About this study

Postoperative pain is usually treated with opioids. Among them, oxycodone is popular in the daily practice as it is administered orally and is easily titrated. However, side-effects include increase duration and frequency of apneic episodes. Some authors believe that tramadol has less impact on these apneic episodes during the first postoperative night, based on a trial that reported conclusive results only during the first 2 postoperative hours. The objective of this randomized controlled trial is to compare the effect of postoperative pain treatment of oxycodone with tramadol on apneic episodes during the first and third postoperative nights.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Oxycodone and Tramadol in people with Sleep Apnea, run by Centre Hospitalier Universitaire Vaudois 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 2 inclusion and 5 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 27 Jan 2021. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Apnea hypopnea index while lying supine (time frame: Postoperative night 1). 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 NCT03454217, which also lists 1 linked publication.

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 27 Jan 2021.
