A historical review of the use of silver in the treatment of burns. II. Renewed interest for silver

Abstract

In 1965, Moyer revived interest in silver nitrate solution. He concluded on the basis on in vitro and in vivo studies that a 0.5% solution represented the lowest concentration at which antibacterial action (against Staphylococcus aureus, haemolytic streptococci and generally against Pseudomonas aeruginosa and E. coli) was obtained. Mafenide acetate was introduced a short time after the reintroduction of silver nitrate, followed a few years later by silver sulphadiazine. Thus, in a short period of time three medicaments appeared on the market which represented a radical change in the topical treatment of burns. The action of silver sulphadiazine has been intensively studied. Since silver sulphadiazine does not offer sufficient protection to prevent or retard the growth of gram-negative bacteria in patients with burns covering more than 50% of body surface, Monafo introduced the combined preparation silver sulphadiazine and cerium nitrate. Although various attempts have been made to develop more effective silver compounds, so far silver sulphadiazine still remains the most widely used substance of this type.
