%X <B>OBJECTIVE: </B>There is limited research on the impact of an ilioinguinal-iliohypogastric nerve block on intraoperative opioid consumption when conducting groin hernia repair in adults. Thus, the aim was to evaluate ilioinguinal-iliohypogastric nerve block for groin hernia patients at Shouldice Hospital.<BR><B>METHODS: </B>The study was a pilot retrospective chart review on patients who underwent a Shouldice Repair from November 2023 to December 2023. This study compared individuals receiving an ilioinguinal-iliohypogastric nerve block with local anesthesia and fentanyl analgesia to those who received local anesthesia and fentanyl analgesia, by manually matching 1:1 on 12 demographic and intraoperative characteristics. Comparison between groups was performed using chi-square/Fisher Exact test for categorical and t-test/Mann-Whitney test for numerical variables depending on data distribution. Multivariable regression analysis was used to examine predictors of intraoperative use of fentanyl.<BR><B>RESULTS: </B>In this study 50 matched pairs of unilateral primary inguinal hernia patients were analyzed. The ilioinguinal-iliohypogastric nerve block patients had lower recorded intraoperative fentanyl (85mcg less than control, p < .001) and dimenhydrinate (13 mg less than control, p < .001) than the control group patients. No differences were found in postoperative day 0 to 3 for acetaminophen, non-steroidal anti-inflammatory drug, and opioid consumption between the patients who did receive an ilioinguinal-iliohypogastric nerve block prior to surgery and those that did not.<BR><B>CONCLUSIONS: </B>The administration of an ilioinguinal-iliohypogastric nerve block prior to primary inguinal hernia repair using a Shouldice Repair is associated with a significantly lower intraoperative fentanyl consumption compared to non-administration.
