Study design (if review, criteria of inclusion for studies)
RCT crossover
Participants
20 patients with cystic fibrosis
Interventions
On three separate occasions, pulmonary function was tested preceding and following treatments consisting of one of the above three aerosol solutions followed by bronchial drainage. The order of solutions used was random and each subject received one treatment with each solution.
Outcome measures
pulmonary function scores
Main results
The greatest overall improvement in function was seen with the bronchodilator and bronchial drainage. The combination of the bronchodilator/mucolytic agents and bronchial drainage was the next most effective technique. The mucolytic agent, when used alone with bronchial drainage, decreased function. Comparison of the pulmonary function scores indicated a significant difference among the three treatments.
