Use of a special inhaler attachment in asthmatic children.

Asthmatics often find difficulties in using an aerosol inhaler correctly as they are unable to co-ordinate the release of a bolus of drug to coincide with an inspiratory effort. This is especially the case with children. The addition of a special attachment to an ordinary inhaler overcame this problem. Twelve asthmatic children produced significantly better PEFR measurements when 0.25 mg terbutaline sulphate was administered via an inhaler with the attachment than when an ordinary inhaler was used alone.
