摘　　要：目的：比较不同年龄组对不同浓度的盐酸罗哌卡因臂丛神经感觉、运动神经阻滞起效和维持时间的影响。方法：选择在臂丛神经阻滞下行上肢外科手术的患者80例，根据年龄分为青年组（18—40岁）和老年组（65—80岁）。两组再随机分为为两组，分别给予相同容量、浓度为0．375％和0．5％的盐酸罗哌卡因。记录感觉、运动神经阻滞起效和维持时间。结果：感觉、运动神经阻滞起效时间老年组较青年组显著缩短（P〈0．05）。感觉、运动神经阻滞维持时间老年组较青年组明显延长（P〈0．05）。0．5％的盐酸罗哌卡因感觉、运动神经阻滞起效时间较0．375％浓度有缩短趋势，但差异无统计学意义（P〉0．05），维持阻滞时间稍延长，差异电无统计学意义（P〉0．05）。结论：年龄增长可增加臂丛神经感觉、运动神经阻滞的效果，相同容量的0．375％和0．5％的盐酸罗哌卡因阻滞差异无统计学意义（P〉0．05）。Objective To compare effectacting and maintair, time of ropivaeaine hydrochloride in different concentrations in brachial plexus sensation and motion block in patients of different ages. Method Eighty patients who were scheduled for selective upper limb surgery with brachial plexus block were divided into group Young （ with the age from 18 to 40） and group Old （with the age from 65 to 80）. The two groups were divided randomly into two groups separately in which ropivaeaine hydrochloride was administrated with same volmne but different concentrations （0. 375% and 0. 5% ）. Effect - acting time of sensation and motion block and maintain time were recorded. Results The acting time of sensation and motion block was significantly shorter（ P 〈 0. 05 ） and the maintain time was notably longer（ P 〈 0. 05） in elder patients than that in young patients. Although there seemed to be a tendency that ropivacaine hydrochloride with 0. 5% concentration acted more quickly and maintained longer than 0. 375% ,there was no statistical significance. Conclusion Effect of brachial plexus sensation and motion block improves with patients＇ age. Same volumes of ropivacaine hydrochloride with concentration of 0. 375% and 0. 5% make no difference in their efficiency.
