罗比卡因应用于臂丛神经阻滞的临床研究

Clinical Study on Conduction Blockade of Brachial Plexas Nerve with Ropivacaine

目的 :用不同浓度罗比卡因行臂丛神经阻滞 ,以研究不同浓度罗比卡因对臂丛神经痛觉和运动的阻滞作用。方法 :60例因上肢疾病需行手术治疗的住院患者 ,随机分为三组 ,每组 2 0例 :A组 0 .2 5%布比卡因 30 ml;B组 0 .2 5%罗比卡因 30 ml;C组 0 .2 %罗比卡因 30 ml。采用相同麻醉方法后比较三组患者麻醉效果。结果 :与 A组相比 ,B、C组麻醉完全起效时间延长 ;B组感觉阻滞完全 ,维持时间相仿 ,运动阻滞恢复快 ;C组感觉阻滞完全 ,感觉与运动阻滞维持时间均短。结论 :与 0 .2 5%布比卡因相比 ,罗比卡因行臂丛神经阻滞时 ,有较明显的运动感觉阻滞分离。

Objective:To study the blockade effect on pain sense and motion in brachial plexus nerve with the different concentrations of Ropivacaine.Methods:60 cases who were carried out operation on upper arm were randomly divided into three groups.Each group contained 20 cases.Group A was treated with Bupivacaine,group B treated with 0.25% Ropivacaine and group C with 0.2% Ropivacaine.The effects in the three groups were compared after the same anaesthetization was carried out.Compared with group A,group B and C had the longer anaesthetic time.The whole sense blockade in group B was found and the motion blockade was recovered quickly.In group C,the sense blockade was perfect,but the constant time of both sense and motion blockade was short.Conclusion:Compared with Bupivacaine,Ropivacaine has the significant division between the sense and motion blockade while the anaesthetization of brachial plexus nerve is carried out.
