可重复使用的消毒诊疗物品保存方法研究

Study for the storing methods of reusable disinfection medical instruments

目的探讨可重复使用消毒物品的保存期限,为临床应用提供依据。方法湿化瓶、面罩、呼吸机螺纹管、吸痰器连接管经清洗消毒后随机将:A组用预先经低温等离子灭菌后的食品包装袋按诊疗需求进行包装,B组放在铺好的治疗盘内;同时又将经A组包装后的诊疗物品随机分为A1组放在临床治疗室内,A2组放在供应室无菌室内,检测四组不同保存方法的污染率。结果 A组7d内未出现污染,B组1d出现污染,4d污染率达50.00%(P<0.05);A1组8d开始污染,A2组12d开始污染(P<0.05)。结论可重复使用的消毒物品在干燥无菌保存条件下,治疗室内保存时限为7d,供应室保存时限为10d。

Objective To find out the storage period of reusable disinfection medical instruments in hospital,and to provide the basis for clinical application.Method After disinfection,the humidifiers,atomized oxygen masks,screwed pipes of ventilator,connecting hoses of sputum aspirator were divided into group A（include A1 and A2） and B.They were preserved in different conditions.The bacterial pollution rate was detected.Method After disinfection,the humidifiers,atomized oxygen masks,screwed pipes of ventilator,connecting hoses of sputum aspirator were divided into group A（include A1 and A2） and B.They were preserved in different conditions.The bacterial pollution rate was detected.Result Group A haven＇t been polluted within 7 days,Group B were polluted in 4 days（P0.05）.Group A1 been polluted from 8th day,but group A2 has been polluted from 12th day（P0.05）.Conclusion When stored in dry aseptic surroundings,the storage period of disinfection medical instruments packed by sterile food packs were 7 days in therapeutic room and 10 days in sterile supply department.
