Ultrasound Percapsular Nerve Group Block VS Fascia Iliaca Block for Hip Fracture

Spinal anesthesia (SA) is a widely accepted anesthetic technique for hip fracture repair among elderly. Positioning for SA can be extremely painful. Effective management of pain is important for these patients comfort. Fascia Iliaca block (FIB) and Femoral nerve blocks are commonly used for analgesia in hip fracture patients. However, they often provide a modest reduction in pain. The Percapsular Nerve Group block (PENG Block) has the advantage that it covers the accessory obturator nerve. Aim of the study: compare FIB with PENG prior to positioning hip fracture patients for standardized SA. In a prospective randomized double blind we included 80 patients aged more than 65 years old, for whom pain was felt when raising the affected limb to 15 degrees. Patients were assigned to receive either ultrasound guided Fascia Iliaca block or Percapsular Nerve Group block using 20 mL Lidocaine 1.5% in both groups. We compared pain on positioning for spinal anesthesia using Verbal Rating Scale (VRS 0 = no pain , VRS 1 = mild pain, t 2= severe pain) for both groups. We also recorded different times to perfom block.
