RESUMO
Incidents involving ionizing radiation pose a risk of immediate and long-term clinical consequences for both victims and responders in the event of secondary contamination. Rapid identification of the problem and a coordinated response are crucial. This article summarizes the key challenges related to the emergency management of a single patient or multiple victims, addressing the importance of recognizing such a case, radioprotection measures, decontamination, and available treatments.
Les incidents impliquant des rayonnements ionisants représentent un risque aux conséquences cliniques immédiates et à long terme, tant pour les victimes que pour les intervenants en cas de contamination secondaire. L'identification rapide de la problématique et une réponse coordonnée sont cruciales. Cet article résume les principaux enjeux liés à la prise en charge en urgence d'un patient unique ou de plusieurs victimes, en abordant l'importance de la reconnaissance d'un tel cas, des mesures de radioprotection, de la décontamination et des traitements disponibles.

Research in prehospital and in-hospital emergency medicine is essential to the development of this discipline. By calling certain practices into question (thrombolysis for minor strokes, use of coagulation factors for patients with severe polytrauma), providing access to new technologies (video-laryngoscopy, POCT troponins in pre-hospital care) or questioning new practices (double defibrillation, pulmonary US in pneumonia), research enables emergency physicians to adapt their day-to-day practice.
La recherche en médecine d'urgence, tant sur le plan préhospitalier qu'hospitalier, est nécessaire et même indispensable à la fois au développement de cette discipline, mais également à la reconnaissance de ses spécificités. Par la remise en question de certaines pratiques (thrombolyse pour les AVC mineurs, utilisation de facteurs de la coagulation pour le polytraumatisé sévère), l'accès à de nouvelles technologies (vidéo-laryngoscopie, troponines POCT en préhospitalier) ou le questionnement sur de nouvelles pratiques (double défibrillation, US pulmonaire dans la pneumonie), la recherche permet aux urgentistes d'adapter leur pratique quotidienne à l'état de l'art.

INTRODUCTION: Acute respiratory failure is a life-threatening condition frequently found in the emergency department. High-flow nasal oxygen (HFNO) is increasingly used in emergency departments for patients with hypoxaemic acute respiratory failure. However, despite the increasing number of studies, its potential advantages regarding the need for therapeutic escalation and mortality have not been precisely evaluated. Our objective is to compare conventional oxygen therapy to HFNO when they are initiated during the first hour following the patient's arrival at the emergency department, with the hypothesis that HFNO would reduce the need for ventilatory therapy escalation. METHODS AND ANALYSIS: This is a multicentric, prospective, open and randomised superiority study. 500 inpatients will be randomised (1:1) to receive conventional oxygen therapy or HNFO. The primary outcome is a failure in the oxygen therapy defined as the need for a therapeutic escalation within 4 hours after therapy initiation. ETHICS AND DISSEMINATION: The study has been submitted and approved by the Comité de Protection des Personnes Nord Ouest IV (20 October 2020). As required, a notification was sent to the Agence nationale de sécurité du médicament et des produits de santé (22 October 2020). The research results will be published in peer-reviewed publications and presented at international conferences. TRIAL REGISTRATION NUMBER: NCT04607967.
