Comparing Postoperative Pain Relief Using Quadratus Lumborum and Transversalis Fascia Blocks in Elective Inguinal Hernia Surgery

What this Trial Is About

Researchers are comparing the pain relief effects after surgery of two nerve block techniques the Transversalis Fascia Plane Block and the anterior Quadratus Lumborum Block. This study focuses on patients undergoing elective open inguinal hernia surgeries under spinal anesthesia. The goal is to assess which block delays the need for additional pain medication more effectively and improves postoperative comfort while reducing opioid side effects. Participants receive either the anterior Quadratus Lumborum Block or the Transversalis Fascia Block applied under ultrasound guidance after surgery while in a lateral position. Both blocks involve injecting 20 mL of 0.25% bupivacaine near specific muscles to block nerve signals. All patients have spinal anesthesia during surgery and receive paracetamol after the procedure. Pain scores, analgesic use, and side effects like nausea are monitored for 24 hours. During the study, patients are followed up at 2, 4, 8, 12, and 24 hours after surgery to measure pain levels using the Numeric Rating Scale and to record the time until first rescue pain medication is needed. Total opioid consumption and any postoperative side effects are tracked. Patients are monitored for 30 minutes after block administration, and rescue analgesics are provided if pain exceeds a certain level. The study aims to improve postoperative pain management and reduce opioid use after inguinal hernia surgery.
