Nausea and vomiting is a common ED chief complaint. However, randomised trials comparing antiemetic agents to placebo have not demonstrated superiority. This systematic review investigates the efficacy of inhaled isopropyl alcohol (IPA) compared with usual care or placebo in adults presenting to the ED with nausea and vomiting. ⋯ CRD42022299815.

Transcutaneous carbon dioxide (Ptcco2) measurement is a non-invasive surrogate marker for arterial carbon dioxide (Paco2), which requires invasive arterial blood sampling. Use of Ptcco2 has been examined in different clinical settings, however, most existing evidence in the adult emergency department (ED) setting shows insufficient agreement between the measurements. This study assessed the level of agreement between Ptcco2 and Paco2 in undifferentiated adult ED patients across multiple timepoints. ⋯ The level of agreement between Ptcco2 and Paco2 measurements may not be sufficiently precise for the adoption of Ptcco2 monitoring in patients presenting to the ED.

Uncertainty is particularly obvious in emergency medicine (EM) due to the characteristics of the patient cohort, time constraints, and busy environment. Periods of transition are thought to add to uncertainty. Managing uncertainty is recognised as a key ability for medical practice, but is often not addressed explicitly. This study explored how new consultants in EM experience uncertainty, with the aim of making explicit what is often hidden and potentially informing support for doctors to manage the uncertainty they face. ⋯ This study highlights the need for new consultants to have psychologically safe, reflective spaces to think through uncertainties with others. This appears to reduce uncertainty, and also act as a source of feedback. The study adds to the existing calls to address uncertainty more explicitly in training, and challenge the expectations of certainty that exist within medicine.

Combined ED and police department (PD) data have improved violence surveillance in the UK, enabling significantly improved prevention. We sought to determine if the addition of emergency medical service (EMS) data to ED data would contribute meaningful information on violence-related paediatric injuries beyond PD record data in a US city. ⋯ Many violence locations in ED and EMS data were not present in PD records. A combined PD, ED and EMS database resulted in new knowledge of the geospatial distribution of violence-related paediatric injuries and can be used for data-informed and targeted prevention of violence in which children are injured-especially in and around schools and parks.

Mild traumatic brain injury is a common presentation to the emergency department, with current management often focusing on determining whether a patient requires a CT head scan and/or neurosurgical intervention. There is a growing appreciation that approximately 20%-40% of patients, including those with a negative (normal) CT, will develop ongoing symptoms for months to years, often termed post-concussion syndrome. Owing to the requirement for improved diagnostic and prognostic mechanisms, there has been increasing evidence concerning the utility of both imaging and blood biomarkers. ⋯ MRI, using clinical sequences and advanced quantitative methods, can detect lesions not visible on CT in up to 30% of patients that may explain, at least in part, some of the ongoing problems. The ability of an acute biomarker (be it imaging, blood or other) to highlight those patients at greater risk of ongoing deficits would allow for greater personalisation of follow-up care and resource allocation. We discuss here both the current evidence and the future potential clinical usage of blood biomarkers and advanced MRI to improve diagnostic pathways and outcome prediction following mild traumatic brain injury.
