Comparison of Postoperative Analgesic Effects of Quadro-iliac Plane Block and Transversus Abdominis Plane Blocks in Inguinal Hernia Surgery
Turkey (Türkiye)60 participantsStarted 2026-06-02
Plain-language summary
Inguinal hernia repair is one of the most commonly performed surgical procedures worldwide. Despite being classified as a minor surgical intervention, moderate to severe postoperative pain is reported in approximately 60% of patients. In a subset of these patients, acute postoperative pain may persist and evolve into chronic post-surgical inguinal pain, significantly affecting quality of life.
In recent years, beyond the use of systemic intravenous analgesics, ultrasound-guided fascial plane blocks have been increasingly incorporated into multimodal analgesia protocols with the aim of reducing postoperative opioid consumption and improving pain control. However, the current literature does not provide definitive evidence regarding the superiority of one block technique over another in this surgical population.
The primary objective of the present study is to compare the analgesic efficacy of the Quadro-iliac Plane Block (QIPB) and the transversus abdominis plane block (TAPB) in patients undergoing inguinal hernia repair.

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?
