Study Arms (2)

QLB

ACTIVE COMPARATOR

The patient is in the prone position, an ultrasound probe is placed in a transverse, oblique, and paramedian orientation approximately lateral to the posterior axillary line. The needle is then inserted in-plane from the medial side of the transducer and advanced laterally to enter the interfascial plane between the Quadratus Lumborum muscle and the kidney. We confirmed that the local anesthetic appeared to press down the kidney in the ultrasound image

Procedure: Subcostal Oblique Quadratus Lumborum Block and Erector Spinae Plain Block.

ESPB

ACTIVE COMPARATOR

Using aseptic technique, an ultrasound probe is placed at the T9 vertebral level. After identifying the ribs and sliding towards the midline in a longitudinal parasagittal orientation, the overlying Erector Spinae is identified by visualization of the transition between the rib and transverse apophysis a block needle is inserted in plane with ultrasound beam and is advanced in a cephalo-caudal direction until the tip contacted the transverse process.

Procedure: Subcostal Oblique Quadratus Lumborum Block and Erector Spinae Plain Block.

Interventions

patients undergo general anesthesia,will be put in prone position.In case of Quadratus Lumborum block 1-3 mL of normal saline is injected to produce hydro-dissection and spread cranially between the QL and kidney. The corresponding ultrasonographic sign is a lunar-shaped hypo-echoic fluid collection observed between the long axis of the kidney and QL muscle. 20 ml Bupivacaine 0.5%, 10 ml Lidocaine 2%, and 10 ml normal saline is administered. In case of the ESPB The location of the needle tip is confirmed by hydro-dissection and after visualizing the fluid spread lifting the Erector Spinae off the transverse process, 20 ml bupivacaine 0.5%, 10 ml Lidocaine 2%, and 10 ml normal saline is injected.
