Objective: Comparison of rapid-response EEG and surface EEG for seizure risk prediction using 2HELPS2B score. Methods: Five ICU patients with clinical suspicion of seizures were included in this retrospective study. Initially, an 8-channel rapid-response EEG device was applied capturing live stream waveforms. Seizure risk stratification employed the 2HELPS2B scoring methodology. Subsequently, all patients underwent long-term video EEG monitoring (LTM) with standard surface electrodes placed according to the international 10-20 system. Results: Generalized or lateralized epileptiform patterns manifested in all five patients recorded with rapid-response EEG. Based on the seizure stratification tool, (2HELPS2B), patients scored in the range of 1-3 and predicted seizure risk reflected 12-25%. LTM studies immediately following rapid-response EEG confirmed the presence of electrographic seizures in three patients and non-convulsive status epilepticus (NCSE) in the remaining two patients. Conclusion: Seizure predictability using rapid-response EEG may be a useful clinical tool for detection of seizures and subsequent allocation of LTM resources.
