目的观察持续氧气雾化应用于气管切开患者时气道湿化的效果。方法对97例需要人工气道湿化的气管切开患者按气管切开日期的单双日随机分为两组,单日48例为实验组采用持续氧气雾化法,双日49例为对照组采用气道湿化液持续泵入法,对两组患者气道湿化的临床效果进行观察比较。结果应用持续氧气雾化的患者在刺激性咳嗽、气道黏膜损伤出血及肺部感染发生率方面显著低于气道湿化液持续泵入组,经χ2检验,差异有统计学意义(P<0.01)。结论持续氧气雾化行人工气道湿化能安全、有效地提高气管切开患者气道湿化的效果,可明显减少患者刺激性咳嗽、气道黏膜损伤出血及肺部感染的发生,并可减少吸痰次数、改善通气功能,提高氧合效率,减少了并发症的发生率。
Objective To observe the effect of continuous oxygen atomization on airway wetness in tracheotomy patients. Methods A total of 97 patients with tracheostomy requiring artificial airway humidification were randomly divided into two groups according to tracheotomy date. 48 patients on a single day were treated by continuous oxygen atomization method and 49 patients on a double day Group continued to use airway humidification fluid pump method, the clinical efficacy of two groups of patients with wet airway were observed and compared. Results Continuous oxygen atomization in patients with irritating cough, airway mucosal injury and pulmonary infection incidence was significantly lower than the continuous wet airway fluid pumped into the group by χ2 test, the difference was statistically significant (P < 0.01). CONCLUSIONS Continuous oxygen atomization can safely and effectively enhance airway wetness in patients with tracheotomy, which can significantly reduce the occurrence of irritating cough, airway mucosal injury and hemorrhage and lung infection in patients with tracheotomy. Reduce the number of sputum aspiration, improve ventilation, improve oxygenation efficiency and reduce the incidence of complications.
