Thoracentesis%20SRMA

Ultrasound guidance compared to anatomic landmark approach for thoracentesis: a systematic review and meta-analysis
Am J Emerg Med 2025

Our former fellows Rukaiyah Lakkadghatwala and Alex Wilson performed a systematic review and meta-analysis of ultrasound guidance compared to anatomical landmark technique for thoracentesis. They found that ultrasound guidance trended towards increased success rates and lower complication rates. Their paper is freely accessible as an open access publication.

POCUS%20Lit%20Aorta%20and%20DVT

POCUS literature primer: key papers on aorta and deep vein thrombosis POCUS
CJEM 2025

The POCUS literature primer series continues with a paper focusing on the top 5 most influential papers on aorta POCUS and DVT POCUS. You can find this in the April issue of the Canadian Journal of Emergency Medicine. The 15-member expert panel used a modified Delphi process and 3 rounds of sequential surveys to create this shortlist.

Emerg%20Med%20Clinics%20GU%20Ultrasound

Genitourinary ultrasound
Emerg Med Clin 2024

An Emergency Medicine Clinics review paper on the use of POCUS for genitourinary complaints. This is an update on Vicki Noble’s classic “Renal Ultrasound” paper in Emergency Medicine Clinics from 2004. We provide an update on the evidence supporting the use of POCUS for approaching GU complaints, as well as clinical algorithms for integrating its use in suspected renal colic and acute scrotal pain.

Use of point-of-care ultrasound in rural British Columbia: Scale, training, and barriers
Can Fam Physician 2024

A survey study describing the demographcis, locations, education and training, and attitudes of practitioners using POCUS in rural British Columbia. While the vast majority of emergency department-based practitioners had access to POCUS, over half of respondents are using it in the clinic setting. However, there are still considerable barriers, especialy lack of training.
