Isoelectric electroencephalogram in conformance with clinical findings is strongly suggestive of brain death. In clinical practice, isoelectric electroencephalogram in not-brain-dead patients is rarely seen. We report on a 53-year-old patient who suffered ischaemic encephalopathy after cardiopulmonary arrest. He had residual brainstem function with sufficient spontaneous breathing and evidence of cerebral blood flow on single photon emission computed tomography scan, but his electroencephalogram was isoelectric. He survived this condition for more than 7 weeks. This case demonstrates that isoelectric electroencephalogram can not be equated with brain death, and that in prognostic assessment both clinical findings and supportive technical methods are mandatory.
符合临床检查结果的等电位脑电图强烈提示脑死亡。在临床实践中，非脑死亡患者出现等电位脑电图的情况极为罕见。我们报告了一名53岁的患者，该患者在心肺骤停后发生缺血性脑病。他保留了脑干功能，有足够的自主呼吸，并且单光子发射计算机断层扫描显示有脑血流迹象，但他的脑电图呈等电位。他在这种状况下存活了7周多。该病例表明，等电位脑电图不能等同于脑死亡，并且在预后评估中，临床检查结果和辅助技术方法都是必不可少的。
