Trial summary

The renal Doppler resistive index (RRI) is a noninvasive tool that has been used to assess renal perfusion in the intensive care unit (ICU) setting. Many parameters have been described as influential on the values of renal RI. Read more about this study

About this study

The renal Doppler resistive index (RRI) is a noninvasive tool that has been used to assess renal perfusion in the intensive care unit (ICU) setting. Many parameters have been described as influential on the values of renal RI. Mechanical ventilation is associated with significant increases in the risk of acute kidney injury (AKI). Ventilator-induced kidney injury (VIKI) is believed to occur due to changes in hemodynamics that impair renal perfusion. The investigators hypothesized that patients who need mechanical ventilation should have a different response in RRI when different levels of Positive end expiratory pressure (PEEP) are applied. Investigators wish to describe changing in RRI due to changes in PEEP and to verify whether these changes could partially explain the occurrence of VIKI

What participants receive

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

  • PEEP changesProcedure or surgery

    All patients will be ventilated with a tidal volume of 6 ml/kg before the RRI assessment. Further, three level of PEEP (5, 10 and 15 cmH2O) will be randomly set. For each levels of PEEP, the RRI will be evaluated

What is being measured

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

  1. Occurence of AKI

    AKI will be defined according to Kidney Disease: Improving Global Outcomes (KDIGO) criteria

    Measured: once a day until day 7

Secondary outcomes (1)
  1. Change in RRI at different level of PEEP

    To compare median difference of RRI at PEEP 5 and PEEP 15 in patients who will develop (or not) AKI

    Measured: One a day until day 5

Questions about this trial

What is this clinical trial studying?

An observational study of Respiratory Distress Syndrome, Adult and Respiration, Artificial, run by Università degli Studi di Ferrara 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 1 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 28 Apr 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?

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?

Occurence of AKI (time frame: once a day until day 7). 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 NCT03969914, 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 28 Apr 2022.
