Episode 94 UTI Myths and Misconceptions

In 2014, the CDC reported that UTI antibiotic treatment was avoidable at least 39% of the time. Why? Over-diagnosis and treatment results from the fact that asymptomatic bacteriuria is very common in all age groups, urine cultures are frequently ordered without an appropriate indication, and urinalysis results are often misinterpreted. Think of the last time you prescribed antibiotics to a patient for suspected UTI – what convinced you that they had a UTI? Was it their story? Their exam? Or was it the urine dip results the nurse handed to you before you saw them? Does a patient’s indwelling catheter distort the urinalysis? How many WBCs/hpf is enough WBCs to call it a UTI? Can culture results be trusted if there are epithelial cells in the specimen? Can a “dirty” urine in an obtunded elderly patient help guide management?...

Episode 93 – PALS Guidelines

I remember when I started practicing emergency medicine a decade and a half ago it seemed that any kid who came to our ED in cardiac arrest died. I know, depressing thought. But, over the past 15 years, survival to discharge from pediatric cardiac arrest has markedly improved, at least for in-hospital arrests. This is probably mostly due to an emphasis on high-quality CPR and advances in post-resuscitation care; nonetheless the more comfortable, knowledgeable and prepared we are for the always scary critically ill pediatric patient, the more likely we will be able to resuscitate them successfully - which is always a huge save.

Episode 92 – Aortic Dissection Live from The EM Cases Course

While missing aortic dissection was considered "the standard" in the late 20th century, our understanding of the clinical diagnoses has improved considerably since the landmark International Registry of Aortic Dissection (IRAD) study in 2000. Nonetheless, aortic dissection remains difficult to diagnosis with 1 in 6 being missed at the initial ED visit. With the help of Dr. David Carr we’ll discuss how to pick up atypical presentations of aortic dissection without over-imaging as well as manage them like pros by reviewing: 1. The 5 Pain Pearls, 2. The concepts of CP +1 and 1+ CP, 3. Physical exam pearls, 4. CXR pearls and blood test pitfalls, and 5. The importance of the correct order and aggressive use of IV medications. So with these objectives in mind…
