Randomized trial demonstrates anesthetic efficacy of quadratus lumborum block in inguinal herniorrhaphy, suggesting improved postoperative pain control.

Key Points

This research aims to compare the anesthetic efficacy of quadratus lumborum block and local infiltration anesthesia during inguinal herniorrhaphy.
70 patients undergoing elective inguinal herniorrhaphy were randomly assigned to receive either QLB or LIA.
Primary outcome measured was the area under the curve of pain numeric rating scale during surgery.
Secondary outcomes included anesthesia efficacy, additional local anesthetic consumption, intraoperative traction reaction, and postoperative pain scores.
QLB showed a higher AUC for intraoperative NRS scores compared to LIA (15.7 vs 13.1, P=0.002).
QLB required a greater volume of rescue local anesthetics (11.0 mL vs 5.7 mL, P=0.02).
QLB had lower scores for visceral traction reaction and better resting NRS pain scores at 12 h postoperatively.
