Effect of Dezocine Combined With Sufentanil on the Quality of Postoperative Recovery and Analgesic Effect in Patients Undergoing Thoracic Surgery

Phase 4

Recruiting

• Conditions: Postoperative Pain; Rehabilitation
• Interventions: Drug: Dezocine

• Registration Number: NCT06439368
• Lead Sponsor: Yangtze River Pharmaceutical Group Co., Ltd.

Brief Summary

The goal of this clinical trial is to evaluate the effect of dezocine combined with sufentanil on postoperative recovery quality and analgesic effect in patients undergoing thoracic surgery. It will also learn about the safety of dezocine. Researchers will compare drug dezocine to Sufentanil to see if dezocine works to Improve postoperative pain and recovery quality for patients. Participants will undergo elective surgery and receive PCIA postoperatively，taking dezocine combine with sufentanil,or only sufentanil respectively. Visit the VAS score after connecting the analgesic pump 24h and 48h，and evaluate the Quality of Recovery

-15 score.

Inclusion Criteria

1. Patients undergoing elective thoracoscopic surgery under general anesthesia, and patients with moderate to severe pain requiring opioids or opioid-non-opioids combined analgesia after surgery as assessed by the investigator;
2. 18 to 65 years of age, male or female;
3. Body mass index (BMI) between 18-30 kg/m ² (BMI = body weight (kg)/height ² (m ²)), including borderline values;

Exclusion Criteria

1. Inability to understand the nature, significance, possible benefits, possible inconveniences and potential risks of the trial, or inability to understand the study procedures and pain-related assessment methods;
2. Patients who cannot accept the postoperative analgesia specified in the protocol;
3. Clinician judgment: liver and kidney dysfunction has clinical significance (ALT and AST > 2 times the upper limit of normal; BUN and/or Urea > 2 times the upper limit of normal, Cr > 2 times the upper limit of normal; dialysis treatment within 28 days before surgery), or coagulation dysfunction has clinical significance (PT or APTT or TT > the upper limit of normal), or poor blood pressure control (sitting SBP > 160 mmHg or SBP < 90 mmHg), or oxygen saturation (without oxygen) < 94%;
4. Patients with high risk of respiratory depression or respiratory depression (such as sleep apnea syndrome);
5. Patients who are allergic to the test drugs (dezocine, sufentanil);
6. History of bronchial asthma;
7. Patients with hypothyroidism;
8. Patients with uncontrolled gastrointestinal ulcers, gastrointestinal bleeding or perforation before surgery; or patients with paralytic ileus;

Arm && Interventions

Group	Intervention	Description
Test group	Dezocine	At the end of the operation, dezocine 1.0 mg/kg + sufentanil 2.0 ug/kg (prepared as 200 ml, background volume 2 ml/h, single dose 2 ml/time, locking time 15 min) was uniformly administered by PCIA; 3 ml test dose was administered immediately after the analgesic pump was connected at the end of the operation, and continuous analgesia was performed for 48 hours after the operation.
Control group	Dezocine	At the end of the operation, sufentanil injection 3.0 ug/kg (prepared as 200 ml, background volume 2 ml/h, single dose 2 ml/time, locking time 15 min) was uniformly administered by PCIA; 3 ml test dose was immediately administered after the analgesic pump was connected at the end of the operation, and continuous analgesia was performed for 48 hours after the operation.
