目的:分析硫酸镁联合沙丁胺醇雾化吸入治疗毛细支气管炎疗效及特应性体质对硫酸镁治疗敏感度的区别,并对治疗方法进行安全性评价.方法:本研究自2021年1月-2021年8月在滨州市中心医院进行研究人群招募.本研究共纳入100名符合条件的研究对象.将100名研究对象随机分为2组(对照组和观察组),每组50例.对照组接受常规治疗,观察组增加硫酸镁联合沙丁胺醇雾化吸入治疗.结果:对于治疗以后,两组的肺功能改善情况进行比较分析,发现观察组FEV1、FVC和PEF等指标均高于对照组,差异具有统计学意义(P＜0.05).两“,”Objective:To analyze the efficacy of magnesium sulfate combined with salbutamol nebulized inhalation in the treatment of bronchiolitis and the sensitivity of atopic physique to magnesium sulfate treatment,and to evaluate the safety of the treatment method. Methods:The study was recruited in Binzhou Central Hospital from January 2021 to August 2021. A total of 100 eligible research subjects were included in this study. 100 research subjects were randomly divided into 2 groups (control group and observation group),with 50 cases in each group. The control group received conventional treatment,and the observation group added magnesium sulfate combined with albuterol nebulized inhalation therapy. Results:After treatment,the lung function improvement of the two groups was compared and analyzed. It was found that the FEV1,FVC and PEF indicators of the observation group were higher than those of the control group,and the difference was statistically significant (P＜0.05). A comparative analysis of the improvement of symptoms between the two groups showed that the cough improvement time,wheeze improvement time,shortness of breath improvement time,hospitalization time and other indicators of the observation group were lower than those of the control group,and the difference was statistically significant (P＜0.05). Conclusion:Salbutamol combined with magnesium sulfate atomized inhalation has a significant effect on the treatment of bronchial asthma,which can effectively shorten the rehabilitation process,and no adverse reactions occurred during the treatment.
