纸塑袋包装器械的灭菌质量研究

Study on sterilization quality of instruments with paper-plastic bag packaging

目的比较单层与双层纸塑袋包装器械对灭菌包压力蒸汽灭菌的灭菌效果、湿包发生、灭菌时密封线开裂的影响,以探索最佳包装方式。方法选择2013年11月1-30日单件需纸塑包装的器械共720件,随机分成对照组和试验组,对照组采用单层纸塑袋包装器械共362件,试验组在对照组包装基础上再外包装一层纸塑袋,纸面对纸面,塑面对塑面进行封口共358件,灭菌结束后检查器械包灭菌合格率、湿包发生率和密封线开裂率,采用SPSS 13.0软件进行统计分析。结果对照组与试验组包装器械灭菌合格率均为100.00%,湿包发生率分别为0.55%和0.84%,密封线开裂率均为0.28%,差异均无统计学意义,对照组与试验组包装器械对灭菌包压力蒸汽灭菌的灭菌效果、湿包发生、密封线开裂3项对比结果,差异均无统计学意义。结论双层纸塑袋包装器械灭菌效果可靠,灭菌时不会产生湿包和密封线开裂现象,可以作为单件器械的包装方式,在运输、贮存过程中减少包装破损,有效降低医院感染风险。

OBJECTIVE To compare the effects of single and double paper-plastic bag packaging on sterilization effectiveness,incidence of wet bag and seal line cracking of instruments,so as to explore the best way of packaging.METHODS A total of 720 pieces of instruments in need of paper-plastic packaging from Nov.1to Nov.30,2013 were randomly divided into the control group（362pieces）and the experimental group（358pieces）.The control group adopted single paper-plastic bag packaging,while the experimental group adopted double paper-plastic bag packaging in way of paper in face of paper and plastic surface in face of plastic surface to seal.The sterilization rate,the incidence of wet pack and the seal line cracking rate of instruments after sterilization were examined.The software SPSS13.0was used for statistical analysis.RESULTS The pass rate of sterilization was 100% and the sealing line cracking rate was 0.28%in both groups,the incidence of wet package rates were 0.55 and 0.84 respectively for the control group and the experimental group.There were no significant differences.There were no obvious differences in the effect of packaged instruments on pressuresteam sterilization effectiveness,the incidence of wet bag and sealing line cracking between the two groups.CONCLUSION Sterilization on instruments with double paper-plastic packaging is reliable,and the phenomenon of wet pack and seal line cracking is absent when sterilization.Thus,double paper-plastic packaging can be used as the packaging method for a single instrument,which can reduce packaging damage in the process of transportation and storage and effectively reduce the risk of hospital infections.
