About this study

Official title: Determination of the Best Positive End-expiratory Pressure (PEEP) Based on Oxygenation or Driving Pressure in Patients With Acute Respiratory Distress Syndrome After Cardiac Thoracic Surgery

Determination of the best positive end-expiratory pressure (PEEP) based on oxygenation or driving pressure in patients with acute respiratory distress syndrome (ARDS) after cardiothoracic surgery

The use of a positive end-expiratory pressure in acute respiratory distress syndrome is obvious in ARDS management. On the one hand it serves to fight against the reduction of functional residual capacity (FRC) and enable the limitation of hypoxia; and on the other hand it allows the limitation of "opening/closing" lesions in pulmonary alveoli which lead to increase "bio trauma".

However elevated PEEP has harmful effect such as hemodynamic effect on the right ventricle and distension on healthy part of the lung.Other adverse effects are: decreasing cardiac output, increased risk of barotrauma, and the interference with assessment of hemodynamic pressures.

Ideally the adjustment of PEEP level must be done by taking into account each patient characteristic. PEEP titration based on blood gas analysis is one of the most used techniques by physicians.

Current guidelines for lung-protective ventilation in patients with acute respiratory distress syndrome (ARDS) suggest the use of low tidal volumes (Vt), set according to ideal body weight (IBW) of the patient, and higher levels of positive end-expiratory pressure (PEEP) to limit ventilator-induced lung injury (VILI). However, recent studies have shown that ARDS patients who are ventilated according to these guidelines may still be exposed to forces that can induce or aggravate lung injury.

Driving pressure (DP) is the difference between the airway pressure at the end of inspiration (plateau pressure, Ppl) and PEEP.

Driving pressure may be a valuable tool to set PEEP. Independent of the strategy used to titrate PEEP, changes in PEEP levels should consider the impact on driving pressure, besides other variables such as gas exchange and hemodynamics. A decrease in driving pressure after increasing PEEP will necessarily reflect recruitment and a decrease in cyclic strain. On the contrary, an increase in driving pressure will suggest a non-recruitable lung, in which overdistension prevails over recruitment.

The main purposes of this study are to assess the optimal PEEP based on the best driving pressure or the best oxygenation.

Questions about this trial

What is this clinical trial studying?

An observational study of Positive Expiratory Pressure and Acute Respiratory Distress Syndrome, run by Centre Chirurgical Marie Lannelongue at 1 site in France.

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 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 23 Jan 2020. 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 France. 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?

Best PEEP level based on the best driving pressure value (time frame: 1 DAY). The study lists 2 primary outcomes in all. 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 23 Jan 2020.
