What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Compare the change in pulmonary aeration during the test of weaning from mechanical ventilation (before, at the end, and 4-6 h after) between patients requiring re-ventilation before the 48th hour, and those weaned permanently.

    Compare the change in pulmonary aeration during the test of weaning from mechanical ventilation (before, at the end, and 4-6 h after) between patients requiring re-ventilation before the 48th hour, and those weaned permanently.

    Measured: before, at the end, and 4-6 h after

Secondary outcomes (6)
  1. Studying variations, during weaning from mechanical ventilation, of pressure of left ventricle filling (E / Ea) coupled with those of plasma BNP.

    Studying variations, during weaning from mechanical ventilation, of pressure of left ventricle filling (E / Ea) coupled with those of plasma BNP.

    Measured: in the 4-6 early hours

  2. Assessing the effects of E / Ea and BNP variations on the success or failure in the 4-6 early hours.

    Assessing the effects of E / Ea and BNP variations on the success or failure in the 4-6 early hours.

    Measured: in the 4-6 early hours.

  3. Compare the variations of lung ultrasound score during the test of the weaning from mechanical ventilation between patients failed the spontaneous breathing test (SBT) and those extubated after successful SBT.

    Compare the variations of lung ultrasound score during the test of the weaning from mechanical ventilation between patients failed the spontaneous breathing test (SBT) and those extubated after successful SBT.

    Measured: in the 4-6 early hours

  4. Comparison of levels epithelial and endothelial markers

    Measured: at h0, h1, h4, h6

  5. Constitution serum bank for epithelial (sRAGE) markers dosages

    Measured: at h0, h1, h4, h6

  6. constitution serum bank for endothelial (angiopoietin) markers dosages

    Measured: at h0, h1, h4, h6

Questions about this trial

What is this clinical trial studying?

An observational study of Adult Patients Ventilated More Than 48 h and Stable Respiratory and Hemodynamic Conditions for SBT, run by University Hospital, Clermont-Ferrand at 1 site 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 4 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: finished, as of the sponsor's last update on 7 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Compare the change in pulmonary aeration during the test of weaning from mechanical ventilation (before, at the end, and 4-6 h after) between patients requiring re-ventilation before the 48th hour, and those weaned permanently. (time frame: before, at the end, and 4-6 h after). 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 NCT01098773, which also lists 1 linked publication.

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 7 Aug 2026.
