连续采血手套表面污染后消毒效果及成本分析

Disinfection effect of gloves for continuous blood sampling after surface contamination and cost analysis

目的评价在连续大量采血过程中不换手套采用手套消毒的消毒效果及时间、成本的比较。方法从门诊患者中随机选择59例,在连续采血过程中不换手套。每次采血前用1mL 3M免洗手消毒液（含葡萄糖酸氯已定0.45%~0.55%w/v,乙醇水平63.1%~77.0%v/v）采用六步洗手法的方式进行手套手消毒,再进行消毒效果细菌学监测及时间、成本的比较。结果在59例标本中,细菌菌落总数均小于或等于10CFU/cm2,未检出金黄色葡萄球菌、大肠杆菌等致病菌。59例患者仅使用了一双手套和59mL消毒液,总价为6.33元。而全部更换59双手套则需要129.80元。因此,节约了123.47元的成本。如每次换手套和手消毒的时间为1min 20s,59例标本则可以减少49min。结论在采血后,用快速消毒液采用六步洗手法消毒不仅能有效替代在每个患者采血后更换手套和做手消毒,还能节约时间和成本。

Objective To evaluate the effect of adopting the glove disinfection without changing glove during the process of a large numbe of continuous blood specimen collection and to conduct the comparison of the time-taken and the cost. Methods 59 outpatients were randomly selected as the samples. The gloves were not changed during the process of continuous blood sampling. Before collecting blood sample, lmL 3M hands-washing-free disinfectants （containing chlorhexidine gluconate 0.45 %- 0.55% w/v and ethanol 63.1%- 77.0 %v/v） was adopted to disinfect the gloves by the 6-step hand-washing method. The disinfection efficiency and the bacterial monitoring were per- formed. Then the time-taken and the cost were compared. Results Among 59 samples,the bacterial colony count was ≤10 CFU/cm2 and the no pathogenic bacteria of Staphylococcus aureus and Escherichia coli were detected out. 9 out- patients used only one pair of gloves and 59 mL disinfectants with the cost of 6.33 Yuan. But changing all 59 pairs of gloves needed 129, 80 Yuan. Therefore,the cost of 123.47 Yuan was saved. The time for changing gloves and hand disinfection every time was 1 min 20 s,59 samples could be decreased by 49 min. Conclusion Using the rapid disin- fectants for the gloves disinfection by 6-step handwashing method after blood sampling not only can effectively re- place the gloves change and hand disinfection after collecting blood for each outpatient, but also can save the time- taken and the cost.
