[目的 ]观察布地奈德气雾剂防治小儿哮喘的疗效。 [方法 ]对 48例中、重度哮喘患儿缓解期用布地奈德气雾剂吸入治疗 2 8例 ,传统法治疗 2 0例为对照。[结果 ]治疗后 3个月随诊观察 ,治疗组 2 8例均为首次用药 ,其中有 2 0例 4～ 7岁儿童采用吸入雾化器 ,用药后 ,临床控制 13例 ,显效 10例 ,有效 5例 ,无效 1例。疗效明显高于对照组 (χ2 =10 .39,P<0 .0 5 )。治疗前后均比较两组 PEFR值 ,治疗组治疗后 PEFR值 170 .18± 6 3.43L /min,较对照组 135 .5± 45 .79L /min显著提高 (t=2 .0 85 ,P<0 .0 5 ) ,疗效显著优于对照组。[结论 ]小儿哮喘缓解期持续吸入布地奈德气雾剂 ,可有效防治哮喘的发作。 [Objective] To observe the efficacy of budesonide aerosol in preventing and treating pediatric asthma. [Method] Twenty-eight cases of moderate and severe asthma children were treated with inhalation of budesonide aerosol and 20 cases of traditional method were used as controls. [Results] 28 months after treatment, 28 cases were treated for the first time, 20 cases of children aged 4 to 7 years using inhalation nebulizer, after treatment, clinical control in 13 cases, markedly effective in 10 cases, Effective in 5 cases, 1 case of invalid. The curative effect was obviously higher than that of the control group (χ2 = 10.39, P <0.05). The PEFR values ​​of the two groups before and after treatment were compared. The PEFR value of the treatment group after treatment was 170.18 ± 6.33L / min, which was significantly higher than that of the control group 135.5 ± 45.79L / min (t = 2.855, P0.01 .0 5), the effect was significantly better than the control group. [Conclusion] Sustained inhalation of budesonide aerosol in pediatric asthma remission can effectively prevent and treat the onset of asthma.
