罗哌卡因在小儿臂丛阻滞麻醉中的应用

目的 对比观察0．375％罗哌卡因用于小儿上肢手术臂丛阻滞麻醉的临床效果。方法 选择小儿上肢手术患者36例，随机分为两组（n=18），分别采用氯胺酮基础麻醉下0．375％罗哌卡因用于小儿臂丛阻滞麻醉（A组）或氯胺酮静脉麻醉（B组）。观察两组感觉、运动阻滞效果，生命体征变化，恶心、呕吐等副作用发生情况，以及小儿苏醒状况。结果 A组术中血压、心率和呼吸较接近麻醉前基础值，且术中波动较小，生命体征平稳。B组血压、心率及呼吸率均较术前明显增加，且始终保持在较高水平，随麻醉深浅而有显著波动。结论 0．375％罗哌卡因用于小儿臂丛神经阻滞是一种操作简单，镇痛完善，对循环功能影响小，生命体征平稳，并发症少的麻醉方法。

Ropivacaine used for brachial plexus block on children

Objective To study comparatively the clinical anaesthetic potency and adverse effects to children of 0.375% ropivacaine used for brachial plexus block in upper-limb paediatric surgery.Methods After undergoing basal anesthesia with ketamine,36 children scheduled for hand and forearm surgery were randomly allocated to receive brachial plexus block with 0.375% ropivacaine(group A) and to receive intravenous anesthesia with ketamine(group B).The effect of sensor block and motor block,the changes of vital sings,the occurrence of side effect(nausea and vomiting) and palinesthesia of children were observed.Results The patients in group A kept a steady vital signs,their blood pressure,cardiac and respiration rate were similar to the backgroud level before anesthesia,whereas in group B the blood pressure,cardiac and respiration rate of patients were increased and kept a rather higer level,fluctuated with the depth of anesthesia.Conclusion Ropivacaine used for brachial plexus block in upper-limb paediatric surgery is a simple,feasible,and safe method with anesthetized perfectly and less complication.
