OLA to Lowest DP in Cardiac Surgery
A study testing DP-PEEP and RM-5 in people with Lung Collapse, run by Fundación para la Investigación del Hospital Clínico de Valencia at 1 site in Spain.
Trial summary
This study aims to compared the effects in driving pressure of an open-lung strategy with a positive end-expiratory pressure (PEEP) titrated to best driving pressure (DP) after a RM versus the recommended protective PEEP of 5 cmH2O without a recruitment manuever in non-obese patients undergoing cardiac surgery.

About this study
Official title: Open-lung Ventilatory Approach With Positive End-expiratory Pressure Titrated to Lowest Driving Pressure in Cardiac Surgery Patients
This study aims to compared the effects in driving pressure of an open-lung strategy with a positive end-expiratory pressure (PEEP) titrated to best driving pressure (DP) after a RM versus the recommended protective PEEP of 5 cmH2O without a recruitment manuever in non-obese patients undergoing cardiac surgery.
- Conditions
- Lung Collapse
- Being tested
- DP-PEEP, RM-5
- Medical subject headings
- Pulmonary Atelectasis
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
DP-PEEPProcedure or surgery
PEEP titration trial for the lowest DP after the alveolar recruitment maneuver
RM-5Procedure or surgery
Fixed standard PEEP after the alveolar recruitment maneuver
| Study group | Role | What they receive |
|---|---|---|
| DP-PEEP | Experimental | recruitment maneuver + individualized PEEP Receives: Procedure: DP-PEEP |
| RM-5 | Active comparator | recruitment maneuver + fixed standard PEEP Receives: Procedure: RM-5 |
What is being measured
The primary outcome is the main question the study is designed to answer.
driving pressure
The driving pressure is a physiological ventilatory parameter measured as platteau pressure minus PEEP. This parameter may be associated with postoperative pulmonary complications
Measured: intraoperative
Secondary outcomes (1)
Postoperative pulmonary complications
The most frequent postoperative pulmonary complications will be recorded (acute respiratory failure, pneumonia, atelectasis, need of ventilatory support, acute respiratory distress syndrome)
Measured: 72 first postoperative hours

Questions about this trial
What is this clinical trial studying?
A study testing DP-PEEP and RM-5 in people with Lung Collapse, run by Fundación para la Investigación del Hospital Clínico de Valencia at 1 site in Spain.
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 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 2 Oct 2018. 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 Spain. 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?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
driving pressure (time frame: intraoperative). 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 NCT03133754, which also lists 5 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?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Oct 2018; AzTrials last refreshed its copy on 31 Oct 2026.
