Topical Antimicrobials


- See:
      - wound management
      - pressure irrigation

- Discussion:
    - skin prep agents:
           - iodophors;
           - chlorohexidine;
    - topical agents administered should be effective against Pen-Res Staph aureus and epidermidis, as well, as gram neg (E.coli, Klebsiella),
           and Proteus (gm neg accounting for upto 1/3 of total joint infections);
    - neomycin
    - bacitracin
           - in concentrations as low as 50,000 units/L and polymyxin in concentrations as low as 50 mg/liter sterilized all cultures but S.epidermidis
                    and Proteus species; - use 50 units per ml;
    - triple ATB:
           - lowest concentrations of a triple ATB solution that eradicated all organisms were 5% neomycin (5-10 mg/ml), bacitracin 25,000 units/liter, and
                      polymyxin 25 mg/liter (0.05 mg per ml)
           - these agents should be allowed to remain in the wound for atleast one minute before their removal;
    - mafenide acetate tested at a clinical concentration of 10% resulted in average cell survival of 73 % of the population.
    - mupirocin
           - Decrease in infections with the introduction of mupirocin cream at the peritoneal dialysis catheter exit site.
