Non-convulsive seizures and status epilepticus are common in brain-injured patients in intensive care units. Continuous electroencephalography (cEEG) monitoring is the most sensitive means of their detection. In centres where cEEG is unavailable, routine EEG is often utilized for diagnosis although its sensitivity is lower.
To establish the rate of electrographic seizure detection in ICU using routine EEG.
We identified all routine EEGs performed within a general adult ICU in Ireland over 3 years, and analyzed the clinical and EEG data.
Fifty-two patients underwent single or repeated EEG evaluation during the time period. Epileptiform abnormalities were evident in 15%, periodic abnormalities in 14%, and electrographic seizures in just one patient (2%) in their first or only routine EEG recording.
The rate of electrographic seizure detection by routine EEG in a general ICU is lower than anticipated. Earlier and more prolonged recordings are needed in this setting.
非惊厥性发作和癫痫持续状态在重症监护病房的脑损伤患者中很常见。连续脑电图（cEEG）监测是其检测最敏感的手段。在 cEEG 不可用的中心，常使用常规脑电图进行诊断，尽管其敏感性较低。
确定常规脑电图在 ICU 中检测电描记术发作的发生率。
我们确定了在爱尔兰一个普通成人 ICU 中进行的所有常规脑电图，并分析了临床和脑电图数据。
在研究期间，52 名患者进行了单次或重复脑电图评估。在首次或唯一的常规脑电图记录中，15%的患者出现癫痫样异常，14%的患者出现周期性异常，仅有 1 名患者（2%）出现电描记术发作。
在普通 ICU 中，常规脑电图检测电描记术发作的发生率低于预期。在这种情况下，需要更早和更长时间的记录。
