Trial summary

The diaphragm is the fundamental muscle of the respiratory system. The diaphragmatic dysfunction is present in 60% of critical patients at hospital admission and up to 80% after prolonged mechanical ventilation and difficult weaning. Read more about this study

About this study

Official title: Effects of Mechanical Ventilation on the Diaphragm in COVID-19 Intensive Care Patients. A Post-mortem Pathology Study.

The diaphragm is the fundamental muscle of the respiratory system. The diaphragmatic dysfunction is present in 60% of critical patients at hospital admission and up to 80% after prolonged mechanical ventilation and difficult weaning.

Risk factors associated with diaphragm dysfunction and atrophy are sepsis, trauma, sedatives, steroids, and muscle relaxants.

Read more

The main pathology characteristics of diaphragm biopsies of mechanically ventilated patients are atrophy and a reduction in contractility, determining an impact on the clinical outcome.

Shi et al. found a higher section area of the diaphragm muscle fiber in biopsies of post mortem COVID-19 patients versus negative patients, independently from days of mechanical ventilation.

The hypothesis of our study is to identify different clusters of pathological presentation in post-mortem COVID-19 mechanically ventilated patients.

What is being measured

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

  1. Clinical characteristics

    Evaluate if there are specific clusters in the study population and find different clinical characteristics.

    Measured: One week post mortem

  2. Blood test characteristics

    Evaluate if there are specific clusters in the study population and find different blood test characteristics.

    Measured: One week post mortem

  3. Pathology characteristics

    Evaluate if there are specific clusters in the study population and find different pathology characteristics.

    Measured: One week post mortem

Secondary outcomes (3)
  1. Mechanical ventilation

    Verify if there are correlations between the clusters characteristics and the other variables in the study population mechanical ventilation.

    Measured: One week post mortem

  2. Therapy

    Verify if there are correlations between the clusters characteristics and therapy in the study population.

    Measured: One week post mortem

  3. Arterial blood gas analysis

    Verify if there are correlations between the clusters characteristics and arterial blood gas in the study population.

    Measured: One week post mortem

Questions about this trial

What is this clinical trial studying?

An observational study of Diaphragm Injury and Pathology, run by Azienda Sanitaria-Universitaria Integrata di Udine at 2 sites in Italy.

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 1 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 13 Jan 2022. 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 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?

Contact Luigi Vetrugno, MD (+ 39 0432559509, luigi.vetrugno@asufc.sanita.fvg.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical characteristics (time frame: One week post mortem). The study lists 3 primary outcomes in all. 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 NCT05191433, which also lists 6 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?
