Neurophysiologie clinique = Clinical neurophysiology

The contribution of clinical neurophysiology in the neurological prognosis of hypoxic-ischemic coma has been well established in adults: the bilateral absence of cortical somatosensory evoked potentials (SEP) is considered the single best indicator of adverse outcome, while the presence of the auditory mismatch negativity (MMN) is thought to herald arousal. ⋯ This case illustrates the particular significance of SEP and MMN together with EEG in gaining prognostic information, even in sedated and hypothermic patients, and encourages systematic study of these prognostic tools in paediatric postanoxic coma.

To provide a consensus of European leading authorities about the optimal use of clinical neurophysiological (CN) tests (electroencephalogram [EEG]; evoked potentials [EP]; electroneuromyography [ENMG]) in the intensive care unit (ICU) and, particularly, about the way to make these tests clinically useful for the management of individual patients. ⋯ CN provides quantitative functional assessment of the nervous system. It can be used in sedated or curarized patients. Therefore, it should play a major role in the individual assessment of ICU patients.

To monitor acute brain injury in the neurological intensive care unit (NICU), we used EEG and somatosensory evoked potentials (SEP) in combination to achieve more accuracy in detecting brain function deterioration. ⋯ We observed 3% of nonconvulsive status epilepticus compared to 18% of neurological deterioration. If the aim of neurophysiological monitoring is to "detect and protect", it may not be limited to detecting seizures, rather it should be able to identify brain deterioration, so we propose the combined monitoring of EEG with SEP.
