摘要
目的研究腰椎旁注射局麻药后人体感觉减退的范围。方法坐骨神经痛患者32例,男女各16例,年龄18～71岁,经L_(3～4)椎旁注射0.5%利多卡因15 ml,原体位卧床10 min后采用针刺法测定两侧感觉减退范围。结果L_(3～4)椎旁注射利多卡因后,测得同侧感觉平面减退至T_(7.32±2.09)～L_(3.7±1.19);对侧T_(11.58±4.28)～L_(2.9±0.87)。两组间感觉平面平均减退范围对比差异有统计学意义(P<0.05)。结论一点穿刺椎旁阻滞可以阻滞同侧多根脊神经治疗根性神经痛。
Objective To investigate the influence of lidocaine injected into lumbar paravertebrae on the sensory area. Methods Thirty-two patients with sciatica,male and female 16 cases in each,aged 18-71 years,were injected 0.5% lidocaine 15 ml via L3_4 lumbar paravertebrae. The hypoesthesia levels were determinated 10 minutes after injection. Results Ipsilateral and contralateral hypoesthesia levels appeared from T7.3±2.09 to L3.7±1.19 and from T11.5±4.28 to L2.9±0.87 respectively after lidocaine injected, which were significant difference between the two groups （P 〈0.05 ）. Conclusion One-point lumbar paravertabral block can block ipsilateral multiple spinal nerve root, so it is suitable to treat the ipsilaleral nerve root pain.
