摘　　要：目的 分析压力蒸汽、低温等离子及环氧乙烷3种灭菌方式对磁外科器件磁通量的影响及其灭菌成本。方法234件不同规格型号磁外科器件-磁环,配对编号标记后随机分为A组、B组和C组,每组78件(39对),其中A组使用压力蒸汽灭菌,B组使用低温等离子灭菌,C组使用环氧乙烷灭菌,每对器件按灭菌规范进行包装;测量3组磁环灭菌前后磁通量,对单包灭菌成本和灭菌时间比较分析。结果 3种灭菌方式对磁外科器件磁通量的影响差异无统计学意义(P>0.05),每种灭菌方式灭菌前后的磁通量有统计学差异(P<0.001);灭菌成本:A组为(1.96±0.16)元,B组(23.17±0.32)元、C组(8.16±0.18)元,差异有统计学意义(P<0.01);灭菌时间:A组为(65.21±3.36)min, B组(45.46±1.39)min, C组(1 020.38±12.21)min,差异具有统计学意义(P<0.01)。结论 3种灭菌方式对磁外科器件的磁通量没有影响。压力蒸汽灭菌法单包成本最低,低温等离子单包灭菌成本最高,环氧乙烷灭菌时间最长。压力蒸汽应为磁外科手术器件的首选灭菌方法。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.
