SII Levels Following PENG Block in Pediatric Hip Surgery
Poland100 participantsStarted 2026-06-01
Plain-language summary
This study is a prospective, randomized, double-blind clinical trial. Its aim is to evaluate whether adding a pericapsular nerve group (PENG) block to spinal anesthesia can reduce the inflammatory response after hip surgery in children.
Hip surgery in children can cause a strong stress and inflammatory reaction, which may affect pain after surgery, the need for opioid medications, and recovery.
Children aged 3 to 8 years will be randomly assigned to one of two groups: spinal anesthesia alone or spinal anesthesia combined with a PENG block. The main goal is to compare changes in the Systemic Immune-Inflammation Index (SII), a blood-based marker of inflammation, measured before surgery and 24 hours after surgery.
Additional outcomes include other inflammatory markers, postoperative pain, opioid use, time to first rescue pain medication, and side effects.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
