神经刺激器引导下不同浓度罗派卡因肌间沟臂丛麻醉的效果观察

Effect observation on different concentrations of ropivacaine interscalene brachial plexus anesthesia guided by nerve stimulator

目的:观察神经刺激器引导下不同浓度罗派卡因肌间沟臂丛麻醉的效果。方法:我院2016年5月-2017年5月收治的69例神经刺激器引导下罗哌卡因肌间沟臂丛麻醉的患者,按照罗哌卡因给药浓度不同将所有患者均分为A、B、C三组,其中A组患者给予30m L0.25%罗哌卡因,B组患者给予30m L0.375%罗哌卡因,C组患者给予30m L0.5%罗哌卡因,观察三组患者麻醉效果。结果:C组患者麻醉起效时间明显早于B组和A组,且C组麻醉持续时间明显长于B组、A组,C组患者麻醉优良率明显优于B、A两组,A组患者不良反应发生率明显少于B、C两组,数据具有统计学意义(P<0.05)。结论:对于神经刺激器引导下肌间沟臂丛麻醉的患者罗哌卡因浓度越高麻醉起效时间越短、麻醉持续时间越长,麻醉效果越好,但是个体不良反应发生率也随之升高。

Objective: To observe the effect of different concentrations of ropivacaine interscalene brachial plexus anesthesia guided by nerve stimulator. Methods: 69 cases of ropivacaine interscalene brachial plexus anesthesia guided by nerve stimulator treated in our hospital from May 2016 to May 2017 were divided into A, B, C groups according to the concentration of ropivacaine. A group was treated with 30 m L 0.25% ropivacaine, B group was treated with 30 m L 0.375% ropivacaine while C group was treated with 30 m L 0.5% ropivacaine, the anesthesia effect in three groups was observed. Results: The onset time in C group was significantly earlier than that in B group and A group, and the duration in C group was significantly longer than that in B group and A group, the anesthesia excellent rate in C group was significantly higher than that in B group and A group, the adverse reaction rate in A group was significantly less than that in the B group and C group, the difference was statistical significance(P<0.O5). Conclusion: Concentration of ropivacaine in nerve stimulator guided interscalene brachial plexus anesthesia shows shorter onset time of anesthesia and the longer anesthesia duration, and a better anesthesia effect, but the adverse reaction of the individual rate increased.
