Children, term and preterm newborn care require electrophysiologic investigations for seizure detection and therapeutic management or prognosis purposes. Amplitude-integrated electroencephalography (aEEG) offers an accessible by non expert, bedside continuous cerebral monitoring. A 2 year utilization of aEEG in a neonatal and paediatric intensive care unit is described as advantages and as pitfalls. Technical description and aEEG classifications for interpretation only available for term newborn are described. To obtain a performing utilization (technical and interpretation) it was necessary to have about 1 year of training including medical and paramedical formations. Our experience shows that this easy-to-use technique requires a careful management, a trained and vigilant staff notably electrophysiologist to avoid inappropriate conclusions. Finally, aEEG is very efficient but in complement of standard EEG.
