People with autism spectrum disorder visit emergency departments more frequently than the rest of the population. Their ability to communicate with their environment may not only be limited but also different from the interactions of non-autistic people. In addition, the multiple sensory stimulations present in the emergency departments are likely...

Aims: The main objective of this study was to describe patients who were involuntarily admitted to the emergency department of Lausanne University Hospital on involuntary admission in 2018 in terms of age, gender, emergency department length of stay, the motive for involuntary admission, use of psychoactive substances, diagnosis, and destination a...

Acute agitation is a frequent cause of emergency department’s consultation. Managing an agitated patient is complex due to many factors and require from healthcare teams a close interdisciplinary collaboration. Scope of this article is to describe the management of agitated patients in an emergency department and to present an interprofessional med...

Objective We aimed to assess if emergency department (ED) syndromic surveillance during the first and second waves of the COVID-19 outbreak could have improved our surveillance system. Design and settings We did an observational study using aggregated data from the ED of a university hospital and public health authorities in western Switzerland....

Background: Basic life support (BLS) is the first link in the chain of survival and should be performed by every lay rescuer. Although international studies have suggested that BLS knowledge was poor among the overall population, Swiss data are scarce. Our objective in this study was to evaluate BLS knowledge among Swiss conscripts, a semi-represe...

Background. Workplace violence is a serious and increasing problem in health care. Nevertheless, only few studies were carried out concerning this topic and then mainly in English-speaking countries. The objectives were to describe the acts of violence experienced by prehospital emergency care providers (PECPs) in the western part of Switzerland be...

With great interest, we have read the review article of Simpson et al. on the current evidence and recommendations for the pre-hospital management of penetrating neck injuries (PNI). We would like to comment on the use of Foley catheters to achieve bleeding control from non-compressible penetrating injuries. In their scoping review, the authors app...

Alerting emergency medical services, rapidly initiating chest compressions at the correct depth and frequency and delivering an electric shock as quickly as possible remain the key points of the updated guidelines for adult cardiopulmonary resuscitation (CPR). Following their five-year systematic review, both the American Heart Association (AHA) an...

Abstract Background Noninvasive ventilation (NIV) is recognized as first line ventilatory support for the management of acute pulmonary edema (APE) and chronic obstructive pulmonary disease (COPD) exacerbations. We aimed to study the prehospital management of patients in acute respiratory distress with an indication for NIV and whether they receive...

Smartphones and connected devices allow patients to monitor their health in a variety of ways. We report the case of a patient presenting to the emergency department complaining of palpitations and syncope. Standard investigations were unremarkable. However, an electrocardiogram recorded through his Apple Watch® indicated ventricular tachycardia. T...

The physiological changes in the pregnant woman expose her to a risk of faster respiratory decompensation. Asthma affects 2-13% of pregnancies. It is therefore important to ensure regular monitoring to allow good control of asthma to reduce the risk of exacerbations. Finally, the background treatment, such as exacerbations, must be identical to the...

Study objective: We aimed to clarify the definition, epidemiology, and pathophysiology of excited delirium syndrome (ExDS) and to summarize evidence-based treatment recommendations. Methods: We conducted a systematic literature search of MEDLINE, Ovid, Web of Knowledge, and Cochrane Library for articles published to March 18, 2017. We also searc...

Many of our medical procedures are conditioned by beliefs or experiences by our mentors, which we pass on to the younger, for example: gradually emptying a full bladder to avoid hypotension or haemorrhage, hydrating the alcoholic so that the blood alcohol level decreases faster, always obtaining an arterial blood gas instead of a venous one and not...

The objective is to describe the characteristics of mechanically restrained patients in the emergency department (ED) of a university hospital and to evaluate the quality of restraint documentation that was filled out according to the dedicated protocol with respect to the law on restraint. All adult patients (≥16 years) who were admitted to the ED...

The morbidity and mortality of the 2014–2015 influenza season were more important than those in previous years. We assessed the impact of the 2014–2015 influenza season on the length of stay (LOS) and workload in an academic emergency department (ED). This is a monocentric retrospective study. The database of the microbiology laboratory was used to...

Several articles have been published during 2016 suggesting amendments in certain established practices of emergency medicine. Amongst such practices now in question are : 1) the use in mechanical cardiopulmonary resuscitation of amiodarone and lidocaine which appear not to improve survival or neurological outcome ; 2) apneic oxygenation being asso...

Purpose: Obstructive sleep apnea syndrome (OSA) increases the risk of cardiovascular disease.We aimed at evaluating the effect of continuous positive airway pressure (CPAP) treatment on coronary endothelium-dependent vasoreactivity in OSA patients by quantifying myocardial blood flow (MBF) response to cold pressure testing (CPT). Methods: In the mo...

The year 2015 was marked by several publications questioning the practice of emergency medicine. The systematic administration of oxygen in STEMI patients offers no benefit. Similarly, medical expulsive therapy in patients with ureteric stones was questioned. Administration of steroids for acute radiculopathy showed only short-term, but no mid-term...
