洁净手术室内干置无菌持物钳保存时间的研究

Research on the storage time of dry sterile forceps in clean operating rooms

目的探讨洁净手术室内干置无菌持物钳的保存时间。方法选择我院在百级、万级和三十万级洁净手术室内使用的干置无菌持物钳为研究对象,按照有无连台手术将其分为试验组与对照组,同一级别手术室内试验组与对照组各收集80把干置无菌持物钳,分别在4 h、6 h、8 h、10 h、12 h 5个时间点采样,并进行细菌学检测,比较干置无菌持物钳的合格率。结果洁净手术室内不同使用频率的干置无菌持物钳的合格率不同,百级、万级、三十万级洁净手术室内分别使用12 h、8 h、6 h的干置无菌持物钳,试验组与对照组比较,差异均无统计学意义(P(0.05)。结论只有一台较长手术比有连台手术的手术室内使用的干置无菌持物钳可以保存更长的时间,同时在百级、万级、三十万级洁净手术室内使用的干置无菌持物钳分别最多保存12 h、8 h、6 h。

Objective To explore the storage time of dry sterile forceps in clean operating rooms. Methods The dry sterile forceps in operating rooms with 100,10 000 and 300 000 cleaning levels were divided into the experimental group and the control group according to having continuous operations or not in the operating rooms,80 cases in each group. Then the samples were collected for the bacteriology examination at the five time points of 4 h,6 h,8 h,10 h,and 12 h. The qualified rates of the examination were compared. Results The qualified rates of the bacteriology examination among dry sterile forceps with different use frequencies was different. In the operating rooms with 100,10 000 and 300 000 cleaning levels, there was no statistical difference between the control group and the experimental group separately at the time points of 12 h,8 h and 6 h （ P 〉 0.05 ）. Conclusion The dry sterile forceps may save longer in the operation rooms with only a longer operation than those with continuous operations. The dry sterile forceps may save separately 12 h,8 h and 6 h in 100, 10 000 and 300 000 cleaning levels operating rooms.
