Objective To observe the effects of intravenous injection of fentanyl and tramadol on postoperative analgesia in laparoscopic cholecystectomy of clinical efficacy.Methods 80 cases treated with laparoscopic cholecystectomy were randomly divided into the fentanyl group (group F) and tramadol group (group Q).VAS score,adverse reaction incidence and patient satisfaction,were observed after the administration of 0.5,1,2,4,8,12h.Results In group F after administration of 0.5,1,2h,VAS score was better than that of group Q; group F after administration of the drug 4,8 h VAS score was inferior to group Q;two groups of patients in postoperative 12h VAS scores showed no significant difference in group F;the overall incidence of adverse reactions was higher than that of group Q,patients' satisfaction was higher than that of group Q.Conclusion Intravenous fentanyl in laparoscopic cholecystectomy operation postoperative overall are superior to the analgesic effect of tramadol,with high patient's satisfaction.
