Stridor in childhood asthma.

Three asthmatic children are reported with shortness of breath due to stridor. The stridor was preceded by a deterioration in asthma control necessitating the introduction or increased dosage of a pressurized beclomethasone inhaler. The stridor mimicked asthmatic symptoms and was only differentiated by auscultation directly over the neck and by response to nebulized adrenaline. One child had a laryngeal foreign body which probably gained entry via a pressurized inhaler.
