Loss of bronchoprotection to Salbutamol during sputum induction with hypertonic saline: implications for asthma therapy

BackgroundSputum induction with hypertonic saline in obstructive airway diseases is generally safe. However, saline induces bronchoconstriction in some patients despite pre-medication with Salbutamol. Our objectives were to investigate the predictors of failure of Salbutamol to protect against saline-induced-bronchoconstriction in patients with asthma and COPD and to evaluate implications for asthma therapy.MethodsRetrospective survey on a …
