客观化
我们的目的是研究强直性脑神经刺激是否能提高经颅运动诱发电位(MEP)的波幅。
方法
选择30例异丙酚-芬太尼复合部分神经肌肉阻滞下行开颅手术的患者。对照和强直后MEP(c-MEP和p-MEP)监测均由5个脉冲组成的序列传递到C3或C4。1 S强直刺激尺神经和面神经后，记录靶肌肉c-MEP和p-MEP。配对MEP的波幅用Wilcoxon符号秩检验法进行比较。
结果
分别对面神经进行强直刺激时，拇短展肌、眼轮匝肌或口轮匝肌的p-MEP波幅与c-MEP波幅相近。分别对尺神经进行强直刺激时，拇短展肌的p-MEP波幅较c-MEP显著增大，但眼轮匝肌和口轮匝肌的p-MEP波幅无显著差异。
结论
我们发现，只有强直刺激尺神经，而不是面神经，才能使经颅手部MEP的波幅增大。强直刺激周围神经引起的MEP波幅增加似乎起源于皮质下水平，而不是运动皮质。
OBJECTIVE
Our objective was to examine whether prior tetanic stimulation of cranial nerves enhances the amplitudes of transcranial motor-evoked potentials (MEPs).
METHODS
Thirty patients undergoing elective craniotomy under propofol-fentanyl anesthesia with partial neuromuscular blockade were enrolled. Both control and posttetanic MEPs (c-MEPs and p-MEPs) monitoring were performed with a train of five pulses delivered to C3 or C4. c-MEPs were recorded from target muscles and p-MEPs were obtained 1 s after tetanic stimulation to the ulnar nerves and facial nerves. The amplitudes of paired MEPs were compared with Wilcoxon's signed rank test.
RESULTS
When tetanic stimulation was separately applied to the facial nerves, amplitudes of p-MEPs from abductor pollicis brevis, orbicularis oculi or oris were similar with those of c-MEPs. When tetanic stimulations were separately applied to the ulnar nerves, the amplitudes of p-MEPs from the abductor pollicis brevis but not orbicularis oculi or oris were significantly enlarged compared with c-MEP.
CONCLUSIONS
We found that only prior tetanic stimulation of ulnar nerve but not facial nerve could enlarge the amplitudes of trancranial hand MEPs. Augmentation of MEP amplitude via prior tetanic stimulation of peripheral nerve seems to originate from the subcortical level but not motor cortex.
