目的评价化学PCD在压力蒸汽灭菌批量监测中的应用价值。方法使用两种化学PCD装置现场监测预真空压力蒸汽灭菌器的灭菌效果。结果按预定程序进行灭菌,同时使用管腔型PCD进行监测,30次有3次不合格,使用3M公司的化学PCD进行监测则全部合格。修改灭菌器参数,增强抽真空效果,两种化学PCD监测结果均合格,生物监测也均合格。结论管腔型PCD在监测灭菌器的冷空气排除能力方面更敏感,尤其适用于使用年限较长的灭菌器灭菌过程的监测。
Objective To evaluate the value of chemical PCD in the batch monitoring of pressure steam sterilization. Methods Two chemical PCD devices were used to monitor the sterilizing effect of pre-vacuum steam sterilizer on site. The results were sterilized according to a predetermined procedure and monitored using a luminal PCD at the same time, three failed 30 times, and all were monitored using 3M’s chemical PCD. Modify the sterilizer parameters, enhance the vacuum effect, two kinds of chemical PCD monitoring results are qualified, biological monitoring are also qualified. Conclusions Lumen-type PCD is more sensitive in monitoring cold air removal of sterilizers and is especially suitable for the monitoring of sterilizing processes of longer sterilized sterilizers.
