Current standards and procedures for parametric load release are based on technologies from the 1960s, are consensus based and are often not supported by scientific evidence. In the literature, however, methods are reported which can fairly easily be implemented and improve current parametric load release for steam sterilization.
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.
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.
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.
The selected method makes steam sterilization safer, more sustainable, and more cost effective. It can be implemented by all interested end-users.
当前参数化负载释放的标准和程序基于20世纪60年代的技术,是基于共识的,且往往没有科学证据支持。然而,文献中报道了一些方法,这些方法可以相当容易地实施,并改进当前蒸汽灭菌的参数化负载释放。
实施一种改进的参数化负载释放程序,超越当前监测蒸汽灭菌过程的标准和方法。该程序的实施对所有感兴趣的最终用户都应是可行的。
使用文献中规定的蒸汽灭菌标准来定义一组蒸汽灭菌条件。对能够以参数方式评估这些条件的商用设备和方法进行了搜索。选择一种方法后,进行了现场研究。
确定了两种可用于改进蒸汽灭菌过程后参数化负载释放的设备。比较表明,一种永久安装的设备——独立于灭菌器——可测量每个蒸汽灭菌过程的温度、腔室内的蒸汽成分和时间,具有最大优势。所选方法已在51台蒸汽灭菌器上实施并进行了测试。
所选方法使蒸汽灭菌更安全、更可持续且更具成本效益。所有感兴趣的最终用户均可实施该方法。
