The effectiveness of antiasthmatic therapy with metered-dose inhalers (MDIs) is usually limited by defective inhalational technique. This study surveyed the MDI inhalation performance and knowledge of 100 physicians whose performance (demarcated into six stages) and knowledge scores correlated (r = 0.33, p < 0.001). Inhalation performance scores for shaking the canister, full expiration prior to using the MDI, breath holding thereafter, and positioning of the mouth-piece correlated with their corresponding knowledge scores (p < or = 0.02). Training of physicians entailing actual instruction and supervision of inhalational maneuvers may enhance the ability of doctors to use MDIs and facilitate better patient supervision.
定量吸入器（MDIs）抗哮喘治疗的有效性通常受到吸入技术不佳的限制。本研究调查了100名医生的MDI吸入操作和知识情况，其操作表现（分为六个阶段）与知识得分相关（r = 0.33，p < 0.001）。罐身摇晃、使用MDI前的完全呼气、之后的屏气以及吸嘴位置的吸入操作得分与相应的知识得分相关（p≤0.02）。对医生进行涉及吸入动作实际指导和监督的培训，可能会提高医生使用MDIs的能力，并有助于更好地对患者进行监督。
