Diagnostic accuracy and temporal impact of ultrasound in patients with dyspnea admitted to the emergency department.

Objective: Few studies have prospectively evaluated the diagnostic accuracy and temporal impact of ultrasound in the emergency department (ED) in a randomized manner. In this study, we aimed to perform a randomized, standard therapy controlled evaluation of the diagnostic accuracy and temporal impact of a standardized ultrasound strategy, versus standard care, in patients presenting to the ED with acute dyspnea.

Methods: The patients underwent a standardized ultrasound examination that was blinded to the team caring for the patient.

Mitral valve velocity time integral and passive leg raise as a measure of volume responsiveness.

Background: Fluid responsiveness is an important topic for clinicians. Aggressive hydration has been shown to lead to worse outcomes. The aim of this study was to investigate the sensitivity and specificity of mitral valve (MV) velocity time integral (VTI) as a non-invasive marker of volume responsiveness.

Corrected carotid flow time and passive leg raise as a measure of volume status.

Background: The aim of this study was to investigate the value of corrected carotid flow time (FTc) with passive leg raise (PLR) as a non-invasive marker of volume status in end stage renal disease (ESRD) patients.

Methods: Prospective observational study of ESRD patients presenting to the Emergency department requiring hemodialysis. The common carotid artery was evaluated in long axis.

Bedside Echocardiography and Passive Leg Raise as a Measure of Volume Responsiveness in the Emergency Department.

Objectives: The aim of this study was to investigate the value of bedside echocardiography with a passive leg raise as a noninvasive marker of volume responsiveness.

Methods: This work was a prospective observational study of patients with end-stage renal disease presenting to the emergency department. The left ventricular outflow tract (LVOT) velocity time integral (VTI) was obtained.
