[corrected] To study the utility of chest physiotherapy by increased exhalation technique with assisted cough in the acute bronchiolite of the hospitalized new-born babys.


Double-blind clinical trial accomplished on 236 patients of age lower than 7 months and hospitalizad with diagnosis of acute bronchiolitis, first episode, in a pediatric department in Madrid.The patients were randomized in two groups: those who have received maneuvers of chest physiotherapy and those who have received maneuvers placebo. Only physiotherapist were aware of the allocation group of the infants. The days of hospitalization and the hours of oxygentherapy were used like result measurement.


From the totality of the studied children 57,6% received maneuvers of chest physiotherapy and 42,4% remaining received maneuvers placebo. In the group that received chest physiotherapy the average stay in the hospital was 4,56 days (95% confidence interval [CI] 4,36-6,06) and the average time of oxygentherapy was 49,98 (95% CI 43,64-67,13) hours opposite to 4,54 days (95%CI 3,81-5,73) and 53,53 hours (95% CI 48,03-81,40) respectively in the group that did not receive chest physiotherapy. In the patients with analytical print for VRS and that received chest physiotherapy less hours of oxygen therapy were needed 48,80 hours (95% CI 42,94-55,29) opposite to 56,68 hours (95% CI 55,46-65,52) respectively, being the only one turned out as per statistics significantly (P=.042).


Results show that chest physiotherapy has not been effective in reducing hospital stay or length of oxygentherapy in patients with acute bronchiolitis, but in the positive study of children with respiratory syncytial virus in nasopharyngeal aspirate showed a reduced need hours of oxygen. hours (P=.042).
