Sixteen children (mean age 1.9 years) admitted to hospital with viral croup were assigned randomly to either a high humidity atmosphere or room air. No other treatment was given. During the initial 12 h both groups of patients showed a similar rate of recovery as measured by pulse rate, respiration rate, transcutaneous oxygen (TcO2), transcutaneous carbon dioxide (TcCO2) and a clinical rating. No therapeutic benefit was demonstrated from the provision of a high humidity atmosphere. The widespread use of humidification in the management of croup requires reappraisal.
16名因病毒性喉炎入院的儿童（平均年龄1.9岁）被随机分配到高湿度环境或室内空气中。未给予其他治疗。在最初的12小时内，通过脉搏率、呼吸率、经皮氧分压（TcO2）、经皮二氧化碳分压（TcCO2）和临床评分来衡量，两组患者的恢复率相似。高湿度环境并未显示出治疗益处。在喉炎治疗中广泛使用加湿疗法需要重新评估。
