Emergency Physician Accuracy in Identifying and Grading Hydronephrosis

Can POCUS make the grade?

By Michael Prats, MD on 05/21/18 06:00 AM

As more and more emergency physicians are using point-of-care ultrasound to assess for hydronephrosis in the setting of renal colic, it becomes important to determine how accurate they are for the diagnosis. This study takes previously recorded clips and compares the EP interpretation to a radiologists interpretation. The idea is to see if EPs can determine the presence or absence of hydro, as well as the grade of it, compared to a radiologist looking at the same images. Both are then compared to CTs done in the same patients for a second standard of comparison. This brings to light interesting findings as well as questions regarding the best standard of comparison in this practice.


POCUS to Diagnosis Gastric Content

Can you stomach it?

By Michael Prats, MD on 05/07/18 06:00 AM

Usually in ultrasound we think of the stomach as something that gets in the way or gives us a false positive LUQ view in the FAST. But what if visualizing the stomach could actually be helpful? In some scenarios, such as prior to anesthesia, sedation, or a procedure, it might be nice to know if the patient has a full stomach with the potential to aspirate. These authors test out the accuracy of POCUS for this purpose in healthy volunteers.


Flexor Tenosynovitis

Giving the Finger to POCUS

By Michael Prats, MD on 04/23/18 06:00 AM

Flexor tenosynovitis is a bad infection in the finger. It usually requires surgical intervention for treatment. The current standard of diagnosis is primarily clinical, sometimes with the help of blood tests. Since the disease process should produce a fluid collection around the flexor tendon sheath - the idea in this study is that perhaps ultrasound can visualize that fluid and clench the diagnosis. This would lead to ensuring the proper treatment to those who need it and potentially avoiding an unnecessary operation for those who don't. So how well does this plan work out? Should we be doing this routinely?
