Training approaches and devices utilization during endotracheal intubation in French Emergency Departments: a nationwide survey.

BACKGROUND AND IMPORTANCE: Endotracheal intubation is a lifesaving procedure that is reportedly associated to a significant risk of adverse events. Recent trials have reported that the use of videolaryngoscope and of a stylet might limit this risk during emergency intubation. OBJECTIVES: The objective of this study was to provide a national description of intubation practices in French Emergency Departments (EDs). SETTINGS AND PARTICIPANTS: We conducted an online nationwide survey by sending an anonymous 37-item questionnaire via e-mail to 629 physicians in French EDs between 2020 and 2022. INTERVENTION: A single questionnaire was sent to a sole referent physician in each ED. OUTCOME MEASURES AND ANALYSIS: The primary endpoint was to assess the proportion of French EDs in which videolaryngoscopy was available for emergency intubation and its use in routine practice. Secondary endpoints included the presence of local protocol or standard of procedure for intubation, availability of capnography, and routine use of a stylet. MAIN RESULTS: Of the surveyed EDs, 342 (54.4%) returned the completed questionnaire. A videolaryngoscope was available in 193 (56%) EDs, and direct laryngoscopy without a stylet was majorly used as the primary approach in 280 (82%) EDs. Among the participating EDs, 74% had an established protocol for intubation and 92% provided a capnography device for routine verification of tube position. In cases of difficult intubation, the use of a bougie was recommended in 227 (81%) EDs, and a switch to a videolaryngoscope in 16 (6%) EDs. The most frequently used videolaryngoscope models were McGrath Mac Airtraq (51%), followed by Airtraq (41%), and Glidescope (14%). CONCLUSION: In this large French survey, the majority of EDs recommended direct laryngoscopy without stylet, with seldom use of videolaryngoscopy.

[Anaphylaxis and pathophysiology]. / Physiopathologie de l'anaphylaxie.

Anaphylaxis is the most severe of the allergic hypersensitivity reactions. It is caused by the release of mediators from blood components such as mast cells and basophils into the bloodstream. Anaphylaxis is a common disease, its diagnosis is clinical and, given its pathophysiology, the treatment of choice is adrenaline.
