Pericapsular Nerve Group (PENG) Block on Pain During Participant Positioning for Spinal Anesthesia in Hip Fracture Surgery

Overview

Hip fracture surgery is a common orthopedic procedure, especially in elderly patients. These fractures are quite common in adults over the age of 65, and the one-year mortality rate ranges from 12% to 37%. Recent studies have suggested that general anesthesia and spinal anesthesia are not superior to each other in patients undergoing hip fracture surgery. Untreated/poorly managed perioperative pain is directly linked to delirium, poor prognosis, and secondary chronic pain in hip fracture patients. Therefore, considering the associated mortality, morbidity, and early recovery, control of perioperative pain should be one of the highest priorities of the anesthesiologist, regardless of the anesthesia method used.

Ultrasonography (USG)-guided regional anesthesia techniques are often used as part of multimodal analgesia in the management of perioperative pain in patients with hip fractures. One of the most recently described blocks used in hip fracture surgery, the USG-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, which selectively innervates the anterior aspect of the hip capsule. Case reports and a limited number of clinical studies have reported that PENG block is effective in managing acute fracture-related pain, neuraxial anesthesia positioning pain, and postoperative pain in hip fracture patients. In this study, investigators aimed to investigate the effect of USG-guided PENG block on positional pain before spinal anesthesia in patients undergoing surgery for hip fractures and to compare this effect with intravenous ketamine. In addition, investigators aimed to investigate the effect of PENG block on pain scores, perioperative opioid consumption, time to first analgesic requirement in the postoperative period, and quality of recovery in the first 24 hours after surgery.
