摘　　要：目的:探讨化学指示卡、胶带在灭菌过程测试中存在的问题,并找出解决问题的措施,以提高压力蒸汽灭菌器效果监测的质量。方法:采用脉动式压力蒸汽灭菌器,3M1250压力蒸汽灭菌包内化学指示卡,对100炉次中的各类手术包和敷料、储槽等采用相同的压力、时间、温度进行灭菌,并在灭菌完毕后对所有的试验包现场检查,并记录实际情况。结果:采取措施前有10个试验包内化学指示卡和包外化学指示胶带变色不标准。采取措施后未发现试验包内化学指示卡、胶带出现变色不标准的现象。结论:3M1250压力蒸汽灭菌包内化学指示卡变色不标准因素,受蒸汽灭菌过程中蒸汽冷凝水的影响。要使化学指示卡、胶带变为标准黑色,必须正确使用化学指示卡、胶带和规范物品包装及灭菌器。Objective To explore problems of chemical indicative cards and adhesive tapes in the disinfection, and find out some measures for improving the sterilizing effect of the pressure steam sterilizer. Methods 100 stoves of time with various package, dressing and storage tank were disinfected by pulse pressure steam sterilizer and chemical indicative cards of 3M1250 pressure steam sterilizing package at the same pressure, time and temperature. All test wraps were examined and the real conditions were recorded after the sterilization. Results The discoloration of chemical indicative cards in 10 test wraps was not standard before the measures were taken. While after that, it didn＇t occur again. Conclusion The nonstandard discoloration of chemical indicative cards of 3M1250 pressure steam sterilizer is influenced by condensed water of steam during the steam sterilization. In order to make the chemical indicative cards change into standard black, the accurate using of chemical indicative cards, the standard stuff package and correct using of disinfector are required.
