Perioperative analgesia with combined Pericapsular Nerve Group (PENG) and lateral femoral cutaneous nerve blocks in pediatric femoral neck surgery: a two-case report

BACKGROUND: The importance of regional anesthesia techniques is increasing as part of multimodal analgesia strategies for managing postoperative pain in pediatric hip and femur surgeries. CASE PRESENTATION: We aim to present two cases, aged 10 years and 18 months, scheduled for surgery due to femoral neck fractures. As part of multimodal pain management, ultrasound-guided PENG + LFCN blocks were performed in both cases. Postoperative pain was assessed using VAS and FLACC scales. CONCLUSIONS: Our observations in these two cases suggest that the combined administration of PENG and LFCN blocks may serve as a valuable adjunctive strategy in the multimodal analgesia management of pediatric femoral neck fractures. Nevertheless, further large-scale clinical studies are warranted to more clearly delineate the efficacy and safety profile of this combination in routine clinical practice.
