2种坐骨神经阻滞引导法在麻醉药分布方面的对比分析

Comparative analysis of two guidance methods in sciatic nerve block in terms of anesthetic distribution

目的 :回顾性分析坐骨神经干周围麻醉药的分布情况,探讨超声引导法的应用优势。方法 :受试患者(观察组为A组,对照组为B组)分别由超声和神经刺激仪引导注射麻醉药,由超声医师根据麻醉药分布情况进行评分,等级资料采用半定量分析法,阻滞成功率采用χ~2检验。结果:超声引导法所获得的评分高于神经刺激仪引导的评分(P<0.05)。结论:在坐骨神经干周围麻醉药分布情况方面,超声引导法优于神经刺激仪引导法。

Objective：The distribution of anesthetic around the sciatic nerve was retrospectively analyzed,and the advantages of ultrasound guidance were discussed. Methods：The patients were divided into group A and group B. The anesthesia was injected by the ultrasound guidance and the nerve stimulator guidance,respectively. The distribution of anesthetic around the sciatic nerve was scored by the ultrasound physicians. Ranked data were used with semi-quantitative analysis,the success rate of block was used with χ^2 test. Results：The scores obtained by the ultrasound guidance method were higher than those by the nerve stimulator guidance method（P〈0.05）. Conclusion：The ultrasound-guided method is superior to the nerve-stimulator method to analysis the anesthetic distribution around the sciatic nerve.
