Hemostats were evaluated for frequency of contamination and such contamination was correlated with increasing operating room exposure time. The studies were performed under surgical conditions in operating rooms with and without laminar air flow. The study was also designed to show whether contamination of hemostats were influenced by the scrub nurse's handling. Hemostats were more frequently contaminated in the conventional operating room without laminar air flow (P less than 0.001). Handling by the scrub nurse's gloved hand statistically increased the number of contaminated hemostats (P less than 0.01). Laminar air flow reduced the frequency of contamination statistically (P less than 0.001) to a point where time and touch by a gloved hand of the scrub nurse were not important factors.
