    ABSTRACT: To study any change in reference accuracy in the Australasian emergency medicine journal (now known as Emergency Medicine Australasia), in the 10 years since a previous analysis was undertaken. A sample of 100 randomly selected references was compared with the results from the previous analysis. There was a significant reduction in the number of citations with errors and in the total number of errors. This paper demonstrates a significant improvement in the accuracy of references in the journal Emergency Medicine Australasia over the past decade. This paper did not identify the reasons for this improvement, but potential causes might include the introduction of a web-based peer review and manuscript submission process, as well as improved reference bibliography systems by authors. In addition, an increase in the overall standard of paper submitted to the journal might have contributed to this improvement.

    ABSTRACT: Haemodynamic targets, such as cardiac output, mean arterial blood pressure and central venous oxygen saturations, remain crude predictors of tissue perfusion and oxygen supply at a cellular level. Shocked patients may appear adequately resuscitated based on normalization of global vital signs, yet they are still experiencing occult hypoperfusion. If targeted resuscitation is employed, appropriate use of end-points is critical. In this review, we consider the value of directing resuscitation at the microcirculation or cellular level. Current technologies available include sublingual capnometry, video microscopy of the microcirculation and near-infrared spectroscopy providing a measure of tissue oxygenation, whereas base deficit and lactate potentially provide a surrogate measure of the adequacy of global perfusion. The methodology and evidence for these technologies guiding resuscitation are considered in this narrative review.

    ABSTRACT: The use of appropriate resuscitation targets or end-points may facilitate early detection and appropriate management of shock. There is a fine balance between oxygen delivery and consumption, and when this is perturbed, an oxygen debt is generated. In this narrative review, we explore the value of global haemodynamic resuscitation end-points, including pulse rate, blood pressure, central venous pressure and mixed/central venous oxygen saturations. The evidence supporting the reliability of these parameters as end-points for guiding resuscitation and their potential limitations are evaluated.

    ABSTRACT: In 2006, the American Board of Emergency Medicine co-sponsored hospice and palliative medicine as a recognized medical subspecialty. There is recognition of the need for these skills to be available in EDs in the USA. This article discusses the rationale for integrating a palliative approach in the ED. We need to engage our palliative care colleagues to increase clinical support to meet the needs of these vulnerable patients and to foster collaborative educational opportunities.

    ABSTRACT: The objective of the present study was to determine the prevalence of exercise-associated hyponatraemia in hikers/trekkers along the Kokoda Trail. This was a cross-sectional study of 191 trekkers on the Kokoda Trail, Papua New Guinea. Blood was taken and analysed immediately using point-of-care technology 2 days walk from each end of the Trail. The main outcome measure was hyponatraemia defined as serum sodium level less than 135 mmol/L. Three participants (1.6%, 95% CI 0.5-4.5%) were found to have mild hyponatraemia. The hyponatraemic group had a median estimated fluid intake on the day of testing that was almost double that of the normal sodium group (6 L vs 3.3 L). Exercise-associated hyponatraemia occurs in trekkers on the Kokoda Trail. Strategies for prevention of exercise-associated hyponatraemia should be delivered to trekkers via the trekking companies, chiefly focussing on only drinking in response to thirst.

    ABSTRACT: Debate around medical futility has produced a vast literature that continues to grow. Largely absent from the broader literature is the role of emergency medicine in either starting measures that prove to be futile, withholding treatment or starting the end of life communication process with patients and families. In this discussion we review the status of the futility debate in general, identify some of the perceived barriers in managing futile care in the ED including the ethical and legal issues, and establish the contribution of emergency medicine in this important debate. We conclude that emergency physicians have the clinical ability and the legal and moral standing to resist providing futile treatment. In these situations they can take a different path that focuses on comfort care thereby initiating the process of the much sought after 'good death'.
