摘要

目的:探讨机械通气中呼吸机湿化罐液体的更换时间。方法:将33例机械通气患者随机分为观察组和对照组

观察组采用7d更换呼吸机湿化罐液体

对照组采用每天更换呼吸机湿化罐液体

分别每天对2组的湿化罐液体采样进行细菌培养。结果:观察组采集样本119例

有细菌生长3例（2.5%）;对照组采集样本112例

有细菌生长15例（13.4%）。结论:呼吸机湿化液频繁更换可能造成细菌污染

7d更换湿化液的细菌污染率明显低于每天更换湿化液的细菌污染率。

Abstract

Objective:To study on the best replacement time of breathing humidification pot liquid in mechanical ventilation.Methods:33 mechanical ventilation patients were randomly divided into observation group and control group

in the observation group the humidification pot liquid were replaced 7 days

while in a control group were replaced every day

all liquid samples were cultured for bacteria.Results:119 samples collected in observation group have 3 cases with positive bacterial growth(2.5%)

while 112 samples collected in control group have 15 cases with positive bacterial growth(13.4%).Conclusion:Replace humidification pot liquid of breathing machine everyday may cause bacterial pollution more easily than they were replaced in 7 days interval.
