In the past 15 years, the increased availability and use of continuous electroencephalography (cEEG) in critically ill patients has substantially changed our understanding of the injured brain. We have become increasingly aware that electrographic seizures in this population may have only subtle or no clinical signs and that cEEG greatly increases the likelihood of detecting these seizures. This review highlights the rationale behind using cEEG rather than routine EEG for detection of nonconvulsive seizures and nonconvulsive status epilepticus in critically ill patients and defines which patients are at greatest risk. It also describes other applications of cEEG in the intensive care unit and how it may play an important role in monitoring brain function.
在过去的 15 年中，连续脑电图（cEEG）在危重病患者中的可用性和使用的增加，极大地改变了我们对受损大脑的理解。我们越来越意识到，该人群中的电发作可能只有轻微或没有临床体征，而 cEEG 大大增加了检测这些发作的可能性。本综述强调了在危重病患者中使用 cEEG 而不是常规 EEG 来检测非惊厥性发作和非惊厥性癫痫持续状态的基本原理，并确定了哪些患者的风险最大。它还描述了 cEEG 在重症监护病房中的其他应用以及它如何在监测脑功能方面发挥重要作用。
