摘　　要：目的分析压力蒸气灭菌包内化学指示卡不同放置位置的变色情况与灭菌效果。方法2009年1月至2011年1月选取需要灭菌的物品包168个，按照随机的原则逐一编号均分为A、B2组各84个，分别将化学指示卡放在不同的物品包内不同的位置。观察2组化学指示卡变色情况和细菌学检测的合格率。结果A组84个化学指示卡中有9个出现变色不均匀现象，发生率为10．71％，高于B组的发生率。A组84个物品包灭菌后细菌学检测不合格数量为2个，不合格率为2．38％，虽高于B组的细菌学检测不合格率1．19％，但二者比较差异无统计学意义。结论化学指示卡可以真实地反映物品包内的灭菌效果，但是放置位置不同，会出现不同的显示结果。在两层包装之间放置指示卡变色均匀，既可以为临床医生判读灭菌效果提供有力证据，又可以为消毒供应室避免不必要的经济浪费，值得在消毒供应室推广。Objective To observe the discoloration of chemical indicator cards in different positions in pressure steam sterilization bags and sterilization effect. Methods From January 2009 to January 2011, 168 packages needing sterilization were divided into group A and group B randomly with 84 packages in each. We put chemical indicator cards on different positions in the packages. Then discoloration of chem- ical indicator cards and the qualified rate of bacteriology detection were observed. Results There were 9 cases of uneven discoloration in group A, and the incidence rate was 10.71%, higher than group B. The un- qualified rate of bacteriology detection in group A was 2.38%, higher than group B（1.19%）, but the differ- ence was not statistically significant. Conclusions Chemical indicator cards could reflect the effect of sterilization, but placing them in different positions can appear different results. The chemical indicator cards that placed between the two packing layer could provide powerful evidence for sterilization effects for clinicians, and avoid unnecessary economic waste in Sterilization and Supply Center, which is worthy of be- ing widely used in Sterilization and Supply Center.
