“A comparative study between Pericapsular nerve group block and Suprainguinal fasciailiaca compartment block for positioning patients with hip fractures before regional anesthesia"

Background and aims: Pain during positioning for neuraxial anesthesia in hip fracture patients remains a significant challenge. Ultrasound-guided regional nerve blocks are effective opioid-sparing techniques for improving positioning conditions. This study compared efficacy of ultrasound-guided Pericapsular Nerve Group (PENG) and Suprainguinal Fascia Iliaca Compartment (SIFI) blocks in hip surgical patients, using fast acting Lignocaine to facilitating positioning during regional anesthesia. Methods: In this double-blinded study, 70 patients with hip fractures were randomized into two groups : Group P (PENG block) and Group S (SIFI block), with 35 patients each. Pain was assessed using the Numerical Rating Scale (NRS) at rest and during 15° passive limb elevation at baseline, 10, 20, and 30 minutes post-block. Ease of spinal positioning (EOSP) at 30 minutes was the primary outcome. Secondary outcomes were to compare time to achieve adequate analgesia (NRS < 3) and requirement of rescue analgesia. Results: NRS scores significantly reduced post blockade in both groups. At 10 minutes, the SIFI group had statistically significant lower NRS during limb elevation than PENG group(p = 0.03) but scores were comparable at 20 and 30 minutes. EOSP scores were similar, with all patients achieving optimal positioning. Time to achieve NRS < 3 did not differ significantly with none requiring rescue analgesia. Conclusion: Both PENG and SIFI blocks provide effective analgesia at 30 minutes for positioning in hip fracture patients with SIFI block showing earlier dynamic pain relief. The use of Lignocaine adds practical advantage of faster block onset potentially improving turnover in busy settings.
