Acute Dyspnea

Can ultrasound help?

By Michael Prats, MD on 05/22/17 02:00 AM

Feeling out of breath or having trouble breathing (AKA dyspnea) is a common complaint in the emergency department. We know already that ultrasound can diagnose a number of things that can cause this symptom. This paper takes a look to see how ultrasound can help out the evaluation of a patient who presents with acute dyspnea. More specifically, it looks at the accuracy of diagnosis and time to making the diagnosis compared to an evaluation without ultrasound.

Ultrasound for Posterior Ocular Pathology

I can't believe my eyes

By Michael Prats, MD on 05/08/17 02:00 AM

The eye was made to ultrasound - it is fluid filled and easy to find. Ultrasound can be used to diagnose many causes of acute visual complaints. This is important because often times a) comprehensive dilated fundoscopy is not feasible and b) there are no ophthalmologists around. So how good is it? This study compares point of care ultrasound to an ophthalmologists exam in diagnosing posterior ocular pathology such as retinal detachment, vitreous detachment, and vitreous hemorrhage.

Simplified CVC Confirmation

Only a flush away

By Michael Prats, MD on 04/24/17 02:00 AM

Central lines are often needed in the sickest patient, and after we place them, we usually need to use them quickly. Traditionally, this means tapping your foot anxiously while waiting for a chest xray to confirm that the catheter is in the appropriate place. Well guess what - it turns out that ultrasound is pretty good at determining correct placement, at the bedside, right away. This study attempts to use a simplified flush protocol to see how accurately and how quickly ultrasound can confirm catheters placed in the internal jugular or subclavian veins.
