Experimental: Quadratus Lumborum block group Quadratus Lumborum block group (QL) patients will receive a bilateral Quadratus Lumborum block using Ropivacaine 0.375%
Ultrasound-guided continuous ESP block with opioid PCA A high-frequency linear ultrasound transducer will be placed in a longitudinal parasagittal orientation 3 cm lateral to the T7/T8 spinous process. A Contiplex Echo ultra 360 18G needle with 20G × 55 cm Contiplex Echo catheter will be inserted using an in-plane superior-to-inferior approach to place the tip into the fascial plane on the deep (anterior) aspect of erector spinae muscle. The location of the needle tip will be confirmed by visible fluid spread lifting erector spinae muscle off the bony shadow of the transverse process. A total of 30 mL of 0.375% ropivacaine
