Mnemonic Monday: AEIOU – Indications for Dialysis in Patients with Acute Kidney Injury

1

By Michael Spinner

Acute kidney injury (AKI) is a common problem among hospitalized patients with numerous etiologies. Common causes include volume depletion or renal hypoperfusion (prerenal), ATN from ischemia or nephrotoxins (intrinsic), and urinary obstruction (postrenal). For all of these etiologies, the final common pathway is an acute decline in the GFR, resulting in elevation of serum BUN and creatinine and often a decline in urine output. In most cases, patients with AKI recover with treatment of the underlying cause (e.g. IV fluids for prerenal azotemia). In some cases, however, prompt treatment with dialysis is warranted. Use the mnemonic below to remember the indications for dialysis in patients with AKI:

IMGs are often lulled into a false sense of security by the format of this exam, which stresses absolute fundamentals. However, in my opinion, and based on my experience, the Step 2 CS is perhaps the single most important exam in the current residency application process.

By Molly Lewis

On the Road Again - Away Rotations!During the first several months of the 4th year of med school, many students pack their bags, pre-pay their rent, and fly off to a new med school to spend four weeks on an away rotation. Sean’s post about DO audition rotations has some quality advice that applies to MD away rotations, but here is a bit more advice from my perspective. (Caveat: I only know the world of ortho away rotations. I think my advice will help with other specialties, too, but just keep that it mind).
