Dyspnoea is the most common sign of heart failure (HF). Patients accessing the ED for HF-related symptoms require fast diagnosis and early treatment. Transthoracic echocardiography has a crucial role in HF diagnosis, but requires qualified staff and adequate time for execution. The measurement of inferior vena cava (IVC) diameter has been recently proposed as a rapid, simple and reliable marker of volume overload. The aim of this systematic review was to assess the accuracy of IVC-ultrasound as a stand-alone test for HF diagnosis in patients presenting to the ED with acute dyspnoea. ⋯ Our findings suggest that the sensitivity and specificity of IVC-CIx are suboptimal to rule in or rule out HF diagnosis in patients with acute dyspnoea in the ED setting. Therefore, IVC-CIx is not advisable as a stand-alone test, but may be useful when integrated in a specific diagnostic algorithm for the differential diagnosis of acute dyspnoea.

Personal protective equipment (PPE) used by healthcare workers was scarce during the COVID-19 pandemic. The aim of this study was to assess whether telemedicine (using iPads) reduced PPE use in emergency department (ED) patients who were treated in contact isolation, and whether telemedicine had a positive effect on patient anxiety and satisfaction. ⋯ PPE use by physicians can successfully be reduced by using telemedicine in the ED without increasing anxiety or dissatisfaction. This study was a first step to gain experience with telemedicine in the ED which has the potential to reduce PPE use in future pandemics or other patients with an indication for contact isolation.

Multicenter Study
Propofol Target-Controlled Infusion in Emergency Department Sedation (ProTEDS): a multicentre, single-arm feasibility study.
Procedural sedation is a core skill of the emergency physician. Bolus administration of propofol is widely used in UK EDs. Titrated to an end point of sedation, it has a rapid effect but has been associated with adverse incidents. The use of a target-controlled infusion (TCI) of propofol is not routine but may reduce the incidence of adverse incidents.The primary aims of this single-arm feasibility study were patient satisfaction and to establish recruitment rates for a randomised controlled trial comparing propofol TCI to bolus administration. ⋯ Propofol TCI was acceptable as a method of procedural sedation for patients. The lower than expected recruitment rates highlight the need for dedicated research support.

Observational Study
Characteristics, physiology and mortality of intubated patients in an emergency care population in sub-Saharan Africa: a prospective cohort study from Kigali, Rwanda.
Formalised emergency departments (ED) are in early development in sub-Saharan Africa and there are limited data on emergency airway management in those settings. This study evaluates characteristics and outcomes of ED endotracheal intubation, as well as risk factors for mortality, at a teaching hospital in Rwanda. ⋯ The first-attempt and overall success rates for intubation in this ED in Rwanda were comparable to those in high-income countries (HIC). Mortality postintubation is associated with lower postintubation SBP and higher postintubation shock index. The high complication and mortality rates suggest the need for better resources and training to address differences in compared with HIC.
