曲马多加入利多卡因液中用于腋路臂丛神经阻滞的临床观察

Clinical observation of tramadol added to lidocaine solution for axillary brachial plexus block

目的 观察曲马多加入利多卡因液中对腋路臂丛神经阻滞的影响。方法 3 0例病人 ,ASAⅠ～Ⅱ级随机分成三组 ,每组 10例。A组 :1.3 %利多卡因 3 0ml +曲马多 10 0mg ;B组 :1.3 %利多卡因 3 0ml + 0 .9%氯化钠 2ml;C组 :1.3 %利多卡因 3 0ml + 0 .9%氯化钠 2ml +曲马多 10 0mg静脉注射。麻醉前 ,注药后 5、10、60、12 0、180和 3 60min时记录感觉阻滞、运动阻滞效果和血压、心率、心电图、血氧饱和度。结果 (1)各组间感觉阻滞和运动阻滞的显效时间没有差异 ;(2 )感觉阻滞和运动阻滞的持续时间比较 ,A组显著长于B、C组 ,P <0 .0 1。结论 腋路臂丛阻滞时 ,曲马多 10 0mg加入 1.3 %利多卡因液中 。

Objective To observe the effect of tramadol added to lidocaine solution on axillary brachial plexus block.Methods 30 patients (ASA:Ⅰ～Ⅱ) were randomly divided into three groups,10 patients in each group.Group A:1.3% lidocaine 30 ml with tramadol 100 mg;group B:1.3% lidocaine 30 ml with 0.9% NaCl 2 ml;group C:1.3% lidocaine 30 ml with 0.9% NaCl 2 ml and tramadol 100 mg(i.v).Sensory block,motor block and BP,HR,SpO 2 were recorded before and 5,10,30,60,120,180 amd 360 min after local anethetic injection.Results (1)There were no differences in onset of sensory and motor block among groups;(2)The duration of sensory and motor block was significantly longer in group A than that in group B and group C (P<0.01).Conclusion The mixture of tramadol 100 mg with 1.3% lidocaine can obviously improve the effect of block and prolong the duration of analgesic effect.
