Analgesic Comparison of Transversus Fascial Plane and Quadratus Lumborum Blocks in Pediatric Urogenital Procedures

This study aims to compare the analgesic effectiveness of the preoperatively administered Anterior Quadratus Lumborum Block (Anterior QLB) and the Transversalis Fascia Plane Block (TFP block) in children undergoing lower abdominal urogenital surgery. The study will include children aged 6 months to 12 years, with randomization performed using the sealed opaque envelope method, and outcome assessment conducted in a double-blinded manner. All patients will receive a standardized anesthesia protocol, and the regional blocks will be performed under ultrasound (US)-guided techniques. Perioperative evaluations will include pain levels, hemodynamic responses, additional analgesic requirements, block performance time, technical success rate, and family satisfaction. Postoperative pain will be monitored using the Face, Legs, Activity, Cry, Consolability (FLACC) scale, and analgesics will be administered when necessary. By comparing these two commonly used regional anesthesia techniques, this study aims to contribute to improved perioperative pain management strategies in the pediatric population.
