This paper presents the results of a study to explore the effects of pre-wetting of the inner and outer surface of surgical gown materials on their resistance to subsequent penetration. Two gown fabrics currently in common use, one disposable and one reusable, were tested for liquid penetration following standard procedures specified for categorizing surgical gown protection levels. Synthetic blood, simulated human perspiration, and isopropyl alcohols were used as challenge liquids. Significant results from independent-samples t-test analysis indicated that the dry-wet condition of surgical gown fabrics is a significant factor in barrier efficacy. Protection of the wearer may be compromised by gown fabric wetness from blood or other liquids in the surgical environment or by the wearer's perspiration. Protocols for replacement of surgical gowns may need to take these factors into account.
