OBJECTIVE: To implement an improved parametric load release procedure, exceeding the current standards and methods for monitoring steam sterilization processes. Implementation of the procedure should be feasible for all interested end-users.
METHODS: The steam sterilization criteria specified in the literature were used to define a set of steam sterilization conditions. A search for commercially available devices and methods which can assess these conditions parametrically was performed. After selecting a method, a field study was carried out.
RESULTS: Two devices were identified which could be used to improve parametric load release after a steam sterilization process. A comparison showed that a permanently installed device which - independent from the sterilizer - measures the temperature, the steam composition in the chamber and the time for every steam sterilization process, offers the most advantages. The selected method has been implemented and tested on 51 steam sterilizers.
CONCLUSIONS: The selected method makes steam sterilization safer, more sustainable, and more cost effective. It can be implemented by all interested end-users.
背景:当前参数化载荷释放的标准和程序基于1960年代的技术,是基于共识的,通常没有科学证据支持。在文学中,然而,据报道,这些方法可以很容易地实施并改善蒸汽灭菌的当前参数负载释放。
方法:文献中指定的蒸汽灭菌标准用于定义一组蒸汽灭菌条件。对可以参数化评估这些条件的市售装置和方法进行了搜索。选择方法后,进行了实地研究。
结果:确定了两种装置,可用于改善蒸汽灭菌过程后的参数负荷释放。比较表明,永久安装的设备-独立于灭菌器-测量温度,室中的蒸汽成分和每个蒸汽灭菌过程的时间提供了最大的优势。所选方法已在51台蒸汽灭菌器上实施和测试。
结论:所选择的方法使蒸汽灭菌更安全,更可持续,并且更具成本效益。它可以由所有感兴趣的最终用户实现。
