Postoperative pain management has an important place in anesthesia practices. In order to ensure patient comfort after the surgery, to start postoperative rehabilitation early, and to prevent the process from causing mood disorders such as anxiety and pathological conditions such as chronic pain syndrome, the pain caused by the operation in the postoperative period must be effectively relieved. Pericapsular nerve group (PENG) block; It is a regional anesthesia technique that targets the anterior capsule of the hip joint and aims to block the joint branches of the accessory obturator nerve and femoral nerve by administering local anesthetic. Although it has been described recently, controlled prospective studies in the literature have shown it to be a safe and effective regional technique for postoperative pain after hip surgery. However, volume studies on this block are limited. Therefore, in this study, we aimed to determine the optimal dose by comparing the effectiveness of PENG block on pain using different local anesthetic volumes.
