Study Description

Brief Summary:
Underinflation and overinflation of tracheal cuff are common in intubated patients, including those intubated with polyurethane-cuffed tubes. The aim of this study is to determine the efficiency of a pneumatic device in controlling cuff pressure.

Condition or disease Intervention/treatment Phase
Mechanical Ventilation Complication Tracheal Intubation Morbidity Device: Pneumatic device, cylindrical or tapered cuff Phase 4

Detailed Description:
Underinflation and overinflation of tracheal cuff are associated with severe complications such as microaspiration of contaminated secretions, and tracheal ischemia. Efficient control of cuff pressure would probably allow reducing complications related to variations in cuff pressure.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Percentage of patients with underinflation or overinflation of cuff pressure [ Time Frame: 48 h ]
    Continuous recording of cuff pressure will be performed during 2 24-h periods (with or without the pneumatic device)


Secondary Outcome Measures :
  1. Impact of tracheal-cuff shape on variations in cuff pressure [ Time Frame: 48 h ]
    Patients will be intubated with cylindrical or tapered polyurethane cuffed tubes.

  2. Impact of continuous control of cuff pressure on microaspiration of gastric contents [ Time Frame: 48 h ]
    Pepsin will be quantitatively measured in tracheal aspirates of all patients during the 2 24-h periods (with or without the pneumatic device)

  3. Impact of tracheal cuff shape on microaspiration of gastric contents [ Time Frame: 48 h ]
    Pepsin level in tracheal aspirates will be compared between patients intubated with cylindrical polyurethane cuffed-tubes versus those intubated with tapered polyurethane cuffed-tubes
