Impact of Tracheal Cuff Shape on Microaspiration in Intensive Care Units

Not Applicable
Completed
Conditions
Ventilator Associated Pneumonia
Critical Illness
Mechanical Ventilation Complication
Interventions
Device: tapered PVC-cuffed tracheal tubes
Device: Standard PVC-cuffed tracheal tube
Registration Number
NCT01948635
Lead Sponsor
University Hospital, Lille
Brief Summary

The investigators hypothesized that PVC tapered-cuff tracheal tubes would reduce microaspiration of gastric content as determined by pepsin level in tracheal aspirate.

Detailed Description

Microaspiration is the main route for entry of contaminated secretions into the lower respiratory tract of intubated critically ill patients. Tracheobronchial colonization might progress to ventilator-associated pneumonia (VAP) when the quantity and virulence of bacteria are high and when local and general host defenses are weak.

Recent in vitro and animal studies suggest that tapered-cuff tracheal tubes could be associated with reduced microaspiration of contaminated secretions and might be helpful in preventing VAP.
