Notes: MAP: Mean arterial pressure; HR: Heart rate; SA-AQLB: anterior quadratus lumborum block at the lateral supra-arcuate ligament; SC-QLB: subcostal anterior quadratus lumborum block; SA group: ultrasound-guided anterior quadratus lumborum block at the lateral supra-arcuate ligament group; SC group: ultrasound-guided subcostal anterior quadratus lumborum block group; GA group: general anesthesia-only group.
