The use of metered dose inhaler (MDI) is key in the treatment of asthma; its effectiveness is related to proper technique.
The purpose of this study is to evaluate the use of the technique of metered dose inhalers for the parents or guardians of school children with asthma.
In this cross-sectional study, we used a sample of 221 individual caregivers (parent or guardian) of asthmatic children from 5 to 12 years old, who use MDI. We designed a validated questionnaire consisting of 27 items which addressed the handling of inhaler technique. Descriptive statistics was used.
Caregivers were rated as "good technique" in 41 fathers (18.6%), 77 mothers (34.8%) and 9 tutors (4.1%), and with a "regular technique" 32 fathers (14.5%), 48 mothers (21.2%) and 14 guardians (6.3%). Asthmatic children aged 9 were rated as with "good technique" in 24 (10.9%). According to gender, we found a "good technique" in 80 boys (36.2%) and 47 girls (21.3%) and with a "regular technique" in 59 boys (26.7%) and 35 girls (15.8%), P 0.0973, RP 0.9. We found with a "regular technique" mainly those asthmatic children diagnosed at ages between 1 to 3 years.
Most of the participants had a good technical qualification; however major mistakes were made at key points in the performance of it.
定量吸入器（MDI）的使用是哮喘治疗的关键；其有效性与正确的使用技术相关。
本研究旨在评估哮喘学龄儿童的父母或监护人使用定量吸入器的技术情况。
在这项横断面研究中，我们选取了221名5至12岁使用MDI的哮喘儿童的个体照料者（父母或监护人）作为样本。我们设计了一份经过验证的包含27个项目的问卷，内容涉及吸入器技术的操作。采用描述性统计方法。
41名父亲（18.6%）、77名母亲（34.8%）和9名监护人（4.1%）的照料技术被评为“良好”，32名父亲（14.5%）、48名母亲（21.2%）和14名监护人（6.3%）的技术被评为“一般”。9岁的哮喘儿童中有24名（10.9%）的技术被评为“良好”。按性别划分，我们发现80名男孩（36.2%）和47名女孩（21.3%）的技术为“良好”，59名男孩（26.7%）和35名女孩（15.8%）的技术为“一般”，P = 0.0973，RP = 0.9。我们发现主要是那些在1至3岁被诊断出哮喘的儿童技术为“一般”。
大多数参与者具备良好技术水平；然而在操作的关键点上存在重大失误。
