Abstract： 目的:经胆道镜行Oddi括约肌测压,观察常规剂量吗啡对Oddi括约肌的作用,以及常规剂量的山莨菪碱、阿托品与解痉灵对吗啡的拮抗作用.方法:胆道术后留有T管的患者共40例,随机分为山莨菪碱组、阿托品组、解痉灵组、对照组.测定用药前后的十二指肠压(DP)、Oddi括约肌基础压(SOBP)、收缩波幅(SOCA)、收缩频率(SOF)、收缩间期(SOD)及胆总管压(CBDP).结果:肌注吗啡后Oddi括约肌基础压、收缩波幅、收缩频率及胆总管压均明显增高,肌注15 mg山莨菪碱、0.75 mg阿托品后,Oddi括约肌收缩幅度,基础压明显降低,肌注20 mg解痉灵后Oddi括约肌收缩波幅,Oddi括约肌基础压及收缩频率明显下降.但是解痉灵组,阿托品组,山莨菪碱组各组数据无差别.结论:常规剂量的吗啡可引起十二指肠压、Oddi括约肌收缩波幅、Oddi括约肌基础压、胆总管压增加,山莨菪碱、阿托品、解痉灵可以拮抗吗啡对Oddi括约肌的激动作用.
