Effect of Dezocine Combined With Sufentanil on the Quality of Postoperative Recovery and Analgesic Effect in Patients Undergoing Thoracic Surgery: a Randomized, Double-blind, Parallel-controlled, Multicenter Clinical Study
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.
