Welcome to The Pearl Log — where post-shift wisdom surfaces, one shiny clinical take at a time. Some pearls are fresh, some are rough, all are found under pressure.

Pregnancy Ultrasound Potpourri
First trimester bleeding is one of the highest value POCUS moments in the ED. A quick transabdominal scan that shows a clear intrauterine pregnancy lets you safely discharge most patients in minutes. If the IUP is not obvious, move to transvaginal imaging to nail down the diagnosis and guide next steps.
Ultrasound for Pneumoperitoneum and C-Collar Clearance
First, pneumoperitoneum on ultrasound—look for the “enhanced peritoneal stripe” and those peritoneal A-lines in the least dependent area (epigastrium or over the liver). A linear probe can help spot the air. Second, C-spine clearance after a negative high-quality CT—Trauma EAST says yes, even in obtunded patients. CT alone has an almost 100% negative predictive value, and prolonged collars can do more harm than good.
