Let's see what was on my list....
- vasopressors, does making the number look better actually improve outcomes?
- do any of our commonly prescribed muscle relaxants actually work?
- advantages/disadvantages to intraosseus lines
- do abscesses need packing? or antibiotics?
- does cellulitis without an abscess really need MRSA coverage?
- are massive transfusion protocols necessary?
- steroids in spinal cord trauma (something our neurosurgeons frequently do that's way behind the times)
- tpa
- digital rectal examination (in trauma, in undifferentiated abdominal pain)
- early goal-directed therapy for sepsis
- CT contrast risks
- pitfalls of CT coronary angiography (too many false positives)
- efficacy of in-house rapid response teams (function mostly just to move people to the ICU to die)
- utility of lidocaine in head injury (no)
- "defasciculating dose" in intubation
- sux vs roc (why ever use sux for RSI?)
- etomidate vs anything (versed, ketamine) for RSI in sepsis
- utility (false positives, change in treatment) of urine/blood/wound cultures
- "seatbelt signs" and who to scan
- absorbable vs nonabsorbable suture
- any element of acls
- is droperidol's black box warranted
- does laceration repair need to be "sterile"
- why would you ever use ketorolac vs ibuprofen
And many more.
www.thennt.com has some more ideas that are a little bit more farfetched - like the efficacy of heparins in NSTEMI, which I think might be validated a little bit by the retrospective subgroup analysis from the ACUITY trial where it didn't matter how soon you started heparin for NSTEMI in terms of preventing additional events. I.e., if it doesn't matter how quickly you start a treatment, then maybe the treatment isn't doing anything....
