Quality of Recovery-15 (QoR-15) scale at 24 hours postoperatively.
Zeitfenster: 24 hours after surgery
|
The QoR-15 scale was used 24 hours after surgery to assess the quality of patients' postoperative recovery.
The total score of the QoR-15 scale ranges from 0 to 150, with higher scores indicating a better quality of postoperative recovery.

Resting and movement pain Numeric Rating Scale (NRS) Area Under the Curve (AUC 0-24h) after the initial dose
Zeitfenster: 24 hours after surgery
|
Pain intensity was assessed using the 11-point Numerical Rating Scale (NRS), ranging from 0 (no pain) to 10 (the most intense pain imaginable).
NRS scores were recorded at multiple time points between the first postoperative administration and 24 h ± 1 h, both while the subject was at rest and when turning over, to calculate the AUC 0-24 h.
A higher AUC value indicates more severe cumulative pain over 24 hours (a worse outcome).

|
Resting and movement (turning over) postoperative pain scores using the Numeric Rating Scale (NRS) at 0h, 2h, 8h, 16h, and 24h postoperatively.
Zeitfenster: 24 hours after surgery
|
Pain intensity was assessed using an 11-point Numerical Rating Scale (NRS), with scores ranging from 0 (no pain) to 10 (the most intense pain imaginable); higher scores indicate more severe pain (and a poorer prognosis).
Participants' NRS scores were recorded at the following time points: within 5 minutes of the first postoperative medication administration, both at rest and while turning over; 2 hours ± 15 minutes after the first postoperative medication administration; 8 hours (within 30 minutes before the second postoperative medication administration); 16 hours (within 30 minutes before the last postoperative medication administration); and 24 hours ± 1 hour.

24 hours after surgery

|
Rescue analgesic utilization: Cumulative consumption of rescue analgesia (meperidine 75 mg) at 0-12h and 0-24h after the first dose, number of rescue interventions, time to first rescue, and the percentage of subjects not requiring rescue analgesia.
Zeitfenster: 24 hours after surgery
|
Record the cumulative dose of rescue analgesics (pethidine 75 mg) administered 0-12 hours and 0-24 hours after the patient's first postoperative dose, as well as the time at which rescue analgesics were first administered.
|
24 hours after surgery
|
|
Incidence of shoulder discomfort, back pain, nausea, and vomiting in each group.
Zeitfenster: 24 hours after surgery
|
During the medical interview, ask the patient whether they have experienced shoulder discomfort, back pain, nausea, or vomiting.
|
24 hours after surgery
|
|
Time to first oral intake, time to first flatus/defecation, and time to first ambulation.
Zeitfenster: 24 hours after surgery
|
The medical record documents the patient's mealtimes, times of flatulence and bowel movements, and times of getting out of bed to move around.
|
24 hours after surgery
|
|
Sleep quality on postoperative day 1 assessed by the Richards-Campbell Sleep Questionnaire (RCSQ).
Zeitfenster: 24 hours after surgery
|
Every morning upon waking, participants immediately used the Richards-Campbell Sleep Questionnaire (RCSQ) to review and evaluate their sleep from the previous night.
The total RCSQ score is the average of its five items, with a scoring range from 0 (worst sleep) to 100 (best sleep); a higher score indicates better sleep quality (better outcome).

24 hours after surgery

|
Postoperative Brief Pain Inventory (BPI) Scores
Zeitfenster: 24 hours after surgery
|
Twenty-four hours after surgery, the Brief Pain Inventory (BPI) was used to assess participants' pain intensity and the extent to which pain interfered with their daily activities over the past 24 hours.
The scale ranges from 0 to 10 points (0 indicates no pain/no interference, and 10 indicates the most intense pain imaginable/complete interference).
A higher score indicates more severe pain and a greater impact on daily life (i.e., a worse outcome).
|
24 hours after surgery
|
|
Incidence and severity of adverse events (AEs).
Zeitfenster: 2 weeks post-surgery
|
Follow-up records document the occurrence and severity of adverse events in patients.
|
2 weeks post-surgery
|
|
12-Lead Electrocardiogram
Zeitfenster: Baseline and the 24 hours After Surgery
|
During the trial, 12-lead ECG examinations were performed at regular intervals to record the ECG diagnosis (normal/abnormal), ECG heart rate (beats per minute), and QT/Qtc/PR (ms).
|
Baseline and the 24 hours After Surgery
|
|
Cumulative use of antiemetics within 0-24 hours after the first postoperative dose in each group
Zeitfenster: 24 hours after surgery
|
Record and compare the total cumulative dose of antiemetic medications prescribed and administered to patients in each group within the first 24 hours after the initial postoperative dose.
|
24 hours after surgery
|
|
Proportion of patients in each group who received antiemetics within 0-24 hours after the first postoperative dose
Zeitfenster: 24 hours after surgery
|
Calculate and compare the percentage of patients in each group who required at least one dose of rescue antiemetic medication within the first 24 hours after the initial postoperative administration.
