OBJECTIVES As ultrasonography is increasingly used in the emergency department (ED), ultrasound equipment has become a potential threat to infection control. Improperly cleaned ultrasound probes may serve as a vector for pathogens such as methicillin-resistant Staphylococcus aureus (MRSA). The primary objective of this study was to determine the prevalence(More)
Emergency medicine (EM) is in a state of evolution. In 2010, the Royal College of Physicians and Surgeons of Canada adopted a new set of training requirements for EM. These guidelines have brought about numerous changes to residency training, including increased clinical time spent in the emergency department (ED) and a more structured approach to the(More)
INTRODUCTION Starting in 2008, emergency ultrasound (EUS) was introduced as a core competency to the Royal College of Physicians and Surgeons of Canada (Royal College) emergency medicine (EM) training standards. The Royal College accredits postgraduate EM specialty training in Canada through 5-year residency programs. The objective of this study is to(More)
OBJECTIVE To evaluate whether using long-axis or short-axis view during ultrasound-guided internal jugular and subclavian central venous catheterization results in fewer skin breaks, decreased time to cannulation, and fewer posterior wall penetrations. DESIGN Prospective, randomized crossover study. SETTING Urban emergency department with approximate(More)
Retrobulbar hemorrhage is a rare complication of blunt ocular trauma. Without prompt intervention, permanent reduction in visual acuity can develop in as little as 90 minutes. We report a novel bedside ultrasound finding of conical deformation of the posterior ocular globe: the "guitar pick" sign. In our elderly patient, the ocular globe shape normalized(More)
OBJECTIVES There is a paucity of data about emergency ultrasound (EUS) training in emergency medicine (EM) residency programs accredited by the Royal College of Physicians and Surgeons of Canada (Royal College) and the College of Family Physicians of Canada (CFPC). Historically the progress of EUS in Canada has been different from that in the United States.(More)
