Silver ions in the treatment of local infections

Met Based Drugs. 1999;6(4-5):311-4. doi: 10.1155/MBD.1999.311.


A study of the use of free silver ions as an antibacterial and antifungal agent administered to infected local wounds has been conducted over the past two decades. A variety of iontophoretic techniques has been employed utilizing either pure silver wires or several types of silvered nylon fabrics as anodes in a direct current electrical circuit. A new type of silver nylon has recently been evaluated for the same use without iontophoretic current. In vitro studies of both techniques have demonstrated an effective, broad spectrum antibiotic effect including most silver-resistant strains. Over 100 cases of recalcitrant osteomyelitis have been treated with an overall success rate of approximately 65% and no evidence of argyria.
