采血人员手部细菌学监测调查

The monitoring analysis and significance of bacteriology from hand of blood collection staff

目的规范采血人员的操作规程,预防或控制采血过程中的感染。方法在采血者不更换手套的情况下进行手部细菌学监测采样,每次采血完毕后采样一次,连续采集10次,进行常规细菌学培养,并将培养结果进行细菌菌落计数及病原微生物学鉴定;每天1组,每组10人次,连续3d,取均值计算。结果采血人员的手在未采血前无菌,超过采血人数2人次时检出有菌落生长,并且菌落计数和致病菌均随着采样次数的增多而逐渐上升。结论采血人员每次完成采血后更换一次性医用薄膜手套,是预防感染的有效措施之一。

Objective To standardize the blood collectors′operation procedures ,prevent and control infection occurring during blood collection .Methods Conduct bacteriological monitoring and sampling of blood collectors′ hands without changing their gloves once after completion of each blood collection ,sample for 10 successive times ,start routine bacteriological culture ,record the quantity of bacterial clumps and make pathogenic microbiological identification of the cultured results 10 person times each group and one group a day for 3 consecutive days with the average values calculated .Results The blood collectors′hands were aseptic be-fore collecting the blood .When collecting blood for more than 2 person times ,bacterial clumps were detected on the hands ;the colo-ny counts and pathogenic bacteria increased with the rise of collect times .Conclusion Replacing the disposable medical film gloves after each blood collection is one of the most effective measures for prevention and control of infection .
