ReviewContinuous EEG monitoring in the neuroscience intensive care unit and emergency department.
This article reviews established, emergent, and potential applications of continuous EEG (CEEG) monitoring in the Neuroscience Intensive Care Unit (NICU) and Emergency Department. In each application, its goal as a neurophysiologic monitor is to extend our powers of observation to detect abnormalities at a reversible stage and to guide timely and physiologically sound interventions. Since this subject was reviewed 5 years ago, the use of CEEG monitoring has become more widespread. ⋯ More recently, it has been found advantageous for targeting management of acute severe head trauma patients. Networking technology has facilitated the implementation and oversight of CEEG monitoring and promises to expand its availability, credibility, and effectiveness. The maturing of CEEG use is reflected in preliminary efforts to assess its cost benefit, cost effectiveness, and impact on patient outcomes.

Case ReportsSuccinylcholine induced hyperkalemia and cardiac arrest death related to an EEG study.
Changes in EEGs during cardiac arrest have been described in detail by many authors; however, mortality because of an EEG has never been reported. The authors report the case of a patient who developed cardiac arrest causally related to administration of succinylcholine for reduction of excessive amounts of myogenic artifact during an EEG. This case indicates the need for caution when doing an EEG study in an intensive care unit setting.

Case ReportsContinuous EEG monitoring in the intensive care unit: early findings and clinical efficacy.
The assessment of the neurocritical care patient involves serial assessment of neurologic status using bedside clinical examination and a variety of periodic neurophysiologic testing. Continuous electroencephalographic (CEEG) monitoring in the intensive care unit offers a unique means to track neurologic function directly and regionally. CEEG is becoming more widespread with a growing but small body of literature. ⋯ The basic tenets of establishing clinical effectiveness for CEEG in the ICU are discussed while acknowledging a need for further study of clinical effectiveness. We review our initial clinical experience of CEEG in 300 patients and outline the clinical efficacy in terms of cost reduction and improvement in outcome (P < 0.01) using CEEG. Finally, several controversial aspects of CEEG are enumerated, and the need for additional study to answer these pressing questions is presented.
