Management of critically ill patients in austere environments is a logistic challenge. Availability of oxygen cylinders for the mechanically ventilated patient may be difficult in such a context. A solution is to use a ventilator able to function with an oxygen concentrator. ⋯ The ability of an oxygen concentrator to deliver high FiO2 when used with a turbine ventilator makes this method of oxygen delivery a viable alternative to cylinders in austere environments when used with a turbine ventilator. However, FiO2 has to be monitored continuously because delivered FiO2 decreases when minute ventilation is increased.

Observational Study
Medical Student Education in Emergency Medicine: Do Students Meet the National Standards for Clinical Encounters of Selected Core Conditions?
Establishing a core curriculum for undergraduate Emergency Medicine (EM) education is crucial to development of the specialty. The Clerkship Directors in Emergency Medicine (CDEM) National Curriculum Task Force recommended that all students in a 4(th)-year EM clerkship be exposed to 10 emergent clinical conditions. ⋯ Most students do not encounter all 10 conditions during patient encounters throughout a 4-week EM rotation, although most have exposure to at least eight. Certain conditions are far less likely than others to be encountered, and may need to be taught in a nonclinical setting.

Randomized Controlled Trial
Injectable Lidocaine Provides Similar Analgesia Compared to Transdermal Lidocaine/Tetracaine Patch for the Incision and Drainage of Skin Abscesses: A Randomized, Controlled Trial.
Local anesthesia used for incision and drainage of abscesses is known to be painful. ⋯ Local injection of lidocaine provided clinically similar analgesia compared to the lidocaine/tetracaine patch during I&D of skin abscesses in the ED. Pain at presentation and after the procedure was similar in both groups. Emergency physicians should continue to use a local injected anesthetic for I&D of skin abscesses until a less painful alternative is identified.

Orbital injury secondary to petroleum-based products is rare. We report the first case, to our knowledge, of a combined compressed air and chemical orbital injury, which mimicked necrotizing fasciitis. ⋯ A 58-year-old man was repairing his motorcycle engine when a piston inadvertently fired, discharging compressed air and petroleum-based carburetor cleaner into his left eye. He developed surgical emphysema, skin necrosis, and a chemical cellulitis, causing an orbital compartment syndrome. He was treated initially with antibiotics and subsequently with intravenous steroid and orbital decompression surgery. There was almost complete recovery by 4 weeks postsurgery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Petroleum-based products can cause severe skin irritation and necrosis. Compressed air injury can cause surgical emphysema. When these two mechanisms of injury are combined, the resulting orbitopathy and skin necrosis can mimic necrotizing fasciitis and cause diagnostic confusion. A favorable outcome is achievable with aggressive timely management.
