Group R underwent ultrasound-guided RISS block with 0.25% ropivacaine hydrochloride 0.5\u00a0ml\/kg immediately after surgery. Group C was given standard general anaesthesia, and patient-controlled intravenous analgesia (PCIA) was used in the postoperative period in both groups. The visual analogue scores (VAS) at rest and during movement at 2\u00a0hours(h), 24\u00a0h, and 48\u00a0h postoperatively were used as the primary outcome measures. Secondary outcomes included postoperative consumption of sufentanil; preoperative and postoperative left and right-sided DE during calm and deep breathing, and the occurrence of adverse effects such as postoperative nausea and vomiting (PONV), dizziness, somnolence, puncture site infection, and hematoma.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      At 2\u00a0h, 24\u00a0h, and 48\u00a0h postoperatively, patients in Group R had lower VAS scores at rest (median [Q1, Q3]: 1.00 [1.00, 1.00]; 1.00 [1.00, 1.00]; 0.00 [0.00, 1.00]) and during movement (2.00 [2.00, 3.00]; 2.00 [2.00, 2.00]; 2.00 [1.00, 2.00]) than those in Group C (resting: 2.00 [2.00, 2.00]; 2.00 [2.00, 2.00]; 1.00 [1.00, 2.00]; movement: 3.00 [3.00, 4.00]; 3.00 [3.00, 4.00]; 3.00 [2.00, 4.00]) (all\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.0001).
