Role of antiseptics in the prevention of surgical site infections.

BACKGROUND: Antiseptics are chemical agents used to reduce the microbial population on the surface of the skin and are used in nearly every surgical procedure today. Despite this, there are currently no definitive guidelines on surgical preoperative antisepsis that indicate a specific regimen based on demonstration of superior efficacy.

OBJECTIVE: This review serves to examine preoperative antisepsis, including cutaneous bacteriology, preoperative hair removal, preoperative decolonization, surgical attire, and the antiseptic agents themselves.

MATERIALS AND METHODS: A review of the literature on surgical antiseptics was performed.

RESULTS: Although numerous studies have demonstrated differences in bacterial colonization rates, few well-controlled investigations have demonstrated superiority of a given regimen. The alcohol-based iodophor and chlorhexidine products seem to exhibit greater efficacy than their aqueous counterparts.

CONCLUSION: More randomized controlled trials will be needed to determine if any specific regimen is most effective. At this point in time, product usage should be based on specific attributes relating to the products, such as iodophors around the eyes and/or ears to avoid irritation and aqueous-based solutions in hair bearing areas because of concern for flammability. Ultimately, it is up to the individual surgeon to tailor the optimal antiseptic regimen for their specific scope of practice.
