【摘要】 目的观察针刺麻醉的镇痛效能。方法69例直肠癌手术患者随机分为Ⅰ组、Ⅱ组和Ⅲ组各23例。针刺麻醉取穴均为足三里、三阴交。Ⅰ组针刺诱导后全麻,Ⅱ组全麻后针刺,Ⅲ组单纯全麻。记录术中最低肺泡内有效浓度(MAC)。结果Ⅰ组MAC平均为(1.35±0.19)Vol%,Ⅱ组为(1.49±0.22)Vol%,Ⅲ组为(1.64±0.27)Vol%,全麻诱导前或全麻诱导后针刺均有降低全麻下行直肠癌手术患者所需MAC约0.29%、0.15%。3组相比较差异有非常显著性或显著性意义(P<0.01或P<0.05)。结论针刺麻醉具有一定的麻醉镇痛辅助作用,且以全麻前加强针刺诱导效能较佳。更多还原

【Abstract】 Objective To observe analgesic effect of acupuncture anesthesia. Methods Sixty-nine cases undergoing rectal cancer surgery were randomly divided into 3 groups, group Ⅰ, Ⅱ and Ⅱ, 23 cases in each group. Both Zusanli (ST 36) and Sanyinjiao (SP 6) were selected for acupuncture anesthesia. Group Ⅰ received general anesthesia after acupuncture induction, group Ⅱ received acupuncture after general anesthesia, and group Ⅲ received only general anesthesia. Minimum alveolar concentration (MAC) before and after operation was recorded. Results MAC was (1.35±0.19) vol% in the group Ⅰ, (1.49±0.22) vol% in the group Ⅱ and (1.64±0.27) vol% in the group Ⅲ. Acupuncture before and after general anesthesia could decrease respectively by about 0.29% and 0.15% of MAC in rectal cancer surgery undergoing general anesthesia, with a very significant difference (P<0.01) or a significant difference (P<0.05) among the 3 groups. Conclusion Acupuncture anesthesia has a certain adjuvant action for anesthesia and analgesia, and acupuncture before general anesthesia has a better action.更多还原
