两种气道湿化方法在气管切开患者中的应用比较

目的探讨微量泵控制持续气道湿化在气管切开患者的应用及对其并发症的影响。方法选取气管切开患者120例,随机分为两组,实验组60例应用微量泵控制持续气道湿化,对照组60例应用传统的间断或定时气道湿化法,并进行连续观察。结果实验组的并发症和吸痰次数少于对照组,吸痰时及吸痰后2～5min实验组经皮血氧饱和度均值高于对照组。结论微量泵控制持续气道湿化在气管切开患者的应用效果明显,可以明显减少并发症的发生,减少吸痰次数,减轻吸痰所致低氧血症程度并缩短其持续时间。

Application of Continuous Airway Humidification after Tracheotomy

Objective To explore the application of micro-pump controlled continuous airway humidification airier tracheotomy and its complications. Methods We divided 120 cases of tracheotomy randomly into two groups：experimental group and control group with 60 cases in each. The micro-pump controlled continuous airway humidification was used for the experimental group and the conventional humidification （discontinuously or at definite time） was used for the control group. The two groups were under continual observation. Results The experimental group showed the lower incidence of complications,less frequency of sputum aspiration and higher oxygen saturation at and 2 - 5min after aspiration compared with the control group. Conclusion Micro-pump controlled continuous airway humidification after tracheotomy can significantly reduce the incidence of complication after tracheotomy,decrease the frequency of sputum aspiration and improve oxygen saturation caused by aspiration.
