间歇性声门下吸引技术预防人工气道患者肺炎的效果观察

目的探讨间歇性声门下吸引(intermittent subglottic secretions drainage,ISSD)技术在人工气道管理中预防气管内导管相关性肺炎的效果。方法对本院重症监护室(intensive care unit,ICU)收治的100例建立人工气道的患者,采用随机数字法分为对照组和实验组,每组各50例。两组患者均按常规施行人工气道管理,实验组在此基础上施行ISSD技术。比较两组患者ICU住院期间气管内导管相关性肺炎发生率及发生时间。结果两组患者在ICU住院期间导管相关性肺炎发生率及发生时间比较,均P0.05,差异具有统计学意义,实验组患者导管相关性肺炎发生率明显低于对照组,肺炎发生时间明显长于对照组。结论在人工气道患者中应用ISSD技术,可明显减少患者导管相关性肺炎发生率及延缓发生时间,。

Effect of itermittent subglottic secretions drainage on management of artificial airway to prevent tuberelated pulmonary pneumonia

Objective To estimate the effect of itermittent subglottic secretions drainage（ISSD）on management of artificial airway to prevent tube-related pulmonary pneumonia.Methods One hundred ICU patients with intubation for artificial airway were divided equally into control and experiment group by random digits table.Both were managed with construction of artificial airway and besides the experiment group received ISSD. The two groups were compared in terms of incidence and occurrence time of catheter-related pneumonia, time for airway opening and ICU stay.Result The incidence and the occurrence time of pneumonia,time for airway opening and ICU stay time in the experiment group were significantly lower or shorter than those in the control group with statistical difference（ all P〈0.05）.Conclusion ISSD is effective in decreasing the incidence of catheter related pneumonia,shortening the occurrence time of catheter related pneumonia and ICU stay time for the patients with artificial airway.
