Summary

To compare the efficacy and safety of ultrasound-guided ESPB versus QLB for post-operative analgesia in children undergoing kidney surgery.

Conditions

Interventions

PROCEDURE

Quadratus lumborum block teqnique

All blocks were performed under ultrasound guidance. A high-frequency linear probe was positioned in the mid-axillary line cranial to the iliac crest to identify the abdominal wall muscles (external oblique, internal oblique, and transversus abdominis). The probe was then moved dorsally until the transversus abdominis muscle became aponeurotic, which was followed medially to visualize the quadratus lumborum (QL) muscle at its attachment to the L4 transverse process adjacent to the psoas muscle. Using an in-plane anterior-to-posterior approach, the block needle was advanced toward the anterior border of the QL muscle. After confirming the needle tip position with a 1 ml saline test injection, 0.5 ml/kg of 0.25% bupivacaine was administered. Bilateral injections were performed for midline incisions, while unilateral injections were used for paramedian incisions.

PROCEDURE

Erector spinae plane block Technique

Ultrasound-guided erector spinae plane block performed at the thoracic level using a single-shot technique in pediatric patients undergoing kidney surgery to provide postoperative analgesia. Local anesthetic is injected deep to the erector spinae muscle over the transverse process with expected craniocaudal spread.
