结局指标
主要结局
Total fentanyl consumption within 72 hours postoperatively.
时间窗: Total fentanyl consumption within 72 hours postoperatively.
The total amount of fentanyl administered to the patient via IV PCA during the initial 72-hour postoperative period will be recorded and compared among groups to assess analgesic efficacy.
次要结局
- Pain intensity scores (NRS) at rest and during movement.(Pain intensity: Measured at 24, 48, and 72 hours postoperatively.)
- Time to first flatus and bowel movement.(Bowel function: Time to first flatus and bowel movement recorded until discahrge (within 6 days))
- Occurrence of postoperative nausea and vomiting (PONV).(PONV: Assessed daily for 72 hours.)
- Wound healing assessment, including seroma and infection rates.(Wound healing: Evaluated at regular intervals until first outpatient day (within 14 days))
- Length of hospital stay.(Hospital stay: up to 1 month)
- Quality of recovery (QoR-15).(QoR-15: Measured at baseline and 72 hours postoperatively.)
