Quadro-Iliac Plane Block Versus Wound Infiltration for Postoperative Pain After Single-Level Lumbar Discectomy
Turkey (Türkiye)60 participantsStarted 2025-12-01
Plain-language summary
This prospective observational study aims to compare the effects of the Quadro-Iliac Plane Block (QIPB) and wound infiltration (WI) on postoperative acute pain in adult patients undergoing elective single-level lumbar discectomy. QIPB is a newly introduced ultrasound-guided fascial plane block, and it is currently being used in routine clinical practice in our anesthesiology department as part of postoperative analgesia for lumbar spine surgery. Wound infiltration is a conventional method in which local anesthetic is injected into the surgical field at the end of the procedure.
In this study, eligible patients will be monitored prospectively without randomization or alteration of standard care. Postoperative pain scores, opioid consumption, nausea and vomiting, patient satisfaction, and recovery parameters will be evaluated during the first 24 hours after surgery. The study aims to provide real-world clinical evidence comparing these two analgesic techniques in lumbar discectomy patients.

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.
1This trial compared a nerve block called the Quadro-Iliac Plane Block against wound infiltration for pain after lumbar discectomy — can you explain what each of those approaches actually involves, and which one, if either, is already used here for my surgery?
2Since the main thing this trial measured was how much opioid painkiller patients needed in the first 24 hours after discectomy, what did the results suggest about whether one approach reduced opioid use more than the other, and does that matter for my recovery plan?
3Given that this study is already completed, are the findings published or available, and do they change how you'd recommend managing my pain after a single-level lumbar discectomy?
4Would either of these pain management techniques — the nerve block or the wound infiltration — be suitable for my specific situation, or are there reasons my case might make one of them less appropriate?
5If neither of these approaches is available at our facility, what is the standard pain management plan after lumbar discectomy, and how does it compare to what this trial was testing?

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?
