摘　　要：目的探讨老年科医用织物的污染情况,并对抗菌织物的抑菌效果进行评价。方法自2016年12月1日-2017年6月30日以广东省3家大型三级甲等医院的老年科为基础,选取老年科常用的7类织物为研究对象,分别为床单、上衣、裤子、医护服、被套、枕套和布样共247份。将上述纺织物分为抗菌处理和非抗菌处理组,非抗菌处理的织物又进一步分为洗涤后使用与未使用组,采用3M PetrifilmTM测试片法进行细菌和真菌的菌落计数。结果纳入247份医院用织物品进行分析,抗菌和未抗菌处理的织物分别为59份(23.89%)和188份(76.11%)。洗涤后使用和未使用的织物分别为178份(72.06%)和69份(27.94%)。对医用织物使用情况进行细菌和真菌培养发现,使用过的织物(除医、护服外)细菌培养结果均高于未使用组(P<0.05),枕套、床单和上衣菌落计数最高为90(21,108)CFU/ml、63(30,127)CFU/ml、61(17,106)CFU/ml。真菌培养结果显示,使用过的枕套的真菌菌落数为7(1,10)CFU/ml高于未使用组(P=0.001),其余种类织物的培养结果差异无统计学意义。而对于抗菌效果评价发现,抗菌处理织物的细菌培养中位菌落数和最大菌落数均显著低于未抗菌处理织物(P<0.001)。两组织物的真菌菌落计数差异无统计学意义,但抗菌织物最大计数值仅为15 CFU/ml,未抗菌处理组为49 CFU/ml。结论枕套、床单和上衣是老年科最容易污染的织物,使用抗菌处理的织物可减少细菌的定植。OBJECTIVE To investigate the contamination of medical textiles in the department of geriatrics,and evaluate the effect of the antibacterial fabric.METHODS Samples of department of geriatrics were collected from 3 large Grade-A Tertiary Hospitals in Guangdong province from December 1,2016 to June 30,2017.Seven kinds of medical textiles,which had a total of 247 samples,including sheets,coats,trousers,uniforms,quilts,pillowslips and fabric swatches.All textiles were divided into antimicrobial group and non-antimicrobial group.Antimicrobial group received surface antimicrobial management and the non-antimicrobial group was untreated.The non-antimicrobial group was further divided into two subgroups,one subgroup can be used after washing and the other was unused.The count of bacteria and fungi was calculated by 3 M PetrifilmTM methods.RESULTS The total of 247 samples were analyzed.The numbers of bacteria in antimicrobial group and non-antimicrobial group were 59(23.89%)and 188(76.11%).The numbers of bacteria in used group and non-used group were 178(72.06%)and 69(27.94%).Base on the results of bacterial and fungal culture,we found that the number of bacteria of textiles(except uniforms)was significantly higher in used group than in the unused group(P<0.05).The median value(P25,P75)of the number of bacterial colonies observed in pillowslips,sheets and coats were 90(21,108)CFU/ml,63(30,127)CFU/ml and 61(17,106)CFU/ml,respectively.The median value(P25,P75)of the number of fungal colonies of pillowslips in used group were 7(1,10)CFU/ml,which was significantly higher than that in the unused group(P=0.001).But there were no significant differences between other textiles.Antimicrobial textiles showed better bacteriostatic effect compared with non-antimicrobial textiles.Antimicrobial textiles had lower median colony counts and maximum colony counts than non-antimicrobial textiles(P<0.001).The number of fungal colonies did not show the significant difference between both groups,although the maximum value of colonies in antimic
