体感诱发电位监测在脊柱侧弯后路一期小切口矫形术中的临床研究．

目的评价体感诱发电位（SEP）在脊柱侧弯后路一期小切口手术中的临床应用价值。方法对70例进行后路一期小切口手术的脊柱侧弯患者进行体感诱发电位监测，记录手术前、中、后的诱发电位变化并分析原因。结果68例患者术中电位无明显变化，2例患者诱发电位出现异常。结论体感诱发电位具有简便、灵敏和及时监护的特点，能早期预告后路一期小切口手术中的神经损伤，避免神经损伤，提高手术的安全性。

The Clinical Study of Monitoring Posterior birst Stage Minimal Incision Surgery by Somatoosensory Evoked Potential

Objective To study the clinical application value of somatosensory evoked potential（SEP） monitoring during posterior first stage minimal incision surgery. Methods 70 cases under posterior first stage minimal incision surgery were monitored by SEP, and recorded and analysed the changes of evoked potentials during preoperative, intraoperative and postoperative. Result There were 2 cases in this group of patients with abnormal evoked potentials and the others had no significant changes. Conclusion As a simple and instant monitor method, SEP monitor is able to warn nerve damage early in posterior first stage minimal incision surgery and enhance the security of surgery.
