Abstract: 【Objective】 To analyze the effects of three sterilization methods, namely, pressure steam, low-temperature plasma and ethylene oxide, on the magnetic flux of magnetic surgical devices and their sterilization costs. 【Methods】 A total of 234 magnetic surgical devices of different specifications and models (magnetic rings) were randomly divided into Group A, Group B and Group C after the paired number was labelled, and each group consisted of 78 pieces (39 pairs). After packaging each pair of devices according to sterilization specifications, Group A was sterilized by pressure steam, Group B was sterilized by low-temperature plasma, and Group C was sterilized by ethylene oxide. We measured the magnetic flux of three sets of magnetic rings before and after sterilization, and comparatively analyzed the sterilization cost and sterilization time of the single package. 【Results】 There was no statistically significant difference in the impact of the three sterilization methods on the magnetic flux of the magnetic surgical devices (P>0.05), but there was a significant difference in the magnetic flux before and after sterilization for each sterilization method (P<0.001); the sterilization cost was (1.96±0.16) yuan for Group A, (23.17±0.32) yuan for Group B, and (8.16±0.18) yuan for Group C, showing statistically significant differences among the three groups (P<0.01). The sterilization time was (65.21±3.36) min for Group A, (45.46±1.39) min for Group B, and (1020.38±12.21) min for Group C, with statistically significant differences among the three groups (P<0.01). 【Conclusion】 None of the three sterilization methods affects the magnetic flux of the magnetic surgical devices. Pressure steam method shows the lowest cost of single package, low-temperature plasma method shows the highest cost of single package, while ethylene oxide method shows the highest sterilization time. Pressure steam should be the preferred sterilization method for magnetic surgical devices.
