RESUMO
Objective To discuss Si tactic of breathing exercises on the rehabilitation of lung function, dyspnea, distance of 6-minute walk distance (6MWD), respiratory muscle endurance and quality of life in stable patients with chronic obstructive pulmonary disease (COPD). Methods 63 patients with COPD were divided into experimental group with 31 cases and control group with 32 cases according to random digital table method. The experimental group were given routine treatment and nursing care, take Si tactic of breathing exercises. The control group were given routine treatment and nursing care only. Both groups were given treatment for 4 months. The indexes of lung function (FEV1, FEV1%, FEV1/FVC), scores of the Modified Medical Research Council Scale (MMRC), 6MWD, scores of Saint-George′s Respiratory Questionnaire (SGRQ), maximal voluntary ventilation (MVV) changes before and after the therapy were measured. Results After intervention, the lung function as measured by FEV1, MVV, 6MWD showed a significant improvement in the experimental group, and was higher than that in the control group[(1.42±0.43) L vs.(1.22±0.32) L and(1.21±0.45) L,(52.39±14.21) L vs.(47.20±14.59) L and (43.65±11.89) L, (288.36±71.70) m vs.(244.42±71.50) m and (250.56 ±79.25) m, P<0.05]; MMRC scores, SGRQ scores, activities and daily life part score were lower after intervention and was lower than that in the control group [(2.63 ±1.00) points vs. (3.21 ±0.92) points and (3.14±1.12) points, (44.38±5.23) points vs. (54.74±5.73) points and (52.87±5.49) points, (41.25± 6.03) pints vs.(66.48±6.38) points and (64.13±5.34) points, (28.00±7.34) points vs. (44.87±4.86) points and (42.31 ±9.12) points, P<0.05]. Conclusions For COPD patients in stable stage, Si tactic of breathing exercises can improve the pulmonary function and alleviate dyspnea, enhance exercise endurance and respiratory endurance, thereby improve the quality of life of patients, so this is one of the method for comprehensive pulmonary rehabilitation in the future.
