Conditions
Summary
This randomized controlled trial aims to compare the postoperative analgesic efficacy of ultrasound-guided Sacral Erector Spinae Plane (ESP) block versus Dorsal Penile Nerve Block (DPNB) in pediatric patients aged 1-7 years undergoing hypospadias surgery. The primary outcome is the pain score assessed by the FLACC scale at the 12th postoperative hour

Interventions
Patients will be placed in the lateral decubitus position. Under ultrasound guidance, the plane between the multifidus muscle and the sacral lamina (erector spinae plane) will be identified at the sacral level. A total of 0.4 mL/kg of 0.25% Bupivacaine will be injected bilaterally
Patients will be in the supine position. Under ultrasound guidance, the needle will be advanced under Buck's fascia at the penile base (pubic symphysis level). A total of 0.4 mL/kg of 0.25% Bupivacaine will be injected bilaterally
