Exclusion criteria: 1. Allergy to ropivacaine or dexmedetomidine. 2. Contraindications to regional anesthesia 3. Pre-existing chronic pain conditions. 4. Severe hepatic or renal impairment 5. Cognitive impairment or inability to comply with pain assessments. 6. Refusal to participate

Design outcomes

Primary

Measure	Time frame
To determine whether dexmedetomidine-adjuvanted ropivacaine in ultrasound-guided PENG block significantly prolongs the duration of analgesia compared to plain ropivacaine in hip surgery patients. Timepoint: 24 hours	—

Secondary

Measure	Time frame
1. To compare the total analgesic consumption between the two groups in the first 24 hours post-block and need for first rescue analgesia 2. To assess differences in pain scores (using the Numeric Rating Scale, NRS) at 0, 2 , 4, 6, 12, 24 hours post-block 3. To investigate the impact of the PENG block on patient satisfaction using Likert scale. 4. To compare hemodynamic parameters 5.To evaluate the incidence of adverse eventsTimepoint: 24 hours	—
