Comparison of the Postoperative Analgesic Efficacy of Quadratus Lumborum Block and Transversalis Fascia Block in Inguinal Hernia Surgery

What this Trial Is About

Researchers are evaluating the postoperative pain relief effectiveness of two types of nerve blocks, the Transversalis Fascia Plane Block and the anterior Quadratus Lumborum Block, in adults undergoing elective open inguinal hernia surgery. The study aims to compare how long it takes before patients need their first additional pain medication after surgery, as well as total pain relief medication use and pain scores over 24 hours. The goal is to improve pain management while reducing opioid-related side effects and supporting faster recovery. Participants will be randomly assigned to receive either the anterior Quadratus Lumborum Block or the Transversalis Fascia Plane Block after surgery. Both procedures involve injecting 20 mL of 0.25% bupivacaine guided by ultrasound while the patient is positioned on their side. All patients receive spinal anesthesia before surgery and a dose of intravenous paracetamol afterward. The nerve blocks are applied in a block room immediately post-surgery, with monitoring for 30 minutes following the procedure. Throughout the 24-hour period after surgery, patients will be assessed at 2, 4, 8, 12, and 24 hours to record pain levels using a Numeric Rating Scale, time to first use of additional pain medication, and total analgesic consumption. Side effects like nausea and vomiting will also be monitored. If pain scores exceed 3, rescue analgesics such as intravenous ibuprofen or dexketoprofen may be administered. This detailed follow-up helps determine which nerve block provides better pain control and fewer side effects to improve patient comfort and recovery.
