Episode 69 Obesity Emergency Management
Current estimates of the prevalence of obesity are that a quarter of adult Canadians and one third of Americans are considered obese with approximately 3% being morbidly obese. With the proportion of patients with a BMI>30 growing every year, you’re likely to manage at least one obese patient on every ED shift. Obese patients are at high risk of developing a host of medical complications including diabetes, hypertension, coronary artery disease, peripheral vascular disease, biliary disease, sleep apnea, cardiomyopathy, pulmonary embolism and depression, and are less likely compared to non-obese adults to receive timely care in the ED. Not only are these patients at higher risk for morbidity and mortality, but obesity emergency management is complicated by the patient’s altered cardiopulmonary physiology and drug metabolism. This can make their acute management much more challenging and dangerous. To help us gain a deeper understanding of the challenges of managing obese patients and elucidate a number of important differences as well as practical approaches to obesity emergency management, we welcome Dr. Andrew Sloas, the founder and creator of the fantastic pediatric EM podcast PEM ED, Dr. Richard Levitan, a world-famous airway management educator and innovator and Dr. David Barbic a prominent Canadian researcher in obesity in emergency medicine from University of British Columbia....
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...
Episode 67 Pediatric Pain Management
Pain is the most common reason for seeking health care. It accounts for 80% of ED visits. The WHO has declared that “optimal pain treatment is a human right”. As has been shown in multiple ED-based Pediatric pain management studies, Pediatric pain is all too often under-estimated and under-treated. Why does this matter? Under-estimating and under-treating pediatric pain may have not only short term detrimental effects but life-long detrimental effects as well; not to mention, screaming miserable children disturbing other patients in your ED and complaints to the hospital from parents. Whether it’s venipuncture, laceration repair, belly pain or reduction of a fracture we need to have the skills and knowledge to optimize efficient and effective pain management in all the kids we see in the ED. What are the indications for intranasal fentanyl? intranasal ketamine? Why should codeine be contra-indicated in children? How do triage-initaited pain protocols improve pediatric pain management? Which are most effective skin analgesics for venipuncture? To help you make these important pediatric pain management decisions, in this podcast we have one of the most prominent North American researchers and experts in Emergency Pediatric pain management, Dr. Samina Ali and not only the chief of McMaster Children’s ED but also the head of the division of Pediatric EM at McMaster University, Dr. Anthony Crocco.
Episode 66 Backboard and Collar Nightmares from Emergency Medicine Update Conference
In the first of our series on Highlights from North York General's Emergency Medicine Update Conference, Dr. Kylie Boothdiscusses Backboard and Collar Nightmares. The idea that backboards and c-spine collars prevent spinal cord injuries came from level 3 evidence in the 1960's and there has never been an RCT to prove this theory. In fact a Cochrane review on the topic in 2007 concluded that "the effect of pre-hospital spinal immobilisation on mortality, neurological injury, spinal stability and adverse effects in trauma patients remains uncertain" and that "the possibility that immobilisation may increase mortality and morbidity cannot be excluded". There have subsequently been several observational studies that describe increased morbidity and mortality associated with backboard and collars in a subset of patients. Dr. Booth argues that the time has long past that a major paradigm shift needs to occur toward a safer more rational use of backboards and collars in our trauma patients.
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.
Episode 64 Highlights from Whistler’s Update in EM Conference 2015 Part 2
In this Part 2 of EM Cases' Highlights from Whistler's Update in EM Conference 2015 Dr. David Carr gives you his top 5 pearls and pitfalls on ED antibiotic use including when patients with sinusitis really require antibiotics, when oral antibiotics can replace IV antibiotics, how we should be dosing Vancomycin in the ED, the newest antibiotic regimens for gonorrhea and the mortality benefit associated with antibiotic use in patients with upper GI bleeds. Dr. Chris Hicks gives you his take on immediate PCI in post-cardiac arrest patients with a presumed cardiac cause and The Modified HEART Score to safely discharge patients with low risk chest pain.
