Mycobacterium chimaera infections have mainly been associated with the heater-cooler unit (HCU) and, ultimately, linked to contaminated aerosols in the operation room. The contamination status of HCUs seems to be influenced by the maintenance, therefore, according to the manufacturer’s recommendations, peracetic acid (Puristeril) was introduced to increase HCU cleaning and disinfection protocol maintenance. Aerosol dispersion from Puristeril during maintenance can cause adverse effects to nearby workers. We aim to describe our technique to reduce the impact of Puristeril on operating room staff and to limit dispersion of its aerosol in the environment by performing the cleaning procedure through a closed circuit.
