Sleep pattern in patients with Chronic Obstructive Pulmonary Disease and correlation among gasometric, spirometric, and polysomnographic variables

OBJECTIVE: There are few studies on chronic obstructive pulmonary disease (COPD) establishing differences between the functional parameters of the disease and sleep variables. The aim of the study was to describe the sleep pattern of these patients and to correlate spirometric, gasometric and polyso...

The aim of the study was to describe the sleep pattern of these patients and to correlate spirometric, gasometric and polysomnographic variables. METHODS: Transversal study using COPD patients submitted to spirometry, arterial gasometry, and polysomnography. RESULTS: 21 male patients were studied with average age = 67 ± 9; 7 ± 4 average points in the Epworth sleepiness scale, average Tiffenau's index (FEV1/FVC) = 54 ± 13.0%, average PaO2 = 68 ± 11 mmHg, average PaCO2 = 37 ± 6 mmHg. Sleep efficiency decreased (65 ± 16%) with the reduction of slow wave sleep (8 ± 9%) and rapid eye movement (REM) sleep (15 ± 8%). Average T90 was 43 ± 41%. Average apnea-hypopnea index (AHI) = 3 ± 5/h, where two patients (9.5%) presented obstructive sleep apnea. A significant correlation was observed between PaO2 and T90 (p < 0.01), PaCO2 and T90 (p < 0.05), and AHI and the cardiac rate during REM (p < 0.01). A higher number of arousals and stage change was observed. There was no linear correlation between spirometric and polysomnographic variables. CONCLUSION: Poor sleep quality of these patients was characterized by low sleep efficiency, high number of awakenings and shift of stages. There were no correlations between the spirometric and polysomnographic variables. OBJETIVOS: Pouco se investigou o sono de pacientes portadores de doença pulmonar obstrutiva crônica (DPOC) estabelecendo comparações entre parâmetros funcionais e polissonográficos. Este estudo objetiva descrever o sono desses indivíduos e correlacionar variáveis espirométricas, gasométricas e polissonográficas. MÉTODOS: Estudo transversal em portadores de DPOC, avaliando espirometria, gasometria arterial e polissonografia. Resultados: Avaliados 21 pacientes masculinos com idade = 67 &plusmn; 9 anos, na escala de sonolência de Epworth (ESE) = 7 &plusmn; 4 pontos, índice de Tiffenau (VEF1/CVF) = 54 &plusmn; 13,0%, PaO2 = 68 &plusmn; 11mmHg, PaCO2 = 37 &plusmn; 6mmHg. A eficiência do sono foi diminuída (65 &plusmn; 16%) com redução do sono de ondas lentas (8 &plusmn; 9%) e da fase do sono de movimento rápido dos olhos (REM) (15 &plusmn; 8%). T90 médio = 43 &plusmn; 41% . Índice de apnéia-hipopnéia médio = 2,9 &plusmn; 5,2/h, sendo que dois pacientes (9,5%) apresentaram apnéia obstrutiva do sono. Observou-se correlação significativa entre PaO2 e T90 (p < 0,01), PaCO2 e T90 (p < 0,05) e IAH e freqüência cardíaca durante o REM (p < 0,01). Foi também observado elevado número de despertares e de mudanças de estágio. Não houve correlações lineares entre variáveis espirométricas e polissonográficas. Conclusões: Observou-se má qualidade de sono nesses pacientes, caracterizada por baixa eficiência do sono e elevado número de despertares e mudanças de estágios. Não foram observadas correlações entre variáveis espirométricas e polissonográficas. 2017-12-07T04:37:46Z 2017-12-07T04:37:46Z 2003 Artigo J.
