In implant surgery air and surface contamination have become important factors in post-operative wound infection. We established the rate of contamination of surgical gown packs and found that dropping gloves onto the open gown pack prior to scrubbing had no effect on it. Ninety-six contact plates were used for this study, which was carried out during clean orthopaedic operations in one operating room. The overall rate of contamination was 65%. Most of the contaminants were skin commensals. The rate of contamination was 67% when gloves were dropped onto the gown pack compared with 63% when opened and presented to the scrubbed and gowned theatre staff. However this difference was statistically not significant. The high rate of contamination was probably due to the gown packs having been left opened for too long. This delay arose because each gown pack had three gowns and would have been avoided if single gown packs had been used.
在植入手术中，空气和表面污染已成为术后伤口感染的重要因素。我们确定了手术衣包装的污染率，发现术前将手套掉落在打开的手术衣包装上对其没有影响。本研究使用了96个接触平板，研究在一个手术室进行的清洁骨科手术期间开展。总体污染率为65%。大多数污染物是皮肤共生菌。将手套掉落在手术衣包装上时的污染率为67%，而打开并递给已刷手和穿手术衣的手术室工作人员时的污染率为63%。然而，这种差异在统计学上并不显著。高污染率可能是由于手术衣包装打开时间过长。出现这种延迟是因为每个手术衣包装有三件手术衣，如果使用单件手术衣包装本可避免这种情况。
