脊髓损伤完全与否与体感诱发电位的关系

目的 探讨用于鉴别脊髓是否为完全性损伤的客观检查方法。方法 依据脊髓损伤神经学分类国际标准，将100例脊髓损伤患者分为完全性和不完全性损伤两组；同时根据体感诱发电位检查结果，将上述病例分为完全性和不完全性传导阻滞两组，并对两者进行比较。结果 是否为不完全性或完全性脊髓损伤与其体感诱发电位（SEP）是否出现两者之间具有一致性。SEP用于判断脊髓损伤完全与否的敏感性为0.75，特异性为0.94，准确性为0.89。结论 SEP是否出现完全性传导阻滞可作为判断脊髓是否为完全性损伤的一项客观有用的标准。

A prelimincary research on the relationship between SEP and severity of spinal cord injury

Objective To explore an objective method for evaluating the severity of spinal cord injury (SCI). Methods One hundred SCI patients were recruited and divided, according to the International Standards for Neurological Classification of Spinal Cord Injury, into two groups:complete or incomplete injury and they were sub-divided into two subgroups: patients with complete or incomplete conduction block of somatosensory evoked potentials (SEP) . The findings in relation to the two types of SCI were compared between these groups. Results Complete or incomplete SCI was highly correlated to the presence or absence of SEP, i. e. SEP could hardly be detected in patient with complete SCI, while in patient with incomplete SCI, the SEP conduction time might be either normal or delayed. Conclusion Complete or incomplete conduction block in SEP can be used as an objective and reliable criterion for evaluating the severity of SCI.
