目的比较不同类型的灭菌过程验证装置(PCD)在大型预真空压力蒸汽灭菌过程中的监测作用。方法选用3种PCD同时在预真空蒸汽灭菌过程中进行灭菌监测,通过观察100锅次,对3种不同PCD的监测结果进行比较。结果自制标准PCD与绿色管腔型PCD的监测结果之间没有差异,但橙色管腔型PCD的监测结果与自制标准PCD以及绿色管腔型PCD的监测结果均存在显著性差异(P<0.05)。结论在临床工作中,应当按照不同的灭菌物品类型选择与其对应的PCD进行监测,绿色管腔型PCD能监测到管腔器械的内部,同时具有操作简便,敏感性稳定以及结果评价简便的优点,值得推广使用。
Objective To compare the different types of sterilization process validation device (PCD) in the large pre-vacuum pressure steam sterilization process monitoring. Methods Three kinds of PCDs were used for sterilization monitoring in the process of pre-vacuum steam sterilization at the same time. The monitoring results of three different PCDs were compared by observing 100 pots. Results There was no difference between the results of PCD and green PCD. However, there was a significant difference (P <0.05) between the monitoring results of orange PCD and those of PCD and PCD. . Conclusions In clinical work, PCDs should be selected according to the different types of sterilization articles. The green cavity PCD can monitor the interior of the cavity instruments, and has the advantages of simple operation, stable sensitivity and simple evaluation of the results , It is worth to promote use.
