软包装输液袋瓶盖不消毒的可行性分析

Feasibility study on the soft-packing transfusion bag cap without disinfection

目的：探讨软包装输液袋瓶盖打开后不消毒的可行性。方法取软包装输液袋瓶盖完整、无松动及裂痕的软包装液体共100袋，随机分为两组，实验组50袋瓶盖不消毒立即直接贴上瓶口贴，对照组50袋瓶盖用安尔碘消毒后立即贴上瓶口贴，将液体加药后放置于治疗室操作台上，并于0，15，30，120 min 4个时间段对瓶盖进行细菌采样和培养；便利抽签采样100袋软包装输液袋拉开拉扣后立即用瓶口贴贴好，分别在治疗室、病房以及使用安尔碘消毒后瓶口贴封口放置病房30 min后，观察瓶口细菌污染情况。结果输液袋贴瓶口贴后瓶盖表面无任何细菌生长；病房的输液袋瓶口细菌污染率12．12％，治疗室内瓶口无细菌生长，但两组比较差异无统计学意义（χ2＝1．56，P＞0．05）；同样放置在病房30 min的输液袋，瓶口使用安尔碘消毒后细菌污染率为8．82％，与未消毒瓶口比较差异无统计学意义（χ2＝3．82，P＞0．05）。结论软包装输液袋加药后的瓶塞是无菌的，开启瓶盖后可直接用于临床，但不建议在病房长时间放置。

opening the bags .Methods A total of 100 soft-packing transfusion bags with full caps , no loose and soft-packing liquid were prepared , and were randomly divided into two groups .In the experimental group with 50 bags,the caps were directly attached to bottle stickers without disinfection .In the control group with 50 bags, the caps were immediately attached to bottle stickers after Anerdian disinfection .After dosing liquid medicine , these bags were placed on the operating table in therapeutic room .Bacteria sampling and culture were at 0, 15, 30, 120 min four time periods.Through convenience sampling , 100 soft-packing transfusion bags were selected . The soft-packing transfusion bags were attach bottle stickers immediately after opening the bags , placing in the therapeutic room and wards , respectively, as well as the bags attached to bottle stickers after Anerdian disinfection placing in the wards .After 30 min, bacterial contamination on the cap was observed .Results After attaching the bottle stickers , there was no bacterial growth on the surface of the caps .The rate of bacterial contamination in the wards was 12.12%.No bacterial growth was found in the therapeutic room .But the＆amp;nbsp;difference between the two showed no statistical significance （χ2 =1.56, P＆gt;0.05）; after 30 min,the rate of bacterial contamination on the soft-packing transfusion bags also placed in the wards with Anerdian disinfection was 8.82%.Compared to no disinfection group , there was no significant difference （χ2 =3.82, P〉0.05）. Conclusions After dosing liquid medicine , the caps of soft-packing transfusion bags are sterile .After opening up,they can be used directly in clinical .But it is not recommended to place in the wards for long time .
