They received patient-controlled intravenous analgesia (PCIA) after the operation with either dezocine 0.8 mg/kg (Group D) or sufentanil 2 μg/kg (Group S). Both groups also received ondansetron 8 mg diluted to 100 mL with saline. The primary outcome was the Th1/Th2 cytokines ratio at predetermined intervals, 30 min before the induction of general anaesthesia and 0, 12, 24 and 48 h after surgery. The secondary endpoints were patients’ pain scores, measured on a visual analogue scale (VAS) at predetermined intervals (0, 12, 24 and 48 h after surgery), and side effects at follow-up 48 h after surgery.Results: The Th1/Th2 cytokines ratio in Group D was significantly higher than Group S (P< 0.05) 12, 24 and 48 h after the operation. There were no significant differences in VAS pain scores between groups at 0, 12, 24 and 48 h after surgery (P> 0.05). Compared to Group S, the incidence of postoperative nausea, vomiting and lethargy was significantly lower in Group D (P< 0.05).Conclusion: Dezocine increases the ratio of Th1/Th2 cytokines, relieves postoperative pain and causes fewer side effects in patients undergoing laparoscopic radical gastrectomy.Keywords: dezocine, gastric cancer, laparoscopic radical operation, postoperative analgesia, Th1/Th2 cytokines
