Incidence and pattern of traumatic spine injury in a single level I trauma center of southern Iran / 中华创伤杂志(英文版)

PURPOSE@#Spine injury is one of the leading causes of death and mortality worldwide. The objective of this study was to determine the incidence, pattern and outcome of trauma patients with spine injury referred to the largest trauma center in southern Iran during the last 3 years.@*METHODS@#This is a cross-sectional study conducted between March 2018 and June 2021 in the largest trauma center in the southern Iran. The data collection form included the age, sex, injury location (cervical, thoracic, and lumbar), cause of injury (traffic accidents, falls, and assaults), length of hospital stay, injured segment of spine injury, severity of injury, and outcome. Statistical analyzes were performed using SPSS software version 24.@*RESULTS@#Totally 776 cases of spine injury were identified. The spine injury rate was 17.0%, and the mortality rate was 15.5%. Cervical spine injury (20.4%) more often occulted in motorcycle accident, and thoracic spine injury (20.1%) occulted in falls. The highest and lowest rates of spine injurys were related to lumbar spine injury (30.2%) and cervical spine injury (21.5%), respectively. There was a statistically significant relationship between the mechanism of injury and the location of spine injury (p < 0.001). And patients with lumbar spine injury had the highest mortality rate (16.7%). Injury severity score (OR= 1.041, p < 0.001) and length of stay (OR = 1.018, p < 0.001) were strong predictors of mortality in trauma patients with spine injury.@*CONCLUSION@#The results of the study showed that the incidence of traumatic spine injury rate was approximately 17.0% in southern of Iran. Road traffic injury and falls are the common mechanism of injury to spine. It is important to improve the safety of roads, and passengers, as well as work environment, and improve the quality of cars. Also, paying attention to the pattern of spine injury may assist to prevent the missing diagnosis of spine injury in multiple trauma patients.

Epidemiology and estimated economic impact of musculoskeletal injuries in polytrauma patients in a level one trauma centre in Singapore

INTRODUCTION@#Musculoskeletal injuries are the most common reason for surgical intervention in polytrauma patients.@*METHODS@#This is a retrospective cohort study of 560 polytrauma patients (injury severity score [ISS] >17) who suffered musculoskeletal injuries (ISS >2) from 2011 to 2015 in National University Hospital, Singapore.@*RESULTS@#560 patients (444 [79.3%] male and 116 [20.7%] female) were identified. The mean age was 44 (range 3-90) years, with 45.4% aged 21-40 years. 39.3% of the patients were foreign migrant workers. Motorcyclists were involved in 63% of road traffic accidents. The mean length of hospital stay was 18.8 (range 0-273) days and the mean duration of intensive care unit (ICU) stay was 5.7 (range 0-253) days. Patient mortality rate was 19.8%. A Glasgow Coma Scale (GCS) score <12 and need for blood transfusion were predictive of patient mortality (p < 0.05); lower limb injuries, road traffic accidents, GCS score <8 and need for transfusion were predictive of extended hospital stay (p < 0.05); and reduced GCS score, need for blood transfusion and upper limb musculoskeletal injuries were predictive of extended ICU stay. Inpatient costs were significantly higher for foreign workers and greatly exceeded the minimum insurance coverage currently required.@*CONCLUSION@#Musculoskeletal injuries in polytrauma remain a significant cause of morbidity and mortality, and occur predominantly in economically productive male patients injured in road traffic accidents and falls from height. Increasing insurance coverage for foreign workers in high-risk jobs should be evaluated.

Impact of nationwide COVID-19 lockdown on workload and injury patterns of major trauma cases in a regional trauma centre in Singapore

INTRODUCTION@#Singapore instituted lockdown measures from 7 February 2020 to 1 June 2020 in response to the coronavirus disease 2019 (COVID-19) pandemic.@*METHODS@#A retrospective analysis of cases from the national trauma registry was carried out comparing the lockdown period (from 7 February 2020 to 1 June 2020) to the pre-lockdown period (from 7 February 2019 to 1 June 2019). Data extracted included the volume of Tier 1 (injury severity score [ISS] >15) and Tier 2 (ISS 9-15) cases and epidemiology. Subgroup analysis was performed for Tier 1 patient outcomes.@*RESULTS@#Trauma volume decreased by 19.5%, with a 32% drop in Tier 1 cases. Road traffic and workplace accidents decreased by 50% (P < 0.01), while interpersonal violence showed an increase of 37.5% (P = 0.34). There was an 18.1% decrease in usage of trauma workflows (P = 0.01), with an increase in time to intervention for Tier 1 patients from 88 to 124 min (P = 0.22). Discharge to community facilities decreased from 31.4% to 17.1% (P < 0.05). There was no increase in inpatient mortality, length of stay in critical care or length of stay overall.@*CONCLUSION@#There was an overall decrease in major trauma cases during the lockdown period, particularly road traffic accidents and worksite injuries, and a relative increase in interpersonal violence. Redeployment of manpower and hospital resources may have contributed to decreased usage of trauma workflows and community facilities. In the event of further lockdowns, it is necessary to plan for trauma coverage and maintain the use of workflows to facilitate early intervention.

The "weekend effect" does not impact on outcome of trauma laparotomy - Experience from a level 1 trauma centre in New Zealand / 中华创伤杂志(英文版)

PURPOSE@#Trauma centres have been proven to provide better outcomes in developed countries for overall trauma, but there is limited literature on the systematic factors that describe any discrepancies in outcomes for trauma laparotomies in these centres. This study was conducted to examine and interrogate the effect of systematic factors on patients undergoing a trauma laparotomy in a developed country, intending to identify potential discrepancies in the outcome.@*METHODS@#This was a retrospective study of all laparotomies performed for trauma at a level 1 trauma centre in New Zealand. All adult patients who had undergone an index laparotomy for trauma between February 2012 and November 2020 were identified and laparotomies for both blunt and penetrating trauma were included. Repeat laparotomies and trauma laparotomies in children were excluded. The primary clinical outcomes reviewed included morbidity, length of hospital stay, and mortality. All statistical analysis was performed using R v.4.0.3.@*RESULTS@#During the 9-year study period, 204 trauma laparotomies were performed at Waikato hospital. The majority (83.3%) were performed during office hours (170/204), and the remaining 16.7% were performed after hours (34/204). And 61.3% were performed on a weekday (125/204), whilst 38.7% were performed on the weekend/public holiday (79/204). Most of the parameters in office hours and after hours groups had no statistically significant difference, except lactate (p = 0.026). Most of the variables in weekday and weekend groups had no statistically significant difference, except pH, lactate, length of stay, and gastrointestinal complications (p = 0.012, p < 0.001, p = 0.003, p = 0.020, respectively).@*CONCLUSION@#The current trauma system at Waikato hospital is capable of delivering care for trauma laparotomy patients with the same outcome regardless of working hours or after hours, weekday or weekend. This confirms the importance of a robust trauma system capable of responding to the sudden demands placed on it.

Comparing epidemiologic features, outcomes, and diagnostic and therapeutic procedures of traumatic patients before and during COVID-19 pandemic: Data from the National Trauma Registry of Iran / 中华创伤杂志(英文版)

PURPOSE@#To prepare for future possible communicable disease epidemics/pandemics, health care providers should know how the COVID-19 pandemic influenced injured patients. This study aimed to compare epidemiologic features, outcomes, and diagnostic and therapeutic procedures of trauma patients admitted to a university-affiliated hospital before and during the pandemic.@*METHODS@#This retrospective study was performed on data from the National Trauma Registry of Iran. All injured patients admitted to the hospital from July 25, 2016 to March 10, 2021 were included in the study. The patients were excluded if they had hospital length of stay less than 24 h. The injury outcomes, trauma mechanisms, and therapeutic and diagnostic procedures of the 2 periods: before (from July 25, 2016 to February 18, 2020) and during (from February 19, 2020 to March 10, 2021) COVID-19 pandemic were compared. All analyses were performed using STATA version 14.0 software (Stata Corporation, College Station, TX).@*RESULTS@#Totally, 5014 patients were included in the registry. Of them, 773 (15.4%) were registered after the beginning of the COVID-19 pandemic on February 19, 2020, while 4241 were registered before that. Gender, education level, and cause of injury were significantly different among the patients before and after the beginning of the pandemic (p < 0.001). In the ≤ 15 years and ≥ 65 years age groups, injuries decreased significantly during the COVID-19 pandemic (p < 0.001). The frequency of intensive care unit (ICU) admission decreased from 694 (16.4%) to 88 (11.4%) (p < 0.001). The mean length of stay at the hospital (days) and at the ICU (days) declined as follow: 8.3 (SD = 17.2) vs. 5.5 (SD = 6.1), p < 0.001 and 7.5 (SD = 11.5) vs. 4.5 (SD = 6.3), p < 0.022. The frequency of diagnostic and therapeutic procedures before and during the pandemic was as follows, respectively: ultrasonography 905 (21.3%) vs. 417 (53.9%) (p < 0.001), echocardiography 313 (7.4%) vs. 107 (13.8%) (p < 0.001), angiography 1597 (37.7%) vs. 534 (69.1%) (p < 0.001), MRI 166 (3.9%) vs. 51 (6.6%) (p < 0.001), surgery 3407 (80.3%) vs. 654 (84.6%) (p < 0.001), and internal/external fixation 1215 (28.6%) vs. 336 (43.5%) (p < 0.001).@*CONCLUSION@#The pandemic affected the epidemiology of traumatic patients in terms of gender, age, educational level, and trauma mechanism. It changed the outcomes of injured patients: ICU admission, length of stay at the hospital and ICU decreased. The patients received more diagnostic and therapeutic procedures during the pandemic. To be more precise, more research is needed on the details.

Aspects épidémiologiques, diagnostiques et thérapeutiques des traumatismes vertébro-médullaires au Centre Hospitalier Universitaire d'Owendo, Gabon / Spinal cord injury at the Owendo teaching hospital, Gabon. Epidemiology, diagnosis and management

Spinal cord injury constitutes a multidisciplinary therapeutic emergency. It occurs usually in a context of polytrauma. The aim of this study was to describe the management of spinal cord injury admitted to the emergency department of a "trauma center". Methods: This is a prospective observational study carried out at the University Hospital of Owendo, Gabon. Patients admitted to the emergency department of any age for spinal cord injury and having performed a radiological examination were included. Socio-demographic parameters, circumstances and times of onset of trauma, mode of transport, state of consciousness, sensory and motor deficit, American Spinal Injury Association (ASIA) Score, hemodynamic and respiratory status were assessed. Results: During the study period, 850 patients were registered at the emergency department. Among them 112 were admitted for spinal cord injury (3.17%). The average age of the patients was 36 ± 3 years. The male gender accounted for 77% of cases. It concerned in 36% of cases the unemployed. The road accident was incriminated in 61%. Pedestrians were involved in 81% of cases. The clinical evaluation on admission found a sensorimotor deficit in 45 patients (40.17%), there were 11 tetraplegias (10%) and 3 paraplegias (3%). The majority of patients (77.7%) were classified as Fränkel stage A. The lesions were dominated by dislocations of the cervical spine (30.4%). Specialized care was essentially orthopedic in 60.7%. No patient was operated. Conclusion: Spinal cord injuries are "time-dependent" medical and surgical emergencies. A codified organization of pre-hospital care and an efficient "trauma center" are essential factors for the management of this type of traumatic pathology

Electric scooter injuries: Incidence and injury patterns at a level I trauma center / 中华创伤杂志(英文版)

PURPOSE@#Electric scooters (e-scooters) have become an increasingly popular mode of public transportation in recent years. As the incidence of related injuries rises, it is important to understand specific fracture patterns unique to e-scooters and electric bikes (e-bikes) to help guide management. The purpose of this study was to review the prevalence and describe specific fracture patterns of e-scooter and e-bike related injuries at the busiest level 1 trauma center in the borough of Manhattan.@*METHODS@#Chart review to determine mechanism of injury was performed on all patients for whom an orthopedic consult was requested from 1/1/2021 to 12/31/2021. All patients whose injuries were sustained due to an e-scooter or e-bike were further reviewed for demographics, injury characteristics including fracture pattern, and definitive injury management. Any patients who had an orthopedic consult placed for a reason other than an acute injury were excluded. Descriptive statistics are reported as frequency (percentage) for categorical variables and means for continuous variables.@*RESULTS@#Of the 1815 orthopedic consults requested, 1357 (74.8%) were for acute injury management. Of those with acute injuries, 119 (8.8%) sustained 136 e-scooter or e-bike related injuries. There were 92 (77.3%) males at an average age of (33.8 ± 15.7) years. Approximately one-fifth of all patients presented in June 2021 (26, 21.8%). There was a 9.2% rate of open fractures. The 136 injuries were evenly split between the upper and lower extremities, with 57 (47.9%) upper extremity, 57 (47.9%) lower extremity injuries, and 5 (4.2%) concomitant upper and lower extremity injuries. The most common fracture patterns were ankle fractures (16, 11.7%), followed by tibial shaft (14, 10.2%), tibial plateau (13, 9.5%), and radial head fractures (11, 8.0%). There was a 33.3% incidence of associated posterior malleolar fractures in the spiral tibial shaft fractures, 31.0% of posterior malleolar involvement and 18.8% of isolated vertical medial malleolar fractures in the ankle fractures, and 61.5% of posterior comminution in the tibial plateau fractures.@*CONCLUSION@#E-scooter and e-bike related injuries have a high incidence of tibial shaft fractures, ankle fractures, tibial plateau fractures, and radial head fractures. There should be a high index of suspicion for posterior and medial involvement in lower extremity fractures sustained due to e-scooter or e-bikes. Identifying specific fracture patterns seen in e-scooter and e-bike related mechanisms will help guide management of these injuries.

De un centro de trauma a un sistema de trauma en el suroccidente colombiano / From a Trauma Center to a Trauma System in Southwest Colombia

Introducción. El objetivo de este estudio fue evaluar el impacto sobre la mortalidad según el perfil de ingreso a un centro de trauma del suroccidente colombiano, como método para entender las dinámicas de atención del paciente con trauma. Métodos. Se realizó un subanálisis del registro de la Sociedad Panamericana de Trauma asociado a un centro de trauma en el suroccidente colombiano. Se analizaron los pacientes atendidos entre los años 2012 y 2021. Se compararon los pacientes con condición de ingreso directo y aquellos que ingresaron remitidos. Se hicieron análisis de poblaciones de interés como pacientes con trauma severo (ISS > 15) y pacientes con/sin trauma craneoencefálico. Se evaluó el impacto de los pacientes remitidos y su condición al ingreso sobre la mortalidad. Resultados. Se incluyeron 10.814 pacientes. La proporción de pacientes remitidos fue del 54,7 %. Los pacientes que ingresaron remitidos presentaron diferencias respecto a la severidad del trauma y compromiso fisiológico al ingreso comparado con los pacientes con ingreso directo. Los pacientes remitidos tienen mayor riesgo de mortalidad (RR: 2,81; IC95% 2,44-3,22); sin embargo, es el estado fisiológico al ingreso lo que impacta en la mortalidad. Conclusión. Los pacientes remitidos de otras instituciones tienen un mayor riesgo de mortalidad, siendo una inequidad en salud que invita a la articulación de actores institucionales en la atención de trauma. Un centro de trauma debe relacionarse con las instituciones asociadas para crear un sistema de trauma que optimice la atención de los pacientes y la oportunidad

Introduction. This study aims to evaluate the impact on mortality by admission profile to a trauma center in Southwest Colombia between direct and referred patients, as a method to understand the dynamics of trauma care.Methods. A sub-analysis of the Panamerican Trauma Society registry associated with a trauma center in Southwest Colombia was performed. Patients attended between 2012-2021 were analyzed. Patients with direct admission and referred condition were compared. Analyses of populations of interest such as patients with severe trauma (ISS > 15) and patients with/without brain trauma were made. The impact of referred patients and their admission status on mortality was evaluated. Results. A total of 10,814 patients were included. The proportion of referred patients was 54.7%. Patients admitted referred vs. with direct admission have differences regarding trauma severity and physiological compromise on admission. The referred patient has a higher risk of mortality (RR: 2.81; 95% CI 2.44-3.22). There is a high proportion of penetrating trauma by gunshot wounds. However, it is the physiological state at admission that impacts mortality. Conclusion. Patients referred from other institutions have a higher mortality risk, being a health inequity that invites the articulation of institutional actors in trauma care. A trauma center should relate to partner institutions to create a trauma system that optimizes care and timeliness

Competência profissional do enfermeiro na unidade de trauma / Professional competence of nurses in the trauma unit

Objetivo: Analizar la competencia profesional del personal de enfermería en la unidad de trauma. Metodología: Investigación cuantitativa, descriptiva y transversal, que fue desarrollada con 47 profesionales de enfermería. Este grupo se desempeñaba en cuatro sectores de riesgo de la unidad de trauma de un hospital público en el noreste de Brasil. Se aplicó un cuestionario validado sobre la competencia profesional del personal de enfermería en emergencias, compuesto por módulos y dominios, entre ellos variables sociodemográficas, formación profesional, caso ficticio y autoevaluación de las acciones diarias correspondientes a la realidad laboral. La recolección de datos se realizó de julio a septiembre de 2019. Para el análisis de datos, se utilizó estadística descriptiva, el software SPSS y la prueba de chi-cuadrado. Para verificar la significancia, se adoptó un valor de p<0.05. Resultados: Se observó que la mayoría de personas participantes eran del sexo femenino, especialistas y tenían más de una relación laboral. En cuanto a los dominios ''relaciones de trabajo'' y ''práctica profesional'', las personas participantes se autoevaluaron como ''muy competentes'' o ''extremadamente competentes'' en todas las acciones que retratan la realidad de trabajo en que están insertas. En el dominio ''excelencia profesional'', la acción ''participa periódicamente en simulación realista en emergencias'' fue la única evaluada como ''poco competente''. En el caso ficticio, en las tres declaraciones, más de la mitad de las personas participantes calificó el comportamiento de la persona profesional en enfermería como ''extremadamente competente'', ''muy competente'' o ''competente''. Conclusión: La mayoría de profesionales en enfermería no juzgaron correctamente las acciones realizadas por la persona enfermera en el caso ficticio, aunque se autoevaluaron como competentes en las acciones que realizan diariamente. Por lo tanto, el estudio plantea la necesidad de que el servicio invierta en educación permanente vinculada al compromiso profesional para garantizar una atención de alta calidad.

Objetivo: Analisar a competência profissional do enfermeiro na unidade de trauma. Metodologia: Pesquisa quantitativa, descritiva e transversal, desenvolvida com 47 enfermeiros que atuavam em quatro setores da unidade de trauma do hospital público no nordeste brasileiro. Aplicou-se questionário validado sobre a competência profissional do enfermeiro em emergências composto por variáveis sociodemográficas, de formação profissional, um caso fictício e autoavaliação das ações diárias correspondente à realidade do trabalho. A coleta de dados foi realizada nos meses de julho a setembro de 2019. Para análise dos dados, utilizou estatísticas descritivas, o software SPSS e teste do qui-quadrado, para verificar significância adotou-se valor de p<0,05. Resultados: Observou-se que a maioria dos enfermeiros eram do sexo feminino, especialistas e possuíam mais de um vínculo empregatício. Referente aos domínios ''Relações de Trabalho'' e ''Prática Profissional'', os enfermeiros se autoavaliaram como ''muito competente'' ou ''extremamente competente'' em todas as ações que retratam a realidade de trabalho na qual estavam inseridos. No domínio ''Excelência profissional'' a ação ''Participa de simulação realística em emergências periodicamente'' foi a única avaliada como ''pouco competente''. No caso fictício, nas três afirmativas, mais da metade dos enfermeiros julgaram como ''extremamente competente'', ''muito competente'' ou ''competente'' a conduta do enfermeiro no caso. Conclusão: A maioria dos enfermeiros não julgaram corretamente as ações realizadas pelo enfermeiro no caso fictício, mesmo se autoavaliando como competentes nas ações que desempenham diariamente. Sendo assim, o estudo levanta a necessidade do serviço de investir em educação permanente atrelado ao empenho profissional para garantir cuidados de alta qualidade.

Aim: To analyze the professional competence of nurses in trauma units. Methods: This was a quantitative, descriptive and cross-sectional study developed with 47 nurses who work in four areas of the trauma unit of a public hospital in the Northeast of Brazil. A validated Likert Scale questionnaire was applied to evaluate the professional competence of nurses during emergencies; this scale included sociodemographic variables, professional training, a fictitious case, and a self-assessment of daily activities related to the reality of work. The data collection was carried out from July to September 2019. To analyze the data, the researchers employed descriptive statistics or the SPSS software and a qui-square test to verify the significance using a p value of <0.05. Results: It was observed that the majority of the nurses were female specialists who had more than one employment relationship. Regarding the domains ''Work Relations'' and ''Professional Practice'', the nurses assessed themselves as ''highly competent'' or ''extremely competent'' in all the actions that portray the reality of work in which they are immersed. In the ''Professional Excellence'' domain, the action ''periodically participates in realistic simulation in emergencies'' was the only one evaluated as ''little competent''. In the fictitious case, across all three statements, more than half of the nurses rated the nurse's behavior in the case as ''extremely competent'', ''very competent'', or ''competent''. Conclusion: Most of the nurses do not correctly judge the actions performed by the nurse in a fictitious case, even when they self-assess themselves as competent in the actions they perform daily. The study also raises the need for the service to invest in permanent professional training endeavor to guarantee competent labor and high-quality care.

Trauma cervical penetrante: experiencia de un hospital de enseñanza en México / Penetrating cervical trauma: experience of a teaching hospital in Mexico

Introducción. El trauma cervical penetrante es una entidad poco frecuente, con tendencia al alza, de considerable morbimortalidad. Es fundamental conocer su manejo por cirujanos en entrenamiento, quienes en su mayoría son comúnmente los proveedores del tratamiento en las áreas de urgencias. El objetivo de este estudio fue demostrar la experiencia de un centro de trauma en México en el tratamiento de trauma cervical penetrante administrado por cirujanos en entrenamiento. Métodos. Estudio retrospectivo de pacientes con diagnóstico de trauma cervical penetrante sometidos a exploración cervical entre los años 2014 y 2019. Se identificaron 110 expedientes, se excluyeron 26 por falta de datos indispensables para la investigación y se analizaron los datos de 84 pacientes. Resultados. El 96,4 % de los pacientes fueron hombres, la mayoría entre 16 y 50 años (83,3 %) y la zona anatómica II fue la más comúnmente lesionada (65,4 %). Las etiologías más frecuentes fueron heridas por arma cortopunzante (67,9 %) y heridas por proyectil de arma de fuego (25 %). El 95 % de los procedimientos fueron realizados por residentes de cuarto y quinto año. La mediana de días de estancia hospitalaria fue de 2 días. La incidencia de complicaciones fue de 9,5 % y la mortalidad de 1,2 %. Conclusiones. Los cirujanos generales en etapa de formación entrenados en centros de trauma tienen la capacidad de tratar de forma óptima el trauma cervical penetrante sin modificación de las tasas de morbimortalidad descritas en la literatura internacional.

Introduction. Penetrating cervical trauma is a rare entity, with an upward trend, of considerable morbidity and mortality. It is essential to acknowledge its management by surgeons in training, who are usually the providers in the emergency areas. The objective of this study was to demonstrate the experience of a trauma center in Mexico in the treatment of penetrating cervical trauma by surgeons in training. Methods. This was a retrospective study of patients diagnosed with penetrating cervical trauma who underwent cervical examination between 2014 and 2019; 110 records were identified, 26 were excluded due to lack of essential data for the analysis, and the data of 84 patients were included. Results. 96.4% of the patients were men, the majority between 16 and 50 years old (83.3%) and the anatomic zone II was the most frequently injured (65.4%). The most common etiologies were stab wounds (67.9%) and gunshot wounds (25%). Ninety five percent of the procedures were performed by fourth- and fifth-year residents. The median number of days of hospital stay was 2 (2-4) days. The incidence of complications was 9.5% and mortality in 1.2%. Conclusions. General surgeons in the trauma training stage can optimally treat penetrating cervical trauma with the same morbidity and mortality rates described in the international literature.

Impact of the earthquake during COVID-19 lockdown on fracture admission at a tertiary trauma centre in Croatia / 中华创伤杂志(英文版)

PURPOSE@#To determine the impact of an earthquake during COVID-19 lockdown on fracture admission at a tertiary trauma centre in Croatia.@*METHODS@#A case-control study was performed at the tertiary trauma centre registry. Two different periods were studied. The case group included a period during COVID-19 lockdown right after the earthquakes until the end of the confinement period in Croatia. And the control group corresponded to the equivalent period in 2019. We identified all consecutive patients who were admitted due to urgent care requirements for the musculoskeletal trauma. Patient's demographic data and admitting diagnoses were assessed. Data were analyzed by statistical procedures using the program MedCalc statistical software version 16.4.3.@*RESULTS@#We identified 178 emergency admissions due to musculoskeletal trauma. During the COVID-19 lockdown and post-earthquake period, there was a drastic reduction in total admissions (359 vs. 662; p < 0.0001) with an increased proportion of trauma admissions within the emergency admissions (34.9% vs. 26.5%; p = 0.02926, Z = -2.1825). Furthermore, in the case group there was a significant increase in hospital admissions due to ankle/foot trauma (11 vs. 2, p = 0.0126) and a trend towards a decrease in the admissions due to tibia fractures (5 vs. 12, p = 0.0896), however without statistical significance. Also, an increased proportion of women within the group of femoral fractures in both case group (81.6% vs. 52.6%, p = 0.00194, Z = 3.1033) and the control group (82.3% vs. 60.5%, p = 0.0232, Z = 2.2742) was observed. In both analyzed periods, the osteoporotic hip fracture was the most common independent admitting diagnosis.@*CONCLUSION@#It is crucial to understand how natural disasters like earthquakes influence the pattern of trauma admissions during a coexisting pandemic. Accordingly, healthcare systems have to be prepared for an increased influx of certain pathology, like foot and ankle trauma.

Performance and outcome of ressucitative thoracotomies in a southern Brazil trauma center: a 7-year retrospective analysis / Desempenho e desfecho das toracotomias de reanimação realizadas em centro de trauma sul-brasileiro: análise retrospectiva de 7 anos

ABSTRACT Objective: the study aims to analyze the performance and outcome of resuscitation thoracotomy (TR) performed in patients victims of penetrating and blunt trauma in a trauma center in southern Brazil during a 7 years period. Methods: retrospective study based on the analysis of medical records of patients undergoing TR, from 2014 to 2020, in the emergency service of the Hospital do Trabalhador, Curitiba - Paraná, Brazil. Results: a total of 46 TR were performed during the study period, of which 89.1% were male. The mean age of patients undergoing TR was 34.1±12.94 years (range 16 and 69 years). Penetrating trauma corresponded to the majority of indications with 80.4%, of these 86.5% victims of gunshot wounds and 13.5% victims of knife wounds. On the other hand, only 19.6% undergoing TR were victims of blunt trauma. Regarding the outcome variables, 84.78% of the patients had declared deaths during the procedure, considered non-responders. 15.22% of patients survived after the procedure. 4.35% of patients undergoing TR were discharged from the hospital, 50% of which were victims of blunt trauma. Conclusion: the data obtained in our study are in accordance with the world literature, reinforcing the need for a continuous effort to perform TR, respecting its indications and limitations in patients victims of severe penetrating or blunt trauma.

RESUMO Objetivo: analisar o desempenho e o desfecho das toracotomias de reanimação (TR) realizadas nos pacientes vítimas de trauma penetrante e contuso em um hospital de referência em trauma no Sul do Brasil durante um período de sete anos. Métodos: estudo retrospectivo baseado na análise de prontuários de pacientes submetidos a TR, no período de 2014 a 2020, no serviço de emergência do Hospital do Trabalhador, Curitiba - Paraná, Brasil. Resultados: um total de 46 TR foram realizadas durante o período de estudo, dos quais 89.1% eram do sexo masculino. A média de idade dos pacientes submetidos a TR foi de 34.1±12.94 anos (variação de 16 e 69 anos). O trauma penetrante correspondeu pela maioria das indicações de TR com 80.4%, destas 86.5% vítimas de ferimentos por arma de fogo e 13.5% vítimas de ferimento por arma branca. Por outro lado, apenas 19.6% submetidos a TR foram vítimas de trauma contuso. No que se refere as variáveis de desfecho, 84.78% dos pacientes tiveram óbitos declarados durante o procedimento, considerados não respondedores. 15.22% dos pacientes apresentaram sobrevida após o procedimento. 4.35% dos pacientes submetidos à TR tiveram alta hospitalar, sendo 50% pacientes vítimas de trauma contuso. Conclusão: os dados obtidos em nosso estudo estão em conformidade com a literatura mundial, reforçando a necessidade de um esforço contínuo para realização da TR respeitando suas indicações e limitações em pacientes vítimas de trauma grave penetrante ou contuso.

Epidemiological analysis of cardiac trauma victims at a referral trauma hospital: a 5 year case series / Análise epidemiológica das vítimas de trauma cardíaco em um hospital de referência: uma série de casos de 5 anos

ABSTRACT Objective: to describe, analyze, and trace the epidemiological profile for cardiac trauma victims on a referral trauma hospital of a major urban center. Methods: a case series study to review, describe, compile and analyze medical records of all patients sustaining traumatic cardiac injuries, from January 2015 to January 2020 admitted to the referral trauma hospital of Curitiba, Brazil. Patients sustaining traumatic heart injuries were identified using the hospitals database. Patients who died prior to reaching hospital care were excluded. Results: all 22 cases were urban victims, mostly penetrating injuries (12 stab wounds, 9 gunshot wounds); 82% were male; mean age, 37.1 years. 17 cases (77%) occurred during night hours, 15 between Friday and Sunday, and 15 were admitted hemodynamically stable. Only 27% were diagnosed with FAST, the remainder requiring other imaging exams. About incisions, 14 had thoracotomies, 6 median sternotomies and in 2 cases both. Of injuries, 8 affected the right ventricle, 3 right atrium, 9 left ventricle, 1 right coronary sulcus and 1 anterior wall. All had cardiorrhaphy repair. 3 patients died, 17 were discharged and 2 were transferred. 17 received postoperative echocardiograms, revealing ejection fractions ranging 55.1% to 75%. Patients spent a mean of 9.6 days on ICU and a mean of 15.2 days of total hospital stay. The mortality rate was 14%. Conclusions: cardiac traumas predominantly occurred in adult males, due to violent causes, during night hours on weekends. The overall mortality rate found (14%), as well as total hospital stay, accords with the literature.

ABSTRACT Introduction: The aim of our study was to investigate the epidemiological factors involved in suicide attempts seen at a trauma hospital in Curitiba-PR between January 2014 and December 2017. Methods: This is a retrospective study based on the evaluation of hospital mandatory notification forms and database. Patients over 18 years of age who were seen for suicide attempts along a 48-month period were included. Data such as sex, age, marital status, means of aggression, nature of injury, recurrence of attempt, and outcome were analyzed. A total of 283 patients were included in the study and analyzed against the characteristic profile described in the literature. Results: During the study period, there was a constant increase in the number of attempts, significantly higher in females. Despite this increase in women, there was a predominance (1.3:1) of male patients (p < 0.005). The mean age was 34.6 ± 13.25 years and there was no significant gender difference. In general, the main means used was sharp objects (32.8%), followed by intoxication (31.8%), men used more sharp objects, while women, poisoning. Of the total number of patients, 9 (3.2%) died, with a suicides-attempts ratio of 1:31. Conclusion: The profile of the suicide attempt patient has changed compared to previous studies. While the number of men remains higher, the number of women is growing. The increase in indices suggests that public policies should be improved.

Equipos de trauma: realidad mundial e implementación en un país en desarrollo. Descripción narrativa / Trauma teams: global reality and implementation in a developing country. Narrative description

Introducción. El trauma es una de las entidades con mayor morbimortalidad en el mundo. Los equipos especializados en la atención del paciente traumatizado son llamados «equipos de trauma¼. Dichos equipos surgieron de la necesidad de brindar tratamiento oportuno multidisciplinario a individuos con heridas que condicionan gran severidad en la guerra; sin embargo, con el paso del tiempo se trasladaron al ámbito civil, generando un impacto positivo en términos de tiempos de atención, mortalidad y morbilidad. El objetivo de este estudio fue describir el proceso de desarrollo de los equipos de trauma a nivel mundial y la experiencia en nuestra institución en el suroccidente colombiano. Métodos. Se realizó una búsqueda en la base de datos PUBMED, que incluyó revisiones sistemáticas, metaanálisis, revisiones de Cochrane, ensayos clínicos y series de casos. Resultados. Se incluyeron 41 estudios para esta revisión narrativa, y se observó que el tiempo de permanencia en Emergencias, el tiempo de traslado a cirugía, la mortalidad y las complicaciones asociadas al trauma fueron menores cuando se implementan equipos de trauma. Discusión. El diseño de un sistema de atención y valoración horizontal de un paciente con traumatismos severos produce un impacto positivo en términos de tiempos de atención, mortalidad y morbilidad. Se hace necesario establecer los parámetros operativos necesarios en las instituciones de salud de alta y mediana complejidad en nuestro país para implementar dichos equipos de trabajo

Introduction. Trauma is one of the entities with the highest morbidity and mortality in the world. Teams specialized in trauma patient care are called «trauma teams¼. These teams arose from the need to provide timely multidisciplinary treatment to individuals with severe injuries in war; however, with time they moved to the civilian arena, generating a positive impact in terms of care times, mortality and morbidity. The objective of this study was to describe the process of development of trauma teams worldwide and the experience in our institution in southwestern Colombia. Methods. A search of the PUBMED database was carried out, which included systematic reviews, metaanalyses, Cochrane reviews, clinical trials, and case series.Results. Forty-one studies were included for this narrative review, and it was observed that the length of stay in the ER, the time of transfer to surgery, mortality and complications associated with trauma were lower when trauma teams are implemented. Discussion. The design of a horizontal care and assessment system for a patient with severe trauma produces a positive impact in terms of care times, mortality and morbidity. It is necessary to establish operational parameters in high and medium complexity health institutions in our country to implement such work teams

Comparison of acute sports injury between recreational skiers and skiers / 北京大学学报(医学版)

OBJECTIVE@#To compare and analyze the difference between the injuries of recreational skiers in public ski resorts and those of skiing athletes in official competitions, and to explore the suggestions of medical insurance for these two types of skiers.@*METHODS@#The injury data of recreational skiers in Chongli District, Zhangjiakou City, Hebei Province during 2018-2019 and 2019-2020 snow seasons, and the injury data of skiers in two official international skiing competitions during 2019-2020 snow season and domestic test events in Chongli District of 2021 Winter Olympic Games were analyzed retrospectively, and the similarities and differences were compared.@*RESULTS@#A total of 1 187 injuries occurred to recreational skiers in the two public ski resorts during the 2018-2019 snow season, with an injury rate of 0.3%.There were 1 277 injury sites in total, and the most frequent injury sites were head and neck (230 cases, 18.0%), followed by knee joint (204 cases, 16.0%) and lower extremity (131 cases, 10.3%). Thirty-one skiers were injured in the two official international skiing competitions in the 2019-2020 and 2020-2021 snow season, and in the domestic test competitions in the 2021 Winter Olympic Games, and the injury rates were 11.5%, 17.2% and 12.0%, respectively. There were 37 injury sites in total, among which 11 (29.7%) were in the head and neck, followed by 6 (16.2%) in the knee joint and 5 (13.6%) in the chest, rib and abdomen.@*CONCLUSION@#In order to better guarantee the safety of skiers and timely provide corresponding medical help, safety facilities and technical guidance should be added to the snow resort for leisure skiing, and medical stations should be set up in the snow resort. As the formal ski racing for skiing athletes during the game has 30 to 80 times higher injury ratesthan recreational skiers, and compared with the recreational skiing, head and neck injury rate is higher, and the damage is much heavier, more complete first aid facilities and experienced medical workers are, needed so the field should be equipped with the circuit inside the quantities, track fixed outside the clinic, surrounding referral hospitals set up trauma centers to provide athletes with more timely medical care.

What's new in trauma 2020 / 中华创伤杂志(英文版)

Throughout the past 2020, the pandemic COVID-19 has caused a big global shock, meanwhile it brought a great impact on the public health network. Trauma emergency system faced a giant challenge and how to manage trauma under the pandemic of COVID-19 was widely discussed. However, the trauma treatment of special population (geriatric patients and patients taking anticoagulant drugs) has received inadequate attention. Due to the high mortality following severe traumatic hemorrhage, hemostasis and trauma-induced coagulopathy are the important concerns in trauma treatment. Sepsis is another topic should not be ignored when we talking about trauma. COVID-19 itself is a special kind of sepsis, and it may even be called as serious systemic infection syndrome. Sepsis has been become a serious problem waiting to be solved urgently no matter in the fields of trauma, or in intensive care and infection, etc. This article reviewed the research progress in areas including trauma emergency care, trauma bleeding and coagulation, geriatric trauma and basic research of trauma within 2020.

Observational study of patients with occipital condyle fracture at a brazilian referral trauma center / Estudo observacional de pacientes com fratura de côndilo ocipital em centro de referência em trauma no brasil

ABSTRACT Objective: to evaluate the clinical-epidemiological characteristics, treatment, and evolution of patients with occipital condyle fracture (OCF) at one of the largest referral trauma centers in Latin America. Methods: this was a retrospective observational study of OCF identified from trauma cases admitted between December 2011 and December 2019 by the neurosurgery team at a Type 3 trauma center. Results: a total of twenty-eight occipital condyle fractures were identified in twenty-six patients. The incidence was less than 0.2% per year and more common in male patients (4:1 ratio) involved in traffic accidents. The mean age was 42.08 years. Anderson and Montesano type II and Tuli type 1 were the most frequent (67.9% and 89.3%, respectively) and no case presented C0-C1-C2 instability. All patients were treated with a cervical collar for 3 to 6 months. About 65% of the patients exhibited good progression (Glasgow Outcome Scale equal to 4), and the severity of traumatic brain injury was the main determinant for negative outcomes. Conclusion: the findings of this study are in accordance with available literature data. The use of external stabilization with a cervical collar is reinforced for the treatment of stable lesions, even when these are bilateral. Assessment of the patients' follow-up results in the studied sample may contribute with useful information for the treatment of occipital condyle fractures.

RESUMO Objetivo: avaliar o perfil clínico-epidemiológico, o tratamento e a evolução de pacientes com fraturas do côndilo occipital (FCO) em um dos maiores centros especializados em trauma na América Latina. Método: este é um estudo observacional retrospectivo de FCO identificadas em casos de trauma que foram atendidos no período de Dezembro de 2011 a Dezembro de 2019 pela equipe de trauma de centro de trauma Tipo 3. Resultados: um total de vinte e oito fraturas do côndilo occipital foram identificadas em 26 pacientes. A incidência foi inferior a 0.2% ao ano e mais comum em pacientes do sexo masculino (proporção 4:1) envolvidos em acidentes de trânsito. A idade média foi de 42.08 anos. O Tipo II de Anderson e Montesano e o Tipo 1 de Tuli foram os mais frequentes (67.9% e 89.3%, respectivamente) e nenhum caso teve instabilidades C0C1C2. Todos os pacientes foram tratados com colar cervical por período de 3 a 6 meses. Cerca de 65% dos pacientes apresentaram boa evolução (Escala de Resultados de Glasgow maior ou igual a 4), e a gravidade da lesão cerebral foi o principal determinante para os resultados negativos. Conclusão: os achados deste estudo são similares a dados disponíveis na literatura. O uso de colar cervical para estabilização externa é reforçado para o tratamento de lesões estáveis, mesmo quando bilaterais. A avaliação dos resultados do acompanhamento dos pacientes na amostra estudada pode contribuir com informações úteis para o tratamento de fraturas de côndilo occipital.
