Erector Spinea Plane Block in Pediatric Hip Surgery

"ESP block will be performed with the patient lying in the lateral position and the surgical side at the top. After skin disinfection, sterile draping will be placed, and ultrasound probe will be sheathed. The level of the block will be at the transverse process of L2, using a 9-12 MHz linear probe and placed in a parasagittal plane 1 cm from the posterior midline. The deep plane to the erector spinae muscle (ESM) will be identified and a 22 Gauge 50 mm insulated needle will be inserted craniocaudally in plane between the transverse process and the fascia of the ESM.~After negative aspiration, 0.3 mL/kg- of bupivacaine 0.25% will be injected confirming correct position by visualizing the solution lifting the ESM off the transverse process .Spread of LA between the L1 and L4 transverse processes will be thereafter visually tracked with the transducer. In the control group, no local anesthetics will be injected."
