ABSTRACT
<p><b>OBJECTIVE</b>The efficacy of bronchodilator in asthmatoid bronchitis remains controversial. This study was designed to investigate the effects of bronchodilators, salbutamo and ipraopium bromide, on the pulmonary function in young children with this disease.</p><p><b>METHODS</b>Pulmonary function tests were performed in 20 children with asthmatoid bronchitis (2 months-2.5 years of age) before and 30, 60, and 120 minutes after salbutamo and ipratropium bromide inhalation. The indexes of pulmonary function measured included tidal breathing flow volume (TBFV) loop, percent of tidal volume to peak tidal expiratory flow (%V-PF), terminal flows per peak expiratory flow (25/PF), peak tidal expiratory flow (PTEF), rate of mid-expiratory to mid-inspiratory flow (ME/MI), respiratory rate (RR) and tidal volume per kilogram (TV/kg).</p><p><b>RESULTS</b>Before drug inhalation, the descending branch of the TBFV loop was depressed. The PTEF shifted forward and %V-PF (0.19 +/- 0.04) and 25/PF (0.42 +/- 0.11) decreased. These changes did not improve and the remaining indexes, RR, ME/MI and TV/kg, 30, 60, and 120 minutes after drug inhalation also remained similar to before inhalation.</p><p><b>CONCLUSIONS</b>Salbutamo and ipratropium bromide inhalation did not improve the airway resistance and ventilation function in children with asthmatoid bronchitis. This suggests that the efficacy of bronchodilator in the treatment of this disease is doubtful.</p>

Objective To study the clinic effects and safety of budesonide suspension combined with tubertaline solution for nebulization therapy on infantile asthma.Methods Seventy-five cases with asthma were divided into 3 groups randomly,double-blinded and controlled,each group having 25 cases.Group A inhaling tubertaline solution(bricanyl),while group B inhaling pulmicort respules combined with bricanyl,group C inhaling budesonide suspension(pulmicort respules)only.Results In group A,16 cases was cure,3 cases was markedly improved,6 cases was failure,the total efficacy rate was 76 percent.In group B,22 cases was cure,2 cases was markedly improved,1 case failed,the total efficacy rate was 96 percent.While in group C,14 cases was cure,4 cases was markedly improved,7 cases failed,the total efficacy rate was 72 percent.The difference of efficacy rate between group A and group B was significant(P0.05).Conclusion Pulmicort respules combined with bricanyl for nebulising inhalation is effective and safety on infantile asthma and its effect is better than inhaling bude-sonide or tubertaline only.
