A Study on the Efficacy and Safety of Anrikefon for Postoperative Pain Relief Following Laparoscopic Cholecystectomy

2026년 7월 28일 업데이트: Affiliated Hospital of Guangdong Medical University

A Multicenter, Randomized, Parallel-Group Controlled Study Evaluating the Efficacy and Safety of Anrikefon in Postoperative Pain Management in Patients Undergoing Elective Laparoscopic Cholecystectomy Under General Anesthesia

This study is a multicenter, randomized, 1:1 parallel-group controlled clinical trial designed to evaluate the efficacy and safety of Anrikefon for postoperative analgesia in patients undergoing elective laparoscopic cholecystectomy (LC) under general anesthesia. Enrolled patients were randomly assigned to two groups (the Anrikefon group and the dizocine group) and received regular intravenous administration of the respective medication following the corresponding surgical procedure. The primary efficacy endpoint was the Quality of Recovery (QoR-15 score) at 24 hours postoperatively, combined with the Numerical Rating Scale (NRS), the Brief Pain Inventory (BPI), sleep quality (RCSQ), and postoperative recovery progress (time to first meal, first flatus, and first ambulation, etc.) for a comprehensive evaluation of efficacy; At the same time, safety indicators-including adverse events (such as nausea and vomiting, and shoulder and back pain), vital signs, and laboratory test results-were systematically monitored during the follow-up period to comprehensively evaluate the clinical utility of this protocol.

주요 결과 측정

결과 측정
측정값 설명
기간
Quality of Recovery-15 (QoR-15) scale at 24 hours postoperatively.
기간: 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.
24 hours after surgery

2차 결과 측정

결과 측정
측정값 설명
기간
Resting and movement pain Numeric Rating Scale (NRS) Area Under the Curve (AUC 0-24h) after the initial dose
기간: 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).
24 hours after surgery
Resting and movement (turning over) postoperative pain scores using the Numeric Rating Scale (NRS) at 0h, 2h, 8h, 16h, and 24h postoperatively.
기간: 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.
기간: 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.
기간: 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.
기간: 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).
기간: 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
기간: 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).
기간: 2 weeks post-surgery
Follow-up records document the occurrence and severity of adverse events in patients.
2 weeks post-surgery
12-Lead Electrocardiogram
기간: 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
기간: 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
기간: 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.
