摘要
目的探讨不同浓度和容量的罗哌卡因应用于腰丛坐骨神经联合阻滞的临床效果。方法择期下肢手术90例,随机分为0.2%罗哌卡因(A组)、0.25%罗哌卡因(B组)和0.4%罗哌卡因神经阻滞麻醉组(C组)各30例,采用神经刺激仪定位进行腰丛坐骨神经联合阻滞,A组给予0.2%罗哌卡因25ml坐骨神经阻滞,25ml腰丛神经阻滞;B组给予0.25%罗哌卡因22ml坐骨神经阻滞,20ml腰丛神经阻滞;C组给予0.4%罗哌卡因18ml坐骨神经阻滞,15ml腰丛神经阻滞。比较三组麻醉在起效时间、麻醉效果的区别。结果三组在起效时间上差异无显著性(P>0.05),A、B两组在阻滞效果上明显好于C组,差异有显著性(P<0.05)。结论罗哌卡因施行腰丛坐骨神经阻滞麻醉行下肢手术时,低浓度高容量阻滞效果确切,安全性高,是更好的临床选择。
Objective To evaluate the efficacy of ropivacaine with different concentrations and different volumes on nerve block of the lower limb surgery. Method 90 patients scheduled for the single lower limb operation under lumbar plexus and nerve block were randomly divided into three group： group A（ 0. 2% ropivacaine 25 ml for sciatic nerve block and 25 ml for lumbar plexus nerve block）,group B（ 0. 25% ropivacaine 22 ml for sciatic nerve block and 20 ml for lumbar plexus nerve block） and group C（ 0. 4% ropivacaine 18 ml for sciatic nerve block and 15 ml for lumbar plexus nerve block）,each group has 30 patients. Compare the onset time and block effect between those three groups. Result The onset time of sciatic nerve block in three groups showed no difference. Group A and group B were much better than Group C in block effect with a significant statistic difference. Conclusion Using the same dosage of ropicavaine in sciatic and lumbar plexus nerve block,low concentration with high volume was the better clinical choose.
