This is the first post in the Elemental EM series, a rapid review of core emergency medicine topics. This post covers myasthenia gravis.

This week's toxcard is on treatments used for beta blocker and calcium channel blocker toxicity.

Sepsis is a common disease, but sometimes, we need some assistance with the diagnosis and resuscitation of these patients. Can biomarkers help us, or are we wasting time using these measures? What's wrong with just the time-honored history and exam?

Thromboelastography is a mechanism of assessing coagulation based upon the viscoelastic properties of whole blood, and when compared to other coagulation assessments, this test allows for an assessment of near real-time, in-vivo clotting capacity. The point-of-care assay, which uses graphic interpretation of thromboelastography (the TEG), offers the opportunity for an expedited assessment of coagulopathies (thrombocytopenia, factor deficiency, heparin effect, hypofibrinogenemia, and hyperfibrinolysis). How can you use this modality in the ED? This post is full of pearls on interpreting TEG.

Epinephrine is a key component of ACLS measures. But what does the data show? This post evaluates the ACLS recommendations for epinephrine in cardiac arrest, the literature behind its use, and future directions.

The prehospital environment is where emergency medicine begins. EMS providers must function in some of the most difficult conditions with limited supplies. FOAMed can allow emergency providers of all levels to stay up to date with cutting edge resuscitation and prehospital literature. This post evaluates EMS/prehospital FOAMed resources.

The burn patient: a review of the ins and outs of ED management.

Bi-level ventilation is commonly used in patients with respiratory failure in the emergency department. This is a brief review of the indications for bi-level ventilation as well as a review of the complications of this popular ventilation/oxygenation method.
