If a pseudomonas infection is suspected in a burn wound, which topical solution is likely prescribed?

• A. Silver sulfadiazine
• B. Mafenide acetate
• C. Hydrogen peroxide
• D. Bacitracin

Answer: (B)

Mafenide acetate is particularly effective against Pseudomonas aeruginosa, which is a common pathogen found in burn wounds. This topical antimicrobial agent penetrates eschar, allowing it to reach the deeper layers of the skin where the bacteria may reside, thereby promoting healing and reducing the risk of infection. Additionally, mafenide acetate is known for its broad-spectrum activity, and its ability to inhibit the growth of a variety of bacteria makes it a suitable choice for treating burn wounds, especially when a pseudomonas infection is suspected. The other topical agents listed may have limitations in this context. For instance, silver sulfadiazine is also used but is generally considered less effective against Pseudomonas compared to mafenide acetate. Hydrogen peroxide can be cytotoxic and may impair wound healing. Bacitracin, while effective against certain gram-positive bacteria, is not sufficient for addressing the more resistant gram-negative organisms like Pseudomonas.
