Quadro-Iliac Plane Block for Postoperative Analgesia in Laparoscopic Inguinal Hernia Repair
Sponsor: Marmara University Pendik Training and Research Hospital
Summary
The goal of this randomized controlled trial is to learn whether an ultrasound-guided quadro-iliac plane block (QIPB) reduces opioid use and pain after laparoscopic inguinal hernia repair in adults aged 18-65 years. The main question it aims to answer is: does QIPB reduce total tramadol consumption during the first 24 postoperative hours? Researchers will compare patients who receive QIPB under general anesthesia with patients who receive no block. All participants will receive the same general anesthesia, multimodal analgesia and intravenous tramadol patient-controlled analgesia (PCA). Pain scores, PCA use, quality of recovery (QoR-15), nausea and vomiting, and time to discharge will be recorded during the first 24 hours.

Interventions
Quadro-iliac plane block
With the patient in the lateral position, a low-frequency convex probe is placed parasagittally at the attachment of the quadratus lumborum to the iliac crest. Using an in-plane approach with a 100-mm block needle, position is confirmed with 5 mL saline, followed by 40 mL of 0.25% bupivacaine.
