Effect of Preoperative PENG Block on Spinal Anesthesia Positioning and Postoperative Analgesia in Hip Fracture Surgery

A single-shot PENG block was administered preoperatively using ultrasound guidance. The block was performed with the patient in the supine position, and 20 mL of local anesthetic (0.25% bupivacaine) was injected between the psoas tendon and the superior pubic ramus to achieve analgesia of the anterior hip capsule.

Patients in this arm were managed according to standard care protocols for spinal anesthesia in hip fracture surgery. No preoperative regional block was performed. Pain scores and postoperative tramadol use were measured for comparison with the experimental arm.
