About this study
Official title: A Study to Evaluate the Efficacy of Seattle-PAP for the Respiratory Support of Premature Infants
The investigators propose to test the hypothesis that Seattle bubble nasal continuous positive airway pressure (Seattle-PAP) supports respiratory physiology in very low birth weight (VLBW) infants more effectively than standard bubble nasal continuous positive airway pressure.
Read the detailed description
The primary outcome variable is work of breathing (WOB) over a two hour period, estimated from pressure-rate products, which are assessed with 6 Fr (2 mm) catheters placed in the distal esophagus for monitoring esophageal pressures (Pes), thereby estimating changes in pleural pressures during breath cycles. The following endpoints would also be assessed: Oxygen saturations and Fraction of Inspired Oxygen (FiO2) needed to keep saturations in acceptable ranges, Heart Rates (HR), transcutaneous carbon dioxide (TcPCO2), and respiratory rates throughout the 6 hour study period.
Objective determination of when an infant requires more or less respiratory support is difficult, but measurements of pressure-rate products as estimates of work of breathing, using esophageal catheters, can estimate an infant's respiratory effort. However, objective, simple-to-use, low cost, and non-invasive methods and tools to determine an infant's respiratory effort do not exist currently.
This study also is designed to test the hypothesis that infants' chest and abdominal movements can be assessed quantitatively from video images in ways that can be correlated with intrathoracic pressures, as measured with esophageal catheters.

The primary outcome is the main question the study is designed to answer.
Work of Breathing
The primary outcome variable is work of breathing (WOB) over three two hour periods, estimated from pressure-rate products, which are assessed with 6 Fr (2 mm) catheters placed in the distal esophagus for monitoring esophageal pressures (Pes), thereby estimating changes in pleural pressures during breath cycles.
Measured: Six hours
Secondary outcomes (1)
Video Recordings of Chest and Abdomen Movements during Breathing
This study also is designed to test the hypothesis that infants' chest and abdominal movements can be assessed quantitatively from video images in ways that can be correlated with intrathoracic pressures, as measured with esophageal catheters.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Seattle-PAP in people with Respiratory Distress Syndrome In Premature Infants and Bronchopulmonary Dysplasia, run by Seattle Children's Hospital 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 5 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: finished, as of the sponsor's last update on 14 Apr 2016. 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.
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?
Work of Breathing (time frame: Six hours). 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 14 Apr 2016; AzTrials last refreshed its copy on 7 Nov 2026.
