II II Abstract Objective: To evaluate the preventive effects of dezocine and parecoxibprevent postoperative pain in patients after reminfentanil-based anesthesia. Methods: Ninety ASA Ⅰ or Ⅱ patients，aged 45-55，weighing 45-65 kg，undergoing laparoscopic hysterectomy，were randomly divided into 3 groups(n=30 each): fentanyl group(group A), dezocine group(group B) and parecoxib group(group C). Anesthesia was induced with midazolam,propofol,remifentanil and cisatracurium. The patients were mechanically ventilated after tracheal intubation. Anesthesia was maintained with target-controlled infusion of remifentanil (target effect-site concentration 4μg/L),intravenous infusion of propofol 4-6 mg·kg-1·h-1 and atracurium0.5mg·kg-1·h-1. Group B received intravenous injection of dezocine 0.2 mg/kg, group C received intravenous injection of parecoxib 40 mg at 20 min before the end of surgery，group A received intravenous injection of fentanyl 1μg/kg at 10 min before the end of surgery. The recovery time and extubation time were recorded. Visual analog scale(VAS), Bruggrmann comfort scale(BCS) and sedation and agitation scale(SAS) at immediately,1 h after recovery from anesthesia(T0，1),and the incidence of nausea and vomiting and shivering and dysphoria after extubation were recorded. Result: Compared with group A,VAS score was decreased and BCS score was increased and SAS score was decreased at T0-1 in group B, VAS score was increased and BCS score was decreased and SAS score was increased at T0-1 in group C(P＜0.05). Compared with group A, the incidence of nausea and vomiting was increased in group B, shivering and dysphoria was increased in group C(P＜0.05). Conclusion: Intravenous injection of dezocine 0.2 mg/kg at 20 min before the end of surgery can reduce postoperative pain with little side effects in patients after reminfentanil-based anesthesia.
