Early administration of fibrinogen concentrate in patients with polytrauma with thromboelastometry suggestive of hypofibrinogenemia: A randomized feasibility trial

OBJECTIVE: To evaluate the clinical effects of early administration of fibrinogen concentrate in patients with severe trauma and hypofibrinogenemia. METHODS: We conducted an open randomized feasibility trial between December 2015 and January 2017 in patients with severe trauma admitted to the emergency department of a large trauma center. Patients presented with hypotension, tachycardia, and FIBTEM findings suggestive of hypofibrinogenemia. The intervention group received fibrinogen concentrate (50 mg/kg), and the control group did not receive early fibrinogen replacement. The primary outcome was feasibility assessed as the proportion of patients receiving the allocated treatment within 60 min after randomization. The secondary outcomes were transfusion requirements and other exploratory outcomes. Randomization was performed using sequentially numbered and sealed opaque envelopes. ClinicalTrials.gov: NCT02864875. RESULTS: Thirty-two patients were randomized (16 in each group). All patients received the allocated treatment within 60 min after randomization (100%, 95% confidence interval, 86.7%-100%). The median length of intensive care unit stay was shorter in the intervention group (8 days, interquartile range [IQR] 5.75-10.0 vs. 11 days, IQR 8.5-16.0; p=0.02). There was no difference between the groups in other clinical outcomes. No adverse effects related to treatment were recorded in either group. CONCLUSION: Early fibrinogen replacement with fibrinogen concentrate was feasible. Larger trials are required to properly evaluate clinical outcomes.

Factor tiempo en la atención inicial del paciente politraumatizado / Factor time in the initial attention of the poly-traumatized patient

RESUMEN Introducción: el politraumatismo por si solo constituye uno de los problemas más grandes de la sociedad moderna. Las lesiones traumáticas en Cuba aparecen en el quinto lugar entre las causas globales de muerte para todas las edades. Objetivo: determinar cómo incidió el factor tiempo en la organización de las acciones para la atención de urgencia al paciente politraumatizado. Materiales y método: se realizó un estudio observacional, conformado por 183 pacientes politraumatizados, atendidos en la Unidad de Cuidados Intensivos Emergentes del Hospital Provincial". José R. López Tabrane " de Matanzas, durante el año 2014. Las variables a considerar fueron: edad, sexo, tiempo en que recibieron las primeras acciones, tiempo de llegada al Hospital, factores asociados que influyeron en la aparición de injuria secundaria. Se utilizó la técnica estadística de análisis de distribución de frecuencias. Resultados: el mayor porcentaje de los pacientes (82,6 %) acudieron 4-6 h después de sufrido el traumatismo. Aparecieron factores como la hipotensión, la hipoxia (66,1 y 50,2 %) respectivamente, que tuvieron lesiones asociadas y fueron valoradas en la primera hora del traumatismo. Conclusiones: el trauma severo es una de las entidades prevenibles que más vida cobra en la sociedad. El sexo masculino y edades más productivas de la vida fueron los que más morbimortalidad presentaron. El hecho de que la mayor cantidad de estos pacientes arribaron al Hospital después de la hora dorada, propició un mayor número de complicaciones por el no control a tiempo de los elementos que forman la injuria secundaria (AU).

ABSTRACT Introduction: polytrauma, by itself, is one of the biggest problems of the modern society. Trauma lesions in Cuba are in the fifth place among the death global causes for all age groups. Objective: to determine how time factor had an impact in the actions organization for the emergency care to polytrauma patient. Materials and method: an observational study was performed in 183 poly-trauma patients who attended the Intensive Care Unit of the Provincial Hospital "Jose Ramón López Tabrane" of Matanzas during 2014. The considered variables were: age; sex; time of receiving the first actions; time of arrival to the hospital; associated factors influencing in the appearance of secondary injury. The authors used the statistic technique of analysis of frequency distribution. Results: the highest percent of patients (82.6 %) assisted the consultation 4-6 hours after suffering the trauma. There were found factors like hypotension and hypoxia (66.1 and 50.2 % respectively that had associated lesions and were assessed in the first hour of the trauma. Conclusions: acute trauma is one of the preventable entities taking more lives in the society. Male sex predominated and the more productive ages of life were the ones presenting more morbid-mortality. The fact that the biggest quantity of these patients arrived to the hospital after the golden hour favored a higher number of complications due to the untimely control of the elements forming the secondary injury (AU).

Implementation of a new Single-Pass Whole-Body Computed Tomography Protocol: Is it safe, effective and efficient in patients with severe trauma? / Implementación de un nuevo protocolo de Tomografía Computarizada Corporal Total de un solo pase: ¿Es seguro, efectivo y eficiente en pacientes con trauma severo?

Abstract 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.

Resumen 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.

A temporary-sustainable team: A new multidisciplinary team model for severe trauma / 中华创伤杂志(英文版)

The treatment of severe trauma, especially multiple injuries, requires multidisciplinary collaboration. The current study aims to highlight the challenges of consultation mode for severe trauma in general hospitals and emphasizes the need to create a new temporary-sustainable team. It suggests developing an information consultation mode and enforcing the fine management to improve the quality and safety of the medical treatment. The management mode of a temporary-sustainable team will reduce the cost and improve the treatment efficiency. Overall, a temporary-sustainable team has significant advantages over a traditional multidisciplinary team for severe trauma treatment.

Perfil epidemiológico de crianças de 0-18 anos vítimas de queimaduras atendidas no Serviço de Cirurgia Plástica e Queimados de um Hospital Universitário no Sul do Brasil / Epidemiological profile of 0­18-year-old child victims of burns treated at the Plastic Surgery and Burns Service of a University Hospital in Southern Brazil

Introdução: Lesões geradas por queimaduras representam um importante problema de saúde pública, constituindo a quarta causa de morte na infância no Brasil e Estados Unidos. Além disso, poucas são as doenças que trazem prejuízos tão importantes, com considerável morbidade pelo desenvolvimento de sequelas físicas e psicossociais. Diante disso, o objetivo deste estudo é traçar o perfil epidemiológico de crianças de 0-18 anos atendidas em um hospital escola de Curitiba, Paraná. Métodos: Estudo transversal e retrospectivo realizado através da análise de 625 prontuários de internação de crianças de 0-18 anos vítimas de queimaduras, entre janeiro de 2010 a dezembro de 2017. Foram coletadas informações sobre idade, sexo, tempo de internação, óbito, região corporal atingida, extensão da superfície corporal, grau de profundidade, agente etiológico e abordagem terapêutica. Resultados: A maior parte da amostra era composta por lactentes (43%), com média de idade de 12,6 anos. O sexo mais afetado foi o masculino e os pacientes permaneceram cerca de 14,5 dias internados. No estudo, 98% das queimaduras apresentaram como etiologia o agente térmico, principalmente por líquido quente. Em relação ao grau de profundidade, a maioria das queimaduras foram de 2º grau (61,3%), atingindo até 25% de superfície corporal queimada (SCQ), sendo o tronco o mais afetado. Dentre as modalidades de tratamento, 44% dos pacientes necessitaram de intervenção cirúrgica com debridamento e enxertia. Conclusão: Crianças mais novas são mais propensas a sofrerem queimaduras principalmente no ambiente domiciliar e, além disso, uma equipe preparada e capacitada é de crucial importância no prognóstico destes doentes.

Introduction: Injuries caused by burns represent a significant public health problem, constituting the fourth leading cause of childhood death in Brazil and the United States. In addition, few diseases carry such substantial losses as burns, with considerable morbidity due to the development of physical and psychosocial sequelae. This study aimed to outline the epidemiological profile of 0­18-year-old children treated for burns at a teaching hospital in Curitiba, Paraná. Methods: This cross-sectional, retrospective study involved analysis of 625 medical records of 0­18-year-old children who were victims of burns from January 2010 to December 2017. Information was collected on age, sex, length of hospitalization, death, body region affected, burned body surface area (BSA), depth, etiologic agent, and therapeutic approach. Results: A plurality of the sample were infants (43%), and the average age of the sample was 12.6 years. Most of the sample was comprised males, and the patients remained hospitalized for an average of 14.5 days. Of the burns, 98% were caused by thermal agents, particularly hot liquids. Most burns were second-degree burns (61.3%), reaching up to 25% of the BSA, and the most affected region was the trunk. Among the treatment modalities, 44% of the patients needed surgical intervention with debridement and grafting. Conclusion: Younger children are more prone to burns, especially in the home environment. A prepared and qualified team is of crucial importance for optimizing outcomes in these patients.

Hemocomponentes en urgencias: tratamiento vital para los pacientes politraumatizados / Blood products in the emergency room: vital treatment for polytraumatized patients

Introducción: La principal causa de mortalidad temprana en pacientes politraumatizados es la hipovolemia secundaria a hemorragia masiva. La terapia con hemocomponentes y cristaloides constituye un mecanismo esencial y salvavidas en estas situaciones como medida de reemplazo de volumen. De la misma manera los pacientes con lesiones traumáticas graves tienen una disminución aguda significativa en el recuento de plaquetas circulantes que los hace candidatos a la transfusión de componentes plaquetarios; sin embargo, el uso de estos componentes sanguíneos puede traer consigo desenlaces no deseados como aumento en la mortalidad. Si bien muchos estudios revelan un aumento de la mortalidad como desenlace asociado al uso de hemocomponentes, otros establecen su uso como una medida reductora de este desenlace. Objetivo: Exponer las principales indicaciones de hemocomponentes en los pacientes politraumatizados, así como relacionar los eventos adversos asociados a su uso que influyen sobre la mortalidad y el tiempo de hospitalización de estos pacientes. Desarrollo: La mortalidad asociada al uso de hemocomponentes aún es un tema controvertido. En la hemorragia masiva el apoyo transfusional rápido y eficiente es esencial en el tratamiento y la atención de politraumatismos, de ahí que sea necesario contar con protocolos de transfusión que mejoren los resultados y disminuyan las complicaciones. Además, se identificó la necesidad de nuevos estudios sobre el tema para mejorar estos protocolos y reducir las complicaciones.(AU)

Introduction: The main cause of early mortality in polytrauma patients is hypovolemia secondary to massive hemorrhage. Hemocomponent and crystalloid therapy is an essential and life-saving mechanism in these situations as a measure of volume replacement. In the same way, patients with severe traumatic injuries have a significant acute decrease in circulating platelet counts that makes them candidates for transfusion of platelet components; However, the use of these blood components can lead to unwanted outcomes such as increased mortality. Although many studies reveal an increase in mortality as an outcome associated with the use of blood components, others establish its use as a reducing measure of this outcome. Objective: to present the main indications of blood components in polytrauma patients, as well as to relate the adverse events associated with their use that influence the mortality and hospitalization time of these patients. Devlopment: Mortality associated with the use of blood components is still a controversial issue. In massive hemorrhage, rapid and efficient transfusion support is essential in the treatment and care of polytrauma, hence it is necessary to have transfusion protocols that improve results and reduce complications. In addition, the need for new studies on the subject to improve these protocols and reduce complications was identified(AU)

Trauma e transfusão sanguínea precoce: o desafiante manejo de hemorragias em Testemunhas de Jeová / Trauma and early blood transfusion: the challenging hemorrhage management in Jehovah's Witnesses

RESUMO O manejo de pacientes que se recusam a receber transfusões de sangue e de seus produtos, como as Testemunhas de Jeová, apresenta-se frequentemente como desafio médico, não só pelo dilema ético, mas porque cria um importante obstáculo ao rápido controle de hemorragias num cenário de trauma. Este artigo explora as razões deste conflito entre o dever de cuidado do médico e o respeito à autonomia do paciente, e desenha um panorama dos entendimentos majoritários do Judiciário sobre o tema. Por fim, conclui-se que a manifestação de vontade do paciente, embora livre, não é suficiente para afastar o médico do seu dever de cuidado. Constatando perigo à vida, o médico deverá proceder a transfusão de sangue, independentemente de consentimento do paciente ou de seus responsáveis.

ABSTRACT The management of patients, such as Jehovah's Witnesses, who refuse to receive blood transfusions, is often a medical challenge, not only because of the ethical dilemma, but also because it creates a major obstacle to rapid hemorrhage control in a setting of trauma. This article explores the reasons for this conflict between the physician's duty of care and the respect for the patient's autonomy, and draws a panorama of the main understandings of the Judiciary on the subject. Finally, it is concluded that the manifestation of the patient's will, although free, is not enough to release the doctor from his (her) duty of care. In case of danger to life, the doctor must carry out a blood transfusion, regardless of the patient's consent or the permission of those responsible for the patient.

Independent early predictors of mortality in polytrauma patients: a prospective, observational, longitudinal study

OBJECTIVES: Trauma is an important public health issue and associated with substantial socioeconomic impacts and major adverse clinical outcomes. No single study has previously investigated the predictors of mortality across all stages of care (pre-hospital, emergency room, surgical center and intensive care unit) in a general trauma population. This study was designed to identify early predictors of mortality in severely injured polytrauma patients across all stages of care to provide a better understanding of the physiologic changes and mechanisms by which to improve care in this population. METHODS: A longitudinal, prospective, observational study was conducted between 2010 and 2013 in São Paulo, Brazil. Patients submitted to high-energy trauma were included. Exclusion criteria were as follows: injury severity score <16, <18 years old or insufficient data. Clinical and laboratory data were collected at four time points: pre-hospital, emergency room, and 3 and 24 hours after hospital admission. The primary outcome assessed was mortality within 30 days. Data were analyzed using tests of association as appropriate, nonparametric analysis of variance and generalized estimating equation analysis (p<0.05). ClinicalTrials.gov: NCT01669577. RESULTS: Two hundred patients were included. Independent early predictors of mortality were as follows: arterial hemoglobin oxygen saturation (p<0.001), diastolic blood pressure (p<0.001), lactate level (p<0.001), Glasgow Coma Scale score (p<0.001), infused crystalloid volume (p<0.015) and presence of traumatic brain injury (p<0.001). CONCLUSION: Our results suggest that arterial hemoglobin oxygen saturation, diastolic blood pressure, lactate level, Glasgow Coma Scale, infused crystalloid volume and presence of traumatic brain injury are independent early mortality predictors.

Atención del dolor en el paciente politraumatizado en el Hospital Militar Central "Dr. Carlos J. Finlay" / Pain management in the multi-trauma patient in ¨Dr Carlos J. Finlay¨ central military hospital

INTRODUCCIÓN: los traumatismos se han relacionado siempre con el dolor como síntoma acompañante que influye negativamente en la evolución del paciente. OBJETIVO: valorar la atención a los pacientes politraumatizados en lo referente a la evaluación y tratamiento del dolor. MÉTODO: se realizó un estudio observacional, retrospectivo, de corte transversal, de enero a diciembre de 2013, en una muestra de 60 pacientes que ingresaron con diagnóstico de politrauma, en el Hospital Militar Central "Dr. Carlos J. Finlay". Se emplearon como descriptores estadísticos medidas de resumen de los datos cualitativos (razones y proporciones). RESULTADOS: el 83,3 % de los pacientes refirió dolor al menos una vez durante el ingreso; en 51,7 % se le evaluó el síntoma, utilizando la escala verbal simple en el 26,7 %; en el resto no se usó ninguna escala. Los antinflamatorios no esteroideos se indicaron en todos los casos, con gran variabilidad en relación a las dosificaciones e intervalos de administración. Fue escasa el uso de opioides (6,7 %), ketamina (3,4 %), anestésicos locales (3,4 %) y coadyuvantes (1,7 %). Prevaleció la indicación a demanda, administrándose la analgesia en este grupo en el 46,7 %. No se evaluó la reducción del dolor en el 50 % de los casos en que se administró la analgesia, constatándose su reducción solo en el 42,9 %. En el 91,7 % de la muestra se valoró el tratamiento como inadecuado. CONCLUSIONES: la evaluación y el tratamiento analgésico son inadecuados, confirmando la necesidad de implementar estrategias para mejorar el control del dolor en el trauma.

INTRODUCTION: trauma has been related always with pain as an accompanist symptom that affects negatively the evolution of the patient. This work aspire to value the attention to polytrauma patient refers to evaluation and treatment of the pain. METHODS: an observational, retrospective, transversal study was made, since January until December of 2013. The sample was 60 patients received in "Dr. Carlos J. Finlay" Military Central Hospital with polytrauma. Stadistics measures descriptors were employed (reasons and proportions). RESULTS: the 83.3 % of the patients reports pain, at least one time during the intern; only 56.0 % of these were evaluated; in 51.7 % of the sample were evaluated the symptom; in 26.7 % of the sample was used a verbal scale; the rest of the patients were no evaluated. In all of cases were used non-steroids anti-inflammatory drugs, with doses and administration intervals vary. The use of opioids (6.7 %), ketamina (3.4 %), local anesthesics (3.4 %) and support drugs (1.7 %) were poor. Prevail the demand indication (88.3 %), using indicate analgesia in 46.7 % of the sample. The reduction of pain was evaluated in 50.0 % of cases that received analgesia; verify it only in 42.9 % of patients. In 91.7 % of the sample was valued the treatment as inadecuated. CONCLUTIONS: the evaluation and treatment of pain is deficient, confirm the necessity of implement strategies of properties actuations.

Reanimación con fluidos y hemoderivados en trauma / Resuscitation with fluids and blood products in trauma

The leading cause of preventable death in trauma is uncontrolled bleeding. Some of these deaths may be secondary to the Acute Coagulopathy of Trauma, which is present in 30% of patients on admission to hospital. In recent years, Damage Control Resuscitation has been developed, which aims to give a hemostatic resuscitation and avoid deaths caused by bleeding. This strategy considers control of bleeding with damage control surgery or interventional procedures, early transfusion of all blood products, permissive hypotension and limited use of crystalloids. Several studies have reported that early transfusion of all blood products, with a ratio close to 1:1, may be associated with lower mortality and less requirements of total transfusions in trauma patients at risk of massive bleeding and massive transfusion. These findings must be corroborated in randomized controlled trials, along with determining the optimum ratio between blood products. In stable patients, a restrictive transfusion strategy is safe and appropriate.

Manejo inicial del politraumatizado / Initial management of politraumatized patient

Trauma is today the first cause of death in young population; Motor vehicle crashes (MVC’s) are the main specific cause. The initial approach of the trauma patient takes place in the prehospital and hospital environment, following a systematic evaluation and priorizing some systems above others. Primary evaluation (with the classic sequence: ABCDE), sets intervention priorities that ultimately target a reduction in trauma early mortality. The in-corporation of ultrasonography in the evaluation of the trauma patient, has been fundamental in searching for injuries that may have been overlooked in the primary evaluation. Injuries that compromise ventilation may cause hypoxemia and hemodynamic instability. Early bleed control is the main therapeutic target in the trauma patient with active hemorrhage, which leads to reduction of early mortality and also prevents future complications. Fluid resuscitation is the main intervention to restore tissue perfusion. Also, the use of transfusional therapy, permissive hypotension and tranexamic acid must also be considered. Emergency Ultrasound is today a fundamental instrument in the initial trauma patient evaluation, because it greatly contributes to the evaluation of ventilatory derangement and hemodynamic instability causes. Finally, one must remember that trauma is a dynamic process, and therefore reevaluating is imperative, especially because findings of neurological deficit or deterioration in time, will ultimately conduct to the diagnose of injuries that cause brain hypoperfusion...

Terapia nutricional precoce no trauma: após o A, B, C, D, E, a importância do F (FEED) / Early nutritional therapy in trauma: after A, B, C, D, E, the importance of the F (FEED)

Um número significativo de mortes no trauma ocorre dias a semanas após a injúria inicial, sendo causado por infecções e insuficiência orgânica, relacionadas a hipercatabolismo e consequente desnutrição proteica aguda. A terapia nutricional deve ser planejada e incluída com as demais condutas de reanimação para pacientes politraumatizados e grandes queimados. A rápida aquisição de uma via para suporte nutricional é importante para inicio da terapia nutricional precoce em até 48 horas do atendimento. A via enteral é a opção preferencial no pós-operatório de pacientes traumatizado mas a via parenteral deve ser prescrita quando a enteral está contraindicada ou insuficiente. Após as medidas iniciais ditadas pelo ATLS, sintetizadas em A (air), B (breath), C (circulation), D (disability) e E (exposure), nós incluímos a letra F (feed) para enfatizar a importância do atendimento nutricional precoce no trauma.

A significant number of deaths in trauma occurs days to weeks after the initial injury, being caused by infection and organ failure related to hypercatabolism and consequent acute protein malnutrition. Nutritional therapy should be planned and included with other routines of resuscitation for patients with multiple trauma and severe burns. The rapid acquisition of a route for nutritional support is important to start early nutritional therapy within 48 hours of care. The enteral route is the preferred option in traumatized postoperative patients but the parenteral route should be prescribed when enteral feeding is contraindicated or inadequate. After the initial measures dictated by ATLS, synthesized in the A (airway), B (breathing), C (circulation), D (disability) and E (exposure), we include the letter F (feed) to emphasize the importance of early nutritional care in trauma.

Implante profilático e temporário de filtro de veia cava inferior no trauma / Prophylactic and temporary inferior vena cava filter implant in trauma

O tromboembolismo pulmonar (TEP) é importante causa de óbito no trauma e esse, na maioria das vezes, contraindica a principal farmacoterapia na prevenção e no tratamento do TEP: a anticoagulação. Relatamos um caso de paciente politraumatizado, com risco elevado de embolia pulmonar, submetido ao implante preventivo e temporário de filtro de veia cava inferior (FVC).

Pulmonary embolism (PE) is a major cause of death in trauma and that, on most cases, the main contraindication for pharmacotherapy in the prevention and treatment of PE: the anticoagulation. We report a case of multiple trauma patient at high risk of pulmonary embolism, preventive and implant subjected to temporary inferior vena cava filter (VCF).

Injúria Renal Aguda no paciente politraumatizado / Acute Renal Injury in polytrauma patients

A Injúria Renal Aguda (IRA) no contexto do paciente politraumatizado ocorre, na maioria das vezes, por uma conjuntura de fatores que passam por eventos correlacionados à ressuscitação volêmica inicial, ao grau de resposta inflamatória sistêmica associada ao trauma, ao uso de contraste iodado para procedimentos diagnósticos, à rabdomiólise e à síndrome compartimental abdominal. Atualmente, passamos por uma fase de uniformização dos critérios diagnósticos da IRA com o Acute Kidney Injury Network (AKIN), sendo a referência mais aceita. Consequentemente, o estudo da IRA no politraumatismo também passa por uma fase de reformulação. Esta revisão da literatura médica visa trazer dados epidemiológicos, fisiológicos e de implicação clínica para o manuseio destes pacientes, bem como expor os riscos do uso indiscriminado de expansores volêmicos e particularidades sobre a instituição de terapia renal substitutiva em indivíduos sob risco de hipertensão intracraniana.

Acute Kidney Injury (AKI) in trauma is, in most cases, multifactorial. Factors related to the initial ressuscitation protocol, degree of the systemic inflamatory response to trauma, contrast nephropathy in diagnostic procedures, rhabdomyolysis and abdominal compartment syndrome are some of those factors. Nowadays a uniformization in diagnostic criteria for AKI has been proposed by the Acute Kidney Injury Network (AKIN) and as a result the incidence of AKI and its impact in outcomes in trauma patients also needs to be reconsider. In this review we aim to approach epidemiologic, physiologic and clinical relevant data in the critical care of patients victims of trauma and also to expose the risks of indiscriminate use of volume expanders and the interaction between renal replacement theraphy and intracranial hypertension.

Ressuscitação no trauma / Trauma resuscitation

Este texto aborda a avaliação inicial e o manejo sistematizado da criança vítima de trauma, assim comoas particularidades da ressuscitação no trauma crânio-encefálico.

This paper discusses the initial assessment and systematic management of the pediatric trauma victim,as well as the peculiarities of resuscitation of head injured children.

Shock hemorrágico / Hemorrhagic shock

El shock hemorrágico es la principal causa de muerte en el trauma, la principal causa de muertes potencialmente prevenible y una de las principales causas de muerte en la población menor de 44 años. La hemorragia masiva puede producir inestabilidad hemodinámica, disminución de la perfusión tisular, daño de órganos y muerte. Los principales objetivos de la resucitación son restaurar el volumen sanguíneo circulante y detener la hemorragia, mientras se activan los protocolos de manejo de la hemorragia masiva. Si bien el método óptimo de resucitación no ha sido claramente establecido, el uso de fluidos intravenosos y productos sanguíneos son elementos esenciales del manejo. Los defectos hemostáticos son frecuentes en la hemorragia masiva y evolucionan rápidamente. Se recomienda el uso precoz de plasma fresco congelado y plaquetas para prevenir el mecanismo dilucional de la coagulopatía, y el manejo agresivo de ésta una vez establecida. Finalmente, el manejo posterior a la emergencia incluye los cuidados intensivos para una monitorización estricta y el manejo de las eventuales complicaciones sistémicas, como la falla multiorgánica.

Hemorrhagic shock is the leading cause of death after injury, the major cause of potentially preventable deaths and one of the leading cause of death in young people. Massive hemorrhage may lead to hemodynamic instability, decreased tissue perfusion, organ damage, and death. The main goals of resuscitation are to restore circulating blood volume and to stop the source of hemorrhage, while the major hemorrhage protocols must be immediately declare. Although the optimal method of resuscitation has not been clearly established, the use of intravenous fluids and blood products are the key aspects of the management. The haemostatic defects are common in massive hemorrhage and trauma, and are likely to evolve rapidly. The early use of fresh frozen plasma and platelets is recommended to prevent the dilutional mechanism, and if the haemosthatic defect is established, it should be aggressively treated. Finally, further management includes intensive therapy to closely monitoring and management of any systemic complications, as multiorganic organ damage.

Perfil da vítima atendida pelo serviço pré-hospitalar aéreo de Pernambuco / The profile of victims attended by the Pernambuco prehospital air service / Perfil de la víctima atendida por el servicio prehospitalario aéreo de Pernambuco

Estudo do tipo descritivo-exploratório com abordagem quantitativa sobre o perfil da vítima atendida pelo serviço pré-hospitalar aéreo de Pernambuco. As ocorrências foram avaliadas no período de agosto de 2007 a julho de 2008, correspondentes ao primeiro ano de funcionamento do hangar no Recife. Nesse período, foram estudados 283 fichas de ocorrências, com média de 23 atendimentos mensais. Dos vôos, 66 por cento foram de resgate, com 11 minutos de tempo-resposta. Quanto à causa do atendimento, 79 por cento foram por causas externas, na sua maioria de acidentes de trânsito. Prevaleceu o sexo masculino com faixa etária mediana de 34 anos. O resgate dessas vítimas graves deve ser realizado de forma rápida e eficaz, por isso analisou-se a relação da gravidade da vítima com o tempo-resposta.

This descriptive, exploratory study was performed using a quantitative approach to address the profile of victims attended by the Pernambuco prehospital air service. The events were evaluated from August 2007 to July 2008, corresponding to the first year of the hangar working in Recife. In the studied period, 283 event forms were studied, with an average 23 events per month. Regarding the flights, 66 percent were rescue flights with an answer-time of 11 minutes. As for the causes, 79 percent were external, mainly traffic accidents. Most victims were male, with a median age range of 34 years. The rescue of severe cases should be fast and effective, thus this study analyzed the association between the severity of a victim and the answer-time.
