To investigate the effect of electro-acupuncture-anesthesia device (EAAD) as an auxiliary localizing method for brachiplex nerve blocking.
One hundred and twenty patients scheduled for operation in upper limbs were randomly divided into group A and group B, 60 in each group. Bupivacaine 25 ml (0.375% in concentration) was used to block intermuscular plexus brachialis in the operation for anesthesia and EAAD was used for adjunctive localizing in group A, while in group B paresthesia elicitation was used.
In group A, the blocking was complete in 56 cases and incomplete in 4, the anesthesia effect was superior to that in group B, complete in 46, incomplete in 9, and of inefficient in 5 (P < 0.01).
EAAD provides a localizing method for plexus brachialis blocking more precise than paresthesia elicitation.
探讨电针麻醉仪作为臂丛神经阻滞辅助定位方法的效果。
将120例拟行上肢手术的患者随机分为A组和B组，每组60例。A组在手术中使用25 ml布比卡因（浓度为0.375%）进行肌间沟臂丛神经阻滞麻醉，并用电针麻醉仪辅助定位；B组则采用异感法。
A组中56例阻滞完全，4例不完全；麻醉效果优于B组，B组46例完全，9例不完全，5例无效（P < 0.01）。
电针麻醉仪为臂丛神经阻滞提供了一种比异感法更精确的定位方法。
