Comparison of PENG Block and FICB in Hip Fracture Patients

Comparison of Analgesic Effect of Pericapsular Nerve Group Block and Suprainguinal Fascia Iliaca Compartment Block on Dynamic Pain in Patients Undergoing Hip Fracture Surgery: a Randomized Controlled Trial

Fascia iliaca compartment block (FICB) has been considered the block of choice for patients with hip fracture. However, pericapsular nerve group (PENG) block, one of the relatively newly-developed blocks, could be also used for analgesia in patients with hip fracture. Since PENG block could block the accessory obturator nerve, PENG block might have greater analgesic effects compared to FICB theoretically. However, the comparison of these two blocks in patients with hip fracture has not performed in clinical setting. Thus, we aimed to compare the analgesic effect of PENG block and FICB.
