BACKGROUND
After tracheostomy, the airway lacks an essential mechanism for warming and humidifying the inspired air with the consequent functional impairment and discomfort. The purpose of this study was to compare airway hydration with cold-air nebulization versus heated high-flow humidification on medical interventions and tracheal ciliary beat frequency (CBF).
METHODS
Newly tracheostomized patients (n = 20) were treated either with cold-air nebulization or heated humidification. The number of required tracheal suctioning procedures to clean the trachea and tracheal CBF were assessed.
RESULTS
The number of required suctions per day was significantly lower in the heated humidification group with medians 3 versus 5 times per day. Mean CBF was significantly higher in the heated humidification group (6.36 ± 1.49 Hz) compared to the cold-air nebulization group (3.99 ± 1.39 Hz).
CONCLUSION
The data suggest that heated humidification enhanced mucociliary transport leading to a reduced number of required suctioning procedures in the trachea, which may improve postoperative patient care.
背景
气管切开术后，气道缺乏对吸入空气进行加温和加湿的基本机制，从而导致功能受损和不适。本研究的目的是比较冷空气雾化与加热高流量湿化在医学干预和气管纤毛摆动频率（CBF）方面对气道水化的影响。
方法
对新行气管切开术的患者（n = 20）分别采用冷空气雾化或加热湿化治疗。评估清洁气管所需的气管吸痰次数和气管CBF。
结果
加热湿化组每天所需的吸痰次数显著更低，中位数为每天3次，而另一组为每天5次。与冷空气雾化组（3.99±1.39Hz）相比，加热湿化组的平均CBF显著更高（6.36±1.49Hz）。
结论
数据表明，加热湿化可增强黏液纤毛运输，减少气管所需的吸痰次数，这可能改善术后患者护理。
