老年患者全麻术后雾化吸入间歇期生理盐水湿化的疗效观察

目的研究生理盐水气道湿化对老年患者全麻术后排痰的影响。方法将58例全麻手术后的老年患者，随机分为常规组（n=29）及湿化组（n=29），常规组按常规进行药物雾化吸入，间歇期使用鼻导管或面罩吸氧，湿化组在常规药物雾化吸入的间歇期持续使用生理盐水湿化，观察患者咯出第1口痰时间、术后痰液性状改变的时间、痰量、心率、呼吸及血氧饱和度。结果与常规组比较，湿化组的排痰时间、痰液性状改变时间缩短（P〈0．05），术后前2d痰量明显增加（P〈0．05）。结论老年患者术后在雾化吸入的间歇期持续生理盐水气道湿化，能促进早期排痰，无显著副作用，安全有效，值得临床推广。

Observation on efficacy about saline airway humidification in intermission of aerosol inhalation after operation in elder patients

Objective To investigate the effect of saline airway humidification on sputum excretion after operation in elder patients. Methods Elder patients who received operations were randomly divided into routine treatment group with common medicine aerosol inhalation by mask oxygen inhalation, and humidification group with continuous saline airway humidification in intermission of common medicine aerosol inhalation. We mainly examined the time of first sputum, the time of sputum changing characters, sputum amount, heart rate,respiration and blood oxygen saturation. Results Compared with routine group, the humidification group obviously shorten sputum excretion duration, character changing time, and sputum amount significantly increase in 48 hours after operation( P ＜ 0.05 ). Conclusions The continuous saline humidification in intermission of common medicine aerosol inhalation after operations could accelerate the process of sputum excretion. It is efficacy and safety, and it deserves clinical application.
