About this study
Official title: Pericapsular Nerve Group Block With 20 ml 0.2% Ropivacaine vs 10ml 0.2% Ropivacaine and Dexamethasone in Total Hip Arthroplasty: A Randomized Controlled Trial
Does adding Dexamethasone to the Periarticular Nerve Group Block in Patients undergoing Total Hip Arthroplasty reduce the dose of ropivacaine?
Read the detailed description
Hip arthroplasty is one of the most common orthopaedic procedures, especially in elderly patients, due to the deformation of joints. Patients may complain of severe pain due to surgical trauma and prostheses. Regional anaesthesia methods may be performed to reduce the inflammatory response, opioid consumption, and opioid-related side effects.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Ropivacaine and Ropivacaine+Dexamethasone in people with Hip Osteoarthritis and Hip Pain Chronic, run by Poznan University of Medical Sciences at 1 site in Poland.
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 1 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 11 Jul 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 Poland. 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?
Time to first rescue opioid analgesia (time frame: 48 hours after surgery). 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 11 Jul 2025.
