Effects of Continuous Aspiration of Subglottic Secretion Combined with Intermittent Flushing in Patients with Artificial Airway Receiving Mechanical Ventilation

目的观察持续声门下吸引加间断冲洗在机械通气患者中的应用效果。方法选取2012年1～12月收住蚌埠医学院第一附属医院ICU机械通气患者30例作为观察组，另取2011年1—12月收住蚌医一附院ICU机械通气患者30例作为对照组。对照组采用常规吸痰方法吸引气道内滞留物，观察组在常规吸痰方法的基础上进行持续声门下分泌物吸引加间断冲洗，观察两组患者7d内呼吸机相关性肺炎（ventilator—associatedp neumonia，VAP）的发生情况，比较两组患者7d后VAP的发生率。结果观察组VAP发生率少于对照组（P〈0．05）。结论持续声门下吸引加间断冲洗可有效降低机械通气患者VAP的发生率。

Objective To investigate the application and effects of continuous aspiration of subglottie secretion combined with intermittent flushing in patients with artificial airway receiving mechanical ventilation. Methods Total 30 patients with mechani-cal ventilation from January 2012 to December 2012 in the ICU of our hospital were enrolled in the study. Other 30 patients with mechanical ventilation from January 2011 to December 2011 were taken as the control group. In control group, we used conven- tional methods to attract airway suctioning retentate, and in observation group, we used continuous subglottic secretions suction and intermittent flushing based on the conventional suction method. We observed the cases of VAP within seven days, and compared the incidence of VAP in both groups after 7 days（ ventilator-associated pneumonia,VAP）. Results The incidence of VAP stays in the observation group were lower than that in the control group （ P 〈 0.05 ）. Conclusion Continuous aspiration of subglottic secretion and intermittent flushing can effectively reduce the incidence of VAP.
