The antimicrobial effectiveness of operative-site preparative agents

Abstract

Ieved a significant reduction (p less than or equal to 0.001) of indigenous skin microflora compared with the pre-scrub level in both the post-scrub and the postoperative cultures. Two iodophors, when applied as sprays, demonstrated excellent bactericidal action, were less time-consuming and easier to use than the compounds that were applied as scrubs, and did not alter the low (0.42 per cent) infection rate that we have recorded over a period of four years. Eight wound preparative agents (one triclosan compound, one hexachlorophene compound, and six iodophors) were evaluated under actual operating-room conditions for efficacy in de-germing the operative site prior to the performance of 310 total hip arthroplasties. All of the preparations tested achieved a significant reduction (p less than or equal to 0.001) of indigenous skin microflora compared with the pre-scrub level in both the post-scrub and the postoperative cultures. Two iodophors, when applied as sprays, demonstrated excellent bactericidal action, were less time-consuming and easier to use than the compounds that were applied as scrubs, and did not alter the low (0.42 per cent) infection rate that we have recorded over a period of four years.
