Influence of washable type subglottic attract on incidence of ventilator- associated pneumonia in patients with mechanical ventilation

Abstract

Objective To explore the influence of washable type subglottic attract on incidence of ventilator-associated pneumonia (VAP) in patients with mechanical ventilation. Methods 356 cases in need of mechanical ventilation from July 2009 to July 2010 in our hospital were chosen as the research object.They were randomly divided into the observation group and the control group with 178 cases in each group.The control group was treated with conventional endotracheal tube for mechanical ventilation.The observation group used washable type subglottic endotracheal tube to attract for mechanical ventilation.The VAP rate for the two groups occurred during mechanical ventilation in ventilator was compared.Migration of the dominant bacteria of the subglottic secretion was detected,underwent pathogenic examination and drug sensitivity test. Results The VAP rate was significantly lower in the observation group than that of the control group.186 bacteria strains were detected from subglottic secretion,and 169 were detected from lower respiratory tract. Conclusions Washable type subglottic attract for mechanical ventilation can reduce the risk of ventilator-associated pneumonia for patients with mechanical ventilation significantly,and it is worthy of clinical application.
