更换无螨床上用品对螨敏感哮喘儿童的影响：一项对照试验。

21名螨敏感性哮喘儿童参加了一项无螨寝具的交叉随机对照试验。每个孩子都有一个新的睡袋和枕头，为期一个月，每天两次的峰值流量读数与一个月内在孩子的普通床上获得的读数进行比较。其中17名儿童在无螨床上的平均峰值流量读数较高（p < 0.01）。然而，总体改善程度不大，试验结束时，大部分垫料中出现了一些螨虫。新的寝具可能对螨敏感性哮喘患者有帮助，但需要采取措施防止螨的定植。
Twenty-one children with mite-sensitive asthma took part in a crossover randomised controlled trial of mite-free bedding. Each child was issued with a new sleeping bag and pillow for a month, and twice-daily peak flow readings were compared with those obtained during a month in the child's ordinary bedding. Seventeen of the children had higher mean peak flow readings during the period in the mite-free bedding (p < 0.01). The overall improvement was only modest, however, and some mites had appeared in most of the bedding by the end of the trial. New bedding may be helpful to patients with mite-sensitive asthma, but methods are needed to prevent colonisation by mites.
