International research has demonstrated disparities in the Emergency Department care of patients of certain racial or ethnic backgrounds. The management of minor head injuries requires a careful clinical assessment to determine the requirement of a CT scan of the head. The aim of this study was to determine if there was any disparity, based on race, in the management of minor head injury. ⋯ This study concluded that there was no statistically significant disparity based upon race in the management of minor head injuries with regard to decision to perform a CT head scan. There is some evidence that indigenous patients waited longer to be seen. A multi-centre prospective study is necessary to confirm these findings.

Electrolyte values are measured both by arterial blood gas (ABG) analyzers and central laboratory auto-analyzers (AA), but a significant time gap exists between the availability of both these results, with the ABG giving faster results than the AA. The authors hypothesized that there is no difference between the results obtained after measurement of electrolytes by the blood gas and auto-analyzers. ⋯ Based on the above analysis, the authors found no significant difference between the potassium values measured by the blood gas machine and the auto-analyzer. However, the difference between the measured sodium was found to be significant. We therefore conclude that critical decisions can be made by trusting the potassium values obtained from the arterial blood gas analysis.

The purpose of this study was to evaluate the effectiveness of a new, fixed, yet individualized dosing regimen of activated prothrombin complex concentrate factor VIII inhibitor bypassing activity (FEIBA) for warfarin reversal in the setting of a life-threatening bleeding in a secondary care center. ⋯ The presented dosing regimen results in safe reversal of warfarin-induced coagulopathy, which appears to be faster and more profound than following FFP. Moreover, the use of activated PCC (FEIBA) does not appear to carry an increased risk of thrombotic events when compared to the rate reported for several non-activated PCC preparations.

Vascular access is a critical skill for emergency physicians. However, it can be unpredictably challenging in some patients. While ultrasound-guided vascular access has been encouraged in emergency departments, there have been few studies evaluating echo-enhanced needles and their usefulness in performing vascular access. ⋯ Echo-enhanced needles did not provide objective performance improvement compared to standard needles during ultrasound-guided vascular access with a vascular access model in the short axis.

There are no general policies or protocols for procedural sedation in the emergency department and no literature on present practice in South Africa. ⋯ The private sector is generally better serviced for PS than the public sector. Most ED clinicians use morphine and midazolam for PS. However, there is widespread awareness of propofol as an alternative and probably superior PS drug. Recommendations for improving PS include development of general protocols for PS, training of doctors at all levels and optimization of ED facilities and staffing.
