CHRONIC PAIN, SECONDARY
Hip fracture surgery is a common orthopedic procedure, especially in elderly patients [Untreated/poorly managed perioperative pain is directly linked to delirium, bad prognosis, and secondary chronic pain in hip fracture patients [Ultrasonography-guided (US-guided) regional anesthesia techniques are frequently used as part of a multimodal plan in the management of perioperative pain in patients with hip fractures. One of the most recently described blocks used in hip fracture surgery, US-guided pericapsular nerve group (PENG) block aims to directly block the articular branch of the femoral nerve, the articular branch of the obturator nerve and the accessory obturator nerve that selectively innervate the anterior aspect of the hip capsule [Herein we investigate the effect of US-guided PENG block on positioning pain and compare that effect to intravenous opioid (fentanyl) in patients undergoing surgery under spinal anesthesia for a fractured hip. Additionally, we sought to investigate the effect of PENG block on pain scores, opioid intake, time to first analgesic requirement, and quality of recovery within the first 24 h following surgery.
