Review Meta Analysis
The use of pleural fluid procalcitonin and C-reactive protein in the diagnosis of parapneumonic pleural effusions: a systemic review and meta-analysis.
We aimed to perform a systematic review and meta-analysis of the diagnostic performance of pleural fluid procalcitonin (PCT) or C-reactive protein (CRP) in differentiating parapneumonic effusion in patients with pleural effusion. ⋯ The existing literature suggests that both pleural fluid and serum PCT tests have low sensitivity and specificity for differentiating parapneumonic effusion from other etiologies of pleural effusion. Compared with PCT, serum CRP has higher specificity and a higher positive likelihood ratio, and thus, it has a higher rule-in value than PCT.

Emergency department (ED) clinicians are not typically involved in the long-term management of patients' anticoagulation therapy, but they are responsible for decision making for emergency conditions requiring anticoagulation, such as acute venous thromboembolism (VTE). In addition, emergency physicians are often faced with patients who present first to the ED with conditions that may prompt long-term anticoagulation upon hospital discharge, such as atrial fibrillation (AF), or who have acute or potential bleeding complications from anticoagulation. ⋯ Knowledge of the appropriate clinical use and safety concerns of the new anticoagulants is imperative as they become more frequently prescribed, and their potential uses in the ED setting represent an important aspect of continuing education for emergency physicians.

Randomized Controlled Trial
Chest compressions performed by ED staff: a randomized cross-over simulation study on the floor and on a stretcher.
Multiple factors may contribute to the observed survival variability following in-hospital cardiopulmonary resuscitation (CPR). While in-hospital CPR is most often performed on patients lying on a bed or stretcher, CPR training uses primarily manikins placed on the floor. We analyzed the quality of external chest compressions (ECC) in simulated cardiac arrest scenarios occurring both on a stretcher and on the floor. ⋯ The quality of chest compressions performed by ED staff was below 2005 guideline standards, with decreased ECC depth during CPR on a stretcher. Annual refresher courses should be implemented in the ED, with a focus on obtaining required ECC depth while standing next to a stretcher.

Multicenter Study
Decrease in central venous catheter placement due to use of ultrasound guidance for peripheral intravenous catheters.
Obtaining intravenous (IV) access in the emergency department (ED) can be especially challenging, and physicians often resort to placement of central venous catheters (CVCs). Use of ultrasound-guided peripheral IV catheters (USGPIVs) can prevent many "unnecessary" CVCs, but the true impact of USGPIVs has never been quantified. This study set out to determine the reduction in CVCs by USGPIV placement. ⋯ Ultrasound prevented the need for CVC placement in 85% of patients with difficult IV access. This suggests that USGPIVs have the potential to reduce morbidity in this patient population.

Multicenter Study
Duration of well-controlled core temperature correlates with neurological outcome in patients with post-cardiac arrest syndrome.
Detailed procedures for optimal therapeutic hypothermia (TH) have yet to be established. We examined how duration of well-controlled core temperature within the first 24 hours after cardiac arrests (CA) correlated with neurological outcomes of successfully resuscitated out-of-hospital CA (OHCA) patients. ⋯ TH maintained at target temperature of 33 °C ± 1 °C over 18 hours independently correlated with favorable neurological outcome. Therefore, stable core temperature control may improve neurological outcome of successfully resuscitated OHCA.
