About this study
Official title: Physiological Response to Prone Position in Intubated Adults With COVID-19 Associated Acute Respiratory Distress Syndrome (ARDS): a Retrospective Study
Retrospective study in COVID-19 ARDS patients hospitalised in the ICU. Investigators aim to explore the effects of prone positioning on oxygenation, dead space ventilation and mortality.
- Conditions
- ARDS, Sars-CoV-2 Infection
- Being tested
- Prone positioning
- Medical subject headings
- COVID-19
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Prone positioningProcedure or surgery
Prone position during invasive mechanical ventilation
What is being measured
The primary outcome is the main question the study is designed to answer.
PaO2/FiO2
Arterial partial pressure of oxygen / Fraction of inspired oxygen
Measured: Within 2 hours before pronation and 2 hours before supination
Secondary outcomes (3)
Alveolo-arterial oxygen gradient change
Measured: Within 2 hours before pronation and 2 hours before supination
Ventilatory Ratio
Measured: Within 2 hours before pronation and 2 hours before supination
Mortality or Extracorporeal membrane oxygenation (ECMO) support
Measured: Once between ICU admission and extubation

Questions about this trial
What is this clinical trial studying?
An observational study of ARDS and Sars-CoV-2 Infection, run by University of Lausanne Hospitals at 1 site in Switzerland.
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 3 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 3 Jun 2022. 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 Switzerland. 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?
PaO2/FiO2 (time frame: Within 2 hours before pronation and 2 hours before supination). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 3 Jun 2022.
