Resumo
The Chronic Obstructive Pulmonary Disease (COPD) is a preventable and treatable
respiratory disease, which is characterized by the presence of chronic airflow
obstruction which is not completely reversible after the bronchodilator use. The
airflow limitation is usually progressive and it is associated with an abnormal
inflammatory response of the lungs to inhaled particles or toxic gases, caused
primarily by smoking. It is one of the mainly causes of morbidity and mortality in the
whole world. The deterioration of the lung function throughout the time, associated
with the systemic effects which lead to a permanent disability, is evidenced by
fatigue, exercise intolerance and consequent worsening of the fitness which limits the
daily activities, with reduced on the quality of life. Besides that, dyspnea contributes
significantly to reduced a worse prognosis of the disease. The pulmonary
rehabilitation, if focused on physical exercises, as documented in literature, has been
considered the most effective alternative to minimize the deleterious effects of
deconditioning in these patients. Objective: evaluate the program pulmonary
rehabilitaton on functional capacity, on dyspnea index and on its impact on the quality
of life of the patients with COPD. Methodology: It is test clinic not control which was
approved by the HC-UFG ethics committee on research. Seventeen patients, who
participated in the Pulmonary Rehabilitation Program, with COPD were evaluated at
the time of the admission to the program and also after 20 training sessions. The
patients with musculoskeletal diseases who limited walking or were showing
significant cognitive impairment were excluded. The analyzed variables were age,
sex, degree of pulmonary obstruction (VEF1), body mass index (BMI), respiratory
muscle strength, BODE index of mortality, quality of life by the St. George's
Respiratory Questionnaire (SGRQ), the impact of dyspnea during the daily activities
analyzed in the scale assessed by the London Chest Activity of Daily Living (LCADL),
dyspnea index (MRC) and the distance walked during the six-minute walk (6minWD).
Statistical Analysis: To test the normality of these data, the Kolgomorov-Smirnov
test was used; to compare the variables pareades before and after the pulmonary
rehabilitation the Student t test was used and to value the association between the
variables was used the coefficient of correlation of Pearson. RESULTS: Were
evaluated 17 patients, mean age of 72.46 ± 5.84 years old, FEV1% pred. 48.54 +
11.14, BMI 23/89 +2.80 kg/m2. There was a improvement in the test six-minute walk
(p = 0.001) and there was an improvement in the inspiratory muscle strength (p=
0.042), there was reduced of dyspnea (p = 0.002), the impact of dyspnea during
activities of daily living acitvities (p = 0.001) and a improvement in the quality of life (p
= 0.001). Conclusion: The program of pulmonary rehabilitation promoted a
improvement in functional capacity, reducing the dyspnea and also in the quality of
life.
