二维成像超声扫描下腰椎选择性神经根阻滞的临床应用研究-中西医结合专业毕业论文.docx

三组神经刺激症状出现率比较无统计学意义(PO．05)。7、A、B、C三组局 三组神经刺激症状出现率比较无统计学意义(PO．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 (P0．05)。 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：二维成像超声选择性神经根阻滞神经阻滞腰椎问盘突 出症腰神经根性痛 Study on the clinical application of selective lumbar nerve root block with two·dimensional imaging of ultrasonic scan Abstract：Objective：To explore the best way to accurately perform a located puncture to the lumbar nerve root with ultrasonic visualization technology；to compare the clinical effect of ultrasonic located puncture block with the traditional puncture block and radiological model guide；to define the safety and superiority of the technology of selective lumbar nerve root block with two—dimensional imaging of ultrasonic scan；to provide a certain 一5． 万方数据 theoretical theoretical basis for the feasibility of the clinical ultrasonically-visualized nerve-block treatment for the patient with lumbsacral radicular pain． Method：90 cases of patients who need to accept selective lumbar nerve root block were selected．These patients were divided into traditional therapy group(group A)，radiologically guided group(group B)and ultrasonically guided group(group C)by the method of single—blind—random，with 3 0 cases fln each group．The comparison of general condition(according to the selecting and excluding standard)among the groups was not statistically significant (PO．05)． Each group of patients were treated with selective lumbar nerve root block periodically,the blocking drug was a mixed liquid of 0．3％lidocaine，1 0mg triamcinolone acetonide and 0．9％normal saline，the position where the puncture needle enters the therapeutic target was determined by the respective nerve root location method for each group，and the needle was drawn back before checked for abnormality．Then block therapy was performed b
