一种被褥洗涤工艺对棉胎与床垫等携带细菌的清除效果

目的 探讨一种被褥洗涤工艺对棉胎、床垫等的消毒效果。方法 2018年11月—2019年1月随机选取某院住院部神经外科、普通外科、神经内科3个病区普通病房的部分棉胎、床垫、枕芯作为研究对象，采用一种被褥洗涤工艺对其进行消毒、检测，比较使用10、30 d以及清洗消毒前后其细菌数的差异。结果 三个科室共抽取72个床单位的棉胎、床垫、枕芯。采用该被褥洗涤工艺清洗消毒后，棉胎、床垫、枕芯上均未检出大肠菌群、金黄色葡萄球菌，普通外科棉胎、床垫细菌污染率均为4.2%，其余科室棉胎、床垫、枕芯细菌数均合格。细菌数神经外科和神经内科棉胎、床垫、枕芯患者使用10、30 d细菌数与清洗消毒后细菌数比较，差异均有统计学意义（均P<0.01）；普通外科棉胎患者使用10、30 d细菌数与清洗消毒后细菌数比较，差异均无统计学意义（均P>0.05），但床垫、枕芯患者使用10、30 d细菌数与清洗消毒后细菌数比较，差异均有统计学意义（均P<0.01）。结论 该被褥洗涤工艺对棉胎、床垫等消毒效果可靠，可以预防因棉胎、床垫、枕芯污染致医院感染的发生。

Effect of one kind of bedding cleaning technology on clearance of bacteria carried by cotton quilts,mattresses and so on

Objective To explore disinfection effect of one kind of bedding cleaning technology on cotton quilts, mattresses and so on. Methods From November 2018 to January 2019, partial cotton quilts, mattresses and pillow cores were randomly selected from the departments of neurosurgery, general surgery and neurology in a hospital, one kind of bedding cleaning technology was used to disinfect them, difference in bacterial colony after 10-day and 30-day use as well as before and after cleaning were compared. Results Cotton quilts, mattresses and pillow cores of 72 bed units were selected from three departments. After cleaned and disinfected with a kind of bedding cleaning technology, coliform bacteria and Staphylococcus aureus were not detected on cotton quilts, mattresses and pillow cores, bacterial contamination rates of cotton quilts and mattresses in department of general surgery were both 4.2%, bacterial colonies on cotton quilts, mattresses and pillow cores in other departments were all qualified. Bacterial colonies on cotton quilts, mattresses and pillow cores used by patients in departments of neurosurgery and neurology for 10 days and 30 days were both significantly different from those after cleaning and disinfection(all P<0.01); bacterial colonies on cotton quilts used by patients in departments of general surgery for 10 days and 30 days were not significantly different from those after cleaning and disinfection(both P>0.05); but bacterial colonies on mattresses and pillow cores used by patients for 10 days and 30 days were both significantly different from those after cleaning and disinfection(both P<0.01). Conclusion Disinfection effect of this kind of bedding cleaning technology on cotton quilts, mattresses and so on is reliable, which can prevent the occurrence of healthcare-associated infection caused by contamination of cotton quilts, mattresses and pillow cores.
