About this study

This study aims to compare 2 alveolar recruitment maneuvers (ARM) in patients with cerebral injuries and acute respiratory distress syndrome (ARDS) in term of efficacy and tolerance.

Read the detailed description

Two ARM are compared in this study:

  • The eSigh or extended sigh with increase of PEEP for 10 minutes to maintain plateau pressure at 40 cmH2O. During ARM, the peak pressure is limited to 50 cm H2O with decrease of tidal volume (Vt) if necessary.
  • The continuous positive airway pressure, or Continuous Positive Airway Pressure (CPAP) with application of a positive pressure of 40 cm H2O for 40 seconds without tidal volume.

Patients are randomized to receive in cross-over 2 ARM: CPAP and Extended Sigh (eSigh). The following data: oxygen tissue partial pressure (PtiO2), respiratory parameters, systemic and intracerebral hemodynamic parameters are collected before, after 1 minute, 10 minutes and 60 minutes for each ARM.

  2. Comparison of Intracranial hemodynamic parameters

    Comparison between the two ARM of Intracranial hemodynamic parameters: ICP (Intracranial pressure) , cerebral perfusion pressure and Transcranial Doppler (pulsatility index, mean, systolic and diastolic velocities)

    Measured: 60 minutes

  3. Comparison of blood oxygen level

    Comparison between the two ARM of haematosis: Blood oxygen level (SpO2)

    Measured: 60 minutes

  4. Comparison of partial pressure of carbon dioxide

    Comparison between the two ARM of partial pressure of carbon dioxide (PaCO2),

    Measured: 60 minutes

  5. Comparison of arterial blood gases

    Comparison between the two ARM of arterial blood gases (partial pressure of oxygen (PaO2),

    Measured: 60 minutes

  6. Comparison of end-tidal CO2

    Comparison between the two ARM of end-tidal CO2

    Measured: 60 minutes

  7. Comparison of Respiratory parameters

    Comparison between the two ARM of Respiratory parameters: plateau pressure and static lung compliance.

    Measured: 60 minutes

  8. Comparison of PtiO2

    Comparison between the two ARM of PtiO2

    Measured: 60 minutes

Questions about this trial

What is this clinical trial studying?

A study testing alveolar recruitment maneuvers group 1 and alveolar recruitment maneuvers group 2 in people with Cerebral Injuries and Acute Respiratory Distress Syndrome (ARDS), run by University Hospital, Toulouse at 5 sites in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 1 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Difficulty with inclusion, demotivation of centers in general). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Comparison of oxygen tissue partial pressure (PtiO2) values (time frame: 60 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02574169, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jun 2026.
