Best Case Ever 51 – Anticoagulants and GI Bleed with Walter Himmel

In anticipation of Episode 88 and 89: DOACs Use, Misuse and Reversal with the president of Thrombosis Canada and world renowned thrombosis researcher Dr. Jim Douketis, internist and thrombosis expert Dr. Benjamin Bell and 'The Walking Encyclopedia of EM' Dr. Walter Himmel, we have Dr. Himmel telling us the story of his Best Case Ever on anticoagulants and GI bleed. He discusses the most important contraindication to DOACs, the importance of not only attempting to reverse the effects of anticoagulants in a bleeding patient but managing the bleed itself as well as more great pearls. In the upcoming episodes we'll run through 6 cases and cover the clinical use of DOACs, how they work, safety, indications, contraindications, management of minor, moderate and severe bleeding, the new DOAC reversal agents, management of DVT with DOAC anticoagulants, stroke prevention in atrial fibrillation with DOACs and much more...

Episode 68 Emergency Management of Sickle Cell Disease

A recent needs assessment completed in Toronto found that Emergency providers are undereducated when it comes to the Emergency Management of Sickle Cell Disease. This became brutally apparent to me personally, while I was researching this topic. It turns out that we’re not so great at managing these patients. Why does this matter? These are high risk patients. In fact, Sickle Cell patients are at increased risk for a whole slew of life threatening problems. One of the many reasons they are vulnerable is because people with Sickle Cell disease are functionally asplenic, so they’re more likely to suffer from serious bacterial infections like meningitis, osteomyelitis and septic arthritis. For a variety of reasons they’re also more likely than the general population to suffer from cholycystitis, priapism, leg ulcers, avascular necrosis of the hip, stroke, acute coronary syndromes, pulmonary embolism, acute renal failure, retinopathy, and even sudden exertional death. And often the presentations of some of these conditions are less typical than usual. Those of you who have been practicing long enough, know that patients with Sickle Cell Disease can sometimes present a challenge when it comes to pain management, as it’s often difficult to discern whether they’re malingering or not. It turns out that we’ve probably been under-treating Sickle Cell pain crisis pain and over-diagnosing patients as malingerers. Then there are the sometimes elusive Sickle Cell specific catastrophes that we need to be able to pick up in the ED to prevent morbidity, like Aplastic Crisis for example, where prompt recognition and swift treatment are paramount. A benign looking trivial traumatic eye injury can lead to vision threatening hyphema in Sickle Cell patients and can be easy to miss. In this episode, with the help of Dr. Richard Ward, Toronto hematologist and Sickle Cell expert, and Dr. John Foote, the Residency Program Director for the CCFP(EM) program at the University of Toronto, we’ll deliver the key concepts, pearls and pitfalls in recognizing some important sickle cell emergencies, managing pain crises, the best fluid management, appropriate use of supplemental oxygen therapy, rational use of transfusions and more...

Best Case Ever 38 Sickle Cell Acute Chest Syndrome

Sickle Cell Acute Chest Syndrome remains the leading cause of death in patients suffering from Sickle Cell Disease. In his Best Case Ever, Dr. Richard Ward, a hematologist with a special interest in Sickle Cell Disease, describes a case of a Sickle Cell Disease patient who presents with what appears to be a simple pain crisis, but turns out to be a devastating Acute Chest Syndrome. He gives us the key clinical pearls and pitfalls to make this often elusive diagnosis early so that life-saving treatment can be initiated in a timely manner. This is in anticipation of the upcoming episode on The Emergency Management of Sickle Cell Pain Crisis with Dr. Ward and Dr. John Foote.

Episode 65 – IV Iron for Anemia in Emergency Medicine

For years we’ve been transfusing red cells in the ED to patients who don’t actually need them. A study looking at trends in transfusion practice in the ED found that about 1/3 of transfusions given were deemed totally inappropriate. As we explained in previous EM Cases episodes, there have been a whole slew of articles in the literature over the years that have shown that morbidity and mortality outcomes with lower hemoglobin thresholds, like 70g/L for transfusing ICU patients (TRICC trial), patients in septic shock (TRISS trial), and patients with GI bleeds are similar to outcomes with traditional higher hemoglobin thresholds of 90 or 100g/L. We’re simply transfusing blood way too much! The American Association of Blood Banks in conjunction with the American Board of Internal Medicine’s Choosing Wisely campaign, as one of its 5 statements on overuse of procedures, stated, “don’t transfuse iron deficiency without hemodynamic instability”. So, in this episode with the help of Transfusion specialist, researcher and co-author of the American Association of Blood Banks transfusion guidelines Dr. Jeannie Callum, Transfusion specialist and researcher Dr. Yulia Lin, and 'the walking encyclopedia of EM' Dr. Walter Himmel, we give you an understanding of why it’s important to avoid red cell transfusions in certain situations, why IV iron is sometimes a better option in a significant subset of anemic patients in the ED, and the practicalities of exactly how to administer IV iron.
