RESUMO

There is an anatomical and physiological relationship between breathing and swallowing, the temporal coordination between these two functions are essential to maintain ventilation and to prevent pulmonary aspiration. Changes in the breathing and ventilation patterns can have an influence on the coordination of swallowing and respiration. Patients with chronic lung diseases may be susceptible to changes in the coordination between swallowing and breathing due to ventilatory functional changes. The purpose of this research was to identify symptoms of dysphagia in patients with chronic obstructive pulmonary disease (COPD), through the application of a screening questionnaire for dysphagia. Participants of the research were 35 patients with COPD and 35 control volunteers matched by age and gender. The characterization of the participants in the group with COPD was conducted by disease severity (FEV1) and dyspnea (MMRC scale). The body mass index was calculated for participants in both groups. The identification of the symptoms of dysphagia was achieved by applying a screening questionnaire for dysphagia. Participants with COPD had moderate symptoms (p<0,001) and mild symptoms (p<0,003) of dysphagia when compared to subjects without the disease. The factor analysis allowed grouping in factors the questions that had meanings in common, reducing the amount of study variables. It was determined that four factors totaled 63,5% of the variability of the sample: Factor I - related to pharyngeal function and airway protection; Factor II: related to esophageal function and history of pneumonia; Factor III: related to nutritional status; Factor IV: related to oral function. The most frequent symptoms of dysphagia presented by the participants with COPD were related to factors: pharyngeal function and airway protection (p<0,001); esophageal function and history of pneumonia (p<0,001); and nutritional status (p<0,001). The BMI correlated with FEV1 (r=0,567;p<0;001) and nutritional state (r= -0,046; p<0,008). Dyspnea correlated with pharyngeal function and airway protection (r=0,408;p=0,015) and with esophageal function and history of pneumonia (r= 0,397; p<0,015). Pharyngeal function and airway protection correlated with esophageal function and history of pneumonia (r= 0,531; p=0,001). Conclusion: Participants with COPD had symptoms of dysphagia when compared to control group.
