What this Trial Is About
Researchers are studying pain management techniques for patients undergoing inguinal hernia repair, a common surgical procedure. Despite being classified as minor surgery, many patients experience moderate to severe pain after the operation, with some developing chronic pain that impacts their quality of life. This study aims to compare two ultrasound-guided nerve block techniques, the Quadro-iliac Plane Block (QIPB) and the transversus abdominis plane block (TAPB), to see which provides better pain relief. Participants will be randomly assigned to receive either the TAPB or QIPB procedure under ultrasound guidance during their hernia surgery. Both procedures involve injecting 30 ml of 0.25% bupivacaine to block pain signals, with TAPB performed while lying on the back and QIPB while lying on the side. These blocks are intended to be part of multimodal pain control during and after surgery. During the study, researchers will monitor pain scores for up to 24 hours after surgery and assess patient satisfaction at the 24-hour mark. Patients will be observed in a controlled setting during and after the procedure to evaluate the effectiveness of each nerve block. The study includes adults aged 18 to 65 undergoing unilateral inguinal hernia repair under general anesthesia, and participation lasts through the immediate postoperative period.
