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

Patients undergoing hip hemiarthroplasty can benefit significantly from regional anesthesia in terms of pain management and recovery . There is a wide range of regional anesthetic techniques. The most common in this anatomical region and those with the greatest published research are fascia iliac block, lumbar plexus block, and femoral nerve block . Alternative methods include lateral femoral cutaneous nerve and selective obturator nerve infiltration blocks. Novel techniques, including local infiltration analgesia and quadratus lumborum block, have been reported. While femoral nerve and lumbar plexus blocks are two common opioid-sparing regional anesthetic procedures that are successful, they come with a risk of undesired lower limb muscle weakness . On the other hand, the fascia iliac block does not always offer sufficient pain relief following hip surgery. The important landmarks targeted on the hip joint branches from the femoral nerve and the auxiliary obturator nerve may now be identified thanks to a recent anatomical study on hip innervation . This led to the discovery of a novel localized anesthetic treatment termed pericapsular nerve group block (PENG), which blocks these nerves to target the hip's anterior capsule. The PENG block has been suggested as a successful motor-sparing block for hip hemiarthroplasty . The objective of the current study is to evaluate the efficacy of the pericapsular nerve group block (PENG) for the reduction of opioid consumption and management of postoperative pain after hip hemiarthroplasty.
