Trial summary

The purpose of the study is to determine to what extent the abdominal muscles contribute to airway pressure, in order to investigate the correlation between muscles weakness and extubation outcome in mechanically ventilated patients. In addition the reliability of the sonographic measurements will be assessed. Read more about this study

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Abdominal muscles ultrasoundDiagnostic test

    Abdominal muscles ultrasound during a spontaneous breathing trial using the M-mode to calculate the thickening fraction of the anterior and lateral abdominal muscles under multiple circumstances (tasks performed by the patients)

What is being measured

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

  1. Correlation between thickening fraction and SBT outcome

    Correlation between thickening fraction of each muscles evaluated by ultrasound before the SBT and the SBT outcome.

    Measured: Measurements will be performed before SBT

Secondary outcomes (2)
  1. Correlation between the pressures generated by respiratory muscles and SBT outcome

    Correlation between the pressures generated by respiratory muscles during the ultrasound measurements (Twice Transdiaphragmatic pressure, TwPdi; maximal inspiratory pressure, MIP) and SBT outcome

    Measured: Measurements will be performed before SBT

  2. Inter-rater agreement

    Concordance of measurements of abdominal muscle thickness and thickening fraction in mechanically ventilated patients performed by two different observers will be evaluated.

    Measured: Measurements will be performed before SBT

Questions about this trial

What is this clinical trial studying?

An observational study of Muscle Weakness and Weaning Failure, run by Azienda Socio Sanitaria Territoriale degli Spedali Civili di Brescia at 2 sites in 2 countries.

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 2 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 26 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Canada, Italy. 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?

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?

Correlation between thickening fraction and SBT outcome (time frame: Measurements will be performed before SBT). 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 NCT03567564, 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 26 Jun 2018.
