摘　　要：目的了解可重复使用透析器外壳细菌污染情况及两种不同消毒方法的消毒效果。方法将使用后的复用透析器经过全自动复用消毒机清洗、检测、消毒后,放入储存柜存放前,于不消毒、采用含有效氯500 mg/L消毒剂擦拭和浸泡消毒两种方式进行表面消毒后采样检测。结果 3组各100支灌满消毒液的复用透析器外壳细菌检测结果:未消毒组细菌菌落数平均为(15.52±3.81)CFU/cm2,合格率为87%;采用含有效氯500 mg/L消毒剂擦拭消毒组细菌菌落数平均为(3.22±0.71)CFU/cm2,合格率100%;浸泡在有效氯浓度为500 mg/L消毒剂内10 min组则未检出细菌,合格率100%。两消毒组与未消毒组合格率比较,差异均有统计学意义(χ2=7.89,P<0.05)。结论灌满消毒液的复用透析器外壳采用含有效氯500 mg/L消毒剂擦拭或将复用透析器整体浸泡在上述浓度的消毒剂内10 min,均能达到消毒要求,但后一种方法消毒灭菌效果更佳。Objective To realize the contamination of reusable dialyzer housing and efficacy of two different disin feetion methods on dialyzer housing. Methods 300 pieces of used dialyzers were cleaned, checked and disinfected by automatic disinfection machine, then divided evenly into three groups before stored in the cabinet, and specimens were taken from dialyzer housings without being disinfected, wiped with disinfectant containing 500mg/L available chlorine, and immersed with the same disinfectant, respectively. Results The average colony count of dialyzer hous- ings of three groups was as follows： nowdisinfection group was （15.52± 3.81 ）CFU/cm2, qualified rate was 87%; wiping disinfection group was （3.22 ± 0. 71 ） CFU/cm2 , qualified rate was 100 % ; qualified rate of immersing disin- fection group （immersion time was 10 minutes） was 100%,qualified rate between two disinfection groups and non disinfection group was different statistically（χ2 = 7.89,P（0. 05）. Conclusion Wiping and 10-minute immersion of dialyzer housings with disinfectant containing 500 mg/L available chlorine can both achieve disinfection efficacy, but the latter is better.
