About this study

Official title: Intraoperative Methadone for the Prevention of Postoperative Pain: a Randomized, Double-blind Clinical Study in Orthopedic Surgery

The pain felt after orthopedic surgery in the absence of adequate locoregional anesthesia is often insufficiently controlled, especially during the first 24 hours postoperatively.

Methadone, due to its long half-life, may provide better pain control after orthopedic surgery when associated locoregional anesthesia cannot be performed.

Read more

It may be impossible to perform loco-regional anesthesia in various contexts: patient refusal, pre-existing neurological impairment, infection at the injection site, coagulopathies, inability to cooperate, total language barrier, allergy to anesthetics, unavailability of equipment (ultrasound, etc.) or equipped room, lack of experience of nursing staff in performing the block and in the postoperative management of the patient.

Intraoperative administration of methadone in these settings may be superior to sufentanil for pain control during the 24 hours post orthopedic surgery, and the pain control provided by methadone does not appear to imply a higher likelihood of adverse events related to opioids.

Being tested
Methadone Hydrochloride, Sufentanil Citrate

What participants receive

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

  • Methadone HydrochlorideDrug

    Classic induction of anesthesia (opioid, hypnotic and curare) but the team is blinded to the opioid used (sufentanil or methadone), which is prepared in identical syringes by the pharmacy

  • Sufentanil CitrateDrug

    Classic induction of anesthesia (opioid, hypnotic and curare) but the team is blinded to the opioid used (sufentanil or methadone), which is prepared in identical syringes by the pharmacy

What is being measured

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

  1. Total morphine consumption

    Total morphine consumption

    Measured: 72 hours

  2. Standard visual analogue scale (VAS)

    Pain is assessed using a standard visual analogue scale (VAS) in 11 points (from 0 (no pain) to 10 (worst pain))

    Measured: 24 hours

Secondary outcomes (1)
  1. Patient satisfaction

    Patient satisfaction is assessed by means of a questionnaire at the end of hospital stay

    Measured: 72 hours

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Methadone Hydrochloride and Sufentanil Citrate in people with Orthopedic Surgery, run by Brugmann University Hospital at 1 site in Belgium.

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 9 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: looking for participants now, as of the sponsor's last update on 7 Feb 2025. 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 Belgium. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Riccardo Mora, MD (00393292199132, riccardo.mora@chu-brugmann.be), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Total morphine consumption (time frame: 72 hours). The study lists 2 primary outcomes in all. 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 7 Feb 2025.
