Increased Sensitivity of Focused Cardiac Ultrasound for Pulmonary Embolism in Emergency Department Patients With Abnormal Vital Signs.

Background: Focused cardiac ultrasound (FOCUS) is insensitive for pulmonary embolism (PE). Theoretically, when a clot is large enough to cause vital sign abnormalities, it is more likely to show signs of right ventricular dysfunction on FOCUS, although this has not been well quantified. A rapid bedside test that could quickly and reliably exclude PE in patients with abnormal vital signs could be of high utility in emergency department (ED) patients.

Guiding Cardiopulmonary Resuscitation with Focused Echocardiography: A Report of Five Cases.

Focused transthoracic echocardiography has been used to determine etiologies of cardiac arrest and evaluate utility of continuing resuscitation after cardiac arrest. Few guidelines exist advising ultrasound timing within the advanced cardiac life support algorithm. Natural timing of echocardiography occurs during the pulse check, when views are unencumbered by stabilization equipment or vigorous movements.

The Practice and Implications of Finding Fluid During Point-of-Care Ultrasonography: A Review.

Importance: Point-of-care ultrasonography (POCUS) is an increasingly affordable and portable technology that is an important part of 21st-century medicine. When appropriately used, POCUS has the potential to expedite diagnosis and improve procedural success and safety. POCUS is now being adopted in medical education as early as the first year of medical school.

Impact of point-of-care ultrasonography on ED time to disposition for patients with nontraumatic shock.

Study Objective: Nontraumatic shock in the emergency department (ED) has multiple causes and carries in-hospital mortality approaching 20%, underscoring the need for prompt diagnosis and treatment. Diagnostic ultrasonography at the point of care is one method that may improve the ability of ED physicians to quickly diagnose and treat. This study assesses the effect of the use and timing of point-of-care (POC) ultrasonography on time to disposition request.

Cost-effectiveness of the Cardiac Component of the Focused Assessment of Sonography in Trauma Examination in Blunt Trauma.

Background: Blunt cardiac injury severe enough to require surgical intervention (sBCI) is an exceedingly rare event occurring in approximately 1 out of every 1600 trauma patients. While performing the cardiac component of the Focused Assessment of Sonography in Trauma (cFAST) exam is effective in penetrating trauma, it is unclear whether it is of value in blunt trauma given the low prevalence of sBCI, the imperfect test characteristics of the FAST exam, and the rate of incidental pericardial effusion.

Objective: The objective was to determine through decision analysis whether performing the cFAST exam is cost-effective in the evaluation of hypotensive and normotensive blunt trauma patients.

The "5Es" of emergency physician-performed focused cardiac ultrasound: a protocol for rapid identification of effusion, ejection, equality, exit, and entrance.

Emergency physician (EP)-performed focused cardiac ultrasound (EP FOCUS) has been increasingly recognized as a crucial tool to help clinicians diagnose and treat potentially life-threatening conditions. The existing literature demonstrates a variety of EP FOCUS applications and protocols; however, EP FOCUS is not taught, practiced, or interpreted consistently between institutions. Drawing on over 12 years of experience in a large-volume, high-acuity academic emergency department, we have developed a protocol for teaching and performing EP FOCUS known as "The 5Es," where each E represents a specific assessment for immediately relevant clinical information.

Prevalence and clinical importance of alternative causes of symptoms using a renal colic computed tomography protocol in patients with flank or back pain and absence of pyuria.

Objectives: The study was undertaken to determine the prevalence and clinical importance of alternative causes of symptoms discovered in patients undergoing flank pain protocol (FPP) computed tomography (CT) scans in patients with classic symptoms of kidney stone (flank pain, back pain, or both) without evidence of urine infection.

Methods: This was a retrospective observational analysis of all adult patients undergoing FPP CT scans at two emergency departments (EDs) between April 2005 and November 2010. All CTs (N = 5,383) were reviewed and categorized as "no cause of symptoms seen on CT," "ureteral stone as cause of symptoms," or "non-kidney stone cause of symptoms.

Screening for abdominal aortic aneurysm in asymptomatic at-risk patients using emergency ultrasound.

Objective: Abdominal aortic aneurysm (AAA) is a deadly but often clinically silent disease. Patients at increased risk are elderly men with risk factors for vascular disease who may not have adequate screening through primary care. We sought to examine the prevalence and feasibility of screening for AAA in at-risk patients presenting for unrelated complaints using emergency physician-performed bedside ultrasound.
