A Decade of Ultrasound: CRUS 2019

This year marked the 10th anniverary for the annual Canadian Resuscitative Ultrasound (CRUS) Course at Western University. Hosted at the sophisticated CSTAR (Canadian Surgical Technologies & Advanced Robotics) facility, the CRUS course drew trainees from across Canada to teach concepts in point-of-care ultrasound for use in the acutely ill patients typically seen in the ICU, the ED or OR. Participants engaged in didactic and hands-on [...]

Case of the Week: August 26, 2019

This is 54 yo M who presented for an elective surgery. On POD # 0 he became tachycardic with subjective dyspnea and hypotension progressing into a PEA arrest. ROSC was quickly obtained with typical ACLS and he was placed on life support and transferred to the ICU for further management. A CTPA was negative, and his EKG was unremarkable with no evidence of coronary ischemia. On POD # 1 he remained hemodynamically unstable, and given very poor transthoracic windows, the decision was made to perform a TEE. Have a look at the images and Doppler information below. Is there a finding that may explain the etiology of his arrest? What would your recommendation be to the treating team?

Case of the Week: August 19, 2019

This is a 35 yo M PWID who presented with a right septic AC joint, MRSA bacteremia and hypoxic respiratory failure. He was taken to the OR for washout of his AC joint and subsequently transferred to the ICU for post-op management. A post-operative CXR showed some patchy consolidations but no obvious pleural effusions. The POCUS team was subsequently deployed. Interrogation at the costophrenic angle and PLAPS (posteroalveolar and/or pleural syndrome) point on both sides yielded the following images. What do you see and what should the next steps in management be?

Best Poster at Research Day: A-LURT’ing the People on Ultrasound

The Day Last Friday I had the amazing opportunity to present our work at the Department of Medicine Resident Research Day (take a deep breath before saying this one out loud): Acquisition and Retention of Lung Ultrasound Skills by Respiratory Therapists: a point-of-care ultrasound curriculum for respiratory therapists (and breathe). Although complimentary meals are usually enough to get hungry medical students out to [...]

Case of the Week: January 14th, 2018

A 42 year old female is admitted with ARDS and a pleural POCUS is performed. Due to difficulties identifying lung sliding, M-mode was used to evaluate for pneumothorax. Based on this image, does the patient has a pneumothorax? What is the 2D ultrasound image correlate of the vertical areas as shown by the arrows?
