TEE1Q: What is the utility of transesophageal echocardiography in the emergency department?

A: Point of care echo, typically done via the transthoracic approach (TTE), has transformed emergency care over the past 25 years. A routine part of the FAST exam in the assessment for traumatic hemopericardium, TTE is additionally used in cardiac arrest and is indicated for the focused assessment of LV and RV function, assessment of the IVC, and guiding procedures.(1)

Cardiac Journal Summary

Imagine the following phone call:

ED Physician: “Hey, I need to admit an elderly female for fever.”
Hospitalist: “What’s the source?”
ED Physician: “Hmmm … I don’t really have one. Urine and Chest X-Ray are negative, and the mental status is normal.”
Hospitalist: “Can’t they go home?”
ED Physician: “No, too high of a risk.”

I am certain that many of us have had the same conversation while working. Read through Tintinalli, Rosens, etc, and the cited mortality rates in the elderly are between 7 to 10%. With these poor outcomes, when do we order three blood cultures for the fever of unknown origin and presumptively treat for endocarditis?

Tips & Tricks: The Big Squeeze - Cardiac Contractility and Right Ventricular Strain Assessment

EPSS1Leading to approximately 1.2 million annual visits, renal colic is a common presentation amongst emergency department patients (1). Nephrolithiasis remains the most common cause of renal colic. As computed tomography (CT) imaging is highly sensitive and specific for renal stones, many practitioners have adopted the routine use of CT in the initial evaluation of renal colic patients. However, in the younger patient population presenting with renal colic, the ionizing radiation associated with CT imaging is not necessary as an initial assessment.

Peter’s Pet Peeves: Ultrasound Hygiene

“!#$@*&$%^!”. Yes, I have been known to utter more than my fair share of F-bombs, but some things make me go on a blitzkrieg. Bombarding the whole ED. Without concern for any collateral damage from my tirade, I rant on. “John Effen Jingleheimer Schmidt!”

What upsets me so much? See the two pics below. 

US Hygiene2US Hygiene1Who could leave the probe smeared in blood (or fluid from some bodily orifice)? Meanwhile, does anyone really think that a $2 bottle of gel is more important than a $10,000 linear array probe? Or why leave it unplugged, letting the battery drain dead? Now it won’t turn power on for that hypotensive patient in room 3!

Fellow’s Spotlight: A Look at EUS Fellows’ Projects

Grace W. Wanjiku MD
Yale University, New Haven, CT

Grace Wanjiku Project
Grace, an EUS fellow at Yale, is collaborating with the Emergency Medicine Kenya Foundation to train Kenyan rural health care providers on E-FAST, focused echocardiography, and obstetric ultrasonography. This novel program begins with a pre-course self-study multimedia manual and pre-course testing. After completing a 3-day hands-on training session, a post-test is administered. Then, 3-months after the training session, an in-facility evaluation is performed and then the participants receive a scheduled refresher training.
