两种试验包B-D试验失败原因分析及对策

目的通过标准试验包与布巾包B-D试验效果监测分析,总结失败原因,找出相应对策,指导今后工作。方法对脉动真空灭菌器的真空有效性用两种试验包B-D试验进行研究。结果监测标准试验包与布巾包各400个,标准试验包成功396个,失败4个,成功率为99.0%;布巾包成功370个,成功率92.5%。结论由于布巾包制作不规范、蒸汽压力变化、灭菌器故障以及消毒员操作不规范等因素,是导致B-D试验失败的关键,而一次性标准试验包可减少人为因素的影响,使用方便所得结果可比性强,更加规范、标准。

Failure Causes Analyses and Corrective Actions of Two Different Types of Bowie-Dick Test Pack

OBJECTIVE To analyze the monitoring performance and testing efficacy and reliability of standardized disposable B-D test pack and standard linen test pack,and summarize the corrective actions based on failure analyses for future reference.METHODS The two different test packs were employed to evaluate the vacuum performance of dynamic air removal sterilizer.RESULTS We enrolled 400 standardized disposable B-D test packs and standard linen test packs respectively.The disposable pack failed 4 cases with the success ratio 99%,while the linen pack failed 30 cases with the success ratio 92.5%.CONCLUSIONS The poor conformity of hand-made linen test pack,variation of steam pressure,sterilizer failure,and unprofessionalism of sterilizer operator contribute as main failure causes in B-D test.Standardized disposable B-D test pack can decrease subjective factors significantly,and the test results are more reliable and standardized.
