Episode 15 Part 2: Acute Coronary Syndromes Management

In Part 2 of this Episode on Acute Coronary Syndromes Risk Stratification & Management, the evidence for various medications for ACS, from supplemental oxygen to thrombolytics are debated, and decision making around reperfusion therapy for STEMI as well as NSTEMI are discussed. Finally, there is a discussion on risk stratification of low risk chest pain patients and all it's attendant challenges as well as disposition and follow-up decisions. Dr. Eric Letovsky, the Head of the CCFP(EM) Program at the University of Toronto, Dr. Mark Mensour & Dr. Neil Fam, an interventional cardiologist answer questions like: What is the danger of high flow oxygen in the setting of ACS? When, if ever, should we be using IV B-blockers in AMI patients? How can you predict, in the ED, who might go on to have an urgent CABG, in which case Clopidogrel is contra-indicated? Which anticoagulant is best for unstable angina, NSTEMI and STEMI - unfractionated heparin (UFH), low molecular weight heparin (LMWH), or fonduparinux? Is there currenly any role for Glycoprotein 2b3a Inhibitors in ACS in the ED? When is thrombolysis better than PCI for STEMI? When should we consider facilitated angioplasty and rescue angioplasty? Which low risk chest pain patients require an early stress test? CT coronary angiography? Stress Echo? Admission to a Coronary Decision Unit (CDU)? and many more.......

Episode 15 Part 1: Acute Coronary Syndromes Risk Stratification

In Part 1 of this Episode on Acute Coronary Syndromes Risk Stratification Dr. Eric Letovksy, Dr. Mark Mensour and Dr. Neil Fam discuss common pearls and pitfalls in assessing the patient who presents to the ED with chest pain. They review atypical presentations to look out for, what the literature says about the value of traditional and non-traditional cardiac risk factors, the diagnostic utility of recent cardiac testing, and which patients in the ED should have a cardiac work-up. Finally, in the ED work up of Acute Coronary Syndromes Risk Stratification, they highlight some valuable key points in ECG interpretation and how best to use and interpret cardiac biomarkers like troponin. Drs. Letovksy, Mensour & Fam address questions like: How useful are the traditional cardiac risk factors in predicting ACS in the ED? How does a negative recent treadmill stress test, nuclear stress test or angiogram effect the pre-test probability of ACS in the ED? What does recent evidence tell us about the assumption that patients presenting with chest pain and a presumed new LBBB will rule in for MI and require re-perfusion therapy? How can we diagnose MI in the patient with a ventricular pacemaker? What is the difference between Troponin I and Troponin T from a practical clinical perspective? Is one Troponin ever good enough to rule out MI in the patient with a normal ECG? Should we be using a 2hr delta troponin protocol? How will the new ultra-sensitive Troponins change our practice? and many more.....

Episode 14 Part 1: Migraine Headache and Subarachnoid Hemorrhage

In Part 1 of this episode on Headache Pearls & Pitfalls - Migraine Headache & Subarachnoid Hemorrhage, Dr. Anil Chopra and Dr. Stella Yiu discuss the best evidenced-based management of migraine headache in the ED including the use of dexamethasone, dopamine antagonists, the problems with narcotics and the efficacy of 'triptans'. An easy way to remember the worrisome symptoms of headache indicating a serious cause is reviewed followed by a detailed discussion of the pearls, pitfalls and controversies around the work-up of Subarachnoid Hemorrhage (SAH) in light of some exciting recent literature, including the basis for a new Canadian decision rule for SAH.

In Part 1 of this episode on the latest ACLS Guidelines, Dr. Steven Brooks and Dr. Michael Feldman review and debate what's new and what's controversial in the the 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care. Within the frameworks of Cardiocerebral Rescusitation and the 3 phase model of rescucitation (electrical, circulatory and metabolic), they discuss the importance of high quality CPR, the de-emphasis on early ventilation and the utility of continuous quantitative waveform capnography. Dr. Brooks and Dr. Feldman answer questions such as: of all the therapeutic manoeuvres we do for the cardiac arrest patient, which ones have been shown to improve survival to hospital discharge? What is the evidence for chest compression machines? What is the utility of bedside ultrasound in the cardiac arrest patient? Why is cardiac arrest survival to discharge in Seattle the best in the world? Should we be performing 'hands-on defibrillation'? and many more.....

Episode 11: Cognitive Decision Making and Medical Error

In this episode on Cognitive Decision Making & Medical Error, Dr. Doug Sinclair, CMO of St. Michael's Hospital and Dr. Chris Hicks show us that, while the ED physician's knowledge base may play a small part in predicting medical error, more important might be how we understand and reflect upon our decision-making processes, how we communicate with our staff and patients, and how we cope with the ED environment and shift work. Medical error is the 6th leading cause of death in North America, and despite huge advances in imaging technology and lab testing as well as an explosion of EM literature in recent years, the misdiagnosis rate detected through autopsy studies has not changed significantly over the past century. Studies on diagnostic error in emergency medicine have shown error rates between 1 and 12%, and it's been suggested that cognitive error, or some flaw in the decision making process (as apposed to a lack of knowledge), is present in about 95% of these cases. Dr. Sinclair and Dr. Hicks elucidate for us how to identify and understand cognitive decision making and medical error, and how we can improve our decision making, reduce medical error and optimize the care of our patients.
