Removal of Foreign Body in the Rafe Pterigomandibular: Case Report / Remoção de Corpo Estranho Alojado na Rafe Pterigomandibular: Relato de Caso

Introduction: Penetrating lesions in the oral cavity, caused by foreign bodies, is an event of significant clinical relevance and presents itself as an important etiological factor, especially in pediatric patients. Several objects are related to this type of trauma, such as knife blades, nails, pencils, wood, firearm projectile, and glass, among others. Case Report: This report describes a case of removal of a pencil lodged in the left pterygomandibular raphe of a pediatric patient, as well as all the conduct adopted by the team of surgeons. Discussion: Pterygomandibular raphe has an intimate relationship with noble structures, and injuries by penetrating instruments in this region can result in important clinical repercussions. Due to this, it is necessary to have an efficient clinical-anamnesis examination, with adequate analysis of the affected structures, in order to provide a fast and effective treatment. Conclusion: For this, it is essential to have qualified professionals, adequate equipment available, and the proper management of the victim.

Introdução: As lesões penetrantes em cavidade oral, ocasionadas por corpos estranhos, é um evento de relevância clínica significativa e se apresenta como um importante fator etiológico, principalmente, em pacientes pediátricos. Diversos objetos estão relacionados a esse tipo de trauma, como lâmina de faca, prego, lápis, madeira, projétil de arma de fogo, vidro, entre outros.

Manejo del trauma penetrante de cuello en dos hospitales de Bogotá, Colombia / Management of penetrating neck trauma at two hospitals in Bogotá, Colombia

Introducción. El manejo del trauma penetrante de cuello en pacientes estables, según la zona de Monson lesionada, orienta la solicitud de pruebas diagnósticas para identificar lesiones vasculares, de las vías aéreas y del tubo digestivo. Materiales y métodos. Se trata de un estudio observacional, descriptivo y retrospectivo. Se incluyeron pacientes de 15 años o más con trauma penetrante de cuello, que consultaron a los dos hospitales de la Sociedad de Cirugía de Bogotá en un periodo de cinco a seis años. Se recolectó la información demográfica, clínica y de las pruebas diagnósticas practicadas, para determinar su utilidad. Las variables cualitativas se describieron con frecuencias relativas y absolutas, y las cuantitativas, con medias y desviaciones estándar. Resultados. Inicialmente, se incluyeron 148 pacientes, de los cuales 133 fueron catalogados como estables durante la valoración primaria, con un promedio de edad de 33,04 años (desviación estándar, DE=12,9); la mayoría (88,7 %) eran hombres. La mediana de la estancia hospitalaria fue de dos días (rango intercuartílico, RIQ=1-4 días). En la mayoría (117; 87,9 %) de los casos, la herida fue causada con arma cortopunzante. En casi todas las pruebas diagnósticas, se reportaron pocos hallazgos anormales, a excepción de la angiotomografía (angio-TC) que se practicó en 59 pacientes y demostró 43 resultados anormales. Se decidió tratamiento quirúrgico en siete pacientes catalogados como estables al ingreso y, en 14, por resultados anormales de las pruebas diagnósticas. Se presentaron cinco fallecimientos. Conclusión. El examen físico, la observación clínica y la angio-TC son suficientes para identificar lesiones vasculares, de la vía aérea o del tubo digestivo en los pacientes con trauma penetrante de cuello, en hospitales que no son considerados como especializados en trauma

Introduction: Management of penetrating neck trauma in stable patients according to the affected Monson zone directs the diagnostic tests to identify vascular, airway and digestive tract lesions. Materials and methods: A retrospective descriptive observational study was conducted. We included 15 year-old or older patients with penetrating neck trauma that consulted at the two hospitals of the Sociedad de Cirugía in Bogotá, Colombia, during a 5 to 6 year period. Demographic and clinical information was collected, as well as the results of the diagnostic tests applied in order to determine their utility. Qualitative variables were described with relative and absolute frequencies and quantitative variables with median and standard deviations. Results: 148 patients were enrolled initially, of which 133 were classified as stable during the primary assessment, with an average age of 33.04 years (SD: 12.9), the majority being men (88.7%). The median hospital stay was 2 days (IQR=1-4 days). The most frequent wound mechanism was a sharp bladed weapon in 117 cases (87.9%). A low proportion of abnormal findings were reported in the diagnostic tests, except for angiography CT which was performed in 59 patients with 43 with abnormal findings. Surgical management was defined for 7 patients classified as stable at admission and for 14 patients after abnormal findings found in the diagnostic tests. Five deaths were registered. Conclusion: Physical examination, clinical observation and angiography CT are sufficient to identify vascular, airway and digestive lesions in patients with penetrating neck trauma at hospitals that are not considered specialized in trauma

Fatores associados ao óbito e à reposição volêmica em pacientes com trauma por lesões penetrantes / Factors associated with death or volume replacement in patients with trauma due to penetrating injuries

Objective: to evaluate the prognostic factors of volume replacement in patients with trauma due to penetrating injuries. Methods: retrospective cohort study whose data were obtained by analyzing medical records of 544 patients who were admitted to the emergency unit, victims of penetrating trauma. Results: among the victims, 282 (51.9%) suffered stab wound, 262 (48.2%) injury by firearms, 486 (89.3%) were male, 382 (70.2%) were aged between 14 and 30 years. Most who received volume greater than 2000ml, systolic blood pressure ≤90mmHg and mean arterial pressure ≤65mmHg presented more mortality, with p <0.05, p <0.002 and p <0.003, respectively. Conclusion: the limited volume replacement can help in the good prognosis of victims of penetrating trauma.

Avaliar os fatores prognósticos da reposição volêmica em pacientes com trauma por lesões penetrantes. Métodos: estudo de coorte retrospectiva cujos dados foram obtidos através da análise de prontuários de 544 pacientes que deram entrada no serviço de emergência, vítimas de traumatismo penetrante. Resultados: dentre as vítimas, 282 (51,9%) sofreram ferimento por arma branca, 262 (48,2%) ferimento por arma de fogo, 486 (89,3%) eram do sexo masculino, com idade entre 14 e 30 anos 382 (70,2%). A maioria que recebeu fluído maior que 2000ml, pressão arterial sistólica ≤90mmHg e pressão arterial média ≤65mmHg, apresentou mais mortalidade, com valor de p<0,05, p<0,002 e p<0,003, respectivamente. Conclusão: a reposição volêmica limitada pode auxiliar no bom prognóstico do paciente vítima de trauma penetrante.

Penetrating cardiac trauma: 20-y experience from a university teaching hospital.

BACKGROUND: Penetrating traumas, including gunshot and stab wounds, are the major causes of cardiac trauma. Our aim was to describe and compare the variables between patients with penetrating cardiac trauma in the past 20 y in a university hospital, identifying risk factors for morbidity and death. METHODS: Review of trauma registry data followed by descriptive statistical analysis comparing the periods 1990-1999 (group 1, 54 cases) and 2000-2009 (group 2, 39 cases). Clinical data at hospital admission, Injury Severity Score (ISS), Glasgow Coma Scale (GCS), and Revised Trauma Score (RTS) were recorded. RESULTS: The incidences of penetrating cardiac injuries were steady within the period of study in the chosen metropolitan area. The two groups were similar regarding age, mechanism of trauma (gunshot × stab), and ISS. Group 1 showed lower systolic blood pressure at admission (mean 87 versus 109 mm Hg), lower GCS (12.9 versus 14.1), lower RTS (6.4 versus 7.3), higher incidence of grade IV-V cardiac lesions (74% versus 48.7%), and were less likely to survive (0.83 versus 0.93). The major risk factor for death was gunshot wound (13 times higher than stab wound), systolic blood pressure < 90 mm Hg, GCS < 8, RTS < 7.84, associated injuries, grade IV-V injury, and ISS > 25. We observed a tendency in mortality reduction from 20.3% to 10.3% within the period of observation. CONCLUSIONS: Several associated factors for mortality and morbidity were identified. In the last decade, patients were admitted in better physiological condition, perhaps reflecting an improvement on prehospital treatment. We observed a trend toward a lower mortality rate.
