Les réactions allergiques constituent une cause fréquente d’admission aux Urgences. L’anaphylaxie en est la classe la plus sévère, pouvant être stadifiée en fonction de sa sévérité et de son atteinte des différents organes. Elle résulte principalement de la décharge dans l’organisme de médiateurs chimiques secondaire à l’exposition à un allergène. Le traitement doit être instauré sans délai pour obtenir un résultat optimal. Il comprend principalement l’administration d’adrénaline intra-musculaire (IM) et de bêta2-mimétiques inhalés. En cas d’hypotension, des cristalloïdes intra-veineux (IV) seront perfusés. Selon les recommandations récentes, les autres traitements ne sont pas appropriés dans l’approche initial de la phase aiguë. Le type et la durée de la surveillance seront adaptés au niveau de gravité de la réaction anaphylactique. Un suivi spécialisé en allergologie devra être initié et une prescription d’adrénaline auto-injectable devra être remise au patient à sa sortie de l’hôpital.
Allergic reactions are a common cause of emergency department admissions. The most serious class is anaphylaxis, which can be graded according to its severity and its impact on different organs. It is primarily caused by the release of various chemical mediators into the body following contact with an allergen. Treatment must be initiated as quickly as possible to achieve a satisfactory outcome. It mainly consists of intramuscular (IM) epinephrine and inhalated beta2-agonists. Some intravenous (IV) crystalloids may be given in case of hypotension. According to the latest guidelines, other treatments are not appropriate in the initial approach of the acute phase. Close monitoring should be carried out depending on the initial severity of the anaphylactic reaction. Specialized follow-up in allergology should be initiated, and a prescription for an epinephrine auto-injector should be given to the patient discharged from hospital.
