Multicenter Study Observational Study
Accuracy of NEXUS II head injury decision rule in children: a prospective PREDICT cohort study.
The National Emergency X-Radiography Utilisation Study II (NEXUS II) clinical decision rule (CDR) can be used to optimise the use of CT in children with head trauma. We set out to externally validate this CDR in a large cohort. ⋯ NEXUS II had high sensitivity, similar to the derivation study. However, approximately half of unimaged patients were positive for NEXUS II risk criteria; this may result in an increased CT rate in a setting with high clinician accuracy.

We previously reported that benzodiazepine detoxification for alcohol withdrawal using symptom-triggered therapy (STT) with oral diazepam reduced length of stay (LOS) and cumulative benzodiazepine dose by comparison with standard fixed-dose regimen. In this study, we aim to describe the feasibility of STT in an emergency department (ED) short-stay clinical decision unit (CDU) setting. ⋯ STT is potentially feasible as a rapid and effective approach to managing alcohol withdrawal syndrome in the ED/CDU short-stay inpatient setting where patient LOS is generally less than 24 hours.

The number of EDs visit is on the increase, and the pressure on EDs is of significant concern worldwide. The usage of EDs by parents of children with minor illness is an important and still unresolved problem causing a burden to healthcare services. The aim of this study was to review the literature to summarise parental reasons for visiting ED for children with minor illness. ⋯ This review identified some of the reasons why parents bring their children to the ED for minor illnesses highlighting the multifaceted nature of this problem. Understanding parental reasons behind their choice to use the ED may help us better design targeted interventions to reduce unnecessary ED visits and alleviate the burden on overstretched healthcare services. This review may help inform emergency care policy makers, researchers and healthcare staff to understand parents' reasons for visiting the ED, to better meet their healthcare needs.

Observational Study
Near-infrared spectroscopy monitoring during out-of-hospital cardiac arrest: can the initial cerebral tissue oxygenation index predict ROSC?
Near-infrared spectroscopy is a modality that can monitor tissue oxygenation index (TOI) and has potential to evaluate return of spontaneous circulation (ROSC) during cardiopulmonary resuscitation (CPR). This study's objectives were to evaluate whether TOI could be associated with ROSC and used to help guide the decision to either terminate CPR or proceed to extracorporeal CPR (ECPR). ⋯ This study demonstrated an association between higher initial TOI and ROSC. Initial TOI could increase the accuracy of ROSC prognosis and may be a clinical factor in the decision to terminate CPR and select patients who are to proceed to ECPR.

Randomized Controlled Trial
Testing of a novel Valsalva Assist Device with supine and modified positions in healthy volunteers.
The Valsalva manoeuvre (VM) is used to treat supraventricular tachycardia (SVT) by inducing a vagal response (drop in HR). There is debate as to the best position in which to carry out the VM and how the strain should be delivered in practice. We aimed to compare vagal responses induced with supine and modified VMs using strains delivered with a standardised manometer or novel Valsalva Assist Device (VAD), a simple device to provide resistance to exhalation. ⋯ Modified VM was associated with a greater drop in HR than a supine VM with no increase in adverse events in healthy volunteers. The VAD can be used to safely generate the recommended VM strain pressure, but produced a smaller drop in HR compared with a manometer and requires modification to enable the recommended strain duration to be achieved consistently.
