目的 探究综合排痰辅助治疗小儿哮喘样支气管炎的效果及对患儿气道高反应性的影响。方法 随机选取2015年5 月-2017年1月我院门诊收治的哮喘样支气管炎患儿80例为研究对象，按治疗方式不同将其分为观察组(n=40)和对照 组(n=40)，对照组患儿采用常规治疗和护理。观察组患儿在对照组基础上联合综合排痰辅助治疗，比较两组临床疗 效、炎症因子水平和治疗前后肺功能指标变化、PC20FEV1(FEV1下降20%需要激发药物的浓度)。结果 观察组疗效总有 效率(92.5%)显著高于对照组(72.5%)，治疗后观察组炎症因子水平显著低于对照组，观察组治疗后肺功能指标和 PC20FEV1水平显著高于对照组，差异具有统计学意义(P<0.05)。结论 综合排痰辅助治疗小儿哮喘样支气管炎能显著 减轻患儿气道炎症反应，改善肺功能，降低气道高反应性，值得推广。

Objective To investigate the effect of comprehensive expectoration adjunctive therapy on asthmatic bronchitis and its influence on airway hyperreactivity in children. Methods From May 2015 to Jan. 2017, 80 cases of children with asthmatic bronchitis in our hospital were selected as the research objects, and they were divided into observation group (n=40) and control group (n=40) according to their different treatment methods. The control group was given routine treatment and nursing, and the observation group was given additional comprehensive expectoration adjunctive therapy on the basis of the control group. The curative effects, inflammatory factors levels and pulmonary function changes before and after treatment, PC20FEV1 (FEV1 down 20% required the concentration of drug to be stimulated) in the two groups were compared. Results The total effective rate in the observation group was (92.5%) which was significantly higher than that in the control group (72.5%), after treatment, the levels of inflammatory factors in the observation group were significantly lower than those in the control group; the lung function indexes and the level of PC20FEV1 in the observation group after treatment were significantly higher than those in the control group, the difference was statistically significant (P<0.05). Conclusion Comprehensive expectoration adjuvant therapy can significantly not only reduce airway inflammation and airway hyperreactivity, but also improve lung function for children with asthmatic bronchitis. Thus, it is worthy of promotion.
