To study the correlation between the bronchial dilation test (BDT) and asthma control level in children with asthma.
A total of 153 children with asthma, aged 5-14 years, who attended the outpatient service from March 2016 to March 2018 were enrolled. According to the presence or absence of atopic constitution, they were divided into an allergic group with 79 children and a non-allergic group with 74 children. The correlation between BDT and Childhood Asthma Control Test (C-ACT) scores was analyzed for both groups.
All basic pulmonary function parameters were positively correlated with C-ACT scores in the non-allergic group ( < 0.05). Except the forced vital capacity, peak expiratory flow and maximal expiratory flow at 25% vital capacity in percent predicted values, the other pulmonary function parameters were positively correlated with C-ACT scores in the allergic group ( < 0.05). The improvement rates of all BDT parameters (except maximal expiratory flow at 25% vital capacity in the allergic group and maximal expiratory flow at 50% vital capacity in the non-allergic group) were negatively correlated with C-ACT scores in the two groups ( < 0.05).
The improvement rate of BDT is well correlated with C-ACT scores in children with asthma, suggesting that BDT can be used as an index for predicting asthma control level.
研究支气管舒张试验（BDT）与哮喘患儿哮喘控制水平之间的相关性。
选取2016年3月至2018年3月在门诊就诊的153例5 - 14岁哮喘患儿。根据是否有特应性体质，将其分为过敏组79例和非过敏组74例。分析两组中BDT与儿童哮喘控制测试（C - ACT）评分之间的相关性。
非过敏组所有基本肺功能参数与C - ACT评分呈正相关（<0.05）。过敏组除用力肺活量、呼气峰值流速及25%肺活量时的最大呼气流量占预计值百分比外，其他肺功能参数与C - ACT评分呈正相关（<0.05）。两组中所有BDT参数的改善率（过敏组中25%肺活量时的最大呼气流量及非过敏组中50%肺活量时的最大呼气流量除外）与C - ACT评分呈负相关（<0.05）。
BDT改善率与哮喘患儿C - ACT评分密切相关，提示BDT可作为预测哮喘控制水平的指标。
