Review Comparative Study
Intraarticular lidocaine versus intravenous procedural sedation with narcotics and benzodiazepines for reduction of the dislocated shoulder: a systematic review.
Anterior shoulder dislocations commonly present to the emergency department (ED). The time associated with procedural sedation for the reduction of anterior shoulder dislocations can be lengthy and may require use of additional personnel. Complications associated with intravenous (IV) medications for procedural sedation are well documented. ⋯ The use of IAL for reduction of anterior shoulder dislocations should be strongly considered as a first line therapy because it is effective and safe and may potentially reduce time spent in the ED.

Multicenter Study
Availability and quality of computed tomography and magnetic resonance imaging equipment in U.S. emergency departments.
The objective was to determine the availability and quality of computed tomography (CT) and magnetic resonance imaging (MRI) equipment in U.S. emergency departments (EDs). The authors hypothesized that smaller, rural EDs have less availability and lower-quality equipment. ⋯ Although access to CT imaging was high (>90%), CT resolution and access to MRI were variable. Based on observed differences, the availability and quality of imaging equipment may vary by ED size and location.

Randomized Controlled Trial
Success of ultrasound-guided peripheral intravenous access with skin marking.
The most effective technique for ultrasound-guided peripheral intravenous access (USGPIVA) is unknown. In the traditional short-axis technique (locate, align, puncture [LAP]), the target vessel is aligned in short axis with the center of the transducer. The needle is then directed toward the target under real-time ultrasound (US) guidance. Locate, align, mark, puncture (LAMP) requires the extra step of marking the skin at two points over the path of the vein and proceeding with direct visualization as in LAP. The difference in success between these two techniques was compared among variably experienced emergency physician and emergency nurse operators. ⋯ LAMP did not improve success of USGPIVA in variably experienced operators. Experience was associated with higher rates of success for USGPIVA.

The authors aimed to determine whether certain emergency department (ED) triage "presenting complaint" descriptions are associated with shorter or longer waiting times, when compared with matched controls. ⋯ Waiting times for patients with certain presenting complaints are significantly associated with triage presenting complaint descriptions. It is likely that these descriptions allow EPs to selectively seek or avoid patients with liked or disliked complaints, respectively. The impact of this for patients and ED flow needs investigation.

The objectives were to describe presentation characteristics and health care utilization information pertaining to dizziness presentations in U.S. emergency departments (EDs) from 1995 through 2004. ⋯ In terms of number of visits and important utilization measures, the impact of dizziness presentations on EDs is substantial and increasing. CT/MRI utilization rates have increased more than any other test.
