摘要
目的 通过临床观察及理论探讨 ,否定硬膜外阻滞药液中加用肾上腺素的必要性。方法 选择涉及骶丛的硬膜外阻滞患者 6 0例 ,随机分为加肾素组及去肾素组 ,观察注药后中毒反应情况和止痛持续时间。结果 两组在中毒反应发生率和止痛持续时间方面没有明显区别 (P >0 .0 5 )。理论认为 :①肾上腺素对不同组织器官血管收缩有高度的选择性 ;②其缩血管效应有赖于用药高浓度下发生 ,表现短暂 ;③其体循环和微循环变化有利于血管外液体回流入血 ;④中毒反应的生化学基础与肾上腺有关 ;⑤增加应激反应的病理反应。结论 硬膜外阻滞药液中以不加肾上腺素为好。
After cli n ic observation and theoretical investiga tion,deny the neccesity of applying adrenaline(Ad ) to medicine of epidural block. Meth ods 60 cases of acaralesincluded epidural bl ock were randomly divided into Ad group and non-Ad group,observed the toxic reac tions and the analgestic time after inje ction. Results There was no sign ificant difference between two groups on the tox ic reaction rates and the analgestic tim e (P>0.05).Theoretical vlews:(1)vessel c on traction of Ad is high-chosen to differe nt histo-organs.(2)vessel contraction is depended on high concentration,and is sh ort.(3)change of general circulation and microcirculation is beneficial to inter histoliquid backinflux.(4)biochemical ba se of toxic reactions is concerned with Ad.(5)increase the stress reactions. Conclus ions That don’t apply Ad to medicine of epidural block would be better.
