Management of bleeding following major trauma: a European guideline

INTRODUCTION Evidence-based recommendations can be made with respect to many aspects of the acute management of the bleeding trauma patient, which when implemented may lead to improved patient outcomes. METHODS The multidisciplinary Task Force for Advanced Bleeding Care in Trauma was formed in 2005 with the aim of developing guidelines for the management of bleeding following severe injury. Recommendations were formulated using a nominal group process and the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) hierarchy of evidence and were based on a systematic review of published literature. RESULTS Key recommendations include the following: The time elapsed between injury and operation should be minimised for patients in need of urgent surgical bleeding control, and patients presenting with haemorrhagic shock and an identified source of bleeding should undergo immediate surgical bleeding control unless initial resuscitation measures are successful. A damage control surgical approach is essential in the severely injured patient. Pelvic ring disruptions should be closed and stabilised, followed by appropriate angiographic embolisation or surgical bleeding control, including packing. Patients presenting with haemorrhagic shock and an unidentified source of bleeding should undergo immediate further assessment as appropriate using focused sonography, computed tomography, serum lactate, and/or base deficit measurements. This guideline also reviews appropriate physiological targets and suggested use and dosing of blood products, pharmacological agents, and coagulation factor replacement in the bleeding trauma patient. CONCLUSION A multidisciplinary approach to the management of the bleeding trauma patient will help create circumstances in which optimal care can be provided. By their very nature, these guidelines reflect the current state-of-the-art and will need to be updated and revised as important new evidence becomes available.

Reseccion intestinal masiva. Proceso de adaptacion nutricional

INTRODUCTION Massive small bowel resection (MSBR) with a remnant jejunum shorter than 60 cm produces severe water, electrolytes, vitamins and protein-caloric depletion. While waiting for a viable intestinal transplantation, most of MSBR patients depend on total parenteral nutrition (TPN). CLINICAL CASE 32 years old male, with MSBR due to sectioning trauma of the superior mesenteric artery root. First surgical intervention: jejunostomy with small bowel, right colon, and spleen resection. Six months later: jejunocolic anastomosis with 12-cm long jejunum remnant and prophylactic cholecystectomy. NUTRITIONAL INTERVENTION: 1st phase. Hemodynamic stabilization and enteral stimulation (6 months): TPN + enteral nutrition with elemental formula + oral glucohydroelectrolitic solution (OGHS) + 15 g/d of oral glutamine + omeprazol. Clinical course indicators: biochemistry, I/L balance. 2a phase. Digestive adaptation with colonic integration (8 months): replacement of TPN by part-time peripheral PN. Progressive cooked diet complemented with pancreatic poly-enzyme preparation, omeprazol, OGHS, glutamine, elemental formula. Clinical course indicators: biochemistry, diuresis, weight and feces. 3a phase. Auto-sufficiency without parenteral dependence: fragmented free oral diet supplemented with pancreatic poly-enzyme preparation, mineralized beverages, enteral formula supplement, Ca and Mg oral supplements, oral multivitamin and mineral preparation, monthly IM vitamin B12. Current situation actual (52 months): slight ponderal gain, diuresis > liter/day, 2-3 normal feces, no clinical signs of any deficiency and normal blood levels of micronutrients. CONCLUSION It may be possible to withdraw from PN in MSBR considering, as in this case, favorable age and etiology and early implementation of an appropriate protocol of remnant adaptation.

The BRAIN TRIAL: a randomised, placebo controlled trial of a Bradykinin B2 receptor antagonist (Anatibant) in patients with traumatic brain injury

BACKGROUND Cerebral oedema is associated with significant neurological damage in patients with traumatic brain injury. Bradykinin is an inflammatory mediator that may contribute to cerebral oedema by increasing the permeability of the blood-brain barrier. We evaluated the safety and effectiveness of the non-peptide bradykinin B2 receptor antagonist Anatibant in the treatment of patients with traumatic brain injury. During the course of the trial, funding was withdrawn by the sponsor. METHODS Adults with traumatic brain injury and a Glasgow Coma Scale score of 12 or less, who had a CT scan showing an intracranial abnormality consistent with trauma, and were within eight hours of their injury were randomly allocated to low, medium or high dose Anatibant or to placebo. Outcomes were Serious Adverse Events (SAE), mortality 15 days following injury and in-hospital morbidity assessed by the Glasgow Coma Scale (GCS), the Disability Rating Scale (DRS) and a modified version of the Oxford Handicap Scale (HIREOS). RESULTS 228 patients out of a planned sample size of 400 patients were randomised. The risk of experiencing one or more SAEs was 26.4% (43/163) in the combined Anatibant treated group, compared to 19.3% (11/57) in the placebo group (relative risk = 1.37; 95% CI 0.76 to 2.46). All cause mortality in the Anatibant treated group was 19% and in the placebo group 15.8% (relative risk 1.20, 95% CI 0.61 to 2.36). The mean GCS at discharge was 12.48 in the Anatibant treated group and 13.0 in the placebo group. Mean DRS was 11.18 Anatibant versus 9.73 placebo, and mean HIREOS was 3.94 Anatibant versus 3.54 placebo. The differences between the mean levels for GCS, DRS and HIREOS in the Anatibant and placebo groups, when adjusted for baseline GCS, showed a non-significant trend for worse outcomes in all three measures. CONCLUSION This trial did not reach the planned sample size of 400 patients and consequently, the study power to detect an increase in the risk of serious adverse events was reduced. This trial provides no reliable evidence of benefit or harm and a larger trial would be needed to establish safety and effectiveness. TRIAL REGISTRATION This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN23625128.

Cerebral perfusion pressure and risk of brain hypoxia in severe head injury: a prospective observational study

INTRODUCTION Higher and lower cerebral perfusion pressure (CPP) thresholds have been proposed to improve brain tissue oxygen pressure (PtiO2) and outcome. We study the distribution of hypoxic PtiO2 samples at different CPP thresholds, using prospective multimodality monitoring in patients with severe traumatic brain injury. METHODS This is a prospective observational study of 22 severely head injured patients admitted to a neurosurgical critical care unit from whom multimodality data was collected during standard management directed at improving intracranial pressure, CPP and PtiO2. Local PtiO2 was continuously measured in uninjured areas and snapshot samples were collected hourly and analyzed in relation to simultaneous CPP. Other variables that influence tissue oxygen availability, mainly arterial oxygen saturation, end tidal carbon dioxide, body temperature and effective hemoglobin, were also monitored to keep them stable in order to avoid non-ischemic hypoxia. RESULTS Our main results indicate that half of PtiO2 samples were at risk of hypoxia (defined by a PtiO2 equal to or less than 15 mmHg) when CPP was below 60 mmHg, and that this percentage decreased to 25% and 10% when CPP was between 60 and 70 mmHg and above 70 mmHg, respectively (p < 0.01). CONCLUSION Our study indicates that the risk of brain tissue hypoxia in severely head injured patients could be really high when CPP is below the normally recommended threshold of 60 mmHg, is still elevated when CPP is slightly over it, but decreases at CPP values above it.

Management of bleeding and coagulopathy following major trauma: an updated European guideline.

INTRODUCTION: Evidence-based recommendations are needed to guide the acute management of the bleeding trauma patient. When these recommendations are implemented patient outcomes may be improved. METHODS: The multidisciplinary Task Force for Advanced Bleeding Care in Trauma was formed in 2005 with the aim of developing a guideline for the management of bleeding following severe injury. This document represents an updated version of the guideline published by the group in 2007 and updated in 2010. Recommendations were formulated using a nominal group process, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) hierarchy of evidence and based on a systematic review of published literature. RESULTS: Key changes encompassed in this version of the guideline include new recommendations on the appropriate use of vasopressors and inotropic agents, and reflect an awareness of the growing number of patients in the population at large treated with antiplatelet agents and/or oral anticoagulants. The current guideline also includes recommendations and a discussion of thromboprophylactic strategies for all patients following traumatic injury. The most significant addition is a new section that discusses the need for every institution to develop, implement and adhere to an evidence-based clinical protocol to manage traumatically injured patients. The remaining recommendations have been re-evaluated and graded based on literature published since the last edition of the guideline. Consideration was also given to changes in clinical practice that have taken place during this time period as a result of both new evidence and changes in the general availability of relevant agents and technologies. CONCLUSIONS: A comprehensive, multidisciplinary approach to trauma care and mechanisms with which to ensure that established protocols are consistently implemented will ensure a uniform and high standard of care across Europe and beyond.

Effectiveness of holistic neuropsychological rehabilitation for Spanish population with acquired brain injury measured using Rasch analysis.

INTRODUCTION The Rasch model is increasingly used in the field of rehabilitation because it improves the accuracy of measurements of patient status and their changes after therapy. OBJECTIVE To determine the long-term effectiveness of a holistic neuropsychological rehabilitation program for Spanish outpatients with acquired brain injury (ABI) using Rasch analysis. METHODS Eighteen patients (ten with long evolution - patients who started the program > 6 months after ABI- and eight with short evolution) and their relatives attended the program for 6 months. Patients' and relatives' answers to the European Brain Injury Questionnaire and the Frontal Systems Behavior Scale at 3 time points (pre-intervention. post-intervention and 12 month follow-up) were transformed into linear measures called logits. RESULTS The linear measures revealed significant improvements with large effects at the follow-up assessment on cognitive and executive functioning, social and emotional self-regulation, apathy and mood. At follow-up, the short evolution group achieved greater improvements in mood and cognitive functioning than the long evolution patients. CONCLUSIONS The program showed long-term effectiveness for most of the variables, and it was more effective for mood and cognitive functioning when patients were treated early. Relatives played a key role in the effectiveness of the rehabilitation program.

The STOP the Bleeding Campaign.

According to the World Health Organization, traumatic injuries worldwide are responsible for over 5 million deaths annually. Post-traumatic bleeding caused by traumatic injury-associated coagulopathy is the leading cause of potentially preventable death among trauma patients. Despite these facts, awareness of this problem is insufficient and treatment options are often unclear. The STOP the Bleeding Campaign therefore aims to increase awareness of the phenomenon of post-traumatic coagulopathy and its appropriate management by publishing European guidelines for the management of the bleeding trauma patient, by promoting and monitoring the implementation of these guidelines and by preparing promotional and educational material, organising activities and developing health quality management tools. The campaign aims to reduce the number of patients who die within 24 hours after arrival in the hospital due to exsanguination by a minimum of 20% within the next 5 years.

O traumatismo raquimedular é uma agressão à medula espinhal que pode ocasionar danos neurológicos, tais como alteração das funções motora, sensitiva e autônoma. Este artigo tem como propósito relatar detalhadamente as principais complicações clínicas resultantes desse tipo de lesão, e apresentar as intervenções assistenciais de enfermagem que possam auxiliar na promoção do bem estar e na melhoria da qualidade de vida dos pacientes, seja em caráter de acometimento já instalado ou profilático.

Caracterização de cuidadores de vítimas de trauma crânio-encefálico em seguimento ambulatorial

O presente estudo caracterizou o cuidador familiar principal de 50 vítimas de trauma crânio-encefálico em seguimento ambulatorial, em um centro para atendimento de trauma na cidade de São Paulo, por meio de entrevista e análise de prontuário. Os resultados revelaram que os cuidadores tinham idade média de 44,90 anos, eram em sua maioria do sexo feminino, solteiros, católicos, não haviam completado o ensino fundamental e não tinham ocupação remunerada antes do trauma. A metade dos cuidadores principais era mãe da vítima, 22% esposa(o) e 18% irmã(ão). A presença do cuidador secundário foi observada em 48% dos casos avaliados.

Comparação entre instrumentos de mensuração das consequências do trauma crânio-encefálico

O trauma crânio-encefálico (TCE) é considerado a causa mais importante de incapacidades entre jovens e a mais freqüente causa neurológica de morbidade. Em conseqüência, há um crescente interesse em instrumentos para monitorizar a recuperação após sua ocorrência. Nesse contexto, a Escala de Resultados de Glasgow (ERG) e a Disability Rating Scale (DRS) são instrumentos bastante utilizados. A atual investigação tem como objetivo comparar os resultados observados com o uso da DRS, ERG original e ampliada. Para atingir esse propósito, foram avaliadas as conseqüências pós-trauma de 63 vítimas de TCE contuso, com idade entre 12 e 65 anos, em seguimento ambulatorial em um centro de trauma da cidade de São Paulo, entre seis meses e três anos após TCE. A comparação dos resultados permitiu concluir que, embora as três escalas fossem fortemente correlacionadas, a ERG ampliada destacou-se pela sua maior sensibilidade para detectar alterações nas vítimas com melhores condições pós-traumáticas.

Alterações e expectativas vivenciadas pelos indivíduos com lesão raquimedular e suas famílias

O objetivo do estudo foi identificar as principais alterações decorrentes da presença de um indivíduo com lesão medular no convívio familiar; bem como as expectativas relacionadas com essa condição. Trata-se de um estudo quali-quantitativo desenvolvido junto à 32 famílias de indivíduos com lesão raquimedular no município de Maringá-PR. Na análise dos dados, surgiram três categorias: Relação com os serviços de saúde; Relacionamento familiar e Expectativas em relação ao tratamento. Os resultados nos permitem inferir que as mudanças advindas com o trauma raquimedular alteram não apenas a vida dos indivíduos, mas a dinâmica e o relacionamento familiar. Por isso, considera-se fundamental que a família desses indivíduos seja assessorada em suas dificuldades para que possa prover a continuidade da assistência e contribuir para a melhoria da qualidade de vida de seus membros portadores de lesão raquimedular, ampliando as perspectivas de vida e as expectativas relacionadas ao tratamento.

Encontrar um novo sentido da vida: um estudo explicativo da adaptação após lesão medular

Este estudo teve como finalidade explorar e descrever o fenómeno de adaptação após lesão medular, enfatizando a explicação das estratégias de adaptação adotadas, e procurando identificar as implicações que têm nos cuidados de enfermagem. A metodologia utilizada foi a Qualitativa, tendo como referência metodológica a Grounded Theory. Para tal, foi dada voz ativa a nove indivíduos que sofreram lesão medular, com um percurso de adaptação de sucesso à nova condição, utilizando a entrevista semidirigida. Foi efetuada também análise documental de alguns relatos de vida, partindo para a análise dos dados à luz da Grounded Theory. Foi possível explicar o fenómeno de adaptação após lesão medular, sendo evidenciada a influência do encontro com um novo sentido da vida, na manutenção da disposição para gerir as consequências que advêm do confronto com uma lesão medular. O tema central do estudo prende-se assim com a dimensão espiritual da pessoa, o que antevê uma intervenção de enfermagem específica nesta área, junto do indivíduo após lesão medular.

Galveston Orientation Amnesia Test (GOAT)

O trauma crânio-encefálico contuso (TCEC) é freqüentemente seguido pela amnésia pós-traumática (APT), caracterizada como um estado transitório de confusão e desorientação. Sua duração tem sido utilizada para quantificar a gravidade do TCEC e prever distúrbios nas funções cognitivas, assim como para antever as alterações na capacidade funcional das vítimas pós-trauma. O Galveston Orientation Amnesia Test (GOAT) é o primeiro instrumento sistematizado criado e o mais amplamente utilizado para avaliar a APT. Este artigo apresenta esse instrumento, as bases conceituais para seu desenvolvimento e a adaptação e validação do GOAT para cultura brasileira. Além disso, descreve sua aplicação e comenta as restrições do seu uso. Resultados de pesquisas realizadas em nosso meio contribuíram para as evidências sobre a validade do GOAT. Também apontaram os indicadores do momento pós-trauma em que o GOAT deve ser aplicado e destacaram as dificuldades no uso desse instrumento.
