Three patients developed sternal surgical site infections post cardiac surgery with m.Abscessus.Following performance of environmental cultures of the water sources in and around the operating room, the only growth of m.Abscessus we have identified is within the reservoir and tubing of four cardioquip heater/coolers, leading us to believe that the heater cooler contributed to the surgical site infections.Manufacturer response for heater cooler, mch-1000 (per site reporter).Manufacturer said they would review cleaning protocols and will come in to do a refresher on cleaning and disinfecting of the heater coolers.
