Adults with Irritants (household sprays, paint fumes) asthma, including those with onset during adulthood, rarely become permanently asymptomatic.

Pulse oxymetry (and if possible arterial blood gaze) should be use to detect early signs of hypoxia and acidosis, either of which if significant required emergency intervention to terminate the seizure. Therefore, medication compliance should always be emphasized to every (epileptic) patient. For epileptic patient, family must aware of danger from patient driving capability. Particular patients • In patients who experience a solitary seizure, or several briefs seizures with known precipitant, long term anticonvulsants are not always necessary. Depend on drug pharmacokinetic, drug for rapid seizure control and drug for maintaining the control should be co-administered (eg. With certain agents, symptoms may not develop for days or even weeks after cessation of use. Common practice is to consider a prophylactic loading dose of an antiepileptic medication (typically phenytoin or fosphenytoin). Most of new onset is causes by reversible disorders, the symptoms may not reoccur, however, some brain injury, brain abscess, or meningitis may lead to a chronic problem (epilepsy). Most of new onset seizures do not need drug for stopping convulsion, some need drug for stopping and drugs for preventing convulsion, and among these patients a few need a long course treatment.

Tous les intoxiqués symptomatiques doit être surveillés dans le service d’urgence, Il faut faire l’attention à l’hypotonie musculaire et l’arrêt respiratoire qui peut survenir subitement, souvent précédé par l’hypotonie des muscles du cou. Objectif du traitement • Maintenir les fonctions vitales • Diminue l’absorption de la substance • Neutraliser les effets toxiques • Renforcement l’élimination des toxiques • Prévenir la rechute 2. Anamnèse, pour avoir la notion de produit toxique, circonstance de la prise, la dose administrée, l’horaire de la prise et les signes et symptômes de début. Pour la contamination par voie cutanée il faut faire la décontamination dermique par lavage abondant (après déshabillé) avec du savon doux. Il faut prévenir la contamination secondaire par contact direct avec les habits et la surface cutanée contaminés. Pour les yeux on fait avec du sérum physiologique La décontamination digestive (lavage gastrique). Pour l’intoxication par la voie digestive, le lavage gastrique est indiqué, suivit par l’administration de charbon actif.
