Ultrasound in Skin and Soft Tissue Infection

POCUS vs the Clinical Exam

By Michael Prats, MD on 09/25/17 02:00 AM

Have you ever stabbed into an abscess only to have nothing come out? Have you missed an abscess because you thought it was just cellulitis? In theory, ultrasound should be able to help us here by finding that magical pocket beneath the skin that is just asking to be drained. Does the literature support this? Is ultrasound superior to the exam alone? This metaanalysis takes a look at the studies that have been done to find out.


Lung and Cardiac Ultrasound Protocol for Acute Heart Failure

A quick diagnosis?

By Michael Prats, MD on 09/11/17 02:00 AM

Ultrasound can be helpful for diagnosing acute heart failure - mainly by looking for signs of pulmonary edema and poor systolic heart function. Previous results have shown that ultrasound is accurate for the diagnosis, but maybe you're worried that it takes too long. This article tries to test a simple and fast ultrasound protocol that can maintain accuracy in making the diagnosis.


TAPSE to Diagnose Pulmonary Embolism

Feasible and/or useful?

By Michael Prats, MD on 08/28/17 02:00 AM

Alright, we all know that TAPSE (tricuspid annular plane systolic excursion) is a fun word to say, but the question is whether or not it can be used in the emergency department to help diagnose someone with a pulmonary embolism. The TAPSE is a marker of right heart strain, and we know that PEs can cause right heart strain - seems like a reasonable idea, right? Well this article takes a look to see if this is something that can be done in the ED and whether or not it is accurate for the diagnosis.

Have you been living under a rock? If not - then you know that POCUS doesn't help hypotensive patients. Well...maybe don't believe all the hype. We will cover this in a podcast later, but for now you should read it yourself!
