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.

Appendicectomy is amongst the most commonly performed surgery, with acute appendicitis being the most frequent reason for abdominal surgical emergencies in the world . The lifetime risk of appendicitis is 7-8%, with rising incidence in the newly industrialized countries . The prevailing treatment of choice for appendicitis is appendicectomy, which can be performed either 'open' or laparoscopically . A major contributor to the pain experienced by a patient after abdominal surgery is the incision made in the abdominal wall . Almost 80% of patients undergoing surgery experience postoperative pain, and 80% of them reported moderate-to-severe pain intensity . Traditional methods of postoperative pain management in children, such as systemic opioids and nonsteroidal anti-inflammatory drugs , may not always provide adequate relief, especially for more invasive procedures . These approaches can also be associated with side effects like sedation, nausea, and respiratory depression, which may complicate postoperative care and recovery . In recent years, regional anesthesia techniques have emerged as promising alternatives for postoperative pain management in various surgical populations Two specific regional blocks that have gained attention for their potential benefits in reducing postoperative pain after abdominal surgeries is the Quadratus Lumborum Block and the Transversus Facial Abdominal Plane block The Quadratus Lumborum Block targets the nerves supplying the lumbar plexus, providing analgesia to the anterior abdominal wall . It has been shown to be effective in adult patients undergoing lower abdominal surgery, offering improved postoperative pain scores and reduced opioid consumption compared to traditional pain management strategies . Although, both Quadratus Lumborum Block and Transversus Facial Abdominal Plane block are frequently employed in pediatric anesthesia, evidence to guide clinical decisions on which block offers superior outcomes needs to be comprehensively reviewed. We aimed to compare the effectiveness of ultrasound-guided Transversalis Fascia Plane block versus Quadratus Lumborum block for postoperative pain relief in pediatrics undergoing appendectomy.
