Point of Care Ultrasound Literature Primer: Key Papers on Focused Assessment With Sonography in Trauma (FAST) and Extended FAST.

Objective The objective of this study is to identify the top five most influential papers published on focused assessment with sonography in trauma (FAST) and the top five most influential papers on the extended FAST (E-FAST) in adult patients. Methods An expert panel was recruited from the Canadian Association of Emergency Physicians (CAEP) Emergency Ultrasound Committee and the Canadian Ultrasound Fellowship Collaborative. These experts are ultrasound fellowship-trained or equivalent, are involved with point-of-care ultrasound (POCUS) research and scholarship, and are leaders in both the POCUS program at their local site and within the national Canadian POCUS community.

An unusual cause of chest pain: Exercise induced sternal fracture in a young man.

This case report describes a 26-year-old male who presented with anterior chest pain after weightlifting at the gym. Point-of-care ultrasound was used to diagnose a sternal fracture, which was then confirmed on CT scan. This rare mechanism of sports related sternal fracture is discussed, as well as a review of the literature.

Prehospital Nitroglycerin Safety in Inferior ST Elevation Myocardial Infarction.

Patients with inferior ST elevation myocardial infarction (STEMI), associated with right ventricular infarction, are thought to be at higher risk of developing hypotension when administered nitroglycerin (NTG). However, current basic life support (BLS) protocols do not differentiate location of STEMI prior to NTG administration. We sought to determine if NTG administration is more likely to be associated with hypotension (systolic blood pressure < 90 mmHg) in inferior STEMI compared to non-inferior STEMI.

The ABCD2 score: a poor predictor of stroke risk in the emergency department.

Clinical Question: In patients presenting with transient ischemic attack in the emergency department, what is the accuracy of the ABCD2 score for predicting stroke?

Article Chosen: Perry JJ, Sharma M, Sivilotti ML, et al. Prospective validation of the ABCD2 score for patients in the emergency department with TIA. CMAJ 2011;183:1137-45.
