The use of an improper technique with metered-dose inhalers decreases the efficacy of the bronchodilators being administered. There is evidently a need for patients to watch a demonstration. Twenty-nine adult asthmatic patients from an allergy clinic were divided into three groups, each receiving a different form of instruction: an information sheet, personal instruction or a videotape presentation. Subsequently each patient was tested for correct use of the inhaler. There was no difference in mean scores for inhalation technique between the groups instructed in person and by videotape, but both were significantly better than the mean score of the group given only an information sheet. There was also no significant change in the scores at a follow-up test in the groups who saw the technique demonstrated. These results indicate the need for and value of the demonstration of proper technique with pressurized inhalers. A pharmacy-generated education system using videotape equipment or personal instruction by a pharmacist could readily solve the problem.
定量吸入器使用不当会降低所给予支气管扩张剂的疗效。显然患者需要观看演示。来自过敏诊所的29名成年哮喘患者被分为三组，每组接受不同形式的指导：信息单、个人指导或录像演示。随后对每位患者进行吸入器正确使用测试。亲自接受指导和通过录像接受指导的两组患者在吸入技术平均得分上没有差异，但两者均显著优于仅收到信息单的组的平均得分。观看技术演示的组在后续测试中的得分也没有显著变化。这些结果表明对加压吸入器正确技术演示的需求和价值。使用录像设备或药剂师进行个人指导的药房生成的教育系统可以很容易地解决这个问题。
