人工气道气囊上方滞留物间断持续引流对呼吸机相关肺炎的影响

目的观察人工气道气囊上方滞留物间断持续引流对呼吸机相关肺炎(ventilator associated pneumonia,VAP)的影响。方法将132例行人工气道患者分为对照组70例和试验组62例,对照组在患者呛咳,听诊肺部有痰鸣音或者血氧饱和度下降时吸痰;试验组采用滞留物间断持续引流的方法,观察两组VAP发生率。结果试验组患者VAP发生率为17.7%,对照组为32.9%,两组比较,χ2=3.928,P0.05,差异具有统计学意义。结论气囊上方滞留物采用间断持续引流可有效降低VAP的发生率。

Effect of continuous drainage of subglottic secretion on ventilator associated pneumonia

Objective To study the effect of continuous drainage of subglottic secretion on ventilator associated pneumonia （VAP）. Method One hundred and thirty two patients undergoing continuous drainage of subglottic secretion were divided into the control group （n = 70） and the experiment group （n = 62）： the former group underwent sputum suction in case of bucking, wheezy phlegm or decreased oxygen saturation and the latter continuous drainage of subglottic secretion. The incidence of VAP was compared between the two groups. Result The incidences of VAP in the experiment and control groups were 17.7% and 32.9%, respectively, with significant difference between the groups （ X2 = 3.928, P 〈 0.05）. Conclusion The continuous drainage of subglottic secretion can effectively reduce the incidence of VAP.
