After general anesthesia induction, unilateral QLB was performed under ultrasound guidance in the Q group. The amount of opioid use via patient-controlled analgesia (PCA) and the resting and movement pain visual analog scale (VAS) scores when the patient left the postanesthesia care unit (PACU) and 4, 8, 12, and 24 hours after surgery were recorded. Postoperative complications were recorded for both groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>At 24 hours post-surgery, opioid consumption amounts via PCA (48.4 [48.1\u201348.6]\u2009mL) in the Q group were significantly lower compared with the C group (52.0 [51.0\u201353.8]\u2009mL).
