RESUMO

INTRODUCTION: Outcomes from trauma at the major referral hospital [Hospital Nacional de San Benito (HNSB)] in El Petén, Guatemala, have not been analyzed. Empirical evidence demonstrated a high number of motorcycle accidents (MAs). We hypothesized a large incidence of head trauma with poor outcomes in MAs compared to all other forms of blunt trauma. METHODS: Our hypothesis was tested by performing a community observational study and a retrospective chart review in El Petén, Guatemala. An independent observer catalogued 100 motorcycle riders on the streets of El Petén for riding practices as well as helmet utilization. HNSB does not have electronic medical records. For this study, we performed a retrospective chart review of randomly selected nonconsecutive trauma admission at HNSB between March 2018 and June 2023. Blunt trauma was compared between MAs versus all others. Variables were examined by parametric and nonparametric tests as well as contingency table analyses. RESULTS: Most motorcycles riders involved multiple individuals (2.61 ± 0.79/motorcycle). Seventy riders included children (median = 1.0 [Q1-Q3 range = 1.0-3.0]/motorcycle). Overall, only three riders were wearing helmets. Forty-one were women. Of patients presenting to HNSB with trauma, 91 charts were reviewed (33.0 [20.0-37.0] y old; male 89%), 76.7% were blunt, and 23.3% were penetrating trauma. Within blunt trauma, 57.1% were MAs versus 42.9% all others; P = 0.13. MAs were younger (29.5 [20.0-37.0] versus 34.0 [21.8-45.8] y old; P < 0.05) and of similar gender (male 82.5% versus 96.6%; P = 0.1). More MAs had a computed tomography (70.0% versus 30.0%; P < 0.01) and they were more likely to present with head trauma (72.5% versus 46.7%; P = 0.04) but similar Glasgow Coma Scale (15.0 [13.5-15.0] versus 15.0 [12.5-15.0]; P = 0.7). MAs were less likely to require surgical intervention (37.5% versus 56.7%; P = 0.05) but had similar hospital length of stay (4.0 [2-6] versus 4.0 [2-10.5] d; P = 0.5). CONCLUSIONS: Unsafe motorcycle practices in El Petén are staggering. Most trauma at HNSB is blunt, and likely from MAs. More patients with MAs presented with head trauma. However, severe trauma might be transferred to higher level hospitals or mortality might occur on scene, which will need further investigations. Assessment of mortality from trauma admissions is ongoing. These findings should lead to enforcement of safe motorcycle practices in El Petén, Guatemala.

RESUMO

Penetrating aortic injuries are infrequent. Its incidence is unknown because most patients die of hemorrhage even before they receive adequate treatment. Aortic wounds generally require conventional thoracotomy/laparotomy repair and are related to high mortality rates. Recently with the advent of endovascular techniques, most authors prefer endovascular management when feasible due to better (still poor) outcomes. The short- and mid-term results of immediate endovascular repair of traumatic aortic injuries are promising, especially when compared with open surgical treatment, indicating that endovascular therapy is preferable in patients with multi-trauma and traumatic ruptures of the thoracic aorta. Here we present the diagnosis and treatment of a 30 years-old male patient with multiple traumatic stab wounds, including anterior aortic laceration with a grade II aortic lesion successfully managed with an endovascular stent graft.

RESUMO

BACKGROUND: Penetrating arrow injuries of the head and neck are exceedingly rare in pediatric patients. This pathology has high morbidity and mortality because of the presence of vital organs, the airway, and large vessels. Therefore, the treatment and removal of an arrow is a challenge that requires multidisciplinary management. CASE SUMMARY: A 13-year-old boy was brought to the emergency room after an arrow injury to the frontal region. The arrowhead was lodged in the oropharynx. Imaging studies showed a lesion of the paranasal sinuses without compromising vital structures. The arrow was successfully removed by retrograde nasoendoscopy without complications, and the patient was discharged. CONCLUSION: Although rare, maxillofacial arrow injuries have high morbidity and mortality and require multidisciplinary management to preserve function and aesthetics.

RESUMO

Introducción: El trauma penetrante de la arteria vertebral es extremadamente infrecuente. Objetivo: Aportar evidencia clínica mediante la revisión de una serie de casos. Materiales y Método: Se analizan cuatro casos de trauma penetrante con compromiso de la arteria vertebral entre los años 2020 y 2021, manejados en la unidad de trauma y urgencias del Complejo Asistencial Dr. Sótero del Río. Resultados: Se presentan cuatro casos clínicos relatando su proceso diagnóstico y manejo. Discusión: La evidencia de compromiso traumático de arteria vertebral es escasa. Reconocer su compleja anatomía y variada clínica resultan trascendentales para su adecuado manejo. Ante sospecha de este tipo de lesión, la angiografía por tomografía computada es el estudio de elección cuando se presentan hemodinámicamente estables. El abanico de opciones terapéuticas incluyen: observación, terapia antitrombótica o con antiagregantes, terapia endovascular o cirugía abierta. Conclusión: El trauma penetrante de arteria vertebral es una condición infrecuente, sin embargo, su diagnóstico y manejo deben ser conocidos por el cirujano.

Introduction: Traumatic involvement of the vertebral artery is extremely rare and difficult to diagnose. Objective: To provide clinical evidence by reviewing a case series. Materials and Method: We analyze four cases of penetrating trauma with involvement of the vertebral artery between 2020 and 2021, managed in the trauma and emergency unit of the Dr. Sótero del Río Care Complex. Results: Four clinical cases are presented describing diagnosis and management process. Discussion: There is little evidence of traumatic involvement of the vertebral artery. Recognizing its complex anatomy and varied clinic are transcendental for its proper management. When this type of lesion is suspected, computed tomography angiography is the choice study when hemodynamically stable. The range of therapeutic options include observation, antithrombotic or antiplatelet therapy, endovascular therapy or open surgery. Conclusion: Penetrating trauma of the vertebral artery is an uncommon condition, however, its diagnosis and management should be known to the surgeon.

RESUMO

Introducción: Las perforaciones del esófago cervical por traumas externos son lesiones raras asociadas con una morbilidad significativa. Los mecanismos primarios son los traumatismos penetrantes por heridas de bala, cerca del 80 por ciento de los casos, seguidas de las heridas con armas cortopunzantes en el 15 al 20 por ciento. Objetivo: Describir los criterios actuales sobre la conducta y enfoque terapéutico ante el trauma penetrante de esófago cervical. Métodos: Se realizó revisión descriptiva narrativa, de fuentes primarias y secundarias que abordaron el tema durante el primer semestre del año 2021. Los criterios de selección de los artículos a examinar fueron determinados, entre otros, por el objetivo de la actual revisión. Desarrollo: El estándar diagnóstico para estas lesiones, en ausencia de inestabilidad hemodinámica, se basó en estudios como el esofagograma, la endoscopia y la tomografía. La reparación primaria con o sin reforzamiento fue la opción más utilizada, aunque las condiciones locales y tipo de lesión en esófago cervical marcan en gran medida el proceder a realizar. Conclusiones: Las lesiones traumáticas del esófago cervical son raras pero muy mórbidas. El tratamiento depende de la ubicación de la perforación y cualquier lesión concurrente. La mayoría de los casos son susceptibles de reparación primaria con refuerzo de colgajo. Otros principios del tratamiento incluyen el drenaje adecuado alrededor de la reparación, la descompresión del esófago y el estómago (mediante sonda nasogástrica o sonda de gastrostomía) y nutrición enteral distal (yeyunostomía de alimentación). El cirujano ha de ser incisivo en los esfuerzos por descubrir la lesión de forma temprana y manejarla adecuadamente(AU)

Introduction: Cervical esophageal perforations for external trauma are rare injuries associated with a significant morbidity. The primary mechanisms are penetrating trauma for gunshot wounds, accounting for about 80 percent of cases, followed by sharp weapon injuries, accounting for 15 percent to 20 percent. Objective: To describe the current criteria on the behavior and therapeutic approach to cervical esophageal penetrating trauma. Methods: A descriptive narrative review was carried out of primary and secondary sources that addressed the subject during the first semester of the year 2021. The selection criteria of the articles to be examined were determined, among others, by the objective of the current review. Development: The standard diagnosis for these lesions, in the absence of hemodynamic instability, was based on studies such as esophagogram, endoscopy and tomography. Primary repair with or without reinforcement was the most commonly used option, although local conditions and type of lesion in cervical esophagus largely mark the procedure to be performed. Conclusions: Traumatic cervical esophageal injuries are rare but very morbid. Their treatment depends on the location of the perforation and any concurrent injury. Most cases are amenable to primary repair with flap reinforcement. Other principles of treatment include adequate drainage around the repair, decompression of the esophagus and stomach (by nasogastric tube or gastrostomy tube), as well as distal enteral nutrition (feeding jejunostomy). The surgeon must be incisive in efforts to discover the injury early and manage it appropriately(AU)

RESUMO

The high incidence and prevalence of facial trauma makes it important to consider related injuries and possible complications that may arise as a result. Penetrating trauma to the face, although not common, requires a surgeon with knowledge of the anatomy and physiology of the injured area and injury patterns. We present a case of penetrating trauma to the face that was caused by a blunt object (stake) resulting from the felling of a palm tree. We describe the transoral management that was performed and the multidisciplinary support that allowed optimal management of the injury without complications, including functional or aesthetic sequelae.

RESUMO

PURPOSE: The purpose of this study was to examine the association of REBOA and mortality in a group of patients with penetrating trauma to the torso, treated in a level-I trauma center from Colombia. METHODS: In a retrospective cohort study, patients with penetrating trauma, requiring emergency surgery, and treated between 2014 and 2018, were included. The decision to use or not use REBOA during emergent surgery was based on individual surgeon's opinion. A propensity score (PS) was calculated after adjusting for age, clinical signs on admission (systolic blood pressure, cardiac rate, Glasgow coma scale), severe trauma in thorax and abdomen, and the presence of non-compressive torso hemorrhage. Subsequently, logistic regression for mortality was adjusted for the number of red blood cells (RBC) transfused within the first six hours after admission, injury severity score (ISS), and quintiles of PS. RESULTS: We included 345 patients; 28 of them (8.1%) were treated with REBOA. Crude mortality rates were 17.9% (5 patients) in REBOA group and 15.3% (48 patients) in control group (p = 0.7). After controlling for RBC transfused, ISS, and the PS, the odds of death in REBOA group was 78% lower than that in the control group (odds ratio [OR] 0.20, 95% confidence interval [95%CI] 0.05-0.77, p = 0.01). CONCLUSION: We found that, when compared to no REBOA use, patients treated with REBOA had lower risk-adjusted odds of mortality. These findings should be interpreted with caution and confirmed in future comparative studies, if possible.

RESUMO

Abstract Laryngotracheal trauma is rare but potentially life-threatening as it implies a high risk of compromising airway patency. A consensus on damage control management for laryngotracheal trauma is presented in this article. Tracheal injuries require a primary repair. In the setting of massive destruction, the airway patency must be assured, local hemostasis and control measures should be performed, and definitive management must be deferred. On the other hand, management of laryngeal trauma should be conservative, primary repair should be chosen only if minimal disruption, otherwise, management should be delayed. Definitive management must be carried out, if possible, in the first 24 hours by a multidisciplinary team conformed by trauma and emergency surgery, head and neck surgery, otorhinolaryngology, and chest surgery. Conservative management is proposed as the damage control strategy in laryngotracheal trauma.

Resumen El trauma laringotraqueal es poco frecuente, pero con alto riesgo de comprometer la permeabilidad la vía aérea. El presente artículo presenta el consenso de manejo de control de daños del trauma laringotraqueal. En el manejo de las lesiones de tráquea se debe realizar un reparo primario; y en los casos con una destrucción masiva se debe asegurar la vía aérea, realizar hemostasia local, medidas de control y diferir el manejo definitivo. El manejo del trauma laríngeo debe ser conservador y diferir su manejo, a menos que la lesión sea mínima y se puede optar por un reparo primario. El manejo definitivo se debe realizar durante las primeras 24 hora por un equipo multidisciplinario de los servicios de cirugía de trauma y emergencias, cirugía de cabeza y cuello, otorrinolaringología, y cirugía de tórax. Se propone optar por la estrategia de control de daños en el trauma laringotraqueal.

RESUMO

PURPOSE: The objective of this study was to evaluate the implementation of a new single-pass whole-body computed tomography Protocol in the management of patients with severe trauma. METHODS: This was a descriptive evaluation of polytrauma patients who underwent whole-body computed tomography. Patients were divided into three groups: 1. Blunt trauma hemodynamically stable 2. Blunt trauma hemodynamically unstable and 3. Penetrating trauma. Demographics, whole-body computed tomography parameters and outcome variables were evaluated. RESULTS: Were included 263 patients. Median injury severity score was 22 (IQR: 16-22). Time between arrival to the emergency department and completing the whole-body computed tomography was under 30 minutes in most patients [Group 1: 28 minutes (IQR: 14-55), Group 2: 29 minutes (IQR: 16-57), and Group 3: 31 minutes (IQR: 13-50; p= 0.96)]. 172 patients (65.4%) underwent non-operative management. The calculated and the real survival rates did not vary among the groups either [Group 1: TRISS 86.4% vs. real survival rate 85% (p= 0.69); Group 2: TRISS 69% vs. real survival rate 74% (p= 0.25); Group 3: TRISS 93% vs. real survival rate 87% (p= 0.07)]. CONCLUSION: This new single-pass whole-body computed tomography protocol was safe, effective and efficient to decide whether the patient with severe trauma requires a surgical intervention independently of the mechanism of injury or the hemodynamic stability of the patient. Its use could also potentially reduce the rate of unnecessary surgical interventions of patients with severe trauma including those with penetrating trauma.

INTRODUCCIÓN: El objetivo de este estudio fue evaluar la implementación de un nuevo protocolo de tomografía computarizada corporal total para el manejo de pacientes con trauma severo. MÉTODOS: Este estudio es una evaluación descriptiva de pacientes que recibieron tomografía computarizada corporal total. Los pacientes fueron divididos en 3 grupos: 1. Trauma cerrado hemodinámicamente estables, 2. Trauma cerrado hemodinámicamente inestables y 3. Trauma penetrante. Se evaluaron las características demográficas, parámetros relacionados con la técnica y los desenlaces de los pacientes. RESULTADOS: Se incluyeron 263 pacientes. La mediana del puntaje de severidad de la lesión fue 22 (RIQ: 16-22). El tiempo entre el ingreso a urgencias y completar la tomografía corporal total fue menor a 30 minutos en la mayoría de pacientes [Grupo 1: 28 minutos (RIQ: 14-55), Grupo 2: 29 minutos (RIQ: 16-57), y Grupo 3: 31 minutos (RIQ: 13-50; p= 0.96). 172 pacientes (65.4%) recibieron manejo no operatorio. Las tasas de supervivencia calculadas y reales no difirieron entre ninguno de los grupos [Grupo 1: TRISS 86.4% vs. Tasa real de supervivencia 85% (p= 0.69); Grupo 2: TRISS 69% vs. Tasa real de supervivencia 74% (p= 0.25); Grupo 3: TRISS 93% vs. Tasa real de supervivencia 87% (p= 0.07)]. CONCLUSIÓN: Este nuevo protocolo de tomografía corporal total de un solo pase fue seguro, efectivo y eficiente para definir si los pacientes con trauma severo requieren o no una intervención quirúrgica. Su uso podría reducir la tasa de intervenciones quirúrgicas innecesarias en estos pacientes incluyendo los que se presentan con trauma penetrante.

RESUMO

BACKGROUND: Violent trauma with penetrating injuries is a relevant public health issue. Penetrating abdominal wounds cause 90-95% of vascular injuries, which not only have high associated morbidity and lethality, but also involve high attention costs. Cost analysis in hospitals has become a topic of great interest, as it justifies changes in hospital organization and management. OBJECTIVE: Determine the cost of gunshot abdominal vascular injuries for the patient, his family and the hospital. MATERIAL AND METHODS: We drove an observational, descriptive, prospective and longitudinal study of patients with of gunshot abdominal vascular injuries admitted in the Mexican Red Cross Trauma Center in the Federal District from January 1st to October 31st, 2018. RESULTS: 8149 patients were admitted in the emergency department, 149 with a diagnosis of gunshot injury, of which 6 (0.07%) had abdominal vascular injury. The total cost of medical care these patients was on average $174,770.79 (median $132,999.50) per capita, amount that surpasses their annual income and implies an institutional absorption of expenditure up to 95.5%. CONCLUSIONS: Institutional investment on the attention of high-impact pathologies and the development of strategies that facilitate access to health services are a real and priority necessity.

ANTECEDENTES: El trauma violento con lesiones penetrantes es un problema de salud pública relevante. Las heridas penetrantes abdominales causan el 90-95% de las lesiones vasculares, las cuales tienen elevada morbilidad asociada y letalidad, e implican elevados costos de atención. El análisis de costos en los hospitales es de gran interés, pues permite justificar cambios en la organización y la gestión hospitalaria. OBJETIVO: Determinar el costo de las lesiones vasculares abdominales por proyectil de arma de fuego para el paciente, su familia y el hospital. MATERIAL Y MÉTODOS: Se llevó a cabo un estudio observacional, descriptivo, prospectivo y longitudinal de pacientes con lesiones vasculares abdominales por proyectil de arma de fuego que ingresaron en el Centro de Trauma de Cruz Roja Mexicana en Ciudad de México entre enero y octubre de 2018. RESULTADOS: Ingresaron 8149 pacientes, 149 con diagnóstico de herida por proyectil de arma de fuego, de los cuales el 0.07% tuvieron lesión vascular abdominal. El costo total de la atención médica fue en promedio de $174,770.79 (mediana $132,999.50) por persona, el cual supera el ingreso anual de esos pacientes e implica una absorción institucional del gasto de hasta el 95.5%. CONCLUSIONES: La inversión institucional en la atención de patologías con alto impacto y el desarrollo de estrategias para facilitar el acceso a servicios de salud son una necesidad prioritaria real.
