With the help of a special guest, EBM guru Dr. Ken Milne of the The SGEM, Anton and Justin look at all the various potential indications for TXA and review the available evidence. Should we be using TXA for epistaxis, postpartum hemorrhage, hyphema or hemoptysis? Is it a miracle drug that stops all bleeding? Or has it been drastically overhyped? Was CRASH-2 enough to be definitive, or does the classic EBM mantra of "we need more studies" remain true?...

Dr. Jeannie Callum, Dr. Andrew Petrosoniak and Dr. Barbara Haas join Anton in answering the questions: How do you decide when to activate the MHP? How do you know when it is safe to terminate the MHP? What lab tests need to be done, how often, and how should the results be shared with the clinical team? Once the dust settles, what do we need to tell the patient and/or their family about the consequences of being massively transfused? What should be the lab resuscitation targets? Why is serum calcium important to draw in the ED for the patient who is exsanguinating? How do we mitigate the risk of hypothermia? What can hospitals do to mitigate blood wastage? If someone is on anti-platelets or anticoagulants what is the best strategy to ensure the docs in the ED know what to give and how much?

As EM Cases has grown and expanded over the past 7 years I've had the pleasure of working with a team of talented people. This Best Case Ever was produced by two all-star EM residents from Ottawa, podcaster Dr. Rajiv Vairavanathan and editor Dr. Richard Hoang. In this all-resident Best Case Ever we interview Dr. Chris Belcher from University of Kentucky about TTP - Thrombotic Thrombocytopenic Purpura, that rare but often elusive clotting disorder that picks off multiple organs and has a near 100% mortality rate without treatment...

In this Part 2, DOACs Bleeding and Reversal we discuss the management of bleeding in patients taking DOACs with minor risk bleeds, like epistaxis where local control is easy to access, moderate risk bleeds, like stable GI bleeds and high risk bleeds, like intracranial hemorrhage. We answer questions such as: How do we weigh the risks and benefits of stopping the DOAC? When is reversal of the DOAC is advised? How best do we accomplish the reversal of DOACs? Is there any good evidence for the newest reversal agent? When should we stop DOACs for different procedures, and when should we delay the procedure?

As we get better at picking up thromboembolic disease, and the indications for Direct Oral Anticoagulants (DOACs) widen, we're faced with increasingly complex decisions about when to start these medications, how to start them, when to stop them and how to manage bleeding associated with them. There’s a lot that we need to know about these drugs to minimize the risk of thromboembolism in our patients while at the same time minimizing their risk of bleeding...

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...

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...

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.

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.
