About this study

Official title: The Effect of Perioperative Dexamethasone Administration on Postoperative Pain in Patients Undergoing Periacetabular Osteotomy: A Randomised Double-blind, Placebo-controlled Trial

This is an investigator-initiated, Danish mono-center, randomized, placebo-controlled, parallel group, double-blind, superiority trial of dexamethasone on postoperative pain management on patients undergoing operation for hip dysplasia with the periacetabular osteotomy procedure (PAO). 90 adults undergoing PAO will be enrolled.

The primary outcome is to compare the effect of dexamethasone relative to placebo on cumulated postoperative morphine consumption at 48 hours.

Key secondary outcomes include comparing the effect of repeated doses of dexamethasone relative to a single dose on cumulated postoperative morphine consumption at 48 hours, and to determine if dexamethasone is superior to placebo for: Perception of pain intensity, prevalence and degree of postoperative nausea and vomiting, and patient-reported outcome measures.

What is being measured

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

  1. Cumulated postoperative morphine consumption in milligrams after 48 hours.

    Morphine administered both as patient-controlled analgesia (PCA) i.v. morphine and any other supplemental morphine administered postoperatively. Consumption in mg.

    Measured: 0-48 hours postoperatively

Secondary outcomes (7)
  1. Postoperative pain intensity after 48 hours.

    Pain is evaluated at rest and under the timed-up-and-go (TUG) procedure. Pain intensity is assessed using the visual analogue scale (VAS) (0-100mm).

    Measured: 24, 48 hours postoperatively

  2. Cumulated postoperative morphine consumption from 48 hours until day 14 post operation

    Morphine consumption in milligrams after the operation.

    Measured: 48 hours - day 14 postoperatively

  3. Postoperative nausea and vomiting

    Nausea and vomiting are evaluated using a 4 point scale: none, mild, moderate, severe

    Measured: 24 and 48 hours postoperatively

  4. Antiemetic consumption

    Evaluation of cumulated antiemetic consumption in mg and drug will be assessed.

    Measured: 0-48 hours postoperatively

  5. Sleep

    Sleep quality will be assessed using the VAS scale (0-100)

    Measured: 0-7 days postoperatively

  6. Timed up and go test

    Is assessed from; the time that the participant takes to rise from a chair, walk three meters, turn around, walk back to the chair, and sit down.

    Measured: 24, 48 hours postoperatively

  7. Serious adverse events (SAE)

    SAE's including wound infection treated with antibiotics or revision. Patients will be asked for SAE during the intervention period, at a follow-up visit 8 weeks the operation. This will be supplemented with a look up for prescriptions.

    Measured: 0-8 weeks after operation

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Dexamethasone 24mg Solution for Injection and Saline Solution for Injection in people with Dexamethasone and Hip Dysplasia, run by Odense University Hospital at 1 site in Denmark.

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 4 inclusion and 10 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 2 Apr 2024. 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 Denmark. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

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?

Cumulated postoperative morphine consumption in milligrams after 48 hours. (time frame: 0-48 hours postoperatively). 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 NCT03874936, 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 2 Apr 2024.
