando los traumatismos penetrantes en adolescentes. Las lesiones más comunes son la contusión pulmonar, hemotórax, neumotórax y fracturas costales las cuales pueden coexistir. Las lesiones de vía aérea, corazón y grandes vasos son raras pero muy graves. La mayoría de los traumatismos torácicos se resuelven con medidas de soporte hemodinámico, respiratorio y drenaje pleural. Es vital reconocer en evaluación inicial aquellas lesiones potencialmente letales, que no dan tiempo a evaluación radiológica.

BACKGROUND: Blunt aortic injuries (BAIs) are traditionally treated as surgical emergencies, with the majority of repairs performed in an urgent fashion within 24 hours, irrespective of the grade of aortic injury. These patients are often underresuscitated and often have multiple other trauma issues that need to be addressed. This study reviews a single center's experience comparing urgent (<24 hours) thoracic endovascular aneurysm repair (TEVAR) versus delayed (>24 hours) TEVAR for Grade III BAI. METHODS: All patients undergoing TEVAR for BAI at a single institution between March 2004 and March 2014 were reviewed (n = 43). Patients with Grade I, II, or IV aortic injuries as well as those who were repaired with an open procedure or who lacked preoperative imaging were excluded from the analysis. Demographics, intraoperative data, postoperative survival, and complications were compared. RESULTS: During this period, there were 43 patients with blunt thoracic aortic injury. There were 29 patients with Grade III or higher aortic injuries. Of these 29 patients, 1 declined surgery, 2 were repaired with an open procedure, 10 underwent urgent TEVAR, and 16 had initial observation. Of these 16, 13 underwent TEVAR in a delayed fashion (median, 9 days; range, 2-91 days), and 3 died of non-aortic-related pathology. Comparing the immediate repair group versus the delayed repair group, there were no significant demographic differences. Trauma classification scores were similar, although patients in the delayed group had a higher number of nonaortic injuries. The 30-day survival was similar between the two groups (9 of 10 vs. 12 of 16), with no mortalities caused by aortic pathology in either group. CONCLUSION: Watchful waiting may be permissible in patients with Grade III BAI with other associated multisystem trauma. This allows for a repair in a more controlled environment. LEVEL OF EVIDENCE: Therapeutic study, level V.

STUDY OBJECTIVE: The NEXUS chest decision instrument identifies a very-low-risk population of patients with blunt trauma for whom chest imaging can be avoided. However, it requires that all 7 National Emergency X-Ray Utilization Study (NEXUS) chest criteria be absent. To inform patient and physician shared decisionmaking about imaging, we describe the test characteristics of individual criteria of the NEXUS chest decision instrument and provide the prevalence of injuries when 1, 2, or 3 of the 7 criteria are present. METHODS: We conducted this secondary analysis of 2 prospectively collected cohorts of patients with blunt trauma who were older than 14 years and enrolled in NEXUS chest studies between December 2009 and January 2012. Physicians at 9 US Level I trauma centers recorded the presence or absence of the 7 NEXUS chest criteria. We calculated test characteristics of each criterion and combinations of criteria for the outcome measures of major clinical injuries and thoracic injury observed on chest imaging. RESULTS: We enrolled 21,382 patients, of whom 992 (4.6%) had major clinical injuries and 3,135 (14.7%) had thoracic injuries observed on chest imaging. Sensitivities of individual test characteristics ranged from 15% to 56% for major clinical injury and 14% to 53% for thoracic injury observed on chest imaging, with specificities varying from 71% to 84% for major clinical injury and 67% to 84% for thoracic injury observed on chest imaging. Individual criteria were associated with a prevalence of major clinical injury between 1.9% and 3.8% and of thoracic injury observed on chest imaging between 5.3% and 11.5%. CONCLUSION: Patients with isolated NEXUS chest criteria have low rates of major clinical injury. The risk of major clinical injury for patients with 2 or 3 factors range from 1.7% to 16.6%, depending on the combination of criteria. Criteria-specific risks could be used to inform shared decisionmaking about the need for imaging by patients and their physicians.

In polytrauma patients a thoracic trauma is one of the most critical injuries and an important trigger of post-traumatic inflammation. About 50% of patients with thoracic trauma are additionally affected by bone fractures. The risk for fracture malunion is considerably increased in such patients, the pathomechanisms being poorly understood. Thoracic trauma causes regional alveolar hypoxia and, subsequently, hypoxemia, which in turn triggers local and systemic inflammation. Therefore, we aimed to unravel the role of oxygen in impaired bone regeneration after thoracic trauma. We hypothesized that short-term breathing of 100% oxygen in the early post-traumatic phase ameliorates inflammation and improves bone regeneration. Mice underwent a femur osteotomy alone or combined with blunt chest trauma 100% oxygen was administered immediately after trauma for two separate 3 hour intervals. Arterial blood gas tensions, microcirculatory perfusion and oxygenation were assessed at 3, 9 and 24 hours after injury. Inflammatory cytokines and markers of oxidative/nitrosative stress were measured in plasma, lung and fracture hematoma. Bone healing was assessed on day 7, 14 and 21. Thoracic trauma induced pulmonary and systemic inflammation and impaired bone healing. Short-term exposure to 100% oxygen in the acute post-traumatic phase significantly attenuated systemic and local inflammatory responses and improved fracture healing without provoking toxic side effects, suggesting that hyperoxia could induce anti-inflammatory and pro-regenerative effects after severe injury. These results suggest that breathing of 100% oxygen in the acute post-traumatic phase might reduce the risk of poorly healing fractures in severely injured patients.
