About this study
Effect of perineurial dexamethasone and dexmedetomidine on popliteal nerve block duration for pediatric, ankle or foot surgery
Read the detailed description
This study is proposed to explore the effect of perineurial Dexamethasone and Dexmedetomidine on erector spinal plane block duration for pediatric, idiopathic scoliosis surgery.
After scoliosis surgery, children need good analgesia. Peripheral nerve blocks have provided a safe, effective method to control early postoperative pain when symptoms are most severe.
The safety of local anesthesia is essential in children due to the much lower toxicity threshold of local anesthetics. An effective adjuvant, such as Dexamethasone or Dexmedetomidine, could allow for a higher dilution of local anesthetics while maintaining and enhancing their analgesic effect.
There is considerable research where intravenous and perineural dexamethasone and Dexmedetomidine use has been compared in adults. However, there is a massive lack of research regarding children.
In this study, investigators compare perineural Dexamethasone and Dexmedetomidine. Group 2 has dexamethasone doses of 0.1mg/kg, and group 3 has 0,1ug/kg Dexmedetomidine added to the local anesthetic.
The investigator aims to find a dexamethasone or dexmedetomidine that covers the need for good pain relief and fast recovery postoperatively.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing 0.9%sodium chloride, Dexamethasone and Dexmedetomidine in people with Foot Injuries and Disorders and Ankle Injuries and Disorders, run by Poznan University of Medical Sciences at 2 sites 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 2 inclusion and 8 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 2 sites 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. 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 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?
first need of opiate (time frame: 48 hours). 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 NCT06233565, 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 11 Jul 2025.
