Speckle tracking? Is that the technology that the government uses to mine data from your phone?! No - totally different! This is an ultrasound technology that recognizes tiny specks in the myocardium, allowing for a measurement of the movement of the heart wall. This has the potential to quantify the contractility of different parts of the heart, and therefore can be used to help diagnose numerous cardiac pathologies. At this time, not many people are using this in the emergency department. This is the first study to take a look to see if this is feasible and if it is accurate in diagnosing patients with acute coronary syndrome.

Ultrasound was made for the diagnosis of small bowel obstruction. It loves when air filled things are turned into fluid filled things - its helps us see it better. When the bowel gets backed up and distends with digested cheeseburgers, ultrasound is there to save the day. As easy as this may seem, it has not been well studied. There are a few small studies that show it can be accurate compared to a CT, but without a large body of evidence - a lot of people are (quite reasonably) unwilling to put their faith in it. Well, we can't say this study is going to turn all that around, but its one more piece of the puzzle of figuring out how we can use POCUS for this diagnosis.

Are you sick of hearing about ultrasound and cardiac arrest? Do you think to yourself - "Why can't everyone just do it my way?." Well - for better or for worse (we think for the better), there are going to be more and more ultrasound and cardiac arrest articles. The reason is that point of care ultrasound can help so much in this situation, yet - it has also been shown to put people at risk for longer times without CPR. So what do we do? This article presents the CASA exam, a cardiac arrest ultrasound protocol, as a way to standardize the exam and (hopefully) minimize pauses in CPR.
