Randomized Controlled Trial
Randomized trial of tourniquet vs blood pressure cuff for target vein dilation in ultrasound-guided peripheral intravenous access.
Ten percent of the time, peripheral intravenous access (PIV) is not obtained in 2 attempts in the emergency department. Typically, a tourniquet is used to dilate the target vein; but recent research showed that a blood pressure (BP) cuff improves dilation, which may translate to increased PIV success. ⋯ Tourniquet is superior to BP cuff for target vein dilation in ultrasound-guided PIV.

When a previously healthy adult experiences atraumatic cardiac arrest, providers must quickly identify the etiology and implement potentially lifesaving interventions such as advanced cardiac life support. A subset of these patients develop cardiac arrest or periarrest due to pulmonary embolism (PE). For these patients, an early, presumptive diagnosis of PE is critical in this patient population because administration of thrombolytic therapy may significantly improve outcomes. ⋯ Despite potentially improved outcomes with thrombolytic therapy, this intervention is not without risks. Patients exposed to thrombolytics may experience major bleeding events, with the most devastating complication usually being intracranial hemorrhage. To optimize the risk-benefit ratio of thrombolytics for treatment of cardiac arrest due to PE, the clinician must correctly identify patients with a high likelihood of PE and must also select an appropriate thrombolytic agent and dosing protocol.

We sought to evaluate the performance of an abbreviated version of the Denver HIV Risk Score in 2 urban emergency departments (ED) with known high undiagnosed HIV prevalence. ⋯ An abbreviated version of the Denver HIV Risk Score had comparable performance to that reported previously, offering a promising alternative strategy for HIV screening in the ED where limited sexual risk behavior information may be obtainable.

Suicide by organophosphate insecticide (OPI) poisoning is a major clinical concern (predominantly in developing countries), and 200000 deaths occur annually worldwide. Red cell distribution width (RDW) has been used to predict outcome in several clinical conditions. Here, we aimed to investigate the relationship between the RDW and 30-day mortality during OPI poisoning. ⋯ This study showed that RDW is an independent predictor of 30-day mortality in patients with OPI poisoning.

Gastrointestinal hemorrhage (GIH) is a common complaint seen in the emergency department (ED) and carries a small but significant mortality rate. The principal purpose of this investigation was to determine whether an ED venous lactate as part of initial laboratory studies is predictive of mortality in patients admitted to the hospital for GIH. ⋯ Elevated initial lactate drawn in the ED can be associated with in-hospital mortality for ED patients with acute GIH. Prospective validation studies are warranted.
