可重复使用医疗物品包装方式的研究

Comparison of different packing methods for reusable disinfection medical instruments in hospital

目的探讨不同包装方式对消毒后可重复使用医疗物品存放有效期的影响,从而为临床应用提供依据。方法将供应室集中清洗、消毒、干燥后的湿化瓶、氧气面罩、呼吸机螺纹管、雾化通气管随机分为A、B两组,均使用市售食品包装袋包装,A组为独立包装,B组为10件为一组包装;采样监测10d内细菌污染情况。结果 A组7d内未出现污染,B组从第3天起出现污染;因包装方式的不同,两组消毒医疗物品的细菌污染程度差异有统计学意义(χ2=21.305,P<0.05);分离出的污染菌中61.33%在同病区患者标本中比对出耐药谱一致的菌株。结论使用独立包装的消毒后医疗物品在临床科室治疗室保存期限为7d,使用10件为一组包装者保存期限为2d。

OBJECTIVE To find out the storage life of disinfection medical instruments packed with different methods in hospital,so as to provide the basis for clinical application. METHODS After disinfection,the humidifiers,oxygen masks,pipes of ventilator,nebulization tubes were divided into group A（individual packs） and B（packed per 10 pieces）.The bacterial pollution rate was detected. RESULTS Group A haven′t been polluted in 7 days,yet group B were polluted from day 3rd.The pollution level was significant different between group A and B（χ2=21.305,P0.05）.The drug resistance of 61.33% bacteria polluted the instruments was in keeping with that of specimens isolated from patients at the same ward. CONCLUSION In therapeutic room,the storage life of disinfection medical instruments is 7 days when packed separately by food packs and that is 2 days when packed per 10 pieces.
