Focused Assessment with Sonography for Trauma (FAST).

The main cause of death in traumas is hypovolemic shock. Physical examination is limited to detect hemopericardium, hemoperitoneum, and hemopneumothorax. Computed tomography (CT) is the gold standard for traumatic injury evaluation. However, CT is not always available, is more expensive, and there are transportation issues, especially in hemodynamically unstable patients. In this scenario, a rapid, reproducible, portable, and noninvasive method such as ultrasound emerged, directed for detecting hemopericardium, hemoperitoneum, and hemopneumothorax, in a "point of care" modality, known as the focused assessment with sonography for trauma (FAST) protocol. With decades of experience, spread worldwide, and recommended by the most prestigious trauma care guidelines, FAST is a bedside ultrasound to be performed when accessing circulation issues of trauma patients. It is indicated to hemodynamically unstable patients with blunt abdominal trauma, with penetrating trauma of the thoracoabdominal transition (where there is doubt of penetrating the abdominal cavity) and for any patient with the cause of the instability unknown. There are four regions to be examined in the traditional FAST protocol: pericardium (to detect cardiac tamponade), right upper abdominal quadrant, left upper abdominal quadrant, and pelvis (to detect hemoperitoneum). The called extended FAST (e-FAST) protocol also searches the pleural spaces for hemothorax and pneumothorax. It is important to know the false positives and false negatives of the protocol, as well as its limitations. FAST/e-FAST protocol is designed to provide a simple "yes or no" answer regarding the presence of bleeding. It is not intended to quantify the bleeding nor evaluate organ lesions due to its limited accuracy for these purposes. Moreover, the amount of bleeding and/or the identification of organ lesions will not change patient's management: Hemodynamically unstable patients with positive FAST must go to the operating room without delay. CT should be considered for hemodynamically stable patients.

Diagnostic precision for bronchopulmonary aspiration in a heterogeneous population. / Precisão diagnóstica para o risco de broncoaspiração em população heterogênea.

PURPOSE: The purpose of the present study was to assess the validity of a simple instrument for screening dysphagia used in a large public hospital in Brazil with heterogeneous adult population. METHOD: The Dysphagia Risk Evaluation Protocol (DREP) - screening version contains four items (altered cervical auscultation, altered vocal quality, coughing and choking before / during / after swallowing) that were previously indicated as independent risk factors associated to the presence of dysphagia in the swallowing test with water. Trained speech therapists administered and scored DREP - screening version to consecutive patients referred by hospital's medical team to perform Video Fluoroscopic for Swallowing Study (VFSS). RESULTS: 211 patients received the swallowing screen (DREP): 99 failed and 112 passed. One in every five patients was randomized to receive a VFSS. The DREP screening version demonstrated excellent validity with sensitivity at 92.9%, specificity at 75.0%, negative predictive values at 95.5% and an accuracy of 80.9%. CONCLUSION: The DREP - screening version is a simple and accurate tool to identify the risk for penetration and / or aspiration in patients who are not tube-fed, who have a good level of alertness, have no history of recurrent pneumonia, are not on pneumonia, and that do not use a tracheostomy cannula.

OBJETIVO: O objetivo do presente estudo foi realizar a validação de um instrumento simples de triagem da disfagia utilizado em um hospital público de grande porte no Brasil em população adulta heterogênea. MÉTODO: O Protocolo de Avaliação de Risco para Disfagia versão de triagem (PARDt) contém quatro itens (ausculta cervical alterada, alteração da qualidade vocal, tosse e engasgo antes/durante/após a deglutição) que foram previamente indicados como fatores de risco independentes associados à presença de disfagia no teste de deglutição com água. Fonoaudiólogos treinados administraram e classificaram o PARDt para pacientes consecutivos encaminhados pela equipe médica do hospital para realizar a videofluoroscopia da deglutição (VDF). RESULTADOS: 211 pacientes foram submetidos ao PARDt: 99 falharam e 112 passaram. Um em cada cinco pacientes foram randomicamente selecionados para VDF. O PARDt apresentou excelente validade: sensibilidade de 92,9%; especificidade de 75,0%; valores preditivos negativos de 95,5%; acurácia de 80,9%. CONCLUSÃO: O PARDt é uma ferramenta simples e precisa para identificar o risco de penetração e/ou aspiração em pacientes que não são alimentados por sonda, que apresentam bom nível de alerta, sem histórico de pneumonias de repetição, que não estejam em vigência de pneumonia e que não façam uso de cânula de traqueostomia.

Screening protocol for dysphagia in adults: comparison with videofluoroscopic findings

OBJECTIVES: To compare the videofluoroscopic findings of patients with suspected oropharyngeal dysphagia with the results of a clinical screening protocol. METHODS: A retrospective observational cohort study was conducted on all consecutive patients with suspected oropharyngeal dysphagia between March 2015 and February 2016 who were assigned to receive a videofluoroscopic assessment of swallowing. All patients were first submitted to videofluoroscopy and then to the clinical assessment of swallowing. The clinical assessment was performed within the first 24 hours after videofluoroscopy. The videofluoroscopy results were analyzed regarding penetration/aspiration using an 8-point multidimensional perceptual scale. The accuracy of the clinical protocol was analyzed using the sensitivity, specificity, likelihood ratios and predictive values. RESULTS: The selected sample consisted of 50 patients. The clinical protocol presented a sensitivity of 50% and specificity of 95%, with an accuracy of 88%. "Cough" and "wet-hoarse" vocal quality after/during swallowing were clinical indicators that appeared to correctly identify the presence of penetration/aspiration risk. CONCLUSION: The clinical protocol used in the present study is a simple, rapid and reliable clinical assessment. Despite the absence of a completely satisfactory result, especially in terms of the sensitivity and positive predictive values, we suggest that lower rates of pneumonia can be achieved using a formal dysphagia screening method.

Swallowing transit times and valleculae residue in stable chronic obstructive pulmonary disease.

BACKGROUND: Breathing and swallowing are physiologically linked to ensure effortless gas exchange during oronasal breathing and to prevent aspiration during swallowing. Studies have indicated consistent aspiration in chronic obstructive pulmonary disease, mainly related to delayed swallowing reflex and problems with lingual propulsion and pharyngeal peristalsis as a result of bilateral weakness and incoordination of the related muscles. The purpose of the present study was to evaluate swallowing transit times and valleculae residue characteristics of stable COPD patients who have no swallowing complaints. METHODS: Our study population included 20 stable patients with COPD and no swallowing complaints and 20 healthy controls. Swallowing was assessed through videofluoroscopic examination and involved the analysis of the following parameters: (1) pharyngeal stages of deglutition; (2) the duration of bolus movement through the oral cavity and pharynx (i.e. transit times); (3) valleculae residue ratio; (4) penetration/aspiration. RESULTS: Participants of the study did not present any signs of penetration-aspiration for any of the tested consistencies. Patients with COPD presented longer pharyngeal transit times during the ingestion of the liquid consistency and during the ingestion of the paste consistency. Regarding the duration of tongue base contact with the posterior pharyngeal wall, COPD patients also presented longer durations for the liquid and paste consistencies. No significant difference was observed for the distribution of individuals among the different valleculae residue severity levels. CONCLUSIONS: Our study suggests that stable COPD patients may present physiological adaptations as a protective swallowing maneuver to avoid aspiration/penetration of pharyngeal contents. Moreover, valleculae residue cannot be seen as an isolated factor when trying to explain swallowing alterations in this population.

Análise videofluoroscópica bidimensional perceptual da fase faríngea da deglutição em indivíduos acima de 50 anos / Two-dimensional perceptual videofluoroscopic swallowing analysis of the pharyngeal phase in patients older than 50 years

RACIONAL: A videofluoroscopia é considerada o procedimento "padrão-ouro" para avaliação da deglutição pela maioria das unidades que atendem pacientes com disfagia, tendo grande impacto na tomada de decisão, não só em termos terapêuticos, como também na determinação do prognóstico. OBJETIVO: Propor e verificar a reprodutibilidade de protocolo de análise videofluoroscopica bidimensional perceptual da fase faríngea da deglutição em uma população de adultos saudáveis. MÉTODOS: Participaram desta pesquisa 20 indivíduos saudáveis, de ambos os gêneros, com idades entre 50 e 65 anos. O exame foi realizado durante a ingestão de "alimentos" com as seguintes consistências: 10 ml de líquido; 7 ml de pastoso; e meio biscoito do tipo "água e sal". O protocolo proposto foi composto de quatro partes: avaliação do tempo de trânsito faríngeo; avaliação da duração do contato da base de língua na parede posterior da faringe; avaliação da porcentagem de resíduo alimentar em valécula; avaliação de penetração e aspiração na árvore respiratória. A análise estatística envolveu a avaliação da reprodutibilidade do método de análise entre avaliadores e a análise dos dados quantitativos, levando-se em consideração os gêneros. RESULTADOS: Pela análise comparativa entre os avaliadores houve alta reprodutibilidade. Não foram encontradas diferenças estatisticamente significantes para o tempo de trânsito faríngeo; para a duração do contato da base de língua na parede posterior da faringe e para a porcentagem de resíduo na valécula. Os resultados sugerem que os parâmetros de deglutição avaliados não tem diferença entre os gêneros. CONCLUSÃO: As análises asseguram a reprodutibilidade do protocolo proposto para análise bidimensional perceptual da videofluoroscopia. O resíduo na valécula mostrou-se presente em 40% da amostra, sugerindo que este parâmetro, isoladamente, não é indicativo de alteração na fase faríngea da deglutição.

BACKGROUND: Videofluoroscopy is considered the "gold standard" procedure for the evaluation of swallowing by most units that treat patients with dysphagia, having a great impact in decision making, not only in therapeutic terms, but also in determining the prognosis. AIM: To propose and to verify the reproducibility of the results of a perceptual two-dimensional videofluoroscopic protocol for the analysis of the pharyngeal phase of swallowing in a population of healthy adults. METHODS: Participants were 20 healthy adults, of both genders, with ages between 50 and 65 years. Videofluoroscopy was performed during the swallow of the following consistencies: 10 ml of liquid; 7 ml of paste; and half a "salt and water" biscuit. The protocol was composed by four parts: assessment of the pharyngeal transit time; assessment of the duration of the tongue base movement to the posterior pharyngeal wall; valleculae residue ratio; assessment of penetration/aspiration. Statistical analysis involved the assessment of data reproducibility between raters and analysis of the quantitative data regarding gender. RESULTS: Comparison among raters indicated that data was highly reproducible. No significant differences were found between genders for pharyngeal transit time; for the duration of the tongue base movement to the posterior pharyngeal wall; and for the valleculae residue ratio. CONCLUSION: The perceptual two-dimensional videofluoroscopy analysis demonstrated to be a reproducible method. Valleculae residue was present in 40% of the study sample, suggesting that this parameter alone does not indicate alterations of the pharyngeal phase of swallowing.
