Periarticular Infiltration of Local Anesthetics Versus Pericapsular Nerve Group Block for Total Hip Replacement

After the ultrasound-guided insertion of a block needle at the level of the inguinal ligament, the needle will be advance into the plane between the iliac bone periosteum and the tendon of the iliopsoas muscle in order to inject 20 mL of adrenalized 0.5% bupivacaine.

Intraoperatively, 60 mL of adrenalized 0.25% bupivacaine plus ketorolac 30 mg will be infiltrated by the surgeon.
