Interventions

This is a prospective, randomized, comparative, and double-blind clinical study with three groups. A total of 90 pediatric patients undergoing abdominal wall surgery will be randomly allocated to the

the second group will receive a Quadratus Lumborum (QL) Block administered between the quadratus lumborum muscle and the thoracolumbar fascia

and the third group will receive a Caudal Epidural Block (CEB) injected into the sacral epidural space. At the end of the surgery, residual neuromuscular blockade will be reversed with Sugammadex (4 m

Design outcomes

Primary

Measure	Time frame
To compare the total dose of rescue analgesics (dipyrone and nalbuphine), expressed in milligrams per kilogram (mg/kg), consumed by patients in the first 24 hours after the end of surgery, in order to assess the analgesic efficacy of the three blockade techniques under study	—

Secondary

Measure	Time frame
To assess pain intensity, measured by the FLACC (Face, Leg, Activity, Cry, Consolability) scale at different postoperative moments, and the duration of analgesia, recorded in hours. In addition, the proportion of patients who required rescue analgesia, the incidence of adverse effects, hemodynamic parameters, hospital stay duration in days, and the level of parental satisfaction with pain control will be recorded and analyzed	—
