We performed an observational volunteer study to document an ultrasound-guided evoked motor response blockade of the deep peroneal nerve.
Sixteen volunteers had deep peroneal nerve blocks in each foot. After visualization of the artery and the deep peroneal nerve with an ultrasound, the nerve was stimulated with a nerve stimulator. Evoked motor responses and/or paresthesia were noted before injection of the local anesthetic.
Any evoked motor response (extension of the toes or muscle contractions on the dorsum of the lateral aspect of the foot) or elicitation of paresthesia resulted in complete sensory blockade of the web between the big toe and second toe.
Visualization of the deep peroneal nerve with ultrasound followed by elicitation of an evoked motor response, or paresthesia, predicts successful blockade of the deep peroneal nerve.
我们进行了一项观察性志愿者研究，以记录超声引导下腓深神经诱发运动反应阻滞情况。
16名志愿者每只脚均接受腓深神经阻滞。在超声显示动脉和腓深神经后，用神经刺激器刺激神经。在注射局部麻醉剂前记录诱发运动反应和/或感觉异常。
任何诱发运动反应（足趾伸展或足外侧背侧肌肉收缩）或感觉异常的引出均导致拇趾与第二趾间蹼的完全感觉阻滞。
超声显示腓深神经后诱发运动反应或感觉异常可预测腓深神经阻滞成功。
