Objective To analyze the effect of low temperature sterilization of ethylene oxide sterilizer in thecenter of disinfection supply room. Methods 80 sterilization packages in the center of the disinfection and supplyroom in recent 3 years (January 2019 February 2022) were selected and divided into two groups on average. Onegroup was the traditional low-temperature sterilization group (using 2% enhanced glutaraldehyde immersionmethod), and the other group was the ethylene oxide sterilizer low-temperature sterilization group (using ethyleneoxide sterilizer). Results There was no significant difference in sterilization effect between the two groups (P>0.05);Sterilization time of ethylene oxide sterilizer low temperature sterilization group was (900 ± 2.5) min, and that oftraditional low temperature sterilization group was (600.56 ± 11.46) min. It can be seen that the sterilization time ofthe former is longer (P<0.05); The storage time of ethylene oxide sterilizer low temperature sterilization group was（5.77 ± 1.10) months, and that of traditional low temperature sterilization group was (6.07 ± 1.07) months. It canbe seen that there was no statistically significant difference in storage time between the two groups (P>0.05).Conclusion The products sterilized by ethylene oxide sterilizer can be kept sterile for a long time, safe andeffective. Compared with traditional low-temperature sterilization, ethylene oxide sterilizer has strong advantagesin sterilization of instruments that are not resistant to high temperature and high temperature, greatly improving thesafety of surgery, and playing an important role in preventing hospital infection.
