Overview
Brief Summary
During invasive mechanical ventilation, maintaining endotracheal tube cuff pressure (Pcuff) around 25 cmH2O is recommended for sealing the upper airways. The continuous control of Pcuff with a simple mechanical device, the Tracoe Smart CuffmanagerTM, has never been assessed. The investigators hypothesize that the Tracoe Smart CuffmanagerTM would allow a reduction of the incidence of underinflation episodes, as compared with the intermittent strategy of Pcuff control.
Detailed Description
During invasive mechanical ventilation, maintaining a tracheal cuff pressure (Pcuff) around 25 cmH2O is recommended to prevent cuff over- (\> 30 cmH2O) and underinflation (\< 20 cmH2O), identified as risk factors for tracheal ischemic damage and for oropharyngeal microaspirations, respectively. Intermittent measurements with intermittent adjustments of Pcuff is the widely used strategy but, between measurements, over- and underinflation episodes could occur. Devices allowing a continuous control of Pcuff are therefore appealing. As microaspiration is the most relevant mechanism for ventilator-associated pneumonia (VAP), the use of such devices may decrease the incidence of VAP for instance. To the knowledge of the investigators, the continuous control of Pcuff with a simple mechanical device, the Tracoe Smart CuffmanagerTM, has never been assessed. The investigators hypothesize that the Tracoe Smart CuffmanagerTM would allow a reduction of the incidence of underinflation episodes, as compared with the intermittent strategy of Pcuff control. As secondary objectives, the investigators aim to assess the impact of the use of the Tracoe Smart CuffmanagerTM on the incidence of overinflation episodes and on the incidence of early ventilator-associated pneumonia. A homogenous population will be studied for this purpose: patients admitted with severe acute brain damage.

Eligibility Criteria
Inclusion Criteria
- •with severe acute brain damage
- •admitted in the ICU for less than 48 hours
- •and expected to receive invasive mechanical ventilation (through orotracheal tube with a low pressure-high volume cuff) for at least 48 hours after inclusion.

Outcomes
Primary Outcomes
Incidence of underinflation episodes
Time Frame: Day2
The primary outcome is to test whether the Tracoe Smart CuffmanagerTM reduces the incidence of underinflation episodes, as compared with the intermittent strategy of Pcuff control. Therefore, a comparison, between the 2 groups, of the incidence of Pcuff \<20 cmH2O measurements will be performed. Time Frame: Within the 2 days following the inclusion, all the intermittent Pcuff measurements will be collected as well as the incidence of Pcuff manual adjustments
Secondary Outcomes
- ICU length of stay(Within the 2 days following the inclusion)
- Duration of mechanical ventilation(Within the 2 days following the inclusion)
- ICU mortality(Within the 2 days following the inclusion)
- occurrence of early ventilator-associated pneumonia(During the first two weeks of hospital stay)
- incidence of Pcuff >30 cmH2O measurements (overinflation episodes)(Within the 2 days following the inclusion)
