About this study
Official title: Effect of Oliceridine-based Intravenous Patient-Controlled Analgesia on Chronic Postsurgical Pain After Video-Assisted Thoracoscopic Lung Resection: A Multicenter Randomized Double-Blind Controlled Trial Protocol
The primary objective is to evaluate the impact of oliceridine versus sufentanil for perioperative analgesia on the incidence of chronic postsurgical pain (CPSP) with functional impact in patients undergoing video-assisted thoracoscopic surgery.
Read the detailed description
The primary objective is to evaluate the impact of oliceridine versus sufentanil administered via patient controlled intravenous analgesia (PCIA) for perioperative analgesia on the incidence of chronic postsurgical pain (CPSP) with functional impact in patients undergoing video-assisted thoracoscopic surgery. This is a multicentre, randomised, double-blind, controlled trial enrolling 320 patients across seven Chinese tertiary centres.

| Study group | Role | What they receive |

| Oliceridine group | Experimental | Administer a loading dose of 0.02 mg/kg intravenously 20-30 minutes before the end of surgery. Postoperative PCA pump configuration: 0.4 mg/kg oliceridine diluted with normal saline to a total volume of 100 mL, with a background infusion rate of 2 mL/h, PCA bolus dose of 0.5 mL per injection, lockout interval of 15 minutes, and treatment duration of 48 hours. The cumulative oliceridine dose should not exceed 27 mg per 24 hours, in accordance with the FDA prescribing information. Receives: Drug: Oliceridine |
| Sufentanil group | Active comparator | Administer a loading dose of 0.1 μg/kg intravenously 20-30 minutes before the end of surgery. Postoperative PCA pump configuration: 2 μg/kg sufentanil diluted with normal saline to a total volume of 100 mL, with a background infusion rate of 2 mL/h, PCA bolus dose of 0.5 mL per injection, lockout interval of 15 minutes, and treatment duration of 48 hours. Receives: Drug: Sufentanil |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of chronic postsurgical pain with functional impact at 3 months after surgery
CPSP is a composite binary endpoint, positive only when all three criteria are met: (1) pain related to thoracoscopic surgery, confirmed by the scripted question "Do you currently have persisting pain related to your thoracoscopic surgery?", localized to the surgical site or a referred area, present for at least 3 months, and not attributable to other causes (local infection, tumour recurrence, or a new surgical or medical condition); (2) average numeric rating scale (NRS) pain score >= 1 (0-10) at the surgical site during the week preceding the assessment; and (3) pain-related functional interference, defined as a pain interference score >= 1 on the Brief Pain Inventory-Short Form (validated Chinese version), calculated as the mean of 7 interference items (each 0-10; prorated mean if at least 4 of 7 items are completed), with a 1-week recall period.
Measured: At 3 months after surgery (assessment window: postoperative day 90 +/- 14 days)
Secondary outcomes (11)
Postoperative acute pain NRS score
Acute pain intensity at 24 and 48 hours after surgery, measured by the Numeric Rating Scale (NRS), which ranges from 0 (no pain) to 10 (worst pain imaginable). Higher scores indicate worse outcomes (greater pain intensity).
Measured: 24h and 48h after surgery
Quality of Recovery-15 (QoR-15) score
The QoR-15 assesses postoperative recovery quality across 15 items (0-10 each; total 0-150), administered at the bedside. Higher scores indicate better recovery.
Measured: 24h and 48h after surgery
Cumulative PCA opioid consumption and bolus deliveries
Total delivered volume of the study solution (mL) and number of bolus deliveries (attempted and successful) recorded by the PCA pump during the 48-hour intervention period. Delivered oliceridine and sufentanil doses will be derived from body weight-based concentrations. The cumulative 24-hour oliceridine dose will be documented against the 27 mg/day threshold specified in the prescribing information.
Measured: 0-48 hours postoperatively
Incidence of opioid-related adverse events
Incidence of opioid-related adverse events (ORAEs) within 48 hours postoperatively, including: postoperative nausea and vomiting (PONV), respiratory depression (SpO₂ <92% or respiratory rate <8/min), pruritus, sedation (Ramsay Sedation Scale ≥4), and dizziness.
Measured: 0-48 h postoperatively
Use and frequency of rescue analgesic administration
Dose and frequency of rescue analgesics
Measured: 0-48h postoperatively, 1 month postoperatively, 3 months postoperatively
Brief Pain Inventory-Short Form (BPI-SF) pain severity and pain interference scores
BPI-SF pain severity (mean of 4 items) and pain interference (mean of 7 items) scores, each 0-10, administered by face-to-face interview or structured telephone interview with a 1-week recall period.
Measured: 1 month postoperatively, 3 months postoperatively
Incidence of neuropathic pain component (DN4i ≥ 4)
The 7-item interview version of the Douleur Neuropathique 4 questionnaire (DN4i, score range 0-7) administered by structured telephone interview. DN4i >= 4 indicates the presence of neuropathic pain components.
Measured: 1 month postoperatively, 3 months postoperatively
Sleep quality assessment
Sleep quality assessed by the Pittsburgh Sleep Quality Index (PSQI), a 19-item self-rated questionnaire yielding a global score ranging from 0 to 21. Higher scores indicate worse outcomes (poorer sleep quality).
Measured: 1 day preoperatively(baseline), 1 month postoperatively, 3 months postoperatively
Psychological status assessment
Anxiety and depressive symptoms assessed by the Hospital Anxiety and Depression Scale (HADS), a 14-item self-report questionnaire with two 7-item subscales: the HADS-Anxiety subscale and the HADS-Depression subscale, each ranging from 0 to 21. Higher scores indicate worse outcomes (greater anxiety or depressive symptoms).
Measured: 1 day preoperatively(baseline), 1 month postoperatively, 3 months postoperatively
Pain catastrophizing level
Pain catastrophizing assessed by the Pain Catastrophizing Scale (PCS), a 13-item self-report questionnaire with a total score ranging from 0 to 52. Higher scores indicate worse outcomes (higher levels of pain catastrophizing).
Measured: 1 day preoperatively(baseline), 1 month postoperatively, 3 months postoperatively
Quality of life assessment
Quality of life assessed by the 36-Item Short Form Health Survey (SF-36), which yields 8 domain scores, each transformed to a scale of 0 to 100. Higher scores indicate better outcomes (better health-related quality of life).
Measured: 1 day preoperatively(baseline), 3 months postoperatively

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
Contact Yang Jiao, Doctor (+86 159 0029 2506, jiaoxiuxiu1987@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of chronic postsurgical pain with functional impact at 3 months after surgery (time frame: At 3 months after surgery (assessment window: postoperative day 90 +/- 14 days)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
