About this study

Official title: Use of the Boussignac CPAP System Immediately Following Extubation to Improve Lung Function in Adults With Moderate to Severe Obstructive Sleep Apnea

The purpose of this study is to assess the efficacy of the Boussignac positive airway pressure system (a mask) applied immediately following post-operative extubation in improving lung function in patients with obstructive sleep apnea (OSA). Assessments will be done before surgery and then at 1, 2 and 24 hours following extubation and will be compared to standard care for perioperative airway support. The study aims to give a broader and more inclusive picture (than the current literature) in terms of whether the Boussignac CPAP system should be considered for utilization by anesthesiologists caring for surgical patients with OSA.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Boussignac CPAP deviceDevice

    Also called Boussignac CPAP device,

    Is a continuous positive airway pressure (CPAP) system marketed in Canada and the US for the treatment of Obstructive Sleep Apnea. The main difference is that this system is portable wheres the standard hospital CPAP is not. This allows for the application immediately post-extubation.

  • standard CPAPDevice

    Also called standard of care CPAP

    Standard of care postoperative treatment for OSA.

Study groups in NCT01877928
Study groupRoleWhat they receive
Boussignac CPAP deviceExperimentalPatients previously diagnosed with obstructive sleep apnea and who are undergoing abdominal or peripheral surgery will have the Boussignac CPAP mask applied for 1 hour starting immediately post-extubation
Receives: Device: Boussignac CPAP device
standard CPAPActive comparatorPatients previously diagnosed with obstructive sleep apnea who are undergoing peripheral or abdominal surgical procedures will receive the standard-of-care for obstructive sleep apnea. This typically involves CPAP application only at night
Receives: Device: standard CPAP

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. percent forced vital capacity %(FVC)

    %FVC will be assessed 24 hours postoperatively in patients who received the Boussignac CPAP mask immediately post-extubation and these values compared to those of patients who received the standard-of-care treatment for obstructive sleep apnea

    Measured: 24 hours postoperatively

Secondary outcomes (1)
  1. % forced expiratory volume in 1 second (FEV1)

    Measured: 1,2 and 24 hours post-operatively

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted14 Jun 2013 (estimated)
  2. Study startJun 2013
  3. Primary completionJul 2016
  4. Study completionJul 2016

Why it stopped: Most OSA patients were not obese and/or admitted over night so the study was not feasible.

Questions about this trial

What is this clinical trial studying?

A study testing Boussignac CPAP device and standard CPAP in people with Obstructive Sleep Apnea (OSA), run by Queen's University at 1 site in Canada.

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 6 inclusion and 7 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: stopped early, as of the sponsor's last update on 20 Mar 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 Canada. 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 was stopped early (reason given: Most OSA patients were not obese and/or admitted over night so the study was not feasible.). Results are not available in the source record.

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?

percent forced vital capacity %(FVC) (time frame: 24 hours postoperatively). 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 20 Mar 2018.
