Abstract

Reducing the quantitative level of bacterial contamination in an open, acute or chronic, soft tissue wound below the critical level of 10(5) bacteria per gram of viable tissue is essential to delayed primary closure. First step in the management of the contaminated or infected wound is accurate local debridement, preferably with pulsating jet irrigation. Topical antibacterial agents, specifically silver sulfadiazine cream, are then usefully employed to reduce the bacterial count. Contrary to systemic antibiotics, these agents penetrate adequately into the open, granulating wound with a direct bacteriostatic or bactericidal action on a wide spectrum of gram positive and negative organisms, without the effect of local tissue injury typical of topical antiseptics. The use of topical antibacterials, traditionally confined to the treatment of the burn wound, the open "difficult" wound for excellence where control of local infection is first priority, provides a rapid local reduction of the bacterial level and paves the way to the final goal of primary delayed closure of the wound, either direct or with the use of grafts or local, distant, or free flaps.
