About this study
Scoliosis correction surgery in children is a complex procedure with significant risks, including postoperative pain, inflammatory response, and potential neurological complications. Effective pain control and minimizing inflammation are critical for faster recovery and improved patient outcomes. Dexamethasone is commonly used as an adjuvant in regional anesthesia due to its anti-inflammatory effects and ability to prolong analgesia. However, limited research exists on the optimal route of dexamethasone administration (intravenous vs. perineural) and the best local anesthetic concentration for pain management, inflammatory response, and neuromonitoring during surgery.
This study aims to compare the effects of different dexamethasone administration routes and local anesthetic concentrations on postoperative pain, inflammation (NLR, PLR), and neuromonitoring in pediatric scoliosis surgery. Results may improve regional anesthesia protocols, enhance patient safety, and offer valuable insights for clinical practice.
Read the detailed description
Scoliosis correction surgery in children is a complex procedure associated with a significant risk of postoperative pain, inflammatory response, and potential neurological complications. Ensuring optimal pain control and minimizing adverse inflammatory responses is crucial for shortening the recovery period, improving patient comfort, and reducing the risk of long-term complications. In clinical practice, dexamethasone is frequently used as an adjuvant in regional anesthesia techniques due to its anti-inflammatory properties and its potential to prolong the analgesic effect.
Although the use of dexamethasone as an adjuvant in regional anesthesia is well known, there is limited research focusing on the impact of its route of administration (local versus intravenous) and the optimal concentration of local anesthetic agents on the effectiveness of pain control, inflammatory response, and neuromonitoring parameters during surgical procedures in children. Understanding these aspects is particularly important in complex procedures such as scoliosis correction surgery, where precise neurological function monitoring is essential for patient safety.
The objective of the proposed study is to evaluate the impact of different dexamethasone administration routes (intravenous and perineural) and varying concentrations of local anesthetic agents on postoperative pain, inflammatory response (measured using NLR and PLR indices), and neuromonitoring parameters in children undergoing scoliosis correction surgery. The findings from this study may contribute to the development of more effective and safer regional anesthesia and analgesia protocols for this patient group.
Conducting this study will provide new insights into the optimization of anesthesia in pediatric spinal surgery, potentially leading to improved treatment outcomes and patient safety, as well as valuable data for clinical practice regarding the selection of anesthetic strategies.

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 19 Oct 2026; AzTrials last refreshed its copy on 7 Nov 2026.
