THE INHIBITORY EFFECT OF BOOTH WITH ELECTRIC AIR CLEANER IN INSTITUTIONALIZED ASTHMATIC CHILDREN, EXACERBATED DURING HOME STAY

The inhibitory effect of booth with electric air cleaner (Mite-Free Booth) on acute asthma attacks was evaluated in seventeen children with bronchial asthma (atopic type) receiving institutional therapy by multi-center double blind crossover study.1. The numbers of house dust mite in their bedroom and floor were 1095/g and 1050/g, on an average respectively, and mite allergen was caught by filter in Mite-Free Booth.2. In group using Mite-Free Booth, clinical usefulness was observed in 52.9% of patients, while those was 23.5% in control group.3. There were no exacerbation evaluated by the number of asthma attacks and pulmonary function during home stay in group using Mite-Free Booth, although those was significantly exacerbated in control group.These results suggest that Mite-Free Booth is useful equipment for the management of atopic bronchial asthma.
