Study on effect of dual servo heating humidifier for airway humidification of patients with open-mouth breathing

[目的]研究双伺服加温湿化器用于张口呼吸病人气道湿化的临床效果。[方法]将100例张口呼吸病人随机分为两组,试验组采用Fisher&Paykel双伺服加温湿化器(MR850)持续湿化,对照组采用压缩雾化吸入机持续雾化吸入,观察比较24h后口腔黏膜湿化效果、气道评分、痰液黏稠度、气道湿化效果、呼吸、血气分析变化,并观察24h、48h、72h气道不良反应发生情况。[结果]两组口腔黏膜湿化效果、痰液黏稠度、肺部啰音、刺激性咳嗽、PaO2比较差异均有统计学意义(P<0.05)。[结论]双伺服加温湿化器对张口呼吸病人气道起到了良好的气道湿化效果,痰液引流通畅,口腔黏膜痰痂形成明显减少,血气分析指标改善,降低了肺部并发症发生的风险,不良反应发生率低。

Objective：To study the clinical effect of dual servo heating humidifier for airway humidification of pa-tients with open mouth breathing.Methods：A total of 100 patients with mouth breathing were randomly divid-ed into two groups.Test group cases used Fisher ＆ Paykel dual servo heated humidifier （MR850）continuous humidification.Patients in control group used compression atomizing inhalation machine continuous inhalation. Oral mucosa humidification effect,airway score,sputum viscosity,the effect of airway humidification,breathing changes of blood gas analysis were observed and compared after 24 h.And the occurrence of airway adverse re-actions was observed at 24 h,48 h,72 h.Results：To compare differences of oral mucosa humidifying effect,spu-tum viscosity,pulmonary rales,irritating cough,PaO 2 of the test group with control,there were statistically sig-nificant differences（P 〈0.05 ）.Conclusion：Dual servo heating humidifier played a good airway humidification effect for patients with open mouth breathing.Sputum drainage unobstructed.Formation of oral mucous sputum callus was significantly reduced.And blood gas analysis index improved.The risk of pulmonary complications reduced.It can lower the incidence of adverse reactions.
