Evaluation of antimicrobial properties in coatings for operating room surfaces

Abstract

This article highlights the crucial significance of upholding sterility in operating rooms (ORs) to minimize infection risks and uphold patient safety. Putting a spotlight on the pivotal role of antimicrobial coatings, the research delves into the examination of four frequently used coatings—polyurethane, acrylic, alkyd, and epoxy—across various surfaces within ORs. The study evaluates the antimicrobial properties of these coatings against 20 contaminant bacte- ria, uncovering diverse impacts on different strains. While these coatings may not inherently possess antimicrobial characteristics, formulations enriched with agents like 1,2-benzisothi- azol-3(2H)-one (BIT) and 2-octyl-2H-isothiazol-3-one (OIT) demonstrate active resistance against bacterial growth. The results highlight the efficacy of acrylic and epoxy coatings, spe- cifically in impeding bacterial proliferation. These findings affirm the practical utility of anti- microbial coatings in vital healthcare settings, providing valuable insights into their potential to elevate hygiene, safety, and efficiency in ORs. The study advocates for ongoing exploration of innovative coatings and antimicrobial agents, underscoring the importance of adhering to cleaning protocols and healthcare regulations for optimal effectiveness.
