Abstract 【Objective】To investigate the disinfection effect and safety on anesthesia machine using circuit disinfection device. 【Methods】Our hospital had 38 close-circulated anesthesia machines that normally run during June 2017 to May 2018. Those anesthesia machines were sterilized by the device called anesthesia machine circuit loop sterilizer. The total number of colonies, the contaminated sites of the anesthesia machine, the incidence of patient infection and the metal corrosion at 3 months before and after anesthesia machine disinfection were recorded and compared. 【Results】The rate of anesthesia machine contamination was 28.95% (11/38) 3 months before disinfection, which was significantly higher than the contamination rate of 7.79% (3/38) 3 months after disinfection. The difference was statistically significant (P<0.01).There were no significant differences in the contamination rates between the inhalation end of the anesthesia machine, the outlet of the sodium-lime tank and the inlet of sodium-lime tube at 3 months before disinfection and 3 months after disinfection (P>0.05).The exhalation contamination rate of the anesthesia machine 3 months before disinfection was 18.42% (7/38), which was significantly higher than that of 5.26% (2/38) showed at 3 months after disinfection (P<0.01).The lung infection rate in patients 3 months before disinfection was 9.00% (9/100) and the respiratory infection rate was 14.00% (14/100), which was significantly higher than 2.00% (2/100) and 3.00% (3/100) , irrespectively, at 3 months after disinfection (P<0.05). The weight of carbon steel 72h after disinfection was significantly lower than that before disinfection (P<0.05). However, here was no significant difference in the weight of aluminum, copper and stainless steel 72h before and after disinfection (P>0.05). 【Conclusion】The use of 10% hydrogen peroxide by ultrasonic atomization disinfection of anesthesia machine can obtain a reliable disinfection effect, thereby reducing the contamination rate of anesthesia machine and patient respiratory infection, while improving the safety of anesthesia machine usage.
