continuous EEG monitoring
Also written as: cEEG — continuous electroencephalographic monitoring
Extended electroencephalographic recording over hours to days for seizure detection.
Full Definition
Continuous EEG monitoring (cEEG) involves prolonged electroencephalographic recording, typically lasting 24 hours or more, to detect seizures and monitor brain function in critically ill patients. This technique is essential in intensive care units for identifying non-convulsive seizures and status epilepticus, which may occur in up to 20% of comatose patients. The monitoring requires specialized electrode application, artifact recognition, and interpretation by trained neurophysiologists. Modern systems often incorporate automated seizure detection algorithms and compressed spectral arrays to assist with pattern recognition over extended recording periods.
Usage
Usage note: Lowercase 'c' in cEEG is standard abbreviation format.
