What this Trial Is About

This prospective clinical study aims to compare the postoperative analgesic efficacy of the ultrasound-guided transversalis fascia plane block (TFPB) and the transversus abdominis plane (TAP) block in pediatric patients undergoing laparoscopic surgery. Effective and long-lasting postoperative analgesia is essential for patient and parental satisfaction in pediatric anesthesia. With recent advances in ultrasound technology, regional anesthesia techniques have become increasingly utilized in pediatric practice. In the TAP block, local anesthetic is injected between the internal oblique and transversus abdominis muscles, providing analgesia typically between Torachal vertebra 10 (T10) and Lumbar vertebra (L1) dermatomes. The transversalis fascia plane block, developed as a modification of this approach, targets the proximal portions of the T12 and L1 nerves by depositing local anesthetic between the transversus abdominis muscle and the transversalis fascia, potentially offering wider sensory coverage. This study compares both blocks in terms of postoperative pain scores, duration of analgesia, and requirement for rescue analgesics in children undergoing laparoscopic surgery. The results are expected to contribute to the optimization of regional anesthesia techniques and improve pain management strategies in pediatric surgical patients.
