Airway Devices in Ventilator-Associated Pneumonia Pathogenesis and Prevention

Anahita Rouzé et al. Clin Chest Med.

Abstract

Airway devices play a major role in the pathogenesis of microaspiration of contaminated oropharyngeal and gastric secretions, tracheobronchial colonization, and ventilator-associated pneumonia (VAP) occurrence. Subglottic secretion drainage is an effective measure for VAP prevention, and no routine change of ventilator circuit. Continuous control of cuff pressure, silver-coated tracheal tubes, low-volume low-pressure tracheal tubes, and the mucus shaver are promising devices that should be further evaluated by large randomized controlled trials. Polyurethane-cuffed, conical-shaped cuff, and closed tracheal suctioning system are not effective and should not be used for VAP prevention.

Keywords: Device; Prevention; Subglottic secretion drainage; Tracheal tube; Ventilator-associated pneumonia.
