Laparoscopic abdominal surgeries are frequently performed in pediatric patients and are often associated with significant postoperative pain, which, if inadequately managed, may delay recovery and increase the risk of chronic pain. Optimal analgesia is therefore essential. Regional anesthesia techniques have gained prominence for their ability to provide targeted pain relief, reduce systemic analgesic requirements, and improve recovery outcomes. Among these, the MTAPA through the Perichondral Approach (MTAPA) and the ESPB have attracted attention for potential pediatric use. MTAPA, a refinement of the traditional TAPA, targets thoracoabdominal and lower intercostal nerves, offering effective abdominal wall analgesia. Its perichondral approach aims to enhance local anesthetic spread, potentially improving postoperative pain control. ESPB involves depositing local anesthetic between the erector spinae muscle and vertebral transverse processes, producing analgesia through dorsal and ventral rami blockade. Though widely applied in various surgeries, its role in pediatric laparoscopic abdominal procedures is less studied. MTAPA covers a broader dermatomal range than techniques such as the Transversus Abdominis Plane (TAP) or Oblique Subcostal TAP block, particularly for anterior dermatomes, though most adult reports note coverage between T6-T12. Both MTAPA and ESPB have shown promise in adults, yet their comparative efficacy in pediatric laparoscopic abdominal surgeries remains unclear. This study aims to address this knowledge gap. Therefore, this study aimed to compare the effectiveness of the ESPB and the MTAPA in providing postoperative analgesia for pediatric patients undergoing laparoscopic abdominal surgeries. The study was prospective randomized double blinded comparative and was conducted on 50 patients. They were divided into two equal groups: group (A): they received MTAPA block after induction of GA and group (B): they received ESPB after induction of GA. The study will be double blinded in which the patients, and outcome assessors involved will be blinded to the study allocation and outcomes. Patients received GA induction via propofol 1.5-2.5 mg/kg, fentanyl 1 µg/kg and the maintenance dose were sevoflurane 2%, Tracrium 0.03 mg/kg.
