目的比较两种储存方法对纸塑包装压力蒸汽灭菌后物品质量的影响。方法分层抽取纸塑包装经压力蒸汽灭菌包180个,随机分为实验组和对照组,实验组灭菌后用一层塑胶袋密封后干燥储存;对照组灭菌后干燥储存。分别对两组灭菌物品采用裸眼目测和5倍放大镜观察包装袋质量。结果两组的包装袋质量比较1～8周差异无统计学意义(P>0.05);9～24周差异有统计学意义(P<0.001)。其中包装袋破损率裸眼目测为2.2%,5倍放大镜为10.0%,对照组9个包装破损的物品,7个有菌生长。结论纸塑包装压力灭菌物品采用塑胶袋密封后储存,能避免检查时反复触摸和环境因素引起的无菌包污染,较长时间保证无菌水平。
Objective To compare the effects of two storage methods on the quality of articles after autoclave sterilization. Methods 180 stratified samples were packed in pressure-packed plastic package and randomly divided into experimental group and control group. After sterilization, the experimental group was sealed with a plastic bag and stored dry. The control group was dried and stored after sterilization. Respectively, two groups of sterilized items with naked eye visual inspection and 5 times the magnifying glass bag quality. Results There was no significant difference in the quality of the two bags between 1 week and 8 weeks (P> 0.05). There was a significant difference between 9 and 24 weeks (P <0.001). Among them, the rate of bag breakage was 2.2% naked eyes, 10.0% of 5 times magnifiers, and 9 items of damaged packaging in the control group and 7 strains of bacteria. Conclusion Paper-plastic packaging pressure-sterilized items sealed with plastic bags after storage, to avoid repeated checks and environmental factors caused by aseptic package contamination, longer time to ensure aseptic levels.
