【摘要】 目的比较甲醛熏蒸、三氧消毒机两种消毒方法对血库冰箱空气的消毒效果。方法甲醛熏蒸法是按40mL/m3用量,紧闭冰箱门,熏蒸2h;三氧消毒机消毒法是紧闭冰箱门开机2h,停机40min后使用。消毒前、后进行2次空气采样,培养48h,进行细菌菌落计数。结果两种消毒方法消毒前、后普通细菌数量及真菌生长情况比较,差异有统计学意义(P<0.01)。两种方法消毒后,细菌总数均在200cfu/m3以下,但甲醛熏蒸存在毒性残留问题,而三氧消毒机消毒法对人体损害较小。结论三氧消毒机消毒法消毒效果较好,且安装方便,在消毒过程中可开冰箱取血、发血。更多还原

【Abstract】 Objective To compare the efficiency of sterilization for blood bank refrigerator with the method of formaldehyde fumigating and tri-oxygen sterilizer.Methods The formaldehyde fumigating method was to fumigate the closed refrigerator with the 40 mL/m3 flow for 2 h.The method of tri-oxygen sterilizer was to run for 2 h with door closed and to use it 40 min later since shutting off.And then air sample before and after sterilization was cultured for 48 h and the bacterial colony was counted.Results There were significant differences before and after sterilization in the bacterial number and the growing status of mycetes(P<0.01).The total counts of bacteria were both below 200 cfu/m3 with the two methods,but there was some residual of toxicity with the formaldehyde fumigating method and little with tri-oxygen sterilizer.Conclusion It is better to use tri-oxygen sterilizer method has better sterilization efficiency,which is convenient to install and take in or put out blood during sterilization.更多还原
