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.
对止血钳的污染频率进行了评估，并将这种污染与手术室暴露时间的增加相关联。研究在有和没有层流空气的手术室的手术条件下进行。该研究还旨在表明止血钳的污染是否受洗手护士操作的影响。在没有层流空气的传统手术室中，止血钳的污染更为频繁（P小于0.001）。洗手护士戴手套的手进行操作在统计学上增加了被污染止血钳的数量（P小于0.01）。层流空气在统计学上降低了污染频率（P小于0.001），达到了洗手护士戴手套的手的操作时间和接触不再是重要因素的程度。
