Effects of Non-Condensable Gases (NCGs) on Steam Sterilisation Processes

“A study conducted by Prof. von Eiff of University of Münster in hospitals in North Rhine Westphalia and Lower Saxony revealed that, in particular, 40% of hollow instruments released for use were not sterile (4). One reason for such problems is that the classic biological and/or well-integrated chemical indicators can attest to the sterility of supplies only at those locations at which they are positioned. But in general these indicators cannot be placed at those sites within the instrument which are most difficult to access, hence the established practice of using such indicators is not suitable for providing insights into the sterility of lumened devices.”
