To analyze the association between SSEP results and EEG results in comatose patients after cardiac arrest, including the added value of repeated SSEP measurements. ⋯ SSEP and EEG together identify more patients without chance of recovery than one of these alone.

Clinical Trial Observational Study
Influence of midazolam premedication on intraoperative EEG signatures in elderly patients.
To investigate the influence of midazolam premedication on the EEG-spectrum before and during general anesthesia in elderly patients. ⋯ This finding provides further evidence for the role of GABAergic activation in the induction of elevated, frontal α-power during general anesthesia.

Multicenter Study
Propofol does not affect the reliability of early EEG for outcome prediction of comatose patients after cardiac arrest.
To quantify the effects of propofol on the EEG after cardiac arrest and to assess their influence on predictions of outcome. ⋯ We confirm the reliability of EEG-based outcome predictions in propofol-sedated patients after cardiac arrest.
-
To report intraoperative periodic focal epileptiform discharges (PFEDs) during awake craniotomy using high-density electrocorticography (HD-ECoG). ⋯ PFEDs expand our understanding of the interictal-ictal continuum and highlight improved temporo-spatial information obtained from increasing sensor density during intracranial EEG recording.

Under General Anesthesia (GA), age and Burst Suppression (BS) are associated with cognitive postoperative complications, yet how these parameters are related to per-operative EEG and hypnotic doses is unclear. In this prospective study, we address this question comparing age and BS occurrences with a new score (BPTIVA) based on Propofol doses, EEG and alpha-band power spectral densities, evaluated for SEF95 = 8-13 Hz. ⋯ This advocate for an approach based on evaluating the cerebral physiological age («brain age») to predict postoperative cognitive evolution.
