Major health risk in using heater-cooler devices for heart surgeries

Heater-cooler devices are often used during open heart surgeries and also for those involving the lungs. They help in warming or cooling the patient as required. It includes of two devices - a tank that provides temperature controlled water and an external heat exchanger that has been linked with devices that keep circulating blood and organs at a specific temperature depending on the type of surgery being performed. 

However, a new study suggests that they may pose a major health risk to patients. As per a new research presented at the annual conference of the Association for Professionals in Infection Control and Epidemiology (APIC), one in three heater cooler devices may be contaminated with deadly bacteria.

The research was presented by John Rihs, vice-president of laboratory services at Special Pathogens Laboratory who along with his team examined 89 heater-cooler units used across 23 hospitals in Canada and the United States between 2015 and 2016. Shockingly, it was found that 33 units out of the total (or 37 per cent), tested positive for a certain type of bacteria called M chimaera, while four units were colonised with Legionella, according to a global media report.
