Quadro-iliac plane block versus TAP block for pain after inguinal hernia surgery
Official title: Comparison of Postoperative Analgesic Effects of Quadro-iliac Plane Block and Transversus Abdominis Plane Blocks in Inguinal Hernia Surgery
Run by Ankara Etlik City Hospital · NCT07442188 · Data updated 2026-11-12
In adults undergoing unilateral inguinal hernia repair, this study tests whether the Quadro-iliac Plane Block provides better postoperative pain relief than the Transversus Abdominis Plane Block.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults 18–65 with ASA I–III undergoing unilateral inguinal hernia repair under general anesthesia and with BMI 18–30 kg/m².
✕Probably not a fit
Patients outside the BMI or age ranges, those with higher surgical risk (ASA IV or higher), or those not receiving the QIPB may not experience additional pain relief.

What this trial studies
This interventional study compares two ultrasound-guided fascial plane blocks used for multimodal analgesia after unilateral inguinal hernia repair under general anesthesia. Participants are adults 18 to 65 with ASA I–III and BMI 18–30 kg/m². The primary goal is to see which block more effectively reduces postoperative pain and opioid use, with safety monitored throughout. The trial is conducted at Ankara Etlik City Hospital, with adults receiving one of the two regional blocks as part of their perioperative analgesia plan. Details on randomization, blinding, and study endpoints are not provided in the available information.
Why it matters
Potential benefit: If the QIPB proves superior, patients could experience better pain control and reduced need for opioid pain medicines after inguinal hernia surgery.
How similar studies have gone: Previous fascial plane block studies show variable benefits; this comparison addresses a relatively novel block (QIPB) against a more established TAP block.
