甲磺酸罗哌卡因用于幼儿臂丛神经阻滞的浓度选择

Ropivacaine Mesylate Injection Uses in the Density Choice which a Baby Arm Clump of Nerve Hinders

目的:探讨甲磺酸罗哌卡因用于幼儿臂丛神经阻滞的最佳浓度。方法:将80例行臂丛神经阻滞的幼儿患者,随机分为4组,每组20例。均在全麻下用甲磺酸罗哌卡因。浓度分别为0.33%、0.25%、0.20%、0.167%,容量为1ml/kg,观察临床麻醉效果及不良反应。结果:0.167%组浓度较低,阻滞效果较其他三组差。0.33%组有2例出现肢体不自主运动。结论:0.2%、0.25%、0.33%甲磺酸罗哌卡因均可以安全地用于幼儿臂丛神经阻滞,0.33%甲磺酸罗哌卡因要注意防止局麻药中毒。

Objective：Discusses a baby arm clump of nerve hinder with ropivacaine mesylate injection of density choice.Methods：Baby patient who hinders 80 routine arm clump of nerve,divided into 4 groups stochastically,each group of 20 examples.Uses ropivacaine mesylate injection under the general anesthesia.The density respectively is 0.33%,0.25%,0.20%,0.167%,and the capacity is 1ml/kg.Observation clinical anesthesia effect and the side effect.Results： The density of 0.167% group hinder effect difference to compare other three groups.0.33% group have 2 cases to present the body involuntary movement.Conclusion：0.2%,0.25%,0.33% ropivacaine mesylate injection may safe use in a baby arm clump of nerve hindering.0.33% ropivacaine mesylate injection must pay attention to the prevention local anesthetic poisoning.
