Comparison Between Bupivacaine-Dexmedetomidine Versus Bupivacaine-Dexamethasone in Pericapsular Nerve Group (PENG) Block

The PENG block will be performed ,the patient is placed in the supine position , the procedural leg is slightly abducted, the curvilinear low-frequency ultrasound probe will be placed over the line parallel to the inguinal ligament. It will subsequently rotated 45◦ to identify the anterior inferior iliac spine, the iliopubic eminence, and the psoas tendon. A 22-gauge, 80 mm echogenic needle will inserted in an in-plane approach to place the tip in the musculofascial plane between the pubic ramus posteriorly and the psoas tendon anteriorly. Following negative aspiration, by one of the two syringes each one has a serial number corresponding to each group.
