Trial summary

Neurally adjusted ventilatory assist (NAVA) is a new concept of mechanical ventilation. NAVA delivers assist to spontaneous breathing based on the detection of the electrical activity of the diaphragm. We study the effect of changing ventilatory parameters on the patient's breathing pattern during NAVA. Read more about this study

About this study

Official title: The Effect of Positive End Expiratory Pressure (PEEP) on the Breathing Pattern During Neurally Adjusted Ventilatory Assist (NAVA)

Neurally adjusted ventilatory assist (NAVA) is a new concept of mechanical ventilation. NAVA delivers assist to spontaneous breathing based on the detection of the electrical activity of the diaphragm. We study the effect of changing ventilatory parameters on the patient's breathing pattern during NAVA.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing neurally adjusted ventilatory assist (NAVA) in people with Mechanical Ventilation, run by Insel Gruppe AG, University Hospital Bern at 1 site in Switzerland.

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 3 inclusion and 17 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 9 Sep 2009. 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 Switzerland. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Change in diaphragmatic Edi (area under the curve) during expiration (time frame: At each intervention). 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 NCT00529347, which also lists 2 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 9 Sep 2009.
