摘要
目的 探讨不同处理流程对呼吸机管道及附件消毒的效果.方法 选取自2022年12月至2023年2月东部战区总医院消毒供应中心清洗消毒的呼吸机管道及附件250套,按使用先后顺序随机分为5组,每组50套,分别采用不同的清洗消毒方法:A组采用手工清洗+含氯消毒剂浸泡法,B组采用手工清洗+全自动清洗机,C组采用手工清洗+含氯消毒剂浸泡+全自动清洗机,D组采用加酶手工+超声清洗机+含氯消毒剂浸泡法,E组采用加酶手工+超声清洗机+全自动清洗机.于消毒后采集管道最难清洗消毒部位的标本进行细菌培养,比较各组清洗消毒效果.结果 经消毒,5组呼吸机管道均满足消毒标准规定要求,但E组湿化罐细菌数为(0.03±0.01)cfu/c㎡,呼吸机管道细菌数为(0.02±0.01)cfu/cm2,显著低于其他组(P<0.05).结论 呼吸机管道及附件的污染相当严重,5种方法均能达到高水平消毒,E组即加酶手工+超声振荡机+全自动清洗机效果最佳.
Abstract
Objective To explore the effect of different treatment procedures on the disinfection of ventilator pipes and acces-sories.Methods 250 sets of ventilator pipes and accessories from the disinfection supply room of General Hospital of Eastern The-ater Command from December 2022 to February 2023 were selected as the research objects,and randomly divided into 5 groups accord-ing to the order of use,with 50 sets in each group,and and different cleaning and disinfection methods were applied to different groups.Group A was treated with manual cleaning+chlorine-containing disinfectant soaking;Group B was treated with manual cleaning+auto-matic cleaning sterilizer;Group C was treated with manual cleaning+chlorine-containing disinfectant soaking+automatic cleaning steril-izer;Group D was treated with manual cleaning with enzyme+ultrasonic cleaning machine+chlorine-containing disinfectant soaking,and Group E was treated with manual cleaning with enzyme+ultrasonic cleaning machine+automatic cleaning sterilizer.The samples of the most-difficult-to-clean-and-to-disinfect parts of the pipes were collected after disinfection for bacterial culture.Results The re-sults showed that after disinfection,the 5 groups of ventilator pipes all met the requirements of the Regulation,but the bacteria number of the humidification tank in Group E was(0.03±0.01)cfu/c㎡,and the bacteria number of the ventilator pipe was(0.02±0.01)cfu/cm2,which was significantly lower than that of other groups(P<0.05).Conclusion The pollution of ventilator pipes and acces-sories is quite serious.All the 5 methods can achieve high level disin-fection,but the result of Group E-manual cleaning with enzyme+ultra-sonic oscillator+automatic cleaning sterilizer was the best.
