The field of wound care has been inundated with "active" dressings--those that deliver biologically active substances to the wound site--and much attention has been given to those containing silver. Silver is a broad-spectrum agent: it is bactericidal to a large number of Gram-positive and Gram-negative microorganisms, many aerobes and anaerobes, and several antibiotic-resistant strains. ⋯ But research findings on silver's antimicrobial efficacy are often inconclusive or contradictory. How, therefore, can clinicians decide which dressing is most appropriate for each patient? A grading system for reviewing the literature is presented.
