Ensayo clínico aleatorizado de técnicas de aclaramiento mucociliar en niños con bronquiectasias sin fibrosis quística

Abstract

ObjectiveTo evaluate effectiveness of manual expiratory pressure and expiratory flow increase (EFI) combined with mechanical insufflation-exsufflation (MI-E) and assisted coughing (AC) versus active cycle of breathing techniques (ACBT) in stable bronchiectasis children without cystic fibrosis (CF). Material and methodsRandomized clinical trial with 2 groups of 6 children (age 8.1±1.3) who received of respiratory physiotherapy (RP) sessions twice a month. The main endpoints studied are: weight of sputum collected after each session of RP and lung function measurements at baseline and 12 months, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), peak expiratory flow between 25%-75% of FVC (FEF25-75%). We also evaluated the number of visits to emergency department, infective exacerbations and the impact of cough on quality of life with the Leicester Cough Questionnaire (LCQ), at the beginning and the end of study. ResultsThe weight of sputum and FEF25-75% increase significantly with manual expiratory pressure, EFI combined with MI-E and AC versus ACBT in our sample. There are no significant differences in FEV1 and FVC. Number of exacerbations decreased in both groups compared to the previous year (without CP treatment), and total score of the LCQ. ConclusionSlow manual expiratory pressure, EFI combined with MI-E and AC for airway permeabilization in children with non-CF bronchiectasis produce significant benefits compared to ACBT.
