Surgical gowns and drapes as aseptic barriers

The use of surgical gowns and drapes has become the standard of practice in the arena of surgical aseptic technique. Because of myriad of materials, both woven and nonwoven, are currently available, users are faced with the difficult task of choosing a bacteriologic barrier material that is effective, safe, and economical. Although recommendations are available for general selection and use of barrier materials, no specific guidelines exist to assist the user in evaluating the important features of barriers. In addition, standards are lacking for safety characteristics such as flammability and fiber content. The infection control practitioner needs to be aware of the issues surrounding surgical barrier materials to be able to put the infection control merits of these materials in their proper perspective.
