3种加湿法对人工气道湿化效果的对比分析

目的观察比较加热蒸汽加温加湿法和气道内直接滴注加湿法在心胸外科人工气道患者中的应用效果。方法回顾性分析169例气管插管行人工气道湿化患者,其中应用加热蒸汽加温加湿法48例、气道内直接滴注加湿法42例、同时使用加热蒸汽加温加湿法和气道内直接滴注加湿法89例;对三组病人气道湿化的临床疗效以及氧分压、血氧饱和度、心率和呼吸频率进行比较。结果加热蒸汽加温加湿法较气道内直接滴注加湿法,能够减少人工气道患者的刺激性咳嗽和肺部感染的发生,提高氧分压和氧饱和度,降低心率。同时应用加热蒸汽加温加湿法和气道内直接滴注加湿法,较单独应用加热蒸汽加温加湿法或气道内直接滴注加湿法能够显著减少人工气道患者的刺激性咳嗽、痰痂形成、气道粘膜出血以及肺部感染的发生,提高患者氧分压和氧饱和度,降低心率和呼吸频率。结论同时应用加热蒸汽加温加湿法和气道内直接滴注加湿法能更好的提高人工气道的湿化效果,减少人工气道并发症的发生。

Contrast analysis on effect of the humidification of artificial airway in the three kinds of wet methods

Objective To evaluate the effect of 3 kinds of wet method applied to the humidification of artificial airway in cardiothoracic surgery.Methods Respective analysis of 169 cases of artificial airway humidification,48 cases of heating vapor humidification,42 cases of dripping humidification,89 cases of combined.The clinical effect,saturation of blood oxygen,heart rate and respiratory frequency were observed in three groups.Results Irritable cough and pulmonary infection were less in heating vapor humidification group than in dripping humidification group,oxygen partial pressure and heart rate reduced either.But the combined was the best,irritable cough,phlegm crust formation,mucosal bleeding and pulmonary infection were reduced,meanwhile,oxygen partial pressure and saturation were improved.conclusion The combined humidification is benefit to the effect of humidification,it can reduce the complication of artificial airway.
