TIPS Block vs Dual Subsartorial Block

"Drug: Bupivacaine 0.25 % mixed with 2 mg dexamethasone.~Patients will receive a third injection of 10 ml of 0.25 % bupivacaine superficial to the sartorius under the facia lata"

"Drug: Bupivacaine 0.25 % mixed with 2 mg dexamethasone~Patients will receive a combination of femoral triangle block and distal ACB."

Femoral triangle block will be given just (1-2 cm) proximal to the apex of the femoral tringle which is the point at which the medial border of the sartorius muscle (STM) meets the medial border of the adductor longus muscle (ALM). Ten ml of 0.25 % bupivacaine mixed with 2 mg dexamethasone will be injected just below the STM.

Another 20 ml of 0.25 % bupivacaine mixed with 2 mg dexamethasone will be injected in the lower one-third of the adductor canal.

Patients will receive a third injection of 10 ml of 0.25 % bupivacaine superficial to the sartorius under the facia lata
