Bupivacaine In Pericapsular Nerve Group Block During Hip Fracture Surgery .
Evaluation of two doses (20 mL and 15 mL) of 0.25% bupivacaine in pericapsular nerve group block for patient positioning for sub-arachnoid block during hip fracture surgery: A single-centre, randomised comparative trial.
Indian J Anaesth . 2024 Apr;68(4):323-328.Sixty patients aged 40–90 years with hip fractures were randomized to receive either 20 mL (n=30) or 15 mL (n=30) of 0.25% bupivacaine through a pericapsular nerve group (PENG) block before sub-arachnoid block (SAB). The primary outcome was the ease of positioning (EOP) for SAB, graded from unsatisfactory to optimal. Secondary outcomes included verbal analogue scale (VAS) pain scores at rest and during a 15° leg raise at baseline, 10 minutes, and 20 minutes post-block. Outcomes were assessed over 20 minutes post-block. Overall, 20 mL of bupivacaine significantly improved EOP (P=0.001) and reduced VAS pain scores more effectively than 15 mL. These findings suggest that 20 mL provides superior analgesia and patient positioning support for SAB.
