Ultrasound in Pediatric Pneumonia

Replacing the chest xray?

By Michael Prats, MD on 10/10/16 04:00 AM

This study looks at how well point of care ultrasound performs in the evaluation for pneumonia in a pediatric emergency department. Two study arms were compared - an ultrasound first approach, in which patients did not necessarily require a chest xray, and a chest xray first approach, followed by an ultrasound. The authors hypothesized that using ultrasound could reduce the number of chest xrays needed. They performed follow up to see if there was any difference in return visits or antibiotic prescriptions. Impressive results followed!

Multiorgan Ultrasound for Pulmonary Embolism

Does combining lung, heart, and vein scans improve test performance?

By Michael Prats, MD on 09/26/16 02:00 AM

We review a prospective study evaluating the accuracy of a combo ultrasound of the lung, heart, and veins to diagnose pulmonary embolism (PE) using CT pulmonary angiography as gold standard. Is it possible to use ultrasound to rule out a PE? Listen to our thoughts and let us know what you think!

Importance of the Left Upper Quadrant View in the FAST exam

How often is the LUQ view useful?

By Michael Prats, MD on 09/12/16 02:00 AM

The left upper quadrant view in the FAST (focused assessment with sonography for trauma) exam can be difficult to get just right. This paper examines how important it is in finding intraabdominal free fluid. The authors reviewed FAST exams to determine how often there is free fluid only in the left upper quadrant. Also, they looked to see which part of the left upper quadrant free fluid went to most often. Spoiler alert: its not the subphrenic space!
