What's red, fluctuant, and painful? An abscess of course. But what if it's not just a simple abscess? Can ultrasound help us out clinically? Read on as Dr. Shaw answers these questions and more in this month's Ultrasound Case of the Month!Read More
In March 2015, Dr. Renne did a Grand Rounds lecture on soft tissue neck radiographs, which offers a great review of normal anatomy and systematic approach to reading films (“CHESS”). Yet, in my small, informal (not scientific at all) poll of some of our residents, none had ever ordered a soft tissue neck film. Are soft tissue neck radiographs useful? You be the judge.Read More
Evidence-Based Emergency Medicine: Vent Management with Drs. Axelson & Scupp
The term Acute Lung Injury (ALI) is being phased out and instead Acute Respiratory Distress Syndrome (ARDS) is now graded mild, moderate, and severe depending on the PaO2:FiO2 ratio
The median onset of ARDS after presentation to the ED was 2 day but could be anywhere from 5 hours to 5 days
ARDS Net was a foundational trial in ventilator management and was a triall of tidal volume and plateau pressures. The primary end point, mortality, was reduced by >20% when folks were on a low TV (6cc/kg) and lower PP (25-30 mm Hg).Read More
The soft-tissue neck radiograph can be an extremely useful tool in a variety of clinical situations. These include: epiglottitis, croup, retropharyngeal abscesses, and localization of airway foreign bodies.
However, like any diagnostic tool, the soft tissue neck x-ray’s usefulness depends on knowledge of the relevant anatomy — particularly the normal size and appearance of various airway structures — as well as a systematic approach to each radiograph. We will discuss both the anatomy and radiographic approach in this blog post.Read More
