PENG Block: A superior alternative for pain management in intracapsular hip fractures.

Background and Objectives: Previous studies have demonstrated the effectiveness of regional analgesic techniques for pain management after hip surgery; however, no clear superiority between these techniques has been established. A key limitation of these studies is the lack of differentiation between fracture subtypes. This prospective, comparative cohort study aims to evaluate the effectiveness of two regional techniques-pericapsular nerve group block (PENG) and suprainguinal iliac fascia block (FICB)-in providing perisurgical analgesia for intracapsular femoral fractures. Materials and Methods: Sixty-four patients undergoing elective surgery for intracapsular femoral fractures were randomly assigned to receive either a PENG block or an FICB block, each with 15 mL of 0.2% ropivacaine. Intradural anesthesia and conventional intravenous analgesia were administered during surgery. The primary outcome was pain scores in the recovery room and 24 hours post-surgery. Secondary outcomes included the need for intravenous opioid rescue medication during the first 24 hours. Results: The PENG group demonstrated significantly lower postoperative pain scores compared to the FICB group both immediately after surgery ( Conclusions: The PENG block provides superior postoperative analgesia for intracapsular femoral fractures compared to the FICB block following hip surgery, with reduced opioid consumption observed in the PENG group.
