Quadratus lumborum block in laparoscopic inguinal hernia repair: A single center study.

Objective: To evaluate the efficacy of QL block in patients undergoing laparoscopic TEP inguinal hernia repair. Study Design: Randomized Clinical Trial. Setting: Kalsoom International Hospital, Islamabad. Period: Dec 2022 to June 2023. Methods: In this, all patients between the ages of 18 and 70 who were scheduled for laparoscopic TEP inguinal hernia repair to repair a one-sided inguinal hernia and did not have any complications related to the hernia. In one group, the patients received general anesthesia and in the other group, the patients were given sedation along with a technique called QL block. Age, gender, pain score on VAS at 1 hours, 6 hour and 12 hours after procedure was noted. Comparison of pain according to the VAS by type of anesthesia was done between the two groups and independent sample t-test was applied to see the statistical significant. Results: The patients' mean age was 43 + 9.09 years. Around 70% of the patients were males, while 30% were females, indicating a male predominance. The study's outcome was the mean pain score after 1 hour, 6 hours, and 12 hours. The two techniques of anesthesia utilized in the two groups were compared in terms of pain. The mean VAS at 1 hour after the initiation of anesthesia was not significantly different between the two groups, but it was statistically significant at 6 and 12 hours (p value of 0.001). Conclusion: QL block is a safe and effective alternative for patients undergoing TEP inguinal repair because to the observed reduction in early postoperative pain, shorter hospitalization, and cheaper anesthetic and hospital costs. Although our research showed that pain was significantly reduced for up to 12 hours after the operation, more information is needed before we can confidently endorse it for widespread use.
