神经刺激器在腰丛-坐骨神经联合阻滞的下肢手术中作用

Effect of nerve stimulator on combined lumbar plexus-sciatic nerve block in leg surgery

目的观察神经刺激器定位腰丛-坐骨神经联合阻滞行下肢手术的麻醉效果。方法选择下肢手术患者20例,其中男性12例,女性8例;年龄18～76岁;美国麻醉医师协会(ASA)Ⅰ～Ⅲ级。使用神经刺激器定位腰丛-坐骨神经,并施行麻醉,观察和记录麻醉起效时间、麻醉效果和术后镇痛持续时间,观察不良反应。结果20例中18例神经阻滞效果满意(优),2例效果稍差(良)。麻醉前、麻醉后及术后收缩压(SBP)、舒张压(DBP)及心率(HR)差异无统计学意义(P>0.05)。术中及术后随访未见不良反应发生。结论神经刺激器定位腰丛-坐骨神经联合阻滞行下肢手术时麻醉效果满意,并发症少。

Objective To observe the anesthesic efficacy of nerve stimulator in combined lumbar plexus-sciatic nerve block for leg surgery. Methods A total of 20 patients （male 12,female 8; aged 18 -76 years）,were performed leg surgery with American Society of Anesthesiologists（ASA） Ⅰ to Ⅲ. The time of performing anesthesia,occurring of anesthesic effect and duration of post-operative analgesia were observed and recorded. Results Of these patients 18 cases had satisfactory efficacy of the nerve block. But 2 patients were unsatisfied effect. The difference of systolic blood pressure（SBP）,diastolic blood pressure（DBP）,heart rate（HR） before and after anesthesia and post operation had no statistical significance（P 〉 0.05）. There was no complication occurred during operation and postoperation. Conclusion The clinical efficacy of combined lumbar plexus-sciatic nerve block for leg surgery performed under the guidance of a nerve stimulator is satisfactory and fewer complications has found.
