The primary outcomes were the effectiveness of postoperative pain control as assessed by the numeric pain rating scale (NRS) and the incidence of side effects. Secondary outcomes included hemodynamic parameters (systolic and diastolic blood pressure, heart rate), motor block assessment, sensory block duration, analgesia duration, and the need for additional analgesia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Both groups achieved similar pain control as indicated by NRS scores.
