Author Insight: Ultrasonography versus CT for suspected nephrolithiasis | NEJM

Kidney Stone canstockphoto19503829Are you getting a CT or bedside ultrasound as your first-line diagnostic approach to patients with undifferentiated abdominal or flank pain in whom you suspect kidney stones? In a landmark 15-center, multidisciplinary study published in the New England Journal of Medicine in September 2014, Dr. Rebecca Smith-Bindman (UCSF Department of Radiology) and her research team looked at exactly this question for emergency department patients. In the paper, “Ultrasonography versus CT for suspected nephrolithiasis,” Dr. Smith-Bindman and Dr. Ralph Wang (UCSF Department of Emergency Medicine) kindly joined us on a quick discussion about her paper.

AIR Series: Ob/Gyn Module 2015

Welcome to the seventh ALiEM Approved Instructional Resources (AIR) Module! In an effort to reward our residents for the reading and learning they are already doing online we have created an Individual Interactive Instruction (III) opportunity utilizing FOAM resources for U.S. Emergency Medicine residents. For each module, the AIR board curates and scores a list of blogs and podcasts. A quiz is available to complete after each module to obtain residency conference credit. Once completed, your name and institution will be logged into our private database, which participating residency program directors can access to provide proof of completion.

The Art of Syringe Labeling in the ED

MedicationSyringeDrawThe ‘look-alike, sound-alike’ nature of many drug appearances and names is problematic. In high-stress environments such as the Emergency Department (ED), potential disasters can arise if “drug swap” or other medication errors occur. Drug swap is the accidental injection of the wrong drug.1 The anesthesiology literature contains several published reports presenting various ideas on how to properly label syringes used in the operating room to reduce medication errors. Techniques include color-coding the labels,2 labeling of the plunger,3 double-labeling,4,5 and specific placement of the labels on the syringe.6

PV Card: Focused Deep Vein Thrombosis (DVT) Ultrasound

ultrasound dvtDeep vein thrombosis (DVT) is always a consideration when patients with asymmetric lower extremity swelling. Why is one leg. Two-point focused DVT ultrasonography of the femoral and popliteal veins can be incredibly useful in the Emergency Department when trying to narrow the differential diagnosis. Drs. Margaret Greenwood-Ericksen, Joshua Rempell, and Mike Stone provide a clear, image-based clinical reference tool on this ultrasound technique.
