After discussing the factors damaging hydrogen peroxide low-temperature plasma sterile packaging bags (hereinafter referred to as Tyvek packaging bags), the damage rate of Tyvek packaging bags is lowered through the control of link quality, so as to guarantee the quality of sterile packaging bags and the safety of patients.
Design questionnaire and registration form by investigating 8606 instrument packaging bags sterilized by hydrogen peroxide low-temperature plasma from January 2019 to December 2019, the controllable factors damaging Tyvek packaging bags are analyzed from four aspects: instrument packaging, sterilization, transfer, and storage. By taking targeted interventions on 8155 instrument packaging bags sterilized from January 2020 to December 2020, the intervention effects of the key links and the damage rate are evaluated.
The main factors damaging Tyvek packaging bags mainly include improper transfer, storage, and management of instrument packing bags; improper use of instrument boxes; improper loading and uploading operations of sterilization; and the wrong size of packaging bags. For these factors, related intervention measures shall be adopted to control the link quality so as to lower the damage rate from 3.54% in the control group to 0.20% in the experimental group. The differences in damage rate are of statistical significance ( < 0.01).
Tyvek packaging bags are influenced by controllable factors. Through reasonable link control and standard operations, the sterile packaging bags can be kept sterile from the end of sterilization to the usage by patients, which guarantees the safety of patients and is worthy of reference.
探讨影响过氧化氢低温等离子体无菌包装纸袋（以下简称特卫强包装袋）破损的因素，通过环节质量控制降低特卫强包装袋破损率，保障无菌包装袋质量及患者安全。
设计调查问卷及登记表，对2019年1月至2019年12月8606个经过氧化氢低温等离子体灭菌的器械包装袋进行调查，从器械包装、灭菌、转运、储存4个方面分析影响特卫强包装袋破损的可控因素。对2020年1月至2020年12月灭菌的8155个器械包装袋采取针对性干预措施，评价关键环节的干预效果及破损率。
影响特卫强包装袋破损的主要因素包括器械包装袋转运、储存及管理不当；器械盒使用不当；灭菌装载及卸载操作不当；包装袋尺寸错误。针对这些因素采取相关干预措施控制环节质量，使破损率从对照组的3.54%降至试验组的0.20%。破损率差异有统计学意义（<0.01）。
特卫强包装袋受可控因素影响，通过合理的环节控制及规范操作，可使无菌包装袋从灭菌结束至患者使用全程保持无菌状态，保障患者安全，值得借鉴。
