Bronchiectasis Adult
Conditions
Brief summary
No study have evaluated the efficacy and safety of airway clearance therapy (ACT) and bronchoalveolar lavage (BAL) under bronchoscope for bronchiectasis. This study aimed to evaluate the clinical efficacy and safety of tran-bronchoscopy airway clearance and bronchoalveolar lavage in the treatment of moderate to severe bronchiectasis with acute exacerbation:A randomized, prospective cohort study.
Detailed description
The aim of this study was to evaluate the efficacy and safety of ACT combined with BAL for bronchiectasis patients with acute exacerbation through the whole study process, which will provide a high quality of evidence-based strategies for the treatment, revision and optimization of international and domestic clinical guidelines for bronchiectasis. All the participants will be required to check the various efficacy and safety indicators.
