[Management of neonatal seizures].
The aim of this review is to focus on the nosological classification of neonatal "convulsions", to precise the underlying aetiologies and the prognosis, and to propose diagnostic and therapeutical approach. Seizures may be epileptic or not, they may be occasional, part of an epilepsy syndrome or associated to a metabolic disease. Electroencephalography plays a central role; it enables to confirm the epileptic nature of the ictal events, it allows to evaluate the prognosis and to guide the treatment decision, and sometimes may help in the etiological diagnosis. Work up should include cerebral imaging (MRI) completed by other exams according to the diagnostic hypothesis. It is essential to go as far as possible in the etiological work-up not to attribute convulsions to an occasional event as HIE in which criteria remain very strict, when convulsions could be due to genetic origin or to maternal pathology. Treatment decision should comprise different ways: treatment of the underlying cause, of the eventual associated pathologies, maintenance of vital functions and antiepileptic treatment. Phenobarbitone remains the first line drug in occasional seizures, and second line drugs for which further studies are needed both for immediate and long-term secondary effects. Besides occasional seizures epilepsy syndromes and metabolic diseases remain exceptional. Nevertheless recognition of these conditions allows to establish the prognosis and to start immediately with an appropriate and specific medication depending on the epilepsy syndrome and can contribute to a prenatal diagnosis. It is important to recognize the inborn errors of metabolism because emergency appropriate treatment is required. Prognosis which is generally bad is essentially related to the underlying aetiology and probably to the duration of the active period of seizures.
