An antimicrobial film forming surgical site preparation composition includes a film forming material and an antimicrobial agent soluble in a fugitive solvent. The composition when applied to the skin surface forms a substantially water insoluble, substantially tack-free flexible film adherent to the skin surface. The film is capable of releasably retaining the antimicrobial agent to substantially inhibit microbial growth on the skin surface. The film releases sufficient antimicrobial agent to substantially eliminate the microorganisms normally present on the skin surface to prepare the surface for the procedure and continues to release the antimicrobial agent during the procedure and subsequent wound healing. The composition can be easily washed from fabric and does not stain the fabric even where the fabric is treated with chlorine bleach. In addition, a smooth continuous film is formed without the use of a separate plasticizer.

Composition servant à préparer le champ opératoire en créant une pellicule antimicrobienne et comprenant un matériau permettant de créer cette pellicule antimicrobienne, ainsi qu'un agent antimicrobien soluble dans un solvant fugitif. Cette composition, quand on l'applique à la surface de la peau, constitue sur cette dernière une pellicule souple pratiquement insoluble dans l'eau et pratiquement non adhésive. Cette pellicule est capable de retenir, de manière à le dégager, l'agent antimicrobien afin d'inhiber sensiblement la croissance microbienne sur la surface de la peau. Cette pellicule dégage une quantité suffisante d'agent microbien pour éliminer les micro-organismes normalement présents sur la surface de la peau, afin de préparer cette dernière pour l'intervention chirurgicale, et continue à dégager cet agent antimicrobien pendant l'intervention et la guérison ultérieure de la blessure. On peut enlever sans difficultés la composition depuis un tissu en lavant celui-ci, qu'elle ne tache pas même si le tissu a été traité au blanc de lessive au chlore. De plus, une pellicule lisse continue se crée sans utiliser de plastifiant séparé.
