硬膜外麻醉时,局麻药仅有部分达到脊神经和脊神经根靶神经纤维,并且主 要是作用于椎间孔处由鞘膜管包裹的神经根,少部分通过硬脊膜直接作用于脊髓, 继而发生一系列循环动力学改变。单次硬膜外麻醉是将局麻药一次注入硬膜外隙 进行麻醉的方法,因一次用药剂量偏大,常引起血压剧烈变化,并在注药过程中 可能刺破硬脊膜,使大量局麻药进入蛛网膜下隙出现全脊椎麻醉等意外。所以,

2%利多卡因持续硬膜外麻醉在妇科 手术应用剂量探讨
目 的
探讨2%利多卡因持续硬膜外麻醉不同剂量对妇科手术患者的影响。
方法
随机选择A S A I.Il级择期行妇科手术的病人27例,年龄25.55岁。按随 机区组设计将27例患者按身高分为3个区组(I:155cm.160era、II:161em.165era、 III:166.170cm),每区组9例,每个区组内采用随机数字法将将其分为三组(A、B、 C),各3例,随机接受三种2%利多卡因注药速度(5ml/h,8ml/h,10ral/h)。病人入 室每5分钟测定并记录(1)心率、平均动脉压、血氧饱和度、心电图。 (2)注
