Riassunto dello studio

One hundred patients with hip fractures were randomized to receive either supra-inguinal fascia iliaca block (S-FIB) with 30 mL of 0.35% ropivacaine (n=50) or peri-capsular nerve group (PENG) block with 20 mL of 0.35% ropivacaine (n=50). The primary outcome was pain scores (numeric rating scale, NRS) at rest and during passive movement 30 minutes after nerve block. Secondary outcomes included pain scores at 10 and 20 minutes post-block, pain scores during positioning for spinal anesthesia, time required for nerve block and spinal anesthesia, and quality of positioning for spinal anesthesia. Overall, the results revealed no significant difference between the two groups in pain scores at 30 minutes. However, PENG block resulted in earlier pain relief at 20 minutes and required a shorter procedure time. These findings suggest that PENG block may be preferable due to its quicker onset and efficiency, despite similar analgesic efficacy at 30 minutes.
