Abstract

A prospective study of EEG changes following metrizamide myelography was made on 34 patients aged 17-79 years. EEGs were recorded just before and 22-26 hours after myelography. Usually 8-10 ml of metrizamide was injected by either lumbar or lateral cervical puncture. The concentration of metrizamide was relatively high. EEGs were abnormal in 15 out of the 20 patients whose baseline EEGs were normal. EEGs deteriorated in 10 of the 14 patients whose control tracings were abnormal. High voltage delta activity and/or a great deal of theta activity were common abnormalities. Three patients showed triphasic waves. No relationships were found between the EEG changes and clinical variables. But central nervous system involvements by metrizamide tended to be accompanied by a severe EEG slowing.

摘要

对34名年龄在17至79岁之间的患者进行了一项关于甲泛葡胺脊髓造影术后脑电图（EEG）变化的前瞻性研究。在脊髓造影术前及术后22至26小时记录脑电图。通常通过腰椎穿刺或颈外侧穿刺注入8至10毫升甲泛葡胺。甲泛葡胺的浓度相对较高。在基线脑电图正常的20名患者中，有15名患者的脑电图出现异常。在对照描记异常的14名患者中，有10名患者的脑电图恶化。高电压δ活动和/或大量θ活动是常见的异常情况。三名患者出现三相波。未发现脑电图变化与临床变量之间存在关联。但甲泛葡胺引起的中枢神经系统受累往往伴有严重的脑电图减慢。
