Trial summary

The investigators aimed to establish a prospective cohort of patients undergoing cardiopulmonary bypass (CPB) in cardiac surgery from April 2021 to September 2022, in Wuhan. The ARDS events, ventilation time, time of extubation, oxygenation index for 3 days after operation were observed. Read more about this study

About this study

Official title: Explore Potential Plasma Biomarkers of Acute Respiratory Distress Syndrome (ARDS) Using Proteomics Analysis in Patients Undergoing Cardiopulmonary Bypass

The investigators aimed to establish a prospective cohort of patients undergoing cardiopulmonary bypass (CPB) in cardiac surgery from April 2021 to September 2022, in Wuhan. The ARDS events, ventilation time, time of extubation, oxygenation index for 3 days after operation were observed. Plasma samples were collected before CPB, and several time points after CPB. Dynamic differential proteins of ARDS after CPB were screened by DIA (Data independent acquisition) proteomics. Quantitative protein marker concentration was used to predict the occurrence of ARDS after operation, the model discrimination and calibration was assessed.

What is being measured

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

  1. Number of participants with postoperative ARDS events as assessed by Berlin Definition.

    The Berlin Definition of Acute Respiratory Distress Syndrome:

    1. Timing: Within 1 week of a known clinical insult or new or worsening respiratory symptoms;
    2. Chest imaging: Bilateral opacities-not fully explained by effusions, lobar/lung collapse, or nodules;
    3. Origin of edema: Respiratory failure not fully explained by cardiac failure or fluid overload. Need objective assessment (eg, echocardiography) to exclude hydrostatic edema if no risk factor present;
    4. Oxygenation:

    Mild 200 mm Hg <PaO2/FIO2≤ 300 mm Hg with PEEP or CPAP ≥5 cm H2O; Moderate 100 mm Hg <PaO2/FIO2≤ 200 mm Hg with PEEP ≥5 cm H2O Severe PaO2/FIO2≤ 100 mm Hg with PEEP ≥5 cm H2O

    Measured: 3 days after operation

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Respiratory Distress Syndrome, run by Huazhong University of Science and Technology at 2 sites in China.

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 13 Dec 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 China. 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?

Number of participants with postoperative ARDS events as assessed by Berlin Definition. (time frame: 3 days after operation). 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 NCT04696172, 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 13 Dec 2022.
