Abstract

Objectives: To evaluate the analgesic efficacy of ultrasound-guided pericapsular nerve group (PENG) block in facilitating patient positioning for spinal anesthesia in femoral neck fractures. Methods: A prospective, descriptive study was conducted on 20 patients with femoral neck or intertrochanteric fractures who underwent surgery at Hai Phong Medical University Hospital from December 2024 to June 2025. Results: The PENG block facilitated optimal patient positioning by significantly reducing pain during hip flexion and rotation, which had previously been the most painful movements. The Visual Analogue Scale (VAS) pain score during positioning for spinal anesthesia was 1.2 ± 0.7, a significant decrease from the pre-block VAS score during movement (8.7 ± 0.7). At the time of the procedure, 18 out of 20 patients (90%) were able to assume the lateral decubitus position with spinal flexion without assistance. One 85-year-old female patient required slight assistance to maintain the position. No procedure-related adverse events or complications were observed during or after the procedure. Conclusion: Ultrasound-guided PENG block offers effective analgesia during preoperative positioning for spinal anaesthesia in patients with intertrochanteric or femoral neck fractures. No complications or adverse events were observed. Further large-scale, comparative studies are warranted to confirm the efficacy and superiority of PENG block over conventional regional anesthesia.
