G.E.L. 100

Well...we finally made it. This is the 100th episode of the Ultrasound G.E.L. Podcast! The whole team is on this one, and we discuss thoughts sent in by our listeners on the future of point-of-care ultrasound research. Also reflections, plans, and thank yous. https://www.ultrasoundgel.org/100

VExUS

You may have heard whispers of a magical new way to determine if your patient has too much fluid on board. The VExuS (Venous Excess UltraSound) grading system has been described as a way to use the IVC in combination with abdominal organ doppler in order to determine the degree of venous congestion. This is the first study that takes a look at the VExUS system to see if it can predict acute kidney injury in post-operative patients. https://www.ultrasoundgel.org/99 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7142196/

COVID-19 Severity

We haven't discussed COVID-19 for a long time, despite the explosion of POCUS articles on how ultrasound can be used during this pandemic. Many of the articles have focused on the accuracy of POCUS for making the diagnosis, or comparing the ultrasound findings to those on CT. These are helpful, but now what we really want are studies that help establish that POCUS is helping with delivering patient care - either diagnostically or prognostically. This article seems to take the first step in this direction by examining the prognostic utility of lung ultrasound in this disease. https://www.ultrasoundgel.org/98 https://pubmed.ncbi.nlm.nih.gov/32728966/

Return of the Aortic Dissection

We are making some headway in the evidence behind using point-of-care ultrasound in aortic emergencies. This study takes a look at sensitivity and specificity for acute aortic dissection (which has been a few times before) and also compares POCUS to a control group to see if it causes delays or improves times to diagnosis or treatment (has not been done prospectively before). They even look at mortality! https://www.ultrasoundgel.org/97 https://pubmed.ncbi.nlm.nih.gov/31971274/

Shoulder Dislocation Revisited

People have been using POCUS to diagnosis shoulder dislocation for a while now, although it is far from standard of care in most places. We have seen that it is really accurate compared to xray, but this well-done study adds some important information to the existing literature. They measure the glenohumeral distance in an attempt to make a quantifiable cut-off point for dislocation. They also take a look at potential time savings of ultrasound compared to xray! https://www.ultrasoundgel.org/96 https://pubmed.ncbi.nlm.nih.gov/32111508

Deep Learning for Peripheral IV Anatomy

Deep learning is a branch of artificial intelligence that holds a lot of promise for point-of-care ultrasound, but we don't have much data on how it performs. The fearless investigators in this fascinating study train a deep learning algorithm to recognize sonographic anatomy of the upper extremity and then pit it against expert POCUS users to see who can interpret the images most accurately! https://www.ultrasoundgel.org/95 https://pubmed.ncbi.nlm.nih.gov/32181922/

Chest Tube Location

Placing a tube thoracostomy (aka chest tube) is a very useful procedure but can have complications of injuring the diaphragm or intraabdominal organs. Traditionally, the location for placement is selected using anatomic landmarks to find the correct intercostal space. This study questions the safety of this traditional location by using point-of-care ultrasound to visualize diaphragm movement during respirations. Is this the start of ultrasound-assisted chest tubes? https://www.ultrasoundgel.org/94 https://pubmed.ncbi.nlm.nih.gov/32333800/

How to Do POCUS Research - Part 2

We are back with Part 2 of discussing POCUS research with renowned expert and researcher, Michael Gottlieb. More pearls, pitfalls, tips, and tricks to help you step up your POCUS research game. This is the final episode in this two-part special edition, and we wrap it up as always with some take home points! https://www.ultrasoundgel.org/93

How to Do POCUS Research - Part 1

We have reviewed a lot of POCUS articles on this podcast, but we don't often talk about the process of performing a research study. On this episode, we bring on world-class POCUS expert and researcher Michael Gottlieb to discuss the ins and outs of performing, publishing, and reviewing ultrasound research studies. This is Part 1 of 2. https://www.ultrasoundgel.org/92

Pediatric Peritonsillar Abscess

For peritonsillar abscesses, sometimes you need imaging to make the diagnosis clear. Many turn to CT, but ultrasound offers an appealing alternative. A transcervical approach can be used which is likely less uncomfortable than the intra-oral method. This study looks at the implementation of a transcervical ultrasound protocol in a pediatric emergency department to see if it helps this population. https://www.ultrasoundgel.org/91 https://www.ncbi.nlm.nih.gov/pubmed/31713253
