Quadro-Iliac Plane Block for Analgesia After Lumbar Microdiscectomy
Turkey (Türkiye)60 participantsStarted 2026-07-10
Plain-language summary
This study will evaluate whether ultrasound-guided quadro-iliac plane block provides better postoperative pain control than local infiltration analgesia in patients undergoing single-level lumbar microdiscectomy.
Adult patients scheduled for elective single-level lumbar microdiscectomy will be randomly assigned to receive either bilateral quadro-iliac plane block plus patient-controlled analgesia or local infiltration analgesia plus patient-controlled analgesia. The main outcome of the study will be total fentanyl consumption during the first 24 hours after surgery. Pain scores, need for rescue analgesia, opioid-related side effects, patient satisfaction, and recovery quality will also be evaluated.

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?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
