biostudies-literatureUnknown24(1)Wu H<h4>Background</h4>As a fascial plane block technique, further exploration is needed to determine the safety and efficacy of a peri-capsular nerve group (PENG) block in elderly patients with intertrochanteric femur fractures. We aimed to evaluate whether opioid consumption during a PENG block is better than a conventional opioid-based program for postoperative pain management after proximal femoral nail anti-rotation (PFNA).<h4>Methods</h4>We conducted a prospective, randomized, controlled trial comparing the efficacy of the PENG block with the control group for elderly patients undergoing primary PFNA under general anesthesia. The primary outcome was the cumulative administration of sufentanil during the first 48 h after surgery.<h4>Results</h4>110 participants (55 in each group) were incBMC anesthesiology421https://www.ebi.ac.uk/biostudies/studies/S-EPMC11580488biostudies-literatureThe effect of pericapsular nerve group (PENG) block on postoperative analgesia in elderly patients who underwent proximal femoral nail anti-rotation surgery: a prospective, randomized-controlled trial.PMC11580488Wu XDYang RZChen YWu HChen TQiu LCfalseThe effect of pericapsular nerve group (PENG) block on postoperative analgesia in elderly patients who underwent proximal femoral nail anti-rotation surgery: a prospective, randomized-controlled trial.<h4>Background</h4>As a fascial plane block technique, further exploration is needed to determine the safety and efficacy of a peri-capsular nerve group (PENG) block in elderly patients with intertrochanteric femur fractures.
