Controlled oxygen therapy at emergency department presentation increases the likelihood of achieving target oxygen saturations in patients with exacerbations of chronic obstructive pulmonary disease.
This study aimed to determine whether initiation of controlled oxygen therapy at ED presentation increased the proportion of patients with chronic obstructive pulmonary disease (COPD) achieving the COPD-X guideline target SpO2 range (88-92%) at 30 min and if it impacted total hospital length of stay or in-hospital mortality. ⋯ Patients with exacerbations of COPD receiving controlled oxygen therapy were more likely to achieve SpO2 within the COPD-X guideline target range without being more likely to be hypoxic. The proportion of patients with SpO2 within the target range was low, suggesting that further work on processes to optimise oxygenation in this group of patients is needed.

Predictors for urologic intervention and alternate diagnoses in people having computed tomography urography for suspected renal colic.
The majority of ureteric calculi pass spontaneously and are uncomplicated, yet use of computed tomography urography (CTU) has increased in recent years. This study describes a cohort of ED patients undergoing CTU for renal colic and assesses the predictors of urologic intervention. ⋯ Factors associated with urologic intervention included female sex, single kidney, calculus size >5 mm and proximal calculus. Information on acute alternate diagnoses was uncommon. A prospective study is needed to further clarify clinical parameters that could predict intervention to allow targeting of CTU to those most likely to benefit.

Current profile of cycling injuries: A retrospective analysis of a trauma centre level 1 in Queensland.
One out of 50 injury-related presentations to an ED is a transport-related cycling injury. Detailed information about the most frequent mechanism of cycling injuries, sustained injuries and patterns are under-reported. The objective of this research was to examine the pattern of injuries sustained by cyclists at a level 1 trauma centre. ⋯ This current data review reveals that non-collision traffic crashes accounted for the majority of injuries in cyclists treated in this facility, and the upper limb has replaced the head as the most injured body part. With a growing number of cyclists, this information contributes to considerations to improve road safety and trauma management.

Ventilator-assisted preoxygenation: Protocol for combining non-invasive ventilation and apnoeic oxygenation using a portable ventilator.
To describe a simple protocol for ventilator-assisted preoxygenation (VAPOX) prior to rapid sequence intubation in the ED using a Hamilton T1 ventilator in an effort to further reduce the incidence of transient and critical hypoxaemia. ⋯ Preoxygenation using a ventilator with an open valve system may allow safe combination of non-invasive ventilation, pressure controlled ventilation and apnoeic oxygenation using nasal cannula. VAPOX may be the technique of choice to preoxygenate and apnoeic oxygenate many patients who undergo rapid sequence intubation in the ED equipped with these ventilators.
