摘要
目的:探讨在危重病患者机械通气中应用呼吸过滤器的可行性和效果。方法:对54例行呼吸过滤器持续气道湿化过滤的观察组和50例行呼吸机本身具有的加温湿化和雾化装置的对照组进行对比分析,比较两组呼吸道和吸痰次数、呼吸道阻塞及呼吸机相关性肺炎发生率(VAP)。结果:两组在湿化、雾化和吸痰等日常护理次数上对比差异无统计学意义(P>0.05),而在气道阻塞发生率和VAP发生率上对比则差异明显(P<0.05)。在痰培养阳性(例)率上观察组低于对照组(P<0.01)。结论:呼吸过滤器可对人工气道及呼吸机内外管路中细菌进行截留,从而降低呼吸机相关性肺炎发生率。
Objective：To explore the gravely ill patients with mechanical ventilation in the feasibility and effect of the breath filter applied.Methods：The 54 regular breathing filter continuous airway moist filter group and 50 regular breathing machine itself has the increase in the number of temperature humidity and atomization device control group for comparison and analysis,comparing two groups the respiratory tract and the number of sputum suction,airway obstruction and the incidence of ventilator associated pneumonia （VAP）.Results：Two groups in wet,atomization and sputum suction contrast difference on number of daily care such as no statistical significance（P〉0.05）,and comparison on the incidence of airway obstruction and the incidence of VAP is significant difference （P〈0.05）.On the rate of sputum culture positive （cases） group is lower than the control group （P〈0.01）.Conclusion：The breath filter of artificial airway and breathing machine inside and outside the bacteria to intercept in pipeline,thereby reduce the incidence of ventilator associated pneumonia.
