Episode 90 – Low and Slow Poisoning

One of the things we need to think about whenever we see a patient who’s going low and slow with hypotension and bradycardia is an overdose. B-blockers, calcium channel blockers (CCB) and digoxin are some of the most frequently prescribed cardiovascular drugs. And inevitably we’re gonna be faced with both intentional and unintentional overdoses from these drugs in the ED. If we can recognize these overdoses early and manage them appropriately, well - we’ll save some lives...

Episode 87 – Alcohol Withdrawal and Delirium Tremens: Diagnosis and Management

Alcohol withdrawal is everywhere. We see over half a million patients in U.S. EDs for alcohol withdrawal every year. Despite these huge volumes of patients and the diagnosis of alcohol withdrawal seeming relatively straightforward, it’s actually missed more often than we’d like to admit, being confused with things like drug intoxication or sepsis. Or it’s not even on our radar when an older patient presents with delirium. What’s even more surprising is that even if we do nail the diagnosis, observational studies show that in general, alcohol withdrawal is poorly treated. So, to help you become masters of alcohol withdrawal management, our guest experts on this podcast are Dr. Bjug Borgundvaag, an ED doc and researcher with a special interest in emergency alcohol related illness and the director of Schwartz-Reismann Emergency Medicine Institute, Dr. Mel Kahan, an addictions specialist for more than 20 years who’s written hundreds of papers and books on alcohol related illness, and the medical director of the substance use service at Women’s College Hospital in Toronto, and Dr. Sara Gray, ED-intensivist at St. Michael's Hospital...

Best Case Ever 50 – Delirium Tremens

In anticipation of EM Cases Episode 87 on Alcohol Withdrawal Dr. Sara Gray describes her Best Case Ever of severe alcohol withdrawal and Delirium Tremens from Janus General. Also on this podcast Dr. Anand Swaminathan reacts to Episode 86 Emergency Management of Hyperkalemia and discusses the use of calcium in the setting of digoxin toxicity. Early recognition and treatment of Delirium Tremens - a rapid onset of severe alcohol withdrawal accompanied by delirium and autonomic instability about 3-10 days after the appearance of withdrawal symptoms - is key to preventing long term morbidity and mortality...

Episode 85 – Medical Clearance of the Psychiatric Patient

Psychiatric chief complaints comprise about 6 or 7% of all ED visits, with the numbers of psychiatric patients we see increasing every year. The ED serves as both the lifeline and the gateway to psychiatric care for millions of patients suffering from acute behavioural or psychiatric emergencies. As ED docs, besides assessing the risk of suicide and homicide, one of the most important jobs we have is to determine whether the patient’s psychiatric or behavioral emergency is the result of an organic disease process, as opposed to a psychological one. There is no standard process for this. With the main objective in mind of picking up and appropriately managing organic disease while improving flow, decreasing cost and maintaining good relationships with our psychiatry colleagues, we have Dr. Howard Ovens, Dr. Brian Steinhart and Dr. Ian Dawe discuss this controversial topic...

Episode 74 Opioid Misuse in Emergency Medicine

Pain leads to suffering. Opioid misuse leads to suffering. We strive to avoid both for our patients. On the one hand, treating pain is one of the most important things we do in emergency medicine to help our patients and we need to be aggressive in getting our patients' pain under control in a timely, effective, sustained and safe fashion. This was the emphasis 10-20 years ago after studies showed that we were poor at managing pain and our patients were suffering. On the other hand, opioid dependence, addiction, abuse and misuse are an enormous public health issue. Opioid misuse in Emergency Medicine has become a major problem in North America over the past 10 years at least partly as a reaction to the years that we were being told that we were failing at pain management. As Dr. Reuben Strayer said in his SMACC talk on the topic: “Opioid misuse explodes in our face on nearly every shift, splattering the entire department with pain and suffering, and addiction and malingering and cursing and threats and hospital security, and miosis and apnea and naloxone and cardiac arrest.” So how do we strike a balance between managing [...]

Best Case Ever 41 Opiate Misuse and Physician Compassion

Opiate misuse is everywhere. Approximately 15-20% of ED patients in the US are prescribed outpatient opiates upon discharge. In Ontario, about 10 people die accidentally from prescription opiates every week. Between 1990 and 2010, drug overdose deaths in the US increased by almost four fold, eclipsing the rate of death from motor vehicle collisions in 2009. This was driven by deaths related to prescription opiates, which now kill more people than heroin and cocaine combined. Opiates are the most prescribed class of medication in the US. In 2010, one out of every eight deaths among persons aged 25 to 34 years was opiate-related. Four out of 5 new heroin users report that their initial drug was a prescription opiate. In Ontario, three times the people died from opiate overdose than from HIV in 2011. Yet, we are expected to treat pain aggressively in the ED. Dr. Reuben Strayer, the brains behind the fantastic blog EM Updates tells his Best Case Ever, in which he realizes the importance of physician compassion in approaching the challenging drug seekers and malingerers that we manage in the ED on a regular basis. This Best Case Ever is in anticipation of an upcoming main episode in which Dr. Strayer and toxicologist Dr. David Juurlink discuss how to strike a balance between managing pain effectively and providing the seed for perpetuating a drug addiction or feeding a pre-existing drug addiction, and how we best take care of our patients who we suspect might have a drug misuse problem.

Best Case Ever 37 Neonatal Lazy Feeder

On this EM Cases Best Case Ever Dr. Anthony Crocco, the Head and the Division Head of Pediatric EM at McMaster University and Medical Director of Pediatric Emergency Medicine at Hamilton Health Sciences Hosptial, discusses an approach to the neonatal lazy feeder and why we should abandon the use of codeine in pediatrics as well as in breastfeeding mothers. The approach to the neonatal lazy feeder should be considered as an approach to altered level of awareness with a wide differential diagnosis, and there is one question that should always be asked of the neontal lazy feeder....

Best Case Ever 33: Over-correction of Hyponatremia

Rapid over-correction of Hyponatremia can have devastating consequences: for one, osmotic demyelination syndrome (ODS) can result in destruction of the pons and a locked-in state. We don't see ODS very much as it's onset is delayed and usually sets in after the patient is admitted to hospital (or worse, sent home). Nonetheless, we need to know how to manage Hyponatremia in the ED so that we prevent ODS from ever happening. In this Best Case Ever, Dr. Melanie Baimel describes the case of a young woman who came in to the ED after drinking alcohol and taking Ecstasy, wanted to leave AMA after her Hyponatremia had inadvertently been corrected too rapidly, and the conundrum that ensues. In the upcoming episode, Dr. Baimel and the first ever Internal Medicine specialist on EM Cases, Dr. Ed Etchels, discuss a rational step-wise approach to managing Hyponatremia, tailored for the EM practitioner; when you might consider giving DDAVP in the ED, the best way to correct Hyponatremia, how to manage the patient who's Hyponatremia has been corrected too quickly, and an easy approach to the differential diagnosis. Get a sneak peak at the algorithm that will be explained and reviewed in the upcoming episode...... [wpfilebase tag=file id=577 tpl=emc-play /] [wpfilebase tag=file id=578 tpl=emc-mp3 /]

Best Case Ever 26: Chloral Hydrate Poisoning and Cardiac Arrest

I met up with Mike Betzner at North York General's Update in EM Conference in Toronto. He is the medical director of Air Transport STARS air ambulance out of Calgary and an amazing speaker on the national lecturing circuit. His Best Case Ever on Chloral Hydrate poisoning & cardiac arrest describes a young man in cardiac arrest with resistant Ventricular Fibrillation and Torsades de Pointes. There is only one class of drugs that can get him back into normal sinus rhythm. Dr. Betzner describes how he recognized that this patient was suffering from Chloral Hydrate poisoning and how he saved his life with one simple intervention.
