Disinfection of Cystoscopes by Pasteurization

Disinfection of Cystoscopes by Subatmospheric Steam and Steam and Formaldehyde at 80 ° C

The various methods of disinfection at present used for endoscopic instruments include immersion in an antiseptic solution (Miller et al., 1960), pasteurization in water (Francis, 1959), exposure to formalin vapour in a cabinet, and exposure to ethylene oxide. Though certain endoscopes are able to withstand autoclaving, this method cannot be used for all parts of the endoscope or for children's...

A microbiological evaluation of level of disinfection for flexible cystoscopes protected by disposable endosheaths

BACKGROUND Flexible cystoscopy is used in urological outpatient departments for diagnostic cystoscopy of bladder cancer and requires a high-level disinfection between each patient. The purpose of this study was to make a microbiological post disinfection efficacy assessment of flexible cystoscopes (FC) using disposable sterile endosheaths. METHODS One hundred endosheaths underwent a leak-test...

Pasteurization

Pasteurization is still in its infancy in India, the vast majority of the people being content with boiled milk which, in spite of its keeping qualities and distinct flavour, suffers from the disadvantage of having lost some of its nutritive value owing to excessive heating. In cities, where the milk supply is at present in very unsatisfactory state, the demand for pasteurized milk is growing, ...

Cold Pasteurization of Food by Irradiation

Food irradiation is a preservation process of exposing foods to high-energy rays to improve product safety and shelf life. Red meats, poultry, potatoes, onions, spices, seasonings, fresh fruits and vegetables may be irradiated to prevent growth of food poisoning bacteria, eliminate parasites, or delay ripening and spoilage. Also, irradiation could be used to replace chemical preservatives in fo...
