This retrospective study evaluates the effects of two different administration methods of the Pericapsular Nerve Group (PENG) Block on postoperative pain control, opioid consumption, and recovery in patients undergoing hip surgery. All patients in the study received: * PENG block via a catheter * Patient-Controlled Analgesia (PCA) with tramadol * Multimodal analgesia, including IV paracetamol and nonsteroidal anti inflammatory drugs (NSAIDs) as rescue analgesia The study compares two groups: 1. Intermittent Bolus Group: A researcher administered 20 mL of 0.25% bupivacaine every 4 hours. 2. Continuous Infusion Group: A pump delivered 5 mL/hour of 0.25% bupivacaine continuously. Both groups received the same total volume of local anesthetic over 24 hours. All PENG blocks were performed under ultrasound guidance at the end of surgery. This study aims to determine whether intermittent bolus or continuous infusion PENG block administration leads to better pain control, lower opioid consumption, and improved recovery outcomes.
