    PROFUNDUS or Just SUPERFICIALIS? Dissecting Acute Aortic Syndromes

    Have you ever had a patient's aortic intima and media peel off each other like the plastic casing from a cheap laptop and wish had more tools than just shipping them off to the CT scanner? Well, the D-dimer and the suprasternal aortic notch views may be a solution to your problems!

    Wells Score of 12.5

    This week, we are embolizing information from my microphone straight into your ears, as I have a systematic review covering the accuracy of DVTs performed by EM providers and a trial looking at how well a new diagnostic measure called the RV bubble time does in looking for RV dysfunction.

    GI Bleeds, VTI, and You

    On this episode, we cover two papers on the use of ultrasound hemodynamic findings in clinically evaluating blood loss: one in suspected upper GI bleeding to risk stratify patients into transfusion candidates vs not at the bedside, and the other covering an emerging use of wearable ultrasound to relate carotid Doppler findings with cardiac output. Show notes for paper 1 (Ayar et al)Citation: Ayar MS, Baydın A, Ustaoglu M, Caliskan F, Erenler AK. Inferior vena cava collapsibility index and stroke volume as predictors of blood transfusion in upper gastrointestinal bleeding in the emergency department.
