Sensitivity of Bedside Ultrasound and Supine Anteroposterior Chest Radiographs for the Identification of Pneumothorax After Blunt Trauma

Landmark Series
Methodology Score: 4/5                 
Usefulness Score: 4/5

Wilkerson RG, Stone MB.
Acad Emerg Med. 2010 Jan;17(1):11-7.

This evidence-based literature review of four prospective observational studies identified that bedside ultrasound had excellent sensitivity (86-98%) especially compared to supine AP xray (28-75%) for identifying pneumothorax after blunt trauma.  The group discussed that this was a practice changing article when it was published in 2010, expanding the applications of bedside ultrasound in blunt trauma.

Epi lesson: PICOS
When reviewing systematic literature reviews, pay attention to how the research question is phrased. High quality studies will follow the PRISMA guidelines’ suggestion to use the PICOS (participants, interventions, comparisons, outcomes, study design) format. A precise research question will guide study selection and should also dictate how table 1 summarizes the included studies.  Having these details will also assist the reader in evaluating the included studies for generalizability and clinical heterogeneity.

Tips for Success in your Emergency Medicine Rotation

Our wonderful medical students are preparing to start their first clinical rotations. With this in mind here are some of the top tips for success in your EM rotation
1)Be On Time – show up to your shifts on time, better yet 5 minutes early.That first impression is immensely important.
2)Introduce yourself to the team - “Hi my name is John Doe, I am the medical student on shift today” introduce yourself to the attending, residents, nurses, etc.You will be called on a lot more to help when there is something interesting going on if they know your name.
3)Be goal-oriented – have a goal for each shift, whether it’s a procedure or a type of presentation to see.
4)Don’t just stand there, do something – whenever there is a trauma or code, come to the bedside.Get gowned up for traumas and pay attention.Help with things that are within your scope of practice: chest compressions, moving patient, cardioversion
5)Don’t just stand there, do nothing – there are times in medicine when the best thing to d…

The Canadian Syncope Risk Score

Guest post by Dr. Venkatesh Thiruganasambandamoorthy.
Syncope is an commonly encountered problem in Emergency Medicine, with the potential for significant morbidity and mortality to patients. Unfortunately, to date, there have not been any reliable decision tools or instruments to help us in our assessment of the syncope patient.  This week, Venkatesh Thiruganasambandamoorthy and colleagues at the Ottawa Hospital have published an new Canadian Syncope Risk Score to identify patients at risk of serious adverse events, published in CMAJ.1 Here, Dr. Venk helps provides some further insight and potential utilization of the risk score, he may also be heard discussing this rule on the March edition of Canadian EMRAP.


BackgroundSyncope constitutes 1% of Emergency Department (ED) visits, and approximately 10% of these patients will have serious underlying conditions causing syncope (arrhythmia, MI, serious structural heart disease, pulmonary embolism, subarachnoid or severe hemorrhage). Alarmin…

2014 Canadian Guidelines for AF Management: Part 1: Introduction and CCS “CHADS-65” Algorithm

by Ian Stiell MD @EMO_Daddy














In this and subsequent postings we will discuss the latest recommendations for ED management of atrial fibrillation (AF) as presented in the newly published 2014 Focused Update of the Canadian Cardiovascular Society Guidelines for the Management of Atrial Fibrillation. The Guidelines PDF can be downloaded from the CCS website at 2014 Canadian Cardiovascular Society Guidelines for the Management of Atrial Fibrillation
The 2014 Focused Update uses the GRADE system of evidence evaluation as was the case in the comprehensive 2010 AF Guidelines and the 2012 Update. The CCS AF Guidelines Panel is comprised of Canadian cardiologists plus physicians from internal medicine, family medicine, neurology, and emergency medicine. This 2014 Update provides evidence review and recommendations for 8 aspects of AF care, including ED Management (written by myself and Dr. Laurent Macle of the Montreal Heart Institute). The 2014 Update focuses on advances in oral anticoagulant (O…
