IN RECENT years inhalaticn therapy has achieved ever increasing importance in maintaining respiratory function, owing mainly to the pioneering efforts of Barach, Segal and their co-workers in this field. With the introduction of administration of antibiotic substances by inhalation as an aerosol the scope of this type of therapy was broadened considerably.
The efficacy of penicillin aerosol therapy and its physiologic rationale have been well established.1 For many conditions occurring with greatest frequency in the pediatric age group aerosol penicillin is definitely indicated. However, the application of inhalation therapy in pediatric practice has several limitations. These are due chiefly to the fact that the most satisfactory methods at present are designed for adults and are not easily adaptable to use for persons in the younger age groups, since co-operation of the patient is not possible. It therefore becomes necessary to devise new methods which are adaptable to pediatric practice
