Yield of repeated intermittent EEG for seizure detection in critically ill adults

Continuous Electroencephalography Monitoring in Adults in the Intensive Care Unit

“…Traditional 30-60 min EEG recordings identify non-convulsive seizures in only 45-58% of patients in whom seizures are eventually recorded. About 80-95% of patients with non-convulsive seizures can be identified within 24-48 h [18,19]. In 625 critically ill patients, the probability of seizures was strongly influenced by findings detected very early in the course of monitoring.…”

Guidance for clinical neurophysiology examination throughout the COVID-19 pandemic. Latin American chapter of the IFCN task force – COVID-19

“…Performance of the study should be preferred through hospitalization if required by the emergency of the medical condition, and the result of the examination should impact decision-making in the treatment. An example is non-convulsive status epilepticus in children or adults (Fogang et al, 2017;Sánchez Fernández et al, 2017). If an outpatient study is needed in a private or public clinic, the guidelines for the protection of the HP and the prevention of transmission through the guidelines for disinfection of the facilities, equipment and material referred to in sections 13, 14 and 15 below shall be followed.…”

Electroencephalogram Monitoring in Critical Care

“…21 Spot EEG identifies only 45 to 58% of patients who eventually developed seizures. 29 Patients should be ideally recorded for at least 24 hours, and for 48 hours if comatose. 4 In a series of adult ICU patients with nonconvulsive seizures, 87% of patients experienced their first recorded seizure in the first 24 hours of EEG monitoring.…”
