Which dressing may provide antimicrobial effect but requires caution with sensitivities in infected wounds?

• A. Gauze
• B. Hydrogel
• C. Silver-impregnated dressing
• D. Transparent film

Answer: (C)

Silver-impregnated dressings provide antimicrobial action by releasing silver ions that disrupt microbial cell membranes and cellular processes, helping to lower bioburden in infected wounds and support healing. They are especially useful when infection is present or risk of infection is high, as they offer broad-spectrum activity without requiring antibiotic use. At the same time, they require caution because some patients have sensitivities or allergies to silver, which can cause dermatitis or local irritation. Before using, assess the patient’s history for metal sensitivities and monitor the wound for signs of intolerance, such as increasing redness, itching, or rash. Use them for an appropriate, limited duration and reassess; they aren’t necessary for every wound and may not be ideal when there is a dry wound or when cost or cytotoxic concerns are factors. Gauze, hydrogel, and transparent film do not inherently provide antimicrobial activity, so they don’t meet the requirement of antimicrobial effect with a need for sensitivity caution in infected wounds as precisely as silver-impregnated dressings.
