In our knowledge there is only few data about the cough determinants in mechanically ventilated patients. However some failure of extubation is due to inefficiency cough. In order to determine some determinants of cough, the investigators propose to evaluate systematically different physiological parameters before and after extubation.

Condition Intervention
Mechanical Ventilation
Other: Functional respiratory evaluation

Study Type: Interventional
Study Design: Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label

Primary Outcome Measures:
  • Interest of systematically cough evaluation before extubation [ Time Frame: 2 days after extubation ] [ Designated as safety issue: Yes ]
    All the patients enrolled have a physiological evaluation before and after extubation. After extubation the evaluation will be done respectively at D0, D1, D3 and D5. The first endpoint is the success of extubation which is evaluated à D2.

Secondary Outcome Measures:
  • Correlation between success of extubation and respiratory parameters [ Time Frame: 2 days after extubation ] [ Designated as safety issue: No ]

Estimated Enrollment: 180
Study Start Date: March 2012
Estimated Study Completion Date: December 2015
Estimated Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Cough Determinants Other: Functional respiratory evaluation
Each enrolled patients has a pulmonary function test before and after extubation, and repeatedly at D1, D3, D5 (if they are always hospitalized)
Other Name: Pulmonary Function test

Detailed Description:

In order to evaluate, and identify the cough determinants, the investigators propose a physiological evaluation for each patients who were intubated and mechanically ventilated during at least 72 hours. Indeed inefficacy of cough after extubation is one of the main reason of extubation failure. However there is no any mean to evaluate it simply now.
