The Effect of Different Volumes of Ilioinguinal-Iliohypogastric Nerve Block on Postoperative Analgesia in Inguinal Hernia Surgery
70 participantsStarted 2026-04-14
Plain-language summary
The primary objective of this study is to evaluate and compare the efficacy of different volumes of local anesthetics, administered at the same total dose, for ilioinguinal and iliohypogastric (II/IH) nerve blocks in patients undergoing unilateral inguinal hernia repair.
The investigators aim to determine whether varying the injectate volume-while keeping the total drug amount constant-influences the quality and duration of postoperative analgesia. By monitoring pain scores and opioid consumption, this research seeks to identify the optimal volume-to-dose ratio for enhancing patient recovery and pain management following inguinal surgery.

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 is comparing different volumes of a nerve block injection used during inguinal hernia surgery — can you explain how the volume of that block might affect my pain control after the operation?
2Since this trial hasn't started recruiting yet, what does that mean for my timeline if I'm interested in being considered for it, and would waiting affect my hernia treatment plan?
3The trial is measuring how long it takes before patients need their first rescue pain medication after surgery — based on your experience, how does a nerve block like this typically compare to the pain management approach you'd use for my surgery right now?
4This study is listed as Phase NA, which often applies to procedural or technique-based research rather than drug trials — does that change what we know about the safety of trying different block volumes, and are there any risks I should be aware of?
5If I don't participate in this trial, what pain management plan would you recommend for my inguinal hernia surgery, and how does it compare to what's being tested here?
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.
What they're measuring
1
Time to first rescue analgesic requirement.
Timeframe: Up to 24 hours postoperatively.
