Concerning my question about antibiotics:
Routine/general use of antibiotics pre-op on patients that do not have a documented medical need ( ex. hx of Rheumatic fever, mitral valve prolapse WITH regurg., recent joint replacement, Prosthetic heart valve) is not indicated. To me, that would be wasting precious and limited quantity meds. You are also putting the patient at an unnecessary risk for an allergic reaction.
The reasoning behind not needing Ab's post-op after standard extractions... you are taking the etiology or cause of the infection out of the patient when you remove the tooth. The normal immune response can then handle the residual bacteria left in the socket.

Now, if they are showing systemic signs of infection (fever, malaise), then I would agree with Ab useage. Also, a clinically large fluctuant or any size cellulitis infection would also dictate use of Ab, IMO.
Note on premed- If I was working on a fellow US soldier. If I had the time, I might pre-med the patient with 800mg of IBU 2 hours before. That way, when the anesthesia wears off , the med is in place. It also cuts down on postop inflammation IMO. That is not a "guideline", just my personal choice though.
