ReviewReview article: Ventricular assist devices in the emergency department.
Ventricular assist devices (VADs) have become an indispensable tool in the management of end-stage cardiac failure, both as a means of bridging to cardiac transplantation and as destination therapy for long-term quality of life improvement. Although the technology continues to advance and these devices continue to be refined, they are still associated with significant complications. This article reviews the basics of VAD function and physiology, as well as the myriad to complications that follow their implantation. This review aims to provide a systematic approach to the troubleshooting, diagnosis and management of both VAD-associated complications and the resuscitation of the decompensated VAD patient presenting to the ED.

A stream for complex, ambulant patients reduces crowding in an emergency department.
The study aims to evaluate the effect of adding a stream for complex, ambulatory patients in an ED. ⋯ The use of an appropriately resourced stream directed towards seeing a complex group of patients who do not require ongoing nursing care and who are capable of sitting in a chair improved departmental flow.

Limited utility of exercise stress testing in the evaluation of suspected acute coronary syndrome in patients aged less than 40 years with intermediate risk features.
National guidelines for management of intermediate risk patients with suspected acute coronary syndrome, in whom AMI has been excluded, advocate provocative testing to final risk stratify these patients into low risk (negative testing) or high risk (positive testing suggestive of unstable angina). Adults less than 40 years have a low pretest probability of acute coronary syndrome. The utility of exercise stress testing in young adults with chest pain suspected of acute coronary syndrome who have National Heart Foundation intermediate risk features was evaluated. ⋯ Routine exercise stress testing has limited value in the risk stratification of adults less than 40 years with suspected intermediate risk of acute coronary syndrome.

Paracetamol toxicity: What would be the implications of a change in Australian treatment guidelines?
The present study aims to study the implications for resource utilisation if Australia adopted recent revised UK treatment guidelines for paracetamol poisoning. ⋯ Alignment of current Australian paracetamol treatment guidelines with those in the UK would result in an increase in ED attendances as directed by Poisons Information Centres and hospital admissions for antidotal treatment. This would be associated with increased health expenditure and inpatient bed utilisation. The present study does not support the clinical need for adoption of UK paracetamol treatment guidelines in Australia.

Following findings of the Clinical Randomisation of an Antifibrinolytic in Significant Haemorrhage (CRASH-2) trial, tranexamic acid (TxA) use post trauma is becoming widespread. However, issues of generalisability, applicability and predictability beyond the context of study sites remain unresolved. ⋯ The study population chosen has high mortality and morbidity and is potentially most likely to benefit from TxA's known mechanisms of action. This and further trials involving appropriate sample populations are required before evidence based guidelines on TxA use during trauma resuscitation can be developed.
