0.5%罗哌卡因用于神经刺激仪引导下的臂丛神经阻滞的临床研究

目的探讨0.5%罗哌卡因用于神经刺激仪引导下的臂丛神经阻滞的麻醉效果和安全性。方法54例ASAⅠ~Ⅱ及行择期前臂或手部手术的患者分为实验组(n=28)和对照组(n=26)。实验组局麻药物使用0.5%罗哌卡因和1%利多卡因,对照组麻醉药物使用0.15%丁卡因及1.33%利多卡因混合液。比较两组患者在不同时间点的感觉、运动和痛觉评分及术后随访情况。结果实验组与对照组术中各不同时间点的感觉、运动和痛觉评分没有显著差异。术后镇痛维持实验组长于对照组,两者有显著性差异(P<0.05)。结论臂丛神经阻滞使用0.05%罗哌卡因可取得满意的麻醉效果并具有较高的安全性。

Clinical study of 0.5% ropivacalne for nerve stimulator-guided brachial plexus block

OBJECTIVE To explore the anesthesia effect and safety of ropivacaine in nerve stim lator guided brachial plexus block.METHODS Fifty-four patients,ASA physical status of Ⅰ～Ⅱ,undergoing selective forearm and hand operation were randomly allocated into two groups:experimental group(n=28)and control group(n=26).0.5% ropivacaine-1% lidocaine and 0.15% tetracaine-1.33% lidocaine were used in two groups,respectively,The sensory scale scores,motor scale scores,visual analogue pain scores were recorded in different time points.RESULTS During the operations,the sensory scale scores,the motor scale scores and the visual analogue pain scores in these two groups were similar.Compared with tetracaine-lidocaine,the time of analgesia in ropivacaine groups was longer(P<0.01).CONCLUSION The trials showed that 0.5% Ropivacaine in brachial plexus block can produce a satisfactory anesthesia effect and had a great security.
