目的研究控制尘螨孳生对螨过敏性哮喘（ＤＭＳＡ）患者生存质量（ＱＯＬ）的影响。方法对４３例ＤＭＳＡ患者卧室中床垫、被褥、沙发和枕头等部位，每季度采集积尘一次，计尘螨数。一年后随机分为控螨组（Ｔ组）和对照组（ＮＴ组）。Ｔ组采用加强通风、降低温湿度、洗涤吸尘、暴晒物件和改变室内陈设等综合物理措施。ＮＴ组未作特殊处理，每季度作ＱＯＬ评估一次。结果Ｔ组尘螨密度明显降低、ＱＯＬ评分显著改善，（Ｐ＜０．０５）。而ＮＴ组尘螨密度和ＱＯＬ评分均无明显变化。结论通过综合物理措施控制尘螨孳生可改善ＤＭＳＡ患者ＱＯＬ。
Objective To study the effect of controlling dust mite breeding on quality of life (QOL) in patients with mite allergic asthma (DMSA). Methods A total of 43 cases of DMSA patients in the bedroom, mattresses, bedding, sofas and pillows and other parts of the collection of dust every quarter, count the number of dust mites. One year later were randomly divided into control mite group (T group) and control group (NT group). In Group T, comprehensive physical measures such as strengthening ventilation, reducing temperature and humidity, cleaning dust, exposing objects and changing indoor furnishings were adopted. NT group without special treatment, QOL quarterly assessment. Results The density of dust mite in T group was significantly decreased, QOL score was significantly improved (P <0.05). There was no significant change in the density and QOL scores of dust mite in NT group. Conclusion The QOL of DMSA patients can be improved by comprehensive physical measures to control dust mite breeding.
