Comparison between the functional aspects of swallowing and clinical markers in ICU patients with Traumatic Brain Injury (TBI). / Comparação dos aspectos funcionais da deglutição e indicadores clínicos em pacientes com traumatismo cranioencefálico em UTI.

PURPOSE: To characterize and compare the functional aspects of swallowing and clinical markers in intensive care patients with traumatic brain injury (TBI) in Intensive Care Unit (ICU). METHODS: Participants of this study were 113 adults diagnosed with TBI. Data collection stage involved: clinical assessment of the risk for bronchoaspiration performed by a speech-language therapist; assessment of the functional level of swallowing (American Speech-Language-Hearing Association National Outcome Measurement System - ASHA NOMS ); assessment of the patient' health status (Sequential Organ Failure Assessment - SOFA). RESULTS: After the inclusion criteria were applied, patients were grouped according to their swallowing functional level: levels 1 and 2 - ASHA1 (n=25); levels 3, 4 and 5 - ASHA2 (n=37); levels 6 and 7 - ASHA3 (n=51). The statistical analyses indicated the following significant results: the ASHA3 group presented lower severity levels of TBI at the clinical assessment of bronchoaspiration, remained less time intubated (approximately um third less than the more severe group), remained fewer days in hospital and needed less therapy sessions to return to safe oral feeding. The clinical predictor signs for bronchoaspiration that best characterized the groups were the presence of altered auscultation and the presence of coughing after swallowing. Patients in the ASHA3 group presented these signs less frequently. CONCLUSION: The score obtained on the SOFA and the time of orotracheal intubation were identified as the prognostic indicators of functional swallowing. The presence of altered cervical auscultation and coughing were clinical predictors of dysphagia.

OBJETIVO: caracterizar e comparar os aspectos funcionais da deglutição e indicadores clínicos na população com traumatismo cranioencefálico (TCE) em unidade de terapia intensiva. MÉTODO: Participaram do estudo 113 adultos com diagnóstico de TCE. As etapas de coleta de dados envolveram: a avaliação fonoaudiológica clínica do risco de broncoaspiração, determinação do nível funcional da deglutição (American Speech-Language-Hearing Association National Outcome Measurement System ­ ASHA NOMS), determinação da gravidade clínica do indivíduo de acordo com a Sequential Organ Failure Assessment (SOFA). RESULTADOS: Após a aplicação dos critérios de inclusão, os pacientes selecionados foram agrupados de acordo com os níveis funcionais de deglutição: níveis 1 e 2 ­ ASHA1 (n=25); níveis 3, 4 e 5 ­ ASHA2 (n=37); níveis 6 e 7 ­ ASHA3 (n=51). As análises estatísticas indicaram os seguintes resultados significantes: o grupo ASHA3 apresentou menor gravidade do TCE no momento da avaliação fonoaudiológica, menor tempo de intubação orotraqueal (um terço a menos que o grupo mais grave), ficou menos tempo hospitalizado e necessitou de menos sessões de atendimento fonoaudiológico para o retorno seguro para via oral de alimentação. Os sinais clínicos preditores de broncoaspiração que mais diferenciaram os grupos foi a presença de ausculta cervical alterada e presença de tosse após a deglutição, sendo que o grupo ASHA3 apresentou esses sinais com menor frequência. CONCLUSÃO: O escore SOFA e o tempo de intubação orotraqueal foram indicadores do prognóstico da funcionalidade da deglutição. A presença ausculta cervical alterada e tosse foram preditores clínicos de disfagia.

Swallowing sounds in speech therapy practice: a critical analysis of the literature.

This study aimed to investigate international scientific papers published on the subject of cervical auscultation and its use in speech therapy. The study involved a qualitative review of the literature spanning the last 10 years. Articles were selected from the PubMed database using the following keywords: cervical auscultation, swallowing and swallowing disorders. Research was included that was conducted on adult humans (over 18 years of age) and was written in English. Each citation retrieved from the database was analyzed independently by each of the study researchers to ascertain its relevance for inclusion in the study. The methodology involved formulating the research question, locating and selecting studies and critically evaluating the articles according to the precepts of the Cochrane Handbook. As a result, 35 studies were identified; 13 articles were analyzed because they allowed access to the full text and were related directly to the subject. We found that the studies were performed with groups of healthy subjects and subjects with different types of base pathology. Some studies compared the patterns found in the different groups. Some of the research sought to study the pattern of swallowing sounds with different factors - evaluator experience, the specificity and sensitivity of the method and how to improve the technique of cervical auscultation through the use of instruments other than the stethoscope. The conclusion of this critical analysis is that cervical auscultation is an important tool to be used in conjunction with other assessment methods in the routine clinical evaluation of swallowing.

Sons da deglutição na prática fonoaudiológica: análise crítica da literatura / Swallowing sounds in speech therapy practice: a critical analysis of the literature

Este estudo objetivou pesquisar artigos científicos internacionais publicados sobre a ausculta cervical e sua utilização na prática fonoaudiológica. Trata-se de estudo de revisão qualitativa da literatura, envolvendo os últimos 10 anos. Os artigos foram selecionados da base de dados PubMed, utilizando os descritores: auscultation cervical, deglutition e deglutition disorders. A pesquisa deveria ter sido realizada com seres humanos, adultos (maiores que 18 anos) e escrita no idioma inglês. Cada citação recuperada no banco de dados foi analisada independentemente pelos pesquisadores do estudo, visando à pertinência de sua seleção e de sua inclusão ou não no estudo. A metodologia empregada envolveu a formulação da pergunta, a localização e seleção dos estudos, e a avaliação crítica dos artigos, conforme os preceitos do Cochrane Handbook. Como resultados, foram identificados 35 estudos, dos quais 13 foram analisados, pois permitiram acesso ao texto completo e relacionavam-se diretamente ao tema. Concluiu-se que os estudos foram realizados com grupos de sujeitos saudáveis e sujeitos com diferentes tipos de patologia de base. Alguns estudos compararam os padrões encontrados nos diferentes grupos. Constatou-se que parte dos artigos buscou estudar o padrão dos sons da deglutição, com diferentes interfaces: a experiência dos avaliadores; especificidade e sensibilidade do método; e como aprimorar a técnica da ausculta cervical por meio da utilização de outros instrumentos, diferentes do estetoscópio. Com essa análise crítica, concluiu-se que utilização da ausculta cervical é importante como um instrumento utilizado juntamente de outros, na rotina da avaliação clínica da deglutição.
