{Abstract}: <B>UNASSIGNED: </B>Femoral nerve block is a widely used analgesia technique for positioning before spinal anaesthesia for proximal femur fracture surgeries. Pericapsular nerve group (PENG) block is a newer technique with motor-sparing characteristics. We compared the analgesic efficacy of these blocks for patient positioning for spinal anaesthesia.<BR><B>UNASSIGNED: </B>In this study, 60 patients were randomised to either the PENG group (n = 30) or the femoral group (n = 30). After performing the block, the pain was assessed every 10 min using a visual analogue scale (VAS) score for 30 min. The primary objective was the median [interquartile range (IQR)] reduction in pain (dynamic VAS with 15-degree passive limb elevation) at 30 min. Secondary objectives were ease of spinal position score (EOSP), angle obtained during positioning, duration of postoperative analgesia and quadriceps weakness.<BR><B>UNASSIGNED: </B>The demographics were comparable in both groups. After 30 min, the median (IQR) VAS was 6 (5-7) in the PENG group and 5 (5-6) in the femoral group (P = 0.004). Secondary outcomes such as EOSP score and angle obtained by patients were comparable. In the postoperative period, patients had significantly lower pain in the PENG group compared to the femoral group. The duration of analgesia was prolonged with PENG block. Quadriceps weakness was significantly low with PENG block (P < 0.001).<BR><B>UNASSIGNED: </B>PENG block provides better analgesia than a femoral block before spinal anaesthesia for proximal femur fracture surgery. The postoperative duration of analgesia was also longer.
