There was no mortality associated with the procedure. Conclusion: The findings in our study were similar to those reported in various international series.

Levantamento de dados de condenações pulmonares por aspiração de sangue em abate de suínos sob o Serviço de Inspeção Estadual da Bahia entre os anos de 2018 a 2020 / Data Survey on pulmonary condemnatios for blood aspiration in swine slaughter under the Bahia State, Brazil Inspection Service from 2018 to 2020

O presente estudo tem como objetivo descrever os dados das condenações de pulmões por aspiração de sangue em abate de suínos do estado da Bahia, no período de janeiro de 2018 a outubro de 2020, em abatedouros sob fiscalização do Serviço de Inspeção Estadual (SIE). A coleta retrospectiva foi facilitada pela Agência de Defesa Agropecuária da Bahia (ADAB), através da Guia de Trânsito Animal (GTA), e foram coletados dados de 255.834 suínos abatidos em matadouros frigoríficos, localizados em oito municípios. Nos anos de 2018 e 2019, a aspiração de sangue foi a lesão mais encontrada. Em 2018, foram 15,45% (1131/7322) das alterações macroscópicas e 36,48% (1131/3100) das condenações pulmonares, e em 2019, foram 14,75% (1053/7138) e 36,20% (1053/2909), respectivamente. A congestão foi a lesão mais encontrada em 2020, mas não houve diferença considerável com a aspiração de sangue, que foi destaque das condenações pulmonares, com 38,07% (712/1870). Estes dados revelam a frequência de condenação por aspiração de sangue no estado da Bahia e sugerem implementação de treinamentos de manejo não violento para os funcionários dos abatedouros frigoríficos, visto que esse tipo de lesão indica estresse e uma tecnopatia associada à falha na insensibilização e sangria, em razão do animal agonizar enquanto tenta respirar após a incisão no pescoço.

This study aims to analyze data on lung condemnations for blood aspiration in pig slaughter in the state of Bahia, Brazil from january 2018 to october 2020, in slaughterhouses under supervision of the State Inspection Service (SIE). The retrospective collection was facilitated by the Agricultural Defense Agency of Bahia (ADAB), through the Animal Transit Guide (GTA), and data were collected from 255,834 pigs slaughtered in slaughter houses located in eight municipalities. In 2018 and 2019, blood aspiration was the most common lesion. In 2018, it was 15,45% (1131/7322) of macroscopic changes and 36,48% (1131/3100) of lung condemnations, and in 2019, it was 14,75% (1053/7138) and 36,20% (1053/2909), respectively. Congestion was the most common lesion found in 2020, but there was no considerable difference with blood aspiration, which was highlighted in pulmonary condemnations, with 38,07% (712/1870). These data reveal the frequency of condemnations for blood aspiration in the state of Bahia, Brazil and suggest the implementation of training in non-violent management for employees of slaughterhouses, as this type of injury indicates stress and a technopathy as sociated with failure in stunning and bleeding, because the animal agonizes while trying to breathe after the neck incision

Associação entre o número de deglutições, resíduo faríngeo e broncoaspiração na esclerose múltipla / Association between the number of swallowing, pharyngeal residue and bronchopulmonary aspiration in multiple sclerosis

RESUMO Objetivo verificar a associação entre o número de deglutições e presença de resíduo faríngeo e broncoaspiração em pessoas com esclerose múltipla. Métodos estudo transversal observacional de exames de videofluoroscopia de 231 deglutições de indivíduos com esclerose múltipla. Três fonoaudiólogas avaliaram as deglutições de IDDSI 1 (International Dysphagia Diet Standardisation Initiative) (5 ml e 10 ml) e IDDSI 4 (8 ml) quanto à presença de resíduo faríngeo e de penetração/aspiração. Deglutições que não apresentaram resíduo faríngeo foram classificadas como deglutições sem resíduos faríngeos (DSR) e as que apresentaram, como deglutições com resíduos faríngeos (DCR), sendo estas últimas subdivididas em resíduos faríngeos em todas as ofertas ou eventuais (DCR1 e DCR2). O número de deglutições foi analisado por um avaliador cego e comparado com os dados demográficos e clínicos. Resultados das 231 deglutições, 73 (31,6%) apresentaram resíduos faríngeos. O número médio de deglutições foi semelhante nas deglutições sem e com resíduos faríngeos em cada consistência e volume e nas variáveis idade, gênero, tipo de esclerose múltipla e incapacidade funcional. Houve associação entre a média do número de deglutições e a ausência de penetração/aspiração, quando comparada às deglutições sem e com resíduos faríngeos, nas DCR2 e em indivíduos acima de 50 anos. Ao analisar intragrupo, observou-se associação nas DCR, sendo maior na ausência de penetração/aspiração e nas DCR2. Conclusão não houve correlação entre o número de deglutições e a presença de resíduos em recessos faríngeos na esclerose múltipla. Todavia, o número de deglutições foi maior quando houve resíduo e ausência de disfagia e de penetração/aspiração, em indivíduos mais velhos.

ABSTRACT Purpose To verify the association between the number of swallows and the presence of pharyngeal residue and bronchoaspiration in people with Multiple Sclerosis. Methods An observational cross-sectional study of videofluoroscopic examinations of 231 swallows from individuals with Multiple Sclerosis. Three speech therapists evaluated IDDSI 1 (International Dysphagia Diet Standardisation Initiative) (5ml and 10ml) and IDDSI 4 (8ml) deglutitions for pharyngeal residue and penetration/ aspiration. Swallows with no pharyngeal residue were classified as swallows without pharyngeal residue (SWTR) and those with pharyngeal residue (SWR), the latter subdivided into pharyngeal residue in all or occasional offerings (SWR1 e SWR2). The number of swallows was analyzed by a blind evaluator and compared with demographic and clinical data. Results Of the 231 swallows, 73 (31.6%) showed pharyngeal residues. The mean number of swallows was similar in the deglutitions with and without pharyngeal residues in each consistency and volume and in the variables age, gender, type of Multiple Sclerosis and functional disability. There was an association between the mean number of swallows and the absence of penetration/aspiration when comparing deglutitions with and without pharyngeal residues, in SWR2 and in individuals over 50 years of age. When analyzing intragroup, an association was observed in SWR, being higher in the absence of penetration/aspiration and in SWR2. Conclusion There was no correlation between the number of swallows and the presence of residues in pharyngeal recesses in multiple sclerosis. However, the number of swallows was higher when there was residue and absence of dysphagia and penetration/aspiration, and in older individuals.

Physicians' behavior regarding non-acceptance of oral restriction (nil per os) by dysphagic patient with risk of laryngotracheal aspiration / Comportamento do médico diante da não aceitação de restrição da via oral pelo paciente disfágico com risco de aspiração laringotraqueal

ABSTRACT Objective: To define physician´s behavior in the face of a mentally capable elderly dysphagic patients at risk of pulmonary aspiration, who do not accept oral restriction. Methods: Observational, cross-sectional study, presenting a clinical case of an independent elderly with clinical complaints of dysphagia and laryngotracheal aspiration by flexible endoscopic evaluation of swallowing who rejected the proposal to restrict oral diet. A questionnaire about the patient's decision-making process was used to assess whether the physician was sympathetic and justify their answer, and if they are aware of hierarchy of ethical principles (recognition of the person´s value, autonomy, beneficence, nonmaleficence and justice), in the decision-making process, and which was the main principle that guided their decision. Results: One hundred participants were classified by time since graduation as Group I (less than 10 years) and Group II (more than 10 years). Of them, 60% agreed with the patient's decision, with no difference between the groups. The main reason was autonomy of patients, in both groups. Among those who were not sympathetic, the main argument was beneficence and nonmaleficence, considering the risk between benefit and harm. As to awareness about the hierarchy of principles, we did not find differences between the groups. Autonomy was the principle that guided those who were sympathetic with the patient's decision, and justice among those who didnot agree. Conclusion: Physicians were sympathetic with the patient's decision regarding autonomy, despite the balance between risks of beneficence and nonmaleficence, including death. We propose to formalize a non-compliance term.

RESUMO Objetivo: Definir o comportamento médico diante de paciente idoso disfágico com risco de aspiração laringotraqueal e mentalmente capaz que não aceita a restrição da via oral. Métodos: Estudo observacional, transversal. Apresentamos um caso clínico de idoso, que vive independente, com queixas clínicas e videoendoscopia da deglutição comprovando disfagia e aspiração, que recusou a proposta de restrição da via oral. Um questionário foi aplicado sobre o processo de decisão do paciente, procurando avaliar se o médico torna-se solidário, e que justifique sua resposta, e se tem ciência da hierarquia dos princípios éticos (reconhecimento do valor da pessoa, autonomia, beneficência, não maleficência e justiça), no processo de decisão e qual o principal princípio que norteia sua decisão. Resultados: Cem participantes foram classificados por tempo de formados em Grupo I (até 10 anos) e Grupo II (mais de 10 anos). Deles 60% tornaram-se solidários à decisão do paciente, sem diferença entre os grupos. O principal argumento foi a autonomia do paciente nos dois grupos. Entre os não solidários, foi o binômio beneficência e não maleficência, e o balanço do risco/benefício e malefício. Considerando a ciência sobre a hierarquia dos princípios que regem a decisão, não encontramos diferença entre eles. A autonomia foi o principal princípio na decisão entre os solidários e a justiça entre os não solidários. Conclusão: O médico foi solidário à decisão do paciente em respeito à sua autonomia, apesar dos riscos ponderados da beneficência e da maleficência, inclusive de morte. Propomos o termo de recusa de conduta formalizada.

Algoritmo para el manejo de la aspiración pulmonar crónica en pediatría / Algorithm for the management of chronic pulmonary aspiration in pediatrics

La aspiración pulmonar es el pasaje de alimentos, reflujo gastroesofágico y/o saliva a la vía aérea de manera suficiente que ocasione síntomas respiratorios crónicos o recurrentes. Es una ausa importante de neumonía recurrente, enfermedad pulmonar progresiva, bronquiectasias e, incluso, muerte. La aspiración es intermitente y, con frecuencia, ocurre en niños con anomalías médicas subyacentes o síndromes que ocasionan síntomas respiratorios similares a la aspiración pulmonar crónica, por lo que, muchas veces, el diagnóstico de aspiración se demora hasta que haya una lesión pulmonar significativa. Se describen los métodos diagnósticos disponibles y sus limitaciones, y las opciones de tratamiento de la aspiración pulmonar crónica en la población pediátrica.

Pulmonary aspiration is the passage of food, gastroesophageal reflux and/or saliva to the airway in a manner sufficient to cause chronic or recurrent respiratory symptoms. It is an important cause of recurrent pneumonia, progressive lung disease, bronchiectasis and even death.Aspiration is intermittent and often occurs in children with underlying medical conditions or syndromes that cause respiratory symptoms similar to chronic pulmonary aspiration, so diagnosis of aspiration is often delayed until there is a significant lung injury. The available diagnostic methods and their limitations, and treatment options of chronic pulmonary aspiration in the pediatric population are described.

Relación del reflujo gastroesofágico y manifestaciones respiratorias, desde el punto de vista de la gastroenterología pediátrica / Relationship between gastroesophageal reflux and respiratory manifestations, from the pediatric gastroenterologist point of view

Gastroesophageal reflux is a frequent condition in the daily life of infants and older children. When reflux causes symptoms, it is called gastroesophageal reflux disease. Different extraesophageal symptoms have been frequently attributed to gastroesophageal reflux, however, new diagnostic techniques available, such as pHmetry with impedance measurement, have allowed us to evaluate and eventually dismiss such relationships. In this article we review the relationship between gastroesophageal reflux and laryngeal pathology, chronic cough, asthma and aspiration. In general terms, the empirical treatment of a presumed reflux is not recommended in asymptomatic patients, in whom its presence is not demonstrated by techniques such as pHmetry with impedance, given that therapeutic response is low and similar to placebo, with potential adverse effects.

El reflujo gastroesofágico es una condición frecuente en la vida diaria de lactantes y niños mayores. Cuando produce síntomas, se denomina enfermedad por reflujo gastroesofágico. Se ha atribuido frecuentemente diferentes síntomas extraesofágicos al reflujo, sin embargo, nuevas técnicas diagnósticas disponibles, como la pHmetría con medición de impedanciometría, han permitido evaluar y eventualmente descartar tales asociaciones. En este artículo se revisa la relación entre el reflujo gastroesofágico y patología laríngea, tos crónica, asma y aspiración. En términos generales, no se recomienda el tratamiento empírico de un supuesto reflujo en pacientes asintomáticos, en quienes tampoco esté demostrada su presencia por técnicas como la pHmetría con impedanciometría, dado que la respuesta terapéutica es baja y similar a placebo, con potenciales efectos adversos.

Ultrasound assessment of gastric antrum in term pregnant women before elective cesarean section / Ultrassom de antro gástrico em gestantes a termo antes de cesariana eletiva

Abstract Background and objectives: Pregnant women are considered patients at risk for pulmonary aspiration of gastric contents. The study aim was to evaluate the gastric antral cross-sectional area using ultrasound. Method: In this prospective study, 85 scheduled term pregnant women underwent gastric ultrasound. The outcomes were the measurement of the gastric antral cross-sectional area (main outcome), the estimated gastric volume, the incidence of pregnant women at risk for pulmonary aspiration, and the association between gastric antral cross-sectional area and clinical-demographic characteristics. Gastric antral cross-sectional area and gastric volume were compared according to body mass index <30 or ≥30. Results: The median (IIQ) for gastric antral cross-sectional area was 4 cm2 (2.8-6.3), for the estimated gastric volume it was 49.8 mL (33.7-87.2), and for the gastric volume estimated in mL.kg-1 it was 0.62 mL.kg-1 (0.39-0.95). The 95th percentile [95% confidence interval (CI)] of the gastric antral cross-sectional area and the estimated gastric volume were ≤10.3 cm2 (95% CI: 7.6-15.6) and 1.42 mL.kg-1 (95% CI: 1.20-2.64), respectively. The incidence of pregnant women at risk for pulmonary aspiration was 3.5% (CI: 3.5 (1.2-9.8)). There was a positive correlation between gastric antral cross-sectional area and weight, p < 0.001 and body mass index <0.001. Patients with a body mass index ≥30 had a gastric antral cross-sectional area and an estimated gastric volume greater than those with a body mass index <30, respectively, p < 0.01 and p < 0.02. Conclusion: Measuring the gastric antral cross-sectional area of pregnant women is feasible and easy. There was positive correlation between gastric antral cross-sectional area, body weight and body mass index. The estimation of gastric volume by measuring the gastric antral cross-sectional area can identify patients at risk for pulmonary aspiration. Obese patients had a gastric antral cross-sectional area and an estimated gastric volume greater than non-obese patients.

Resumo Justificativa e objetivos: As gestantes são consideradas pacientes de risco para aspiração pulmonar do conteúdo gástrico. O objetivo foi avaliar a área transversal do antro gástrico por meio de ultrassonografia. Método: Neste estudo prospectivo, 85 gestantes a termo agendadas foram submetidas à ultrassonografia do antro gástrico. Os desfechos foram a mensuração da área transversal do antro gástrico (desfecho principal), a estimativa do volume gástrico, a incidência de gestantes sob risco de aspiração pulmonar, a associação entre a área transversal do antro gástrico e características clínico-demográficas. A área transversal do antro gástrico e do volume gástrico foi comparada de acordo com o índice de massa corporal < 30 ou ≥ 30. Resultados: A mediana (IIQ) da área transversal do antro gástrico foi 4 cm2 (2,8-6,3), do volume gástrico estimado 49,8 mL (33,7-87,2) e do volume gástrico estimado em mL.kg-1 de 0,62 mL.kg-1 (0,39-0,95). O percentil 95 [intervalo de confiança (IC) 95%] da área transversal do antro gástrico e do volume gástrico estimado foi ≤ 10,3 cm2 (IC 95%: 7,6-15,6) e 1,42 mL.kg-1 (IC 95%: 1,20-2,64), respectivamente. A incidência de gestantes sob risco de aspiração pulmonar foi de 3,5% (IC: 3,5 (1,2-9,8). Houve correlação positiva entre a área transversal do antro gástrico e peso, p < 0,001 e índice de massa corporal p < 0,001. As pacientes com índice de massa corporal ≥ 30 apresentaram maior área transversal do antro gástrico, e do volume gástrico estimado, do que as com índice de massa corporal < 30, respectivamente p < 0,01 e p < 0,02. Conclusão: A mensuração da área transversal do antro gástrico de gestantes é factível e fácil. A área transversal do antro gástrico correlacionou-se positivamente com peso e índice de massa corporal. A estimativa do volume gástrico através da mensuração da área transversal do antro gástrico pode identificar pacientes sob risco de aspiração pulmonar. As pacientes obesas apresentaram área transversal do antro gástrico e volume gástrico estimado maior do que as não obesas.

Ocorrência de alterações pulmonares em bovinos abatidos em abatedouro-frigorífico na cidade de Belém, Pará, Brasil / Pulmonary alterations in bovine abated in slaughterhouse in the city of Belém, Pará, Brazil

A inspeção post mortem de bovinos destinados ao consumo humano, favorece a obtenção de diagnósticos de doenças. As alterações pulmonares são de interesse para a inspeção sanitária, pois são frequentemente encontradas em bovinos abatidos para consumo em estabelecimentos com serviço oficial de inspeção. O objetivo do trabalho foi levantar a ocorrência de alterações pulmonares que podem ter sido ocasionadas pela insensibilização inadequada em bovinos abatidos para consumo em abatedouro-frigorífico localizado em Belém, Estado do Pará. Avaliou-se 5.654 animais, sendo condenados 603 pulmões que corresponderam a 258 (42,78%) condenações por aspiração de conteúdo ruminal; 191 (31,67%) por enfisema e 154 (25,53%) por aspiração de sangue. Os resultados obtidos podem ter sido decorrentes do método de insensibilização utilizado no estabelecimento.

Exogenous lipoid pneumonia presented by acute eosinophilic pneumonia

Exogenous lipoid pneumonia is an uncommon medical condition resulting from aspiration or inhalation of oily material. Generally, lipoid pneumonia has nonspecific clinical and radiological presentations, and may be misdiagnosed as bacterial pneumonia or lung cancer. We describe an unusual case of exogenous lipoid pneumonia accompanied by peripheral blood and pulmonary eosinophilia. A 63-year-old man was admitted with progressively worsening exertional dyspnea and productive cough for 5 days. A chest radiograph showed abnormalities in the lower lobe of the right lung, and a diagnosis of community-acquired pneumonia was made; intravenous antibiotics were administered. However, dyspnea and hypoxia gradually worsened and peripheral blood eosinophilia developed. A bronchoscopy was performed and bronchoalveolar lavage fluid analysis showed markedly increased numbers of eosinophils (40%). Subsequently, a comprehensive review of history revealed that he fell asleep with camellia oil in his mouth for 2 weeks to relieve foreign body sensation of the throat. Sputum and bronchoalveolar lavage fluid cytology showed the presence of lipid-laden macrophages. He was diagnosed with lipoid pneumonia and acute eosinophilic pneumonia. Chest radiograph and symptom were rapidly improved after treatment with intravenous methylprednisolone.

Risk Factors and Assessment of Aspiration / 대한연하장애학회지

Aspiration is the entry of materials, such as pharyngeal secretions, food, or stomach contents, into the respiratory system. Dysphagia is the most common risk factor of aspiration, but there are many other risk factors. A single factor or multiple factors may be present to induce the aspiration, and the risk factors of aspiration should be considered multidimensional. The bedside water test is suitable as a screening test for an evaluation of aspiration. Videofluoroscopic swallowing study and flexible endoscopic evaluation of swallowing are the diagnostic tests of aspiration and the tests are required if the screening test shows signs of aspiration or silent aspiration is strongly suspected. The diagnostic test should assess not only the presence of aspiration, but also the pathophysiologic risk factors of aspiration.

A Case Report of Spontaneous Passage of Bronchial Foreign Body through Gastrointestinal Tract

Foreign body aspiration is most likely to occur in children and in adults aged above 60 years, causing a respiratory emergency, such as airway closure. It is diagnosed based on a history of aspiration, presenting symptoms, and radiographic findings. The treatment may include removal of the foreign body via bronchoscopy or surgery. Here, we report a rare case of bronchial aspiration of a foreign body, confirmed with clinical and radiographic examinations, in a 57-year-old patient. The patient was transferred for treatment; however, spontaneous passage of the foreign body to the gastrointestinal tract led to its removal from the bronchus.

Anestesia locorregional en una paciente adulta con síndrome de Prader-Willi: consideraciones anestésicas / Anesthetic consideration: Regional anesthesia with Prader-Willi

Prader-Willi syndrome (PWS) is a disorder caused by a genetic alteration that causes a multisystem clinic. It can be due mainly to three genetic mechanisms; a paternal deletion of the 15q11-13 region, a maternal uniparental disomy, or an imprinting defect. The paternal deletion is observed in 70% of the patients, the disomy in 25% and the imprinting defect in only 5% of those affected by this syndrome. 1) It is the most common syndromic cause of obesity with an estimated prevalence in the population of 1: 50,000; 2) The clinic is very variable, which is why clinical criteria have been created that, supported by the genetic study, confirm the diagnosis; 3) They have difficulty feeding during lactation, which leads to hyperphagia in childhood that leads to obesity. In the adult stage, in addition to obesity, respiratory pathology, sleep disturbances and psychological disorders stand out; 4) Objective: the aim of the present review was to compile the cases recorded in the scientific literature of patients anesthetized with PWS and the anesthetic options used in said patients.

El síndrome de Prader-Willi (SPW) es un trastorno causado por una alteración genética que provoca una clínica multisistémica. Puede ser debido principalmente a tres mecanismos genéticos; una deleción paterna de la región 15q11-13, una disomía uniparental materna o un defecto de impronta. La deleción paterna se observa en el 70% de los pacientes, la disomía en el 25% y el defecto de impronta en tan solo el 5% de los afectados por este síndrome. 1) Constituye la causa sindrómica más frecuente de obesidad con una prevalencia estimada en la población de 1:50.000; 2) La clínica es muy variable por lo que se han creado unos criterios clínicos que apoyados por el estudio genético confirman el diagnóstico; 3) Presentan dificultad para la alimentación durante la lactancia, que da paso a una hiperfagia en la infancia que deriva en obesidad. En la etapa adulta, además de la obesidad destacan la patología respiratoria, alteraciones del sueño y trastornos psicológicos; 4) Objetivo: el objetivo de la presente revisión fue recopilar los casos registrados en la literatura científica de pacientes anestesiados con SPW y las opciones anestésicas utilizadas en dichos pacientes.

Predictive factors for oropharyngeal dysphagia after prolonged orotracheal intubation / Predictive factors for oropharyngeal dysphagia after prolonged orotracheal intubation

Abstract Introduction: Lesions in the oral cavity, pharynx and larynx due to endotracheal intubation can cause reduction in the local motility and sensitivity, impairing the swallowing process, resulting in oropharyngeal dysphagia. Objective: To verify the predictive factors for the development of oropharyngeal dysphagia and the risk of aspiration in patients with prolonged orotracheal intubation admitted to an intensive care unit. Methods: This is an observational, analytical, cross-sectional and retrospective data collection study of 181 electronic medical records of patients submitted to prolonged orotracheal intubation. Data on age; gender; underlying disease; associated comorbidities; time and reason for orotracheal intubation; Glasgow scale on the day of the Speech Therapist assessment; comprehension; vocal quality; presence and severity of dysphagia; risk of bronchoaspiration; and the suggested oral route were collected. The data were analyzed through logistic regression. The level of significance was set at 5%, with a 95% Confidence Interval. Results: The prevalence of dysphagia in this study was 35.9% and the risk of aspiration was 24.9%. As the age increased, the altered vocal quality and the degree of voice impairment increased the risk of the presence of dysphagia by 5-; 45.4- and 6.7-fold, respectively, and of aspiration by 6-; 36.4- and 4.8-fold. The increase in the time of orotracheal intubation increased the risk of aspiration by 5.5-fold. Conclusion: Patients submitted to prolonged intubation who have risk factors associated with dysphagia and aspiration should be submitted to an early speech-language/audiology assessment and receive appropriate and timely treatment. The recognition of these predictive factors by the entire multidisciplinary team can minimize the possibility of clinical complications inherent to the risk of dysphagia and aspiration in extubated patients.

Resumo: Introdução: Lesões na cavidade oral, faringe e laringe, em virtude de intubação endotraqueal, podem causar redução da motricidade e da sensibilidade local e comprometer o processo da deglutição, determinando disfagia orofaríngea. Objetivo: Verificar os fatores preditivos do desenvolvimento de disfagia orofaríngea e risco de aspiração em pacientes pós-intubação orotraqueal prolongada internados em uma unidade de terapia intensiva. Método: Estudo observacional, analítico, de delineamento transversal e retrospectivo de coleta de dados de 181 prontuários eletrônicos, de pacientes submetidos à intubação orotraqueal prolongada. Foram coletadas informações referentes a idade; sexo; doença de base, comorbidades associadas; tempo e motivo da intubação orotraqueal; Escala Glasgow no dia da avaliação fonoaudiológica; compreensão; qualidade vocal; presença de disfagia e a gravidade; risco de broncoaspiração; e via oral sugerida. Os dados foram analisados por meio da regressão logística. Adotou-se o nível de significância de 5% e intervalo de confiança de 95%. Resultados: A prevalência de disfagia neste estudo foi de 35,9% e de risco de aspiração de 24,9%. O aumento da idade, a qualidade vocal alterada e o grau de comprometimento da voz elevam os riscos de presença em disfagia em 5; 45,4 e 6,7 vezes, respectivamente, e de aspiração em 6; 36,4 e 4,8 vezes. Já o aumento do tempo de intubação orotraqueal elevou em 5,5 vezes o risco de aspiração. Conclusão: Pacientes submetidos a intubação prolongada que apresentam os fatores de risco relacionados às disfagia e aspiração devem ser submetidos a avaliação fonoaudiológica precoce e receber conduta adequada em tempo hábil. O reconhecimento desses fatores preditivos por toda a equipe multidisciplinar pode minimizar as possibilidades de complicações clínicas inerentes ao risco de disfagia e aspiração em pacientes extubados.

Abordaje diagnóstico para aspiración de cuerpo extraño en pediatría / Diagnostic approach of foreign body aspiration in pediatrics

Foreign body aspiration in children is a frequent cause of consultation in the pediatric emergency department and can be a life-threatening event. It occurs mainly during the first 4 years of life and is more frequent in males. It is possible to find the clinical triad of cough, localized wheezing and decrease of respiratory noises in 50 percent of cases. The diagnosis is based on an adequate clinical history to detect an asphyxiation event. Chest radiography is an important diagnostic tool although it is possible to find normal results in 12 to 25 percent of cases. Several studies have reported the usefulness of flexible bronchoscopy in extracting foreign bodies; however, rigid bronchoscopy remains the best choice for foreign body aspiration

La aspiración de cuerpo extraño en niños es una causa frecuente de consulta en el departamento de urgencias pediátricas y puede ser un evento potencialmente mortal. Se presenta principalmente durante los primeros 4 años de vida y es mas frecuente en el género masculino. Clínicamente es posible encontrar en un 50 por ciento de los casos la triada clínica de tos, sibilancias localizadas y disminución de ruidos respiratorios. El diagnóstico se basa en una historia clínica adecuada en la cual se busca intencionadamente el antecedente de un evento de asfixia. La radiografía de tórax es una herramienta importante para el diagnóstico aunque es posible encontrarla normal del 12 al 25 por ciento de los casos. Diversos estudios reportan la utilidad de la broncoscopia flexible en la extracción de cuerpos extraños, sin embargo la broncoscopia rígida continua siendo el estándar de oro para el manejo de la aspiración de cuerpo extraño

Pulmonary aspiration during intubation in a high-risk patient: A video clip and clinical implications

We report a case of pulmonary aspiration during induction of general anesthesia in a patient who was status post esophagectomy. Sudden, unexpected aspiration occurred even though the patient had fasted adequately (over 13 hours) and received rapid sequence anesthesia induction. Since during esophagectomy, the lower esophageal sphincter is excised, stomach vagal innervation is lost, and the stomach is flaccid, draining only by gravity, the patient becomes vulnerable to aspiration. As the incidence of perioperative pulmonary aspiration is relatively low, precautions to prevent aspiration tend to be overlooked. We present a video clip showing pulmonary aspiration and discuss the literature concerning the risk of aspiration and its preventive strategies.

Muertes por Hemoaspiración en Costa Rica en el año 2015 / Deaths from Hemoaspiration in Costa Rica in 2015

Resumen:La aspiración de sangre en las vías respiratorias es un resultado frecuente de las autopsias en casos de trauma, este hallazgo se relaciona a fracturas de la base del cráneo con laceraciones de la naso y orofaringe.La hemorragia pulmonar aguda antes de la muerte puede aparecer como sangrado dentro del árbol bronquial y ocasionalmente proximal a la tráquea, debido a causas traumáticas o no traumáticas.En este estudio se reportan casos de hemoaspiración ocurridos en víctimas fallecidas, siendo un hallazgo forense frecuente, se contabilizaron 3148 víctimas fallecidas en el año 2015, se tomaron los casos que tenían evidencia en la autopsia de sangre en los pulmones y/o en las vías aéreas. Se obtuvo un total de 37 víctimas con dicho diagnóstico forense, con predominio en hombres entre los 21 y 30 años de edad y seguido por hombres entre los 31 y 40 años de edad. Se documentó una mayorincidencia en los meses de abril y diciembre los cuales coinciden con los meses festivos en Costa Rica y la causa de muerte predominante fue accidental, seguido por homicidio y suicidio.

Abstract:Airway blood aspiration is a frequent result in trauma patient autopsies; it's generally associated with skull base fractures with naso and oropharynx.Acute pulmonary hemorrhage prior to death can appear as bleeding in lower airways in traumatic and non-traumatic cases.Occasionally it can also appear in upper respiratory airways as well.In this study we evaluate blood aspiration in dead victims. A total of 3148 victims deceased in 2015, 37 had pulmonary or lower airway hemorrhage as a forensic diagnose, a higher incidence in males was found with ages between 21 and 30 years, followed by males between 31 and 40 years old. The peak incidence was in the months of April and December, which are months with a high amount of holidays in Costa Rica, the predominant cause of death was accidental, followed by homicide and suicide.

Modificação da voz após deglutição: compatibilidade com achados da videofluoroscopia / Postswallow voice modification: compatibility with videofluoroscopy findings

RESUMO Objetivo Verificar se a modificação da voz após a deglutição relaciona-se com os dados do exame de videofluoroscopia. Método 27 indivíduos com disfagia orofaríngea realizaram a gravação da vogal sustentada /a/ antes e após a deglutição durante exame de videofluoroscopia. Utilizou-se a escala GRBAS e acrescentou-se o aspecto voz molhada para avaliação dos dados. Em relação ao exame, verificou-se estase de alimento em valéculas e recessos piriformes, penetração laríngea, aspiração traqueal e grau de disfagia. Resultados Houve diminuição do grau de alteração e astenia e aumento da tensão fonatória após a deglutição, sem diferença para o parâmetro voz molhada. Obteve-se sensibilidade e especificidade de ±50% para estase em recessos piriformes e valéculas; porém, sensibilidade de 80% para detecção de penetração e de 66-75% para aspiração e modificação da tensão fonatória, com 77-91% de valores preditivos negativos para os três parâmetros de avaliação, sem correlação com o grau de disfagia. Conclusão A modificação dos parâmetros da escala GRBAS após a deglutição apresentou boa compatibilidade com achados da videofluoroscopia.

ABSTRACT Purpose Verify whether voice modification after swallowing is associated with videofluoroscopic examination data. Methods 27 patients with oropharyngeal dysphagia underwent recording of sustained phonation of vowel /a/ before and after swallowing during videofluoroscopy. The GRBAS scale and the wet voice parameter were used to evaluate the data. Videofluoroscopy results showed stasis of food in the valleculae and piriform recesses, laryngeal penetration, tracheal aspiration, and degree of dysphagia. Results Decreased dysphonia grade and asthenia and increased strain were observed after swallowing, with no difference for the wet voice parameter. Sensitivity and specificity of ± 50% were observed for food stasis in the valleculae and piriform recesses. Sensitivity values of 80 and 66-75% were observed for detection of laryngeal penetration and tracheal aspiration and modification of vocal strain, respectively. Negative predictive values of 77-91% were found for the three assessment parameters with no correlation with the degree of oropharyngeal dysphagia. Conclusion Modification of the GRBAS scale parameters after swallowing showed good compatibility with videofluoroscopy findings.
