The indications of emergency electroencephalogram (eEEG) were defined by a French consensus conference in May 1996. We retrospectively confronted the recommendations with the actual requests for emergency EEG in our University hospital, in order to determine the contribution of the eEEG in the most frequent clinical situations encountered.
Three hundred and twenty nine consecutive eEEGs over a 6-months period were retrospectively analyzed.
The most frequent indications were presumption of brain death (13%), convulsive status epilepticus after treatment (12.1%), and suspicion of nonconvulsive epilepticus status (10.6%). More than one third of the requests (38.6%) were not in conformity with the recommendations of the consensus conference. The contribution of the EEG is much improved by the application of the consensual criteria. Thus, the EEG remains essential for the management of convulsive status epilepticus after treatment, to seek a subtle epilepticus status or a nonconvulsive epilepticus status. Conversely, the EEG did not prove useful in emergency after a transient loss or alteration of consciousness or a focal, non-febrile, neurological transient or permanent deficit.
1996年5月，法国召开了一次共识会议，对紧急脑电图（eEEG）的适应症进行了定义。我们回顾性地将这些建议与我校医院紧急脑电图的实际需求进行对比，以确定eEEG在常见临床情况下的作用。
回顾性分析了6个月内连续进行的329例紧急脑电图检查。
最常见的适应症是脑死亡推定（13%）、治疗后惊厥性癫痫持续状态（12.1%）以及非惊厥性癫痫持续状态疑似（10.6%）。超过三分之一的检查申请（38.6%）不符合共识会议的建议。通过应用共识标准，脑电图的作用得到了很大改善。因此，脑电图对于治疗后惊厥性癫痫持续状态的管理、寻找隐匿性癫痫持续状态或非惊厥性癫痫持续状态仍然至关重要。相反，脑电图在意识短暂丧失或改变、局灶性、非热性、神经系统短暂或永久性缺损后的紧急情况下并无用处。
