Femoral nerve blocks have been shown to improve\n postoperative analgesia at the expense of quadriceps weakness. The\n pericapsular nerve group (PENG) block could be an alternative that may\n improve postoperative analgesia while preserving quadriceps strength.\n Our hypothesis was that a PENG block would provide superior\n postoperative analgesia compared with a sham block following\n arthroscopic hip surgery.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Subjects presenting for arthroscopic hip surgery were randomized in\n a 1:1 ratio to either an ultrasound-guided unilateral, single-injection\n PENG block (PENG group) with 20 mL of 0.5% ropivacaine or a sham\n injection with 5 mL of 0.9% normal saline (Sham group) prior to\n receiving general anesthesia. The primary outcome of this study was\n worst pain score within 30\u2009min of emergence from anesthesia. Secondary\n outcomes included opioid consumption, patient satisfaction with\n analgesia, opioid-related adverse events, and persistent opioid use at 1\n week.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Sixty-eight subjects, 34 from the PENG group and 34 from the Sham\n group, completed the study per protocol. Analysis of the primary outcome\n demonstrated a mean difference in pain scores of \u22120.79 (95% CI \u22121.96 to\n 0.37; p=0.17) between the PENG and Sham groups immediately following\n surgery. No secondary outcomes showed statistically significant\n differences between groups.<\/jats:p>\n <\/jats:sec>\n \n Discussion<\/jats:title>\n This study demonstrates that a preoperative PENG block does not\n improve analgesia following arthroscopic hip surgery.<\/jats:p>\n <\/jats:sec>\n \n Trial reigstration number<\/jats:title>\n NCT04508504<\/jats:ext-link><\/jats:p>\n
