PURPOSE: In the patients with bronchiectasis, it is of great importance to remove the secretions in controlling the symptoms, preventing exacerbations, maintaining airway patency, and improving quality of life. Postural drainage is the best known non-pharmacological conventional therapy. Additionally, the active cycle of breathing techniques (ACPRC) are also used for this purpose. VEST™ device generating high-frequency chest wall compression is also used for mobilization of mucus secretions in the patients with bronchiectasis. The present study aimed to investigate efficiency of VEST™ application added to postural drainage. Primary end-point was amount of sputum discharge and the secondary end-points were quality of life, dyspnea score, CRP level, and hypoxia.

METHODS: The present study included 15 patients above 18 years old with bronchiectasis who were admitted to Department of Pulmonary Medicine of Hospital of Celal Bayar University. The patients were randomly assigned in two treatment groups. In the first group, 8 patients received high-frequency chest wall oscillation using VEST™ and pulmonary drainage (PD) for 20 minutes three times daily for 5 days. In the second group, 7 patients received ACPRC and PD for 20 minutes 3 times daily for 5 days. The patients were evaluated using short-form 36 which was a scale for overall quality of life and modified dyspnea scale of medical research council (MMRC) at the baseline and at the end of the study. CRP levels, arterial blood gases and daily amount of sputum production were recorded before and after application of 5 days.

RESULTS: There was no statistically significant difference between two groups in age, sex, occupation, co-morbidity, smoking status, fever, and sputum production. In both groups, however, an increase was found in amount of sputum production and pO2 value at days 2 and 3 with the difference being more prominent in the VEST™ group.

CONCLUSIONS: When the VEST™ device was used with postural drainage, it was observed that daily amount of sputum discharge increased more, the hypoxia was improved, and positive changes in quality of life occurred although the difference was not statistically significant. Preliminary results of the current study supports the fact that adding VEST™ to the conventional treatment would provide positive contribution in the patients with bronchiectasis by increasing amount of sputum production.

CLINICAL IMPLICATIONS: Our data supports the fact that adding VEST™ to the conventional treatment would provide positive contribution in the patients with bronchiectasis by increasing amount of sputum production.
