Comparing the Pericapsular Nerve Group Block and the Lumbar Plexus Block for Hip Fracture Surgery: A Single-Center Randomized Double-Blinded Study.

Lumbar plexus blocks (LPBs) are routinely employed for analgesia in hip fracture surgery; however, a novel regional technique, the pericapsular nerve group (PENG) block, potentially offers comparable pain reduction while preserving motor function. Patients aged 45-90 years who underwent hip fracture surgery were allocated to receive either a PENG block or an LPB for analgesia. The primary outcome was the incidence of quadriceps motor block (defined as the paresis or paralysis of the knee extension) at 12 h postoperatively. The secondary outcomes included the performance time, the time to first analgesic requirement, postoperative intravenous (IV) fentanyl consumption, the ability to undergo physiotherapy at 24 and 48 h, complications, sensory and motor block assessments, postoperative numeric rating scale (NRS) pain scores, and patient outcome questionnaires. There was a significantly lower incidence of quadriceps motor block at 6 h (26.7% vs. 80.0%; p < 0.001) and at 12 h (20.0% vs. 56.7%; p = 0.010). The PENG block provided better preservation of the sensory block as well as better performance time ( p < 0.001) and time to first analgesia requirement ( p = 0.034), whereas the LPB resulted in lower postoperative IV fentanyl consumption at 24 h ( p = 0.013). The PENG block demonstrated superiority over the LPB in preserving quadriceps strength and patient satisfaction without any substantial complications, despite higher opioid consumption within the first 24 h post-surgery.
