Critical Care Continuous EEG (CCEEG) is a common procedure to monitor brain function in patients with altered mental status in intensive care units. There is significant variability in patient populations undergoing CCEEG and in technical specifications for CCEEG performance.
The Critical Care Continuous EEG Task Force of the American Clinical Neurophysiology Society developed expert consensus recommendations on the use of CCEEG in critically ill adults and children.
The consensus panel recommends CCEEG for diagnosis of nonconvulsive seizures, nonconvulsive status epilepticus, and other paroxysmal events, and for assessment of the efficacy of therapy for seizures and status epilepticus. The consensus panel suggests CCEEG for identification of ischemia in patients at high risk for cerebral ischemia; for assessment of level of consciousness in patients receiving intravenous sedation or pharmacologically induced coma; and for prognostication in patients after cardiac arrest. For each indication, the consensus panel describes the patient populations for which CCEEG is indicated, evidence supporting use of CCEEG, utility of video and quantitative EEG trends, suggested timing and duration of CCEEG, and suggested frequency of review and interpretation.
CCEEG has an important role in detection of secondary injuries such as seizures and ischemia in critically ill adults and children with altered mental status.
重症监护连续脑电图（CCEEG）是监测重症监护病房中精神状态改变患者脑功能的常用方法。接受CCEEG检查的患者群体以及CCEEG检查的技术规范存在很大差异。
美国临床神经生理学会重症监护连续脑电图特别工作组就CCEEG在重症成人和儿童中的应用制定了专家共识建议。
共识小组推荐使用CCEEG来诊断非惊厥性癫痫、非惊厥性癫痫持续状态和其他阵发性事件，以及评估癫痫和癫痫持续状态的治疗效果。共识小组建议使用CCEEG来识别有脑缺血高风险患者的缺血情况；评估接受静脉镇静或药物诱导昏迷患者的意识水平；以及对心脏骤停后患者进行预后评估。对于每种适应症，共识小组描述了适用CCEEG的患者群体、支持使用CCEEG的证据、视频和定量脑电图趋势的效用、建议的CCEEG检查时间和持续时间，以及建议的复查和解读频率。
CCEEG在检测精神状态改变的重症成人和儿童的继发性损伤（如癫痫和缺血）方面具有重要作用。
