AbstractBenign epileptiform variants (BEVs) are often noted in routine electroencephalogram (EEG) monitoring and are sometimes misinterpreted as epileptiform discharges. Six and 14 Hz positive spikes are one of such BEVs seen especially in children. However, these variants can also be seen in intensive care unit EEG recordings. Here, we have reviewed the history and electrical details of these 6 and 14 Hz variants with their clinical significance.

Video-EEG monitoring is often used to detect nonconvulsive status epilepticus (NCSE) in critical care patients. Short recording durations may fail to detect seizures. In this study, we investigated the time required to record the first ictal event, and whether it could be correlated with some clinical or EEG parameters. Video-EEG recordings of patients who were followed up in our neurological intensive care unit were evaluated retrospectively. The EEG recordings of patients with NCSE were reviewed to determine the timing of the first seizure occurrence. Demographic data and EEG findings were obtained from patient charts and EEG reports. Possible correlations between the presence of periodic discharges (PD), Glasgow Coma Scale (GCS) score and early seizure detection (defined as a seizure within the first hour of recording) were explored statistically. Out of 200 patients who underwent video-EEG monitoring, we identified 30 cases (15%; 18 male, 12 female; age 24-86 years; mean recording duration 99 hours) with NCSE. The first seizure was recorded within 0 to 1 hour in 22 patients (73%) and within 1 to 12 hours in 6 patients (22%). Interictal PDs were identified in 19 patients (63%). GCS score was ≤8 in 16 patients (53%). There was no correlation between early seizure detection and PDs (p=1.0) or GCS score ( P = .22). In our study, >90% of the seizures were captured within 12 hours. This finding suggests that most of the NCSE cases can be identified even in centers with limited resources. The presence or absence of PDs or GCS score does not predict the timing of the first seizure.

AbstractSeizures are common in critically ill patients. Electroencephalogram (EEG) is a tool that enables clinicians to provide continuous brain monitoring and to guide treatment decisions—brain telemetry. EEG monitoring has particular utility in the intensive care unit as most seizures in this setting are nonconvulsive. Despite the increased use of EEG monitoring in the critical care unit, it remains underutilized. In this review, we summarize the utility of EEG and different EEG modalities to monitor patients in the critical care setting.

Epidemics of bacteraemia and wound infection have been associated with the infusion of bacterially contaminated propofol administered during anaesthesia. We conducted an observational study to determine the incidence and clinical significance of administration of potentially contaminated propofol to patients in an ICU setting. One hundred patients received a total of 302 infusions of propofol. Eighteen episodes of possible contamination of propofol syringes were identified, but in all cases contamination was by a low-grade virulence pathogen. There were no episodes of clinical infection or colonization which could be attributed to the administration of contaminated propofol. During the routine use of propofol to provide sedation in ICU patients the risk of nosocomial infection secondary to contamination of propofol is extremely low.

AbstractBackground:Electroencephalography (EEG) is playing an increasingly important role in the management of comatose patients in the intensive care unit.Methods:The techniques of EEG monitoring are reviewed. Initially, standard, discontinuous recordings were performed in intensive care units (ICUs). Later, continuous displays of “raw EEG” (CEEG) were used. More recently, the addition of quantitative techniques allowed for more effective reading.Results and Conclusions:Applications of continuous EEG to clinical problems are discussed. The most useful role of CEEG appears to be the detection and management of nonconvulsive seizures. There is a need for controlled studies to assess the role for CEEG in neuro-ICUs and general ICUs.

Electroencephalogram Eeg

OBJECTIVES: To assess the frequency of electroencephalogram (EEG) requests in the emergency room (ER) and intensive care unit (ICU) for patients with impairment of consciousness (IC) and its impact in the diagnosis and management. METHODS: We followed patients who underwent routine EEG from ER and ICU with IC until discharge or death. RESULTS: During the study, 1679 EEGs were performed, with 149 (8.9%) from ER and ICU. We included 65 patients and 94 EEGs to analyze. Epileptiform activity was present in 42 (44.7%). EEG results changed clinical management in 72.2% of patients. The main reason for EEG requisition was unexplained IC, representing 36.3% of all EEGs analyzed. Eleven (33%) of these had epileptiform activity. CONCLUSION: EEG is underused in the acute setting. The frequency of epileptiform activity was high in patients with unexplained IC. EEG was helpful in confirming or ruling out the suspected initial diagnosis and changing medical management in 72% of patients.
