This study aims to compare the effectiveness of ultrasound-guided Transversalis Fascia Plane block versus Quadratus Lumborum block for postoperative pain relief in pediatrics undergoing appendectomy.
Primary outcomes:
• Proportion of patients needing rescue analgesia within the first 24 postoperative hours.
Secondary outcomes:
* Visual Analogue Scale pain intensity measurements.
* Intraoperative Heart rate and mean arterial blood pressure will be recorded.
* Time to first analgesic request for patients needing rescue analgesia (Fentanyl).
* Block-related complications (e.g., hematoma, local anesthetic toxicity, lower limb weakness).
* Parents' satisfaction score.
