目的 观察超声引导下小儿喙突旁臂丛神经阻滞麻醉效果.方法 选择上肢手术患儿67例随机分为超声引导下喙突旁臂丛阻滞组(观察组34例)和超声引导下肌间沟臂丛神经阻滞组(对照组33例),观察两组操作时间、麻醉起效时间、麻醉效果及并发症.结果 超声引导下喙突旁臂丛神经阻滞组麻醉效果优于超声引导下肌间沟臂丛神经阻滞组,观察组麻醉操作时间及麻醉起效时间短于对照组,观察组并发症少于对照组.结论 超声引导下小儿喙突旁臂丛神经阻滞效果优于超声引导下肌间沟臂丛神经阻滞.%Objective To observe the anesthetic effect of the ultrasound-guided brachial plexus block by subclavian coracoid approach in children for upper limb operation. Methods Sixty-seven patients underwent upper limb operation under the ultrasound-guided brachial plexus block were randomly divided into the subclavian coracoid approach(observation group n=34)and the interscalene approach(control group n=33). After the blockade,the anesthesia performance time,onset time of nerve block,effectiveness of nerve block and complications were recorded. Result The anesthesia performance time and onset time of nerve block in observation group was shorter than control group. The anesthetic effect during surgery of observation group was better than control group. The incidence of complications in observation group were lower than control group's. Conclusion The ultrasound-guided brachial plexus block through subclavian coracoid approach in children for upper limb operation has better anesthetic effect than interscalene approach and fewer complications.
