Comparative Analysis of Pasteurization and Thermal Disinfection in a Washer-Disinfector: Anesthesia and Respiratory Devices

In Québec, pasteurization is the reference method for high-level thermal disinfection of anesthesia and respiratory devices. Thermal disinfection by water spray in a washer-disinfector is a method that is hardly used, however, and its effectiveness is often questioned.

This comparative assessment aims to determine to which extent the thermal-disinfection cycle in a washer-disinfector would be equivalent to pasteurization for reprocessing anesthesia and respiratory devices and to present the economic implications of using these two methods. More precisely, this technical brief describes the efficiency of both processes, perspectives in Canada and abroad regarding the two methods, and provides an acquisition and operating cost scenario for related equipments.

Conclusion

In light of the scientific literature, AETMIS finds that thermal disinfection in a washer-disinfector that complies with the Canadian and international standards is equivalent to conventional pasteurization and is effective for reprocessing anesthesia and respiratory devices.
