Abstract :
[Background]Our aim was to investigate the acute effect of inhaled NaCl 5% on spirometry indices in patients aged over six years with cystic fibrosis (CF).[Methods]44 children over 6 years of age with CF took part in this study. Spirometry indices were measured. After receiving two puffs of salbutamol spray, the children were administered with 5 ml NaCl 5% by a medical compressed air system using a nebulizer kit and immediately a spirometric test was taken again. Spirometry results were recorded and the data were analyzed by SPSS v.18.[Results]The percentages of the annual decline of forced expiratory volume in one second (FEV1) were 10.12 ± 31.28, 7.26 ± 17.10, and 13.8 ± 21.7 in children aged 6 - 8 years, 9 - 12 years, and over 13 years, respectively. There were significant differences in FVC, FEV1/FVC, MEF50, MEF75, MMEF25/27 before and after hypertonic NaCl 5% inhalation (P < 0.05). A significant decline in FEV1 was observed only in 2% of the children.[Conclusions]Patients with CF exhibited a suitable response to acute inhalation of hypertonic NaCl 5%.
