Objective To investigate the efficacy and safety of different doses of dezocine at different administration time on analgesia after laparoscopic cholecystectomy.Methods 80 patients elected from ASA Ⅰ-Ⅱ grade laparoscopic cholecystectomy were randomly divided into four groups,20 cases in each group.Group Ⅰ was anesthetized by intravenously injected dezocine 0.10mg/kg before the surgery,group Ⅱ was anesthetized by dezocine 0.15mg/kg before the surgery,group Ⅲ was anesthetized by intravenously injected dezocine 0.10mg/kg after stopping anesthetic surgery,and group Ⅳ was anesthetized by intravenously injected dezocine 0.15mg/kg after stopping anesthetic surgery.The postoperative pain scores were observed 1,6,12,24 hours after operation in the four groups by using visual analog scale (VAS),comfort score (BCS),and anesthesia recovery score (modified Aldrete score).Results TheVAS of the four groups 1 hour after surgery:group Ⅰ and group Ⅲ was significantly different(t =2.308,P =0.036),group Ⅰ and group Ⅳ was significantly different (t =2.106,P =0.042),group Ⅱ and group Ⅲ was significantly different (t =2.711,P =0.014),group Ⅱ and group Ⅳ was significantly different (t =2.317,P =0.037).The BCS 1 hour after surgery:group Ⅰ and group Ⅲ was significantly different(t =2.108,P =0.042),group Ⅰ and group Ⅳ was significantly different(t =2.069,P =0.048),group Ⅱ and group Ⅲ was significantly different (t =2.353,P =0.033),group Ⅱ and group Ⅳ was significantly different (t =2.361,P =0.036).The VAS 6 hours after surgery:group Ⅰ and group Ⅲ was significantly different (t =2.084,P =0.045),group Ⅱ and group Ⅲ was significantly different(t =2.309,P =0.038),group Ⅱ and group Ⅳ was significantly different(t =2.303,P =0.040).The BCS 6 hours after surgery:group Ⅰ and group Ⅲ was significantly different (t =2.294,P =0.041),group Ⅱ and group Ⅲ was significantly different(t =2.322,P =0.035),group Ⅱ and group Ⅳ was significantly different (t =2.070,P =0.048).The BCS 12 hours after surgery:group Ⅱ and group Ⅲ was significantly different(t =2.518,P =0.047).VAS and BCS scores at other time points had no significant difference (P ＞ 0.05).Conclusion The analgesic after laparoscopic gallbladder surgery using dezocine 0.10mg/kg-0.15mg/kg,especially 0.15mg/kg administered anesthesia before surgery,can effectively relieve postoperative pain and improve postoperative comfort,reduce postoperative analgesic(pain pump) and has less adverse reactions,which is worthy of promotion.

Abstract OBJECTIVE To determine the index weight, optimize the extraction process of gastropathy oral thick paste 1. METHODS Taking the amount of water added, extraction time and extraction times as factors, depend on the single factor experiment, L9(34) orthogonal table was selected to design the experiment. The content of chlorogenic acid was determined by HPLC and the content of total flavonoids content was determined by ultraviolet spectrophotometry. With the above two contents plus the yield of dry extractum as the evaluation index, the weights were assigned based on the analytic hierarchy process, entropy weight method and independence weight method, and the extraction process was optimized by orthogonal experimental design. RESULTS Multi-index scoring was more scientific and reasonable, and the final optimal extraction conditions for gastropathy oral thick paste 1 were as follows: add 8 times the amount of water, extract twice and 0.5 h for each time. CONCLUSION The optimized extraction process using analytic hierarchy process, entropy weight method and independence weight method is reasonable, feasible, stable, and reproducible, which is suitable for the preparation of gastropathy oral thick paste 1, providing reference for subsequent research and development.
