臂丛神经与星状神经节阻滞对上肢（指）血流影响的临床观察

通过对臂丛神经与星状神经节阻滞病人 (SGB)前后上肢 (指 )血流变化的对比观察 ,为临床治疗提供参考依据。将 2 2例病人随机分为A组和B组 ,每组 11例。A组为臂丛神经阻滞 ,B组为SGB ,两组用药相同 ,1%利多卡因 10ml,隔日一次 ,5次为一个疗程。彩色三维经颅多普勒仪监测阻滞前和阻滞后 30min尺、桡动脉血流速度 (cm/s) ,脉搏血氧饱和度仪连续监测阻滞前和阻滞后拇、示、中指 5、10、15、2 0和 30min的脉搏波幅的变化。结果显示 :A组治疗后尺、桡动脉血流平均增快 13cm/s,脉搏波幅平均增高 (9 0 4± 2 12 )mm ;B组治疗后尺、桡动脉血流平均增快 5cm/s ,脉搏波幅平均增高 (3 5 4± 1 42 )mm。两组间比较有显著差异 (P <0 0 1)。提示臂丛神经阻滞对上肢 (指 )血流的增加较星状神经节阻滞显著

THE EFFECTS OF BRACHIAL PLEXUS BLOCK AND SATELLITE GANGLION BLOCK ON THE BLOOD FLOW OF UPPER LIMB,A CLINICAL STUDY

To investigate the effects of brachial plexus block(BPB) and satellite ganglion block(SGB) on the blood flow of upper limb, 22 patients were randomly divided into two groups,and given BPB(group A,n=11) or SGB(group B,n=11) with 1% lidocaine 10 ml every other day for 5 times. Ulnar-radial artery blood flow was measured by using a TCD 30 minutes before and after the block. Finger pulse amplitude was measured by pulse oximeter 5,10,15,20,30 minutes after the block.The average increase in ulnar-radial artery blood flow was 13 cm/s in group A and 5 cm/s in group B. Finger pulse amplitude increased by (9.04±2.12)mm in group A and(3.54±1.42)mm in group B.A significant difference was observed between the two groups (P＜0.01).It suggested that BPB could induce more increase in blood flow of the upper limb than SGB.
