Inferior Vena Cava Collapsibility for Fluid Responsiveness

yes or no?

By Michael Prats, MD on 07/31/17 02:00 AM

Ultrasound of the IVC is the people's volume responsiveness test. The idea is that you can non-invasively tell if a patient will benefit from getting more IV fluids. Everybody wants this to work so we can have a simple test to help us in critical situations. It is more reliable in mechanically ventilated patients with a fixed tidal volume but how about the non-intubated patient? Can we trust it?


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.


Extravasation of IVs placed by Ultrasound

The risk is real

By Michael Prats, MD on 10/24/16 04:00 AM

This article examines an issue that we all face. It can be frustrating to take the time to place an IV only to have it blow during a vital CT scan. Is this a result of the IV being placed by ultrasound or a result of the underlying causes that led to the patient having poor venous access? Come find out.
