About this study

Official title: Rebound Pain Following Surgery With Regional Anesthesia Block: A Prospective Cohort Study

For some kinds of surgery, Anesthesiologists provide nerve blocks (regional anesthesia) to reduce pain from surgery by injecting freezing medication around deep nerves with ultrasound. Nerve blocks help with pain control following surgery and reduce the amount of strong opioids needed but relatively little research has focused on the pain that occurs once the nerve block has worn off. This is called rebound or transition pain.

This research study will prospectively collect data including pain scores before, during and after nerve blocks are given for surgery. We will look at the type of nerve blocks and other analgesia medications used with the aim of quantifying rebound pain to better understand how to limit it's impact on quality postoperative pain control.

What participants receive

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

  • Numerical Pain ScalesOther

    Patients who are about to receive regional nerve blocks will be administered a numerical pain scale (NRS) before, during and after the offset of the nerve block.

What is being measured

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

  1. Numerical Pain Scale

    Measured: 2-3 times per patient over the course of a nerve block, up to 48 hours after the stop of the block (single shot or cessation of nerve catheter)

Questions about this trial

What is this clinical trial studying?

An observational study of Regional Anesthesia Morbidity and Pain, Postoperative, run by University of Alberta 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 3 inclusion and 2 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 4 Mar 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 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 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?

Numerical Pain Scale (time frame: 2-3 times per patient over the course of a nerve block, up to 48 hours after the stop of the block (single shot or cessation of nerve catheter)). 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 NCT05357105, which also lists 5 linked publications.

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 4 Mar 2025.
