Tratamiento de las fracturas por herida de arma de fuego: revisión bibliográfica sistematizada / Treatment of gunshot wound fractures: systematic review of the literature / Tratamento de fraturas por arma de fogo: revisão bibliográfica sistematizada

Introducción: Las fracturas por heridas de arma de fuego son un motivo de consulta habitual en nuestro país. Existe gran variabilidad de conductas respecto a su tratamiento. El objetivo principal de este trabajo es analizar los distintos tratamientos y sus indicaciones. Materiales: Se realizó una revisión sistematizada de la literatura en las bases de datos Pubmed y Scielo. Se incluyeron artículos con fracturas por herida de arma de fuego en miembros superiores e inferiores, excluyendo la mano. Se analizó: tratamiento (ortopédico o quirúrgico), debridamiento, antibioticoterapia y complicaciones. Resultados: Se obtuvieron 19 artículos que cumplían los criterios de inclusión y exclusión. Los artículos tuvieron un Nivel de Evidencia tipo 2b, 3 y 4. Conclusiones: Los artículos analizados tienen un bajo nivel de evidencia. La fijación quirúrgica es variable y depende de la topografía ósea, la lesión de partes blandas y las lesiones asociadas. El debridamiento profundo está relacionado con mayores índices de infección. Las fracturas estables de tratamiento ortopédico no deberían debridarse ya que aumenta los índices de infección. Debería realizarse antibioticoterapia intravenosa inicial en todos los pacientes, la terapia posterior es discutida.

Introduction: Fractures due to gunshot wounds are a common reason for consultation in our country. There is great variability of conduct regarding its treatment. The main objective of this work is to analyze the different treatments and their indications. Materials: A systematic review of the literature was carried out in the Pubmed and Scielo databases. Articles with fractures due to gunshot wounds in the upper and lower limbs (excluding the hand) were included. We analyzed: treatment (orthopedic or surgical), debridement, antibiotic therapy and complications. Results: 19 articles were obtained that met the inclusion and exclusion criteria. The articles had a Level of Evidence type 2b, 3 and 4. Conclusions: The articles analyzed have a low level of evidence. Surgical fixation is variable and depends on bone topography, soft tissue injury, and associated injuries. Deep debridement is associated with higher rates of infection. Stable orthopedically treated fractures should not be debrided as this increases infection rates. Initial intravenous antibiotic therapy should be performed in all patients, subsequent therapy is discussed.

Introdução: As fraturas por ferimentos por arma de fogo são motivo comum de consulta em nosso país. Há grande variabilidade de conduta quanto ao seu tratamento. O objetivo principal deste trabalho é analisar os diferentes tratamentos e suas indicações. Materiais: Foi realizada revisão sistemática da literatura nas bases de dados Pubmed e Scielo. Foram incluídos artigos com fraturas por arma de fogo em membros superiores e inferiores, excluindo a mão. Foram analisados: tratamento (ortopédico ou cirúrgico), desbridamento, antibioticoterapia e complicações. Resultados: foram obtidos 19 artigos que atenderam aos critérios de inclusão e exclusão. Os artigos tinham Nível de Evidência tipo 2b, 3 e 4. Conclusões: Os artigos analisados ​​apresentam baixo nível de evidência. A fixação cirúrgica é variável e depende da topografia óssea, lesão de tecidos moles e lesões associadas. O desbridamento profundo está associado a maiores taxas de infecção. Fraturas estáveis ​​tratadas ortopedicamente não devem ser desbridadas, pois isso aumenta as taxas de infecção. A antibioticoterapia intravenosa inicial deve ser realizada em todos os pacientes, a terapia subsequente é discutida.

Estudo dos protocolos de traumatologia de lesão por projétil de arma de fogo: revisão de literatura / Study of the traumatology protocols for gunshot injuries: literature review

As armas de fogo são instrumentos letais que estão relacionados a uma grande quantia de homicídios no Brasil, além de traumas e violências. Assim, o atendimento pré-hospitalar e hospitalar é importante na tentativa de diminuir os índices de mortalidade por causas externas. Esta revisão de literatura teve como objetivo demonstrar as formas protocoladas de atendimento atuais a um paciente com trauma por projétil de arma de fogo (AU).

Firearms are lethal instruments that are related to a large amount of homicides in Brazil, as well as traumas and violence. Thus, pre-hospital and hospital care is important in the attempt to reduce mortality rates due to external causes. This literature review aimed to demonstrate the current protocol forms of care for a patient with gunshot wound. (AU)

Transmediastinal gunshot wound in a pregnant patient with stable hemodynamics

Abstract Transmediastinal gunshot wounds (TGWs) may lead to life-threatening injuries of vital organs such as large vessels, the esophagus, and lungs. Although they are not commonly encountered in pregnant women, additional caution should be given to these patients. Physical examination for the diagnosis and the choice of treatment modality contain controversial points in hemodynamically stable patients, and resuscitation has excessive importance due to physiological changes in pregnancy. We present a hemodynamically stable 26-week pregnant woman brought to the emergency department for TGW. She had a 1-cm diameter of bullet entrance hole on the right anterior 4th intercostal space, 2 cm lateral to the sternum, and a 3-cm diameter exit hole on the right posterior 12th intercostal space on the midscapular line.With our conservative approach, she had an uncomplicated pregnancy period, and gave birth to a healthy baby at term.

Endovascular repair of a penetrating axillary artery injury

Abstract We report a 16-year-old boy who sustained a gunshot injury on his upper left side of the chest that resulted in an injury to the left axillary artery and was treated with endovascular repair. An endovascular repair has been increasingly accepted for the management of hemorrhage in critically ill trauma patients; using covered endovascular stents provides an alternative modality for both controlling hemorrhage and preserving flow.

Analysis of combat casualties admitted to the emergency department during the negotiation of the comprehensive Colombian process of peace / Análisis de los soldados heridos en combate admitidos al departamento de emergencias durante la negociación del proceso de paz en Colombia

Abstract Aim: Our objective was to describe the variations in casualties admitted to the emergency department during the period of the negotiation of the comprehensive peace agreement in Colombia between 2011 and 2016. Methods: A retrospective study of all hostile military casualties managed at a regional Level I trauma center from January 2011 to December 2016. Patients were subsequently divided into two groups: those seen before the declaration of the process of peace truce (November 2012) and those after (negotiation period). Variables were compared with respect to periods Results: A total of 448 hostile casualties were registered. There was a gradual decline in the number of admissions to the emergency department during the negotiation period. The number of soldiers suffering blast and rifle injuries also decreased over this period. In 2012 there were nearly 150 hostile casualties' admissions to the ER. This number decreased to 84, 63, 32 and 6 in 2013, 2014, 2015 and 2016 respectively. Both, the proportion of patients with an ISS ≥9 and admitted to the intensive care unit were significantly higher in the period before peace negotiation. From August to December/2016 no admissions of war casualties were registered. Conclusion: We describe a series of soldiers wounded in combat that were admitted to the emergency department before and during the negotiation of the Colombian process of peace. Overall, we found a trend toward a decrease in the number of casualties admitted to the emergency department possibly in part, as a result of the period of peace negotiation.

Resumen Objetivo: Describir las variaciones en los soldados heridos en combate admitidos al departamento de emergencias durante el periodo de negociación del proceso de paz colombiano entre el 2011 y el 2016. Métodos: Estudio retrospectivo de todos los soldados heridos en combate que fueron manejados en un centro de trauma desde Enero del 2011 a Diciembre del 2016. Los pacientes se dividieron en dos grupos: aquellos que ingresaron al departamento de emergencias antes de la tregua del proceso de paz (Noviembre 2012) y aquellos que ingresaron durante la negociación. Los grupos se compararon con respecto a los periodos de tiempo. Resultados: Un total de 448 soldados heridos en combate fueron incluidos. Hubo una disminución gradual en el número de admisiones durante el periodo de negociación. Además, el número de soldados que sufrieron heridas por explosiones y fusiles disminuyó durante este periodo. En el 2012 se registraron 150 soldados heridos en combate. Este número disminuyó a 84, 63, 32 y 6 en los años 2013, 2014, 2015 y 2016 respectivamente. La proporción de pacientes con un ISS ≥9 y la proporción de admitidos a la unidad de cuidado intensivo fueron significativamente mayores en el periodo antes de la negociación. Desde Agosto a Diciembre/2016 no se registraron admisiones. Conclusión: Este estudio describe una disminución gradual en el número de soldados heridos en combate admitidos al departamento de emergencia en un periodo de 6 años. Este fenómeno pudo deberse al periodo de negociación del proceso de paz.

Retenção de projéteis de arma de fogo na face: relato de casos / Firearms projectiles retention in the face: cases report

As agressões por arma de fogo podem trazer consequências devastadoras para a face e para a vida do indivíduo, sobretudo quando ferimentos extensos, fraturas e retenção dos projéteis estão envolvidos, podendo tornar o tratamento bem desafiador. Quando o ferimento é penetrante e os projéteis ficam alojados no organismo, adiciona-se complexidade ao quadro, pois muitas complicações podem surgir. É imprescindível que a tomada de decisão pela abordagem cirúrgica ou conservadora em relação aos objetos alojados leve em consideração critérios clínicos, cirúrgicos e anatômicos, a fim de trazer melhor qualidade de vida e menor morbidade ao paciente. Dessa forma, o objetivo deste estudo é revisar e discutir os aspectos do ferimento penetrante por Projétil de Arma de Fogo e ilustrar por meio de cinco casos clínicos, diferentes condutas em relação ao manejo desses objetos quando retidos na face... (AU)

The assaults with firearms can lead devastating consequences for the face and the life of the individual, especially when large wounds, fractures and retention of projectiles are involved, can become quite challenging treatment. When the wound is penetrating and projectiles are housed in the body, it adds complexity to the frame, since many complications can arise. It is essential that the light decision making by surgical or conservative approach to staying objects take into account clinical, surgical and anatomical criteria to bring better quality of life and less morbidity to the patient. Thus, the aim of this study is to review and discuss aspects of penetrating injury by Projectile Firearms and illustrate through five clinical cases, different conduct in relation to the management of these projectiles when retained in the face...

Isolated liver gunshot injuries: nonoperative management is feasible? / Lesão hepática isolada por arma de fogo: é possível realizar tratamento não operatório?

ABSTRACTObjective:to evaluate the safety and effectiveness of non-operative management (NOM) of liver injury, being the only abdominal injury, from gunshot wounds to the abdomen.Methods:patients who had liver damage diagnosed as single abdominal injury caused by PAF in the right thoracoabdominal region, hemodynamically stable were studied. All underwent examination with computed tomography. Were analyzed: age, gender, levels of trauma, hemodynamic condition and the abdominal examination on admission, the results of the CT scan, the extra-abdominal lesions found, the serum levels of hemoglobin, clinical course, complications, length of hospital stay, outpatient treatment and death.Results:during the study period 169 patients, treated non-operatively, presented liver gunshot wounds. Of these, only 28 patients (16.6%) had liver injury as the only abdominal injury and consequently met the inclusion criteria for this study. The average age was 27.7 years and 25 patients (89.2%) were male. The overall average of verified trauma scores were: RTS 7.45, ISS 10.9, and TRISS 98.7%. The most frequent injuries were grade II and grade III (85.7%). Complications occurred in only one patient who presented a progressive decline in hemoglobin. He underwent a CT scan which showed blush in the liver parenchyma. An arteriography was performed, which showed a successfully embolized arteriovenous fistula. There were no deaths in the patient sample. The average hospital stay was 5.3 days.Conclusion:isolated hepatic injury in gunshot abdominal trauma is uncommon. However, the NOM protocol for this type of injury is safe and has low morbidity. This approach should only be followed in institutions with adequate infrastructure, where an experienced and cohesive team is able to follow a specific protocol, with rigorous periodic evaluation of its results.

RESUMOObjetivo:analisar a segurança e efetividade do tratamento não operatório (TNO) da lesão hepática, como única lesão abdominal, em vítima de perfuração por projétil de arma de fogo (PAF) no abdome.Métodos:Foram estudados os pacientes com lesão hepática diagnosticada como única lesão abdominal provocada por PAF na região toracoabdominal direita, hemodinamicamente estáveis. Todos foram submetidos ao exame com tomografia computadorizada. Foram analisados: idade, sexo, índices de trauma, condição hemodinâmica e exame do abdome à admissão, resultados da tomografia computadorizada, lesões extra-abdominais existentes, níveis séricos de hemoglobina, evolução clínica, presença de complicações, tempo de permanência hospitalar, acompanhamento ambulatorial e óbito.Resultados:no período do estudo, 169 pacientes do protocolo de TNO apresentaram lesão hepática por projétil de arma de fogo. Destes, apenas 28 pacientes (16,6%) possuíam lesão hepática como única lesão abdominal e preencheram os critérios de inclusão no estudo. A média de idade foi 27,7 anos e 25 pacientes (89,2%) eram do sexo masculino. A média global dos índices de trauma verificada foi: RTS 7,45; ISS 10,9; e TRISS 98,7%. As lesões mais frequentes foram a grau II e grau III (85,7%). Um paciente apresentou complicação. Não houve óbito na série. A média de permanência hospitalar foi 5,3 dias.Conclusão:A lesão hepática isolada no trauma penetrante por PAF é pouco frequente e o tratamento não operatório desse tipo de lesão é seguro e apresenta baixa morbidade.

Which Graft must be Preferred in Firearm Injury of the Axillary Artery.

Aims: Interposition graft technique is used mostly in firearm wounds of axillary artery, because of excessive defect of the vessel. Autologous vein has been preferred in general application, even though there is a mild size discrepancy between native artery and autologous vein. However, in many series, prosthetic graft infection risk has been reported as low. Presentation of Case: I am presenting a patient with a gunshot wound to the right upper chest. As a first choice I preferred saphenous vein which was occluded by thrombosis at the post-repair third week in spite of anticoagulant therapy and was replaced with prosthetic graft which was patent at the eight month follow-up. Discussion: Although the theoretical risk of infection of prosthetic grafts, many previous reports have demonstrated that prosthetic grafts are nearly as safe as autologous grafts and they have high long-term patency rate. Conclusion: There is no point in insisting on autologous grafts in cases of the diameter discrepancy between native artery and autologous graft, prosthetic graft may be used more frequently in axillary artery trauma, and post-repair anticoagulants may be administered in the consequences of size discrepancy between the native artery and the graft.

Brachial index does not reflect upper extremity functionality following surgery for vascular trauma / O índice tornozelo-braço não reflete a funcionalidade da extremidade superior após cirurgia para o trauma vascular

OBJECTIVES: Vascular injuries to the upper extremities requiring surgical repair are common after accidents. However, neither postoperative functionality nor hemodynamic status of the extremity are routinely described. We evaluated the postoperative functional and hemodynamic status of patients with vascular traumas in the upper extremities. METHODS: 26 patients who suffered penetrating vascular traumas in the upper extremities from November 2008 to December 2011 were retrospectively evaluated. Data on first approach, surgical technique employed and early postoperative outcomes were recorded. Further data on the post-discharge period, including clinical functional status of the arm, Doppler ultrasonography and brachial-brachial index were also evaluated. RESULTS: Average follow up was 33.5±10.8 months. Right (1.05±0.09) and left (1.04±0.08) brachial indexes were measured during follow up,. Doppler ultrasonography showed arterial occlusion in 4 patients (15%). Near-normal brachial-brachial indexes was observed in all four of these patients with occlusion of one of the upper extremity arteries, even though they exhibited limited arm function for daily work. CONCLUSIONS: Evaluation of the postoperative outcomes of this small series of patients with penetrating vascular traumas in the upper extremity revealed that 15% of them suffered occlusion of one artery of the upper extremity. Artery occlusion did not correlate with brachial-brachial Doppler index, probably due to rich collateral circulation, but occlusion was associated with an extremity that was dysfunctional for the purposes of daily work. The result of the brachial-brachial index does not therefore correlate with functionality...

OBJETIVOS: Os vasos das extremidades superiores são frequentemente lesados em razão de acidentes. Nós pesquisamos a funcionalidade dos membros superiores com base nos resultados cirúrgicos, além do acompanhamento de lesões de outros órgãos e tecidos. MÉTODOS: Entre novembro de 2008 e dezembro de 2011, 26 pacientes foram encaminhados ao nosso serviço de emergência em razão de lesões vasculares traumáticas da extremidade superior, sendo avaliados retrospectivamente. O atendimento inicial aos pacientes, assim como os diagnósticos e as variedades de tratamento, foram avaliados. Após a alta hospitalar, os pacientes foram acompanhados pelo eco-Doppler e pelo índice tornozelo-braço. RESULTADOS: O tempo médio de seguimento foi de 33,5±10,8 meses. Durante o seguimento, os índices braquiais direito (1,05±0,09) e esquerdo (1,04±0,08) foram medidos. Na ultrassonografia Doppler, foi observada obstrução arterial em quatro pacientes. Devido à circulação colateral, o índice tornozelo-braço foi próximo do normal nesses pacientes; entretanto, eles apresentavam limitações funcionais dos membros superiores acometidos, para o trabalho diário. CONCLUSÕES: Traumas penetrantes são frequentemente observados em adultos jovens. Esses pacientes devem ser rapidamente tratados para que retornem ao seu trabalho. O planejamento do tratamento deve ser multidisciplinar, para abranger também as lesões de outros órgãos e tecidos. Nosso estudo mostrou que não há correlação entre o índice tornozelo-braço e a funcionalidade da extremidade superior, após cirurgia para o trauma vascular...

Correction of carotid-jugular traumatic fistula using a bovine pericardial patch / Correção de fístula traumática carotídeo-jugular com pericárdio bovino

Carotid-jugular fistulae are rare, but habitually cause morbidity and mortality. They are often linked with penetrating trauma, primarily caused by gunshots. This report describes the case of a patient who was the victim of a gunshot wound to the left cervical area, provoking a carotid-jugular arteriovenous fistula and occlusion of the common carotid artery. The fistula was corrected by ligature of the internal jugular vein and arteriorrhaphy of the left common carotid artery with a bovine pericardium patch.

A fístula carotídeo-jugular é de ocorrência rara, porém habitualmente causa morbimortalidade. Está associada frequentemente a trauma penetrante, principalmente em razão de lesão por projétil de arma de fogo. Relata-se o caso de um paciente vítima de lesão por projétil de arma de fogo na região cervical esquerda, o que provocou fístula arteriovenosa carotídeo-jugular com oclusão da artéria carótida comum. Foi realizada correção da fístula com ligadura da veia jugular interna e arteriorrafia com remendo de pericárdio bovino na artéria carótida comum esquerda.

Endovascular correction of a traumatic internal iliac arteriovenous fistula with a covered stent / Correção endovascular de fístula arteriovenosa traumática em ilíaca interna com stent revestido

Arteriovenous fistulae (AVFs) are anomalous communications between an artery and a vein, bypassing the capillary network. They can be subdivided on the basis of etiology into congenital and acquired fistulae. The latter may be caused by closed or penetrating traumas, or may be iatrogenic injuries. We report on a case of a young adult female gunshot wound victim treated with emergency laparotomy who developed asymmetrical edema of the lower limbs during the late postoperative period. Imaging exams showed the presence of a left internal iliac AVF, treated using endovascular surgery with placement of a covered stent, resulting in total occlusion of arteriovenous communication.

As fístulas arteriovenosas (FAVs) são comunicações anômalas entre uma artéria e uma veia, sem envolvimento capilar. Segundo sua etiologia, podem ser divididas em congênitas e adquiridas, resultantes de traumas fechados ou penetrantes, e de lesões iatrogênicas. Relatamos o caso de mulher jovem, vítima de ferimento por arma de fogo, submetida à laparotomia de urgência, que evoluiu no pós-operatório tardio com edema assimétrico de membros inferiores. Os exames de imagem demonstraram a presença de fístula arteriovenosa ilíaca interna esquerda, tratada através de cirurgia endovascular com stent revestido, determinando a total oclusão da comunicação arterial e venosa.

Retrograde venous bullet embolism after thoracic gunshot / Embolia balistica venosa retrograda apos ferimento toracico por arma de fogo

Bullet embolism is a rare complication of penetrating gunshots. We present a case of a 24-year-old man with a gunshot wound in the left scapular area, with no exit wound. Abdominal X-rays and a computed tomography (CT) scan suggested that the bullet was located within the intra-abdominal topography (intrahepatic), but laparotomy revealed no intra-abdominal injuries. After surgery, a sequential CT scan showed that the bullet had migrated to the right internal iliac vein (IIV). Venography confirmed the diagnosis of right IIV embolism and the decision was taken to attempt snare retrieval of the bullet, which was unsuccessful. It was therefore decided to leave the missile impacted inside the right IIV and the patient was put on oral anticoagulation. The patient recovered and was event free at 6 months' follow up.

Embolia balística é uma complicação rara de ferimentos por arma de fogo. Apresentamos um caso de um homem de 24 anos, vítima de um ferimento por arma de fogo em hemitórax posterior esquerdo (região escapular), sem orifício de saída. Radiografias e tomografia computadorizada do abdome evidenciaram um projétil em topografia intra-abdominal (intra-hepática); no entanto, a laparotomia exploradora demonstrou ausência de lesões intra-abdominais. Após a cirurgia, novo exame tomográfico revelou a migração da bala para a região da veia ilíaca interna (VII) direita. Realizada uma flebografia, esta confirmou a migração do projétil para a VII direita; tentou-se retirar o projétil durante o procedimento, sem sucesso. Optou-se, então, por deixá-la impactada na VII direita e manter o paciente em anticoagulação oral. O paciente evoluiu sem intercorrências até o sexto mês de seguimento.

Tratamento não operatório das lesões renais por arma de fogo / Non operative management of renal gunshot wounds

OBJETIVO: analisar a experiência do tratamento não operatório (TNO) das lesões renais ocasionadas por projétil de arma de fogo (PAF), na região tóraco-abdominal direita, em pacientes com estabilidade hemodinâmica e sem sinais de irritação peritoneal), com destaque para a avaliação da segurança desse tipo de abordagem. MÉTODOS: estudo prospectivo, em pacientes vítimas de agressão por PAF na região tóraco-abdominal direita, com lesão renal, atendidos no Hospital João XXIII (FHEMIG), em Belo Horizonte, no período de janeiro de 2005 a dezembro 2012. Os critérios de inclusão neste estudo foram: estabilidade hemodinâmica, estudo morfofuncional renal pela tomografia e ausência de sinais de irritação peritoneal. RESULTADOS: No período, 128 pacientes preencheram os critérios de inclusão do protocolo e foram submetidos à TNO de ferimento tóraco-abdominal direito por PAF. Destes, 37 (28,9%) apresentavam lesão renal. Índices de trauma: RTS 7,8; ISS 16; e TRISS 99%. As lesões grau II e grau III foram as mais frequentes. A lesão intra-abdominal associada mais comum foi a lesão hepática, presente em 81,1% dos casos. Dois pacientes (5,4%) apresentaram falha no tratamento não operatório. CONCLUSÃO: o tratamento não operatório dessas lesões renais, quando bem indicado, tem alto índice de sucesso, baixa taxa de complicações e aumenta a chance de preservação renal. Ele é seguro para pacientes bem selecionados, em centros de trauma com infraestrutura adequada, profissionais experientes e protocolo específico para realizá-lo.

OBJECTIVE: To analyze the experience of nonoperative management (NOM) of renal injuries caused by a firearm projectiles (FAP) in the right thoraco-abdominal region in patients with hemodynamic stability and no signs of peritoneal irritation, highlighting the assessment of the safety of this approach. METHODS: This was a prospective study with patients sustaining injuries by FAP in the right thoraco-abdominal region and kidney lesions, treated at the João XXIII Hospital (FHEMIG) in Belo Horizonte, from January 2005 to December 2012. Inclusion criteria were: hemodynamic stability, renal morphofunctional study by CT and no signs of peritoneal irritation. RESULTS: A total of 128 patients met the inclusion criteria of the protocol and underwent NOM for right thoraco-abdominal injury by FAP. Of these, 37 (28.9%) had renal injuries. Trauma indexes: RTS 7.8, ISS16, and TRISS 99%. Lesions grade II and grade III were the most frequent. The most commonly associated intra-abdominal injury was of the liver, present in 81.1% of cases. Two patients (5.4%) had failed nonoperative treatment. CONCLUSION: The nonoperative treatment of such renal lesions, when properly indicated, has a high success rate, low complication rate and increases the chance of renal preservation. It is safe for well-selected patients in trauma centers with adequate infrastructure, experienced professionals and use of a specific protocol.

Tratamento não operatório do ferimento por arma de fogo na região toracoabdominal direita / Non operative management of gunshot wounds on the right thoracoabdomen

OBJETIVO: Analisar os resultados obtidos com a introdução do protocolo de tratamento não operatório (TNO) dos ferimentos por arma de fogo (PAF) na transição toracoabdominal direita. MÉTODOS: Estudo prospectivo com dados levantados no período de janeiro de 2005 a dezembro de 2011, tendo como critérios de inclusão: PAF localizado na região toracoabdominal direita, estabilidade hemodinâmica, ausência de sinais de irritação peritonial e realização de tomografia computadorizada. RESULTADOS: No estudo 115 pacientes preencheram os critérios de inclusão. A maioria dos pacientes (95,6%) era do sexo masculino. A média das idades foi 25,8 anos. A média dos índices de trauma: RTS 7,7; ISS 14,8; e TRISS 97%. A maioria dos pacientes era portadora de ferimentos toracoabdominais (62,6%) e 43 pacientes (37,4%), ferimentos abdominais. A lesão hepática ocorreu em 109 pacientes (94,8%) e a renal em 28 pacientes (24,4%). Hemotórax e lesão concomitante abdominal foram verificados em 72 pacientes (62,6%). As lesões associadas foram encontradas em 19 (16,5%) pacientes e as complicações, em 12 (10,5%). A falha do TNO aconteceu em quatro pacientes (3,5%). Nesta série, dois pacientes (1,7%) morreram, ambos devido a trauma cranioencefálico. A permanência hospitalar média foi 9,4 dias. Sessenta e sete pacientes (58,3%) compareceram no controle com dois meses de trauma. A tomografia de abdome mostrou lesão cicatrizada em 58 pacientes (86,5%). CONCLUSÃO: A opção por TNO do PAF na região toracoabdominal direita deve ser vista com cautela e empregada em casos selecionados através de protocolos bem fundamentados e em locais com toda infraestrutura necessária.

OBJECTIVE: To analyze the results after the implementation of the non-operative management (NOM) of the right upper thoracoabdominal gunshot injuries protocol. METHODS: Prospective study. From January 2005 to December 2011, 115 patients were included into this study. Criteria for inclusion were gunshot wound to the right thoracoabdominal region, haemodynamic stability, no signs of peritonitis, and realized CT scan. The data collected were analysed by the software EXCEL. RESULTS: Among the 115 patients included in our study, the mean age was 25.8 years old (range, 14-78 years old), of whom 95.6% were male, 62.6% had thoracoabdominal injuries and 37.4% had exclusively abdominal injuries. The averages of trauma scores were RTS 7.7, ISS 14.8 and TRISS 97%. One hundred and nine patients (94.8%) had liver injury, 72 (62.6%) had diaphragm and lung injury, 28 (24.4%) had renal injury. Complications were present in 12 (10.5%) patients, 7 of these related to the thorax. The NOM failure happened in 4 (3.5%) patients, 2 of them due to bile peritonitis, 1 related to bleeding and 1 the laparotomy was unnecessary. The mean hospital stay was 9.4 days. There were 2 deaths due to associated gunshot brain injury. Sixty seven patients (58.3%) were presented in the follow-up after 2 months of trauma. The CT scan showed injury scar in 58 patients (86.5%). CONCLUSION: NOM of the penetrating right thoracoabdominal injuries must be seen with caution. The NOM of right thoracoabdominal gunshot injuries is safe only in selected cases, followed by well-defined protocols and when performed in places that have adequate infrastructure.

Tratamento imediato de fratura de mandíbula por projétil de arma de fogo / Immediate treatment of mandibular fracture caused by gunshot

Ferimentos por armas de fogo podem resultar em consequências estéticas e funcionais devastadoras para as vítimas desse tipo de trauma. Vários fatores influenciam este tipo de ferimento, tornando complexo o atendimento inicial e o tratamento definitivo pela imprevisibilidade destes. Durante muito tempo os cirurgiões maxilo-faciais acreditaram na necessidade de uma primeira abordagem mais conservadora limitada apenas à limpeza dos ferimentos e bloqueio maxilo-mandibular. Outras abordagens seriam realizadas caso necessário e depois do período inicial do primeiro trauma. Entretanto, a literatura contemporânea apresenta uma tendência em substituir o tratamento fechado pelo uso de tratamento aberto e fixação interna funcionalmente estável, possibilitando a reintegração do paciente à sociedade o mais rápido possível. O objetivo desse trabalho foi revisar os aspectos técnicos envolvidos no tratamento imediato nesse paciente, bem como relatar dois casos em que a conduta inicial foi o tratamento definitivo.

Gunshot wounds can result in devastating aesthetic and functional consequences for the victims of this type of trauma. Many factors influence this type of injury, making initial care and definitive treatment complex because of its unpredictability. For a long time, maxillofacial surgeons believed that a more conservative initial approach was better, limited only to the cleaning of wounds and maxillomandibular fixation. Other approaches would be performed if needed and after the initial period of the first trauma was over. However, contemporary literature shows a trend to replace closed treatment by open treatment and a functionally stable internal fixation, which allows patients to resume their normal lives as soon as possible. The objective of this work was to review the technical aspects involved in the immediate treatment of this type of patient, as well as to report two cases in which the initial conduct was the definitive treatment.

Management of gunshot injuries to the head and brain

Craniocerebral gunshot wounds are often devastating. The in-hospital mortality for civilians with penetrating craniocerebral injury is 52-95 percent depending on the proportion of suicide victims in the series. The devastating nature of this lesion is accentuated by the fact that predominantly affects young and healthy patients. The most important predictive factor is the post-resuscitation Glasgow Coma Score (GCS). Early aggressive resuscitation, surgery and vigorous control of intracranial pressure offers the best chance of achieving a satisfactory outcome. In this paper the authors performed a critical literature review about this issue and discuss the clinical aspects and management in these patients.

Tratamiento quirúrgico de las heridas cardíacas: experiencia en 23 pacientes en el Hospital Universitario de Maracaibo / Surgical treatment of hearth injuries: experience in 23 patients at the Hospital Universitario de Maracaibo

Evaluar el diagnóstico y tratamiento de las heridas cardíacas en el Hospital Universitario de Maracaibo. Se evaluaron un total de 23 pacientes quienes presentaron traumatismos cardíacos penetrantes en el período comprendido entre enero de 1991 y enero de 2007, los signos y síntomas presentes, localización de la lesión, estudios diagnósticos, intervenciones quirúrgicas realizadas y evolución postoperatoria. De los 23 traumatismos cardiovasculares penetrantes, 11 (47.82 por ciento) correspondieron a arma de fuego, 9 (39.13 por ciento) a heridas por arma blanca y 3 (13.045 por ciento) por pico de botella. Las lesiones cardíacas más frecuentes fueron: 11 heridas en ventrículo izquierdo (47.82 por ciento), 10 en ventrículo derecho (43.47 por ciento) 2 en aurícula derecha (8.69 por ciento). 2 pacientes (8,69 por ciento) presentaron choque hipovolémico durante el acto operatorio. 3 pacientes (13.04 por ciento) fallecieron en el postoperatorio inmediato y 2 (8,69 por ciento) en el postoperatorio tardío por sepsis.

Role of pre-hospital care in reducing mortality rate among victims of gunshot injuries

This study can be regarded as the first research done solely on autopsy findings in the Iraqi Kurdistan region. It is a prospective study on [106] cadavers who were victims of gunshot injuries [included those who died at the scene and those who died as in-patients] seen in Sulaimani Forensic Department from February 2003 to February 2004. A classical approach by dissection was used to determine cause of death in each victim, with age and sex incidence in order to clarify role and importance of pre-hospital care in reducing death for victims of gunshot injuries. In general, victims were either received from the scene after an average period of two to four [2-4] hours from the event or directly from the hospital. The main causes of death among those received from the scene were severe bleeding due to vascular or organic injuries [account for [53/106] 50. 02%], laceration of brain tissue [47/106] 44.34%, and spinal cord transaction [1/106] 0.94%. While septicemia is the only cause of death among those received from hospital, accounting for [5/106] 4.7%. Deaths occurred from injuries to different anatomical sites of the body: head alone [42/106] 39.62%, head with extremity [6/106] 5.66%, neck alone[1/106] 0.94%,chest alone [16/106] 15.92%, chest with extremity [8/106] 7.54%, abdomen alone [15/106] 14.15%, abdomen with extremity[4/106] 3.77%, thigh alone [11/106] 10.37%, and pelvis alone [3/106] 2.83%. The most significant finding is that life almost always could be preserved in at least [11/106] 10.37% with a single bullet injury to thigh if pre-hospital care was present. Death from gunshot injuries can be regarded as a second major cause of death after road traffic accidents in our region with sex distribution of 86.79% males and 13.21% females. The peak age incidence for females was between 14-44 years and for males 14-54 years, regardless of the type of events, i.e. criminal, suicidal or accidental. Incidence of gunshot injuries are more common in rural areas than urban ones in a ratio of 5.5:1
