Surgical instrument trays are wrapped for sterilization, and these wraps are inspected by operating room personnel for defects before using the instruments. In this study, we intentionally damaged wraps, and these wraps were evaluated by operating room personnel. Examiners correctly identified a wrapper's sterile integrity with an overall 56.1% accuracy, with correct identification of 67.2% for defects between 2 and 5 cm. However, studies have shown bacterial contamination through defects as small as 1.1 mm. This study suggests that the current method for assessing sterility is inadequate.
手术器械托盘经过包裹后进行灭菌，在使用器械之前，手术室人员会检查这些包裹是否有缺陷。在这项研究中，我们故意损坏了包裹，然后由手术室人员对这些包裹进行评估。检查人员的总体正确识别率为 56.1%，对于 2 至 5 厘米之间的缺陷，正确识别率为 67.2%，能够正确识别包裹的无菌完整性。然而，研究表明，即使是 1.1 毫米大小的缺陷也会导致细菌污染。这项研究表明，目前评估无菌状态的方法并不完善。
