Interventions
Patients will be placed in the lateral decubitus position. Under ultrasound guidance, the probe will be placed at the posterior axillary line. The needle will be advanced to the posterior fascial plane of the quadratus lumborum muscle. A total of 0.5 mL/kg of 0.25% Bupivacaine will be injected.
Patients will be placed in the lateral decubitus position. Under ultrasound guidance, the probe will be placed at the level of the iliac crest. The needle will be targeted to the plane where the quadratus lumborum muscle attaches to the iliac bone. A total of 0.5 mL/kg of 0.25% Bupivacaine will be injected
