Respiratory Mechanics Effects of Flutter Valve in Bronchiectasis Patients

Status Completed

Clinical Trial Summary

Considering that respiratory physiotherapy lack scientific evidence to support its application in the treatment of several obstructive diseases, this investigation was designed to evaluate the hypothesis that Flutter Valve can improve the airway clearance of hypersecretive bronchiectasis patients.

Clinical Trial Description

The application of airway clearance techniques is considered an important component in the treatment of bronchiectasis patients (Van der Shans, 1997). For this purpose, a number of techniques has been introduced in the last decades. The Flutter Valve was initially proposed for the treatment of children with cystic fibrosis (CF) (Lindemann, 1992), but there is not enough evidence about its utilization in patients with bronchiectasis (Van der Shans & cols, 1999).

The effects of the Flutter Valve on respiratory mechanics of patients with bronchiectasis have been evaluated by forced spirometry (Pryor e cols, 1994; Gondor e cols, 1999; Thompson e cols, 2002). This approach however, does not allow the characterization of mucus transportation along the airways (Williams, 1994). The forced oscillation technique (FOT), a non-invasive alternative to characterize respiratory mechanics, allows the evaluation of respiratory mechanics at different frequencies without special maneuvers (Dubois e cols., 1956). According to eligibility criteria and in a randomized order, the patients were submitted to two protocols (control and Flutter Valve intervention), with one-week interval between them (washout). Respiratory mechanics and expectorated sputum volume were assessed before and after each intervention, in order to assess the Flutter Valve effect on tracheobronchial sputum removal. ;
