摘要

背景:我们的目的是比较分子水(汽化加湿器)和颗粒水(气管喷雾)吸入气管造口患者的自主呼吸。方法:我们进行了一项随机、双向交叉研究和一项前瞻性、比较、非盲法研究。在使用加湿器和喷雾1周前后测量气管湿度和温度。结果:吸入和雾化后,气管温度和总含水量均显著升高(研究1)。雾化后环境空气和气管空气之间的温度梯度显著升高,而吸入后没有升高(研究2)。喷水和吸入后水梯度升高不显著。吸入和喷雾后的水梯度无显著差异。结论:由于两种输水方式的温度和湿度增加,分子水并不优于颗粒水。由于其易于使用,便携性和保湿效果,气管喷雾剂可能为气管造口术后护理提供额外的选择。

Lower airway humidification in spontaneously breathing tracheostomized patients: comparative study of trachea spray versus heated humidifier.

Background: Our aim was to compare inhalation with molecular water (vaporizing humidifier) and particulate water (trachea spray) in spontaneously breathing tracheostomized patients.

Methods: We performed a randomized, 2-way crossover study and a prospective, comparative, nonblinded study. Tracheal humidity and temperature were measured before and after use of a humidifier and spray for 1 week.

Results: After both inhalation and spray, the tracheal temperature and total water content increased significantly (study 1). The temperature gradient between ambient and tracheal air was significantly higher after spray, but not after inhalation (study 2). The water gradient increased nonsignificantly after spray and inhalation. The water gradient after inhalation or spray did not differ significantly.

Conclusions: Molecular water is not superior to particulate water because of temperature and humidity increase after both forms of water delivery. Because of its easy use, portability, and moisturizing effect, a trachea spray may offer additional options in postoperative tracheostomy care.
