*
VAS pain score at intraoperative and postoperative: T1: skin incision, T2: division of subcutaneous tissue, T3: PDC insertion, T4: catheter exit, T5: incision closing, T6: at rest at 2 hours postoperatively, T7: at rest at 24 hours postoperatively.
†
Rescue anesthesia: Those marked with * are ropivacaine (mL), and others are sufentanil (μg).
