US-Guided Regional Anesthesia for Acute Pain: The Evidence

Part 1

By Michael Prats on 12/09/19 06:00 AM

Everyone who has ever done one knows that ultrasound guided blocks are great. They seem to help patients, they are fun to do, but are they supported by the evidence? Mike Stone joins in on this two part, special edition dive into the studies out there for performing ultrasound guided regional anesthesia for acute pain.

Speckle Tracking in Pneumothorax

What?! How? Why?

By Michael Prats on 11/25/19 06:00 AM

Speckle tracking is a relatively new ultrasound technology that lets you graph the movement of tissue over time. We know this can be useful to look at cardiac function, but no one dared to try it out on the lung...until now! The idea here is that by using speckle tracking on the pleural line, there might be a higher accuracy in detecting pneumothorax on ultrasound! It sounds crazy...but maybe it's just crazy enough to work.

Early Systolic Notching for Pulmonary Embolism

A New Doppler Sign of Massive and Submassive PE

By Michael Prats on 11/11/19 06:00 AM

A focused echo can go a long way in a patient with a suspected pulmonary embolus (PE). It can be especially valuable in those that are so sick and unstable that you need answers right away. In this way, point-of-care echo has been shown to help to diagnose submassive and massive pulmonary emboli by identifying signs of right heart strain. Echo parameters such as right ventricle diameter and right ventricular function (such as in TAPSE) are often part of the evaluation, but these are not as accurate as we would like. These authors propose a new doppler marker of a submassive or massive PE- enter the Early Systolic Notching pattern.
