Quality Of Recovery After Pericapsular Nerve Group (PENG) Block For Hip Hemiarthroplasty Under Spinal Anesthesia

The PENG block will be performed with the patient in the supine position. A linear high-frequency ultrasound probe (GE LOGIQ/P7 ultrasound, korea/ L6-12RS probe) is initially placed in a transverse plane over the anterior inferior iliac spine (AIIS); the probe is turned slightly medial until the hyperechoic continuous shadow of the iliopubic eminence (IPE). The target will be the plane between the psoas tendon and pubic ramus. The skin puncture site will be anesthetized using lidocaine 2% after skin disinfection and draping. A 22-gauge, 100 mm echogenic needle (Spinocan, B. Braun Melsungen AG, Germany) will be inserted in an in-plane approach to place the tip in the musculofascial plane between the psoas tendon anteriorly and the pubic ramus posteriorly. Following negative aspiration, 25 mL of the local anesthetic solution (bupivacaine 0.5%) was injected in 5 mL increments while observing for adequate fluid spread in this plane.
