RESUMO

Introducción: La valoración de la capacidad tusígena se realiza con la medición del flujo espiratorio máximo durante la tos (peak-flow tos [PFT]). Sin embargo, esta valoración podría alterarse por enfermedades con obstrucción espiratoria de la vía aérea. El objetivo fue valorar la medición de la capacidad tusígena mediante PFT en pacientes con enfermedad pulmonar obstructiva crónica (EPOC), así como las correlaciones con la función pulmonar, muscular respiratoria y orofaríngea. Métodos: Se seleccionaron los pacientes con EPOC y con enfermedad neuromuscular, así como los sujetos sanos a los que se había realizado una medición de la fuerza de los músculos respiratorios de forma asistencial. De esta población, se analizaron los valores de la función respiratoria, así como la fuerza muscular orofaríngea. En un subgrupo de pacientes con EPOC se realizó el estudio de deglución por videofluoroscopia. Resultados: Se incluyeron 307 sujetos (59,3% EPOC, 38,4% enfermedades neuromusculares y 2,3% sanos). En el grupo EPOC, el PFT se encontraba disminuido de forma estadísticamente significativa comparado tanto con el grupo de los sanos como con los enfermos neuromusculares. El 70% de los EPOC tenían una disminución patológica del PFT. Solamente, existía una correlación directa entre el PFT con el grado de obstrucción bronquial y la fuerza de los músculos espiratorios. No se encontró alteración de la función de los músculos inspiratorios ni orofaríngeos. Conclusiones: La utilización del PFT en los pacientes con EPOC no refleja la capacidad tusígena ya que se ve influenciada por el grado de obstrucción bronquial. Por tanto, se deberían valorar nuevas pruebas diagnósticas para la medición de la capacidad tusígena, fundamentalmente, en los pacientes que coexistan enfermedades neuromusculares y patología obstructiva bronquial grave.(AU)


Introduction: Cough capacity is assessed by measuring cough peak flow (CPF). However, this assessment could be altered by obstructive airway diseases. The aim was to assess measurement of cough capacity by CPF in patients with chronic obstructive pulmonary disease (COPD), as well as correlations with pulmonary, respiratory muscle, and oropharyngeal function. Methods: Patients with COPD, and with neuromuscular disease, were selected as well as healthy subjects who had undergone respiratory muscle strength measurement in a healthcare setting. From this population, respiratory function values and lung and oropharyngeal muscle function were analysed. A subgroup of COPD patients underwent a videofluoroscopic swallow study. Results: Three hundred and seven subjects were included (59.3% COPD, 38.4% neuromuscular diseases, and 2.3% healthy). CPF was found to be statistically significantly decreased in the COPD group compared to both the healthy and neuromuscular disease groups. Of the COPD patients, 70% had a pathological decrease in CPF. There was only a direct correlation between CPF with the degree of bronchial obstruction and expiratory muscle strength. No alteration of inspiratory or oropharyngeal muscle function was found. Conclusions: The use of CPF in COPD patients does not reflect cough capacity as it is influenced by the degree of bronchial obstruction. Therefore, new diagnostic tests to measure cough capacity should be considered, especially in patients with coexisting neuromuscular diseases and severe bronchial obstructive disease.(AU)
