Anterior vs Lateral Lung Fields in Heart Failure

Do we need both?

By Michael Prats on 10/28/19 06:00 AM

Suspected acute heart failure is a great reason to use point-of-care ultrasound. It can tell you in seconds if this patient is up to their neck in pulmonary edema. Knowing that interstitial edema is more common in dependent areas of the lung, one would think that the lateral areas of the lung fields would be most sensitive for the diagnosis. Likewise, if there is enough pulmonary edema to fill up the anterior lung fields, this theoretically should be pretty specific. But is this actually true?! These authors investigate the issue. https://www.ncbi.nlm.nih.gov/pubmed/30665807


Small Bowel Obstruction (#2)

Revisiting The Accuracy of POCUS

By Michael Prats on 10/15/19 06:00 AM

POCUS can be used to visualize small bowel obstruction (SBO) fairly easily. It has proven itself superior to xrays and has some advantages over CT, which for most people is the standard for diagnosis. Although initial work was quite promising, there were no large studies done confirming the accuracy of ultrasound for this purpose. In this podcast we examine the latest study (plus discuss a bonus similar one) that reveals maybe this is not as good as we thought! https://www.ncbi.nlm.nih.gov/pubmed/30762916


LVOT Opening in Cardiac Arrest

More Support for TEE?

By Michael Prats on 09/30/19 06:00 AM

There are many ways that TEE can help you in cardiac arrest. One of these is to monitor your chest compressions to make sure they are actually doing what you want. Although this makes sense intuitively and is supported by animal models, there has not been a lot of evidence to date. This article takes a step in that direction by showing some data on outcomes in humans. https://www.ncbi.nlm.nih.gov/pubmed/30825552
