声门下滞留物引流预防呼吸机相关性肺炎的效果观察

Effect of subglotic secretion drainage on prevention of ventilator-associated with pneumonia

目的观察声门下滞留物引流预防呼吸机相关性肺炎(VAP)的临床效果。方法选2008年10月-2010年10月收住我院急诊与重症医学科需要建立人工气道实施机械通气的18岁以上成年患者51例,随机分为普通组(n=51)和声门下组(n=37),比较两组VAP发生率。结果普通组VAP发生率47.1%,声门下组VAP发生率24.3%,两组差异有统计学意义(P<0.05)。结论有效的声门下滞留物引流可显著减低VAP的发生率。

Objective To investigate the clinical effect of subglottic secretion drainage on prevention of ventilator-Associated pneumonia（VAP）.Methods From October 2008 to October 2010,51 cases over 18 age were admitted to department of emergency and ICU for establishing arfificial airway to perform mechanical ventilation.These patients were randomly divided into the common group（n=51） and subglottic group（n=37）,The incidence of VAP was compared between two groups.Results The incidence rate of VAP is 47.1% in common group,and 24.3% in stagnation group.The difference of two group is statistical significance.Conclusions The efficient subglotic secretion drainage could reduce significantly incidence rate of VAP.
