1、三组神经刺激症状出现率比较无统计学意义(P>O．05)。7、A、B、C三组局部血肿出现率分别为26．02％，16．92％，7．69％，组间比较均有统计学意义(P<0．05)。结论：通过二维成像超声扫描实施选择性腰神经根阻滞技术，发挥二维成像超声扫描非侵入性、无射线照射、方便携带、需要较少准备即可直接应用、易教易学等优点，同时在治疗过程中超声引导直接连续可观的视野下操作进针，并实时观测注射药物的沉积和蔓延，易于鉴别血管和神经，避免放射引导中造影剂的应用，降低血管和神经内注射药物的风险。超声可视化等同于放射可视化引导神经阻滞的治疗效果且更具应用优势，是一种环保、安全、有效的可视化治疗技术。关键词：
