摘要
目的通过试验，找出静脉输液瓶盖消毒加药后有效消毒时限，确定再次消毒时间。方法取210瓶液体作为试验样本，分为7组，30瓶，组，按常规加药消毒，放置。分别在加药后即时及加药后的5，10，15，20，25，30min7个时间段对瓶盖进行采样，送细菌室进行细菌培养、鉴定。结果7个时间段瓶盖细菌污染情况比较χ^2=3．822，P〉0．05，菌种分布情况比较χ^2=25．32，P〉0．05，差异无统计学意义。结论静脉输液瓶盖消毒加药后在空气、物表细菌学监测结果符合标准要求的治疗室放置30min内其消毒效果仍达国家标准，在此时间段内更换该瓶液体，接瓶前无需重新消毒。
Objective To study the valid re-sterilizatlon time for capsules during the venous transfusion. Methods Divided 210 bottle of drugs for venous transfusion into 7 groups radomly, there were 30 bottles in the each group, and then sterilized according to the routine method. Sampling the capsules at the time points of dispensation immediately, 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes and 30 ＂minutes after the dispensation, and then observed the condition of bacterial pollution. Results There was no significant difference between the different sampling stages about bacterial pollution, χ^2=3.838 ,P〉0.05. There was no significant difference in the aspect of strain distribution, χ^2=25.32, P〉0.05. Conehlsions Re-sterilizatiou should not be done for the capsules during the venous transfusion ff in the normative cure unit and within 30 minutes.
