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.
