Abstract
Background and Aims:
Inguinal hernia surgeries can pose significant postoperative pain, leading to chronic pain syndromes when not managed well.
Material and Methods:
Sixty American Society of Anesthesiologists (ASA) I/II adult patients scheduled to undergo unilateral inguinal hernia surgeries were enrolled in this trial. The patients were randomly allocated into three groups according to the various approaches of ultrasound-guided quadratus lumborum (QL) block: group transmuscular (TM): TM or anterior approach, group L: lateral approach, and group P: posterior approach. All the patients underwent surgery under subarachnoid blockade. A QL block was administered at the end of the surgery.
Results:
A total of 19 patients in each group were analyzed. Patients in the TM group had the least 24-hour requirement of fentanyl (
Conclusion:
The TM approach of QL block is an effective analgesic strategy in patients undergoing unilateral hernia surgeries. It could form a part of the multimodal analgesic regimen for such patients.
