Comparison of analgesic effect of pericapsular nerve group block and supra-inguinal fascia iliaca compartment block on dynamic pain in patients with hip fractures: a randomized controlled trial

Patients with hip fracture often experience severe pain, particularly during movement or slight positional change, prior to the occurrence of surgery. It is essential to explore the appropriate analgesic methods before surgery in patients with hip fracture, especially those capable of alleviating dynamic pain. Pericapsular nerve group (PENG) block was introduced as a useful technique for hip analgesia. In this study, we aimed to compare the reduction in dynamic pain between the PENG block and supra-inguinal fascia iliaca compartment block (SIFICB).
