Development of New Chemical Indicator for Steam Sterilization Monitoring

Comparison of a rapid readout biological indicator for steam sterilization with four conventional biological indicators and five chemical indicators.

OBJECTIVE In this study, we compare a new biological indicator that provides results within 3 hours with four conventional, 48-hour biological indicators and five chemical indicators. DESIGN Biological indicators tested included the conventional Attest 1262, Proof Plus, Assert, and Biosign, and the new Attest 1292 Rapid Readout biological indicator. Chemical indicators tested included Comply,...

Monitoring steam sterilization of surgical instruments: a dilemma.

The study of two biological indicators in monitoring "flash" sterilization demonstrated that indicator construction often leads to a false interpretation of spore survival.

Monitoring sterilization of dressings in high-vacuum pressure-steam sterilizers.

Undetected air leaks in a high-vacuum sterilizer can defeat the sterilization process. For this reason the maintenance and supervision of these sterilizers needs expert engineering care. The importance of controlling the high-vacuum sterilization process from the centre of a load rather than the chamber drain is emphasized, and a method of detecting any failure in a high-vacuum process is descr...
