Abstract
Purpose
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.
Methods
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.
Results
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.
Conclusion
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.
