Observational Study
Point-of-care ultrasonography for the management of shoulder dislocation in ED.
Point-of-care ultrasonography (POCUS) is an easily available and noninvasive tool without radiation exposure that is also gaining a broad range of use in emergency departments. The aim of this study is to evaluate the value of POCUS in the diagnosis of shoulder dislocation by comparing with plain radiography. ⋯ Point-of-care ultrasonography is an effective tool to either rule in or rule out shoulder dislocation in the emergency setting. Furthermore, it is a robust sensitive tool for excluding fractures but with false-positive results.

Meta Analysis Comparative Study
Effects of long axis in-plane vs short axis out-of-plane techniques during ultrasound-guided vascular access: preliminary evidence.
Currently, whether long-axis in-plane (LA-IP) is superior to short-axis out-of-plane (SA-OOP) during ultrasound-guided vascular access remains inconclusive. We, therefore, conducted a meta-analysis of randomized controlled trials to compare the effects of LA-IP vs SA-OOP techniques in patients undergoing ultrasound-guided vascular access (USGVA). ⋯ There is insufficient evidence to definitively choose either LA-IP or SA-OOP in patients undergoing USGVA. Further robustly well-designed trials are warranted to investigate the appropriate technique in patients receiving USGVA.

Randomized Controlled Trial
Topical ethyl chloride to reduce pain associated with venous catheterization: a randomized crossover trial.
To compare pain associated with venous catheterization after administration of topical ethyl chloride vs placebo among emergency department health care providers. ⋯ We found that topical ethyl chloride yields a greater reduction in pain associated with venous catheterization compared with topical placebo.

Randomized Controlled Trial
The effect of nebulized magnesium sulfate in the treatment of moderate to severe asthma attacks: a randomized clinical trial.
Thirty percent of people with asthma do not respond to standard treatment, and complementary therapies are needed. The objective of this study was to investigate the impact of inhaled magnesium sulfate on the treatment response in emergency department (ED) patients with moderate to severe attacks of asthma. ⋯ Adding nebulized magnesium sulfate to standard therapy in patients with moderate to severe asthma attacks leads to greater and faster improvement in PEFR, respiratory rate, oxygen saturation and respiratory rate. It also reduces hospitalization rates in this patient population.
