Antibacterial effects on dry-fast and traditional water-based surgical scrubbing methods: a two-time points experimental study.

This study determined the in-use effects of dry-fast and traditional hand-washing surgical scrubs among operating room staff members. This is a static group comparison study with purposive sampling. A total of 156 staff members were recruited in an operating room in a medical center located in southern Taiwan. The participants were divided into traditional and dry-fast hand-washing groups. Microbial counts were measured right after the two groups finished surgical scrubbing and at the completion of surgery. The results showed that the use of dry-fast antisepsis has a better persistent effect (P = 0.001), more nurses chose dry-fast antisepsis than surgeons (P = 0.012), and the post-operation number of colonies for nurses was significantly higher than that for surgeons (P = 0.003). Operating room nurses are long-term and frequent users of antibacterial agents, and their requirement of skin protection is higher. The dry-fast technique has the advantage of being less irritating to the skin and less time consuming; therefore, brush-free and dry-fast antisepsis is recommended.
