About this study

Official title: Mechanical Ventilation Guided By Transpulmonary and Airway Driving Pressures in the Setting of Intra-abdominal Hypertension

Esophageal pressure measurements in surgical patients requiring mechanical ventilation during abdominal laparoscopic or robotic surgeries requiring intra-abdominal insufflation.

Read the detailed description

Decades of research and clinical observation in mechanical ventilation have demonstrated unequivocally that tidal volume (VT), plateau pressure (PPLAT) and PEEP (positive end-expiratory pressure) influence ventilator induced lung injury. Clinicians, however, have struggled in the attempt to find a single indicator of safety and risk. Recent analyses of the large multi-center randomized trials database suggest that Airway Driving Pressure (ADP) and Trans pulmonary Driving Pressure (DTP) are the variables of greatest importance and therefore the best single parameters on which to focus. In attempting to define their optimal values and their correlation between each other in the setting of intra-abdominal hypertension, we would like to compare standard of care mechanical ventilation (control) with mechanical ventilation guided by DTP and ADP (intervention) in patients undergoing abdominal laparoscopic surgery.

Questions about this trial

What is this clinical trial studying?

A study testing Esophageal pressure measurement guided ventilation in people with Surgery, run by Mayo Clinic at 1 site in United States.

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 18 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 2 Mar 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 United States. 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?

Airway driving pressure guided mechanical ventilation determined by esophageal balloon catheter measurements. (time frame: Through study completion, an average of one year). 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 2 Mar 2022.
