Assessment of PENG Block Analgesia Versus Intra-articular Infiltration in Hip Prosthesis Surgery

After hip arthroplasty, pain intensity is maximum within the first 6 hours and is then estimated to last between 36 and 72 hours. Pain management (analgesia) after hip prosthetic surgery remains a challenge. A bad analgesic treatment can result in delay in mobilization/ambulation and thus increase duration of patient's stay which can have a significant economic impact. The different recognized analgesia techniques (intra-articular infiltration and peripheral nerve blocks) are effective but have shown certain limits. A new peripheral nerve block, the PENG block has shown very encouraging results on postoperative analgesia quality. In this context, this research is based on the hypothesis that ultrasound-guided PENG block could provide more effective analgesia than intra-articular infiltration during mini-invasive anterior hip prosthesis surgery.
