The most common treatment for asthma is transferring the drug into the lungs by inhaler devices. Besides, correct use of inhaled medication is required for effectiveness of pharmacotherapy. Thus, it is necessary to train the patients how to use Metered Dose Inhaler (MDI). This study aimed to determine the effect of training about MDI usage with or without spacer on maximum expiratory flow rate and inhaler usage skills in asthmatic patients.
This randomized clinical trial was conducted on 90 asthmatic patients who were randomly divided into inhalation technique group with spacer, inhalation technique group without spacer, and a control group. Then, the Peak Expiratory Flow Rate (PEFR) was measured using a peak flow meter, as a basic test. In addition, the patients' functional skills of inhalation technique were assessed using two checklists. Afterwards, 3 sessions of training were arranged for both groups. PEFR and the ability to use the MDI were evaluated immediately and 1 month after the intervention. Finally, the data were entered into the SPSS statistical software (v. 18) and analyzed using independent t-test and repeated measures ANOVA.
After the intervention, MDI usage skills improved in the two intervention groups compared to the control group (P<0.001). In addition, a significant difference was found between the intervention groups and the control group regarding the mean of PEFR after the intervention (P<0.001). However, no significant difference was observed between the two intervention groups (P=0.556).
According to the results, providing appropriate training for asthmatic patients increased MDI usage skills, and both methods of inhalation (with or without spacer) could improve the PEFR among the patients.

哮喘最常见的治疗方法是通过吸入装置将药物输送到肺部。此外，药物治疗的有效性需要正确使用吸入药物。因此，有必要对患者进行如何使用定量气雾剂（MDI）的培训。本研究旨在确定有或无储雾罐的MDI使用培训对哮喘患者最大呼气流量和吸入器使用技能的影响。
本随机临床试验对90例哮喘患者进行，这些患者被随机分为有储雾罐的吸入技术组、无储雾罐的吸入技术组和对照组。然后，使用峰流速仪测量呼气峰值流速（PEFR），作为基础测试。此外，使用两份检查表评估患者吸入技术的功能技能。之后，为两组安排了3次培训课程。在干预后立即和干预后1个月评估PEFR和使用MDI的能力。最后，将数据输入SPSS统计软件（v.18），并使用独立t检验和重复测量方差分析进行分析。
干预后，与对照组相比，两个干预组的MDI使用技能有所提高（P<0.001）。此外，干预后干预组和对照组在PEFR平均值方面存在显著差异（P<0.001）。然而，两个干预组之间未观察到显著差异（P=0.556）。
根据结果，为哮喘患者提供适当培训可提高MDI使用技能，两种吸入方法（有或无储雾罐）均可改善患者的PEFR。
