Instrument Corrosion During Sterilization at USAF Hospital, Dyess AFB, TX

Abstract

Pitting and corrosion of surgical instruments during autoclave sterilization has been a problem for the past few years at USAF Hospital, Dyess AFB TX. The USAF Environmental Health Laboratory Kelly responded to an urgent request for analytical service in January 1975 to determine possible causes in the steam and boiler system. Field analysis indicates the problem was most likely to be free carbon dioxide in the steam lines from thermal decomposition of carbonates and bicarbonates found in the boiler feed water. The water softener and dealkalizer were put into operation and a new automatic chemical feed system ordered. A second visit to perform on-site analysis was requested and accomplished in April 1975. The autoclave was found, at that time, to be connected to a 40 psi steam line rather than the recommended 50-80 psi line. Occasional inadequate rinsing of linens during laundering has also contributed to instrument 'spotting.'
