Persistent contamination of heater–cooler units for extracorporeal circulation cured by chlorhexidine–alcohol in water tanks [PDF]

Journal of Hospital Infection, 2018
Recently, surgical site infections due to non-tuberculous mycobacteria (NTM) have been linked to heater-cooler unit contamination. The European Centre for Disease Prevention and Control and manufacturers now recommend the use of hydrogen peroxide in filtered water to fill heater-cooler unit tanks. After implementation of these measures in our hospital,

The Global Outbreak of M. chimaera Infection Following Cardiac Surgery: Another Piece of the Puzzle [PDF]

Pathogens
Invasive cases of Mycobacterium chimaera have been found in Europe, and beyond, and have been associated with the use of heater–cooler units necessary to regulate the temperature of blood in extracorporeal circulation during cardiac surgery, mostly due ...

The Heater–Cooler Unit—A Conceivable Source of Infection

The Journal of ExtraCorporeal Technology, 2002
Even drinking water is contaminated with pathogenic microorganisms. This does not necessarily pose a risk for healthy individuals, but it may result in serious consequences in people with impaired immune systems. This is particularly valid if drinking water is used for medical purposes.

Biofilm formation by the global outbreak strain of Mycobacterium chimaera results in significantly reduced efficacy of standard disinfectants [PDF]

BMC Microbiology
Background In 2013, a global outbreak of Mycobacterium chimaera infections due to contaminated heater-cooler units emerged. This ongoing problem has highlighted the question of whether disinfection recommendations for medical devices containing water ...

Microbiological problems and biofilms associated with Mycobacterium chimaera in heater–cooler units used for cardiopulmonary bypass [PDF]

Journal of Hospital Infection, 2017
The role of heater-cooler units (HCUs) in the transmission of Mycobacterium chimaera during open heart surgery has been recognized since 2013. Subsequent investigations uncovered a remarkable global outbreak reflecting the wide distribution of implicated devices.

Transfer Irreversibilities in the Lenoir Cycle: FTT Design Criteria with $\mathit{\epsilon }\mathbf{-}\mathit{NTU}$ [PDF]

Entropy
This work extends the steady flow Lenoir cycle within finite-time thermodynamics (FTT) by incorporating heat transfer irreversibilities through the ε−NTU formalism and a non-isentropic expansion modeled via the expander isentropic efficiency ηE.
