摘要: BACKGROUND: Inhaled hypertonic saline is used for bronchial challenge and sputum induction in patients with chronic obstructive pulmonary disease (COPD). We studied the effects of aerosol inhalation before each exercise session an 8-week rehabilitation program. METHODS: This was a double-blind randomized parallel controlled trial, conducted at outpatient clinic. Sixty-eight subjects COPD (mean age 67 6.5 y, percent predicted FEV1 47 21) were to inhale either 3% (34 subjects) or normal program that had 3 sessions per week. measured 6-min walk distance, dyspnea, quality life (with Medical Outcomes Study 36-item short-form health survey). RESULTS: After program, both groups’ mean distance significantly increased: from 195 92 mt o 251 97 m( P < .001) hypertonic-saline group, 237 93 441 121 m normal-saline group (P .001). The greater improvement than Dyspnea score improved 3.1 0.9 2.3 0.8 .01) 3.5 0.2 1.0 group. Quality also improved, except physical-functioning social aspect domains Adverse (cough bronchospasm) occurred 4 (12%) CONCLUSIONS: saline. Hypertonic associated adverse
