Abstract

ABSTRACT: The combination of silicone oil and blood is difficult to remove from ophthalmic surgical instruments during cleaning and decontamination processes. We sought to establish the most efficient cleaning procedure for this type of contaminated instrument. We uniformly contaminated microscopic instruments made of titanium alloy and stainless steel with either blood alone or blood and silicone oil. We randomly assigned each instrument to one of four types of cleaning procedures that involved combinations of water, a multi‐enzyme detergent, or an alkaline detergent. After completing the designated cleaning procedure, a sterile processing technician used an adenosine triphosphate cleaning verification test to evaluate the cleaning efficacy. When cleaning blood‐ and silicone oil–contaminated titanium‐alloy and stainless‐steel instruments, the alkaline detergent immersion followed by a multi‐enzyme detergent ultrasonic cleaning yielded the highest cleaning effectiveness score (92.5%), which indicates this was the most effective of the four cleaning procedures that we tested.
