I know your first thought - is this for real?! The POCUS enthusiasts have gone off the rails again! Well - that very well may be the case, but hear me out- this is a fascinating idea. This article presents a novel strategy for searching for embolic etiologies in the acute phase of ischemic strokes (which means even climbing into CT with a handheld device!). "Why?" you may rightfully ask. That is a really great question, and I'm glad you asked. I guess you will have to check out this episode to find out! https://www.ultrasoundgel.org/102 https://pubmed.ncbi.nlm.nih.gov/32532655/

Ultrasound of the bowel is a relatively new application for POCUS users. It came into the spotlight proving itself with small bowel obstruction, but now we are slowly peristalsing even further down the colon of indications. You may be surprised to find that you can actually see diverticulitis on ultrasound, but it turns out it's not that hard! The question is - how reliable are the sonographic findings? This study is one of the largest to compare POCUS to CT to investigate this important application. https://www.ultrasoundgel.org/101 https://pubmed.ncbi.nlm.nih.gov/32653332/

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

Exploration of the VExUS system in determining venous congestion levels and its potential to predict acute kidney injury post-operatively. Analysis of Doppler waveforms, IVC dilation specificity, and the Vexus score's correlation with kidney injury outcomes post cardiac surgery.

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/

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/

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 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/

Exploring the use of ultrasound for safer chest tube insertion, comparing accuracy to anatomic landmarks. Discussion on diaphragm movement, challenges in identifying insertion points, and benefits of ultrasound guidance. Study on fifth intercostal space location and call for listener ideas for research studies.

Renowned expert and researcher, Michael Gottlieb, shares valuable tips on POCUS research. Topics include assessing research papers, importance of collaboration, effective strategies for research planning and implementation, and navigating POCUS research with feedback and resources.
