Abstract INTRODUCTION: Effective Airway Clearance Techniques (ACT) is the key step in the management of Bronchiectasis. The aim of this study was to evaluate the efficacy of 3% Hypertonic Saline (HS) pre-medication in ACT in children with non Cystic Fibrosis (non-CF) bronchiectasis. METHODS: Five to 15 year old children with non-CF bronchiectasis were randomized either to receive 200µg of inhaled salbutamol followed by hypertonic saline nebulization (test) or only 200µg of inhaled salbutamol, prior to chest physiotherapy which is the conventional ACT (controls) for 8 weeks. After completion of first phase both groups went through one month washout period, before being crossed over to the opposite arms in the second phase. Spirometric parameters were recorded at the end of each phase. RESULTS: Fifty two children completed the study. Baseline characteristics of the two groups were similar. A significantly higher mean improvement was seen in predicted Forced Expiratory Volume in one second(FEV1) in the HS arm during phase 1 [HS=14.15±5.50 vs. conventional =5.04±5.55, p=0.001] and phase II [HS =10.81±5.51 vs. conventional =3.54 ±5.13, p=0.001]. HS arm showed a significantly higher mean improvement in predicted Forced Vital Capacity(FVC) in phase I[HS=13.77±5.73 vs. conventional= 7.54±4.90, p=0.001] and phase II, [HS=9.42±7.00 vs. conventional =4.42±4.00, p=0.003). Mean number of exacerbations experienced by a single child during phase I (2 months) were significantly less (p=0,001) in HS group compared to that of conventional group. CONCLUSIONS: Incorporating HS nebulization into ACT is an effective strategy to improve dynamic lung volumes and morbidity in children with non-CF bronchiectasis.
