TABLE 1.
Clinical Profile of Patients with Evidence of EEG Periodic Discharges
| Patient | Age, yr | Gender | Medical History | Intervention | Days Intubated at Time of EEG | EEG Interpretation | Clinical Outcome |
|---|---|---|---|---|---|---|---|
| 1 | 58 | M | Coma, face and eye myoclonus |
Ventilator, deep sedation (propofol, fentanyl), ECMO, lumbar puncture |
4 | Generalized bilateral frontal intermittent symmetric biphasic delta, theta activity | Died 8 days after EEG performed |
| 2 | 70 | M | Delayed awakening, cardiac arrest | Ventilator, not sedated | 8 | Generalized bilateral frontal high‐amplitude symmetric biphasic delta, theta activity | Died 3 days after EEG performed |
| 3 | 70 | M |
Poor arousal epilepsy? |
Ventilator, mild sedation (midazolam), CT scan | 6 | Lateralized right focal frontal high‐amplitude symmetric biphasic delta symmetric | Remains hospitalized in ICU |
| 4 | 70 | M | Coma, face myoclonus | Ventilator, deep sedation (propofol, fentanyl), renal dialysis | 12 | Generalized biphasic delta asymmetric frontal predominance | Died 9 days after EEG performed |
| 5 | 67 | F | Confusion, lethargy | MRI, lumbar puncture | N/A | Generalized frontal slowing, symmetric biphasic delta, theta activity | Remains hospitalized on ward, significant cognitive deficit |
CT = computed tomography; ECMO = extracorporeal membrane oxygenation; EEG = electroencephalographic; F = female; ICU = intensive care unit; M = male; MRI = magnetic resonance imaging; N/A = not applicable.
