摘　　要：目的 观察4种包装材料器械包在压力蒸汽灭菌前后重量变化及湿包发生情况,为湿包判断提供依据。方法 采用随机区组设计,将2022年8—10月某医院骨科待灭菌复用骨科器械组装,按照规范随机使用棉布、无纺布、硬质容器或新型纺织品材料进行包装,在压力蒸汽灭菌器内使用相同程序进行灭菌;在灭菌前和灭菌完成后5 min内称重,并在冷却30 min后检查湿包发生情况。每种材料包装器械灭菌40例次,统计分析湿包例次发生率和灭菌后重量减少率。结果 4种包装材料器械包灭菌后湿包例次发生率差异无统计学意义(χ^(2)=3.490,P=0.322);160例次灭菌操作后发生湿包26例次,重量增加的有13例次,其中1例次包重量增加率>0.2%,而非湿包重量均无增加;4种材料包装的器械包灭菌后湿包重量减少率均小于非湿包(P<0.05)。结论 4种包装材料对湿包率的影响无明显差异,以灭菌后器械包重量增加作为湿包判断标准的准确性仍需进一步探索和验证。Objective To observe the weight change and occurrence of wet packs before and after pressure steam sterilization,so as to provide a basis for the judgment of wet packs.Methods A random block design was adopted to assemble the reusable orthopedic instruments to be sterilized in the orthopedics department of a hospital from August to October 2022.They were randomly packed with cotton cloth,non-woven fabrics,hard containers or new textile materials in accordance with the specifications,then the packs were sterilized by pressure steam.With the same procedure,weight of packs before sterilization and within 5 min after sterilization were weighed up.and wet packs were checked for after cooling for 30 min.All packs were repeatedly sterilized for 40 times,and the incidence rate of wet pack cases and the weight reduction rate after sterilization were calculated.Results There is no statistically significant difference among the four types of packaging materials in the incidence rate of wet pack cases after sterilization(χ^(2)=3.490,P=0.322).Wet packs occurred in 26 cases after 160 sterilization operations,There were 13 cases with weight increasing and the weight increase rate was>0.2%in a case,while the weight of non-wet packages did not increase.The weight reduction rates of wet packs after sterilization in four types of materials packages were all smaller than those of non-wet packs(P<0.05).Conclusion There is no significant difference in the wet pack incidence rate of four packaging materials.Using the weight increase of the package after sterilization as a wet pack criterion still needs further exploration and verification.
