Effects of ethylene oxide sterilization method on sterilization quality and damage of precision instruments
Objective To study the effects of ethylene oxide sterilization method on sterilization quality and damage of precision instruments.Methods A total of 800 precision instruments in the sterilization supply department of the hospital from March 2021 to December 2022 were selected and divided into ethylene oxide group(400 pieces)and plasma group(400 pieces)by random number table method.The ethylene oxide group was sterilized by ethylene oxide sterilization method,and the plasma group was sterilized by low temperature plasma sterilization method.The sterilization quality,damage,sterilization time and sterilization preservation time of the two groups of precision instruments were compared;in addition,40 hospital sterilization supply room staffs were selected to analyze the occurrence of adverse events in the two groups.Results There were no significant differences in the qualified rate of sterilization and the number of colonies on the surface of the instruments before and after sterilization between the two groups(P＞0.05);after sterilization,the number of colonies on the surface of the instruments in the two groups was less than that before sterilization,and the difference was statistically significant(P＜0.05).The total incidence of precision instrument injury in the ethylene oxide group was lower than that in the plasma group,and the difference was statistically significant(P＜0.05).The sterilization time of the ethylene oxide group was longer than that of the plasma group,and the sterilization preservation time was shorter than that of the plasma group,and the differences were statistically significant(P＜0.05).There was no significant difference in the total incidence of adverse events of staff between the two groups(P＞0.05).Conclusion The sterilization quality of precision instruments by ethylene oxide sterilization method and low temperature plasma sterilization method is comparable,and the risk of instrument damage by ethylene oxide sterilization method is lower than that by plasma sterilization method,but the sterilization time is longer and the sterilization preservation time is shorter.Therefore,the sterilization supply department should be reasonably selected according to the characteristics of precision instruments and the advantages and disadvantages of different sterilization methods.
