Efficacy of Ultrasound-guided Sacral Multifidus Plane Block as Perioperative Analgesia for Anal and Penile Surgeries in High-risk Pediatric Patients

Effective postoperative pain control in pediatric patients remains a major concern, particularly in those undergoing anal, perineal and penile surgeries. Inadequate analgesia is associated with delayed recovery, increased stress response, prolonged hospitalisation, and higher postoperative morbidity. This study aims to evaluate the efficacy of ultrasound-guided sacral multifidus plane block as a method for perioperative analgesia in high-risk pediatric patients undergoing anorectal and penile surgeries, to reduce the risks associated with systemic analgesia. This involves the administration of local anesthetics in the plane between the sacral multifidus muscle and the intermediate sacral crest bilaterally.
