外周神经阻滞在血管外科重症患者下肢手术中的应用

目的采用外周神经刺激器引导行腰丛联合坐骨神经阻滞,评价其在血管外科重症患者(ASA分级为Ⅲ、Ⅳ级)下肢手术中的临床应用价值。方法2006年4月~2007年5月,接受下肢外周神经阻滞的血管外科病人,根据ASA分级分为2组,Ⅰ、Ⅱ级为普通组(C组,n=22),作为对照,Ⅲ、Ⅳ级为重症组(S组,n=25)。2组都在神经刺激器引导下行腰丛联合坐骨神经阻滞,分析两组的麻醉效果,感觉和运动阻滞的起效时间,恢复时间,术中和术后并发症发生情况。结果组间比较,两组的麻醉效果无统计学差异(C组麻醉效果好15例,中4例,差3例;S组麻醉效果好18例,中5例,差2例;U=261.000,P=0.710)。C组68.2%(15/22)的病例,S组72.0%(18/25)的病例都可以很好地满足外科手术对麻醉的要求。组间比较,2组的感觉运动阻滞起效时间无差异(P>0.1),S组腰丛、坐骨神经的感觉和运动恢复时间长于C组(P<0.01)。C组1例术中双侧阻滞,1例术后大腿前面感觉麻木;S组1例术后腹膜后血肿。这些患者经保守治疗均痊愈出院。结论血管外科下肢手术中,ASA分级为Ⅲ、Ⅳ级的重症患者应用外周神经阻滞,可以取得和普通患者同样的麻醉效果...

Peripheral Nerve Block during Lower Limb Procedures for Severe Patients with Vascular Diseases

Objective To evaluate the value of peripheral nerve stimulator-guided lumbar plexus and sciatic block during lower limb procedures for severe patients with vascular diseases (ASA Ⅲ or Ⅳ). Methods From April 2006 to May 2007, 47 patients with vascular diseases scheduled for lower limb procedures were divided into 2 groups according to their ASA grades: control (ASA Ⅰ or Ⅱ, C group, n=22) and severe groups (ASA Ⅲ or Ⅳ, S group, n=25). Peripheral nerve stimulator-guided lumbar plexus and sciatic block was perf...
