A comparison of bronchial drainage treatments in cystic fibrosis

Evaluation of a novel technique in airway clearance therapy – Specific Cough Technique (SCT) in cystic fibrosis: A pilot study of a series of N-of-1 randomised controlled trials

“…While some studies found no difference in the ratio of dry to wet sputum weight, 21 and no significant difference in wet or dry sputum weight between treatment groups and placebo, 28 other studies have found a significant difference between treatments when considering both wet and dry weight. 30 Although a standardised protocol was used in this study, the lack of sufficient recoding of total coughs in the interventions, as spontaneous coughs can influence sputum production, may have affected sputum weight.…”

High-Frequency Chest Wall Compression Therapy in Neurologically Impaired Children

“…It is possible that HFCWC benefits children with cerebral palsy and neurological impairment by promoting the mobilization of tracheobronchial secretions and facilitating mucociliary clearance, as it does in children with cystic fibrosis. 27 Impaired cough is a major contributor to respiratory morbidity. 2,12 Cough assistance benefits and is now recommended for children with congenital muscle dystrophies.…”

A Comparison of the Therapeutic Effectiveness of and Preference for Postural Drainage and Percussion, Intrapulmonary Percussive Ventilation, and High-Frequency Chest Wall Compression in Hospitalized Cystic Fibrosis Patients

“…Recent studies suggest that IPV is as effective as PD&P and that HFCWC is as effective as or possibly more effective than PD&P. [5][6][7][8][9] However, as far as we know, no previous study directly compared PD&P, IPV, and HFCWC in a single group of CF patients. Natale et al, 5 in a crossover study of 9 in-patients, compared sputum volume expectorated using PD&P and IPV.…”
