目的:探讨对机械通气患者采用持续滴注呼吸机湿化水对呼吸机相关性肺炎(VAP)的影响。方法:将72例机械通气患者随机分成2组,实验组使用输液器接湿化罐持续滴注湿化水,对照组采用湿化罐装湿化液进行湿化,并保持水位不低于湿化罐标注下限。将两组患者使用中的湿化液采样培养以比较两组患者VAP的发生率,痰痂发生率。结果:实验组VAP的发生率及痰痂形成率明显低于对照组,差异有统计学意义(P<0.05),VAP患者的湿化液的污染与VAP的发生有直接相关性。结论:机械性通气患者使用输液器持续滴注湿化水,可一定程度降低VAP的发生并减少痰痂形成。
Objective: To investigate the effect of continuous drip-ventilator humidification water on ventilator-associated pneumonia (VAP) in patients with mechanical ventilation. Methods: Seventy-two patients with mechanical ventilation were randomly divided into two groups. In the experimental group, the infusion group was wetted with humidified water continuously. The control group was wetted with humidified canned wetting liquid and the water level was not lower than wet Canister marked lower limit. The two groups of patients in the wet sample fluid culture to compare the incidence of VAP in both groups, the incidence of sputum scab. Results: The incidence of VAP and the rate of sputum scab formation in the experimental group were significantly lower than those in the control group (P <0.05). There was a direct correlation between the contamination of wetting fluid and VAP in VAP patients. CONCLUSIONS: Continuous infusion of humidified water by infusion in patients with mechanical ventilation can reduce the incidence of VAP to a certain extent and reduce the formation of phlegm.
